The invention belongs to the field of transmission technology, particularly relates to a multi-unit collinear driving transmission which comprises an input shaft, a fixed rod, a pressing spring, a dynamic circular plate and a driving unit, wherein the input shaft is mounted on the fixed rod and the input shaft transmits energy to a telescopic shell of the input shaft as a driving shaft. An inner ring gear in the driving unit meshes with a sliding gear through a middle gear and a switching sliding ring drives a transmission shaft to move along a sliding shaft by a first clamp ring and a second clamp ring. When one end of the transmission shaft stretches out from a supporting ring of the inner ring gear, the anterior circular plate drives the transmission shaft to rotate and the transmission shaft is in the same rotating speed with the anterior circular plate this moment. The switched sliding ring is controlled to enable the transmission shaft not to stretch out of the supporting ring of the inner ring gear, at the moment the anterior circular plate is in contact friction with the end surface of the supporting ring of the inner ring gear, accordingly, the inner ring gear is driven, the sliding gear is driven to rotate by the inner ring gear and the transmission shaft is driven to rotate by the sliding gear. Then, the rotating speeds of the transmission shaft and the anterior plate change and the transmission purpose is achieved. The multi-unit collinear driving transmission provides higher use value.
