The utility model has the advantages of large torsion force, timesaving and laborsaving, convenient operation which can be widely used in vehicle maintenance.
Description
Technical field
The utility model relates to a kind of electric tool, relates in particular to a kind of electric wrench.
Background technology
At present, private car is more and more, and is also more and more higher for the requirement of the important maintenance tool spanner of private car, the gas that gets up relatively to require great effort of the spanner general operation in market nowadays, women driver particularly turns on or tightens the screw of automobile with regard to more difficult use spanner.Therefore be badly in need of occurring a kind of easy to operate, time saving and energy saving electric wrench on the market.
Summary of the invention
The technical problem that the utility model solved is the defective that overcomes prior art, and a kind of easy to operate, time saving and energy saving Controllable Torque Electric-driving Wrench is provided.
The utility model provides a kind of electric wrench, comprise housing and be arranged on motor, bearing, reversing bearing and the rotating shaft that connects successively in the described housing, wherein an end extension of motor is provided with the tooth axle, described tooth axle is connected with described reversing bearing, one end of described reversing bearing is connected with described rotating shaft by a little bearing, is socketed with coupling box in described rotating shaft.
Coupling box wherein can adopt various models, to be suitable for the screw of various models up and down.
As a kind of improvement of the present utility model, in described reversing bearing, be provided with a clutch, described clutch comprises that but two are parallel to each other and the parallel block of clutch, be provided with steady pin and steel ball in the described parallel block, steel ball produces motive force to steady pin during rotation under action of centrifugal force, its effect is to regulate centrifugal force, to reach the purpose of adjusting knob distance, reach the rotating speed of setting when the driven by motor reversing bearing, make the parallel block phase clutch of the built-in symmetry of reversing bearing, rotate, put coupling box at the end of rotating shaft thereby drive output revolving shaft, thereby easily save time the laborsaving screw of just tightening or outward winding.
As another kind of improvement the of the present utility model, described motor is two-way electric rotating machine, and described two-way electric rotating machine is connected with a two-way gauge tap.Pressing the two-way switch upper motor is the clockwise direction rotation, and the Push switch lower motor is counterclockwise rotated, and makes that operation is easier.
Front end at described housing also is provided with indicator lamp.
Owing to adopt above-mentioned technical scheme, the utlity model has following beneficial effect:
1, improved the torque forces of spanner;
2, make the operator time saving and energy saving;
3, easy and simple to handle.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment is illustrated.
As shown in Figures 1 to 4, the utility model electric wrench, comprise housing 1 and be arranged on motor 2, bearing 3, reversing bearing 4 and the rotating shaft 6 that connects successively in the housing 1, wherein an end extension of motor 2 is provided with tooth axle 9, tooth axle 9 is connected with reversing bearing 4, one end of reversing bearing 4 is connected with rotating shaft 6 by a little bearing 5, is socketed with coupling box 7 in rotating shaft 6.Coupling box 7 wherein can adopt various models, to be suitable for the screw of various models up and down.
In described reversing bearing 4, be provided with a clutch, clutch comprises that but two are parallel to each other and the parallel block 13 of clutch, be provided with steady pin and steel ball 14 in the parallel block 13, steel ball 14 produces motive force to steady pin during rotation under action of centrifugal force, its effect is to regulate centrifugal force, to reach the purpose of adjusting knob distance, reach the rotating speed of setting when the driven by motor reversing bearing, make the parallel block 13 phase clutches of reversing bearing 4 built-in symmetries, rotate thereby drive output revolving shaft 6, put coupling box 7 at the end of rotating shaft 6, thereby easily save time, the laborsaving screw of just tightening or outward winding has been realized the function of electric wrench.
Wherein, motor 2 adopts two-way electric rotating machine, and this two-way electric rotating machine is connected with a two-way gauge tap 8.Pressing two-way switch 8 upper motor is the clockwise direction rotation, and the Push switch lower motor is counterclockwise rotated, and makes that operation is easier.
In use, be connected energising with power supply 10 energising or with electricity folder 11 with automobile storage battery, pull two-way switch 8, motor rotation to a direction, when motor reaches certain rotating speed, the parallel block of the built-in symmetry of reversing bearing rotates thereby drive output revolving shaft 6 by the mutual fit of centrifugal force, and then drives coupling box 7 rotations of the terminal socket of rotating shaft 6, when needs rotating shaft 6 backward rotation, pull two-way switch to another direction, the motor antiport is realized rotating shaft 6 backward rotation.Front end at housing 1 also is provided with indicator lamp 12.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
