Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Embodiment 1, by Figure 1-Figure 5 The utility model includes a podium 1, a fence 2 is provided on the top of the podium 1, the inner side of the fence 2 is a placement cavity, a first control button 3 is installed on the inner wall of the fence 2, a second control button 4 is installed on the inner wall of the fence 2, and a support assembly 5 is installed in the placement cavity;

[0026] The supporting assembly 5 includes a placement plate 501, two transverse chutes 502, and a circular shaft type slider 504. The placement plate 501 is located in the placement cavity. A transverse chute 502 is symmetrically opened on the inner wall of the left and right sides of the enclosure 2. The transverse chute 502 is parallel to the placement plate 501. Circular shaft type sliders 504 are symmetrically installed on both sides of the placement plate 501. The circular shaft type sliders 504 are slidably installed inside the transverse chute 502. The clamping assembly 6 is installed on the placement plate 501. The inner wall of the enclosure 2 is located in the middle of the front of the placement cavity and is equipped with a longitudinal plate 505. The inner part of the longitudinal plate 505 is opened. There is a longitudinal chute 506, and a longitudinal slider 507 is slidably installed in the longitudinal chute 506. A swivel seat 508 is installed on the side of the longitudinal slider 507 close to the placement plate 501. A swivel head 509 is installed between the placement plate 501 and the swivel seat 508. The swivel head 509 is rotatably connected to the swivel seat 508. The circular axis slider 504 is located on both sides of the placement plate 501 away from the swivel head 509. A screw 511 is rotatably installed inside the longitudinal chute 506. The screw 511 is threadedly connected to the longitudinal slider 507. The bottom end of the screw 511 is fixedly connected to the output shaft of the forward and reverse motor 510. The forward and reverse motor 510 is fixedly installed inside the podium 1. The forward and reverse motor 510 is electrically connected to the first power supply and the second power supply. The first power supply and the second power supply are arranged in parallel. The first control button 3 is arranged in series with the first power supply, and the second control button 4 is arranged in series with the second power supply. When the first control button 3 is pressed, the first power supply inputs a positive current to the forward and reverse motor 510, so that the output shaft of the forward and reverse motor 510 drives the screw 511 to rotate clockwise, driving the longitudinal slider 507 to move upward along the longitudinal slide groove 506. When the second control button 4 is pressed, the second power supply inputs a positive current to the forward and reverse motor 510. The reversing motor 510 inputs a reverse current, so that the output shaft of the forward and reverse motor 510 drives the screw 511 to rotate counterclockwise, driving the longitudinal slider 507 to move downward along the longitudinal slide groove 506. The first control button 3 and the second control button 4 are both non-self-locking switches. When the first control button 3 and the second control button 4 are released, the forward and reverse motor 510 is powered off and shut down and self-locked. When the forward and reverse motor 510 is fed with a forward current, the longitudinal slider 507 moves upward, which can push the placement plate 501 to tilt, so that the teacher will not lower his head too much when reading a book, thereby protecting the teacher's cervical spine.

[0027] The clamping assembly 6 includes a guide groove 601 symmetrically provided on the placement plate 501, a guide block 602 is slidably installed inside the guide groove 601, a top block 603 is installed on the top of the guide block 602, a clamping plate 604 is provided above the two top blocks 603, a spring 605 is installed on the top of the top block 603, the top of the spring 605 is fixedly connected to the clamping plate 604, a fixing plate 606 is symmetrically installed on the top of the placement plate 501, the fixing plate 606 is made of iron, and the two fixing plates 606 are symmetrically provided on one side of the two guide grooves 601 away from each other, a rod groove 607 is provided on the top block 603, one end of the rod groove 607 faces the fixing plate 606, a pull rod 608 is movably installed inside the rod groove 607, and the pull rod 608 is close to the fixing plate 60 6 is equipped with a magnet 609, which is adsorbed and fixed on the fixed plate 606. When the placement plate 501 is horizontal, the clamping plate 604 is pushed along the guide groove 601 to the end of the placement plate 501 close to the longitudinal plate 505, which is convenient for the teacher to work. When the placement plate 501 is tilted, the clamping plate 604 is pushed along the guide groove 601 to the end away from the longitudinal plate 505, which is convenient for supporting the book, improving the stability of the book placement, and preventing the book from falling. When the book needs to be clamped and fixed, the clamping plate 604 is pulled upward and the book is placed between the clamping plate 604 and the placement plate 501. After loosening the clamping plate 604, under the elastic force of the spring 605, the clamping plate 604 clamps the book on the placement plate 501, which is convenient for fixing the book.

[0028] Working principle: When in use, the teacher places the books needed for class on the placement board 501 and gives a lecture. When explaining the content of the book, the teacher needs to lower his head. If the head is lowered for a long time, it is easy to affect the teacher's cervical spine.

[0029] When the teacher is giving a lecture, the clamping plate 604 is pulled downward along the guide groove 601 to the side of the placement plate 501 away from the longitudinal plate 505, and then the textbook is placed on the side of the clamping plate 604 close to the longitudinal plate 505. The first power supply inputs a positive current to the forward and reverse motor 510, so that the output shaft of the forward and reverse motor 510 drives the screw 511 to rotate clockwise, driving the longitudinal slider 507 to move upward along the longitudinal slide groove 506, and then pulling the placement plate 501 close to the longitudinal plate 505 to lift up and tilt, so that the teacher does not need to lower his head too much to read the book, and the teacher is protected. When the second control button 4 is pressed, the second power supply inputs a reverse current to the forward and reverse motor 510, so that the output shaft of the forward and reverse motor 510 drives the screw 511 to rotate counterclockwise, driving the longitudinal slider 507 to move downward along the longitudinal slide 506, so that the placement plate 501 can be rotated back to the horizontal position. When the placement plate 501 is rotated to the required angle, since the first control button 3 and the second control button 4 are both non-self-locking switches, when the first control button 3 or the second control button 4 is released, the forward and reverse motor 510 is powered off and stops self-locking, so that the placement plate 501 is fixed;

[0030] When the book needs to be clamped and fixed, the clamping plate 604 is pulled upward, and the book is placed between the clamping plate 604 and the placement plate 501. Then, the clamping plate 604 is released. Under the elastic force of the spring 605, the clamping plate 604 clamps the book on the placement plate 501, making it convenient to fix the book.

[0031] When moving the position of the splint 604, first pull the pull rod 608 in the rod slot 607 on the top block 603 toward the side away from the fixed plate 606, so that the magnet 609 is separated from the fixed plate 606, and then move the splint 604. After moving to the target position, move the pull rod 608 toward the fixed plate 606, so that the magnet 609 and the fixed plate 606 are re-attracted, thereby fixing the position of the splint 604.
