The first lens cone comprises at least one guide groove; the second lens cone is sleeved at the first lens cone and comprises at least one opening, and the opening comprises at least one groove; and the third lens cone is sleeved at the second lens cone and comprises at least one guide pin and at least one accessory structure, wherein the guide pin moves in the guide groove, and the accessory structure moves along the groove of the opening.

Description

technical field [0001] The invention relates to a lens mechanism, in particular to a lens mechanism applied to a photography device. Background technique [0002] With the advancement of technology, digital camera mechanisms have been widely used in various digital products, such as digital cameras, digital video cameras, mobile phones, personal digital assistants (PDAs), and the like. The digital camera mechanism includes a lens mechanism and an image sensor. The lens mechanism can focus the image on the image sensor, and then the image sensor converts the optical image signal into an electronic signal. [0003] The traditional lens mechanism usually includes a cam barrel and a lens frame. The cam barrel and the lens frame have guide grooves and guide pins respectively. The guide pins can move along the guide grooves to control the relative positions of the lens frame and the cam barrel. , to reach the zoom function. However, when the traditional lens mechanism is droppe...
