Technical Field

[0001] This utility model relates to the field of thread tightening equipment technology, specifically a thread tightening assembly anti-rotation device. Background Technology

[0002] Threaded connections are a method of fixing or connecting two or more components through the engagement of internal and external threads. They utilize the helical characteristics of threads, rotating the thread of one component to move the relative position of another, thus achieving the purpose of fastening or connecting. Threads can be formed by cutting or rolling equidistant helical lines on the surface of a cylinder or cone.
