The first fixing plate 101 and the second fixing plate 102 are the same in shape and size. The limiting rod 103 passes through the first fixing plate 101 and is slidably connected to the first fixing plate 101. One end of the limiting spring 104 is fixedly connected to the first fixing plate 101, and the other end of the limiting spring 104 is fixedly connected to the second fixing plate 102.
