New description: [New technical field] This creation provides a quick-release structure, especially a quick-release joint that can easily connect the drive head to a pneumatic tool. [Prior Art] Referring to the first figure, a conventional drive head cymbal is shown coupled to a quick release joint 2 having a sleeve portion n and a drive portion 12 that can drive a screw or the like. The tubular portion η has a connecting hole ln, the inner wall of the connecting hole ui has an annular groove 112, and the quick-release joint 2 has a first end 21 and a second end 4, and the first end 21 can be assembled For example, a pneumatic tool (not shown) is provided on the hand tool, and the second end 22 has a chamber 221 in which a spring 23 and a ball 24 are received. After the connecting hole 该 of the driving head 1 is sleeved with the second end 22 of the quick-release joint 2, the spring 23 biases the ball 24 and causes the outer side portion 241 of the ball 24 to protrude from the chamber 221 and combined with the trench 112. Thus, the drive head can be locked to the quick release joint 2, and when the quick release joint 2 coupled to the pneumatic tool is rotated, the drive head 1 is driven. To remove the drive head i from the quick release joint 2, the user usually holds the drive head 1 and the grip of the pneumatic tool and applies force to pull the two apart, forcing the ball μ to retract to the capacity. Within the chamber 221, the drive head cartridge is removable from the quick release joint 2. However, it is often difficult to detach the drive head 1 from the quick release joint 2, in particular, when the ball 24 is stuck or the user's hand is oiled; in addition, when the elastic (2) elastic force is lowered When the driving head 1 is detached during the operation of the pneumatic tool, in particular, when the screw or the like driven by the driving head 1 is located in the deep hole, the driving head 丄 may fall off and get stuck when exiting. Inside the deep hole. [New Content] The main purpose of this creation is to provide a quick-release joint structure that allows the drive head to be securely assembled to a pneumatic tool and allows the drive head to be easily removed and replaced from a pneumatic tool. The quick release joint formed according to the present invention comprises a shaft, a sleeve sleeve slidably sleeved on the shaft, a ball and a magazine; the shaft has a fitting for the pneumatic tool ^ a first end and a second end, the second end having a recess, the recess enclosing a first shallower contact section near the end of the second end and a second deeper contact section; The sleeve includes a first end, a second end for the drive head assembly, and a shaft hole extending through the jth end and the second end and providing a shaft, the second end of the sleeve comprising: the shaft hole Wei_direction hole, the alignment hole can be aligned, the rod_part·the circle=, the radial hole of the sleeve moves in the radial direction and can move along the axial direction of the shaft to receive the concave portion of the shaft Innerly coupling the shaft to the sleeve; the magazine is assembled in the axial bore and biases the sleeve toward the second end of the shaft with respect to the shaft axially opposite the shaft The first position of the elastic cyanine and the second position between the retracted cymbal, when the sleeve is biased by the biasing Z::LT is in the first contact section of the recess and the circle Bead - set _ ” θ 4 (four) hole The first hybrid material of cis Weike County - position when in the first position of the ball line portion of the recess ,, brother a linker such that the drive rod can be separated from the quick release of the control .a does not protrude to the wells, 6

The first end 421 has a plurality of grooves 428 around the outside of the first end 421 for facilitating the user's grip; a shaft hole 423 is formed in the first end 421. The enlarged portion 424 has an end surface 427'. The second end 422 of the sleeve further includes a radial hole 425 communicating with the shaft hole 423. The radial hole 425 can be aligned with the shaft 41. Concave portion 415. In this embodiment, the second end 422 of the sleeve has a quadrangular cross section and is whip-leaf at the second and second ends. ^ 421 The driving head 3 includes a sleeve portion 31 and 32' having a connecting hole 311. The connecting hole 311 has a square cross section and is coupled to the second end 422 of the sleeve 42. A groove 312 is defined around the connecting hole 311. The ball 44 is radially movable in the radial hole 425 of the sleeve 42, and the ring 45 is assembled in the radial hole 425. In the outer end, the ring 45 has a smaller diameter than the ball 44, so that only a portion of the ball 44 can protrude from the radial hole; the second ball 44 can be along the axial axis of the shaft 41 The shaft 41 is coupled to the sleeve 42 in the shaft μ concave portion 5. The bullet 43 is assembled in the axial hole 4 of the sleeve 42 = _ rod, so that the sleeve 42 is movable along the mowing shaft 41 between a forward first position biased by the spring 43 (as shown in the fourth 8 M338139) and a second position retracting the spring 43 (eg, eighth) In the present embodiment, the spring 43 is seated in the enlarged portion 424 and has a first end 431 against the shoulder 414 of the shaft 41 and an end face of the enlarged portion 424. On 427 Two ends 432. Referring to the fourth figure, when the sleeve 42 is moved to the first position, the sleeve 42 pushes the ball 44 to the first contact section 416 of the recess 415; the first contact The depth of the segment 416 is such that when the ball 44 is positioned to the first contact segment 416 of the recess 415, an outer portion 441 of the ball 44 may protrude from the radial hole 425 or the second end 422. Referring to the seventh figure, when the sleeve 42 is moved to the second position of the retreat, the ball 44 is moved from the first contact section 416 of the recess 415 to the second contact section 417, the second contact section 417. The depth is such that when the ball 44 is raised to the first contact portion 417 of the recess 415, the ball 44 does not protrude from the surface of the radial hole 425 or the second end 422. In combination with the quick release joint 4, referring to the seventh figure, it is shown that when the drive head 3 is initially assembled to the quick release joint 4, the drive head connection hole is made. The side wall will press the ball 44 and push the The sleeve 42 is inwardly inclined with respect to the shaft 41. The yellow 43 is seen; referring to the figure, the sleeve 42 is moved to the second position of the retreat and the spring 43 is retracted. The ball 44 is shown moving from the first contact segment 416 to the second contact segment 417, at which point the ball 44 is fully retracted into the second end 422 of the sleeve 42 to enable the second end 422 to advance further. Entering the interior of the drive head 3; see ninth diagram 'showing that the drive head 3 is further moved to contact the radial flange 426 of the sleeve 42, and the ball 44 is shown to be in opposition to the groove of the drive head 3. Then, when 9 M338139 releases the pressure on the driving head 3, the spring 43 biases the sleeve to move together with the driving head 3 to the first position of the forward extension, as shown in the second figure, the circle The bead 44 is positioned in the first contact segment 416 of the recess 415 and is coupled to the _ 312 of the drive _3 so that the drive head 3 will be securely coupled to the quick release joint 4 (as shown in Figure 6). And when the quick release joint 4 assembled on the pneumatic tool 5 is rotated, the drive head 3 is driven.
