The screw sleeve 443 is located on the side facing the center of the mounting plate 42, and an annular cover plate is arranged at the opening of the counter bore 441 and is used for preventing the screw sleeve 443 and the spring 442 from falling off. The screw sleeve 443 is movably arranged along the axial direction of the counter bore 441, and the circumferential position of the screw sleeve 443 relative to the counter bore 441 is kept fixed. Specifically, a strip-shaped groove 444 is formed in the side wall of the counter bore 441 in the axial direction, a protruding strip 445 is arranged on the outer wall of the thread sleeve 443 in the axial direction, the protruding strip 445 is slidably arranged in the strip-shaped groove 444, the thread sleeve 443 is sequentially ensured to be fixed relative to the circumferential position of the counter bore 441, and the thread sleeve 443 is prevented from rotating. Because of the manufacturing error of the screw rods 43 and the installation accuracy error of the slide block 44 and the push plate 41, and the four screw rods 43 are all driven by the same driving motor 45, the moving distance of the push plate 41 after the four screw rods 43 rotate for the same number of turns is easy to have a certain difference, and part of the reinforcing plate 92 cannot be attached to the supporting rod 91; in order to ensure the overall structural size of the support member, each reinforcing plate 92 is closely attached to the corresponding support rod 91, and the structure of the slider 44 is specially designed; when one of the pushing plates 41 pushes the reinforcing plate 92 to contact with the corresponding supporting rod 91 first during use, and the other reinforcing plates 92 are not in contact with the supporting rod 91, at this time, the driving motor 45 is required to continue to implement the continuous movement of the other reinforcing plates 92. In the process, the reinforcing plate 92 which is firstly contacted with the supporting rod 91 stops moving, the push plate 41 and the slide block 44 which correspond to the reinforcing plate stop moving continuously, and the screw sleeve 443 starts to act in order to adapt to the continuous rotation of the screw rod 43. When the slide block 44 stops, the screw rod 43 continues to rotate, and the thrust generated by the rotation of the screw rod acts on the thread sleeve 443, so that the thread sleeve 443 is subjected to axial thrust, and the circumferential rotation of the thread sleeve 443 is limited, and the thread sleeve can only move along the axis of the counter bore 441. The movement of the screw sleeve 443 will compress the spring 442, and the compression stroke of the spring 442 satisfies the distance that the screw rod 43 drives the screw sleeve 443 to move when rotating, thereby ensuring that other reinforcing plates 92 can be attached to the supporting rod 91. When the reinforcing plate 92 is assembled and welded, the slider 44 is moved toward the middle of the mounting plate 42, the block on the slider 44 is released, and the slider 44 is moved along the axis of the wire sleeve 443 by the spring 442, so that the spring 442 is expanded again.

Preferably, as shown in fig. 3 and 4, connecting columns 14 are vertically arranged on the top surface of the workbench 1 and between adjacent output rails 12, and the upper ends of the connecting columns 14 penetrate through the mounting plate 42, so as to realize a detachable connection structure of the pushing component 4. Specifically, the connecting column 14 can be provided with external threads, the mounting plate 42 is locked and fixed through a nut, and a bolt can be penetrated through the connecting column 14, so that the mounting plate 42 can be positioned and mounted, and the mounting plate 42 can be conveniently detached.

The foregoing is only a preferred embodiment of the present invention and is not intended to be exhaustive or to limit the invention. It will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention.
