Claim 6:
7. A needleless injector comprising:
a cylinder housing having a stopper wall formed at a rear end portion and a slit extending rearward from a front end portion;
a loading lever having a working arm part having a lever shaft, which is rotatably coupled to the cylinder housing behind the stopper wall, formed at one end portion and a handle part extending from the other end portion of the working arm part by being bent at a predetermined angle so that the handle part is rotatable to a folded position where the handle part lies on the cylinder housing;
a spring inserted inside the cylinder housing;
an actuating head inserted inside an inner cylinder so as to be able to slide back and forth in front of the spring and having a catching protrusion, which is configured to protrude radially toward an inner circumferential surface of the cylinder housing, and a loading protrusion, which is configured to pass through the slit;
a loading cylinder configured to be coupled to an outer side of the cylinder housing so as to be able to slide back and forth, configured to be coupled to the loading protrusion of the actuating head through an inner circumferential surface, and having an open section extending in a front-rear, longitudinal direction;
a link having one end portion pin-coupled to the handle part at a position adjacent to the lever shaft and the other end portion pin-coupled to a rear end portion of the loading cylinder so that the loading cylinder is able to slide back and forth at the outer side of the cylinder housing according to a rotation of the loading lever; and
a trigger means coupled to the outer side of the cylinder housing through the open section of the loading cylinder and having a stopper head part configured to pass through the cylinder housing so as to be able to protrude and be detached from the inside of the cylinder housing,
wherein the cylinder housing includes a hinge plug coupled to a rear end portion of the cylinder housing and having a shaft accommodating part, to which the lever shaft is coupled, and the stopper wall.
