A sleeve for preventing nuts and washers from falling off

technical field

The utility model relates to a sleeve for preventing nuts and gaskets from falling off.

Background technique

In the insulating glove operation method of 10kV distribution network line live work, it is a very frequent action to turn the nut. In the operation of disconnecting the branch lead wire, replacing the gram, changing the switch knife, etc., the operator needs to rotate the nut many times. The existing technology requires operators to wear insulating gloves to directly install small gaskets, spring washers and nuts. Due to the characteristics of insulating gloves, it is necessary to wear a pair of anti-stab sheepskin gloves on the outside during operation, and work inside the insulating gloves. The personnel also need to wear a pair of clean spinning gloves. Therefore, during the whole process of live work, the workers have three pairs of spinning gloves, insulating gloves and stab-proof sheepskin gloves on their hands from the inside to the outside.
