## Abstract

A controllable direct liquid tool pen includes: a pen body, a fixed ring clamped on the pen body, two first through slots arranged on two sides of the fixed ring, two elastic blocks, one of which is fixedly connected to one of the two first through slots, and two second through slots arranged on the pen body into which the two elastic blocks may be inserted. The pen body is arranged with a squeezing mechanism for automatically discharging liquid. When the controllable direct liquid tool pen is used in different fields, different liquid materials can be poured into the pen body, and the liquid output volume can be controlled in real time according to actual conditions during use, ensuring the use effect, and making the adaptability of the tool pen greatly improved.

## Claims
