The utility model relates to the technical field of driving structure, and provides a linear reciprocatingly movement-type driving structure and a cleaning tool. The linear reciprocatingly movement-type driving structure comprises of: a driving gear and a crown gear engaged with said driving gear; an eccentric cam that is set eccentrically on the crown gear, a first connecting shaft is set on said eccentric cam, a crankshaft is sleeved on the said first connecting shaft, while the crankshaft is connected to an output shaft. In the utility model, the driving method of the motor 16 could be changed from a 360-degree rotation into a linear reciprocating motion through the driving gear, the crown gear, the eccentric cam, the first connecting shaft, the crankshaft and the output shaft. Therefore the wear and tear is reduced and the service life is prolonged.
