The invention provides a telescopic and folding gas bottle cart which comprises a main push frame, telescopic pull rods, supporting arms, folding mechanisms and a bearing bottom plate connected to the bottom of the main push frame. The main push frame is formed by fixedly connecting supporting frames and push rods. The push rods are provided with hollow cavities. The telescopic pull rods are movably connected with the push rods in a sleeving manner. The push rods and the supporting arms form movable hinge structures through connecting pieces. Two connection pieces are hinged into a whole to form one folding mechanism. One end of each folding mechanism is movably hinged to the corresponding push rod. The other end of each folding mechanism is movably hinged to the corresponding supporting arm. Locking mechanisms are arranged between the telescopic pull rods and the push rods. When the telescopic pull rods stretch out by a certain distance relative to the pull rods, the telescopic pull rods and the pull rods are kept in the locked state through the locking mechanisms. By means of the telescopic and folding gas bottle cart, the space occupied by the telescopic and folding gas bottle cart can be reduced to the maximum degree, the telescopic and folding gas bottle cart can be stored nearby very conveniently, and replacement of a gas bottle is facilitated.
