Bidirectional adjusting mechanism and bidirectional-adjustable screen printing machine printing plate device

The invention discloses a bidirectional adjusting mechanism and a bidirectional-adjustable screen printing machine printing plate device. The bidirectional adjusting mechanism comprises an adjusting assembly and a connecting assembly. The adjusting assembly comprises a limiting piece and an adjusting piece which are used for limiting the connecting assembly. The connecting assembly comprises a fixing piece and a connecting piece which are connected with a printing plate. The connecting piece and the limiting piece are in limiting inserted connection or detachable fixed connection. The adjusting piece drives the connecting assembly to move forwards and backwards through the limiting piece so as to adjust the deformation of the printing plate and the gauze tension of the printing plate. Thescreen printing machine printing plate device comprises a plate frame and the printing plate which are fixed to a reciprocating frame. The bidirectional adjusting mechanism is arranged between the plate frame and the printing
