The limiting rod 21 is slidably connected to the inner wall of the limiting slide groove 22 opened in the inner side wall of the hollow cavity 17. The hollow cavity 17 is provided with a bidirectional screw 23. The bidirectional screw 23 passes through the two partition plates 24 and is rotatably connected to the through part by a bearing. The two ends of the bidirectional screw 23 are respectively threaded into the inner wall of the corresponding threaded groove 20. The bidirectional screw 23 is connected to the base 2 through a rotating mechanism. The front side of the base 2 is fixedly connected to a controller 3.

[0030] Preferably, a mounting bracket is fixedly connected to the lower end face of the base 2, and a storage battery 12 is fixedly connected inside the mounting bracket. Support columns are fixedly connected to the four corners of the lower end face of the base 2, and casters are fixedly connected to the lower end face of the support columns.

The servo motor 13 is electrically connected to the controller 3.

[0036] The specific working principle and usage method of this utility model are as follows:

[0037] This utility model provides a portable air booster device. In use, by starting the air pump 4, air is pumped into the pressure tank 7 via the air supply pipe 6. The amount of gas stored can be determined by observing the pointer of the pressure gauge 8. The device requiring pressurization is connected via the threaded connection of the connecting pipe 10. The gas is supplied to the pressure tank 7 by manually opening the valve on the surface of the connecting pipe 10. When it is necessary to disassemble the pressure tank 7 from the base 2, the servo motor 13 is controlled to rotate the worm gear 26. The rotation of the worm gear 26 drives the worm wheel 25 to rotate, which in turn rotates the bidirectional lead screw 23. The rotation of the bidirectional lead screw 23 causes the positioning plates 19 at both ends to move towards each other through the threaded grooves 20, thus separating the positioning plates 19 from the positioning slots 18. Then, the fixing frame 9 can be pulled up to separate it from the pressure tank 7, completing the disassembly of the pressure tank 7. During installation, the pressure tank 7 is placed... The pressure tank 7 is placed on the rubber buffer seat 11, and then the fixing bracket 9 is fastened to the surface of the pressure tank 7. The rubber buffer block 14 inside the fixing bracket 9 is fitted into the annular groove 15 on the surface of the pressure tank 7. The rubber buffer block 14 can protect the pressure tank 7 on the one hand, and prevent the pressure tank 7 from moving back and forth after installation, thus improving the stability of the pressure tank 7 after installation. The two ends of the fixing bracket 9 are respectively inserted into the corresponding sockets 16. After insertion, the servo motor 13 is controlled to drive the worm gear 26 to reverse, thereby causing the worm wheel 25 to drive the bidirectional lead screw 23 to reverse. This causes the positioning plates 19 at both ends of the bidirectional lead screw 23 to move in the opposite direction, so that the positioning plates 19 slide into the positioning through groove 18, thereby limiting the connection between the fixing bracket 9 and the base 2, thus completing the installation of the pressure tank 7. In summary, the installation of the pressure tube on the base 2 or its removal from the base 2 can be completed simply by controlling the forward and reverse rotation of the servo motor 13, which is convenient and improves the efficiency of disassembly and assembly.
