Movable air compressor

According to the movable air compressor disclosed by the invention, an inclined part is arranged on a second bracket of a shelving assembly, and a sliding seat, an auxiliary wheel, a limiting block and an elastic assembly are arranged on the inclined part, so that the auxiliary wheel is lower than a rubber buffer cushion block after sliding under the action of gravity, and an air compressor body is convenient to move; and by combining a downward pressing assembly on the second support, an elastic rotating mechanism at the joint of the pushing handle and the tank body and a linkage mechanism, when the pushing handle is pressed downwards, a limiting block can be separated from a limiting square hole, and a rubber buffer cushion block is supported on the ground again. Finally, in the process of lifting the rear end of the air compressor body by lifting the pushing handle upwards, the auxiliary wheels are supported on the ground, and the rubber buffer cushion blocks are separated from the ground, so that the air
