However, the existing gas cylinder device is provided with rollers at the bottom and supporting legs in the middle. The device is tilted by rotating the rollers, so that the supporting legs are lifted off the ground. When the gas cylinder is placed, the supporting legs are in contact with the ground. In this way, the gas cylinder is always in an inclined state, and the rollers are always in contact with the ground. The device is not stably fixed, and the relative supporting legs are also in contact with the ground. The device occupies a large area. SUMMARY

The supporting block is used to support the gas cylinder, and the arc-shaped concave surface is matched with the arc-shaped surface of the lower part of the gas cylinder to improve the stability of the support.

[0005] The lower end of the base is provided with a fixed table, the fixed table comprises a fixed plate, a fixed hole is formed through the fixed plate, a guide rod is vertically fixedly connected to the center of the inside of the base, a lock block with a cylindrical stepped structure is slidably arranged on the guide rod, the lower part of the lock block is matched with the fixed hole, a spring is arranged on the upper part of the lock block and abuts against the inner wall of the base, and a pulling rod is fixedly connected to the sidewall of the upper part of the lock block. The fixed table is fixed in advance, that is, it is fixed in the area where the gas cylinder is taken. The device pushes the gas cylinder to the fixed table, then rotates the base so that the gas cylinder is in a vertical state, that is, the lower end surface of the base is horizontal. At this time, the base moves above the fixed table, and the lock block moves downward and is matched with the fixed hole, so that the posture of the device is maintained, which is beneficial to reducing the occupation of space and the stability of the gas cylinder.

[0006] Preferably, the edge of the base is fixedly connected with two columns, the two columns are fixedly connected with a back plate, and the two columns are rotatably connected with a rotating cover plate, the back plate and the rotating cover plate form a circular profile in plan view, and the gas cylinder is located inside the circular profile.

[0007] Preferably, the upper part of the column is bent, and the end is sleeved with a push handle. The push handle is used for pushing the device, and the gas cylinder is convenient to transfer.

[0008] Preferably, the side of the base is provided with an inverted L-shaped opening, and the push rod extends out of the L-shaped opening. The position of the lock block can be changed up and down through the push rod, and the structure of the L-shaped opening can turn the push rod into the shorter part of the L-shaped opening, so that the compression spring keeps the lock block in the state of being located inside the base.

[0009] Preferably, the side wall of the base is fixedly connected with a V-shaped support, and the end of the support is rotatably matched with a roller. The support is provided with two, and each column is provided with a support on the same side. When the device is normally pushed, it rotates around the roller, and at this time, the push handle is in a horizontal state.

[0010] Preferably, the side of the base is fixedly connected with a V-shaped support, and the end of the support is rotatably matched with a roller. The support is provided with two, and each column is provided with a support on the same side. When the device is normally pushed, it rotates around the roller, and at this time, the push handle is in a horizontal state.

[0011] The beneficial effects of the present application are as follows: the fixed table is provided, and the lock block is arranged in the base. When the device is placed, the lower part of the lock block extends into the fixing hole on the fixed table, so that the device and the gas cylinder are in a vertical state and are kept, which greatly improves the stability of the gas cylinder placement, and reduces the occupied area when placed vertically.
