Abstract

A retractable lens is provided, which includes a main body, a first rotary element and a second rotary element which can rotate around the main body, a first and a second power set which can drive the first rotary element and the second rotary element, and an objective lens set. The objective lens set may correspond to the different slope rate of the first and the second slant groove at the first and the second rotary element to yield a different displacement velocity along axis direction. Therefore, the first and the second power set can aim the slope rate of the first and the second slant groove at the first and the second rotary element to set a different drive force and decelerate ratio. Further to increase the lens focusing accuracy, and reducing noise in the operation.
