The invention discloses a wiring tool for transformer detection, which comprises an outer shell body, wherein a servo motor base is arranged at the bottom part inside the outer shell body; the upper end of the servo motor base is connected with a servo motor; one end, away from the servo motor base, of the servo motor is connected with a coupler; one end, away from the servo motor, of the coupleris connected with a threaded rod; the servo motor is connected with the threaded rod by means of the coupler; and one end, away from the coupler, of the threaded rod is fixedly connected with a threaded rod rotating baffle plate. The wiring tool can better control the rotation precision of a No. 2 fixing plate through setting the servo motor to drive a linkage rod to control a rotating angle of the No. 2 fixing plate, avoids the trouble that repeated manual adjustment is required, and can clamp a transformer to be detected more quickly and conveniently through driving movable clamping plates to move by means of a servo motor push cylinder; and the structure of the adopted mechanism is simple, the usage and operation are convenient, and the operating efficiency of the wiring tool for transformer detection is greatly improved.
