The automatic battery charging and replacing device as claimed in claim 8 or 9, wherein: the second linkage power tooth is sleeved on the second linkage intermediate shaft in an axially slidable and non-circumferential rotation manner, two end faces of the second linkage power tooth are respectively assembled with a shaft ring of the first thrust ball bearing and a shaft ring of the second thrust ball bearing, a seat ring of the first thrust ball bearing and a seat ring of the second thrust ball bearing are respectively assembled with one end of a first switching spring and one end of a second switching spring, the other end of the first switching spring and the other end of the second switching spring are respectively assembled with a third lifting transverse plate and a seat ring of a third thrust ball bearing, the shaft ring of the third thrust ball bearing is installed on a switching push plate, a switching chute is arranged on the switching push plate, the switching chute is clamped with a switching slide rail and can be assembled in a sliding manner, and the switching slide rail is installed on the lifting frame; in the initial state, the switching slide rail is tightly attached to the second lifting transverse plate;

the bottom of the second linkage intermediate shaft penetrates through the second lifting transverse plate and then is assembled with the first clutch disc; when the lifting frame moves downwards to the maximum displacement point, the first clutch disc and the second clutch disc are pressed for transmission, the clutch push rod penetrates through the lifting top groove and then pushes the switching push plate upwards, and therefore the second linkage power tooth is pushed upwards, and the second linkage power tooth is separated from the first linkage and is not meshed any more;

the clutch push rod is arranged on the clutch seat, the second clutch disc is arranged at the top of the clutch sliding sleeve, a clutch sliding hole with an opening at the bottom is arranged on the clutch sliding sleeve, a clutch shaft is arranged in the clutch sliding hole in a non-circumferential rotating and axial sliding manner, the bottom of the clutch shaft passes through the second clutch partition plate and then is assembled with the clutch worm wheel, the clutch sliding sleeve and the first clutch partition plate can be assembled in a circumferential rotating and axial moving manner, a clutch spring is arranged between the top surface of the clutch sliding hole and the top surface of the clutch shaft, and the clutch spring is used for applying elastic force for preventing the clutch sliding sleeve from moving downwards;

the clutch worm wheel is partially meshed with the clutch worm to form a worm wheel and worm transmission mechanism, the clutch worm is partially arranged on a clutch power shaft, the clutch power shaft and a clutch seat can be assembled in a circumferential rotating mode, and one end of the clutch power shaft penetrates out of the clutch seat and then is connected with a first material pushing motor shaft through a clutch belt to form a belt transmission mechanism; the first clutch partition plate and the second clutch partition plate are both arranged on a clutch seat, and the clutch seat is arranged on the second linkage frame plate.
