Tool locking valve mechanism of full-hydraulic paper cutter

The utility model discloses a tool locking valve mechanism of a full-hydraulic paper cutter. The tool locking valve mechanism comprises a tool locking valve body (14); a vertical inlet (18) and a transverse outlet (19) which are communicated are arranged in the tool locking valve body; a left valve core (8) and a right valve core (10) which are mutually connected are mounted on the intersection of the vertical inlet and the transverse outlet of the tool locking valve body; the left valve core is connected with an adjusting rod (2); and a stopping sheet (11) is mounted at the outer end of the right valve core through a spring (13). According to the tool locking valve mechanism provided by the utility model, the left valve core is pushed through the rotation of the adjusting rod, so that an opening state and a closing state can be formed between the right valve core and the tool locking valve body; and pressure oil of the hydraulic system is controlled to be output or not, so that a cutting tool device stops a
