The invention discloses a movement component for placement. The movement component comprises a transverse drive assembly, a vertical drive assembly, and a support for supporting the transverse drive assembly. The transverse drive assembly comprises an annular transmission belt, a transmission wheel assembly, a transmission wheel shaft, a transverse stepping motor, a fixed plate, a mounting plate, a slide rail, a transverse slide block and a vertical-transverse connecting block. The vertical drive assembly includes a guide post, an upper fixed plate, a lower fixed plate, a swing arm, a bearing, a vertical slide block and a vertical stepping motor. The lower end surface of the lower fixed plate is fixedly connected with the upper end surface of the vertical-transverse connecting block, the upper end surface of the lower fixed plate is fixedly connected with a spring seat internally provided with an elastic member, an eccentric wheel sleeves the output shaft of the vertical stepping motor, the inner ring of the bearing sleeves the eccentric wheel, and one end of the swing arm sleeves the outer ring of the bearing. The movement component is advantageous in that, stability of transverse movement and consistency of up-down movement of the vertical slide block are improved, and the movement component is also advantaged by high precision in vertical movement, stability in transverse movement, compact structure, and long service lifetime.
