The moving rod 701 pushes the two oblique rods 702 to the opposite side by cooperating with the first rotating shaft. The oblique rod 702 pushes the vertical rod 703 to move forward by cooperating with the second rotating shaft. The vertical rod 703 drives the cross rod 801 to move forward. The cross rod 801 drives the positioning rod 802 to move forward according to the moving trajectory provided by the limiting groove 10, and at the same time stretches the tension spring 803 to move the positioning rod 802 to the inside of the positioning cavity 6. At this time, the expansion plate 5 can be unfolded according to the moving trajectory provided by the sliding groove 12. After completion, the two expansion plates 5 are pushed to the opposite side again and the moving rod 701 is released.
