1. A connectable marker pen, comprising a body and a pen cap; wherein,
the pen cap is provided on at least one end of the body;
an exterior of the pen cap is provided with one or more protrusions, and the one or more protrusions include at least one first protrusion and at least one second protrusion; and
the at least one second protrusion has a groove that mates with the at least one first protrusion;
wherein both the at least one first protrusion and the at least one second protrusion are provided on at least one surface of the exterior of the pen cap; wherein
the pen cap is provided with a limiting structure and a second elastic component;
the limiting structure is configured to control a state of the one or more protrusions; and
when the limiting structure is in a non-limiting state, in response to the one or more protrusions being subjected to an action of pressure, the one or more protrusions move along an axial direction of the one or more protrusions under the action of the pressure and such that the second elastic component undergoes an elastic deformation.
