as shown in fig. 10 and 12, one end of the decoration 20 away from the extension section is pressed downward in the direction of the arrow, the extension section 221 is tightly attached to the connecting body 13, the positioning hole 217 of the main body 21 is aligned with the positioning post 218 on the main body 10 and is sleeved on the positioning post 218, so that the decoration 22 and the main body 10 are completely positioned, at this time, the decoration 22 is accommodated in the installation groove 12 to encapsulate the installation groove 12, the decoration wall 220 is exposed out of the outer surface 102, and the surface of the decoration wall 220 can be located on the same plane as the outer surface 102. In this process, if the main body 21 is shifted, the two guide strips 109 abut against the guide surfaces, so that the positioning posts 218 can be aligned with the positioning holes 217 when the main body is corrected in time.

Finally, the positioning body 222 is fixed to the connecting body 13 after being hot-melted by a hot melting method, and the positioning column 218 is fixed to the main body 21 after being hot-melted, so that the decoration 20 is completely fixed to the body 10, and the requirements of structural reliability and complete appearance of the shell are met. In order to fix the decoration 20 to the main body 10 more firmly, a plurality of positioning holes may be disposed on two sides of the main body 21, and a heat-melting column may be disposed on the inner surface 101 of the main body 10 corresponding to the positioning holes, and fixed to the main body 21 after heat-melting.

The foregoing is a preferred embodiment of the embodiments of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the embodiments of the present invention, and these modifications and decorations are also regarded as the protection scope of the embodiments of the present invention.
