[0003] Currently, the existing wire clips are all products customized according to wires, and the fixed specifications are adapted to the specified cables. This undoubtedly occupies a large amount of resources. While it is not convenient for laying operations, the wire clips used outdoors will also be affected by the daily environment, resulting in thread corrosion or even loosening, which affects the clamping effect on the cable.

[0004] To solve the above problems, a stable and durable wire clip for wire laying is proposed in this application. Content of the Utility Model

[0008] Further, a transfer shaft is arranged inside the upper ends of adjacent wire clips, which is used for rotatably installing the lifting lug and at the same time for docking with the convex shaft block inside the upper end of the wire clip.

[0009] Further, both ends of the blocking pad are provided with side slopes, which are used to dock with the inner ring frame and at the same time increase the occupied space after inward shrinkage to fill the gap between the wire and the wire clip.

[0010] Further, one end of the outer ring frame is provided with a protruding slider, which is rotatably installed inside the annular groove on one side of the positioning ring.

[0011] Further, holes for installing positioning pins are formed on both sides of the positioning ring, and an elastic pad is installed at one end of the hole for fixing the positioning pin to facilitate insertion and extraction.

[0012] Further, the screwing depth of the outer ring frame is used to control the extrusion force of the inner ring frame on the blocking pad, so as to achieve the effect of adjusting the tightness, and it is applicable to the laying of wires of various specifications.

[0013] Further, the limiting frame is of an open structure and can be expanded by an external force to be sleeved on the outside of the wire.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can be conveniently adapted to wires of various specifications during use through the cooperation of the wire clamp and the limiting frame. The extrusion force of the inner ring frame on the side slope makes the blocking pad contract to different states to adjust the extrusion force on the wire. At the same time, the frictional resistance is increased for reinforcement. In addition, the rigid connection is prevented from damaging the wire, achieving the effect of protecting the wire.

[0016] Through the inner and outer double-layer structure of the outer ring frame and the inner ring frame, the utility model can protect the threaded boss from being affected by the daily environment. At the same time, the positioning is formed by the engagement connection of the positioning pin and the positioning hole, which can effectively prevent loosening and ensure the stable clamping of the battery cell, guaranteeing the clamping effect during long-term use.

[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
