Abstract
The invention relates to an overhaul spanner with the nut preassembling and recycling function. The overhaul spanner comprises an operating rod and a sleeve assembly. The sleeve assembly is connected to the operating rod and comprises a sleeve body, elastic rings and movable contact blocks. The sleeve body is provided with axial containing holes and radial slippage holes. The radial slippage holes communicate with the axial containing holes. The movable contact blocks are in slippage connection with the radial slippage holes. When the elastic rings compress the movable contact blocks, the movable contact blocks stretch into the corresponding axial containing holes. The elastic rings are arranged on the periphery of the sleeve body in a sleeving mode, and the outer ends of the movable contact blocks are limited through the elastic rings. The overhaul spanner with the nut preassembling and recycling function is particularly suitable for production assembling and trouble shooting in a narrow space.
Description
Technical field
The present invention relates to a kind of service kit, especially a kind of with the maintenance spanner for pre-installing and reclaiming nut function.
Background technology
Power electronic equipment in production assembling and trouble shooting procedure needs to install or remove substantial amounts of bolt and nut.
Thus, in current industry when power electronic product design is carried out, it is required for reserving larger behaviour to spanner and operative employee's arm
Make space.However, as the continuous development of power industry, the volume of power electronic equipment are less and less, structure is also more and more tighter
Gather, the hidden link position in some narrow spaces and position often occur.Operator are installing or removing above-mentioned position
Because difficulty is larger during bolt and nut, often the findings such as bolt and nut can be dropped.Production efficiency is so not only affected, and is set
Standby normal operation brings hidden danger.
At this stage, it is still to adopt the side for reserving larger working place or breaking whole product from outside to inside in power industry
Formula, not only constrains the development progress of facility compact but also installation effectiveness is relatively low.And nut is needed after having dismantled manually
Reclaim, it is impossible to directly reclaimed by overhauling spanner.
