Drying machine for interior of gas cylinder

The utility model relates to the technical field of gas cylinders, in particular to a gas cylinder interior drying machine which comprises a drying machine base, two ends of the upper surface of the drying machine base are fixedly connected with supporting frames respectively, a movable base is arranged between the two supporting frames, and two ends of the movable base are slidably connected to the inner sides of the two supporting frames through fixing blocks respectively. Compared with the prior art, through the arrangement of the supporting frame, the movable base and the clamping plate, in the using process of the device, firstly, the movable base is driven by the two fixing blocks to adjust the fixing position according to requirements, and then a gas cylinder is placed in a fixing hole formed between the movable base and the clamping plate; and the problem that the fixing position of a traditional device cannot be adjusted according to the specification of the gas cylinder is solved. 本实用新型涉及气瓶技术领域的一种气瓶
