    • PROBLEM TO BE SOLVED: To provide a key extraction device capable of easily executing extraction work of a headed key by comparatively small force.SOLUTION: Since a hydraulic device is constituted of a hydraulic pump, a hollow type hydraulic cylinder with a male screw part inserted into an inside through-hole and a hose for connecting the hydraulic pump and the hydraulic cylinder, only a key extraction main part, a holding cylinder and the hollow hydraulic cylinder are arranged on the pulley side for removing the headed key, and since the hydraulic pump for adding pressing force is extended by the hose of a predetermined length and can be arranged in a separate position easy in pressing work, even if a rotary apparatus including, for example, a pulley is installed at an elevated spot with the headed key, the extraction work is preferable only by pressing a handle lever of the hydraulic pump provided in a place separate from it, and the work can be executed in a place such as on the ground and a work desk, and the extraction work of a key can be efficiently and smoothly executed even by little force.
    • 要解决的问题:提供一种能够通过相对小的力容易地执行头部钥匙的抽取工作的钥匙提取装置。解决方案:由于液压装置由液压泵构成,插入有外螺纹部的中空型液压缸 用于连接液压泵和液压缸的内部通孔和软管中,只有钥匙提取主体部分,保持筒和中空液压缸被布置在滑轮侧,用于移除头部钥匙,并且由于液压 用于增加按压力的泵通过预定长度的软管延伸,并且即使包括例如滑轮的旋转装置安装在带有头部的高架位置上,也可以被布置在易于按压工作的单独位置, 仅通过按压设置在与其分开的位置的液压泵的手柄杆来进行提取工作,并且可以在诸如纸巾等的地方进行加工 nd和一张办公桌,一键的提取工作即使在很小的力量下也能高效,顺利地执行。
