[0032] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0033] Please refer to Figures 1 to 7As shown, a multifunctional teaching desk includes a desktop 1, and the left and right sides of the outer bottom of the desktop 1 are fixedly connected to the table legs 2. The interior of the table legs 2 is provided with a lifting mechanism 3, and the table legs 2 include an inner shell 201 and an outer shell 202. The outer surface of the inner shell 201 is provided with a slot, and the inner shell 201 and the outer shell 202 are slidably connected to each other. The lifting mechanism 3 includes a turntable 301 arranged on the inner side of the right table leg 2, a handle 302 is fixedly connected to the outer front side of the turntable 301, a worm 303 is fixedly connected to the outer rear side of the turntable 301, the outer peripheral surface of the worm 303 is rotatably connected to a support member 304 fixed to the right table leg 2, and the outer peripheral surface of the worm 303 is meshedly connected to the worm Wheel 305, the middle part of the outer sides of the worm gear 305 is fixedly connected with a connecting rod 306, the connecting rod 306 extends to the outside of the table legs 2 on both sides and is rotatably connected to the table legs 2 on both sides, the outer peripheral surface of the connecting rod 306 and the inside of the table legs 2 on both sides are fixedly connected with a rotating disk 307, the outer peripheral surface of the rotating disk 307 is wrapped with a rope 308, one end of the rope 308 is fixedly connected to a spring 1 309, the upper and lower sides of the inner part of the inner shell 201 are respectively fixedly connected to a fixing part 1 310 and a fixing part 2 311, the end of the spring 1 309 away from the rope 308 is fixedly connected to the fixing part 1 310, and the other end of the rope 308 is fixedly connected to the fixing part 2 311. When the height of the table top 1 needs to be adjusted according to the user's height, the user first holds and rotates the handle 302, and the handle 302 drives the worm 303 to rotate through the turntable 301, and then the worm gear 305 drives the connecting rod 306 to rotate, and the rotation of the connecting rod 306 drives the rotating disk 307 inside the table leg 2 to rotate. When the rotating disk 307 rotates clockwise, one end of the rope 308 will drive the spring 1 309 to contract, and then the inner shell 201 is lowered along the notch direction through the fixing member 1 310 and the fixing member 2 311, thereby causing the table top 1 to descend. Conversely, when the rotating disk 307 rotates counterclockwise, the table top 1 is raised, so that the height of the table top 1 can be adjusted according to the user's height, meeting the usage needs of different people.

[0034] A clamping mechanism 4 is provided on the outer top of the desktop 1. A card slot 101 and a through slot 102 are provided on the outer top of the desktop 1. There are several groups of card slots 101 distributed linearly and equidistantly. A slide slot 103 is provided at the bottom of the through slot 102 and on the inner wall of the desktop 1. The clamping mechanism 4 includes a second spring 401 installed inside the through slot 102. One end of the second spring 401 is fixedly connected to the inner wall of the desktop 1. The other end of the second spring 401 is fixedly connected to a movable plate 402. The outer bottom of the movable plate 402 is fixedly connected to a slider 403. The movable plate 402 slides in the slide slot 103 through the slider 403. The outer top of the desktop 1 is also fixedly connected to a fixed plate 404. The outer right side of the fixed plate 404 is fixedly connected to a telescopic plate 405. When a book needs to be clamped, first put the book between the movable plate 402 and the fixed plate 404, then release the lock of the movable plate 402, and then the movable plate 402 will slide along the slide groove 103 under the elastic force of the spring 2 401, so as to clamp and fix the left and right sides of the book, and then pull the telescopic plate 405. The telescopic plate 405 and the rear side guard plate of the desktop 1 can fix the front and back sides of the book, so that the desktop 1 can ensure that the book is stably fixed on the top of the desktop 1 regardless of whether it is shaken left and right or front and back, avoiding the risk of the book falling from the desktop 1.

[0035] The outer bottom of the clamping mechanism 4 is provided with a locking mechanism 5, which includes a telescopic rod 501 fixedly connected to the bottom of the movable plate 402. The telescopic rod 501 is embedded with a spring 3 502. The outer peripheral surface of the extended end of the telescopic rod 501 is fixedly connected to an armrest 503. The size of the extended end of the telescopic rod 501 matches the diameter of the card slot 101. In order to avoid the user having to pull the movable plate 402 outward while placing the book between the movable plate 402 and the fixed plate 404, which causes operational difficulties, the user only needs to pull the movable plate 402 outward and move the armrest 503 upward. After the movable plate 402 reaches the designated position, the armrest 503 is released. The telescopic end of the telescopic rod 501 will enter the card slot 101 due to the elastic force of the spring 2 401, thereby fixing the movable plate 402. After the book is placed, the armrest 503 is moved upward to clamp the movable plate 402 stably and effectively.

[0036] The working principle and use process of the device are as follows: first, the user holds and rotates the handle 302, the handle 302 drives the worm 303 to rotate through the rotating disc 301, and then the worm wheel 305 drives the connecting rod 306 to rotate, the rotation of the connecting rod 306 drives the rotating disc 307 inside the table leg 2 to rotate, when the rotating disc 307 rotates clockwise, one end of the rope 308 drives the spring I 309 to contract, and then the inner shell 201 is lowered along the slot direction through the fixing part I 310 and the fixing part II 311, and then the table top 1 is lowered, and vice versa, when the rotating disc 307 rotates counterclockwise, the table top 1 is raised, so that the height of the table top 1 can be adjusted according to the height of the user, and the use requirements of different groups of people are met.

[0037] Secondly, when the book needs to be clamped, first, the book is placed between the movable plate 402 and the fixed plate 404, then the movable plate 402 is unlocked, and then the movable plate 402 slides along the sliding groove 103 direction through the elastic force of the spring II 401, so that the left and right sides of the book are clamped and fixed, then the telescopic plate 405 is pulled, and the telescopic plate 405 and the rear side guard plate of the table top 1 can fix the front and back sides of the book, so that the table top 1 is ensured to be stably fixed on the top of the table top 1, and the risk of the book falling from the table top 1 is avoided.

[0038] Finally, in order to avoid the situation that the user needs to pull the movable plate 402 outward and place the book between the movable plate 402 and the fixed plate 404 at the same time, causing operation difficulty, at this time, only the movable plate 402 is pulled outward and the handrail 503 is pulled upward, after the movable plate 402 reaches the specified position, the handrail 503 is loosened, the telescopic end of the telescopic rod 501 enters the clamping groove 101 due to the elastic force of the spring II 401, and then the movable plate 402 is fixed, and after the book is placed, the handrail 503 is pulled upward, the movable plate 402 can stably and effectively clamp the book.
