[0022] Example 1:

[0023] like Figs. 1-6 As shown, a blackboard marking device for English teaching includes a blackboard body 1. A support frame 2 is provided on the left side of the front of the blackboard body 1. A limit block 3 is slidably sleeved on the outer wall of the support frame 2. A handle 32 is fixedly installed on the front of the limit block 3. Iron strips 21 are fixedly embedded on both sides of the support frame 2. Magnetic sheets 31 are fixedly embedded on both sides of the inner wall of the limit block 3. The outer wall of the magnetic sheet 31 is magnetically connected to one side of the iron strip 21. A marking fixing plate 4 is fixedly installed on the right side of the limit block 3. Four mounting cylinders 41 are evenly distributed inside the marking fixing plate 4 and connected by internal threads. Inside the marking plate 4, four mounting cylinders 41 each contain a piece of chalk 43. There are four pieces of chalk 43 in total. The rear end of the chalk 43 overlaps the front of the blackboard body 1. The top and bottom of the blackboard body 1 are fixedly connected to a limiting frame 6. The top and bottom of the inner wall of the support frame 2 are fixedly connected to a slider 5. The outer wall of the slider 5 is slidably connected to the inside of the limiting frame 6. A small blackboard eraser 48 is fixedly installed on the upper back of the marking plate 4. The back of the small blackboard eraser 48 overlaps the front of the blackboard body 1. The small blackboard eraser 48 is located above the chalk 43.

[0024] In the embodiment, the limiting block 3 is vertically moved, and the marking fixed plate 4, the mounting cylinder 41, the chalk 43 and the small blackboard eraser 48 are moved by the limiting block 3, so that the height of the four chalks 43 is adjusted, and the small blackboard eraser 48 is arranged, so that the marking line left by the chalk 43 on the blackboard body 1 is wiped. The magnetic sheet 31 in the limiting block 3 is magnetically adsorbed on the iron strip 21 on the outer wall of the support frame 2 at any position, so that the limiting block 3, the marking fixed plate 4, the mounting cylinder 41 and the chalk 43 are positioned, the height of the chalk 43 during marking is adjusted, the support frame 2 is horizontally moved, and the support frame 2 is horizontally guided by the cooperation of the sliding block 5 and the limiting frame 6. The support frame 2 moves while driving the limiting block 3, the marking fixed plate 4, the four mounting cylinders 41 and the four chalks 43 to move horizontally, so that the four chalks 43 are used to quickly mark four auxiliary lines for English writing on the blackboard body 1.

[0025] Embodiment two:

[0026] As shown in Figs. 1-6 , the front end of the inner wall of the mounting cylinder 41 is fixedly connected with the spring 45, the initial length of the spring 45 is in a compressed state, the rear end of the spring 45 is fixedly connected with the limiting plate 44, the outer wall of the limiting plate 44 is movably sleeved in the inner wall of the mounting cylinder 41, the front end of the chalk 43 is overlapped on the back of the limiting plate 44, the top and the bottom of the inner wall of the mounting cylinder 41 are provided with the guide groove 47, the top and the bottom of the limiting plate 44 are fixedly connected with the guide block 46, the outer wall of the guide block 46 is slidably connected in the inner wall of the guide groove 47, the front end of the mounting cylinder 41 is fixedly connected with the knob 42, and the back of the knob 42 is overlapped on the front of the marking fixed plate 4.

[0027] In the embodiment, the inner wall of the marking fixed plate 4 is provided with an internal thread, and the outer wall of the mounting cylinder 41 is provided with an external thread matched with the internal thread of the inner wall of the marking fixed plate 4. The mounting cylinder 41 is moved out of the inner wall of the marking fixed plate 4 by rotating the knob 42 and the mounting cylinder 41, so that the chalk 43 in the mounting cylinder 41 can be replaced. After replacement, the mounting cylinder 41 is screwed in the inner wall of the marking fixed plate 4 in the same way, and the rear end of the chalk 43 is overlapped on the front of the blackboard body 1. When the mounting cylinder 41 moves in the inner wall of the marking fixed plate 4, the rear end of the chalk 43 is pressed against the blackboard body 1, the front end of the chalk 43 presses the limiting plate 44, the limiting plate 44 drives the guide block 46 to slide in the guide groove 47, the front of the limiting plate 44 is pressed by the compression spring 45, and the spring 45 is in a compressed state. When the chalk 43 is used for marking, the rear end of the chalk 43 is gradually worn and shortened. At this time, the spring 45 exerts a rebound force on the limiting plate 44 and the chalk 43, so as to push the chalk 43 to move, and the rear end of the chalk 43 can be attached to the blackboard to mark.

[0028] In summary, as shown in Figs. 1-6As shown, the chalk line marker for English teaching is used, the teacher can drive the limiting block 3 to move vertically on the outer wall of the support frame 2 through the handle 32, the limiting block 3 drives the chalk line fixing plate 4, the mounting cylinder 41, the chalk 43 and the small chalk eraser 48 to move, the height of the four chalks 43 is adjusted, and the chalk line left on the blackboard by the vertical movement of the chalk 43 is wiped off by the small chalk eraser 48; after moving, the magnetic sheet 31 on the inner wall of the limiting block 3 is adsorbed on the iron bar 21 on the two sides of the support frame 2, so that the limiting block 3 is positioned, at this time, the teacher can move the support frame 2 horizontally, the support frame 2 drives the sliding block 5 to slide horizontally in the limiting frame 6, and the support frame 2 drives the limiting block 3, the chalk line fixing plate 4, the four mounting cylinders 41 and the four chalks 43 to move horizontally, and four chalks 43 are used to quickly draw four auxiliary lines for English writing on the blackboard.
