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 1):
A pen structure with a glass smasher, comprising:\n a pen body having a front end formed with an aperture, wherein the pen body is provided therein, sequentially in a front-to-rear direction, with an impact groove, a tapering groove, an aligning groove, and a compression force application groove; the aperture is in communication with the impact groove, the tapering groove, the aligning groove, and the compression force application groove sequentially; the aperture has a smaller diameter than the impact groove; the tapering groove extends taperingly from a rear end of the impact groove to a front end of the aligning groove and has a wall forming a first tapering pressing surface; and the aligning groove has a smaller diameter than the impact groove and the compression force application groove; the glass smasher, mounted in the pen body at a position adjacent to the front end of the pen body and comprising:\n a smashing rod having a front section formed with a smashing cone, a middle section matching the aligning groove in diameter, and a rear section, wherein the middle section has a wall forming a second tapering pressing surface adjacent to the rear section; \n an eccentric spring mounted around a periphery of the middle section of the smashing rod and forcing an axis of the smashing rod to be offset from an axis of an impact block such that a rear end of the rear section of the smashing rod is pressed against a front end of the impact block, preventing the rear section of the smashing rod from extending into a striking groove; \n the impact block, movably positioned in the compression force application groove, wherein the front end of the impact block is able to be pressed against a wall of the compression force application groove and is concavely provided with the striking groove, the striking groove corresponds to the aligning groove, and the striking groove has a smaller diameter than the aligning groove; and \n a compression spring positioned in the compression force application groove and having two ends pressed respectively against a rear end of the impact block and a wall portion of the compression force application groove that is away from the aligning groove, in order to push the impact block toward the aligning groove and thus push the front end of the impact block against the rear end of the rear section of the smashing rod, thereby positioning the smashing rod in the impact groove, the tapering groove, and the aligning groove, with the smashing cone exposed from the front end of the pen body through the aperture, wherein when the smashing cone is pressed forcibly against a glass obstacle, the smashing rod is gradually displaced toward the compression force application groove; when the second tapering pressing surface of the wall of the middle section of the smashing rod is consequently pressed against the first tapering pressing surface, the middle section of the smashing rod begins to be guided by the aligning groove into alignment with the axis of the impact block; and as soon as the middle section of the smashing rod is in perfect alignment with the striking groove, the rear section of the smashing rod extends into the striking groove such that the impact block is forced outward by a huge elastic force stored in the compression spring and strikes a rear end of the smashing rod, thereby driving the smashing cone at a front end of the smashing rod to smash the glass obstacle forcibly; and \n a ballpoint/rollerball refill detachably provided in the pen body, wherein the ballpoint/rollerball refill has a ballpoint/rollerball tip and an ink tube, the ballpoint/rollerball tip is exposed from a rear end of the pen body, and the ink tube extends into the pen body in order for the ballpoint/rollerball refill to have a length of at least 6 cm and therefore be able to hold enough ink for use in writing or drawing for a long time, and for the pen body to have an overall length of at least 10 cm and therefore be able to be easily held by a user while the user writes or draws with the ballpoint/rollerball tip and while the user applies a force to the glass obstacle through the smashing cone at the front end of the smashing rod to smash the glass obstacle.
