The technical scheme has the technical effects that the lifting assembly is arranged, the bottom rollers can be lifted and lowered by only stepping on the footboard and removing or pushing in the support block, and the two modes of the gas pressure boosting cabinet can be switched: when the cabinet body needs to be moved, the rollers are lowered, the entire cabinet body can be easily moved, time and labor are saved; when the cabinet body needs to be placed stably, the rollers are raised, the baffle touches the ground, the stability of the entire cabinet body is increased, and the problem of reduced gas compression quality caused by the displacement of the cabinet body due to external force is avoided.
