[0045] The self-tightening movable module 42 includes a second movable frame 421, an elastic spring 422, and a one-way locking structure. The second movable frame 421 is in limited sliding connection with the adjustment guide rail 412. A plurality of elastic springs 422 are evenly spaced between the second movable frame 421 and the first movable frame 413. One end of the elastic spring 422 is fixedly connected to the second movable frame 421, and the other end of the elastic spring 422 is fixedly connected to the first movable frame 413. The one-way locking structure is installed on the first movable frame 413 and the second movable frame 421.

[0046] The one-way locking structure includes a locking plate 423, a locking tooth 424, a rotating block 425 and a fixed stopper 426. The locking plate 423 is fixedly mounted on the first movable frame 413, and a plurality of locking teeth 424 are evenly and evenly fixedly mounted on the first movable frame 413; a guide ramp is provided on one side of the locking tooth 424, and a slot is formed between the two locking teeth 424; one end of the rotating block 425 is hinged to the second movable frame 421, and a torsion spring is sleeved on the hinge axis of the rotating block 425 and the second movable frame 421, and the two elastic legs of the torsion spring abut against the rotating block 425 and the second movable frame 421 respectively; the rotating block 425 slides in contact with the guide ramp of the locking tooth 424, and the rotating block 425 is engaged with the slot formed by the two locking teeth 424; a fixed stopper 426 is fixedly mounted on the second movable frame 421; the fixed stopper 426 abuts against one side of the rotating block 425;
