A liquid dispensing device includes at least one piston pump ( 7 ), which sucks liquid to be dispensed from a container in a filling cycle and applies the liquid to a target in an emptying cycle and which is driven by an actuator comprising an actuating element ( 1 ) that is arranged to move a piston rod ( 2 ) between two extreme positions, and a gripper ( 3 ) attached to the actuating means ( 1 ), which gripper is able to engage with the piston rod ( 2 ) so as to move it along with the actuating element. The gripper ( 3 ) is made able to engage with the piston rod ( 2 ) only in its first extreme position and arranged to disengage automatically from the piston rod in its second extreme position.
