At this time, the first gear 5 is clamped with the second gear 6.

[0030] On the basis of the first embodiment, in order to prevent the servo driver body 7 from affecting the heat dissipation of the motor body 1 when it is placed on the surface of the motor body 1, a mounting rod 20 is provided on the surface of the motor body 1, and the mounting rod 20 is movably connected to the motor body 1. A fan blade 2 is fixed on the surface of the mounting rod 20, and a transmission belt 3 is provided on the surface of the mounting rod 20.

When the limit groove 12 below the guide rod 10 corresponds to the limit block 13, the push plate 18 is stopped. Due to the elasticity of the spring 14, the spring 14 resets and pushes the baffle 19 to clamp the limit block 13 in the limit groove 12.
