Post；The output end cap is provided with some screw thread via A around axle center annular array, and the end face A is set around axle center annular array
There are some screwed hole Bs corresponding with screw thread via A.
Preferably, the blind hole A and screwed hole B interval settings.
Compared with prior art, a kind of structure improved miniature gears case described in the utility model, output end cap passes through
Screw and protection cage connection, have shortened the length of screw, so as to increase the intensity that screw bears peripheral force, protection shell with it is defeated
Enter end cap threaded connection, bonding strength when enhancing motor and gear-box are connected, and motor is driven with three-stage planetary gear
Primary planet pinion in mechanism smooth can be engaged, simple and convenient assembly.
