The bidirectional screw 4 can be driven to rotate by driving the motor 3, and the bidirectional screw 4 can be used to drive the two sliders 5 to approach each other, thereby driving the two connecting blocks 8 to approach each other, and the two top rods 11 and the two top plates 12 can be driven to approach each other through the two connecting blocks 8. At this time, the two top plates 12 can be respectively pressed on both sides of the engineering machinery parts, thereby clamping the engineering machinery parts.

[0033] Reference Figure 1-2 A slide groove 9 is provided in the middle of the boss 2, and the slide groove 9 is set to an inverted U shape. The other end of the bidirectional screw 4 is rotatably connected to the middle of one side wall of the slide groove 9, and the two side clamping plates 6 are respectively located on both sides of the slide groove 9, and the slider 5 is slidably connected to the inner wall of the slide groove 9. A clamping groove 10 is provided on the bottom surface of the connecting plate 7, and the clamping groove 10 is set to an inverted U shape, and the connecting plate 7 is slidably connected to the top surface of the boss 2 through the clamping groove 10. The inclined surfaces on both sides of the top of the boss 2 can be used to guide metal debris to fall, so that it falls on the bottom surface of the bottom plate 1 and is located on both sides of the boss 2.

[0036] Working principle: when in use, first place the engineering machinery parts to be processed in the middle of the boss 2, and then drive the bidirectional screw 4 to rotate through the driving motor 3. The rotation of the bidirectional screw 4 can drive the two sliders 5 to approach each other. At this time, the cooperation of the slider 5, the clamping plate 6 and the connecting plate 7 can be used to drive the two connecting blocks 8 to approach each other. The two connecting blocks 8 can respectively drive the two top rods 11 and the two top plates 12 to approach each other. At this time, the two top plates 12 can be respectively pressed on both sides of the engineering machinery parts, so as to clamp the engineering machinery parts. When the engineering machinery parts are clamped, they can be processed at this time, and the metal chips generated during the processing will fall on the top surface of the boss 2. The inclined surfaces on both sides of the top of the boss 2 can be used to guide the metal chips to fall, so that they fall on the bottom surface of the bottom plate 1 and are on the convex surface. On both sides of the platform 2, by arranging the bidirectional screw 4 and the slider 5 in the middle of the boss 2, it is possible to prevent debris generated during the processing from falling on the bidirectional screw 4, thereby preventing the bidirectional screw 4 from getting stuck, and by driving the telescopic rods 13 on both sides of the connecting block 8 to extend out of the output end, the two clamps 14 can be pushed out at this time to rotate along the two first connecting seats 15 as the center of the circle, and the four clamps 14 can be clamped on the outside of the engineering machinery parts respectively.
