MANUAL OPERATION MECHANISM HANDLE FOR CIRCUIT BREAKER

Disclosed is a manual operation mechanism handle for a circuit breaker, the handle comprising an operation handgrip (15), a lock-up device (12), and a locking shaft (14), wherein the middle of the lock-up device (12) is pivotally arranged on the operation handgrip (15), a front end of the lock-up device (12) is connected to the locking shaft (14), the lock-up device (12) is connected to the operation handgrip (15) by means of a first driving member, a rear end of the lock-up device (12) cooperates with a locking mechanism in limiting manner, the rear end of the lock-up device (12) is provided with a lock-up hole (21), and the lock-up hole (21) is blocked by the operation handgrip (15). When the circuit breaker is in a opened state, the locking mechanism is unlocked, the first driving member enables the front end of the lock-up device (12) to move down to drive the locking shaft (14) to lock the operation handgrip (15), and at the same time, the rear end of the lock-up device (12) is raised, such that the lock-up hole (21) is released from the operation handgrip (15). The locking mechanism can realize locking of the lock-up device (12), and a user can conveniently rotate the operation handgrip (15), such that after the locking mechanism is unlocked by means of the opening/closing of the circuit breaker, the lock-up device (12) can automatically drive the locking shaft (14) to lock the operation handgrip (15). La invención se refiere al campo de electrodomésticos de bajo voltaje, y más particularmente, a una agarradera de un mecanismo de operación manual de un interruptor de circuito, el cual incluye una agarradera operativa, un dispositivo de candado, y un eje de enclavamiento, en el que una parte intermedia del dispositivo de candado se coloca oscilantemente sobre la agarradera operativa, un extremo frontal del dispositivo de candado se conecta al eje de enclavamiento, el dispositivo de candado se conecta a la agarradera operativa a través de un primer elemento de accionamiento, un extremo posterior del dispositivo de candado se encuentra en ajuste de límite con un mecanismo de enclavamiento, un orificio de candado se coloca en el extremo posterior del dispositivo de candado, y el orificio de candado es blindado por la agarradera operativa; cuando el interruptor de circuito se encuentra en un estado apagado, el mecanismo de enclavamiento se desbloquea, el primer elemento de accionamiento hace que el extremo frontal del dispositivo de candado se suma para a
