Problems solved by technology
[0005] Aiming at the deficiencies in the prior art, the present invention provides a multi-functional English teaching aid, which solves the problem that most of the existing English teaching aid blackboards on the market have some simple functions when in use, and the shape of the blackboard itself when in use Larger, it takes up more space when it is summarized, so it cannot be folded flexibly to reduce its size, and it is very inconvenient to use. At the same time, the English letters or patterns for teaching will be adsorbed when they are fixed and connected to the blackboard. The phenomenon of unstable falling will have certain limitations in teaching. The books that will be used in the end cannot be summarized inside the blackboard. Troublesome problems when taking and applying

A multifunctional English teaching aid disclosed by the present invention comprises a first blackboard teaching aid, a second blackboard teaching aid and a supporting cylinder, the exterior of the supporting cylinder is fixedly connected with a rotating shaft, the rotating shaft is in an average annual division form, and the exterior of the rotating shaft is connected with the second blackboard teaching aid in a welding mode. The outer side of the supporting cylinder is connected with the first blackboard teaching aid in a welded mode. The rotating shafts are distributed outside the supporting cylinder, the first blackboard teaching aid and the second blackboard teaching aid are arranged during use, the second blackboard teaching aid is connected to the outer portions of the rotating shafts, the second blackboard teaching aid can be folded and rotated through the rotating shafts, the second blackboard teaching aid is attached to the first blackboard clamp, and therefore a certain space can be saved during storage; the first blackboard teaching aid and the second blackboard teaching aid can be fixed by inserting the fixing blocks into the fixing grooves, the phenomena of shaking and instability cannot occur during use, and the blackboard teaching aid is convenient to use.
Description
technical field [0001] The invention relates to the technical field of English teaching aids, in particular to a multifunctional English teaching aid. Background technique [0002] Before the invention of writing, people discovered that charcoal could be used for painting. Some ancient murals can be found in some ancient caves in Europe. The rock walls with these murals can be called blackboards in the traditional sense. [0003] Most of the English teaching aid blackboards on the market have some simple functions when they are used. The shape of the blackboard itself is relatively large when it is used, and it takes up more space when it is summarized, so it cannot be folded flexibly to reduce The size is very inconvenient to use. At the same time, when the English letters or patterns for teaching are fixed and connected to the blackboard through adsorption, the phenomenon of adsorption instability and falling will occur. There will be certain limitations in teaching. Final...
