However, the patent has the following defects: when the fixing frame changes its position on the vertical steel bar, it is necessary to cooperate with the double-ear fastening bolt to realize the unlocking and locking process, and the adjustment process is relatively cumbersome, and when the double-ear fastening bolt is loose, it is easy to cause the fixing frame to slide downward along the vertical steel bar, resulting in inaccurate height positioning of the wire rope.

[0004] In view of this, how to change the current situation of complicated adjustment process and poor stability of the fixing frame has become a technical problem that technical personnel in this field need to solve urgently. Utility Model Content
