[0056] 2. After the guide protrusion 11 is caused to be out of the guide recess 21, there is a gap between the inner side surface of the tip cap 2 and the outer side surface of the tip member 1, and at this time, the tip cap 2 is disassembled along the axial direction, so that the contact area between the inner side surface of the tip cap 2 and the outer side surface of the tip member 1 can be effectively reduced, and then the frictional force that needs to be overcome in the process of disassembling the tip cap 2 can be reduced.
