[0015] Compared with the related art, the teaching reading bookshelf support device provided by the utility model has the following beneficial effects:

[0016] By providing a lifting structure and an adjustment structure, according to the height of the user, the operator sends a lifting instruction through a mobile terminal such as a mobile phone, and the single-chip microcomputer controls the second servo motor. The rotation of the power output end of the second servo motor drives the screw to rotate. When the screw rotates, it is threadedly connected with the threaded hole on the upper surface of the lifting block. Under the mutual cooperation of the slide groove on one side of the column, the lifting block is lifted and lowered. By controlling the forward and reverse rotation of the power output end of the second servo motor, the lifting and lowering of the lifting block is controlled, so that the lifting block drives the lifting rod to a suitable position, which is convenient for adjusting the height. If it is necessary to adjust the angle of the book, the operator sends a lifting instruction through a mobile terminal such as a mobile phone, and the single-chip microcomputer controls the third servo motor. The rotation of the power output end of the third servo motor drives the screw to rotate. While the screw rotates, it is threadedly connected with the threaded hole on the upper surface of the first slider, so that the first slider is lifted and lowered along the guide rail. While the first slider is lifted and lowered along the guide rail, it pushes one end of the connecting rod, so that the other end of the connecting rod pushes the second slider to move along the slide rail, thereby facilitating the adjustment of the angle of the placement plate, and then adjusting the angle of the reading book, avoiding the teacher approaching the reading bookshelf for adjustment, and increasing the convenience during use.

[0017] By providing a telescopic structure, an operator sends a telescopic instruction through a mobile terminal such as a mobile phone, and the single-chip microcomputer controls the rotation of the power output end of the first servo motor. When the power output end of the first servo motor rotates, the bevel gear is driven to rotate, and the bevel gear meshing gear plate is rotated, and the gear plate drives the threaded rod to rotate. When the threaded rod rotates, it is threadedly connected with a group of threaded holes on the upper surface of the lifting plate, so that the through holes on the upper surface of the other group of lifting plates slide on the outer surface of the sliding rod, thereby causing the lifting plate to rise and fall. When the lifting plate is lifted and lowered, the universal wheel is driven to rise and fall. The single-chip microcomputer controls the forward and reverse rotation of the power output end of the first servo motor to control the lifting and lowering of the lifting plate. When the lifting plate descends, the universal wheel contacts the ground, which facilitates the movement of the base and the movement of the position. When the lifting plate rises, the universal wheel is separated from the ground, so that the support column contacts the ground, making the base more stable, and effectively improving the stability of the reading bookshelf.

[0018] By setting a limit strip, a damping bearing, an extrusion rod, a spring and a rubber pad, the operator first places the book to be read on the upper surface of the placement plate, the operator stretches the extrusion rod, and the extrusion rod moves inside the through hole on the upper surface of the limit strip. Under the action of the rubber pad, the spring contracts to generate elastic force. After the operator unfolds the book, the limit is rotated to a blank part of the book page through the damping bearing. The operator releases the extrusion rod, and the spring is unfolded under the action of the elastic force, so that the rubber pad is close to the book page to complete the book fixation. The rubber pad prevents the extrusion rod from directly contacting the book page to cause indentation. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The working principle provided by the utility model is as follows: the operator sends a telescopic instruction through a mobile terminal such as a mobile phone, and the single-chip microcomputer 23 controls the power output end of the first servo motor 18 to rotate. When the power output end of the first servo motor 18 rotates, the bevel gear 17 is driven to rotate, and the bevel gear 17 engages the gear plate 16 to rotate, and the gear plate 16 drives the threaded rod 15 to rotate. When the threaded rod 15 rotates, it is threadedly connected with a group of threaded holes on the upper surface of the lifting plate 13, so that the through holes on the upper surface of the other group of lifting plates 13 slide on the outer surface of the sliding rod 14, thereby causing the lifting plate 11 to rise and fall. When the lifting plate 11 rises and falls, it drives the universal wheel 12 to rise and fall. The first servo motor 18 is controlled by the single-chip microcomputer 23. The forward and reverse rotation of the power output end of the motor 18 controls the lifting and lowering of the lifting plate 11. When the lifting plate 11 descends, the universal wheel 12 contacts the ground, which facilitates the movement of the base 1 and the moving position. When the lifting plate 11 rises, the universal wheel 12 is separated from the ground, so that the support column 10 contacts the ground, making the base 1 more stable. The operator first places the book to be read on the upper surface of the placement plate 9, and the operator stretches the squeezing rod 36. The squeezing rod 36 moves inside the through hole on the upper surface of the limit bar 34. Under the action of the rubber pad 38, the spring 37 contracts to generate elastic force. After the operator unfolds the book, the limit is rotated through the damping bearing 35 until the page of the book is blank. At the position, the operator releases the squeezing rod 36, and the spring 37 is expanded under the elastic force, so that the rubber pad 38 is close to the page of the book to fix the book. According to the height of the user, the operator sends a lifting command through a mobile terminal such as a mobile phone, and the single-chip computer 23 controls the second servo motor 22. The rotation of the power output end of the second servo motor 22 drives the screw 21 to rotate. When the screw 21 rotates, it is threadedly connected with the threaded hole on the upper surface of the lifting block 19. Under the mutual cooperation of the sliding groove on one side of the column 3, the lifting block 19 is lifted and lowered. By controlling the forward and reverse rotation of the power output end of the second servo motor 22, the lifting and lowering of the lifting block 19 is controlled, so that the lifting block 19 is brought The movable lifting rod 6 is lifted to a suitable position for convenient height adjustment. If the angle of the book needs to be adjusted, the operator sends a lifting command through a mobile terminal such as a mobile phone, and the single-chip computer 23 controls the third servo motor 30. The power output end of the third servo motor 30 rotates to drive the screw rod 31 to rotate. While the screw rod 31 rotates, it is threadedly connected to the threaded hole on the upper surface of the first slider 27, so that the first slider 27 is lifted and lowered along the guide rail 25.
