Abstract
A device for rapidly loading and releasing a syringe. A limiting flange and clamping flange are on an outer side wall of an end, connected to the device, of the syringe. The clamping flange is close to a rear end of the syringe. The device includes an injection head. An outer collar, middle plate, and inner collar are sequentially inside the injection head. The outer collar includes an upper and lower part that are disposed up and down. The inner collar includes an upper part of the inner collar and a lower part of the inner collar that are disposed up and down. Elastic structures are between the upper part of the inner collar and injection head and between the lower part of the inner collar and injection head. The injector syringe can be loaded onto the device and taken out rapidly if the syringe is rotated.
