The invention discloses a transmission speed change device, which comprises a reciprocating gear, a right-shift half gear, a left-shift half gear, and an input gear. The input gear is meshed with a right-shift input gear; the right-shift input gear and the right-shift half gear are fixed on a right-shift input shaft; the right-shift half gear is meshed with the reciprocating gear; the reciprocating gear is meshed with the left-shift half gear; the left-shift half gear and a left-shift input gear are fixed on a left-shift input shaft; the left-shift input gear is meshed with an idler wheel; and the idler wheel is meshed with the input gear. The right-shift half gear and the left-shift half gear are same in size, have a toothed radian of 180 DEG, have a phase difference of 180 DEG and are not simultaneously meshed with the reciprocating gear; the right-shift input gear and the left-shift input gear are same in type; and the input gear and the idle wheel are same in type. The transmission speed change device has
