[0007] A second hook is fixed at the top of the fixed clamp, the openings of the first hook and the second hook are opposite, and after the distance is adjusted, they are hung on the lower flanges of the H-shaped steel beam on both sides respectively.

[0008] The lifting ring sleeve pipe comprises a sleeve pipe and a lifting ring, the sleeve pipe is welded with the lifting ring, the sleeve pipe is sleeved on the main horizontal rod, and the lifting ring suspends the safety belt.

[0009] The spring is in a compressed state.

[0010] The technical effects and advantages of the utility model are as follows:

[0011] The safety belt fixing device is installed on the lower flange of the H-shaped steel beam, is free from welding, is convenient to assemble and disassemble, enables the construction personnel to conveniently move and improve construction efficiency, provides a stable connecting point, and solves the problems of the traditional safety belt needing welding to affect the quality of the steel structure finished product and being only able to be tied on an operating frame during construction, and does not meet the requirement of high hanging and low use.

[0012] The safety hazard problem of falling from a high place is solved, the protection of the steel structure finished product is improved, and the construction efficiency is improved. BRIEF DESCRIPTION OF DRAWINGS
