1. A pneumatic-fixation connecting device comprising:
a connecting pin, comprising a protruding unit at one end of the connecting pin;
a body, comprising an extension tube and a plurality of placement holes, wherein the plurality of placement holes are located at a periphery of the extension tube, wherein the extension tube comprises a connecting hole and a plurality of through holes, the connecting hole is used to accommodate the connecting pin, and the plurality of through holes are located on the extension tube;
a movable part movably disposed in a stacking manner to the body for moving relative thereto, the movable part comprising a base and a protrusion ring, wherein the protrusion ring is located on a surface of the base, an inner surface of the protrusion ring forms a coupling hole for accommodating the extension tube, and the inner surface of the protrusion ring has at least one protruding portion thereon;
a plurality of elastic units, disposed respectively in the plurality of placement holes of the body, and one end of each elastic unit being in contact with the base of the movable part;
a plurality of stop units, disposed respectively in the plurality of placement holes of the base, wherein each stop unit is in contact with another end of the elastic unit; and
a plurality of spheres, disposed between the protrusion ring and the extension tube, wherein when the distance between the movable part and the body increases, the protruding portion of the protrusion ring pushes the spheres to force a partial volume of the sphere enter the connecting hole via the through hole of the extension tube and affix the protruding unit of the connecting pin, and when the distance between the movable part and the body decreases, the sphere does not affix the protruding unit of the connecting pin.
