Clamping part and wiring device

The utility model relates to the field of electric measurement and measurement and the technical field of relay protection, and discloses a clamping part and a wiring device. Wherein the clamping part is made of a conductive material and comprises a cross arm, a first clamping arm and a second clamping arm which are respectively arranged at the two ends of the cross arm, and a first hook part and a second hook part which are respectively arranged at the tail ends of the first clamping arm and the second clamping arm; the first hook part and the second hook part are oppositely arranged and tend to clamp inwards. According to the technical scheme, during wiring, only the clamping part needs to face the screw and exert pressure, the first hook part and the second hook part which have elasticity can generate certain deformation, so that the head of the screw is allowed to enter the clamping part and clamp the head of the screw, and wiring work is completed. Compared with the prior art, the clamping part does not
