The support frame 3 is connected to the planetary gear set mechanism 1 through a bolt structure with a model of M10*1.5. The planetary gear set mechanism 1 includes an internal gear 11, a first planetary gear 12, a second planetary gear 13, a third planetary gear 14 and a main gear 15, and the first planetary gear 12, the second planetary gear 13 and the third planetary gear 14 are respectively meshed with the internal gear 11 and the main gear 15. The fixed support structure 2 includes a fixed plate 21, a first fixed block 22, a second fixed block 23, a third fixed block 24, a rotating shaft 25 and a force block 26; the fixed plate 21 is connected to the first planetary gear 12, the second planetary gear 13, the third planetary gear 14 and the main gear 15 through the first fixed shaft 122, the second fixed shaft 132, the third fixed shaft 142 and the rotating shaft 25 respectively; the first fixed block 22 is connected to the fixed plate 21, the second fixed block 23 and the third fixed block 24 are vertically connected to the first fixed block 22, and the steel material 5 to be bent is fixed between the first fixed block 22, the second fixed block 23 and the third fixed block 24; the rotating shaft 25 is connected to the motor 4, and the force block 26 is fixed on the rotating shaft 25. A blocking device 111 for bearing the bending force of the steel material 5 to be bent is provided at the edge of the inner gear 11, and the shape of the blocking device 111 is set to be a cuboid.
