[0001] The invention relates to the field of meat grinders, and in particular to a meat grinder and a use method thereof. Background Art

[0002] Meat grinders are very common tools in our daily lives. Food can be ground into small pieces by meat grinders, which is convenient for users to process food later. Meat grinders are closely related to people's lives. They are widely used in industries such as meatballs, dumpling fillings, pet food, and other meat products. The cup of the meat grinder is made of glass or food-grade stainless steel, which does not pollute the processed materials and meets food hygiene standards. Nowadays, people's living standards are gradually improving, and there are more diverse demands for processed food. Therefore, meat grinders have become a must-have small household appliance in the home. In order to improve the user experience, meat grinders are gradually developing in the direction of miniaturization and intelligence.

[0003] However, when the food to be minced is put into the meat grinder, the spring inside the chopping knife prevents the chopping knife from moving completely downward. The food can only enter the bottom of the meat grinder through the gap between the chopping knives, which also leads to the problem that the main unit cannot be installed in place. Summary of the invention

[0004] In view of the above problems, the present invention provides a meat grinder and a method of using the meat grinder, which can avoid the main machine being unable to be normally installed due to too much food.

[0032] like Figure 4 As shown, the shredder 3 includes a knife column 301 and a blade 302. The blade 302 has three blades, which are fixed to the lower outer side of the knife column 301 from top to bottom. The top center of the knife column 301 has an upward five-pointed star-shaped protrusion as a second clamping portion 303. The diameter of the second clamping portion 303 is smaller than the diameter of the knife column 301. Figure 5 As shown, the knife column 301 has a cylindrical cavity inside, and a spring limiting mechanism 304 is provided at the top of the cavity. A spring is fixed in the spring limiting mechanism 304, and a top plate 305 is fixedly connected to the lower end of the spring. The top plate 305 can slide up and down along the cavity. Figure 6 As shown, a first cross-shaped snap-in groove 306 is provided at the center of the bottom surface of the knife column 301. The first snap-in groove 306 penetrates from the bottom surface of the knife column 301 into the cavity. The diameter of the first snap-in groove 306 is smaller than the diameter of the cavity. Figure 7 and Figure 8 As shown, the first clamping portion 201 can slide along the first clamping groove 306, and the rotating fixed shaft 2 can extend into the cavity along the first clamping groove 306. The rotating fixed shaft 2 can press against the top plate 305 to compress the spring upward, so that the first clamping portion 201 is located in the cavity, and the shredder 3 can rotate with the rotating fixed shaft 2 as the axis.

[0033] like Fig.12As shown, the cup cover 5 has a third through hole 501 at the center thereof, and has a second handle 502 on both sides thereof that can correspond to the cup body 1.
