Wireless touch pen

The invention discloses a wireless touch pen. The pen comprises a pen head, a pen shell, and a circuit module and a signal transmission module which are arranged in the pen shell, wherein the circuit module is connected with the pen head and has a signal amplification function; the signal transmission module has the function of increasing a wireless signal receiving angle; and the pen head is exposed from the pen shell. Through the mode, the pen has a simple structure and can receive wireless transmission signals such as infrared transmission signals and send communication protocol signals, so that wireless communication and remote control between the pen and display terminal equipment with a touch writing function are realized, wireless signals such as infrared signals at various angles are easily received, and the induction sensitivity of the pen and a touch screen is obviously improved.
