Abstract
It the utility model is related to a kind of Novel stretchable inner hexagon spanner, including fixed handle, kink, connector, hexagonal wrench head, wherein connected between fixed handle lower end and connector by kink, kink makes the axis of fixed handle vertical with the axis of connector, it is hexagonal wrench head on the top of connector, it is characterised in that：The circumscribed circle diameter of the hexagonal wrench head is equal to the diameter of connector；Hollow and open top in the fixed handle, nut is fixedly installed on the top of fixed handle；The Telescopic handle is arranged on the hollow space of fixed handle, to be threadedly coupled between Telescopic handle and nut, and is provided with taper knob on the top of Telescopic handle；The circumscribed circle diameter of the hexagonal wrench head of the spanner is set identical with the diameter of connector, the torsional strength of hexagonal wrench head and connector junction can thus be increased, improve the service life of spanner, Telescopic handle is also added simultaneously, this can increase the moment of torsion of spanner, make people's more easily demounting bolt.
Description
Technical field
A kind of Novel stretchable inner hexagon spanner is the utility model is related to, belongs to mechanical maintenance tool in use field.
Background technology
Inner hexagon spanner is also allen wrench.Inner hexagon spanner applies the active force to screw by moment of torsion, substantially reduces
The use force intensity of user, is useful tool indispensable in industrial manufacturing industry.Particularly in motor vehicle repair and heavy machine
Tool field, inner hexagon spanner are widely used.When dismantling some larger hexagonal socket nuts, inner hexagon spanner is generally required
There is higher intensity.Stress concentration can occur common inner hexagon spanner for 90 ° of bending parts at work, produce larger stress, such as
Fruit intensity deficiency is easily broken, and puzzlement is brought to user.In current technology, common inner hexagon spanner all passes through
Change material and processing technology to improve the intensity of inner hexagon spanner, can so cause inner hexagon spanner cost high, expensive.
And when dismantling some and being difficult to the nut dismantled, the arm of force of spanner can not extend, and cause engineering staff's use of having to very big
Power can just pull down nut or cause spanner to be broken.
The content of the invention
The purpose of this utility model is to provide a kind of Novel stretchable inner hexagon spanner, to solve existing inner hexagon spanner
Torsional strength is low, and the problem of use sweat.
A kind of Novel stretchable inner hexagon spanner, including fixed handle, kink, connector, hexagonal wrench head, wherein fixed
Connected between handle lower end and connector by kink, kink makes the axis of fixed handle vertical with the axis of connector, even
The top of joint is hexagonal wrench head.In use, hexagonal wrench head is inserted on stud, fixed handle is then held, by pulling
Fixed handle rotates hexagonal wrench head, and then tightens or loose bolts.The circumscribed circle diameter of the hexagonal wrench head is equal to connection
The diameter of head.The diameter of the circumscribed circle diameter of hexagonal wrench head and connector is arranged to identical parameters, then can reduce connection
The internal stress that head is connected out with hexagonal wrench head, increase connector and the torsional strength of the junction of interior hexagonal wrench head.It is described
Hollow and open top in fixed handle, nut is fixedly installed on the top of fixed handle；The Telescopic handle is arranged in fixed handle
Empty part, to be threadedly coupled between Telescopic handle and nut, and taper knob is provided with the top of Telescopic handle.Because some bolts are fixed
Ratio it is stronger, people can not easily be disassembled very much, by adding Telescopic handle on fixed handle, can be increased this and be pulled
The arm of force of hand, allow people's more easily demounting bolt.The side of the nut is provided with magnet, as illustrated, in nut
Side be provided with magnet after can by different size of spanner arrange be attached together, this can be with the collection of convenient wrench with taking
Band.
The beneficial effects of the utility model are：The spanner is improved traditional inner hexagon spanner, by its hexagonal wrench
The circumscribed circle diameter of head is set identical with the diameter of connector, can thus increase hexagonal wrench head and connector junction
Torsional strength, improve the service life of spanner, while also added Telescopic handle, this can increase the moment of torsion of spanner, make people
More easily demounting bolt.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is multiple monomer receiving state structural representations of the present utility model.
In figure, fixed handle 1, kink 2, connector 3, hexagonal wrench are first 4, Telescopic handle 5, nut 6, taper knob 7, magnet 8.
Embodiment
It is better embodiment of the present utility model below, but does not therefore limit the scope of protection of the utility model.
As illustrated, a kind of Novel stretchable inner hexagon spanner, including fixed handle 1, kink 2, connector 3, six ribs are pulled
At hand 4, wherein connected between the lower end of fixed handle 1 and connector 3 by kink 2, kink 2 makes axis and the company of fixed handle 1
The axis of joint 3 is vertical, is hexagonal wrench first 4 on the top of connector 3.In use, hexagonal wrench first 4 is inserted on stud,
Then fixed handle 1 is held, hexagonal wrench first 4 is rotated by pulling fixed handle 1, and then is tightened or loose bolts.Six rib
The circumscribed circle diameter of driving end 4 is equal to the diameter of connector 3.By the circumscribed circle diameter of hexagonal wrench first 4 and the diameter of connector 3
It is arranged to identical parameters, then can reduces the internal stress that connector 3 is connected out with hexagonal wrench first 4, increase connector 3 and interior six
The torsional strength of the junction of rib driving end 4.Hollow and open top in the fixed handle 1, fix and set on the top of fixed handle 1
Put nut 6；The Telescopic handle 5 is arranged on the hollow space of fixed handle 1, to be threadedly coupled between Telescopic handle 5 and nut 6, and
The top of Telescopic handle 5 is provided with taper knob 7.Because the ratio that some bolts are fixed is stronger, people can not easily be dismantled very much
Get off, by adding Telescopic handle 5 on fixed handle 1, the arm of force of the spanner can be increased, people is more easily dismantled
Bolt.The side of the nut 6 is provided with magnet 8, as shown in Fig. 2 can will be different big after magnet 8 is provided with the side of nut 6
Small spanner arrangement is attached together, and this can be with the collection and carrying of convenient wrench.
The utility model devises a kind of Novel stretchable inner hexagon spanner, and the spanner changes to traditional inner hexagon spanner
Enter, by the identical with the diameter of connector of the circumscribed circle diameter setting of its hexagonal wrench head, can thus increase hexagonal wrench
Head and the torsional strength of connector junction, improve the service life of spanner, while have also added Telescopic handle, and this, which can increase, pulls
The moment of torsion of hand, make people's more easily demounting bolt.
