Description

A kind of special isolation pullover based on electric wrench
Technical field
The present invention relates to live line tool field, more particularly to a kind of special isolation pullover based on electric wrench.
Background technology
At present, not yet occur a kind of for dedicated connecting sleeve head of the connecting electric wrench with insulating bar, and insulating bar On most of between the connection pullover that carries lean on is cooperation between tooth and tooth.In actual job, operator is using exhausted When edge bar operates electric wrench, the angle between the position adjustment electric wrench and insulating bar according to parallel groove clamp is understood, by It is general more than 2 meters in insulation pole length, when small variations occur for the angle between electric wrench and insulating bar, electric wrench phase Larger displacement can occur for parallel groove clamp, and by the angle for connecting pullover rotation coordinated between tooth and tooth and cover head plane On the number of teeth it is relevant, anyway increase set head surface on the number of teeth, can not all accomplish the folder between electric wrench and insulating bar Angle is 00-100Between arbitrarily adjust.
In addition, not toothed connection pullover, what is leaned on is that the frictional force covered between head plane is fastened, although the pullover energy Enough realize 3600Angle rotation, but the fine setting of angle difficult to realize, it is also difficult to quantify finely tuned angle.Because being needed during operation Electric wrench sleeve is aligned with the bolt in parallel groove clamp, this required precision to connecting pullover adjustment angle is special Height, if the operator on ground can not accurately be transferred to required angle, it is necessary to constantly unclamp and tighten on pullover Bolt is adjusted, and this brings very big inconvenience to operator, has a strong impact on operating efficiency.
The content of the invention

In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that:It is a kind of special exhausted based on electric wrench Edge pullover, including the first pullover, the second pullover, the upper end of first pullover and the cooperation of electric wrench are fixed, and described second The lower end of pullover is fixedly connected with insulating bar, and the upper end of the lower end of first pullover and second pullover is rotatably assorted company Connect, and first pullover and the second pullover are relatively fixed by goat's horn screw, the arranged on left and right sides of second pullover is set respectively There is left and right through hole, two the first screws are each passed through left and right through hole, the left and right relative of the first pullover is finely tuned by the first screw Position, drives the left and right relative position of regulation electric wrench.
As the further optimization of such scheme, in addition to hook, the shaft side of second pullover leads to provided with first Hole, the hook fixes the hook and second pullover through the first through hole, and by the first nut.
As the further optimization of such scheme, the first pullover includes hollow sleeve, circular support portion and connecting portion, described Hollow sleeve, circular support portion and connecting portion are integrally formed, and the hollow sleeve is above circular support portion, the connection Portion is below the circular support portion, and the lower end of the connecting portion is provided with circular open, the outer toroid of the circular open It is provided with boss.
As the further optimization of such scheme, the top of second pullover is provided with groove, the connection with the first pullover The lower end in portion, which coordinates, to be fixed;
And annular slotted hole and manhole are provided with the groove, the boss of the lower end of the connecting portion, which coordinates, is stuck in annular In slotted eye, the goat's horn screw is relatively fixed institute through manhole in the circular open and groove of the lower end of the connecting portion State the first pullover and the second pullover;
The left and right through hole is respectively arranged on the left and right sides on the top of second pullover, and two the first screws are worn respectively Left and right through hole is crossed, the relative position of the left and right sides of the connecting portion is adjusted, the left and right relative position of the first pullover is finely tuned.
As the further optimization of such scheme, the groove is provided with angle dial.
Compared with the prior art, a kind of beneficial effect of special isolation pullover based on electric wrench of the invention embodies :
1st, a kind of special isolation pullover based on electric wrench of the invention can be with connecting electric wrench and insulating bar, and leads to Cross the wounded in the battle hand the turn of the screw of rotation two round plastics of insulating bar pullover or so carry out angle fine setting electric wrench and insulating bar it Between angle, improve the operating efficiency of operator.
2nd, a kind of special isolation sleeve based on electric wrench of the invention, can be between electric wrench and insulating bar Angle is 00-100Between arbitrarily adjust, accurately adjust the angle between electric wrench and insulating bar, meet job requirements, carry The high operating efficiency of operator.
