Abstract:
A pen structure with a glass smasher has the glass smasher mounted at the front end of a pen. When a user holds the pen and presses the front end (i.e., the smashing cone) of the smashing rod of the glass smasher forcibly against a glass obstacle, an impact block will strike the rear section of the smashing rod vigorously such that the smashing cone is instantly driven to smash the glass obstacle. A ballpoint/rollerball refill is detachably provided in the pen and is at least 6 cm long in order to contain enough ink. The overall length of the pen is at least 10 cm so that the pen can be easily held while the user writes or draws with the ballpoint/rollerball tip and while the user applies a force to a glass obstacle through the front end of the smashing rod to smash the glass obstacle.

Claim (Index 18):
The pen structure of  claim 17 , wherein the pen body further comprises an ink tube positioning member, the ink tube positioning member has a rear end connected to the front end of the connecting barrel section and has a front end extending into the compression force application groove, the ink tube positioning member is provided therein with an ink tube positioning space in which to position a portion of the ink tube that is away from the ballpoint/rollerball tip, thereby keeping the ink tube from falling off; the front end of the rear barrel section is movably connected to the rear end of the ink tube positioning member or the rear end of the connecting barrel section; the user, when desiring to write or draw with the ballpoint/rollerball tip, only has to turn the rear barrel section in a direction with fingers, and the rear barrel section will be displaced toward the connecting barrel section and thereby drive the ballpoint/rollerball tip of the ballpoint/rollerball refill out of the pen opening so that the ballpoint/rollerball tip is exposed from the rear end of the rear barrel section and ready for use in writing or drawing; and when the ballpoint/rollerball tip is not to be used, the user only has to turn the rear barrel section in an opposite direction with the fingers, and the rear barrel section will be displaced away from the connecting barrel section and thereby retract the ballpoint/rollerball tip of the ballpoint/rollerball refill into the pen opening so that the ballpoint/rollerball tip is stored and hidden in the second receiving space of the rear barrel section.
