Description

【Technical field】 [0001] The invention relates to the technical field of screws, in particular to the technical field of convenient hand-tightened screws. 【Background technique】 [0002] Screws are commonly found in machinery, electrical appliances, and buildings. They are generally made of metal or plastic and are cylindrical in shape. The grooves engraved on the surface are called threads. The main function of the screw is to join two objects, or to fix the position of an object. Screws can usually be removed and retightened at will without loss of efficiency. Generally, the top of the screw has a large diameter, and the common ones are round, square or regular hexagonal. If the top is regular hexagonal, you can use a wrench to turn the screw. If the top is round, there will be grooves on the front of the top for easy use. screwdriver turns the screw. The most common grooves are one-shaped, cross-shaped and square, and there are other shapes. In some special occasions,...
