[0013] Further, a threaded hole is provided in the interior of each sleeve. Each sleeve is threadedly connected with a bolt through the threaded hole.

[0014] Through the above solution, the bolt can be installed through the threaded hole, and the bolt is resisted against the winding roller to position the sleeve, increasing the stability of the sleeve.

[0015] Further, a limiting plate is fixedly connected to the outer circumferential surface of the winding roller. An empty groove is provided in the interior of each sleeve. Each sleeve is slidably connected to the outer surface of the limiting plate through the empty groove provided in the interior.

[0016] Through the above solution, the sleeve is prompted to always move horizontally, avoiding rotation of the sleeve, and increasing the stability of the sleeve.

[0017] Further, an empty groove is provided in the interior of the head sleeve. The head sleeve is slidably connected to the outer surface of the limiting plate through the empty groove provided in the interior.
