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 12):
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 and a compression force application groove; the aperture is in communication with the impact groove and the compression force application groove sequentially; the aperture has a smaller diameter than the impact groove and the compression force application groove; the glass smasher, mounted at the front end of the pen body and comprising:\n a smashing rod having a front section with a front end formed with a smashing cone; \n a guide spring mounted around a periphery of the smashing rod at a position adjacent to a middle section and a rear section of the smashing rod, wherein the guide spring has a front end pressed against a portion of the smashing rod that is adjacent to the front section of the smashing rod, thereby forcing an axis of the smashing rod to be offset from an axis of the compression force application groove and pushing the smashing rod outward of the aperture such that the smashing cone of the front section of the smashing rod is driven through the aperture and exposed from the front end of the pen body; \n a guide block movably positioned in the compression force application groove, wherein the guide block has a front-end wall able to be pressed at least against a rear end of the guide spring, the front-end wall of the guide block is concavely provided with a guide groove, the guide groove matches the middle section and the rear section of the smashing rod in diameter so that a rear end of the smashing rod is able to extend through the guide groove, and the front-end wall or a rear-end wall of the guide block forms a curved guide surface; \n an offset striking block movably positioned in the compression force application groove, wherein the offset striking block has a front-end side pressed against the rear-end wall of the guide block and concavely provided with a striking groove corresponding to the guide groove such that, once extending through the guide groove, the rear end of the smashing rod is pressed against the front-end side of the offset striking block to prevent the rear section of the smashing rod from extending into the striking groove; and the front-end side or a rear-end side of the offset striking block also forms a curved guide surface; and \n a compression spring positioned in the compression force application groove, wherein the compression spring has a front end pressed against the rear-end side of the offset striking block and has a rear end pressed against a wall of the compression force application groove, in order to push the offset striking block toward the impact groove and apply a huge elastic force to the offset striking block, and while the compression spring is being compressed, the curved guide surfaces fine-tune the compression spring and the offset striking block in angle and position, in order for the striking groove in the offset striking block to correspond to the guide groove, and for the rear end of the smashing rod to extend into the striking groove immediately after passing through the guide groove; 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 a glass obstacle through the smashing cone at a front end of the smashing rod to smash the glass obstacle.
