When the two connecting shafts 301 rotate clockwise or counterclockwise, they drive the two sets of gears 302 to rotate clockwise or counterclockwise. Since the two sets of gears 302 are meshed and connected with one end of the two rack plates 9, the rack plates 9 are fixed on the processing table 1 through the connecting strips 102, and the rack plates 9 remain different, and when the two sets of gears 302 rotate clockwise or counterclockwise, they will move relative to or in the opposite direction on the rack plate 9. When the two sets of gears 302 move relative to or in the opposite direction, they will drive the connecting shaft 301 and the placement rod 3 rotatably mounted with the connecting shaft 301 to move relative to the processing table 1. Or opposite movement, it is convenient to adjust the distance between the two placement rods 3, which is conducive to adapting cover bodies 2 of different sizes, and it is convenient to place the two ends of the cover body 2 on the two placement rods 3.

Since the two electric push rods 7 and multiple limiting tubes 6 are fixed on the top of the U-shaped frame 4, it is convenient to drive the two electric push rods 7 and multiple limiting tubes 6 to move synchronously when the two U-shaped frames 4 move relative to each other or move oppositely. The output ends of the two electric push rods 7 are fixed to the column lower pressure plate 8, and there is a sliding rod 601 between the lower pressure plate 8 and the limiting tube 6. The staff controls the electric push rod 7 to work through the controller 10, drives the lower pressure plate 8 to move in the direction of the placement rod 3, clamps and fixes the cover body 2 on the placement rod 3, and drives the sliding rod 601 to slide in the limiting tube 6 when the lower pressure plate 8 moves downward, so as to improve the stability of the lower pressure plate 8 when it moves downward.

Multiple anti-slip feet 105 are fixedly installed at one end of the processing table 1 away from the two U-shaped frames 4, and a controller 10 is fixedly installed at one end of the processing table 1, and the controller 10 is electrically connected to the two motors 5 and the two electric push rods 7 respectively.

[0042] In this embodiment, when in use, the two U-shaped frames 4 drive the multiple connecting rods 104 at one end of the two U-shaped frames 4 to move relative to or oppositely. The multiple connecting rods 104 drive the rotating wheels 103 at one end of the multiple connecting rods 104 to move relative to or oppositely in the two slide grooves 101. Since the rotating wheels 103 and the connecting rods 104 are rotatably installed, when the rotating wheels 103 move in the slide grooves 101, the friction can be reduced by reducing the contact area with the slide grooves 101 and the rotation of the rotating wheels 103.

The staff controls the two motors 5 and the two electric push rods 7 to work through the controller 10, and controls the output ends of the two motors 5 to drive the two connecting shafts 301 to rotate clockwise or counterclockwise. When the two connecting shafts 301 rotate clockwise or counterclockwise, they drive the two sets of gears 302 to rotate clockwise or counterclockwise. Since the two sets of gears 302 are meshed and connected with one end of the two rack plates 9, the rack plates 9 are fixed on the processing table 1 through the connecting strips 102, and the rack plates 9 remain different, the two sets of gears 302 rotate clockwise or counterclockwise. When the two sets of gears 302 move relative to or oppositely, they will drive the connecting shaft 301 and the placement rod 3 rotatably mounted with the connecting shaft 301 to move relative to or oppositely on the processing table 1, which is convenient for adjusting the distance between the two placement rods 3, which is conducive to the application of cover bodies 2 of different sizes, and convenient for placing the two ends of the cover body 2 on the two placement rods 3. When the two connecting shafts 301 move relative to or oppositely, they will drive the two U-shaped frames 4 to move relative to or oppositely. Since the two electric push rods 7 and the plurality of limit tubes 6 are fixed on the top of the U-shaped frame 4, it is convenient for the two U-shaped frames 4 to drive the two relative to or oppositely when they move relative to or oppositely. The electric push rod 7 and the plurality of limit tubes 6 move synchronously, the output ends of the two electric push rods 7 are fixed to the lower pressing plate 8, and there is a sliding rod 601 between the lower pressing plate 8 and the limit tube 6. The staff controls the electric push rod 7 to work through the controller 10, drives the lower pressing plate 8 to move in the direction of the placement rod 3, clamps and fixes the cover plate body 2 on the placement rod 3, and drives the sliding rod 601 to slide in the limit tube 6 when the lower pressing plate 8 moves downward, so as to improve the stability of the lower pressing plate 8 when it moves downward. When in use, the two U-shaped frames 4 drive the plurality of connecting rods 104 at one end of the two U-shaped frames 4 to move relative to or oppositely, and the plurality of connecting rods 104 move relative to or oppositely. When the processing table 1 is moved, the rotating wheels 103 at one end of the multiple connecting rods 104 are driven to perform relative or opposite movements in the two slide grooves 101. Since the rotating wheels 103 and the connecting rods 104 are rotatably installed, when the rotating wheels 103 move in the slide grooves 101, the friction can be reduced by reducing the contact area with the slide grooves 101 and the rotation of the rotating wheels 103. A plurality of anti-skid feet 105 are fixed at one end of the processing table 1. The anti-skid feet 105 are in contact with other objects, so as to improve the stability of the processing table 1 when it is placed.
