Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-2, a multifunctional folder for a mathematic teacher includes a folder body 1, and further includes a fixed rod 6 fixedly disposed on one side of the folder body 1, a through hole 7 is formed at one end of the fixed rod 6, a soft rubber sleeve 8 is bonded on an inner hole wall of the through hole 7, a threaded rod 14 rotatably penetrates through a threaded hole formed at the other end of the fixed rod 6, a rotating cap 15 is fixedly sleeved on one end of the threaded rod 14, and a conical table structure is formed at the other end of the threaded rod 14.

As shown in fig. 1, the folder body 1 is composed of a first folding plate 2, a second folding plate 3 and a middle plate 4, the first folding plate 2 and the second folding plate 3 are connected to two sides of the middle plate 4, the fixing rod 6 is fixedly installed on a side surface of the first folding plate 2, and the first folding plate 2, the middle plate 4 and the second folding plate 3 are made of hard paper.

As shown in fig. 1, two U-shaped clamping bars 10 are fixedly mounted on the middle plate 4, and both the two clamping bars 10 are elastic bars.

By adopting the scheme, the clamping rod 10 is an elastic rod, and the paper files needing to be stored are clamped into the file folder by utilizing the elastic force generated when the clamping rod 10 is bent, so that the use of the traditional clamp is replaced, and the manufacturing cost is reduced.
