Technical Problem

但是数控车床整体是封闭的，车床尾座部位空间狭小，难以布置手摇退却装置，相关技术中，一般采用一块钢板顶着顶尖背部，用榔头敲击钢板另一头，直至把顶尖顶出来，容易对锥柄造成损坏，或者是用顶尖专用扳手卡住顶尖背部的槽子，旋拧完成拆卸，扳手只能对特定尺寸的锥柄进行拆卸，通用性差

Benefits of technology

[0016]本实用新型的有益效果在于：提供一种拆卸工具，该拆卸工具通过设置拆卸件，拆卸件能够沿待拆卸刀具的锥柄的径向插入待拆卸刀具与车床尾座的连接处的缝隙，并且拆卸件分别与待拆卸刀具和车床尾座抵接，以使得待拆卸刀具向远离车床尾座的方向移动，沿拆卸件拆插入的方向，拆卸件的厚度逐渐减小，当拆卸件沿待拆卸刀具的锥柄的径向插入待拆卸刀具与车床尾座的连接处的缝隙时，在拆卸件与待拆卸刀具的抵接处，驱动拆卸件的径向力转换为轴向的支撑力，进而支撑待拆卸刀具向远离车床尾座的方向移动，实现拆卸，该拆卸工具结构简单，不易损坏锥柄，通用性强。
