The connecting plate is movably sleeved on the surface of the threaded tube and can move synchronously with the limiting tube, thereby increasing the overall strength of the handle mechanism. The anti-slip sleeve can increase the friction of the grip surface, providing a better grip and anti-slip effect. BRIEF DESCRIPTION OF THE DRAWINGS
