English teaching aid

Abstract

The invention discloses an English teaching aid which comprises a telescopic rod and a fixed block. The upper end of the telescopic rod is fixedly connected to the fixed block. The fixed block is configured to have a cuboid structure with a cavity formed therein. Four through holes are formed in the outer wall, located at one side of the cavity, of the fixed block. Distances between the four through holes are identical. Each through hole has one end communicating with the outside and the other end communicating with the cavity in the fixed block. A mounting plate is arranged in the cavity. Four chalk sleeves are fixedly mounted on one side surface, facing the through holes, of the mounting plate and extend to the outside through the corresponding through holes, respectively. The ends, located outside, of the chalk sleeves are opened, and a chalk is inserted in the outside opening of each chalk sleeve. The English teaching aid is simple in structure and convenient to use; the height of the fixed block can be changed by means of the telescopic rod, such that the heights of four line grids are changed; four parallel lines can be drawn up quickly by means of four chalk sleeves with identical distances therebtween, and therefore, the speed of drawing up lines and the efficiency of teaching are greatly improved.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to an English teaching aid. Background technique [0002] At present, in English teaching, teachers often have to use the teaching ruler to draw four-line grids on the blackboard, but when using the teaching ruler to draw, they can only draw one line at a time, and the distance between two adjacent lines depends on experience And visual inspection, it is difficult to grasp accurately and waste a long time, and because the length of the teaching ruler is limited, it is easy to cause the four-line grid to be non-parallel. Contents of the invention [0003] In order to solve the above problems, the present invention provides an English teaching aid which is simple in structure, easy to use, and capable of drawing four-line grids in parallel and quickly. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] An English teaching ...
