Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
As shown in Figure 1, Figure 2 and Fig. 3, starter casing of the present utility model and brush holder location structure, including casing 1, bonnet 2,
Brush holder 3 and Driving terminal 4.
Driving terminal 4 is semi-surrounding structure, be provided with electromagnetic switch 6 on drive shaft 5, Driving terminal 4 to hold and support,
The control stick of electromagnetic switch 6 is connected by shift fork 61 with drive shaft 5, and drive shaft 5 is provided with the shaft shoulder 51 and back-up ring 52, passes through the shaft shoulder
51 and back-up ring 52 formation position limiting structure, limitation starter in isolator ejected position.Back-up ring 52 passes through lock washer and screw
The front end of drive shaft 5 is fixed on, front end is provided with dust cap 53, plays dustproof effect, bonnet 2 passes through fastening bolt and brush holder 3 and machine
Shell 1 is fastenedly connected.
Casing 1 is provided with seam 11, and the fixed plate of brush holder 3 is provided with the first boss 31 being adapted with seam 11, first
