Detailed Description

As shown in fig. 1 to 4, a wire harness fixing bracket includes a bracket body 1, and a wire clamping member 2 is provided on the bracket body 1. The wire clamping component 2 comprises a round buckle 3 and/or a rectangular buckle 4, in the embodiment, the wire clamping component 2 comprises a round buckle 3 and a rectangular buckle 4, and the round buckle 3 and the rectangular buckle 4 are arranged in parallel; circular buckle 3 is equipped with circular fixed slot, and rectangle buckle 4 is equipped with the rectangle fixed slot, and one side of circular fixed slot and rectangle fixed slot is equipped with the opening to put into the pencil from the opening part.

In this embodiment, the inner wall of circular fixed slot is equipped with annular protrusion 31, so sets up for circular buckle 3 not only can the fixed cross-section be circular shape pencil, can also fix the bellows through annular protrusion 31 moreover, and annular protrusion 31 can block in the annular on the surface of bellows, avoids the bellows pine to take off and the landing.

In this embodiment, the end portions of the two sides of the opening of the rectangular fixing groove are provided with the barbs 41, and the rectangular wire harness can be clamped after being placed into the rectangular fixing groove through the arranged barbs 41, so that the rectangular wire harness is prevented from falling off.
