Description
Technical field
Power tools technology field is the utility model is related to, more particularly to a kind of retractable electric spanner.
Background technology
Spanner is a kind of conventional installation and extracting tool, is had a wide range of applications in daily life, and it is typically to use
To tighten or unscrew bolt, screw, nut and other screw elements.Spanner is generally formed with grip bolt in the one or both ends of shank
Or the opening or sets of holes of nut, threadingly direction of rotation applies external force in shank during use, with regard to that can twist bolt or nut.It is conventional
Spanner have a manual wrench and electric wrench, manual wrench has that simple to operate, price is low, but labor intensity is big, efficiency is low
Feature, electric wrench have the advantages of easy to operate, labor intensity is low, efficiency high.
Conventional manual wrench is divided into fork spanner（Open-end wrench, double offset ring spanner, box spanner etc.）, ratchet spanner etc..Open
The fork spanners such as mouth spanner, double offset ring spanner, box spanner tighten or unscrewing operation in, by screw element rotate one less turn
Just needing to remove spanner from screw element behind angle, spanner then is changed into an angle again is placed on to be rotated further on screw element, this
Individual process is generally to be repeated, and repeatedly until screw element is fully tightened or unclamped, therefore operation is inconvenient, and fork spanner is general not
It is adapted to use in some narrow spaces.The nip part of ratchet spanner is usually enclosed construction, to realize and tighten or unscrew spiral shell
Ratchet spanner need to be entangled screw element by line part from the top of screw element or bottom, and user must grip wrench body and reciprocal
Ground, which swings, can just be such that ratchet ring rotates in a unidirectional manner and drive sleeve and the nut for driving sleeve connection, and it is many to expend user
Time, the especially construction environment to long bolt, user must carry out tightening or unscrewing for a long time to nut, narrow for space
Small, long and narrow construction environment, user can only low-angle reciprocally pull back and forth, it is fairly time consuming laborious for user.
To improve operating efficiency and the convenience that uses, there are some electric wrenches in the market, however, these electronic are pulled
The work head of hand is usually closed tube-in-tube structure, and is only capable of using in the case where bolt is shorter and space is enough.In vapour
In car maintenance or Decoration Industry, there is the situation that many bolts are long or space is long and narrow, the former needs electric wrench to coordinate long sleeve
Using, the latter needs right angle electric wrench to coordinate short sleeve to use, and so reduces the convenience used, and for height only
Space or long and narrow space slightly larger than bolt length, then common electric wrench can not be used to carry out operation.
