New description: [New technical field] [0001] A safety protection mechanism for pneumatic tools, especially a pneumatic tool that adds a protective mechanism by adding a safety start button and a linkage mechanism. [Prior Art] [0002] Small power tools (including pneumatic or electric) are popular because of their small size, low price and low energy consumption, and the power tools include a variety of variations, such as grinders and drills. Pneumatic (electric) wrenches and other types. [0003] A conventional power tool can be found in Chinese 泯: National Patent Publication No. 40 1 908, "Improvement of the safety structure of a push switch of a power tool", which is defined as a press-open relationship side frame on a pneumatic tool body The air is controlled above the valve stem, and the other side of the push switch is provided with a long slot and two perforated lugs are preset, and the safety member can be inserted through the pin member through the long slot. And the pin member is bored with a torsion spring that abuts against the inner end surface of the push switch and the other side abuts the safety stop, and has a stop edge above the safety stop The angle between the aforementioned safety stop and the grip of the pneumatic tool body is an obtuse angle, so that the safety stop can stop the pressing switch, so that the pressing switch can not be pressed down, and the air control lever is not pressed down. When it is intended to be used, the safety stop must be pivoted forward to press the push switch to press the interlocking air control valve stem; the feature is that the push switch has a slot under the safety stop. For A pulley is provided, and when the safety stop is pivoted forward, the frictional resistance can be reduced by the lower pulley contacting the upper end surface of the grip of the pneumatic tool body form No. A0101, page 3 of 19 M399004, relative to The pivoting action is smoother and smoother, and the operation is more convenient and convenient. However, the safety stop is mounted on the exterior of the power tool and is an easily movable stopper structure, and the child or the pet in the home may be accidentally touched and opened. When the pulley is installed under the safety stopper, it is more likely to be displaced due to vibration or collision. The stop state is extremely easy to accidentally touch and start to cause danger. [0004] Another prior patent, such as the Republic of China Patent Certificate No. M259674 "Improvement of a pneumatic tool safety start switch", the prior patent discloses a pneumatic tool mounting a push button and a linkage block, the push button and the linkage block According to the user's push, the movement of the stop plate can be selected to prevent the child from accidentally touching the pressure plate or other unintentional mistakes. [〇005] The conventional pneumatic tool protection mechanism moves the trigger of the tool to prevent easy opening by restricting the trigger action. However, under the experience of actual operation, it has been found that the operator does not develop a good use habit. The conventional safety switch can be dangerous at any time as long as there is no mechanism for automatically returning to the locked state after opening. According to the experience of the operation, if the pneumatic tool is operated with one hand during use, it may cause danger due to improper operation and excessive power output, which makes the user unable to operate stably. [New content] [0006] Since the conventional pneumatic tool safety mechanism fails to completely avoid malfunction, and if a pneumatic tool is used with one hand, it may be dangerous because the power is too large or the operator is not clenched. Therefore, the purpose of the present invention is to provide an improved safety protection mechanism that adds a protective mechanism by adding a safety start button and a linkage mechanism that interlocks with the safety start button.

