Abstract
The invention provides an electric tool which comprises a shell, a motor arranged in the shell and an output shaft and is provided with a flexible conduction system, wherein the flexible conduction system is driven by the motor, is connected with the output shaft and can be used for transmitting the torque of the motor to the output shaft. Since the flexible conduction system is flexible, the electric tool can be operated under a narrow environment.
Description
Technical field
The present invention relates to a kind of electric tool.
Background technology
Traditional electric tool such as screwdriver etc., has motor and the power transmission shaft that is connected with motor.These power transmission shafts are rigidity fully.The minimum dimension of power transmission shaft is also more than 10 centimetres.Add the size of electric tool self, almost about 20 centimetres.Such tool-face obviously is inefficient to the demand of the turn of the screw nail in about one 10 centimetres the gap.
Therefore, on the basis that prior art has been carried out concentrating on studies, the electric tool that the inventor provides a kind of small space to use.
Summary of the invention
The purpose of the invention is: a kind of maneuverable electric tool is provided.
For achieving the above object, the invention provides a kind of electric tool, comprise housing, be placed in motor, output shaft in the housing, described electric tool is provided with flexible conducting system, and described flexible conducting system is connected by motor-driven and with output shaft.
Compared with prior art, the present invention has following beneficial effect at least:
Flexible transmission system is flexible, therefore can in some narrow environment transmission of power be worked in output shaft, and the condition range that electric tool adapts to is wide.

100 electric tools, 32 blades, 44 outer tubes
1 housing, 4 flexible conducting system 45 torsion springs
2 motors, 41 pump housings, 47 bearings
3 working heads, 42 feed tubes
31 output shafts, 43 drain pipes
The specific embodiment
A kind of electric tool 100 comprises housing 1, is placed in motor 2, output shaft 31 in the housing 1, and electric tool 100 is provided with flexible conducting system 4, and flexible conducting system 4 is driven by motor 2 and is connected with output shaft 31.
Flexible conducting system 4 is driven by motor 2, and with transmission of power to output shaft 31.Because flexible conducting system 4 is flexible, therefore can pass through narrow space, so that electric tool 100 can adapt to narrow working condition.
In the first embodiment provided by the invention, flexible conducting system 4 comprises the pump housing 41 that is connected with motor 2, the feed tube 42 that is connected with the pump housing 41 and drain pipe 43, pivots working head 3, the circulation fluid of output shaft 31 are installed.Circulation fluid circulates between the pump housing 41, feed tube 42, drain pipe 43 and working head 3.Working head 3 is provided with the blade 32 that closely connects with feed tube 42 and drain pipe 43.Blade 32 rotates with the output shaft 31 coaxial driver output axles 31 that are connected.Circulation fluid constantly drives circulation fluid and enters from feed tube 42 under the driving of the pump housing 41, and promotes blade 32 rotations.After blade 32 was pushed a segment distance, circulation fluid was communicated with drain pipe 43, and circulation fluid enters drain pipe 43.Like this, motor 2 ceaselessly makes circulation fluid flow, and blade 32 is pushed and does not stop rotation.Do not stop to rotate and work with blade 32 coaxial 31 of the output shafts that are connected.Because feed tube 42 and drain pipe 43 are flexible bendables, so output shaft 31 can be by narrow space behavior on working face.
In the second embodiment provided by the invention, flexible conducting system 4 comprises flexible outer tube 44 and the torsion spring 45 that places in the outer tube 44.Torsion spring 45 1 ends are driven by motor 2, and the other end connects output shaft 31.Preferably, outer tube 44 is provided with running-on near the end of output shaft 31.Be provided with bearing in the running-on.Output shaft 31 passes in the middle of running-on, passes in bearing 47 simultaneously.Output shaft 31 relatively running-on rotates freely.Torsion spring 45 is fixed on the output shaft 31 near an end of output shaft 31.Because outer tube 44 and torsion spring 45 are flexible bendables, so output shaft 31 can be by narrow space behavior on working face.
