[0027] In this embodiment, the setting of the spring 54 has the effect of limiting the position of the long strip 53 inside the sliding groove 52.
[0028] Specifically, two protrusions 55 are fixedly mounted on the top surface of the long board 53, and the two protrusions 55 are symmetrically distributed on the top surface of the long board 53. The setting of the protrusions 55 plays an effect of supporting the insertion rod 56.
[0029] Specifically, the surfaces of the two protrusions 55 are fixedly mounted with an insertion rod 56, and the side of the limiting block 4 is provided with two insertion holes 57. The arrangement of the insertion rod 56 and the insertion hole 57 has the effect of limiting the limiting block 4 in the groove 3.
[0030] Specifically, one end of the rod 56 away from the protrusion 55 is located inside the groove 3, and the size of the socket 57 matches the size of the rod 56.
