Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
It is the structure inside clear expression electric drill referring to Fig. 1-3, it is necessary to illustrate, in Fig. 3, part brush, which covers, not to be shown.
A kind of electric drill for being convenient for changing brush, including：Casing 1, brush holder 2, brush spring 5, brush 4 and threaded connector 3.
Wherein：
Casing 1 is made up of the left housing 11 and right shell 12 for mutually fastening and collectively constituting element receiving space.
Brush holder 2 is connected through a screw thread part 3 and is fixed on casing 1.
Brush 4 is installed on brush holder 2.
The pressure of brush spring 5 is on brush 4.
Casing 1 is provided with the opening for being used for changing brush 4, and casing 1 also includes the brush lid 122 coordinated with opening.
Brush spring 5 is disc spring.
