Touch control pen for a portable electronic device

摘要

A touch control pen for a portable electronic device includes a resilient positioning sleeve sleeved sealingly on an elongate main body and disposed adjacent to a head end of the main body. When the touch control pen is inserted into a slot defined by a looped surrounding wall of a housing of the portable electronic device, the positioning sleeve contacts watertightly an inner annular surface of the looped surrounding wall of the housing.
