Abstract
The invention provides a handle with a safe locking device and a circuit breaker comprising the handle. The handle is used for driving a dynamic contact of a switch device to rotate between a switching-on position and a switching-off position relative to a static contact. The static contact is fixed in the housing of the switch device. The handle comprises the components of: a handle base, a connecting mechanism which has one end that is fixedly connected with the dynamic contact and the other end that is connected with the handle base for transmitting torque, and a locking mechanism which is used for locking the handle base and the connecting mechanism at the switching-on position or the switching-off position in a normal operation state of the switch device. The connecting mechanism is connected with the handle base in a manner that rotation of the handle base leads to relative rotation between the connecting mechanism and the handle base based on increase of a separating resistance in an abnormal operation state that separation between the dynamic contact and the static contact is difficult. Therefore, when the handle base rotates to the switching-off position, the connecting mechanism is arranged at a deviated position which deviates from the switching-off position, thereby ensuring incapability of locking the handle base relative to the connecting mechanism at the switching-off position.
