Abstract
The utility model discloses an electric wrench, which comprises a casing and a motor, a bearing, a reversing bearing and a rotating shaft sequentially connected and arranged in the casing, wherein a gear shaft is arranged on the extending part of one end of the motor, the gear shaft connects with the reversing bearing, one end of the reversing bearing is connected to the rotating shaft via a small bearing, and a twelve point socket is sleeved on the rotating shaft. The electric wrench is labour-saving and time-saving, and is large in torque, easy for operation and especially suitable for maintaining cars.
Description
Technical field
The utility model relates to a kind of electric tool, relates in particular to a kind of electric wrench.
Background technology
Current, kart such as family-sized car are more and more, requirement to the important maintenance tool spanner of car is also more and more higher, nowadays the general ordinary people of the spanner in the market clumsy and effort of comparison that operates, especially personages such as city working clan and various brain workers turn on or tighten the screw of automobile with regard to more difficult use common wrench.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 electric wrench a kind of easy to operate, time saving and energy saving, controllable torque 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.
The material that described housing adopts is engineering plastics.
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, a kind of electric wrench of the utility model, 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.The utility model electric wrench, the material that described housing 1 adopts is engineering plastics.
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.
