The invention provides a rotation and rectilinear motion device arranged on a rack. The device comprises a drive part, a driving part, a carrying moving part and a restricted rotating part, wherein the drive part is used for driving the driving part; the driving part is used for driving the carrying moving part, and is a vertical rod which has a top end, a middle section and a lower end and rotates around the axis of the driving part; an adsorption element is arranged at the top end of the driving part, an outer thread is arranged on the outer surface of the middle part of the driving part, and the lower end of the driving part is connected with the drive part; the carrying moving part is used for carrying objects to move, and is provided with a first through hole and at least one second through hole; the first through hole is formed at the geometric center of the carrying moving part, an inner thread meshed with the outer thread is arranged in the first through hole, and the second through hole is arranged near the first through hole; at least one restricted rotating part is used for restricting rotation of the carrying moving part, is fixedly arranged on a rack, and penetrates through the second through hole; the upper end of the restricted rotating part is lower than the upper end of the outer thread; and the adsorption element is used for adsorbing the carrying moving part when the carrying moving part is moved to the upper end of the outer thread, so that the carrying moving part is separated from the outer thread.
