Abstract

The invention discloses an expansion buckle. The expansion buckle comprises a base, an inserting head piece and an expansion piece; the base is internally provided with a first cavity and a second cavity, the first cavity is separated from the second cavity through a cavity partition plate, and the cavity partition plate is provided with a limiting piece passing hole; the limiting piece passing hole communicates with the first cavity and the second cavity; the expansion piece is fixed to the base; the inserting head piece comprises an inserting head piece body and a first limiting piece; and the first limiting piece is fixed to the inserting head piece body and is matched with the limiting piece passing hole so that the first limiting piece can enter or leave the second cavity through thelimiting piece passing hole. According to the expansion buckle, the inserting head piece and the base are locked and matched in a rotary locking mode, thus, assembling and disassembling are more convenient, disassembling can be completed without using tools, and damage to the expansion buckle in the disassembling process is reduced.

Description

technical field [0001] The invention relates to buckles, in particular to an expansion buckle. Background technique [0002] Plastic expansion buckles are often used in the installation and fixing process of vehicle parts at the present stage. The plastic expansion buckles in the prior art generally use threaded limit or snap-fit ​​limit push pins. Although the above-mentioned method facilitates the clamping and fixing of the buckle, the above-mentioned buckle needs to be disassembled with a screwdriver or a special tool; the disassembly is laborious, resulting in poor disassembly convenience, and the push pin is easy to be damaged during the disassembly process The buckle foot reduces the number of times the buckle is used. Contents of the invention [0003] The purpose of the present invention is to provide an expansion buckle to solve the shortcomings in the prior art, which can be more conveniently installed and disassembled, and the damage to the expansion buckle is ...
