Abstract
The utility model provides a spanner convenient to operate in narrow and small space, it includes the handle and with the tight end of stinging of handle end connection, stinging tight hand ladle and drawing together the fixed jaw, the tail end of fixed jaw is connecting portion, and connecting portion are connected through pivot and movable jaw, still are equipped with the spring axle on connecting portion, the epaxial compression spring that is equipped with of spring, and two spring arms of compression spring support fixed jaw and movable jaw respectively. The utility model discloses problem inconvenient, that do not operate well in the time of solve using current spanner to dismantle with mounting nut in narrow and small space.
Description
Technical field
The utility model belongs to detection, service kit field, is specifically related to a kind of spanner being convenient to operate in small space.
Background technology
In routine use spanner installation and removal nut process, often encounter the situation that operating space is narrower and small.In this case, need frequently spanner to be taken out, reselect nut stress surface and just can complete installation or removal operation.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and servicing unit prepared by a kind of sample provided, it can solve use existing spanner dismantle in small space and mounting nuts time inconvenience, bad operation problem.
The object of utility model is achieved in that
A kind of spanner being convenient to operate in small space, it comprise handle and be connected with handle end sting tight end, described tightly end of stinging comprises fixed jaw, the tail end of fixed jaw is connecting portion, connecting portion is connected with movable jaw by rotating shaft, connecting portion is also provided with spring shaft, and spring shaft is provided with Compress Spring, and two spring arms of Compress Spring prop up fixed jaw and movable jaw respectively.
Two spring arms of described Compress Spring prop up fixed jaw respectively and movable jaw can make movable jaw be limited to rotate because of the spring arm of compressing Compress Spring when rotating counterclockwise around the shaft.
The one side of described movable jaw is arcwall face.
The arcwall face that a spring arm of described Compress Spring is close to the stationary plane of fixed jaw connecting portion, another spring arm is close to movable jaw.
Adopt said structure, in a free state, under the effect of Compress Spring, movable jaw can be close to the side of fixed jaw, nut can enter between two jaw mouths very easily, during towards a direction rotating spanner, an angle of described movable jaw can prop up a stress surface of nut, thus turns described nut; During towards another one direction rotating spanner, described movable jaw and described nut stress surface can be made to depart from squeezed state, spanner can be made to return back to original state.Like this, only need clockwise and counterclockwise blocked operation just can complete very easily to operate the installation or removal of nut in small space.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Be convenient to the spanner operated in small space as shown in Figure 1, it comprise handle 1 and be connected with handle 1 end sting tight end, described tightly end of stinging comprises fixed jaw 2, the tail end of fixed jaw 2 is connecting portion 3, connecting portion 3 is connected with movable jaw 5 by rotating shaft 4, connecting portion 3 is also provided with spring shaft 6, and spring shaft 6 is provided with Compress Spring 7, and two spring arms of Compress Spring 7 prop up fixed jaw 2 and movable jaw 5 respectively.
Two spring arms of described Compress Spring 7 prop up respectively fixed jaw 2 and movable jaw 5 can make movable jaw 5 around the shaft 4 rotate counterclockwise time be limited to rotate because of the spring arm of compressing Compress Spring 7.
The one side of described movable jaw 5 is arcwall face.
The arcwall face that a spring arm of described Compress Spring 7 is close to the stationary plane of fixed jaw 2 connecting portion, another spring arm is close to movable jaw 5.
Adopt said structure, in a free state, under the effect of Compress Spring, movable jaw can be close to the side of fixed jaw, nut can enter between two jaw mouths very easily, during towards a direction rotating spanner, an angle of described movable jaw can prop up a stress surface of nut, thus turns described nut; During towards another one direction rotating spanner, described movable jaw and described nut stress surface can be made to depart from squeezed state, spanner can be made to return back to original state.Like this, only need clockwise and counterclockwise blocked operation just can complete very easily to operate the installation or removal of nut in small space.
