[0002] With the high speed development of glasses processing industry in recent years, the current market gradually improves the requirement for glasses lens processing precision, thereby gradually improves the requirement for glasses lens shape extraction. Glasses lens shape extraction is divided into two types, one is optical scanner using image extraction technology to directly scan glasses lens contour shape, another is mechanical scanner scanning the inner shape of glasses frame through mechanical arm.

[0003] For mechanical scanner, the traditional glasses frame inner shape scanning structure pushes the glasses frame through the push rod in its structure to make it clamp the mirror seat, and then two magnetic support blocks are used to resist the two corners of the glasses frame. Then the knob on the mirror seat is rotated to adjust the position of the glasses frame to meet the scanning conditions of the glasses frame. In the whole process, the glasses frame is only stressed through the contact point of the same horizontal plane to achieve the effect of clamping the glasses frame. Neither the actual effect nor the theoretical analysis can guarantee that the glasses frame is clamped tightly. If the glasses frame shakes during the scanning of the inner shape of the glasses frame, it will cause abnormal scanning, thereby causing the glasses lens to be unable to be processed. And the operation is inconvenient and low in efficiency. UTILITY MODEL CONTENT
