When the guiding plate 2015 slides along the guiding column 2017 and moves away from the vertical plate 2011, the limiting effect on the sliding plate 2013 is released. At this time, the spring 2012 resets to drive the sliding plate 2013 to slide along the guiding column 2017. At the same time, both of the two supporting wheels 2014 slide along the first splicing plate 1 to ensure the stability of the sliding plate 2013 during movement, and drive the L-shaped inserting frame 208 to move horizontally until it is inserted into the slot 202 to limit the U-shaped plate 201, and finally ensure the firm connection between the first splicing plate 1 and the second splicing plate 3.
