Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9, a kind of electric wrench provided by the invention,
Including a circle or square drive disk 1, be rotatably assorted one drive shaft 2 and at least three of connection on the drive disk 1
Driven shaft 3, the drive shaft 2 are preferably square for square, triangle or other polymorphic structures, this programme.The driven shaft 3
For square, triangle or other polymorphic structures, this programme is preferably square, and the driven shaft 3 is arranged on is with the drive shaft 2
On the same circumference in the center of circle, and driven shaft 3 is evenly distributed on the circumference where it.
Connect by the first positioning ball 8 in the drive shaft 2 or a drive gear 4, the drive are connected by magnetism
The side of moving gear 4 is equipped with the square hole 4.1 coordinated with drive shaft 2.
When being connected in the drive shaft 2 with drive gear 4 by the first positioning ball 8：First is equipped with the drive shaft 2
Through hole 2.1, is equipped with the first positioning ball 8 in the first through hole 2.1, and the first positioning ball 8 passes through the first spring 10 and the
One screw 11 is fixed in the first through hole 2.1, and the centre of sphere of the first positioning ball 8 is located at the respective end of the drive shaft 2
Beyond face, that is, meet positioning and spacing requirement, and ensure that positioning ball will not fall off during dismounting.Drive shaft 2 axially distributed two
First positions ball 8 and not in sustained height, circumferentially sees, the first positioning ball 8 also not on same horizontal line, can so ensure
Dynamic coaxial degree when drive shaft 2 works with drive gear 4, is conducive to the stability of work, reduces noise.
