In the above scheme, the buckle structure is designed to be fixed with the display panel 2 and the display plate 3 respectively, so that the assembly is relatively simple.

[0033] As shown in Figures 4 to 6 some embodiments, the bottom of the support part 41 is further provided with a plurality of insertion tabs 43 and a limiting buckle 44. Specifically, the plurality of insertion tabs 43 are uniformly arranged in a ring shape on the bottom of the support part 41, and the limiting buckle 44 is arranged between any two adjacent insertion tabs 43. The clamping hook of the limiting buckle 44 faces the outer side of the insertion tab 43, and is used for cooperating with the inner wall of the encoder 6 to limit the support part 4 from being separated from the encoder 6. Specifically, the support part 41 is inserted into the hollow cavity 61 of the encoder 6 through the insertion tabs 43, and is clamped together with the inner wall of the encoder 6 through the limiting buckle 44, so as to limit the rotation of the support part on the encoder 6, and realize the overall assembly.
