[0031] A first motor 24 is fixedly mounted on the top of the support plate 23 . The output end of the first motor 24 movably passes through the interior of the support plate 23 and is fixedly connected to the left front gear 25 .

[0032] A second hydraulic rod 34 is fixedly mounted on the top of the compression rod 31, and the output end of the second hydraulic rod 34 is fixedly mounted on the top of the extension rod 32 through the side plate, and the extension rod 32 is flush with the bottom of the compression rod 31.

The workbench 1 is made of stainless steel.

[0033] In this embodiment, the gear 25 can be driven to rotate by starting the first motor 24. Through the linkage between the gears 25, the rotation directions of adjacent gears 25 are opposite, so that the adjacent pressure rods 31 can be driven to move closer or farther away synchronously. The distance between the extension rod 32 and the pressure rod 31 can be adjusted by starting the second hydraulic rod 34, so that the overall length of the extension rod 32 and the pressure rod 31 can be adjusted, and the outermost side of the extension rod 32 can be made to correspond to the four corners of the corresponding plywood by adjusting the angle of the pressure rod 31.

[0036] In this embodiment, when fixing the plywood, the plywood is placed on the workbench 1. After placement, the bidirectional motor is started, and the bidirectional motor drives the screw rods 54 on both sides to rotate synchronously in the same direction. The threads on the screw rods 54 on both sides rotate in opposite directions. The rotation of the screw rods 54 can realize the synchronous reverse movement of the two sliders 53 on the outer side thereof. The synchronous reverse movement of the sliders 53 can drive the splints 51 to move synchronously in the opposite direction. The plywood can be fixed by clamping the splints 51 on both sides of the plywood respectively. After fixation, the plywood can be located at the center of the left and right sides, making it more convenient to squeeze.

The threads on the screw rods 54 on both sides rotate in opposite directions. The rotation of the screw rods 54 can realize the synchronous reverse movement of the two sliders 53 on the outer side, and the synchronous reverse movement of the sliders 53 can drive the clamping plates 51 to move synchronously in the opposite direction. The plywood can be fixed by clamping the clamping plates 51 on both sides of the plywood respectively, and the plywood can be located at the center of the left and right sides after being fixed, making it more convenient to squeeze. The gear 25 can be driven to rotate by starting the first motor 24. Through the linkage between the gears 25, the rotation directions of the adjacent gears 25 are opposite, so that the adjacent pressure rods 31 can be driven to move closer or farther away synchronously. The extension rod 32 and the pressure rod can be adjusted by starting the second hydraulic rod 34. The distance between the two ends of the workbench 1 is set to 31, so that the overall length of the extension rod 32 and the pressure rod 31 can be adjusted, and the outermost side of the extension rod 32 can be matched with the four corners of the corresponding plywood by adjusting the angle of the pressure rod 31. The electromagnet 44 is driven downward by starting the third hydraulic rod 41, and is moved to the top of the workbench 1 by the electromagnet 44, and the electromagnet 44 is started, and the electromagnet 44 is adsorbed on the workbench 1, thereby completing the fixation of the top plate 42; by adjusting the angle of the pressure rod 31 and the length of the extension rod 32, and fixing the top plate 42 by the electromagnet 44, after adjustment and fixation, the plywood is squeezed from the center and the four corners by starting the first hydraulic rod 22 and the fourth hydraulic rod 43 respectively, and the four corners and the center are squeezed by the pressure rod 31 and the extension rod 32 during extrusion, thereby greatly increasing the extrusion area and greatly reducing the probability of uneven extrusion.
