[0026] A transverse light rod 10 is also fixed inside the U-shaped fixing frame 6. The transverse light rod 10 passes through the inside of the L-shaped movable plate 5 and is slidably connected to the L-shaped movable plate 5. Through the arrangement of the transverse light rod 10, the L-shaped movable plate 5 can slide on the outside of the transverse light rod 10, so that the transverse light rod 10 can limit the moving track of the L-shaped movable plate 5, thereby making the movement of the L-shaped movable plate 5 smoother;
