As the core component for transmission in automated devices, the demand for motors is also increasing day by day.

[0003] In order to meet different application requirements, a motor with a reduction gearbox can reduce the speed, increase the torque, improve the running accuracy, reduce the noise, extend the service life, and at the same time avoid using transmission structures such as couplings, reducing the space occupation. In addition, by changing the output shaft direction of the reduction gearbox, the direction of force transmission can be changed.

[0004] At present, the fixing method of a motor with a reduction gearbox is mostly that screw holes are designed on the reduction gearbox or the motor body, and are connected and fixed through the holes of an external motor fixed seat with screws, which is rather inconvenient. It is necessary to drill holes on the external fixed seat according to the screw hole positions on the reduction gearbox or the motor body, and the operation is time-consuming and laborious.
