The utility model relates to an assisting device, in particular to a busbar bending assisting device and belongs to the technical field of power distribution equipment. The busbar bending assisting device comprises a bottom plate, a lifting adjusting baseplate and a horizontal adjusting baseplate are sequentially fixed on an upper portion of the bottom plate from left to right, and a lifting screw is mounted inside the lifting adjusting baseplate via a bearing support. A middle portion of the lifting screw is connected with a lifting adjusting nut in a threaded manner, a lifting adjusting plate is connected onto the lifting adjusting nut, a lifting clamping plate is connected to the front end of the lifting adjusting plate, a support plate is connected to the lower end of the lifting clamping plate, a horizontal adjusting nut is arranged at the upper end of the horizontal adjusting baseplate, a horizontal screw is connected into the horizontal adjusting nut in a threaded manner, and one end, facing the lifting clamping plate, of the horizontal screw is connected with a horizontal clamping plate. The busbar bending assisting device is capable of clamping and adjusting a busbar and carrying the busbar to move smoothly during bending. The busbar bending assisting device has the advantages that the height of the busbar can be adjusted flexibly, a worker is facilitated to determine a bending position quickly, bending efficiency is improved and a one-time bending rate is increased.
