New description: [New technical field] This creation is about the shifting device in barbecue equipment, especially one that can be clamped and assembled to the barbecue rotary motor, and has an adjustable mechanism to adapt to different specifications. The grille rotates the motor's shifting device. [Prior Art] • Pressing 'Because the Chinese are in a holiday break', such as short-term travel or outings, most of them carry out barbecue activities. Therefore, in order to improve the quality of the above-mentioned barbecue activities, the industry has gradually developed various barbecue utensils. To meet the needs of users' and increase the convenience of users in the barbecue activities. In the conventional barbecue activities, in order to prevent food (such as sausage) from being scorched, or only partially cooked, it is difficult to swallow food, etc., users often need to constantly flip food to make various parts of the food It can be evenly baked. However, the above-mentioned methods will cause the user to pay attention to the familiarity of the food, and • f will always lose food, so that the system can not relax, or chat with others, affecting leisure activities _ quality. Therefore, in order to solve the above problems, a manufacturer adds a barbecue rotary motor to the original barbecue appliance, as shown in the figure i and the figure, the aforementioned barbecue appliance i includes a metal barbecue rack 1 and a barbecue body 12 And the barbecue rotary motor 14, wherein the metal grilling gorge 1 is composed of a metal frame m and a two-bar body 1 〇 3 jin, the metal frame 1 〇 1 domain has a storage space for the user The food to be grilled is placed therein, and the two sides are respectively provided with the respective body.
