The invention discloses an English teaching board easy to adjust. The English teaching board easy to adjust comprises a teaching board body. The surface of the teaching board body is engraved with English letters and a three-line grid. A connecting block is fixedly connected to the middle of the bottom of the teaching board body, and fixed rods are fixedly connected to the two sides of the outer wall of the connecting block. The upper ends of the fixed rods are fixedly connected to the lower end of the teaching board body, an inner cylinder is arranged on the lower side of the connecting block, and the lower end of the connecting block is rotatably connected with the upper end of the inner cylinder by an overturning mechanism. A limiting block is fixedly connected to the lower end of the inner cylinder, a threaded hole penetrating up and down is formed in the limiting block, a threaded rod is connected into the threaded hole in a threaded mode, and an outer cylinder is slidably arranged on the outer side of the inner cylinder, and a base is fixedly connected to the lower end of the outer cylinder. The English teaching board easy to adjust is provided with the English letters and three-line grid and can be rotated left and right. The front-and-back rotation and the up-and-down rotation solve the problems that a teaching board of the market does not have the convenience of learning English, and the height adjustment of the teaching board and the angle adjustment of the teaching board are not convenient.
