Stably-mounted fingertip gyroscope

The utility model relates to the field of fingertip spinner toys, in particular to a fingertip spinner stable in installation, which comprises a rotor part, a bearing and a stator part. During installation, the outer ring of the bearing is erected on the upper surface of the supporting ring piece, the bearing is fixed to the rotor part, then the lower stator penetrates through the supporting ring piece to be inserted into the inner ring of the bearing, the bottom end of the upper stator is inserted into the connecting groove from the through hole, and the fixing pin is stressed to move upwards along the installation hole in the process. And the bottom surface of the external threaded rod is always in contact with the hole surface of the internal threaded hole, and then the external threaded rod on the fixed pin is screwed into the internal threaded hole by rotating the rotating part at the top end of the fixed pin, so that the lower stator and the upper stator are stably connected, and the stator part is stab
