[0051] The special-shaped connecting column 10 and the badge top cover 2 are an integrated structure. The end of the special-shaped connecting column 10 close to the badge top cover 2 is chamfered, the middle position is cylindrical, and the other end is semi-conical. The diameter of the semi-conical and cylindrical connection position is smaller than the diameter of the middle position.

The limiting arc piece 8 is fixed to the bottom of the rectangular groove 7, and its top tends to bend inwards. When the badge base 1 is inserted from top to bottom into the surface of the badge top cover 2, the bottom of the card piece 9 contacts the rounded corner of the limiting arc piece 8 that is bent inwards, and the limiting arc piece 8 is squeezed by its bottom to generate The card plate 9 is deformed so that the limiting arc piece 8 is offset to the side away from the card plate 9. At this time, the card plate 9 reaches the bottom of the rectangular groove 7, and the card ball 17 on the inner wall of the rectangular groove 7 is inserted into the fixing groove 16 to fix the position of the card plate 9. It should be noted that the arc of the card plate 9 bent outward is the same as the arc of the limiting arc piece 8 bent inward, and the inner wall of the card plate 9 and the outer wall of the limiting arc piece 8 are in contact with each other, which further increases the stability of the connection between the badge base 1 and the badge top cover 2.
