Abstract

The present invention provides a double-piston mechanism of an emulsion squeeze head, having an actuating syringe and a suction pipe. A top of the suction pipe is connected to a pressing head, while an elastic resetter is arranged between the bottom of the suction pipe and the bottom wall of the actuating groove. The suction pipe is also provided with a piston set. The piston set includes a first piston, with a first connecting portion and a first flange, and a second piston. The first connecting portion is assembled onto the suction pipe, and the first flange is abutted on the wall of the actuating groove. The second piston, placed at one end of the first piston, includes a second connecting portion and a second flange. The second connecting portion is assembled onto the first piston, and the second flange is abutted on the wall of the actuating groove.
