[0030] To enable those skilled in the art to fully understand the technical solution, this application provides the following overall overview:

[0031] When in use, you can choose a suitable clamping piece at will according to the shape of the workpiece. When it is necessary to clamp and fix the disc-shaped shell-shaped workpiece, pinch the hollow cylindrical frame 54 to pull the bottom plate 51 to the top of the inner wall of the square groove 3, and fix the position of the bottom plate 51 by the first screw 52. At this time, the arc positioning plate 59 is above the support platform 1, and the two opposite arc positioning plates 59 are held. The two arc positioning plates 59 will push the connected rotating rods 58 to retract. When the rotating rods 58 are retracted, the other end pushes the slide plate 56 upward, and the slide plate 56 squeezes the spring 57 and pulls the other two rotating rods 58 to retract, so that the four arc positioning plates 59 are brought together, and the disc-shaped shell-shaped workpiece is placed on the outside of the four arc positioning plates 59. Loosen the arc positioning plates 59, and the spring 57 pushes the slide plate 56 down to extend the rotating rod 58. The rotating rod 58 will push the arc positioning plates 59 to expand and clamp the inner side of the disc-shaped shell-shaped workpiece to fix it.

[0032] When it is necessary to clamp a rectangular shell workpiece, the workpiece is directly placed on the outside of the square shell clamping part. The spacing and position of the outer panel 510 and the side panel 511 can also be adjusted according to the size of the workpiece. The outer panel 510 or the side panel 511 is pulled a certain distance away from the support platform 1. The pulling distance is determined according to the dimensions marked on the first connecting plate 514 and the second connecting plate 515, and the first connecting plate 514 and the second connecting plate 515 are fixed by rotating the corresponding first studs 512 and second studs 513. In this way, the outer panel 510 and the side panel 511 are fixed. It is suitable for workpieces of various sizes.

[0033] When it is necessary to clamp a rod-shaped workpiece, pull the two support seats 518 upward and use the second screw 519 to fix the support seat 518, and place the two ends of the rod-shaped workpiece between the clamping head 520 and the positioning head 521 for fixation. At the same time, the position of the two side plates 511 can be adjusted to change the distance between the clamping head 520 and the positioning head 521, so that workpieces of various rod-shaped sizes can be clamped, thereby increasing the scope of application.
