[0029] The multi-section clamping unit includes a first movable plate 12; a first connecting pin 13 is inserted into a hole at the upper end of the first movable plate 12; a second movable plate 14 is sleeved on the first connecting pin 13; a second connecting pin 17 is inserted into the upper end of the second movable plate 14; a third movable plate 18 is sleeved on the second connecting pin 17; a third connecting pin 20 is inserted into the upper end of the third movable plate 18; a first spring 15 is fixedly connected between the first movable plate 12 and the second movable plate 14; a second spring 19 is fixedly connected between the second movable plate 14 and the third movable plate 18; when working, the first spring 15 elastically supports the first movable plate 12 and the second movable plate 14, and the second spring 19 elastically supports the second movable plate 14 and the third movable plate 18, and cooperates with the elastic rotating unit to make the first movable plate 12, the second movable plate 14 and the third movable plate 18 be able to move. The plate 14 and the third movable plate 18 are in a straight line when not under force, and are perpendicular to the bending handle 2.
