There is buckle, is equipped with and the card slot being clasped on the casing in the inside of the opening.
Further, the carbon brush component includes carbon brush, carbon brush holder, spring and pressing plate, and the casing is equipped with connection institute
The carbon brush holder mounting hole of opening and the casing internal is stated, the carbon brush holder is nested in the carbon brush holder mounting hole, the carbon
Brush be mounted in the carbon brush holder, the inner end of the carbon brush is supported with the commutator and is contacted, the outer end of the carbon brush with it is described
Cooperation is supported in spring inner end, and the outer spring end and the pressing plate support cooperation, and the pressing plate snaps onto the carbon brush holder installation
In the pressing plate caulking groove of outer end of hole.
Further, described pressing plate one end, which is equipped with, opens auxiliary handle, is additionally provided on the casing for the unlatching auxiliary handle
Built-in shrinkage pool.
Further, the carbon brush holder is rectangular frame structure, is respectively equipped in opposite two side walls to the spring
The arc positioning groove positioned.
Further, the carbon brush component has two, sets up the arranged on left and right sides in the commutator separately.
Compared with prior art, the utility model has the following beneficial effects:
The utility model is provided with the opening picked and placed for carbon brush, and opening in the position for corresponding to carbon brush component on casing
Snapping one has the cover board for opening attacker, therefore when needing replacing carbon brush, and the unlatching attacker on cover board need to be only agitated with finger,
Cover board can be opened and carbon brush is taken out and is replaced, without any tool in whole process, therefore be able to achieve the fast of carbon brush
Fast convenient changing, greatly improves work efficiency whereby, convenient for users to use.Simultaneously as opening attacker is built in machine
In the groove of shell surface programming, therefore the mistake opening operation being also possible to prevent in product use process, structure are reliable and practical.

Specific embodiment
The embodiment provided with reference to the accompanying drawing is described in further detail the utility model.
As shown in Figures 1 to 7, one kind described in the present embodiment can convenient changing carbon brush electric hand drill, including casing 1 and set
Motor 2, commutator 3 and carbon brush component 4 in casing 1 are set, the position that carbon brush component 4 is corresponded on casing 1 is equipped with opening
11, cover board 5 is snapped at opening 11, and cover board 5, which is equipped with, opens attacker 51, corresponds on casing 1 and opens the position of attacker 51 and set
Have for opening the built-in groove 12 of attacker 51.When needing replacing carbon brush, the unlatching attacker 51 on cover board 5 is agitated with finger, first
Cover board 5 is opened, then taking out carbon brush component 4 is replaceable carbon brush.
One end end that attacker 51 is specifically located at cover board 5 is opened, the other end end of cover board 5 is equipped with buckle 52, casing 1
On in the inside of opening 11 be equipped with the card slot 16 that cooperates with buckle 52.
Carbon brush component 4 includes carbon brush 41, carbon brush holder 42, spring 43 and pressing plate 44, and casing 1 is equipped with connection opening 11 and machine
Carbon brush holder mounting hole 13 inside shell 1, carbon brush holder 42 are nested in carbon brush holder mounting hole 13, and carbon brush 41 is mounted on carbon brush holder 42
Interior, the inner end of carbon brush 41 is supported with commutator 3 to be contacted, and cooperation, 43 outer end of spring are supported in the outer end and 43 inner end of spring of carbon brush 41
