The front end of the clamping plate 61 is slidably connected with a rack 65 for driving the side clamping block 63 to move. The rack 65 and the gear 68 are meshed with each other.

The right end of the rotating shaft 67 is fixedly connected with a knob 66 ​​for facilitating the operator to rotate the rotating shaft 67.

[0035] Working principle: when processing is required, the workpiece needs to be placed on the top of the fixed plate 4 first, and then the motor 2 can be started to drive the double-headed threaded rod 3 to rotate. The rotation of the double-headed threaded rod 3 will drive the moving block 64 to move inward to clamp the workpiece, and then the pull rod 611 can be pulled to drive the fixed block 613 to move forward to disengage from the fixed groove 69, and then the knob 66 ​​can be rotated to drive the rotating shaft 67 and the gear 68 to rotate. When the gear 68 rotates, it will drive the rack 65 and the side clamping block 63 to move inward to fix the two sides of the workpiece. At this time, the pull rod 611 can be released, and the fixing spring 614 will push the fixing block 613 backward to make it re-enter the inside of the fixing groove 69 to re-fix the rotating shaft 67.

[0036] When it is necessary to process other sides of the workpiece, the lever 51 can be pushed to the right to drive the limit block 54 to move to the right and disengage from the inside of the limit groove 53. Then the knob 66 ​​can be directly rotated to drive the fixing ring 610 and the rotating block 52 to rotate. The rotation of the rotating block 52 will drive the clamping plate 61 to rotate, thereby driving the workpiece to rotate. When the workpiece is rotated to a suitable position, the lever 51 can be released, and the limit spring 55 will push the limit block 54 to move to the left and re-engage it in the inside of the limit groove 53, thereby re-fixing the rotating block 52. At this time, the position of the workpiece will also be re-fixed.
