[0030] When the tube body 1 is placed on the desktop, the slide plate 58 moves upward under the action of gravity, and at the same time, the spring 1 581 undergoes elastic deformation. When the slide plate 58 moves, the moving rod 57 fixedly connected to the slide plate 58 moves upward synchronously. When the moving rod 57 moves, the moving rod 57 will squeeze the block 55, so that the block 55 slides to the outside of the tube body 1. At the same time, the spring 1 56 undergoes elastic deformation.
