Description of the invention: (1) [Technical field to which the invention pertains] The operational tool of the present invention, which can be rotated and adjusted, is a solution to improve the problem of the problem encountered in the operation of the general tool and promotes the improvement of the function. Technical method. It mainly locks the safety anti-off-type column through the head of one end of the operating tool and locks it on the internal screw hole of the operating body. A manual and simple coupling clutch device is formed. The use of the inner tooth groove and the outer ring gear to engage and disengage the principle to achieve the purpose of bending the force and the idling force. This in turn facilitates quick screwing of the nut to save operating time. • [Prior Art] =, currently in the hand tools seen in the market, a variety of handles have appeared. The purpose is to solve the ratchet socket wrench, because the plate screw:: the gas operated handle is limited angle after a certain angle and the quick-turning and labor-saving fiber type. Now, the wheel ratchet socket wrench shaft can be simultaneously Solve the problem that the wrench is limited by the angle of the force applied by the wrench and the quick turn and labor saving. However, the number of parts is large, in order to take into account the strength of the wrench and the precision of the group, the inventory, the price, and the low price. At 5 o'clock, the manufacturing and operating costs were greatly reduced due to the reduction in the number of revolutions. The design of many ring-toothed ratchet socket wrenches on the market was not deviated. There is a need for further research and improvement. As an example, see Taiwan Patent Gazette No. M336114: Designing the first structure of the structure _ and the second diagram of the angle configuration shown in Fig. 4' is placed by the threaded rod (4) of the round rod (4G) Through the board page 3 201213058
