The invention has the beneficial effects that: by fixing fastening mechanisms in the fixed heads, the fixing portions penetrate into the notches in the fixed heads when using, the fixing portions are pressed to push the springs to move, and the compressed springs are reset after the fixing portions penetrate into the notches to push movable blocks to move, so that the notches formed in the two movable blocks clamp the fixing portions, thereby increasing the fixing stability of the handle; the surface of the handle is fixed with an anti-slip pad, one end of the non-slip pad is connected with a Velcro rough surface, and the other end is stitched with a Velcro poke surface,
