DETAILED DESCRIPTION

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] like Figure 1 , Figure 2 , Figure 3As shown, a rotary frame of a vacuum coating machine for cutting tools includes a main frame body, which includes a fixed gear 1 and a revolving gear 2 above the fixed gear 1. The revolving gear 2 can be driven by a driving motor. The revolving gear 2 is rotatably connected to a plurality of planetary gears 3. The planetary gears 3 are meshed with the fixed gear 1. When the revolving gear 2 rotates, the planetary gears 3 revolve and rotate. The revolving gear 2 is fixedly connected to a plurality of connecting rods 4. The end of the connecting rod 4 away from the revolving gear 2 is fixedly connected to a top plate 5.
