Abstract

A drop-resistant pen comprises a pen rod, a button device, a first linkage rod, a second linkage rod, a cartridge and a reset spring. The button device comprises a transmission part and a button part. When the button part is pressed, the button device can drive a pen point to penetrate out of a cartridge hole and protrude out of the pen rod through the first linkage rod, the second linkage rod and the cartridge. During use, a user presses the button part to allow the pen point to penetrate out of the cartridge hole and protrude out of the pen rod so as to facilitate writing. When the drop-resistant pen is not used and the button part is not pressed, the reset spring provides elastic force to reset the pen point and allow the same to be accommodated in the pen rod, and accordingly the pen point can be effectively protected by the pen rod even when the drop-resistant pen drops, and damage of the pen point is prevented.
