Synchronized multidirectional movement mechanism for cleaning tool and cleaning tool provided with the mechanism

Abstract

Disclosed are synchronized multidirectional movement mechanism for cleaning tool and a cleaning tool. The mechanism includes at least one set of movement units and a drive module for driving all the movement units. All the movement units are capable of driving cleaning heads disposed thereon to, driven by the drive module, perform reciprocating movement in different directions between a first position corresponding to an operating state and a second position to a non-operating state of the cleaning heads. Thus, burden caused by carrying more than two types of cleaning tools simultaneously can be avoided by separately providing cleaning heads with different cleaning functions on at least one set of movement units. Meanwhile, the cleaning head in the non-operating state can be driven by the corresponding movement unit to a position relatively compact with a mounting base. Moreover, convenient operation can be achieved by a single drive module.
