When the connecting shaft 61 rotates, it drives the second fixing plate 62 to rotate. The second fixing plate 62 rotates to fix the wire rope 4.

[0025] The working principle of the present invention is as follows: when installing the steel wire rope 4, in order to facilitate the installation of the steel wire rope 4, the steel wire rope 4 is installed on the fixed pulley 3 when the connecting plate 2 is not connected to the housing 1. After installation, the mounting block 21 on the connecting plate 2 is inserted into the groove 13, and the bolt 12 is rotated so that the bolt 12 penetrates into the mounting block 21 to lock it; when it is necessary to fix the steel wire rope 4, a wrench is inserted into the adjustment hole 15, and the threaded rod 52 with an inner hexagon is rotated. The threaded rod 52 moves to the left, driving the first fixing plate 51 to move to the left, thereby fixing the steel wire rope 4 The guide block and the guide groove play a guiding and limiting role, making the movement of the first fixed plate 51 more stable; while the first fixed plate 51 moves to the left to fix the wire rope 4, it drives the second fixing devices 6 on both sides to move, and the first fixed plate 51 drives the connecting shaft 61 and the upper end gear 63 to move to the left.
