A worm gear is sleeved on the outer wall of the nut cylinder. One side of the worm gear is connected with a worm through meshing. An installation frame is fixed on the end plate. A rotating column is rotatably embedded on the installation frame. One end of the rotating column is connected to the surface of the worm, and an anti-slip sleeve is sleeved on the outer wall of the other end of the rotating column.

[0006] Preferably, a limiting frame is arranged on the bottom side of the nut cylinder, and the limiting frame is fixed on the surface of the end plate.

[0007] Preferably, there are four limiting frames, and the four limiting frames are arranged in a circular array about the central axis of the nut cylinder.

[0008] Preferably, the longitudinal section of the limiting frame is an L-shaped structure, and the longitudinal section of the nut cylinder is a convex-shaped structure.

[0009] Preferably, a first ball groove is formed on the surface of the limiting frame, and a first ball is embedded in the first ball groove.

[0010] Preferably, a support seat is sleeved on the outer wall of one end of the worm, and the support seat is fixed on the surface of the end plate.

[0011] Preferably, a second ball groove is formed in the inner wall of the support seat, and a second ball is embedded in the second ball groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] (1) Through the designed nut cylinder, worm gear, worm, mounting bracket and rotating column, the nut cylinder equipped with the worm gear is arranged on the end plate, the worm is connected to the mounting bracket through the rotating column. When the end of the U-shaped screw rod is placed at one end of the two nut cylinders, rotate the rotating column, the rotating column drives the worm to rotate, the worm meshes and drives with the two worm gears at the same time, driving the two worm gears to rotate, and then driving the two nut cylinders to rotate simultaneously and threadedly assemble with both ends of the U-shaped screw rod, making the assembly of the present utility model time-saving, labor-saving, convenient and fast. Through the designed limit frame, the limit frame is arranged at the end of the nut cylinder to axially limit the nut cylinder, avoiding the shaking of the nut cylinder and affecting the transmission effect of the worm gear and worm. Through the designed first ball, it plays a lubricating role, avoiding the generation of frictional resistance and wear between the end face of the limit frame and the surface of the nut cylinder. Through the designed support seat, the support seat is arranged at the end of the worm to support the suspended end of the worm, avoiding the skew of the suspended end of the worm.
