In the present embodiment, the first central axis AA', the second central axis BB', and the third central axis CC' are located on the same plane (not shown). The first central axis AA' and the second central axis BB' are coaxial. The third central axis CC' is perpendicular to the first central axis AA' and the second central axis BB'. In this embodiment, the first bumps 12 and the second bumps 13 are symmetrical with respect to the third central axis CC'. The locating pin 15 is fixed to the base 10 on the third axis CC' for limiting the position of the workpiece 200 in the direction of the third axis CC'. The first slider 20 includes a first clamping portion 21, a first sliding portion 22, and a first abutting portion 23. The first sliding portion 22 cooperates with the first slide 120. The first slider 20 is moved in the direction of the first central axis AA' by the cooperation of the first sliding portion 22 and the first slide 120. The first clamping portion 21 is for abutting against the workpiece 200. In the present embodiment, the first clamping portion 21 and the first sliding portion 22 are perpendicular to each other to form a T-shaped structure. Of course, the first clamping portion 21 can also take other shapes that facilitate clamping, such as a semi-circular configuration, depending on the shape of the workpiece 200. In the present embodiment, the first abutting portion 23 is an arcuate surface. In order to provide the first slider 20 with a restoring force away from the workpiece 200, the mounting and removal of the workpiece 200 is facilitated. The first elastic member 30 is restrained on the first slider 20 by a snap ring 31 and a blocking piece 32. In the present embodiment, the first elastic member 30 is a spring. The first elastic member 30 - the end 30 a abuts against the first protrusion 12 , the other end 30 b abuts against the blocking piece 32 , and the blocking piece 32 abuts against the first The snap ring 31 of the slider 20 V 〇 098126853 Form No. A0101 Page 7 / Total 15 page 0992046013-0 201105463 The second slider 40 is the same as the first slider 2 结构. The second slider 40 includes a second clamping portion 41, a second sliding portion 42, and a second abutting portion 43. The second sliding portion 42 cooperates with the second sliding channel 13〇. The second slider 40 is moved in the direction along the second central axis BB by the cooperation of the second sliding portion 42 and the second sliding passage 130. The second clamping portion 41 is for abutting against the workpiece 2〇〇. In the present embodiment, the second abutting portion 43 is an arc structure. [0015] In order to provide the second slider 40 with a restoring force away from the workpiece 2, the mounting and removal of the workpiece 200 is facilitated. The second elastic member 5 is restricted to the second slider 4 by a snap ring and a baffle 52. The second elastic member 50 in the present embodiment is a spring. One end 5〇a of the second elastic member 5() abuts against the first protrusion 13 and the other end 5〇b abuts against the blocking piece 52, and the detecting piece 52 abuts against the engaging piece 52 On the snap ring 51 on the second slider 4''. [0016] The second slider 60 includes a working portion 61, a sliding portion 62, and a button 63. The working portion 61 is a U-shaped structure. The working portion 61 includes a first extension arm 610 and a second extension arm β11. The first extension arm ο and the second extension arm 611 are oppositely disposed. The first extension arm 61 〇 includes a first slope 6i 〇 a. The first slope 610a includes a first end away from the sliding portion 62 61〇b and a second end 61〇c adjacent to the sliding portion 62. The first inclined surface 610a abuts against the first abutting portion 23 of the first slider 20. The second extending arm 611 includes a second inclined surface 611a. The second inclined surface 6113 is opposite to the first inclined surface 610a. The first inclined surface 61〇a includes a third end 61 lb away from the sliding portion 62 and a portion close to the sliding portion 62. The fourth end 611c.

The second inclined surface 61 la abuts against the second abutting portion 43 of the second slider 4A. The sliding portion 62 is opposite to the third sliding passage 14 The third slider 60 is moved in the direction of the third central axis CC' by the cooperation of the third sliding portion 62 and the third sliding channel 14A. [0018] Ο The button The third elastic member 7 is sleeved on the sliding portion of the first main slider 6 62, and compressed between the second bump 14 and the button 63. The elastic force provided by the third elastic member 7〇 is much larger than that of the first elastic member 3〇 and the second elastic member 5〇 When the workpiece 200 is ready to be loaded, the third slider 60 is pushed in the direction eight, and the first slope 6丨〇a and the second slope 6丨丨a of the third slider 60 are opposite to the first The slider 20 and the second slider 4 are moved, because the distance between the second end 610c and the fourth end 611c is greater than the distance between the first end 61 (10) and the third end 611 b. The spacing between the slider 2 and the slider 40 will increase under the elastic force of the first elastic member 3〇 and the second elastic member 5〇 when increased to a suitable distance. Inserting the workpiece 2 into the first clamping portion 21 and the second clamping portion 41 to release the third crushing 60, the third sliding member 60 in the third elastic member 7〇 of the elastic force moves in a direction opposite to the direction 4. The first inclined surface 610a and the second inclined surface 6111a move relative to the abutting slider 20 and the second sliding block 4〇, due to the first end 610b and The distance between the second ends 611b is smaller than the second ends 6丨 and the & 098126853
