Technique effect of the present utility model is:

1. bulb separation pin and bulb separation needle stand are resolved in bulb separation mechanism, and the bulb separation pin is assemblied on the bulb separation needle stand, and manufacturing and installation are easily.

2. adding shock mount on the bulb separation pin, become flexible structure by original rigid construction, adopt the elastic force of spring that the bulb separation pin is risen, is not that hard squeezing driven steel ball, can not cause damage to steel ball.

3. also add shock mount on the thimble, when the bulb separation pin was subjected to excessive resistance, this spring shrank, and avoids the bending of bulb separation pin.

4. increased bearing deformation mechanism, made bearing outer ring produce micro-strain, steel ball can freely roll in raceway, and the bulb separation pin can be not stuck, improved bulb separation efficient.
