The invention relates to an atmospheric pressure low-temperature plasma jet treatment device with adjustable mesh number of screen electrodes. The atmospheric pressure low-temperature plasma jet treatment device comprises an assembly body, a fixed table, a first support body, an air inlet, a plasma generator, a second support body and a high-voltage frequency adjustable alternating current power supply, wherein the plasma generator comprises a screen electrode, a glass dielectric plate and a circular electrode. According to the invention, the problems of non-adjustable plasma jet position and insufficient material processing caused by the fixed structure of the plasma jet device are solved, the distance of the plasma jet processing material can be adjusted at any time, and the mesh number of the screen electrode can be changed at any time; in addition, the position of a processed area can be adjusted at any time, the area of plasma jet can be increased at any time, all-directional material processing is truly
