Driving module and handheld high-pressure cleaning machine

The utility model relates to a drive module and handheld high pressure washer, including motor subassembly, transmission subassembly connected with the motor subassembly and the plunger that is driven by the transmission subassembly, the transmission subassembly includes box shell, connect with the speed reduction mechanism of motor subassembly and connect with the output piece of speed reduction mechanism, the output piece drives the plunger to do reciprocating motion; the output piece comprises a frame body connected to the speed reducing mechanism and an eccentric part connected to the plunger, the eccentric part is fixedly connected to the frame body, and the frame body and the eccentric part are of a split structure. On the premise that the transmission requirement is met, the eccentric part is made of materials which are good in material quality and high in cost, the frame body can be made of materials which are poor in material quality and low in cost, and therefore the manufacturing cost of the whole
