During this period, the storage tube 6 drives the clamping plate 20 through the inclined plate 18 to slide along the guide rod 15 through the guide plate 16, and the guide plate 16 squeezes the top spring 17. Under the action of the top spring 17, the guide plate 16 slides along the guide rod 15, so that the pulley 19 on the clamping plate 20 clamps and fixes the storage tube 6.
