Novel bidirectional machine vice

The utility model relates to a novel bidirectional machine vice which comprises a vice body. The vice body comprises a vice body and a fixed jaw; the clamp body is provided with two clamping stations located on the two sides of the fixed jaw respectively. The novel bidirectional machine vice further comprises a plurality of sets of auxiliary positioning arms. The auxiliary positioning arm comprises a transverse connecting arm, two sets of suction cups in one-to-one correspondence with the two clamping stations, and a positioning plug pin fixed to the middle of the connecting arm. The two groups of suckers are fixedly arranged at two ends of the connecting arm respectively; a plurality of positioning grooves matched with the positioning bolts are formed in the upper surface of the fixed jaw; the multiple positioning grooves are linearly arranged, and the arrangement direction of the multiple positioning grooves is the same as the length direction of the fixed jaw.
