[0022] The locking device 5 includes fixed outer cylinder 12 and tightening assembly 13, fixed outer cylinder 12 is fixedly installed on rubber sleeve 2, the inside of fixed outer cylinder 12 is provided with cavity, and tightening assembly 13 is arranged in fixed outer cylinder 12, the lateral wall of the fixed outer cylinder 12 is equipped with a pair of symmetrical second strip-shaped through-hole 20, two second strip-shaped through-hole 20 are communicated with first strip-shaped through-hole 16 by cavity, one end of fixed outer cylinder 12 is equipped with first through-hole 21, a plurality of teeth 22 are fixedly connected in the first through-hole 21, and the first through-hole 21 is fixedly communicated with inner cavity, the other end of fixed outer cylinder 12 is equipped with second through-hole 23, and the second through-hole 23 is fixedly communicated with inner cavity.

[0023] The tightening assembly 13 includes a limiting disc 14, a spring 15, a tightening drum 24 and a knob 17. The tightening assembly 13 can rotate in the fixed outer cylinder 12 to tighten the soft band 6. The tightening drum 24 penetrates through both ends of the fixed outer cylinder 12 and is rotationally connected with the fixed outer cylinder 12. The soft band 6 penetrates through the two second strip-shaped through holes 20 and the first strip-shaped through hole 16. The limiting disc 14 is fixedly installed at one end of the tightening drum 24. The limiting disc 14 is used to limit the spring 15 and the tightening drum 24 from being pulled out of the fixed outer cylinder 12. The knob 17 is fixedly installed at the other end of the tightening drum 24. The knob 17 can be rotated or pulled out.
