1. A vacuum packaging device comprising:
a hexahedral housing having a space inside;
a grip unit in which a pair of grip bars selectively come into surface contact with each other above a front side of the housing and which grip ends of a packaging bag that has entered between the pair of grip bars;
a suction nozzle unit which moves forward and backward along a guide inside an inner space of the housing, enters an opening of the packaging bag gripped by the grip unit, and sucks the atmosphere inside the packaging bag to be a vacuum state;
a pair of heat-pressing members which are respectively provided in the pair of grip bars, come into surface contact with each other to heat-press the ends of the packaging bag for which the suction has been completed to heat-fuse and seal the packaging bag;
lifting and lowering means for lifting and lowering an upper grip bar of the pair of grip bars and an upper heat-pressing member of the pair of the heat-pressing members inside the inner space of the housing by a process step;
fixing spaces, which are open in directions facing each other in a longitudinal direction, respectively formed inside the pair of grip bars; and
elastic bars, each elastic bar having
a fixing body which has a length corresponding to a corresponding fixing space of a corresponding grip bar and is accommodated by being coupled to the corresponding fixing space of the corresponding grip bar and
a grip head having a semicircular cross-sectional shape in a vertical direction along the longitudinal direction, the grip head protruding from an upper end of the corresponding grip bar,
wherein a portion of the grip head forming a boundary with each fixing body is formed to extend in a front-rear direction with a length corresponding to a width of each grip bar to form a step supported on an upper end of each grip bar,
wherein a width of the semicircular cross-section shape of the grip head is same as a width of each grip bar, the width extending from one end of a vertical outer surface to the other end of the vertical outer surface of each grip bar.
