Memory alloy wire confrontation type driving double-acting continuous output micro pump

The invention discloses a double-acting continuous output micro pump driven in an adversarial mode through a memory alloy wire, and belongs to the field of hydraulic pumps. The micro pump is composed of a one-way valve set, a guide pipe set, a pump body, an end cover, a screw, a gasket, an electrode, an electrode plug, an electrode plug sealing ring, a plastic pipe with a spiral wire, a memory alloy wire set, a piston and a piston sealing ring. The micro pump controls power on and power off of the upper end and the lower end through the single-pole double-brake switch, when the upper end is powered on, the memory alloy wire at the upper end is shortened to drive the piston to move upwards, fluid is discharged from the upper end, and fluid is input into the lower end; when the lower end is electrified, the memory alloy wire at the lower end is shortened to drive the piston to move downwards, the lower end discharges fluid, and the upper end inputs fluid. The device is simple in structure, small in size, free o
