[0016] 2. A limiting structure is set between the sleeve and the fixed plate. The limiting block of the limiting structure is inserted into the limiting groove to limit the sleeve, so as to prevent the sleeve from driving the bidirectional screw rod to rotate, improve the stability of the rotating seat angle maintenance, and thus improve the stability of the air tank installation.

[0017] 3. The mounting frame is provided with a top block, a side plate and a pressure block. A pressure block is provided under the gas cylinder, and the pressure block is located between the two side plates, and between the side plate and the top block.

During the relative sliding process, the two transmission blocks 212 push the lifting block 213 to move through the inclined surface, the first spring 216 is compressed, and the lifting block 213 drives the pressing block 26 to press on the gas cylinder 3 synchronously, so as to fix the gas cylinder 3 on the mounting frame 2. Rotate the bidirectional screw 28 in the opposite direction, so as to separate the side plates 25, the pressing block 26 and the gas cylinder 3, so as to facilitate the disassembly of the gas cylinder 3.

[0041] S3, rotate the mounting base 21, adjust the angle of the mounting base 21 to the mounting angle, rotate the crank 234, the crank 234 drives the transmission sleeve 231 to rotate, the transmission sleeve 231 slides inward through the transmission groove 233 and the transmission pin 232, the transmission sleeve 231 drives the locking rod 225 to slide inward through the connector 229, the end of the locking rod 225 is locked on the mounting base 19 through the anti-slip platform 110 and the anti-slip groove, and the crank 234 is fixed on the limit plate 230 through the top screw.

[0042] S4. The transmission screw 15 is driven to rotate through the handle 117, and the transmission screw 15 drives the slide 16 to slide along the transmission screw 15. The slide 16 drives the limit column to slide in the limit hole 17. The limit column drives the rotating seat 12 to rotate through the diagonal support rod 13 to adjust the angle of the rotating seat 12. The fixed seat 11 is fixed on the chassis to complete the installation of the gas cylinder 3. In order to further improve the stability of the gas cylinder 3, after the gas cylinder 3 is installed on the automobile chassis, a rigid rod can be used to connect the mounting seat 21 and the chassis to further improve the stability of the mounting frame 2.
