The invention discloses an ink bottle with a function of preventing ink from shaking and scattering and ink for writing brush calligraphy. The ink bottle comprises a bottle body, an opening pipe is embedded in the top wall of the bottle body, the opening pipe is suspended in an inner cavity of the bottle body, a sliding cavity is formed in the bottom of the inner cavity wall of the opening pipe, a tightening cavity is embedded in the top wall of the sliding cavity, a lifting cylinder matched with the sliding cavity is slidably connected into the tightening cavity, a plurality of telescopic rods are evenly arranged at the top end of the lifting cylinder, the top ends of the telescopic rods are fixedly connected to the top wall of an inner cavity of the tightening cavity, pre-tightening springs sleeve the outer sides of the telescopic rods, one side end of the lifting cylinder is connected with a drainage hole in a penetrating mode, and a bottle plug matched with the bottle body is arranged at the top end of the opening pipe. When ink is not taken out, the lifting cylinder is retracted into the tightening cavity through mutual cooperation of the pre-tightening springs and the telescopic rods, the drainage hole can be sealed through the opening pipe, the opening pipe can be sealed through the lifting cylinder, the bottle plug can be effectively prevented from being collided to spill ink when opened, the ink containing safety of the bottle body can be guaranteed to the maximum extent, and the ink containing convenience of the whole device can be greatly improved.
