套管拆卸工具及套管拆卸方法
摘要：
本发明提供一种套管拆卸工具，其可以不损坏套管而将其从丝锥上容易地拆下。套管拆卸工具(4)具有第1接合部件(5)和第2接合部件(6)。第1接合部件(5)形成为大致圆筒状，具有第1抵接面(51)和内螺纹部(52)。第1抵接面(51)与套管(1)的凸缘(12)上的一个环状面在整个圆周上抵接。内螺纹部(52)从第1抵接面沿轴向凸出地设置。第2接合部件(6)形成为大致圆筒状，具有第2抵接面(61)和外螺纹部(62)。第2抵接面(61)与凸缘(12)上的另一个环状面在大致整个圆周上抵接。外螺纹部(62)在外周面的第2抵接面(61)侧形成。
摘要（英）：

The object of the invention is to provide a sleeve removal tool that is able to easily remove a sleeve from a tap without damaging the sleeve. The sleeve removal tool (4) has a first fastening member (5) and a second fastening member (6). The first fastening member (5) has a first contact surface (51) and an inner screw section (52), and is formed in a cylindrical shape. The first contact surface (51) comes in contact with the flange (12) of the sleeve (1) all around one ring shaped surface. An inner screw section (52) is provided such that it protrudes in the axial direction from the first contact surface. The second fastening member (6) has a second contact surface (61) and an outer screw section (62), and is formed in a cylindrical shape. The second contact surface (61) comes in contact with all around another ring shaped surface of the flange (12) peripherally. The outer screw section (62) is formed on one side of the second contact surface (61) of the outer circumference surface.
