Core disassembling device

A core disassembling device and a capacitance pen, the capacitance pen comprising a core to transmit capacitance signals, the core disassembling device comprising:

• an opening-closing box housing having an upper housing and a bottom housing, one side of the upper housing is connected with one side of the bottom housing to permit opening and closing of the opening-closing box housing, a side wall of the upper housing having a first notch, a side wall of the bottom housing having a second notch;
• wherein the opening-closing box housing is made of an elastic material;
• the core of the capacitance pen is placed in the first notch or the second notch when the opening-closing box is opened;
• the first notch and the second notch constitute a circle-shaped holding hole when the opening-closing box is closed;
• and a diameter of the circle-shaped holding hole is smaller than a diameter of the core of the capacitance pen, so that the core is pinched by the opening-closing box and can be drawn out from the capacitance pen via the opening-closing box after the opening-closing box is closed.
