[0002] Most of the existing ordinary nuts are engaged with the external threads of the stud to be connected through the internal threads provided on the nuts. By rotating the nut, the nut moves in a helical mating motion along the stud to be connected until it is screwed to the locking position; when disassembling, the nut is rotated in the reverse direction, and the nut moves in a helical mating motion along the stud to be connected until the internal threads of the nut are completely disengaged from the external threads of the stud to be connected.

The threaded block is rotatably connected to the nut body through an axially arranged rotating shaft and swings between a clamping position and an unfolded position. In the clamping position, the threads of the threaded block can be threadedly connected with the threads of the stud to be connected. In the unfolded position, the threads of the threaded block yield to the threads of the stud to be connected to allow the stud to pass through, so as to realize the quick assembly and disassembly of the nut and the stud to be connected. The structure is very simple and the function is reliable. When in use, the nut may become loose due to vibration, temperature change or load variation. This will lead to unstable connection and may affect the safety and performance of the equipment.
