The inside of the mounting frame 5 is fixedly connected with the first reinforcement rib 9, and the outside of the movable pulley 6 is slidably installed with a guide rail 8.
[0027] It should be noted that there are four movable pulleys 6, which are evenly distributed at the bottom of the mounting frame 5.
