[0002] Drilling technology has always been an indispensable part of the geological survey process, and coring is inevitably involved in the drilling process. Whether it is single-tube coring, double-tube coring or semi-closed-tube coring, workers usually need two to three people to cooperate when removing the external casing. After fixing the casing, they use a ring wrench to dismantle it. This process is time-consuming, labor-intensive and extremely inconvenient. At the same time, because the outside of the casing will be stained with plant glue, the outside is slippery and difficult to fix when taking the tube, and it often slips several times when taking the tube with a ring wrench. It is not only time-consuming and labor-intensive, but also may do useless work many times. Moreover, the above process is almost entirely manpower-based, with a low degree of mechanization.
