摘要： PROBLEM TO BE SOLVED: To solve such a problem that when using the same socket for a long period of time in a power tool such as an impact wrench, a fitting part of a square drive of an anvil and a square hole of the socket is worn gradually, so that a connecting pin receives rotational striking force of the anvil, namely, the connecting pin continually receives the rotational striking force to cause the connecting pin to be plastically deformed, and thereby the connecting pin cannot be removed from a through-hole of the socket, resulting in causing a risk that the socket cannot be replaced.SOLUTION: According to a present invention, a material of a connecting pin is formed of an elastic body, and thereby even when the fitting part of the square drive of the anvil and the square hole of a socket is worn out and the rotational striking force is applied to the anvil, the connecting pin is elastically deformed. Consequently, if tightening work of a bolt, etc., is finished and the rotational striking force is not applied, the connecting pin returns to an original shape, and the socket can be replaced.
摘要翻译：要解决的问题为了解决这样一个问题，当在诸如冲击扳手的电动工具中长时间使用相同的插座时，砧座的方形驱动的装配部分和插座的方孔是逐渐磨损，使得连接销接受砧座的旋转打击力，即，连接销不断接收旋转打击力，使连接销塑性变形，从而连接销不能从通孔中移除导致插座不能更换的风险。解决方案：根据本发明，连接销的材料由弹性体形成，从而即使当方形驱动的配合部分砧座和插座的方孔磨损，旋转打击力施加到砧座上，连接销弹性变形。因此，如果螺栓等的紧固工作完成并且不施加旋转打击力，则连接销返回到原来的形状，并且可以更换插座。
