Two telescopic plates 3 extending to the outside of the fixed plate 2 are slidably inserted inside the fixed plate 2. A plurality of openings are opened on the surface of the fixed plate 2, and a through hole with the same diameter as the opening is opened on the surface of the telescopic plate 3.

[0022] It should be noted that a telescopic reinforcement rod 8 is provided between two adjacent fixed plates 2, and a plurality of telescopic reinforcement rods 8 are fixedly mounted with a placement plate 9 at both the movable and fixed ends, and one side surface of the two placement plates 9 is in contact with one side surface of the fixed plate 2 and one side surface of the telescopic plate 3.
