1. A linkage apparatus, wherein the linkage apparatus is used in a camera module with continuous zooming, and the linkage apparatus comprises:
a base;
a first carrier;
a second carrier, wherein the first carrier and the second carrier are slidably connected to the base;
a first positioning element disposed on the base;
a first sensing element;
a second positioning element, wherein the first sensing element and the second positioning element are disposed on the first carrier; and
a second sensing element is disposed on the second carrier,
wherein the first sensing element is disposed opposite to the first positioning element, to detect a location of the first carrier relative to the base; and
the second sensing element is disposed opposite to the second positioning element, to detect a location of the second carrier relative to the first carrier.
