In this embodiment, through the arrangement of the connecting groove 63 and the horn protrusion 45, the transmission member 6 is separated from the locking tongue 41, which reduces the movement of the locking tongue 41 and drives the transmission member 6 to move. The space reduces the volume of the housing 3 and increases the utilization efficiency of the space inside the housing 3; at the same time, in the current state, the lever principle of using the rotating shaft of the buckling part as the fulcrum reduces the effect of the transmission element on the crankshaft force.

According to another embodiment provided by the present invention, as shown in Figs. 2 to 4, a trip unit. The difference between this embodiment and the second embodiment lies in the specific structure of the crankshaft 7.

On the basis of the second embodiment, in this embodiment, the crankshaft 7 includes:

The axis of the rotating disc 71 is perpendicular to the axis of the rotating shaft 42, and the rotating disc 71 is rotatably arranged in the housing 3 along the axis direction, that is, the axis of the rotating disc 71 is arranged horizontally.

The toggle block 72 is arranged at the outer end of the rotating disk 71 and rotates along the axis of the rotating disk 71; the toggle block 72 moves to a specific position to limit the transmission member 6 so that the lock tongue 41 is held in Locking position; therefore, when the rotating disc 71 rotates and drives the toggle block 72 to move to the lower end, the toggle block 72 can abut on the transmission member 6, or the distance between the toggle block 72 and the transmission member 6 is small, and the toggle The block 72 can be located at a specific position, and realizes the function of limiting the transmission member 6.
