[0017] The following is a further detailed description through specific embodiments:

[0018] The reference numerals in the accompanying drawings of the specification include: upper case 1, panel 2, display frame 3, display screen 4, light guide plate 5, main board 6, driven wheel 7, battery 8, lower case 9, bottom cover 10, sink 11, ratchet 12, buckle 13, card slot 14, buzzer 15, annular groove 16, annular protrusion 17.

[0019] As shown in the Figures 1-5 accompanying drawings, this embodiment shows a radio wave timer, including an upper case 1, a panel 2, a display frame 3, a display screen 4, a light guide plate 5, a main board 6, a driven wheel 7, a battery 8, a lower case 9 and a bottom cover 10; wherein, the panel 2 is snap-connected to the display frame 3, and the display screen 4, the light guide plate 5 and the main board 6 are all arranged in the display frame 3. The display screen 4, the light guide plate 5 and the driven wheel 7 are respectively connected to the main board 6; the upper case 1 is sleeved outside the display frame 3, and the upper case 1 is rotatably arranged relative to the display frame 3.

[0020] Among them, a sink 11 is arranged at the top inside of the upper case 1, and the panel 2 is arranged in the sink 11. In this way, the upward movement of the upper case 1 is restricted by the panel 2, and the downward movement of the upper case 1 is restricted by the lower case 9.

[0021] The inner wall of the upper shell 1 is provided with teeth 12, and the teeth 12 mesh with the driven wheel 7. The lower shell 9 and the bottom cover 10 are detachably connected, and the lower shell 9 and the display frame 3 are detachably connected. Specifically, in this embodiment, the lower shell 9 and the bottom cover 10 are connected by screws, and the lower shell 9 and the display frame 3 are also connected by screws. The battery 8 is used to provide power to the display screen 4 and the mainboard 6.

[0022] The working principle of the radio-controlled timer of this embodiment is to rotate the upper shell 1 and use the teeth 12 on the inner wall of the upper shell 1 to drive the driven wheel 7 to rotate to adjust the time. This changes the original method of adjusting the time by pressing or rotating the button, and can effectively avoid the confusion of the adjusted time caused by accidental touch.

[0023] Specifically, a buckle 13 is provided at the bottom of the panel 2, and a slot 14 is correspondingly provided at the display frame 3, and the buckle 13 is engaged with the slot 14.
