Abstract: A syringe positioning assembly includes a housing, a rotating member, a fixing member and a transmission member. The rotating member is connected to the fixing member via the transmission member, and during rotation, the rotating member can, via the transmission member, drive the fixing member to move. When the rotating member rotates in a direction away from a carrying face of the housing, the fixing member can be moved in a direction away from the fixing face. A space between the rotating member and the carrying face of the housing facilitates placement of a barrel of a syringe and a space between the fixing member and the fixing face of the housing can also facilitate placement of a barrel flange. A user can thus move the fixing member just by operating the rotating member, so that the syringe can be easily mounted and properly positioned.
