[0003] When dismantling the steel nails, it is difficult to recover the steel nails on the coal wall. It is necessary to arrange special personnel to stand on the ladder and use wrenches, pliers and other tools to repeatedly hit the steel nails, which not only increases the workload of employees, but also increases the risk of high-altitude operations. It is also easy to cause injuries such as hitting hands when dismantling the steel nails, and it is also easy to cause the steel nails to be severely deformed and cannot be reused. Some steel nails are too firmly installed to be removed, resulting in a waste of steel materials. The steel nails that cannot be removed are very likely to pop out when the coal machine is cutting coal, causing personal injury or equipment damage, leaving great safety hazards. Therefore, a tool for removing steel nails in underground coal walls is proposed to address the above problems. Utility Model Content
