Meanwhile, the female buckle plate 110 on the same side is correspondingly provided with a buckle hole for the rectangular protrusion 220 to be embedded in, the vertical rectangular protrusion 221 is embedded in the first buckle hole 120, and the horizontal rectangular protrusion 222 is embedded in the second buckle hole 130. In other embodiments, if the position or number of the rectangular protrusions 220 changes, the corresponding holes may also find a corresponding change. The distance that the rectangular protrusion 220 protrudes from the surface of the outer wall of the male buckle plate 210 can also be set to be not more than the thickness of the female buckle plate 110, so that the whole outer wall is complete after buckling.

Referring to fig. 3, the rectangular protrusion 220 may be integrally formed on the male buckle 210, but in this embodiment, in order to improve the deformation capability of the rectangular protrusion 220, the rectangular protrusion 220 is integrally formed on the male buckle 210 by punching, specifically, the long side of the rectangular protrusion 220 is separated from the male buckle 210, so as to form a receiving hole 223, and two ends of the rectangular protrusion 220 are integrally connected to two end edges of the receiving hole 223.
