[0002] Mechanical watches are the most common type of watches, which are divided into manual-winding and automatic-winding watches. Both of these mechanical watches are powered by the spring in the movement, which drives the gears and then pushes the hands, but the power source is different.

[0003] Deficiencies of the existing technology: Under the existing technology, during the production and processing of mechanical watches, workers need to perform glue dispensing operations on the dial. The purpose of glue dispensing is to strengthen the adhesion between the dial and the frame and other components. Currently, when dispensing glue, workers usually need to grasp the dial with one hand and perform glue dispensing operations with the other hand. This operation results in poor stability of the dial, affects the final glue dispensing effect, and is also inconvenient for workers to operate. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] The present invention can be used to fix the rotation of the handle by hand so that the rotating plate and the guide blade can rotate around the axis of the fixed shaft as a whole. During the rotation of the guide blade, the guide blade squeezes the guide arc surface on the connecting rod, so that the connecting rod slides synchronously along the fixed frame, and the compression spring is stretched under the pulling of the extension plate, and the three clamping plates move in the directions away from each other. The staff places the dial of the mechanical watch on the top of the upper mounting plate. The staff then rotates the rotating handle in the opposite direction, and the rotating plate and the guide blade can rotate around the axis of the fixed shaft as a whole in the opposite direction. The elastic force of the compression spring drives the three clamping plates to move in the directions close to each other, and the clamping arc surfaces of the three clamping plates fit with the dial to clamp the dial in position. The present invention solves the shortcomings of the prior art and can effectively clamp and position the dial when performing glue dispensing operation on the dial. Compared with the operation method of grasping the dial with one hand and dispensing glue with the other hand, the stability of the dial is greatly improved, thereby optimizing the glue dispensing effect. In addition, the staff only needs to tighten or release the clamp by tightening the rotating handle by hand, which is simple and convenient to operate, and further provides convenience for the staff.
