A step-by-step motor able to carry out up-and-down motion includes a housing, a bearing, a connecting member, a magnet, a rod unit, a right-handed coil, a reverse coil and a bayonet socket combined together. After the electric wires of the bayonet are electrically connected, the right-handed coil and the reverse coil respectively connected with the electric wires will be electrified to actuate the magnet and the connecting member to rotate clockwise or counter-clockwise. Simultaneously, the rod unit will be driven by the connecting member to move up or down linearly, able to carry out transmission effectively, small in size and taking less space.
