Backing board having homework data storage function for students

Abstract

The invention relates to the technical field of learning tools, and especially relates to a backing board having a homework data storage function for students. Thus, the purpose of conveniently storing homework data can be realized. The backing board includes a backing board body; the top of the backing board body is movably connected to a connecting seat; the two sides on the top of the connecting seat are fixedly connected to thread bushings; the internals of the thread bushings are in threaded connection with threaded rods; and the bottom ends of the threaded rods pass through the bottom ofthe connecting seat and are in threaded connection with the top of the backing board body. Through limit devices at the internals of first placing grooves, clamping pieces can be fixed through connection boards connected to one ends of reset springs, and clamping can be performed on storage hard disks through the upper and lower clamping pieces at the internals of the first placing grooves, so that the positions of the storage hard disks can be limited; and data storage can be conveniently performed through data connectors on one ends of the storage hard disks, and the storage hard disks canbe conveniently and manually installed and dismounted through the elasticity of the reset springs, so that the purpose of convenient maintenance and replacing can be achieved.

Description

technical field [0001] The invention relates to the technical field of learning appliances, in particular to a backing board for students with the function of storing homework data. Background technique [0002] In school, teachers often require students to complete assignments such as dictation or copying on standard white paper such as A4 and B5, but it is very difficult to write neatly and beautifully on a piece of unmarked white paper. It is especially difficult for primary and middle school students to grasp the essentials, and often the whole writing is skewed or the size of the handwriting is uneven; when drawing straight lines on these white papers, although tools such as triangles can be used, students often cannot grasp the horizontal and vertical directions. , so that the graphics are crooked; in addition, the school often requires students to make tabloids. It is also a difficult task for students to divide the layout and write titles, especially when using A3 pa...
