[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] Reference Figure 1-3 , this specific implementation adopts the following technical scheme: a two-jaw rear-pull chuck fixture, including a claw chuck body 1, a first pull rod 2, a clamping claw 3, a flange 4, a second pull rod 5, a cover plate 6, a threaded adapter 7, a support block 8, a first limit screw 9 and a second limit screw 10. The rear end of the claw chuck body 1 is installed on the flange 4, and a threaded adapter 7 is arranged at the center of the flange. The threaded adapter 7 is connected to the second pull rod 5 at the center of the clamping claw plate body 1, and the two ends of the second pull rod 5 are connected to the two first pull rods 2. The first pull rod 2 is inclinedly matched with the inner wall of the claw chuck body 1, and the end of the first pull rod 2 is fixed with the clamping claw 3, and the front end of the second pull rod 5 is provided with a cover plate 6, and a support block 8 is fixed on the cover plate 6. A processing part A is placed on the support block 8, and the inner wall of the clamping claw 3 is tightly matched with the processing part A. The claw chuck body 1 is also limitedly matched with the first pull rod 2 through the first limit screw 9 and the second limit screw 10.

[0017] It is worth noting that the first tie rod 2 is a diagonal tie rod.

[0018] It is worth noting that a limiting groove 21 is provided on the outer wall of the first pull rod 2 and a limiting screw hole 11 is provided on the claw chuck body 1. The limiting screw hole 11 is limitedly matched with the limiting grooves 21 on the two first pull rods 2 through the first limiting screw 9 and the second limiting screw 10.

[0019] It is worth noting that an inclined sliding hole 12 is provided in the claw chuck body 1, and the inclined sliding hole 12 is slidably matched with the first pull rod 2 to achieve the loosening and clamping of the claw.
