This creation is a kind of structural improvement at related portable type stamping machine side Pu,The side Pu include a gang of Pu ontology,One water outlet connector,One water supply connector and a reciprocating drive unit,Wherein the side Pu ontology include a water outlet,One water inlet and a piston chamber,Group connects water inlet and water outlet that helps Pu ontology respectively for aforementioned water supply connector and water outlet connector system,The wherein water inlet of what side Pu ontology and water outlet outer edge,It is respectively provided with the group buckle ear of at least one set,And what water outlet connector and water supply connector socket end outer edge,Also it is equipped at least one set of engaging portion for setting the embedding group of snapping of group buckle ear of what side Pu ontology water inlet and water outlet outer edge,Each engaging portion be formed with one for side Pu ontology water inlet and water outlet outer edge group buckle ear insertion caulking groove,And each caulking groove entrance lower edge of what and each group of buckle ear built-in end lower edge,It is respectively equipped with the inclined-plane of correspondence,And the fitting for keeping water outlet connector and water supply connector more smooth and closer when being socketed water outlet and the water inlet of what side Pu ontology respectively,When simultaneously in the water outlet and water inlet of what water outlet connector and water supply connector socket what side Pu ontology in produced gap,It is separately filled with leakproof colloid,And then so that the piston chamber for back and forth being pushed piston what side Pu ontology by reciprocating drive unit is generated reciprocal one and inhale a continuous action pushed away,Generation persistently absorbs water and the high pressure water flow of water spray is without generating leak,To reach the effect that is more powerful and stablizing and improve toothwash tha
