[0025] Working principle:

[0026] Preparation stage

[0027] By putting the connecting ring 304 on the first connecting member 302 and screwing the fixing screw 303 through the first connecting member 302 and the connecting ring 304, the connecting ring 304 and the first connecting member 302 are fixed, and at the same time, the end of the strap 403 is inserted out of the connecting head 305, and the teeth 402 on the strap 403 contact the pawl 401 in the forward direction, and the strap 403 can be easily pulled out from the connecting head 305.

[0028] Installation phase

[0029] The installer manually pushes the push button 8, which drives the first connecting member 302 and the block 301 on its surface to move. The block 301 pushes the first connecting nut 2 to rotate, so that the interior of the first connecting nut 2 is threadedly installed with the installation position. At this time, the strap 403 is manually pulled, and the strap 403 drives the teeth 402 to move on the connecting head 305 until the first rubber sealing strip 6 on the inner wall of the strap 403 enters the transverse groove 5 for sealing, and the second rubber sealing strip 11 on the inner wall of the strap 403 is also fitted and sealed in the same way. At the same time, the teeth 402 inside the strap 403 will also enter the tooth groove 404 on the outer wall of the first connecting nut 2, so that the strap 403 is tightly fitted with the first connecting nut 2. After the teeth 402 on the strap 403 reversely contact the pawl 401 inside the connecting head 305, the pawl 401 will resist the inward tensile force of the teeth 402 on the internal strap 403, ensuring that the strap 403 will not loosen on the first connecting nut 2 at will.
