Teaching device suitable for primary school Chinese teaching

Abstract

The invention discloses a teaching device suitable for primary school Chinese teaching. The teaching device suitable for primary school Chinese teaching comprises a teaching device main body, a thirdsliding groove and an auxiliary mechanism, wherein first sliding grooves are embedded in the surface of the teaching device main body, first sliding blocks are movably connected to the interiors of the first sliding grooves, and a linkage rod is fixedly connected to the middles of the first sliding blocks. Connecting rods are fixedly connected to the inner sides of the top and the bottom of the linkage rod, a mounting groove is fixedly connected to the inner sides of the connecting rods, and the mounting groove, a wiping strip, a mounting plate, fixing buttons, connecting columns and the linkage rod jointly form a wiping mechanism. When a blackboard needs to be wiped, the linkage rod is pulled to drive the wiping strip to move on the blackboard through the first sliding grooves and first sliding blocks, the wiping strip on the inner side of the mounting groove makes contact with the blackboard, and the blackboard is wiped in the moving process of the wiping strip. When the wiping stripis used for a long time and is poor in wiping effect, the wiping strip in the mounting groove is taken out to be replaced, the wiping effect is guaranteed, and the amount of chalk dust inhaled by teachers can be reduced.
