[0008] A further improvement is that a cylindrical handle is arranged on the outer side of the adjusting nut to facilitate the hand to twist the adjusting nut, and an anti-slip portion is arranged on the cylindrical handle.

[0009] A further improvement is that the anti-slip portion is a plurality of anti-slip convex strips arranged on the outer side of the cylindrical handle.

[0010] A further improvement is that the friction reducing member comprises a placement groove opened on the side end surface of each of the position limiting anti-collision plates, and a rotating wheel rotatably arranged on each of the position limiting anti-collision plates and located in the placement groove.
