Specifically, when fixing the wire harness 7, the wire harness 7 is passed through the notch 141b, the wire harness 7 squeezes the wire buckle 141, and the wire buckle 141 produces a certain elastic deformation so that the notch 141b is stretched, and the notch 141b is stretched open Afterwards, the wire harness 7 passes through the notch 141b and is placed in the wire fixing groove 141a, the notch 141b is restored to its original shape, and the notch 141b can block and limit the wire harness 7, so as to reduce the probability of the wire harness 7 coming out of the wire fixing groove 141a .

In one embodiment, please refer to FIG. 15 , at least two elastic arms 1411 are also arranged in the lifting rib 14, one end of the elastic arm 1411 is connected to the wire buckle 141, the other end of the elastic arm 1411 is a free end, and the two elastic arms 1411 The free ends of the wires are arranged at intervals to define a wire clamping opening 141c for the wire harness 7 to be clamped in. The wire clamping opening 141c communicates with the notch 141b, and the opening size of the wire clamping opening 141c is smaller than the opening size of the notch 141b. That is to say, when the wire harness 7 passes through the wire clamping opening 141c, the free ends of the two elastic arms 1411 are stretched apart under the action of elastic force, and after the wire harness 7 passes through the wire clamping opening 141c, the free ends of the two elastic arms 1411 return to their original shape , the wire harness 7 passing through the wire clamping opening 141c is put into the wire fixing groove 141a from the notch 141b.

Since the opening size of the clamping hole 141c is smaller than the opening size of the notch 141b, the wire harness 7 can be blocked after the wire harness 7 is loosened from the wire fixing groove 141a due to an accident, so as to prevent the loose wire harness 7 from hitting the inner cylinder 11 and/or lifting ribs 14 to cause the wire harness 7 to wear and tear.

In one embodiment, please refer to FIG. 15 , the free ends of the two elastic arms 1411 are arranged obliquely toward the clamping direction of the wire harness 7 , and the distance H1 between the ends of the two elastic arms 1411 for connecting with the wire buckle 141 is greater than the free ends. The distance H2 between the ends, when the wire harness 7 is loosened from the fixed wire groove 141a due to accidents, the wire harness 7 is against the free ends of the two elastic arms 1411, once the wire harness 7 moves outward, it will squeeze the elastic arms 1411, will force the elastic deformation of the two elastic arms 1411 outward, so that the distance between the free ends of the two elastic arms 1411 will become smaller and smaller, causing the wire harness 7 to move from the free end of the two elastic arms 1411 The chances of loosening at the spacer are getting smaller and smaller.

For example, please refer to FIG. 14 , there are multiple wire ties 141 , and the plurality of wire ties 141 are arranged at intervals along the axial direction of the cylinder body 111 , thereby enabling the wire harness 7 to be fixed more firmly.

It can be understood that, in other implementation manners, the elastic arm 1411 may not be provided.
