Abstract
The invention discloses a power transfer joint of an electric spanner. The power transfer joint comprises a reverse gear set and an electric spanner joint; the reverse gear set is connected with the electric spanner joint through a lengthened rod; the reverse gear set includes brackets and conical gears; the brackets surround the conical gears; the conical gears are connected end to end to form a square; and sleeve holes are formed in the brackets corresponding to the external center positions of the conical gears. The power transfer joint of the electric spanner has the advantages of simple structure, convenience for operation, labor saving in use and lower cost; the power transfer joint can be directly used under narrower working environments; the sleeve holes with different sizes can satisfy different working environment demands; the labor intensity of operators is effectively reduced; and the working efficiency is improved.
Description
Technical field
The present invention relates to field of power tools, particularly a kind of power transmission connector of electric wrench.
Background technology
At present, can not the frock environment of diameter application for automated tools such as electric wrenches, the general servicing units such as cross universal joint that adopt carry out power transmission.When driving shaft rotates, driven shaft can rotate thereupon, has and can swing in any direction around spider center, has so just adapted to angle and the needs that simultaneously change of distance.But angle is larger between cross universal joint axis, the through-drive of power transmission shaft is more uneven, the additional alternate load produced is also larger, more unfavorable to the service life of parts, also transmission efficiency can be reduced, so these between centers angles should be reduced in use as far as possible, be not suitable for the working environment that Comparision is narrow and small.
Summary of the invention
The object of this invention is to provide a kind of power transmission connector of electric wrench that can work under narrow and small environment.
The technical solution used in the present invention is:
A kind of power transmission connector of electric wrench, its innovative point is: comprise commutating tooth wheels and electric wrench joint, described commutating tooth wheels are connected with described electric wrench joint by extension rod, described commutating tooth wheels comprise support, conical gear, described support wraps described conical gear, described conical gear joins end to end, surround one square, the corresponding support in outside hub position of described conical gear has sleeve hole.
Further, engage each other between described conical gear, and in 90 °.
Further, described sleeve hole diameters is not etc.
Beneficial effect of the present invention is as follows:
Structure of the present invention is simple, easy to operate, uses laborsaving, cost is lower, directly can use, and the sleeve hole of different size can meet different working environment demands under narrower and small working environment, effectively reduce the labour intensity of operating personnel, improve operating efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
A kind of power transmission connector of electric wrench as shown in Figure 1, comprise commutating tooth wheels 1 and electric wrench joint 2, described commutating tooth wheels 1 are connected with described electric wrench joint 2 by extension rod 3, described commutating tooth wheels 2 comprise support 1a, conical gear 1b, described support 1a surrounds described conical gear 1b, described conical gear 1b joins end to end, surround one square, the corresponding support 1a in outside hub position of described conical gear 1b has sleeve hole 1c.
The above is the preferred embodiment of the present invention, can not limit the interest field of the present invention with this.It should be pointed out that for those skilled in the art, technical scheme of the present invention is modified or equivalent replacement, do not depart from protection scope of the present invention.
Claims (3)
1. a power transmission connector of electric wrench, it is characterized in that: comprise commutating tooth wheels and electric wrench joint, described commutating tooth wheels are connected with described electric wrench joint by extension rod, described commutating tooth wheels comprise support, conical gear, described support wraps described conical gear, described conical gear joins end to end, surround one square, the corresponding support in outside hub position of described conical gear has sleeve hole.
