Technical Field

The utility model relates to the technical field of electrical maintenance tools, in particular to a maintenance tool for electrical engineering.

Background

Electrical equipment is a generic term for equipment such as generators, transformers, power lines, circuit breakers, etc. in an electrical power system.

The conventional maintenance and repair tool for electrical equipment is generally characterized in that a straight metal rod is connected to an insulating handle, and the diameter of the insulating handle is larger than that of the metal rod. One end of the metal rod is connected with the insulating handle, the other end of the metal rod is provided with a tool bit, and the tool bit is provided with a straight tool bit, a cross tool bit or an inner hexagonal tool bit. The conventional hydraulic generator and the electric equipment maintenance and repair tool have different specifications, but the total length generally exceeds 10cm, and during operation, the conventional hydraulic generator and the electric equipment maintenance and repair tool need to be perpendicular to an operation surface, so the conventional hydraulic generator and the electric equipment maintenance and repair tool require a larger operation space. The maintenance of local maintenance is often required to be carried out to electrical equipment in the electrical industry, but when carrying out local maintenance to electrical equipment, can not dismantle electrical equipment on a large scale, and the space that can supply the operation often only has several centimetres, because the narrow and small factor in space, conventional hydraulic generator and electrical equipment maintenance and repair instrument can not normally carry out upright operation in the space, lead to the contact not to the screw that needs dismantle or install, make maintenance work become very inconvenient, greatly influence work efficiency.
