Through the use of the fixing component, it is convenient to fix connector 18 and connector 2 19. Conversely, it is also convenient to unlock connector 18 and connector 2 19, thereby facilitating the adjustment of the angle of the sleeve 10. The operation is simple and convenient, and the speed of angle adjustment of the sleeve 10 is improved.

[0026] In the present invention, the fixing assembly includes a cylinder 12 slidably arranged in a circular cavity 15 and a circular plate 11 fixed to the top of the cylinder 12. A tension spring 14 is provided between the bottom of the cylinder 12 and the circular cavity 15.
