[0030] When the present embodiment is used, when the user needs to record, the positioning plug 55 is inserted into the lifting plate 52, thereby completing the installation of the writing board 56, and then the writing board 56 is used for recording. When the height of the writing board 56 needs to be adjusted, the turning handle 54 is turned, and the turning handle 54 drives the trapezoidal screw rod 53 to rotate, and the trapezoidal screw rod 53 drives the lifting plate 52 to move, thereby driving the writing board 56 to rise and fall. When the writing board 56 is no longer needed after use, the writing board 56 is inserted into the clamping seat 571, and the writing board 56 is moved upward and downward. Under the action of the sliding mouth, the clamping rod 572 will be driven to move upward, causing the clamping slider 573 to move upward to compress the clamping spring 574 until the clamping rod 572 and the clamping hole coincide. The clamping spring 574 is reset, and the clamping rod 572 is mobilized to insert into the clamping hole to fix the writing board 56, thereby storing the writing board 56. When the device is in use, it is convenient for the user to provide support when he needs to take notes, thereby facilitating recording and improving the practicality of use. In addition, the structure can conveniently store and fix the writing board 56.
