In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "disposed" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. The following describes an embodiment of the present invention according to its overall structure.

Referring to fig. 1-4, a touch learning card for blind persons comprises a plurality of fixing cards 1, wherein a connecting hole 2 is formed inside each fixing card 1, the inner wall of the connecting hole 2 is connected with a connecting ring 3, the top end of each fixing card 1 is provided with a groove 4, the two ends of the inner wall of each groove 4 are provided with clamping grooves 8, the inner side, located at the clamping grooves 8, of the inner wall of each groove 4 is connected with a touch card 5, the two ends of each touch card 5 are embedded with sliding grooves 6, the inner wall of each sliding groove 6 is connected with a clamping block 7, the top end of each clamping block 7 is connected with a convex block 10 penetrating to the upper portion of each touch card 5, a connecting groove 9 is formed in the position, where the touch card.

Please refer to fig. 1, the inner wall of the groove 4 is matched with the outer wall of the touch card 5, so that the touch card 5 can be conveniently clamped into the inner wall of the groove 4.

Please refer to fig. 2, the outer wall of the locking block 7 is engaged with the inner walls of the sliding groove 6 and the locking groove 8, so that the locking block 7 slides on the inner wall of the sliding groove 6 and is locked into the inner wall of the locking groove 8, and the inner wall of the sliding groove 6 is provided with a spring connected with one end of the locking block 7, so as to drive the spring to compress or reset when the locking block 7 moves.

Please refer to fig. 3, the outer wall of the protrusion 10 is engaged with the inner wall of the connecting slot 9, so that the protrusion 10 can slide on the inner wall of the connecting slot 9.

Referring to fig. 4, the fixing clip 1 is connected to another fixing clip 1 through a magnet 11, so that the fixing clips 1 can be conveniently connected to each other, thereby preventing the fixing clips from being scattered and improving the portability.

The working principle is as follows: firstly, when the touch card 5 is connected with the fixed card 1, the touch card 5 is obliquely clamped into the inner wall of the groove 4 until the touch card 5 drives the clamping block 7 at one end of the touch card to be clamped into the inner wall of the clamping groove 8, and then the clamping block 7 at the other end of the touch card 5 is clamped into the other clamping groove 8, when the touch card 5 is replaced, the convex block 10 is pressed to slide on the inner wall of the connecting groove 9, meanwhile, the convex block 10 drives one clamping block 7 to move towards the inner wall of the sliding groove 6, and the spring on the inner wall of the sliding groove 6 is compressed until the clamping block 7 completely enters the inner wall of the sliding groove 6, so that a teacher of a user can determine to replace according to whether the touch card 5 held by a learner is damaged; then, when the device is not used, the fixing card 1 and the fixing card 1 are mutually attracted through the magnet 11 inside the fixing card, so that the device is prevented from being scattered, and the portability of the device is improved.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
