The reinforcing rib 113 can enhance the toughness of the first rib 111 and the second rib 112 to prevent bending after the multiple assembly parts 120 are assembled with the two-color injection molding components. The mounting seat 114 can be conveniently installed and fixed on the laser engraving base.

[0062] Example 6

[0063] like Figure 6 , Figure 7 and Figure 8 As shown, the present invention proposes a light-transmitting process of chrome-plating and then painting the surface of a two-color material.

[0064] Specifically, the outer shell 211 is in a "V" shape, and the width of the support plate 221 is adapted to the length of the slot 123 so that it can be inserted therein. At the same time, the cavity formed by the outer shell 211 and the two support plates 221 is adapted to the raised seat 124, wherein the inclined edge 126 matches the inclined edge of the outer shell 211, so that the outer shell 211 and the support plate 221 are more stable when inserted therein.

[0065] like Figure 7 and Figure 8 As shown, the outer surface of the assembly seat 121 is provided with a positioning groove located in the guide groove 125, and the inner wall of the outer shell 211 is fixedly connected with a guide bar 214, which is adapted to the guide groove 125 and plugged into the positioning groove. The support plate 221 is provided with a first assembly hole 222 and a second assembly hole 223, and the support plate 221 is provided with an assembly groove 224 on one side close to the slot 123.

The assembly groove 224 makes one side of the support plate 221 thinner, making it elastic and increasing the friction with the slot 123.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
