[0026] Furthermore, two groups of fixed rods 23 are provided, and a circular hole is opened on the surface of the fixed rod 23. The rotating rod 24 rotates on the circular hole of the fixed rod 23. The two ends of the rotating rod 24 are limit blocks, and the limit blocks rotate with the rotating rod 24.
