Abstract

The invention provides an accurate, durable mini syringe pump. The said syringe pump (11) comprises a motor (1) and rotary shaft (1a), a reduction gear (2) disposed on the bottom and linked with a connection member (15) to form an internal rotary drum (3) and screw element (37), and an external screw element (41) and movable piece (4) which is coupled with the internal screw element (37); the connection member will cause the movable piece (4) rotating axially in the drum (3) along the guide means; the movable piece has a piston rod (9) moving within the cylinder (81); the guide means will guide movable piece passing through a guide pin (5) disposed in axial direction of the drum (3); tow supporting bodies (6,7) are disposed in parallel and mounted on two ends of the guide pin (5), the supporting body (6) supports the top of drum (3) and the supporting body (7) supports the bottom of drum (3) to keep the drum (3) in the rotary state and to inhibit the swing of the drum (3).
