[0034] On the basis of the above embodiments, some other embodiments of the present application may be further increased or limited by one or more of the following combinations on the basis of the above specific embodiments.

[0035] The fixing assembly 20 includes a first bearing plate 201, a first reinforcing plate 202, a first connecting plate 203 and a first curved plate 204.

[0038] The second arc plate 304 and the second connecting plate 303 form a cavity between the second supporting plate 301 and the second reinforcing plate 302 . The second connecting plate 303 and the second arc plate 304 are provided with a second waist-shaped hole, and the other end of the connecting component 40 passes through the second waist-shaped hole.

[0039] The two cavities formed above, one of which is used to install one end of the connecting component 40, and the other is used for the other end of the connecting component 40 to pass through. The above two cavities are used to install the connecting component 40, and the connecting component 40 drives the active end of the steel belt 10 to tighten.

[0040] The connecting component 40 includes a connecting rod 401, a connecting boss 402 and a rotating sleeve 403. The connecting boss 402 is arranged at one end of the connecting rod 401, and the connecting boss 402 is located in a cavity formed between the first supporting plate 201 and the first reinforcing plate 202.

[0041] The connecting rod 401 passes through the cavity formed between the second bearing plate 301 and the second reinforcing plate 302, and the rotating sleeve 403 is horizontally arranged in the cavity. When the connecting rod 401 is controlled by the control component 50, it will drive the rotating sleeve 403 to move, and the rotating sleeve 403 will drive the movable component 30 to move in the cavity, thereby driving the movable belt of the steel belt 10 to tighten toward the fixed end.

[0045] When the steel belt 10 is tightened, the steel belt 10 will compress the compensation spring sheet 601. Since the compensation spring sheet 601 has elastic force, it will cause the compensation spring sheet 601 to deform, which will give the steel belt 10 a corresponding reaction force, thereby giving the steel belt 10 a certain compensation force, further increasing the connection stability of the steel belt 10 after the steel belt 10 is tightened. A clamping claw is provided on the mounting plate, which is clamped on the steel belt 10 by the clamping claw, so as to facilitate the later disassembly. Similarly, the compensation spring sheet 601 is also clamped in the cavity by the clamping claw.
