[0046] Embodiment two:

[0047] In combination Figures 9-12The difference between the second embodiment and the first embodiment is that the elastic buckle arm (4) is a plastic part or a die casting part which is fixed on the fixed seat (2) by integral molding, and the fixed seat (2) forms an integral whole which cannot be disassembled. Specifically, the elastic buckle arm (4) is a plastic part which is integrally molded on the fixed seat (2) by injection molding, and the fixed seat (2) forms an integral whole which cannot be disassembled. Alternatively, the elastic buckle arm (4) is a die casting part which is integrally molded on the fixed seat (2) by die casting, and the fixed seat (2) forms an integral whole which cannot be disassembled.
