Preferably, the base is a rectangular plate made of metal or alloy material, so that the contact area between the base and the ground is larger, the weight is heavier, the center of gravity of the whole fixing device is moved downwards, and the stability of the whole fixing device is improved. The bracket 12 can be an arc plate, an angle steel plate, a plane plate or a bent plate with an obtuse angle; preferably, the bracket 12 is not a flat plate, so that the contact area of the clamping air bag and the gas cylinder after inflation is larger, and the stability of the gas cylinder is better; more preferably, support 12 is the arc, makes the appearance that sets up the tight gasbag of clamp on support 12 lateral wall more laminated the gas cylinder, makes the area of contact maximize of the tight gasbag of clamp and gas cylinder, and stability is better.

The two ends of the clamping track 211 can be connected to the connecting pieces 212 on both sides of the frame 12 by screws or pins or fasteners, respectively.
The connecting piece 212 is a sheet-shaped connecting lug 241 or a connecting plate; the connecting lug 241 or the connecting plate is provided with a through hole for connecting the clamping track 211. Alternatively, the connecting tab 241 or the through hole on the connecting plate may be provided singly or in multiple
Alternatively, the clamping track 211 may be made of an elastic rubber material.
In some embodiments, the clamping member 21 further includes a fixing wire 25, and the fixing wire 25 is made of a metal material; the fixing wire 25 is wound around the outside of the clamping track 211 and then both ends are connected to both sides of the bracket 12 of the link 212, respectively; the length of the fixed line 25 is larger than the length of the clamping crawler 211 under the non-stressed condition and smaller than the maximum length of the clamping crawler 211 under the stressed condition, so that the position of the gas cylinder is limited, the gas cylinder is not inclined due to the elasticity of the clamping crawler 211, the clamping strength of the clamping crawler 211 to the gas cylinder can be enhanced, the tensioning degree of the clamping crawler 211 is limited, and the service life of the clamping crawler 211 is prevented from being influenced by the excessive tensioning of the clamping crawler 211.

Optionally, the fixing line 25 is fixedly connected to the connecting plate through a screw, a pin or a buckle; alternatively, the fixing wire 25 is connected to the connection plate by welding or bonding.
In some embodiments, the fixing wire 25 is slidably mounted at both ends on the two connecting plates. The structure is specifically realized by the following structure: the connecting plates are provided with sliding grooves or waist-shaped holes; sliding blocks are respectively arranged at two ends of the fixed line 25; the sliding block can be an I-shaped sliding block or a T-shaped sliding block; the two sliding blocks are respectively embedded into the two sliding grooves or the waist-shaped grooves and can slide along the sliding grooves or the waist-shaped grooves. The fixing line 25 and the connecting plate are slidably mounted, so that the fixing line 25 has a certain movement allowance, and the size of the gas cylinder suitable for the fixing device is wider.
In some embodiments, the connecting member 212 is connected to the clamping member 21 by a tension spring, and the clamping member 21 always clamps the gas cylinder by the restoring force of the tension spring, so as to maintain the fixed state of the gas cylinder.

The multipoint fixation of the gas cylinder can be realized through the two wings of the right-angled or obtuse-angled angle steel, so that the fixation effect is better.
In some embodiments, the inner side walls of the two wings of the angle steel are provided with the flexible gaskets 121, so that the contact between the gas cylinder and the inner side walls of the angle steel is softer, and the surface of the gas cylinder is prevented from being crushed or scratched; meanwhile, the friction force between the gas cylinder and the angle steel can be improved, and the gas cylinder is prevented from sliding with the inner side wall of the angle steel in the fixing process.
In some embodiments, the base further comprises a support plate 13 mounted on the support 12 and perpendicular to the support 12; the supporting plate 13 is parallel to the bottom plate 11 and disposed close to the bottom plate 11. The support plate 13 is used for supporting the bottom of the gas cylinder.
