管钳等钳类工具,是反钻具最常使用的一些工具。然而,往往由于扭矩过大,超过钳子的承载能力,而使钳子大量损坏,甚至还会引起人身或孔内事故。为此,我们设计制造了一种专用工具—反钻具安全扳手,用以代替钳类工具。其结构见下图。使用时,将四方钻杆9插入扳手中心轴8四方孔内,钻杆下边通过锁接头与处理事 Pipe clamp pliers and other tools, is the most commonly used tool for anti-drilling tools. However, it is often caused by excessive torque exceeding the carrying capacity of the pliers, which can cause extensive damage to pliers and can even cause personal or intracranial accidents. To this end, we designed and manufactured a special tool - anti-drill safety wrench, to replace the pliers tools. The structure shown below. When in use, the square drill pipe 9 is inserted into the square hole of the wrench center hole 8, the lower part of the drill pipe is connected with the handle
