Reset component of injector

The invention relates to the technical field of an injector, in particular to a reset component of the injector. The reset component comprises a reset core rod, a reset cylinder, a reset piston and abase, the reset cylinder is provided with an inner cavity used for accommodating a fluid medium, the reset piston is fixed on the base, and a space between the reset core rod and the reset piston is filled with the fluid medium. When the piston of the injector needs to be reset, the reset core rod is pushed downwards firstly to enable the fluid medium in the inner cavity to push the reset cylinderto move upwards, then the reset core rod is inserted into the injector and enabled to contact with the piston, the injector is relatively fixed to the reset component, and finally by means of pressing down the reset cylinder, the piston can be jacked up by the reset core rod and is reset. The reset component of the injector has the advantages that the piston can be pushed back and kept a certaindistance from a push rod af
