The other end of the clockwork spring 308 is fixedly connected to the positioning frame 306, and the second gear 309 is meshedly connected to the first gear 305.

[0024] The effect achieved by the entire embodiment 1 is that the provided mounting frame 301 can support the rotating rod 302, the positioning frame 306 and the connecting frame, the provided positioning frame 306 can fix the outer end of the spring 308, and when the positioning rod 304 drives one end of the rubber belt 303 to move, the rotating rod 302 drives the first gear 305 to rotate, the first gear 305 drives the second gear 309 to rotate, the second gear 309 drives the connecting rod 307 to rotate, and the connecting rod 307 drives the inner end of the spring 308 to rotate, so that the spring 308 is always in a stressed state, thereby tightening the rubber belt 303, and when the other end of the rubber belt 303 is fixed in position by the positioning rod 304, the rubber belt 303 is in a taut state, so that the fastening is better.

[0025] Embodiment 2, as Figure 1-4 As shown, a fixing frame 310 is provided on the top of the cover body 2, and a slot 311 is provided on the surface of the fixing frame 310, and the positioning rod 304 is engaged with the slot 311, and the connecting rod 307 is rotatably connected to the mounting frame 301 through a bearing, a guide roller 4 is provided on the surface of the cover body 2, and the rubber belt 303 is in contact with the guide roller 4, a bolt 5 is provided on the surface of the cover body 2, and the bolt 5 is threadedly connected to the box body 1, and the cover body 2 and the box body 1 are slidably connected, a buffer spring 6 is provided on the surface of the fixing frame 310, and a butt plate 7 is provided on the other end of the buffer spring 6, and the butt plate 7 is in contact with the fixing frame 310, a through hole 8 is provided on the surface of the rubber belt 303, and a baffle 9 is provided on the surface of the mounting frame 301, a first through hole is provided on the surface of the slot 311 for the rubber belt 303 to pass through, and a second through hole is provided on the surface of the baffle 9 for the rubber belt 303 to pass through, a limiting rod 10 is provided between the fixing frame 310 and the cover body 2, and the butt plate 7 is slidably connected to the limiting plate.

[0026] The effect achieved by the entire embodiment 2 is that the provided slot 311 can clamp the positioning rod 304, the provided guide roller 4 can guide the rubber belt 303 to increase the service life of the rubber belt 303, the provided bolt 5 can fix the cover body 2 on the box body 1, the provided abutment plate 7 can limit the positioning rod 304 to improve the stability of the positioning rod 304, the provided baffle plate 9 can cooperate with the mounting frame 301 and the positioning rod 304 to be stored, the provided first through hole and the second through hole are convenient for the rubber belt 303 to pass through, and the provided limit rod 10 can improve the stability of the abutment plate 7 when it moves.

[0027] The working principle is to clamp the cover body 2 on the top of the box body 1 and fix it with the bolt 5, and then pull the positioning rod 304 outward to move the positioning rod 304 above the abutment plate 7, and push the abutment plate 7 downward. At this time, the positioning rod 304 can be clamped in the clamping groove 311 on the fixing frame 310, and the elastic force of the buffer spring 6 pushes the abutment plate 7 upward so that it can resist the fixing frame 310.
