ATTACHMENT DETACHING DEVICE
To provide an attachment detaching device capable of easily attaching an attachment without using an expansion tool.SOLUTION: An attachment detaching device 1 is provided with a first hook member 2 and a second hook member 3 configured to be rotatably held to each other through a rotational axis 11. The second hook member 3 is provided with: a pair of second plates 33 arranged with a space apart in an axial direction of a second arm joint pin 31; a second concave part 34 formed on a second plate 33; and second closing means 36 to open/close an opening 34A of the second concave part 34. The opening 34A of the second concave part 34 is positioned on an extended line connecting a center of the second arm connection pin 31 and a center of the second concave part 34. That is, the opening 34A is positioned in a lower part of a drawing and the second concave part 34 is opened downward. The second plate 33 is provided with a stopper part 35 extending from an outer end part 34C to a side opposite to an inner end part 34B.SELECTED DRAWING: Figure 1
【課題】伸縮具を用いる必要がなく、容易にアタッチメントを装着可能なアタッチメント着脱装置を提供する。【解決手段】アタッチメント着脱装置１は、回動軸１１を介して互いに回動自在に保持される第１フック部材２および第２フック部材３を備える。第２フック部材３は、第２アーム連結ピン３１の軸方向に離間して設けられる一対の第２プレート３３と、第２プレート３３に形成された第２凹部３４と、第２凹部３４の開口３４Ａを開閉する第２閉鎖手段３６とを備える。第２凹部３４の開口３４Ａは、第２アーム連結ピン３１の中心と第２凹部３４の中心とを結ぶ線の延長線上に位置する。すなわち、開口３４Ａは図面下方に位置し、第２凹部３４は下方に開口する。第２プレート３３には、外端部３４Ｃから内端部３４Ｂとは反対側へと延びるストッパ部３５を備える。【選択図】図１
