A hanging groove 5 is provided on the upper back of the housing 1. The hanging groove 5 consists of a U-shaped groove 6 and a fan-shaped groove 7, the fan-shaped groove 7 being large enough to accommodate one finger. A plug-in groove 8 communicating with the hanging groove 5 is provided on the top of the housing 1. An extension hanging plate 9 is inserted through the plug-in groove 8. The extension hanging plate 9 includes a plug-in rod 10 adapted to the plug-in groove 8, an elastic buckle 11 integrally formed on the plug-in rod 10, a support base 12 integrally formed on the upper end of the plug-in rod 10, and a hanging part 13 integrally formed on the upper end of the support base 12. A snap-fit ​​post 14 adapted to the U-shaped groove 6 is provided at the upper end of the elastic buckle 11, a hanging hole 15 is provided at the upper end of the hanging part 13, and a raised flange 16 is integrally formed on the back edge of the plug-in rod 10. When the extension plate 9 is inserted into the insertion slot 8, the snap-fit ​​post 14 snaps into the U-shaped groove 6, and the support base 12 is supported on the upper surface of the housing 1.

[0017] Preferably, the lower end of the clamping column 14 is provided with a guide slope 17. The guide slope 17 facilitates the insertion of the clamping column 14 into the insertion slot 8, and when the U-shaped slot 6 of the shell 1 is hung on the cabinet body, the hanging column on the cabinet body can more easily push the clamping column 14 away.
