Field of the Invention The present invention relates to a lens detecting device, and more particularly to a lens eccentricity detecting device and a rotating platform thereof. [Prior Art] With the rapid development of multimedia technology, digital cameras, camcorders and mobile phones with cameras are increasingly favored by consumers, and the image quality of people shooting digital φ cameras, camcorders and mobile phone cameras is higher. At the same time, demand for digital cameras, camcorders and mobile phones with cameras is increasing. Digital cameras, camcorders, and mobile phone cameras are an indispensable part of the lens. As an important part of the lens, the lens plays a key role in the image quality of the entire lens. After the lens is shaped, ground and polished, its optical axis tends to deviate from its geometric central axis. This phenomenon is called eccentricity. In theory, the eccentricity of the lens can be divided into two types, one is that the optical axis is parallel to the geometric center, and the other is the optical axis intersecting the geometric center of the lens. In fact, the eccentricity of the lens is usually a combination of the two eccentricities. There are various methods for detecting eccentricity of a lens. One of the methods for detecting eccentricity of a lens is to fix the lens to a rotating platform by means of a tweezers or the like. An eccentric detector is disposed above the rotating platform, and the rotating platform is rotated by a finger during detection. The lens eccentricity detecting method has the disadvantage that the rotating platform is often unevenly applied by the rotation of the finger, and the rotating shaft and the center axis of the lens often change due to the rotation, resulting in inaccurate measurement results. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a lens eccentricity detecting device capable of improving the accuracy of lens eccentricity measurement and a rotating platform thereof. A lens eccentricity detecting device comprising: a lens eccentricity detector, a rotating platform and a transmission structure. The lens eccentricity detector is located above the rotating platform. The transmission structure is for rotating the rotating platform. The rotating platform edge has a toothed structure, and the rotating platform is engaged with the transmission structure by the toothed structure. A rotating platform for eccentricity detection of a lens has an edge having a toothed structure through which a toothed structure can be engaged to drive the rotating platform to rotate. The edge of the rotating platform used by the lens eccentricity detecting device has a toothed structure. The rotating platform can prevent the rotation of the rotating platform by using a transmission structure having a structure that meshes with the toothed structure when performing eccentricity detection of the lens. The uneven force causes the center axis of the rotating platform and the lens to change, thereby improving the accuracy of the lens eccentricity measurement result. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. Referring to FIG. 1, a lens eccentricity detecting apparatus 100 according to an embodiment of the present invention includes a lens eccentricity detector 10, a rotating platform 20, and a 传动 transmission structure 30. The lens eccentricity detecting body 10 is located above the rotary boring platform, and the transmission structure 30 is used to sway the suspected rotation platform 2 〇 rotation. The lens eccentricity detector 10 is used for eccentricity detection of the lens 40 on the rotating platform 20, which may further include a display screen for displaying the eccentricity detection result of the mirror. The lens eccentricity detection recorded by the display screen is shown in the figure 7 200813397. It can be judged that the lens partial detector 10 adopts k, which is within the allowable target circumference. Common lens eccentricity check + word line, (4) ^财* for the Xiangzheng straight fairy board to project the collimator eyepiece view ~ focus to the first curvature center of the lens 40 to be tested, and then from the self-rotating axis, observe Shoot back the cross of f, the line, if the first-curvature nail is off the lens and adjust the rotation flat = ten sub-wires ^ rotate around a center. At this time, the rotation is focused to 20 of the mouth 40 of the lens to be tested, so that the line of the tenth line is at a fixed position, and then the m line of the objective lens is around the center of the π-curvature of a certain radius, and the cross that is reflected back is obtained by (4) eccentricity, The rotation radius can be geometrically converted, and the rotating platform 2 can be used, 4 〇, which can be placed along the center of the shovel, and the eccentricity of the eccentricity detection lens -20 is provided with a concave movement. In this embodiment, the shape of the rotating platform recess 21 is comparable to the size of the placement lens 40, preferably the sheet 40. The shape of the groove 21 is the same, and the groove 21 is sized and mirrored. The rotating platform 2 is further rotated by the platform 20 and the transmission structure 30 is φ such as the tooth structure 22. , the structure of the transmission structure 3〇, the transmission structure 3 can be specifically a gear machine=about the motorized structure 30 and the rotating platform 2〇i worm mechanism or Rack mechanism. In the transmission mechanism, the planes may together form a plane gear mechanism or space and power, and the space gear mechanism refers to a motion or power that transmits motion between two parallel shafts.
