发明名称 Handy tool pen
摘要 A handy tool pen is mainly constituted, for example, to write a brief summary and to implement a repair of hardware equipment. A hollow shaft 20 has a working end at a proximal end, where a hole axially formed through a center. A handwriting instrument of the refills is thereby stretched out from the working end, or retracted in the working end. When the handwriting instrument stretched out from the hole can write well, while the handwriting instrument retracted in the working end, which can implement a repair for hardware equipment. As well known, a spring fit around a circular cylindrical surface of the refills can urge the refills descend downward to stretch out the handwriting instrument to write, and also can urge the refills elevate upward to retract in the working end, which use for repairing office equipment or even hardware.
