Busbar bending position indicator

The invention relates to position indicators, in particular to a busbar bending position indicator. The busbar bending position indicator comprises an I-shaped spool (2), an M line (4), an N line (5), spiral springs (6) and a bearing (9). The I-shaped spool comprises a first side plate (7), a second side plate (8) and a hollow cylinder arranged between the first side plate and the second side plate. Angle scale marks (3) are arranged on the plate surface of the first side plate or the second side plate. The spiral springs are arranged at the two ends in the hollow cylinder respectively. The bearing is arranged between the two spiral springs. One end of the M line and one end of the N line are connected with the two spiral springs respectively, and the other end of the M line and the other end of the N line are arranged outside the hollow cylinder. According to the busbar bending position indicator, the two spiral springs are arranged in the I-shaped spool and control the M line and the N line respectively, and the number of degrees is obtained through the scale mark corresponding to the angle between the M line and the N line which are drawn out, so that the purpose of rapidly and accurately measuring the angle between two wire clamps is achieved.
