Removing the support material with traditional hand tool mode can consume a large amount of manpower and time, and is inefficient, is difficult to satisfy the production demand.

Therefore, the Chinese patent: the supporting material removing device with application number CN201821460431.6 discloses that high-pressure water is sprayed to a model to be cleaned through a cleaning unit, so that the supporting material in the model to be cleaned is removed, and meanwhile, the device is switched by arranging nozzles with two shapes, namely a tubular nozzle and a knife-shaped nozzle, under the operation of a change-over switch, so as to spray high-pressure water flows with different shapes, and can be used for removing the supporting materials with different shapes.

However, in order to spray high-pressure water flows with different shapes, the two nozzles with different shapes are arranged on the device, and the nozzles with different shapes are switched through the switch to operate, so that the step is complex, the two independent nozzles also easily occupy more space in a cleaning cavity, and the effect of spraying high-pressure water flows with different shapes by the independent nozzles is difficult to realize.
