Preferably, the other end of the spring is fixedly connected to the wire clamping plate, and the wire clamping plate, the spring seat and the spring are symmetrically arranged on the inner wall of the wire outlet.

Preferably, the fastener comprises a bolt, the bolt penetrates through the box body from the outside and is arranged in the middle of the clamping plate, and the bolt is in threaded connection with the box body.

Preferably, the wire clamping plate is provided with an arc-shaped wire clamping hole for clamping and fixing a cable.

Preferably, the box body is further provided with an outer umbrella skirt and an inner umbrella skirt which play an insulating role, and two sides of the box body are provided with mounting seats for mounting and fixing the contact box.

Preferably, the outlet is arranged at the lower part of the box body.

Advantageous effects

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses in be equipped with the clamp plate at outlet inner wall symmetry, this clamp plate is fixed in the outlet inner wall through spring holder and spring, make this clamp plate have certain elasticity space, be fit for the cable of different specifications, be equipped with the wire clamping hole that plays clamping action to the cable on the clamp plate simultaneously, when the cable is worn out from this outlet, the cable joint is to this wire clamping hole, through screwing up the bolt this moment, make its power that produces the push down to the clamp plate compress tightly the clamp plate, the clamping action to the cable has further been realized, simultaneously because the design in wire clamping hole makes the cable difficult appearance damage under the tight power of clamp plate clamp.
