Power supply machine output shaft 2 stretches out and the via 8 with motor output shaft 2 close-fitting.In the present embodiment, because under described motor output shaft
It is additionally provided with a guide post 10 on the motor body 3 of end, therefore the upper surface of protective cover 6 is additionally provided with the small vias passing through for guide post 10
11.
As the improvement project of the present embodiment, also set between described protective cover 6 and motor output shaft lower end motor body 3
There is a cushion 9, certain cushion 9 also is provided with the hole that power supply machine output shaft 2 and guide post 10 pass through.
As the preferred version of the present embodiment, described protective cover 6 is plastic safety cover, and plastic safety cover passes through to be molded into
Type, low cost and easy to process, can be mass.
In the present embodiment, also form an inclined plane 6.1 between the described upper surface of protective cover 6 and bottom, this inclines
The setting on inclined-plane 6.1 is it is easier to throwing away of water.
