In actual operation, the operator can pass one end of the bone plate through the first bending hole 51 and the other end of the bone plate through the second bending hole 61, and then rotate the first extension rod 5 and the second extension rod 6 at the same time, so that the two ends of the bone plate are bent, so that the cross-section of the bone plate is arc-shaped, which is convenient for the bone plate to fit the contour of the bone.
[0033] like Figure 1 and 2As shown, the first handle 1 is rotatably connected to the inner side of the top end thereof, and the second handle 2 is rotatably connected to the inner side of the top end thereof. The first adjusting knob 3 and the first bending wheel 31 are coaxially rotatably connected on the inner side of the hinge shaft of the first handle 1 and the second handle 2. The first adjusting knob 3 and the first bending wheel 31 are integrally formed, and the first adjusting knob 3 is provided with a first anti-slip groove 34. A first gap 33 is formed between the first rotating wheel 11, the second rotating wheel 21 and the first bending wheel 31, and the first gap 33 is for placing the bone plate. The outer peripheral surface of the first bending wheel 31 is provided with first arc surfaces 32 of different arcs, and there are three first arc surfaces 32, and the diameters of the three first arc surfaces 32 are 6.7 mm, 9.0 mm and 12.0 mm respectively.
