[0002] A hose clamp is an accessory used to connect flexible and rigid pipes. It connects pipes by clamping the joint. As pipes lose elasticity with age, the clamping performance of the hose clamp decreases, which can easily lead to water or oil leaks. Therefore, a clamping force compensation structure is needed to continuously compensate for the clamping force of the hose clamp.

[0003] Among them, a search revealed Chinese patent CN217583595U, which discloses a clamping force compensation type anti-loosening hose clamp. The above patent uses a water-absorbing and expanding resin structure to achieve the clamping force compensation function during the use of the hose clamp. However, since the locking screw on the hose clamp is exposed to the outside, it is easy for people to touch it, which makes the connection of the hose clamp easy to loosen. Therefore, in order to advance the industry's technology, better realize the hose clamp's fastening function, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the protective structure and application method of the hose clamp in the prior art.
