The invention discloses a wire clamp structure for a power transformation line, and relates to the technical field of wire clamp structures, in particular to the wire clamp structure for the power transformation line, which comprises a mounting plate, a fixed block, a turntable, a connecting block and a wire clamping device. The wire clamp structure for the power transformation line is provided. Through cooperation of the turntable, a movable plate, a reset spring, a limiting plug pin, a limiting hole, a sliding groove and a movable rod, and under the elastic force effect of the reset spring,the limiting plug pin can be inserted into the limiting hole to clamp the turntable, and prevention of turntable rotation is realized; when the angle of the wire clamping device needs to be adjusted,the movable rod is pulled to enable the limiting plug pin to move out of the limiting hole, the turntable is rotated, the wire clamping device is adjusted to a proper angle, then the movable rod is loosened, and the limiting plug pin is inserted into the corresponding limiting hole again to clamp the turntable, so that the angle of the power transformation line is adjusted, and the power transformation line is convenient to erect; the caliber of the wire clamping device can be adjusted through cooperation of a threaded rod, a threaded hole and a movable clamping ring, and the applicability ofthe device is improved.
