Iron pans are traditional kitchen utensils for people to cook food. They generally do not contain toxic substances and will not oxidize. In the process of stir-frying and cooking food, there are very few dissolved substances in the iron pot. Even if there is iron dissolved out, it is also good for the human body. Cooking in the iron pot is the most direct way to supplement iron. The main types are India pot, ear pot, pan, oil pan, pancake pan. In the process of cooking dishes in an iron pan, a small amount of iron will dissolve in the food, supplement iron for people, supplement the iron-deficient part of the food itself, and play a role in preventing iron-deficiency anemia. Can increase the amount of iron in a person's diet. Therefore, as far as the prevention and treatment of iron deficiency anemia is concerned, cooking in an iron pan is beneficial to health.
new type of screw includes a fixing object and a screw body composed of a nut, a fixing piece and a screw rod. An outer gear ring is fixedly sleeved on the fixing piece, and a support plate is arranged on the lower side of the outer gear ring. The upper side of the support plate is connected with a mounting frame through an adjustment mechanism, the inside of the mounting frame is connected with the outer gear ring through an anti-drop mechanism, and a mounting plate is fixedly connected to the side of the support plate close to the fixed object, and the mounting plate is clamped The coupling mechanism is connected to the fixture.
The fastener with a nut is composed of a polygonal nut and a bolt. The bolt includes an integral screw rod and a screw head. The fastening surfaces of the nut and the screw head are polygonal. There are external threads on the periphery of the screw, and the main point is that the axial three-dimensional shape of the nut and the screw head is an odd-numbered truncated cone, and the odd-numbered angle is an arc angle, and each arc angle corresponds to an elastic surface.
