Property.
Wherein, brush includes brush carrier, and brush is connected and fixed with brush carrier；End cap is equipped with fixing groove, brush and brush
Frame is fixed in fixing groove.
Prevent brush from moving so that brush and brush carrier fixation are more stable by the setting of fixing groove.
Wherein, brush carrier is equipped with protrusion, and brush is equipped with via hole corresponding with protrusion, and protrusion is stretched out from via hole to be realized
It is fixed.
Protrusion is stretched out from through-hole, so that bonding strength is higher, prevents from falling off in use.
Wherein, protrusion is with brush by being welded and fixed.
By the way of being welded and fixed, so that whole fixing intensity improves, prevent from falling off in use.
Wherein, protrusion is equipped with extension, and fixing groove side is equipped with the notch being adapted to extension.
Extension is specially the part that protrusion is pierced by via hole, the setting of notch, so that brush and brush carrier are preferably real
It now installs, guarantees the use of installation.
Wherein, brush is made of silver palladium alloy.
Using the setting of silver palladium alloy, so that the electric conductivity of brush itself improves, power consumption is reduced, and increases service efficiency.
Wherein, end cap is made of ABS plastic.
End cap is made of ABS plastic, so that end cap integral strength improves.
