1. A standing device, wherein the standing device comprises a support frame, a plurality of transverse support plates, a plurality of clamping jaw assemblies, and a sealing box;
wherein the plurality of the transverse support plates are fixedly connected to the support frame and enclosed to form a holding position for accommodating the upper cover and the lower cover, and each of the transverse support plates is provided with at least one of the clamping jaw assemblies for clamping the upper cover and the lower cover; and
wherein the sealing box comprises:
an upper cover;
a lower cover, detachably connected to the upper cover, and enclosing with the upper cover to form an accommodating chamber for accommodating a workpiece; one side of the lower cover toward the upper cover defining a sealing groove surrounding the accommodating chamber; and
an elastic sealing ring, sealedly disposed in the sealing groove, and comprising a sealing end sealedly contacting the upper cover and a deformation end accommodated into the sealing groove;
wherein the lower cover defines an inflation hole communicated with the sealing groove, the deformation end is deformed under force of airflow inflated into the sealing groove by the inflation hole, thereby squeezing groove walls of the sealing groove and generating a force to push the sealing end to move toward the upper cover.
