[0002] In the construction of inclined shafts and vertical shafts of pumped-storage power stations, anti-lift drills and drill pipes play a vital role. At present, threaded connections are generally used between drill pipes to achieve connection and fixation. However, threaded connections require tools to be tightened, which not only increases the complexity of construction, but also prolongs the operation time. In addition, during the process of driving the drill pipe through threaded locking, the threaded part is easily damaged. Once the thread is damaged, the structural integrity and connection reliability of the drill pipe will be seriously affected, and even the entire drill pipe device will be unable to continue to be used, increasing construction costs and maintenance difficulties. The disassembly process of the drill pipe threaded connection is also cumbersome, requiring tools to reversely loosen the thread, but damaged threads will make the drill pipe difficult to disassemble, increasing the work intensity and safety risks of construction personnel.

When it is necessary to separate the first drill rod 1 and the second drill rod 2, the first connecting mechanism 5 and the second connecting mechanism 6 are directly disassembled, the first clamping link assembly 32 is pulled out of the second drill rod 2, and the second clamping link assembly 42 is pulled out of the first drill rod 1, and the first drill rod 1 and the second drill rod 2 are separated synchronously.
