The invention discloses a telescopic torsion pen which can be rapidly operated by one single hand without need for gesture change in writing. The telescopic torsion pen comprises a penholder forepart,a pen core, a penholder posterior and a spring, wherein the body of the pen core is located in the penholder forepart and the penholder posterior, the spring wraps a portion, close to a pen tip, of the exterior of the pen core, and the pen tip in the front of the pen core can be exposed out or retracted back on the penholder forepart through axial motion of the penholder forepart and the penholder posterior so as to achieve two states of use and nonuse. The telescopic torsion pen solves the problems that a pen with a pen cap easily loses the pen cap and a traditional pressing pen is easy to operate by mistake.

The invention discloses a torsion clamping pen capable of being quickly operated by single hand without changing a gesture during writing. The torsion clamping pen comprises a pen holder front portion, a refill, a pen holder rear portion and a spring; the body of the refill is arranged in the pen holder front portion and the pen holder rear portion; and the outer part, close to a pen point, of therefill is wrapped with the spring. By adopting the torsion clamping pen disclosed by the invention, the situation that the front pen point of the refill can be exposed or retracted at the pen holderfront portion is realized through axial movement of the pen holder front portion and the pen holder rear portion so as to achieve two states of use or no use; and the problems that a pen cap of a penwith the pen cap is easy to lose and a traditional pressing pen is easy in misoperation are solved.
