[0011] A buffer component is installed in the anti-slipping fixing mechanism, and is used to improve the protection of the connection between the anti-slipping fixing mechanism and the steel bars.

[0012] Furthermore, the rotating part includes a baffle, a limiting shaft, a first threaded barrel and a second threaded barrel.

In the steel bar connection, the first sleeve can be connected to a steel bar end through the second threaded tube, and the second sleeve can be connected to the steel bar end through the first threaded tube, thereby realizing the separate connection of the steel bar ends.

[0014] Furthermore, a limiting ring is fixedly installed on the top side surface of the baffle, and the limiting ring is rotatably connected to a rotating groove opened at the bottom end of the second sleeve.

[0023] Furthermore, there are a plurality of clamping blocks, and the clamping blocks are evenly distributed in a circular shape on the inner wall of the fixed clamping plate.

[0024] In the present technical solution, the fixed clamping plate drives the clamping block arranged on the side surface to fit with the surface of the steel bar. In the process of accidental detachment of the steel bar, the clamping block drives the fixedly installed buffer slider to slide along the buffer slide rod. The buffer spring on one side is stretched and the buffer spring on the other side is squeezed, so that the sliding steel bar drives the clamping block to be dislocated. Under the action of the buffer spring, the steel bar can be restored to its original position later, which is convenient for use.
