[0034] Referring to Figure 1 and Figure 5A clamping assembly is provided on the top of the moving platform 15, and the clamping assembly is used to conveniently fix parts of different sizes. The clamping assembly includes an electric push rod 16, and the electric push rod 16 is fixedly connected to the inside of the moving platform 15. A trapezoidal block 20 is fixedly connected to the top of the electric push rod 16, and wedge blocks 21 are fixedly connected to the left and right sides of the trapezoidal block 20. A movable block 22 is slidably connected to the left and right sides of the trapezoidal block 20. The tops of the two movable blocks 22 are fixedly connected to clamp plates 24, and the clamp plates 24 are used to fix the processed parts.

The hydraulic rod 13 is used to control the movement of the moving platform 15. After the cover plate 2 is opened, the moving platform 15 can be raised.

[0036] Working principle: first, pull the connecting rod 6 through the pull ring 5 to move, and the connecting rod 6 drives the baffle 8 to move. After the plug block 9 fixedly connected to the baffle 8 slides out from the inside of the side panel 3, the side panel 3 can be rotated, and then the lever 10 is moved to make the lever 10 drive the plug rod 11 to squeeze the spring 2 12. After the side panel 3 is rotated to the same horizontal plane as the movable workbench 1, the lever 10 can be released, and the spring 2 12 is reset to generate a thrust to push the plug rod 11, so that the plug rod 11 is inserted into the inside of the side panel 3, thereby fixing the side panel 3 and completing the deployment.

[0037] Subsequently, open the cover plate 2 and start the hydraulic rod 13. The hydraulic rod 13 drives the moving platform 15 to move upward. After the moving platform 15 moves to the same plane as the movable workbench 1, work can begin. Place the workpiece between the two clamping plates 24, and then start the electric push rod 16. The electric push rod 16 drives the trapezoidal block 20 to move downward.

The lever 10 drives the plug 11 to move. After the plug 11 slides out from the inside of the side plate 3, the side plate 3 can be rotated downward. Then pull the pull ring 5. The connecting rod 6 also drives the baffle 8 to move and compresses the first spring 7. After the side plate 3 moves to fit the side of the movable workbench 1, release the connecting rod 6. The first spring 7 returns to generate a thrust to push the baffle 8, and then the plug 9 moves correspondingly. The plug 9 inserts into the inside of the side plate 3, thereby limiting the side plate 3 and completing the folding.
