Description

Technical Field

[0001] The present invention relates to the technical field of live working pliers, and more particularly to a live working pliers. Background Art

[0002] With the widespread promotion of power circuits, the application of high-voltage transmission and transformation circuits is becoming more and more intensive. High-voltage transmission and transformation circuits are often exposed to the outdoors for a long time. The lines and hardware are easily damaged by rain, snow, wind, lightning, etc. Manual live maintenance is very dangerous, and regular power outages are usually used for maintenance. Power outages of high-voltage transmission and transformation circuits will cause great economic losses. Therefore, live working pliers are widely used.

[0003] After searching, the publication number is: CN201230164, the application number is: CN200820077488.8, the live working pliers include inner and outer insulating rods equipped with return springs, a pliers body arranged at the front end of the insulating rod and a handle connected to the rear end of the insulating rod, a section of the rear part of the inner insulating rod is arranged as a relatively rotatable threaded rod, and a self-locking fixing device composed of a guide sleeve, a locking pin with a pull ring at the upper end and a straight-shaped cutting edge at the lower end arranged in the guide sleeve, a locking spring sleeved on the locking pin, and a spring retaining ring is arranged on the upper end of the guide sleeve. The pull ring embedding groove solves the problem that the operator needs to always apply clamping force after clamping the object, which can effectively reduce the labor intensity of operation and improve work efficiency; and the jaws can be fine-tuned by rotating the threaded rod to facilitate operation; the self-locking function can be used or not by configuring the pull ring embedding groove, which increases the flexibility of using the work pliers. However, when electricians repair high-voltage transmission and transformation circuits, they need to perform many problems such as cutting, stripping, and replacing screws. In actual operation, electricians need to carry more tools and replace them frequently during repair, which makes it inconvenient for electricians to operate. Therefore, there is room for improvement. Summary of the invention
