A syringe pump includes a lead screw, a cam, and an assembly having first and second arms each having a first end and a second end. The second ends of the first and second arms are configured to engage with the lead screw. The first ends of the first and second arms are configured to engage with the cam such that actuation of the cam toward the assembly causes the second ends of the first and second arms to pivotally approach each other. The second ends of the first and second arms each includes threads to engage the lead screw when the second ends of the first and second arms approach each other. The plunger head coupled to the assembly and operative to drive a plunger of a syringe into a barrel of the syringe.
