The present invention provides a lens displacement device, applicable for moving micro image-capturing module lens, wherein the lens displacement device comprises: a lens slide base, a first hollow magnet, a hollow magnetic conducting plate, a second hollow magnet and a hollow coil. A first magnetic pole side of the hollow magnetic conducting plate is magnetically connected to the first hollow magnet, and a second magnetic pole side of the hollow magnetic conducting plate is magnetically connected to the second hollow magnet, which combined to form a magnetically connected assembly. The hollow coil is placed at the outer or inner perimeter of the magnetically connected assembly, and the hollow coil surrounds the magnetically connected assembly and they have a gap in-between them to allow for sliding. Herein the lens slide base rigidly connects the first hollow magnet of the magnetically connected assembly or the hollow coil.
