Description

Technical Field

[0001] The utility model relates to the technical field of construction tools, in particular to a high-efficiency construction tool for electric power engineering. Background Art

[0002] Power engineering is engineering related to the production, transmission and distribution of electric energy. The transmission and distribution of electric energy is mainly achieved through high and low voltage AC power networks, and countless orderly connected cables are the carriers of power transmission. The connection between low-voltage cables is mostly done by electricians manually twisting the wires: using pliers such as pliers or wire cutters to cut off the cable ends and peel off the sheath, and then wrap the two exposed cable wires and cover them with insulating materials to complete the connection between the two cables. However, this type of pliers is limited to cutting thinner cables, has poor applicability, and is inefficient.

[0003] In the patent document with the publication number CN 216530269 U, an efficient construction tool for electric power engineering is disclosed, which includes an adjustment seat, an adjustment rod is provided on one side of the adjustment seat, and a blade is provided inside the adjustment rod. The cable end is placed between the two blades, and the adjustment seat is held and rotated around the cable, so as to cut the cable sheath and realize fast cable stripping. Although this patent improves the stripping efficiency of the cable, the operation method of holding the adjustment seat and rotating around the cable is very inconvenient.

[0004] To this end, the utility model provides a high-efficiency construction tool for electric power engineering, which can not only improve the cutting efficiency of cables, but also improve the convenience of use. Utility Model Content
