Detailed ways

The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

1 to 4, the English teaching vocabulary display device includes a frame 1, and a writing board 2 is arranged in the frame 1. It is characterized in that a guide rod 3 is fixed on the upper part of the frame 1, and the guide rod 3 is slidably connected. There is a sliding block 4, the lower part of the sliding block 4 is fixed with a shielding plate 5 located on the front side of the writing board 2, and a mounting bar 6 is fixed in the middle of the side of the shielding plate 5 facing the writing board 2, and the upper and lower ends of the mounting bar 6 are slidably connected There is a transverse guide rod 7, and the guide rod 7 is slidably connected to the mounting bar 6 through the mounting bar 6, and a clamping bar 8 is fixed between the same ends of the two said guiding bars 7. A shielding cloth is arranged between, one side of the frame 1 is provided with a rotating shaft 9, both ends of the rotating shaft 9 are fixedly connected with the frame 1 through the mounting seat, and a plurality of marking components are arranged on the rotating shaft 9 at intervals, and the marking components include The reel 10 and the card seat 11 are rotatably connected with the rotating shaft 9. The reel 10 is wound with a marking line, the free end of the marking line is fixed with a clamping block, and the card seat 11 is fixed on the side of the frame 1 away from the marking assembly. The seat 11 is provided with a card slot 12 . The writing pad 2 is used for writing, and the shielding plate 5 is used to shield the content on the writing pad 2 . The shielding plate 5 can slide along the guide rod 3 to shield different positions of the writing pad 2 . By stretching the clamping bar 8, the length of the shielding plate 5 extending out of the shielding plate 5 can be adjusted, and then the range of shielding and covering the writing plate 2 can be adjusted. range. When marking is required, one end of the marking line is fixed on the reel 10, and the other end of the marking line passes through the card slot 12 of the card seat 11, and then the card block cooperates with the card slot 12 so that one end of the marking line is fixed on the card.
