When the tempered glass 3 is not needed, the limiting rod 12 is retracted into the sleeve 13. The limiting rod 12 is withdrawn from the limiting rod mounting hole 10 and the second limiting groove 19. Then, the extension rod 9 can be retracted into the supporting leg 7. When the bottom end of the extension rod 9 is flush with the bottom end of the tempered glass 3, the first limiting groove 11 is aligned with the limiting rod mounting hole 10. Then, the spring 16 pushes the spring plate 14, and the spring plate 14 pushes the limiting rod 12, so that the limiting rod 12 is inserted into the limiting rod mounting hole 10 and the first limiting groove 11 again, thereby preventing the extension rod 9 from being pulled out of the supporting leg 7. Then, the supporting leg 7 is rotated to be parallel to the tempered glass 3, so that the storage area of the tempered glass 3 is reduced when the tempered glass 3 is not needed.
