[0028] This embodiment mainly describes the structure of the cup cover, which is as follows:

[0029] The assembly structure of the cup cover includes an inner cover 1 and an outer cover 2 sleeved on the inner cover 1. The inner cover 1 is made of plastic, and the outer cover 2 is made of metal. At least one connecting piece 3 is arranged between the inner cover 1 and the outer cover 2. The connecting piece 3 is made of metal and has a C-shape.

[0030] The connecting piece 3 is tightly pressed between the inner cover 1 and the outer cover 2 , and the connecting piece 3 is interference fit with the outer wall of the inner cover 1 and the inner wall of the outer cover 2 .

[0031] A limiting portion for limiting the movement of the inner cover 1 is provided between the connecting piece 3 and the inner cover 1 .

[0032] The bottom end of the outer cover 2 is bent inward to form a limiting ring 21 . After the connecting piece 3 is placed in the outer cover 2 , the connecting piece 3 is stuck on the limiting ring 21 to prevent the connecting piece 3 from being separated from the outer cover 2 .
