Described standby tool magazine is provided with and can stores manyly the plug-in of blade storage cutter groove, is provided with the activity capping at the afterbody of storage cutter groove.

Described blade extension elongation governor motion comprises push button, spring, thimble and knob, described upper tool post side is provided with the chute that is used to install push button, described lower slide inboard is provided with a plurality of detents, push button is installed in the chute of upper tool post and to pass the side chute of handle of a knife protruding, push button can slide before and after the chute of upper tool post side, push button is provided with, the screw of following perforation, the bottom of screw is provided with a undergauge step, spring is arranged in the screw and is pressed on the step, thimble passes and can pass that blade forms the location in the detent that blade stretches into the lower slide inboard in the middle of the spring, in knob is connected on the screw of push button and spring and thimble be sealed on.

The described blade that is stored in the standby tool magazine is the 4-5 sheet.

The utility model multifunctional cutting cutter can reach the purpose that goes out cutter fast by promoting knife rest, adjust the extension elongation of blade by blade extension elongation governor motion, adjust the increasing degree of knife rest blade intensity by different extension elongations, satisfied difference cuts the intensity of object and the demand of length.Has advantage rational in infrastructure, easy to use, that tool changing quick, the blade utilization rate is high.
