Technical Field
[0001] The utility model relates to a fixing hardware, in particular to a power line fixing hardware with a positioning function. Background Art
[0002] Hardware, iron or aluminum metal accessories widely used in power transmission lines, are collectively referred to as hardware. Most hardware needs to withstand large tensile forces during operation, and some also need to ensure good electrical contact at the same time. Power hardware is often used to connect cables, wires and equipment in power systems to ensure the flow of current and the transmission of electrical energy. They provide reliable electrical contact to ensure the normal operation of the power system, often by fixing the aluminum stranded wire in the hardware. During the crimping process of power workers, due to errors in their experience and level, there will be deviations during crimping, resulting in unstable joints, and in windy weather, friction will occur between the aluminum stranded wire and the hardware port, causing the aluminum stranded wire to wear, and the aluminum stranded wire at the edge is easily worn short, posing a greater safety hazard.

DETAILED DESCRIPTION
[0013] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0014] Embodiment. A power line fixing hardware with positioning function, comprising: Figure 1-2 As shown, it includes a hardware body 1, an inner bushing 2 is provided on the inner side of the hardware body 1, and evenly distributed guide strips 3 are provided on the outer side of the inner bushing 2. A first positioning hole 4 is provided on the guide strip 3, a wear-resistant pad 5 is provided on the inner side of the inner bushing 2, a connecting ring 6 is provided at one end of the inner bushing 2, and a slot 7 corresponding to the hardware body 1 is provided in the connecting ring 6. A positioning sleeve 8 which can be disassembled and assembled relative to the connecting ring 6 is provided on the outer side of the hardware body 1, and a second positioning hole 9 corresponding to the first positioning hole 4 is provided in the positioning sleeve 8.
[0015] The positioning sleeve 8 is sleeved on the outside of the hardware body 1, and an external thread section is provided at the end thereof.
