[0025] In the present embodiment, in order to realize the connection and installation between the front cover shell and the rear cover cover, a matching concave-convex structure is arranged between the rear end face of the front cover shell and the front end face of the rear cover shell, a plurality of rear convex connecting columns 11 are arranged in the front cover shell, and a front convex connecting column 21 which is buckled with the rear convex connecting column and connected with the rear convex connecting column by bolts or screws is arranged in the rear cover shell.

[0026] In this embodiment, the rear end face of the front cover shell is provided with an annular rear protrusion 12, the front end face of the rear cover cover is provided with an annular rear recess 22 for embedding the annular rear protrusion, and the inner wall of the rear cover cover is provided with limit plates 23 protruding forward in the circumferential direction for limiting the annular rear protrusion, so that the annular rear protrusion is limited in the annular rear recess through the cooperation of the limit plate and the rear cover cover, thereby ensuring the stability of the connection between the front cover shell and the rear cover when installed.

[0027] In this embodiment, in order to better complete the connection with the plastic doll, the front convex portion is rectangular and has positioning ridges 43 on all four sides, and the rear end face of the plastic doll is provided with a connecting recess for cooperating with the front convex portion and the positioning ridges, so as to facilitate the plastic doll to be inserted into the front convex portion and positioned to prevent rotation.

[0028] In this embodiment, a decorative panel 5 made of acrylic material is provided on the front side of the rear side wall of the cavity. The decorative panel can be made of a transparent acrylic panel and is bonded to the front side of the cavity. The decorative panel is provided with an escape opening for the front protrusion to pass through, so as to facilitate the installation of the decorative panel.

[0029] In this embodiment, in order to better form the concave cavity and facilitate the production of various components, an annular opening 13 is provided on one side of the front cover shell, and a plastic cover 4 for forming the concave cavity is connected to the rear side of the annular opening in the front cover shell, and the front protrusion is arranged in the plastic cover and is integrally formed.

[0030] In this embodiment, in order to better complete the connection between the plastic cover and the front cover shell, connecting blocks 44 are arranged at intervals around the circumference of the plastic cover, and positioning columns 14 that are tightly matched with the connecting blocks are arranged in the front cover shell.

[0031] In this embodiment, the rear cover is provided with a battery compartment 24, and the front side of the battery compartment is provided with a limiting structure 25 for supporting the rear end of the plastic cover, which helps to prevent the plastic cover from loosening after the front cover shell is connected to the rear cover.

[0032] In this embodiment, a liquid crystal display screen 15 is disposed on the other side of the front housing, and a circuit board electrically connected to the liquid crystal display screen is disposed inside the front housing, so that information such as time and temperature can be displayed on the liquid crystal display screen.
