Before:The reduction shaft kit can be disassembled into nylon gear, shaft and one way needle bearing.
Now:The reduction gear kit is all in one which is not able to divide. Then there’s no one way needle bearing anymore.
After canceling the one-way bearing, the new design is all in one nylon gear which can bear greater torque with
external clutch.
The fixed reinforcing plate is optimized by adding embossing, depending on which the motor was better fixed even
without fixing block. Then the motor is fixed with double protection and avoid the cracking problem of overturning and
