When the locking pin 18 slides, it can drive the sliding piece 19 to slide inside the support plate 17. The sliding piece 19 squeezes the spring 22, causing the spring 22 to compress. When the locking pin 18 slides completely into the support plate 17, rotating the telescopic plate 13 drives the telescopic plate 13 to rotate on the outer wall of the fixed shaft 12, and simultaneously drives... The rotating plate 15 rotates on the outer wall of the rotating shaft 14, thereby driving the sliding shaft 16 to slide in the groove opened inside the support plate 17 until the sliding shaft 16 slides to the bottom of the groove. At this time, by rotating the two rotating blocks 21 below the support plate 17, the rotating shaft 20 can be driven to rotate, thereby driving the locking post 18 to slide. Through the rebound of the spring 22, the sliding piece 19 can be driven to slide, thereby driving the locking post 18 to slide into the interior of the groove, so as to achieve the effect of limiting the sliding shaft 16 by the locking post 18, thereby achieving the effect of limiting the folding of the telescopic plate 13.

[0044] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.
