The invention provides a rotary positioning device, which comprises a first seat body with a first limiting part, a second seat body rotatably arranged on the first seat body and rotating to a first state in the forward direction and rotating to a second state in the reverse direction, a first elastic device used for driving the second seat body to rotate in the forward direction, a locking piece rotatably arranged on the second seat body and rotating forwards to a locking state and rotating reversely to an unlocking state, and a second elastic device; when the second seat body is in the second state, the second elastic device can drive the locking piece to rotate in the forward direction, and the locking piece in the locking state abuts against the first limiting part so that forward rotation of the second seat body can be limited; the locking piece can be driven by an external force to reversely rotate to the unlocking state to be staggered from the first limiting part; the rotary positioning device is ingenious in structure, and operation and use are effectively facilitated. The invention further provides a bicycle generator comprising the rotary positioning device, and the bicycle generator can be effectively and conveniently operated and used.

    本发明提供了一种旋转定位装置,包括:第一座体,其上设置有第一限位部;第二座体,可转动设置在第一座体上而可正向转动至一第一状态和反向转动至一第二状态;第一弹性装置,用于驱动第二座体正向转动;锁定件,可转动设置在第二座体上而可正向转动至一锁定状态和反向转动至一解锁状态;第二弹性装置;第二座体处于第二状态时,第二弹性装置可驱动锁定件正向转动,锁定状态下的锁定件与第一限位部抵接而可限制第二座体的正向转动;锁定件可由外力驱动而反向转动至解锁状态而与第一限位部错开,该旋转定位装置结构巧妙,有效方便了操作和使用。本发明还提供了一种包含有该旋转定位装置的自行车发电机,能够有效方便操作和使用。
