Difference；In addition during old equipment is dismantled, the corrosion screw that common wrench is difficult to loosen easily is run into.
Utility model content
The purpose of this utility model is that it is directed to drawbacks described above of the prior art, there is provided it is a kind of simple in structure, it can be lifted
The general arm of force lengthener of large torque screw tightness and corrosion screw loose unloading work efficiency.
To realize above-mentioned purpose of utility model, the utility model employs following technical solution：A kind of general arm of force lengthens
Device, including principal arm, at least one spacing screw piece, at least one Coupling；Principal arm inner hollow, and be provided with its perisporium to
A few limit hole；At least one spacing screw piece is detachably coupled with least one limit hole respectively；At least one Coupling
Removably it is sleeved on inside principal arm front end, for being socketed hand-held tool shank.
In addition, the utility model also provides following attached technical scheme：
General arm of force lengthener further includes the extension arm for being removably socketed in principal arm afterbody.
Principal arm rear end is internally provided with internal thread, and external screw thread, extension arm and principal arm phase are provided with the extension arm outer wall
Mutually it is threadedly coupled.
General arm of force lengthener further includes the block removably matched somebody with somebody and be connected on the principal arm front end, and use is provided with the block
In the through hole passed through for hand-held tool shank.
External screw thread is provided with the outer arm of principal arm front end, the block is internally provided with external screw thread, block and the mutual spiral shell of principal arm
Line connects.
Rubber handle set is provided with the outer wall of the second half section of principal arm.
Principal arm is in cylinder；At least one Coupling is provided with and matches with hand-held tool shank in cylinder
Through hole.
Compared with the prior art, the advantage of the utility model is：Disclose a kind of general arm of force lengthener, the device bag
Include principal arm, at least one spacing screw piece, at least one Coupling.The setting of principal arm increases torque arm length, according to lever principle,
Staff will pay less power when dismantling screw element, improve work efficiency.At least one Coupling is set to can be used for
The handle of at least one hand-held tool is coupled so that the present apparatus has multifunctionality, versatile.At least one spacing screw piece is main
It is spacing for being carried out to the handle of hand-held tool, improve connective stability.For synthesis, the general arm of force lengthener of the utility model
It is simple in structure, it is versatile, it is securely and reliably, simple light, tear group open rapidly, it is cheap practical, large torque screw can be substantially improved
It is elastic, and the efficiency of corrosion screw loose unloading work.
Brief description of the drawings
In order to illustrate more clearly of the technical solution of the utility model embodiment, embodiment or correlation technique will be retouched below
Attached drawing is briefly described needed in stating, it should be apparent that, it is new that drawings in the following description merely relate to this practicality
Some embodiments of type, are not limitation of the utility model.
Fig. 1 is the design of part schematic diagram of the general arm of force lengthener of the utility model preferred embodiment.
Fig. 2 is the operating diagram of the general arm of force lengthener of the utility model preferred embodiment.
Embodiment
In order to be more clearly understood that the above-mentioned purpose of the utility model, feature and advantage, below in conjunction with the accompanying drawings and have
Body embodiment makees technical solutions of the utility model further nonrestrictive detailed description.
See Fig. 1 and Fig. 2, the general arm of force lengthener of the present embodiment includes 2, three sets of the spacing screw piece of a principal arm 1, four
3, blocks 4 of fitting and an extension arm 5.
Principal arm 1 is overall to be provided with external screw thread area in cylinder, inner hollow, front end outer wall, and rear end inner wall is provided with interior spiral shell
Line area.For the ease of gripping, 1 rear end of principal arm is arranged with rubber handle set.Four limit holes are provided with the periphery of principal arm 1
6, which is distributed in four orientation of 1 periphery of principal arm, and is moved successively toward rear end.Four spacing screw pieces 2 can
Mutually it is threadedly coupled with aforementioned four limit hole 6 respectively.
Coupling 3 is in cylinder, and the through hole to match from different hand-held tool shanks is both provided with each Coupling 3, than
Such as triangle, square and circular, it is common that such as monkey wrench, torque spanner, sharp-end ratchet wrench, hand hammer, hatchet can be matched
The handle of instrument, the plurality of specifications such as M10, M12, M14, M16, M18, M20 can be adapted to for monkey wrench.Therefore the present embodiment
General arm of force lengthener there is general applicability.
In cylinder, it has a thread bush and a baffle for being arranged on thread bush wherein one end, thread bush for block 4
Internal thread is provided with inner wall, the through hole for being passed through for hand-held tool shank is provided with baffle.Coupling 3 makes in order to prevent
