The limiting function will be described in detail below.
[0022] The reinforcing rib 52 is welded on the outer side (non-adhesion side of the product) of the moving support plate 51, the buffer block 53 is fixed on the inner side (adhesion side of the product) of the moving support plate 51 by bonding or bolts, the hand-held plug pin 54 is arranged in the circular mounting hole of the moving support plate 51, and the sliding block 55 is fixed on both ends of the moving support plate 51 by bolts and is in sliding connection with the guide rail 42.
