Abstract
The invention discloses an electric tool, and aims to overcome the defects of a handheld electric tool in the background art. The electric tool comprises a casing handle, a drive motor, an operating output shaft and a transmission shaft, wherein the drive motor is arranged in the casing handle; one end of the transmission shaft is connected with the output shaft of the drive motor, and the other end of the transmission shaft is connected with the operating output shaft; the axis of the transmission shaft is higher than and parallel to that of the output shaft of the drive motor. The electric tool has the advantages that since the transmission shaft is additionally arranged between the output shaft of the drive motor and the operating output shaft, and the transmission shaft enables the operating output shaft to integrally move upwards, so that the electric tool can reduce a torque to the handle, which is generated due to the rotation of the operating shaft, and the handle can be stressed reasonably when an operator grasps the handle; the electric tool is easy to control, and at the same time, the electric tool can enable the electric operation to obtain more freedom and better operation when processing workpieces.
Description
Technical field
The present invention relates to a kind of electric tool, relate in particular to a kind of electric tool of hand-held.
Background technology
Existing a kind of hand held electric tool, this electric tool comprises that inside is provided with the handle case of driving shaft, and outstanding working head is installed on the axis direction of this driving shaft.This electric tool, because working head is positioned on the axis of driving shaft, in use, because the axis of the focus of work and driving shaft is not on same straight line, the moment of torsion that not only makes work output shaft produce grasps electronic work to operator and has a huge impact, stressed unreasonable, be not easy to the control to electronic work, but also can have affected greatly the service life of electric tool.
Summary of the invention
Technical problem to be solved by this invention, is to overcome the shortcoming of hand held electric tool in background technology.
For solving the problems of the technologies described above, design philosophy of the present invention is: between CD-ROM drive motor output shaft and work output shaft, increase power transmission shaft, and by power transmission shaft, make the integral position of work output shaft with respect to moving on handle.Its concrete technical scheme is as follows:
An electric tool, comprises casing handle, CD-ROM drive motor, work output shaft and power transmission shaft; CD-ROM drive motor is arranged in casing handle, and one end of power transmission shaft is connected with CD-ROM drive motor output shaft, and the other end of power transmission shaft is connected with output shaft; Described drive shaft axis is higher than CD-ROM drive motor output shaft axis and parallel.
Between power transmission shaft of the present invention and CD-ROM drive motor output shaft, by gear pair, be connected.Between power transmission shaft of the present invention and CD-ROM drive motor output shaft, adopt gear pair to be connected, its Main Function is in order to make power transmission shaft and CD-ROM drive motor output shaft can obtain a stable drive, the accurate kind of drive of gearratio; Also can reach reliable operation, efficiency is high, the life-span is long effect simultaneously; And the power of gear-driven use, transmission speed and size all can design arbitrarily as required.As preferably, the present invention preferentially adopts spur gear pair, no matter because spur gear pair is from machining angle or the on-the-spot angle of installing of using, be to be all conducive to most a kind of connected mode of the present invention.
Between power transmission shaft of the present invention and output shaft, by bevel-gear sett, be connected.The present invention adopts bevel-gear sett to be connected between power transmission shaft and output shaft, and its Main Function is that bevel-gear sett is a kind of moment of torsion transfer mode that direction changes that has of compactness, and bevel-gear sett is not very large to the tolerance of the axial location of power transmission shaft.
Work output shaft axis of the present invention is vertical with CD-ROM drive motor output shaft axis, and the stressed meeting of operator when grasping electronic work is more reasonable like this, also convenient operation more.
CD-ROM drive motor of the present invention is CD-ROM drive motor of the prior art, and the course of work that it is concrete and concrete mode of connection the present invention are not all described in detail.
The present invention is mainly used in grinding tool or saw instrument, compared with prior art, because the present invention increases power transmission shaft between CD-ROM drive motor output shaft and work output shaft, and by power transmission shaft, work output shaft is moved on the whole, electric tool is when work like this, may reduce the moment of torsion that working shaft rotation produces handle, make the reasonable stress of operator when grasping handle, be convenient to control, meanwhile, also can be so that electronic being operated in obtains the more free degree and better operation during processing work.
