[0028] Through the above technical scheme, the hydraulic cylinder 6 can be supported by the support frame 7. By starting the hydraulic cylinder 6, the clamping block 9 can be pushed to move. The clamping block 9 relies on the slider 10 to move more stably in the slide groove 11. The clamping block 9 clamps and fixes the workpiece. The outer walls of the clamping block 9 and the fixed block 2 are provided with rubber pads. The rubber pads are provided to prevent the workpiece from being clamped.

[0039] When in use, first start the hydraulic cylinder 6. One end of the hydraulic cylinder 6 pushes the clamping block 9 to move. The clamping block 9 drives the slider 10 to move more stably in the slide groove 11. The clamping block 9 moves to clamp and fix the workpiece. After clamping and fixing, the operator pulls the pressure block 308 upward. The pressure block 308 drives the long rod 307 to move upward. The long rod 307 drives the round block 306 to move upward. The round block 306 drives the circular plate 304 to move upward. The circular plate 304 moves upward to shrink the fixing spring 303. The pressure block 308 moves upward to exceed the workpiece. The operator rotates The pressing block 308 drives the long rod 307 to rotate, and the long rod 307 drives the round block 306 to rotate in the circular groove 301, so that one end of the pressing block 308 rotates to the top of the workpiece, and the pressing block 308 is released. The fixed spring 303 rebounds and drives the circular plate 304 to move downward. The circular plate 304 drives the round block 306 to move downward, and the round block 306 drives the long rod 307 to move downward. The long rod 307 drives the pressing block 308 to move downward. The pressing block 308 presses the workpiece tightly through the elastic force of the fixed spring 303 to prevent the workpiece that is not firmly clamped from being clamped during the processing. The waste chips generated by the workpiece processing fall into the collection box 403 through the through slot 401, and the collection box 403 collects the waste chips. When the waste chips are collected and the collection box 403 needs to be pulled out of the slot 402, the clamping block 407 is driven to leave the clamping slot 404 by pulling the pull rod handle 409, and the operator pulls the collection box 403 out of the slot 402. The operator handles the waste chips in the collection box 403. When installing the collection box 403, the pull rod handle 409 is pulled out. 09 drives the card block 407 to move, and the movement of the card block 407 drives the installation spring 408 to contract. The operator inserts the collection box 403 into the slot 402 and installs it, loosens the pull rod handle 409, and the installation spring 408 rebounds and drives the card block 407 to move in the long groove 406. One end of the card block 407 extends into the card slot 404 of the collection box 403 and engages, so as to fix the collection box 403. This completes all the work.
