A stackable gas cylinder includes a body, a base connected to a bottom portion of the body, and a protective ring connected to a top portion of the body. A size of the base is greater than a size of the protective ring. The protective ring of the other gas cylinder is insertable into the base of the gas cylinder in a stacked manner. Accordingly, stacking can be achieved stably, so as to reduce storage space. |
