Abstract

The invention discloses an insulation spanner with the self-locking function. The insulation spanner comprises a handle and a spanner body. One end of the spanner body is connected with the handle. Two fixing openings are formed in the other end of the spanner body. A self-locking device is installed on one fixing opening. The insulation spanner has the advantages that the handle is made of insulation epoxy resin, the spanner can be electrified to emergently maintain devices, and therefore operation safety of emergency maintenance personnel is guaranteed. Besides, the self-locking device is installed on one fixing opening of the spanner body to lock a nut, a gasket and a spring cushion, so that parts are prevented from disengaging, great convenience is brought for constructors, and safety potential hazards caused by dropping of the parts are also avoided.

Description

technical field [0001] The invention relates to a fastening tool; in particular, it relates to an insulating wrench used in the power supply industry. Background technique [0002] Due to the quality problems of the equipment itself, problems with the installation or improper connection process, poor contact of the connection parts, aging equipment, large load and other problems of the power equipment in the power supply industry, the joints will heat up. Due to load requirements and power outage time constraints, defective equipment cannot be repaired in a timely manner, and live work can only be used to deal with it. [0003] At present, the ratchet wrench used in live work is hand-held, small in size, light in weight, and easy to operate. However, because it is a high-altitude live work worker, it is necessary to wear insulating gloves. Spring pad. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an insulatin...
