Through the movement of the moving plate, the moving plate drives the L-shaped seat to move in the direction away from the sleeve through the L-shaped connecting plate, and then drives the moving seat to move synchronously in the direction away from the sleeve, providing power for the L-shaped seat to move outside the box body.
