[0002] A nut is a fixing tool with a hole in the center and threads on the inside of the hole. Nuts are often used together with screws of the same size to fix the relevant joint parts. If the nut is loosened due to environmental factors such as vibration, glue or pins can be used to further reinforce the relevant parts. Nuts are mostly hexagonal, followed by square. Currently, nuts are mainly used in conjunction with bolts to lock and fix objects. Due to the simple structure of nuts and the lack of protective auxiliary devices, nuts can be easily disassembled when subjected to external forces for a long time, resulting in property losses.

[0003] At the same time, a nut with application number 202022205277.1 is provided with a handle on the nut body, which is connected to the nut body to form a connection part, and the connection part is easy to break. When internally fastening on mechanical equipment, after putting the nut into the groove or concave space of the equipment, you can hold the handle with your hand or clamp the handle with other auxiliary devices to fix the position of the nut, and then tighten it with bolts. It is not easy to loosen after fastening. After fastening, the handle can be broken off, which does not occupy the installation position of other parts on the equipment and does not affect the appearance of the equipment.
