Abstract
The utility model discloses an electric wrench, which comprises a casing, a motor, a bearing, an inverting bearing and a rotating shaft. The motor, the bearing, the inverting bearing and the rotating shaft are arranged inside the casing and are successively connected with each other. The extension part at one end of the motor is equipped with a tooth axle. The tooth axle is connected with the inverting bearing. One end of the inverting bearing is connected with the rotating shaft through a small bearing. A quincuncial socket is sleeved on the rotating shaft. The casing is made of toughening plastic material. The electric wrench has the advantages of large torsion force, time saving, labor saving and convenient operation and is very suitable for the maintenance of vehicles.
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 increasingly high; Nowadays operate comparison clumsy and effort, especially personages such as city working clan and various brain workers of the general ordinary people of the spanner in market 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; Said tooth axle is connected with described reversing bearing, and an end of said reversing bearing is connected with said rotating shaft through a little bearing, in said rotating shaft, is socketed with coupling box.
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 utility model, in described reversing bearing, be provided with a clutch, but described clutch comprises that 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, and its effect is to regulate centrifugal force; Reaching the purpose of adjusting knob distance, when the driven by motor reversing bearing reaches the rotating speed of setting, make the parallel block phase clutch of the built-in symmetry of reversing bearing; Thereby driving output revolving shaft rotates; End in rotating shaft puts coupling box, thereby easily saves time, the laborsaving screw of just tightening or outward winding.
The material that described housing adopts is a toughened plastic.
Another kind as the utility model improves, and described motor is two-way electric rotating machine, and described two-way electric rotating machine is connected with a two-way switch.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 explained.
Extremely shown in Figure 4 like Fig. 1; 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, and tooth axle 9 is connected with reversing bearing 4; One end of reversing bearing 4 is connected with rotating shaft 6 through a little bearing 5, in rotating shaft 6, is socketed with coupling box 7.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, but clutch comprises that two are parallel to each other and the parallel block 13 of clutch, are 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, and its effect is to regulate centrifugal force, to reach the purpose of adjusting knob distance; When the driven by motor reversing bearing reaches the rotating speed of setting, make the parallel block 13 phase clutches of reversing bearing 4 built-in symmetries, rotate thereby drive output revolving shaft 6; End in rotating shaft 6 puts coupling box 7; 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 switch 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 a toughened plastic.
In use, be connected energising with automobile storage battery, pull two-way switch 8 to a direction with power supply 10 energising or with electricity folder 11; Motor rotation, when motor reached certain rotating speed, the parallel block of the built-in symmetry of reversing bearing was through the mutual fit of centrifugal force; Rotate thereby drive output revolving shaft 6, and then drive 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.
