The sliding assembly includes two inner walls, and a second channel for placing the power transmission line is formed between the two inner walls. Guide shafts are respectively installed on the outer surfaces of the two inner walls. The guide shaft is embedded in the guide track on the corresponding side.

On the basis of the above-mentioned scheme, the utility model also makes the following improvements:

A threaded through hole is formed along the central axis of the guide shaft on one of the guide shafts, the threaded through hole runs through the guide shaft, and extrusion bolts are installed on the threaded through hole.

The two guide shafts form threaded through holes along the central axis of the guide shafts, the threaded through holes run through the guide shafts, and extruded bolts are installed on the threaded through holes.

An auxiliary terminal is provided on the outer end of the extruded bolt, and an auxiliary through hole radially penetrating the auxiliary terminal is provided on the auxiliary terminal.

The suspension part includes two suspension side walls, each suspension side wall is connected to two outer side walls respectively, and suspension through holes are provided on the suspension side walls, the suspension through holes are connected with stud bolts, and the stud bolts Both ends of the fitting are fitted with suspension nuts.

The suspension part includes two suspension side walls, each suspension side wall is respectively connected to the two outer side walls, and suspension through holes are arranged on the suspension side walls, the suspension through holes are connected by single-head bolts, and the single-head bolts The free end of the fitting is fitted with a suspension nut.

Compared with the prior art, the beneficial effects produced by the utility model are:

1. Set the sliding assembly on the support part, and the transmission line is placed on the sliding assembly. When the transmission line is pulled by an external force, the transmission line will pull the sliding assembly to move back and forth on the support part, and play a buffer role for the transmission line. The wind direction of the transmission line breaking due to external force is reduced.

2. On the sliding assembly, with the help of the threaded through hole opened on the guide shaft, the extrusion bolt cooperates with the threaded through hole, and the rotation of the extrusion bolt squeezes the transmission line into the second channel to fix the transmission line. It can avoid relative sliding of the power transmission line in the second channel, and avoid excessive pulling stroke of the power transmission line, resulting in unbalanced suspension of the power transmission line on the utility model.

3. Double-headed bolts can be used on the holding part, and the clamping nut at either end can be selected to fasten according to the scene during installation; single-headed bolts can also be used, so that the other section corresponding to the clamping nut is a fixed stopper , Compared with clamping nuts, it has a better fixing effect and will not loosen and fall off.
