An angle line clamping device tool comprises an original line clamping device, supporting connecting sheets, a tension connecting sheet, pins and a U-shaped pull ring. According to the utility model, a pair of connecting sheets is added at each of the two ends of the tension connecting sheet (3A) of the original line clamping device to form a triangle structure, wherein one pair is supporting connecting sheets B(3B), and the other pair is tension connecting sheets (6); the tension connecting sheet (3A) of the original line clamping device becomes the supporting connecting sheet A(3A), and the U-shaped pull ring (4) is arranged at the connection position of the supporting connecting sheet B(3B) and the tension connecting sheet (6), and is fixed by the pins (5) of the original line clamping device. The angle line clamping device tool of the utility model enables the working time to be shortened, the working efficiency to be improved and the work safety risk to be reduced.
