In order to achieve the above object, the utility model provides a following technical scheme: strain clamp, including the winding displacement seat, the both sides of winding displacement seat are provided with the extension board, the embedding has built-in cover on the extension board, it has the U-shaped frame to pass in the built-in cover, it is protruding to be provided with the screw thread on the U-shaped frame, the screw thread is provided with the nut on the screw thread arch.

Preferably, the cross-sectional areas of the two side rods of the U-shaped frame are circular, the U-shaped frame is fixedly connected with a wire clamping seat, the wire clamping seat is arranged in the wire arranging seat, and the wire arranging seat is provided with an inner arc surface.

Preferably, the wire arranging seat is welded with two rings through a support, and the two rings are respectively arranged on two sides of the upper end face of the wire arranging seat.

Preferably, the wire arranging seat is welded with a connecting plate, a curved plate is arranged on the connecting plate, and a threaded hole is formed in the curved plate.

Preferably, the lower end of the connecting plate is provided with a mounting seat with a trapezoidal structure, and the mounting seat is provided with a wire arrangement groove.

Compared with the prior art, the beneficial effects of the utility model are that: this strain clamp: 1. the U-shaped frame moves up and down, the locking effect of the nut is matched, and the wire clamping seat enters the wire arranging seat to support the connecting wire tightly, so that the fastening effect of the connecting wire is realized;

2. the connection wire is bent downwards and led out through the wire arranging groove with a certain inclination angle, and the bent part has a supporting and protecting effect.
