Abstract
The invention relates to a low-voltage live working tool, in particular to a low-voltage live working screwdriver. The low-voltage live working screwdriver comprises a handle, a rod part and a tip end which are similar to the structure of an ordinary screwdriver, wherein an insulated rubber sleeve is sleeved on the rod part of the screwdriver, and the root of the insulated rubber sleeve is connected with the handle; and the top of the insulated rubber sleeve is 2-4mm longer than the tip end. The screwdriver has simple structure and convenient manufacture and mounting, and through the insulated rubber sleeve, the rod part of the screwdriver is insulated and protected, thereby short circuits caused by false touches in live work are prevented, and the safety of operations is improved. In addition, because the insulated rubber sleeve is longer than the tip end of the screwdriver for a section of length, the elasticity and the frication of the material of the insulated rubber sleeve can be utilized to fix a screw at the front end of the screwdriver, which greatly facilitates the live mounting operation of the screw.
Description
Technical field
The present invention relates to a kind of low-voltage live line work instrument, specifically is a kind of livewire work screwdriver.
Background technology
In the repair and maintenance process of low-voltage power line, often need carry out livewire work, as operations such as the online dismounting of carrying out electric energy meter and installations.In carrying out the livewire work process, use the normal screws cutter to exist following problem: 1, the metallic rod portion of screwdriver is easy to mistake and bumps live wire and cause short circuit, has reduced processing safety; 2, in the hot line job, the operator can not directly contact the screw that will install, make troubles for the location and the installation of screw, existing structure normally adopts the screwdriver of carrying magnetic end to solve this problem, but cause suction to descend with long-time use of magnetic screw driver coping screw cutter or problem of materials own, screw is come off easily, thereby use still inconvenient.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of simple in structure, safety in utilization good, hot line job low-voltage live line work screwdriver easily.
Low-voltage live line work of the present invention has the handle similar to the normal screws knife structure, bar portion and tip with screwdriver, it is characterized in that: be with an insulation rubber sleeve in the bar portion of screwdriver.
The root and the handle of described insulation rubber sleeve join, and the top of insulation rubber sleeve grows 2～4mm than above-mentioned tip.
The present invention is simple in structure, manufacturing and easy for installation; It makes the bar portion of screwdriver obtain insulating protection by insulation rubber sleeve, has prevented that the mistake in the livewire work from bumping short circuit, has improved the security of operation; In addition,, can utilize the elasticity of electro-insulating rubber cover material itself and friction that screw is fixed on the screwdriver front end, greatly facilitate the charged fitting operation of screw because insulation rubber sleeve grows the most advanced and sophisticated segment length of screwdriver.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in the figure, this low-voltage live line work has handle 1, bar portion 2 and tip 3 with screwdriver, is with an insulation rubber sleeve 4 in the bar portion 2 of screwdriver.The root of insulation rubber sleeve 4 and handle 1 join, and the top of insulation rubber sleeve 4 grows 2～4mm than most advanced and sophisticated 3.
