A pulley body 4 is installed on the adjacent side of the protective plate 3. A bushing 17 is installed through the middle of the side wall of wheel body 4, and a shaft 18 is installed through the side wall of bushing 17. A buckle 7 is fixedly connected to the middle of the two adjacent support plates 1. The buckle 7 enables quick initial connection and positioning. The front support plate 1 is connected to connecting block 1 8 via the buckle 7. Sliding grooves 9 are provided on both the left and right ends of the outer wall of connecting block 1 8. The rear support plate 1 is connected to connecting block 2 10 via the buckle 7. Sliding rods 12 are fixedly connected to both the left and right ends of the front side of connecting block 2 10.
