[0007] Preferably, a limiting component is provided on the front side of the column. The limiting component includes two fixed plates fixedly connected to the front side of the column. A threaded rod is rotatably connected through each of the two fixed plates. A knob is fixedly connected to the opposite side of each of the two threaded rods. A threaded sleeve is threadedly connected to each of the two threaded rods. A movable plate is fixedly connected to the adjacent side of each of the two threaded sleeves. Multiple connecting rods are fixedly connected to the adjacent side of each of the two movable plates. An arc-shaped stop is fixedly connected to the side of each of the multiple connecting rods away from the movable plate.

[0008] Preferably, the left and right sides of the two movable plates are slidably connected to the adjacent sides of the two stop mounting plates.

[0009] Preferably, a buffer pad is fixedly connected to the upper end of each of the two stop mounting plates, and both buffer pads are made of rubber.

[0010] Preferably, the top view of the stop plate is convex.

[0011] Preferably, the movable plate, multiple connecting rods, and arc-shaped stop are integrally formed.

[0012] Compared with existing technologies, the advantages of this device are:

[0013] 1. Compared with the existing technology, by setting nuts and limiting components, when installing the stop frame, the stop frame is initially fixed by the nuts. Then, multiple arc-shaped blocks are moved to the front of the nuts to limit the nuts and prevent the stop frame from becoming loose from the column. At the same time, it can also detect whether the nuts are installed in place.

[0014] 2. Compared with the existing technology, by setting the buffer pad, when the stop pin is not retracted and moves upward, the stop plate will first rotate upward and then rotate back to fall on the buffer pad, thereby reducing the generation of noise and avoiding damage to the stop frame caused by impact, thus improving the overall service life of the stop frame.
