The limiting strip is also used to limit the limiting rod to prevent the limiting block from moving inward under the action of the spring during disassembly.

[0003] However, this device absorbs the heat on the surface of the motor through the heat conduction sheet and conducts it into the external air. This method takes a long time and has a slow heat dissipation efficiency, and the range of external air contacted by the heat conduction sheet is limited, so that there may still be a certain amount of heat inside that cannot be well conducted out. When the motor is continuously driven, the heat that cannot be conducted out in time in the heat conduction sheet accumulates more and more, which reduces the heat dissipation efficiency of the device to a certain extent and is likely to have a certain impact on the operation of the motor.