Therefore, if the safety start button is not pressed at the same time, the pneumatic work can be avoided: · - ϊ, with a false start. Moreover, the user can operate the pneumatic tool together with both hands to ensure safe operation. [Embodiment] [0009] This case is a safety protection mechanism for a pneumatic tool. The technical content of the present invention will be described below with reference to the drawings. Please refer to FIG. 1 , FIG. 2_丨 and FIG. 2_2 , which show that a pneumatic tool comprises a casing 丨, an actuating mechanism 4 accommodated in the outer shout 1 , and an intake passage formed by the outer casing 1 . 14. A force control to determine whether to allow airflow through the intake control mechanism of the intake passage 14, in addition to the intake passage 14, the outer casing may be provided with a discharge passage 16 for exhausting exhaust gas or dust. The intake control mechanism includes a trigger 2 mounted on the outer casing 1 and a push switch 3 controlled by the trigger 2 to control the airflow. In the embodiment shown in the figure, the housing has a support portion 10, and the trigger 2 has a pivoting portion 20 pivotally connected to the support portion 10. The operator can press the trigger by applying a force to the trigger 2 Switch 3. It can be seen in FIG. 2-1 and FIG. 2-2 that the push switch 3 has a blocking portion 31, and the outer casing 1 is provided with a switch retracting space 13 for the push switch 3 to have a moving space, and a closing member 33 is disposed on the The switch 1 is closed to the surface of the outer casing 1 and an elastic member 32 is disposed between the closure member 33 and the blocking portion 31. Therefore, when the trigger 2 is unstressed, the elastic member 32 is blocked in the intake passage 14 by the blocking portion 31; when the trigger 2 is forced to push the push switch 3, the air introducing passage 14 is Enter the switch retraction space 13. The structure of the pressure switch 3 is a conventional technical powder in the technical field, and the focus is not on the structure of the trigger 2 and the push switch 3, so the air intake control is not limited in this case. The specific type of mechanism, the trigger 2 and the push switch 3 in the drawing are only one of the states that can be specifically implemented. In Fig. 2-2, it can also be seen that the "Xuanwai double 1 inner valley has a rolling drive", the mechanism 4 can be connected to an auxiliary tool 5 (such as a grinding disc). The actuation mechanism 4 and the "Xiao auxiliary tool 5 are also conventional technologies in the technical field, and therefore will not be described again. The present invention is characterized in that the pneumatic I tool comprises: an ampoule number A0101 (four) 6 disposed on the outer casing i, a linkage mechanism interlocked by the safety start button 6, and a detailed structure of the lock member being pushed by the linkage mechanism. - and referring to the circle 3 2, the casing 1 has a groove 丨丨 accommodating the safety starter L and the groove 11 is provided with a - elastic element 61 abutting the safety starter to make the safety start button 6 It is in the normal position when it is not stressed. The linkage mechanism includes a continuous reduction 62 and a connection, and the M399004 button 6 is connected to the linkage rod 62. The linkage rod 62 passes through the outer casing 1 and the other end is connected to the linkage block 63. The housing 1 is further provided with a rail 12 for moving the linkage block 63 of the linkage mechanism. A resilient member 65 is disposed in the rail 12 to abut the linkage block 63, and an auxiliary limiting member 64 is further disposed under the linkage block 63. . The latching member 7 is adjacent to the linking block 63. The latching member 7 has a head end 70 and a latching portion 71, and the housing 1 also has another latching member retracting space 15 for the latching member 7 to have The space for the event. A closure member 73 is assembled on the outer casing 1 to close the latching member retracting space 15, and an elastic member 72 is disposed between the closing member 73 and the latching portion 71 to normally abut the latching portion 71. Due to the ejector of the resilient member 72, the latch portion 71 is normally in a locked position that enters and blocks the intake passage 14. Further, due to the clogging of the lock portion 71, even if the switch 2 is pressed by the wrench 2, the air flow cannot pass through the latch portion 71, and the actuating mechanism 4 cannot be operated. [0010] Please refer to FIG. 4-1 and FIG. 4-2 again. To drive the pneumatic tool to start working, the operator needs to simultaneously press the trigger 2 and the safety start button 6, and press the trigger 2 as previously described. The push switch 3 can be interlocked to control the flow of air through the intake passage 14. Pressing the safety trigger 6 can drive the linkage block 63 through the linkage rod 62. The movement of the linkage block 63 can move a push top 631 together, and the push top 631 moves to push the latch member 7 The head end 70 moves the latch member 7 toward the latch retracting space 15. As the latch member 7 moves, the latch portion 71 also begins to move away from the intake passage 14 to an open position, thereby preventing the intake passage 14 from being blocked by the latch portion 71. Thus, the introduced air flow can drive the operating mechanism 4 through the air flow passage 14. As shown in Figures 3-2 and 4-2, the push top 631 can be a continuous inclined surface to push the latch member 7 to move stepwise.
