When the detector 9 is used in daily conditions, the electromagnet 904 always receives current from the connecting bar 809 and attracts the magnetic block 903, that is, the deflection column 902 always clamps the limiter 2, so that the pressing column 305 cannot easily slide down.

The limiter 2 comprises a driving wheel 201 connected with the inner wall of an ann clamping cover 901, a limiting strip 202 connected with a lower pressing column 305 is connected to the outer wall of one side of the driving wheel 201 in a meshed mode, a clamping block 203 clamped by a deflection column 902 is installed on one side, away from the driving wheel 201, of the limiting strip 202, a manual strip 204 penetrating through a top cover 101 to the outer side is connected to the outer wall of the other side of the driving wheel 201 in a meshed mode, and a fusing column 205 (selectable fuse) electrically connected with an electromagnet 904 is installed on one side, away from the driving wheel 201, of the manual strip 204.

Once the live wire and the zero wire are short-circuited, current cannot pass through the electromagnet 904, the electromagnet 904 does not generate magnetic force to suck the magnetic block 903, at the moment, the torsion spring in the deflection column 902 can play a role, the deflection column 902 rotates counterclockwise, then the clamping block 203 on the limiting strip 202 is not limited, namely, the pressing column 305 is released, at the moment, the pressing column 305 descends to drive the limiting strip 202 to move together, at the moment, the movable limiting strip 202 can be meshed with the driving wheel 201 to rotate clockwise (taking fig. 1 as an example), and when the driving wheel 201 rotates, the manual strip 204 can move in the opposite direction of the limiting strip 202, so that the manual strip slides out of the top cover 101 to facilitate maintenance of a user and further warning.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
