Novel sawing machine with vertical positioning mechanism

The utility model discloses a novel sawing machine with a vertical positioning mechanism, which relates to the technical field of sawing machine equipment and comprises a base, supporting plates are fixedly connected to the top ends of two sides of the base, and a cutting unit and a protection mechanism are mounted at one end of each supporting plate. By arranging the protection mechanism, illegal operation on a cut piece can be avoided, the motor is started to drive the second gear to rotate through the first gear, meanwhile, the second gear drives the third gear to rotate through the linkage belt, and at the moment, the third gear drives the threaded rod to rotate; meanwhile, a threaded rod drives a lifting pressing plate to descend to limit and extrude the cut part, at the moment, one first gear is meshed to drive the other first gear to rotate, the other first gear drives a fourth gear to rotate, and at the moment, the fourth gear is meshed to push a protection push plate through a rack to drive a limitin
