An adapter structure for a gas fuel bottle cooperates with a bottle and is connected with a power tool. The adapter structure contains a body connecting with the bottle, a gas sealing assembly fixed inside the body, a fixing member cooperating with a spherical connecting portion of the power tool, and a plurality of elastic retaining members secured on the fixing member. Each elastic retaining member forms an elastic spreading mouth, and a diameter of the elastic spreading mouth is normally smaller than that of the spherical connecting portion, the elastic spreading mouth is pressed to expand so that the spherical connecting portion slides into or disengages from the opening. Each of the elastic retaining members is separated from the fixing member, whereby the adapter structure benefits easy die sinking and assembly.
