[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] Referring to Figures 1 - 3 , an embodiment provided by the present invention: A recording device for vocational training, including a fixing plate 1, a motor 2 is fixedly connected to the bottom surface of the fixing plate 1, a threaded rod 3 is fixedly connected to the output end of the motor 2, a limiting block 4 is fixedly connected to the threaded rod 3 away from the output end of the motor 2, limiting rods 5 are fixedly connected to both sides of the bottom surface of the fixing plate 1, a bottom plate 7 is fixedly connected to the top surface of the fixing plate 1, an adjusting block 8 is fixedly connected to the top surface of the bottom plate 7, a connecting column 9 is fixedly connected to one side of the adjusting block 8, a worm gear 10 is fixedly connected to the middle of the connecting column 9, a sliding groove 11 is arranged on the top surface of the adjusting block 8, the sliding groove 11 is arc-shaped, a sliding rod 12 is slidably connected in the sliding groove 11, a connecting block 14 is fixedly connected to the top end of the sliding rod 12, a bolt 13 is threadedly connected to the bottom end of the sliding rod 12, a fixing seat 15 is fixedly connected to the connecting block 14, a collar 16 is fixedly connected to the middle of the bottom surface of the fixing seat 15, a transmission rod 17 is rotatably connected in the collar 16, a worm 18 is fixedly connected to the middle of the transmission rod 17, the worm 18 is meshed with the worm gear 10, and an electronic whiteboard 20 is fixedly connected to the top surface of the fixing seat 15.
[0024] A base 21 is threadedly connected to the threaded rod 3, which effectively drives the electronic whiteboard 20 to lift. The limiting rod 5 is slidably connected to the base 21 to limit the position of the fixing plate 1 and prevent the fixing plate 1 from rotating with the threaded rod 3. A handle 19 is installed on the transmission rod 17 to conveniently drive the worm 18. Two groups of adjusting blocks 8 are symmetrically arranged, and the structure is more stable during angle adjustment. Two groups of collars 16 are arranged in parallel to enhance the structural stability of the transmission rod 17. Limiting columns 6 are fixedly connected to both sides of the inner bottom surface of the base 21, and the limiting rod 5 is slidably connected in the limiting columns 6 to effectively position the limiting rod 5 and prevent the limiting rod 5 from shifting.
[0025] Working principle: When recording training information, it is necessary to adjust the electronic whiteboard 20 according to the height of the user. Start the motor 2, and the motor 2 drives the threaded rod 3 to move on the base 21 through thread movement. When the threaded rod 3 moves through thread movement, it drives the fixed plate 1 to rise. The limiting rods 5 on both sides of the bottom surface of the fixed plate 1 limit the fixed plate 1 to prevent the fixed plate 1 from shifting, completing the adjustment of the height of the electronic whiteboard 20. When it is necessary to change the angle of the electronic whiteboard 20, rotate the handle 19, and the worm 18 meshes with the worm wheel 10. The handle 19 drives the worm 18 on the transmission rod 17 to move on the worm wheel 10, thereby driving the fixed seat 15 to slide in the chute 11 on the adjusting block 8 through the slide rod 12 on the connecting block 14. Since the chute 11 is arc-shaped, the angle of the electronic whiteboard 20 can be effectively changed.
[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
