Abstract

The invention relates to a sleeve capable of preventing a nut and a spacer from falling off. The sleeve comprises a cylinder and an adapter, the adapter is detachably connected on the cylinder, a placing groove is formed in one end of the adapter, a through hole is formed in the placing groove, a magnet absorption component is arranged in the cylinder, one end of the magnet absorption component is arranged in the through hole, a push component is arranged in the cylinder, a reset spring is arranged in the cylinder, one end of the reset spring is connected with the magnet absorption component, the other end of the reset spring is connected with the push component, and an absorption magnet is arranged on the adapter. The sleeve has the advantages that the nut is sucked in the placing groove by the magnet absorption component, the spacer is sucked in the placing groove by the absorption magnet, the nut can be conveniently and rapidly fastened by rotating the cylinder in the live working process, the nut and the spacer can be effectively prevented from falling off in the live working process, time of operating workers contacting with an electrified body is greatly shortened in the live working process, times of the operating workers contacting with the electrified body is decreased in the live working process, live working safety coefficients are greatly improved, and working efficiency is improved.

Description

technical field

[0001] The invention relates to a sleeve for preventing nuts and gaskets from falling off. Background technique

[0002] 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, so during the whole process of live work, the workers have three pairs of spinning gloves, insulating gloves and stab-resistant sheepskin gloves on their hands from the inside to the out...
