Abstract
Description
Technical Field
[0001] The utility model relates to a teaching marking structure. Background Art
[0002] When teaching Chinese characters in class, in order to help students develop a good writing plan, it is often necessary to draw a grid on the blackboard (such as Figure 3 ), the existing drawing method is to use a blackboard pen and a ruler to draw one line at a time, and the drawing efficiency is low, especially when drawing multiple groups of grids for multiple students to write on the podium, it is very troublesome, and the drawing effect is not very good (mainly because adjacent lines will deviate and not be parallel). Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Summary of the invention
[0003] The utility model provides a teaching marking structure in order to solve the problems existing in the above-mentioned prior art.
[0004] The technical solutions adopted in this utility model are:
[0005] A teaching marking structure includes a main clamp arm, a secondary clamp arm, a slider, a mounting block and a locking pin. The main clamp arm and the secondary clamp arm are both hinged on the mounting block, and a clamping gap is formed between the main clamp arm and the secondary clamp arm. The slider is slidably connected to the main clamp arm and the secondary clamp arm, the locking pin is threadedly connected to the slider, and the inner end of the locking pin abuts against the secondary clamp arm.
[0006] Furthermore, a rectangular hole is provided on the slider, and the main clamping arm and the auxiliary clamping arm are both inserted into the rectangular hole to achieve a sliding connection with the slider.
[0007] Furthermore, a guide pin is provided on the inner hole wall of the slider, and a limiting groove adapted to the guide pin is provided on the main clamping arm along the sliding direction of the slider, and the guide pin is inserted into the limiting groove.
[0008] Furthermore, a handle is provided at the end of one side of the main clamping arm away from the hinge point.
[0009] Furthermore, arc grooves arranged at equal intervals are provided on the inner wall surfaces of the main clamping arm and the auxiliary clamping arm.
[0010] Furthermore, the main clamping arm and the auxiliary clamping arm are both made of rubber.
[0011] The utility model has the following beneficial effects:
[0012] The utility model has a simple structure and can draw a plurality of mutually parallel lines at one time, and has high drawing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below in conjunction with the accompanying drawings.
[0017] like Figure 1 and Figure 2 The utility model is a teaching marking structure, comprising a main clamp arm 1, a secondary clamp arm 2, a slider 3, a mounting block 4 and a locking pin 5. The main clamp arm 1 and the secondary clamp arm 2 are both hinged on the mounting block 4, and a clamping gap 10 is formed between the main clamp arm 1 and the secondary clamp arm 2. A rectangular hole 31 is provided on the slider 3. The main clamp arm 1 and the secondary clamp arm 2 are both inserted into the rectangular hole and realize a sliding connection with the slider. The locking pin 5 is threadedly connected to the slider 3, and the inner end of the locking pin 5 abuts against the secondary clamp arm 2. A handle 11 is provided at the end of the main clamp arm 1 on one side away from the hinge point.
[0018] To ensure the sliding stability of the slider 3 , a guide pin 32 is provided on the inner hole wall of the slider 3 , and a limiting groove 12 adapted to the guide pin 32 is provided on the main clamping arm 1 along the sliding direction of the slider, and the guide pin 32 is inserted into the limiting groove 12 .
[0019] When in use, the blackboard pen is clamped between the main clamp arm 1 and the auxiliary clamp arm 2, and then the locking nail 5 is locked. In order to facilitate the rapid clamping of multiple blackboard pens with equal spacing between the main clamp arm 1 and the auxiliary clamp arm 2, arc grooves arranged at equal intervals are provided on the inner wall surfaces of the main clamp arm 1 and the auxiliary clamp arm 2. Each arc groove on the main clamp arm 1 corresponds to the arc groove on the auxiliary clamp arm 2 (for the convenience of drawing, the structure of the arc groove is omitted in the attached drawings of the utility model). When in use, the blackboard pen is placed in the arc groove, and the arc groove can also position the blackboard pen.
[0020] The main clamping arm 1 and the auxiliary clamping arm 2 are both made of rubber, which is safer to use.
[0021] In painting Figure 3 When drawing in the grid as shown, multiple blackboard pens are clamped, and then horizontal and vertical lines are drawn to improve drawing efficiency and achieve good drawing effect.
[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
