The present invention relates to a driving apparatus of a length shortening syringe, and more specifically, to a driving apparatus of a syringe which is mounted onto an injection apparatus (10), pushes a piston (12) installed in an injection cartridge (11) in which an outlet (13) is formed on an end of one side, and operates to discharge a predetermined amount of a content. The driving apparatus of the length shortening syringe comprises: a rotation driving unit (110) which is installed on one or more outer sides of an end on the other side of the injection cartridge (11); and a unidirectional bending member (120) which has an end of one side installed adjacent to the piston (12), is capable of bending toward one direction only, and has a side of the bending direction driven by the rotation driving unit (110) in order to push and drive the piston (12). According to the present invention, if major elements are located on an outer side of the injection solution cartridge and a same stroke (I) exists, a length of the entire driving apparatus is significantly reduced, thereby being portable and realizing various shapes of injection apparatuses. |
