[0021] In this embodiment: the multiple clamping blocks 3 on the lower connecting ring 2 correspond to the multiple clamping grooves 4 on the upper connecting ring 1, so that the connection can be made by rotating clamping, and the threaded outer tube 6 on the fixed inner tube 5 can clamp the connected shrink tube body 7, so that the connection between the shrink sleeves can be more convenient, and the two parts are connected together by clamping, and the extrusion force and the sealing ring 9 are used to ensure the sealing of the connection.

[0022] Specifically, a cold shrink tube body 7 is slidably embedded between the threaded outer tube 6 and the fixed inner tube 5 .

[0023] In this embodiment, the elasticity of the cold shrink tube body 7 can be used to cover the fixed inner tube 5, and the extrusion force generated by the threaded outer tube 6 is used to fix it.

[0024] Specifically, a plurality of anti-slip strips 8 are provided on the outer wall of the threaded outer tube 6 at equal distances along the circumferential surface.

[0025] In this embodiment, the friction force of the outer wall of the threaded outer tube 6 can be increased by using a plurality of anti-slip strips 8, thereby facilitating the rotation of the threaded outer tube 6.

[0026] Specifically, a groove ring is provided between the upper connecting ring 1 and the lower connecting ring 2 and a sealing ring 9 is embedded therein.

[0027] In this embodiment, the sealing ring 9 can increase the sealing performance between the upper connecting ring 1 and the lower connecting ring 2 when the upper connecting ring 1 and the lower connecting ring 2 are squeezed.
