It is further preferred that a plurality of fins 3323 are uniformly disposed on the outer wall of the plunger rod 332, and the cross-sectional shape of the stopper 3313 is opposite to the cross-sectional shape of the space between two adjacent fins 3323, so that the plunger rod 332 can move only in the axial direction with respect to the barrel 331 during the aspiration/discharge and/or the discharge of the auto-injector 330. In this embodiment, three fin plates 3323 are provided, but two, four, five, etc. may be provided.

As shown in fig. 10, in the three states, wherein the position of the piston rod 332 in the barrel 331 is different, the state of the spring 333 is also different; first, in an unused state, in which the spring 333 is in a naturally extended state, the plunger rod first end 3321 is positioned closest to the syringe port 3311, and the syringe is in an evacuated state; then when in use, the syringe is fully pumped with gas or liquid, the syringe is in a state of fully pumping gas/liquid, the spring 333 is in a stretching state, and the switch component can be closed (the piston rod 332 is rotated to enable one side of the clamping plate close to the first end 3321 of the piston rod to be abutted against the stop 3313, and the resistance of the stop 3313 on the clamping plate is balanced with the stretching retraction elasticity of the spring 333); when it is then necessary to inflate/inflate the capsule 310, the piston rod 332 is rotated to disengage the catch plate from the stop 3313, the piston rod 332 moves towards the injection port 3311 under the action of the retracting elastic force of the spring 333 to compress the gas or liquid in the barrel 331, so as to press the gas or liquid into the capsule 310, and the self-inflating/self-inflating state is completed when the retracting elastic force of the spring 333 is balanced with the pressure of the gas or liquid in the capsule 310. Preferably, a mark can be arranged on the piston rod 332 to indicate that the balloon 310 is in a normal swelling state, and when the position of the piston rod 332 changes, the state of the balloon at the tip of the bronchoscope changes, so that a user can judge and monitor whether the balloon in the body is in a normal blocking state according to the specific position of the piston rod 332 outside the body, and the judgment method is simple, convenient and quick, and avoids the injury of the balloon to the wound of a patient and the mucous membrane in the body caused by repeatedly taking out and putting in the balloon.
