Then, the angle of the clamping blocks is limited by the limiting assembly, so that the clamping blocks on the two sides of the steel support can be clamped in the mounting brackets on the two support plates, and the steel support can be smoothly installed.

[0014] By adopting the above technical scheme, the first spring is arranged, the first spring forces the control rod to slide so that the second limiting teeth are clamped on the first limiting teeth, thereby improving the stability of the limiting.

[0015] Optionally, the steel support is provided with a limiting frame for limiting the control rod, the limiting frame is U-shaped, both ends of the limiting frame are hingedly connected to the steel support, and the U-shaped opening of the limiting frame faces the control rod.

[0016] By adopting the above technical scheme, the control rod can be limited by rotating the limiting frame, the possibility of the clamping plate separating from the clamping of the first rotating plate is reduced, and the limiting frame needs to be removed from the control rod before the control rod is controlled, thereby reducing the possibility of misoperation of the construction personnel.

[0017] Optionally, the longitudinal section at both ends of the limiting frame is provided with a connecting rod, the connecting rod is connected to the limiting frame along the length direction of the longitudinal section of the limiting frame, and the limiting frame is provided with a second spring for forcing the limiting frame and the connecting rod to slide in the direction of approaching each other.

[0019] Optionally, one end of the operating rod is semispherical, and the inner side surface of the limiting frame is provided with an arc-shaped groove for clamping the operating rod.

[0020] By adopting the above technical scheme, the arc-shaped groove is arranged on the inner side surface of the limiting frame, and the operating rod is clamped in the arc-shaped groove, so that the stability of the limiting is improved.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. When the supporting plates on both sides have a certain inclination angle, the clamping blocks can be rotated relative to the steel support to adapt to the corresponding mounting bracket, and then the angle of the clamping blocks is limited by the limiting assembly, so that the clamping blocks on both sides of the steel support can be clamped in the mounting brackets on the supporting plates on both sides, and the steel support can be smoothly installed.

[0023] 2. The operating rod can be limited by rotating the limiting frame, which reduces the possibility of the clamping plate separating from the first rotating plate, and the limiting frame needs to be removed from the operating rod before operating the operating rod, thereby reducing the possibility of misoperation of the construction personnel.
