[0006] As a preferred technical solution of the utility model, two downward extension blocks are provided at the bottom of the touch panel, and the two extension blocks are fitted with both sides of the outer wall of the connecting rod, and the connecting rod is rotatably connected to the extension blocks at the bottom of the touch panel.

[0007] As a preferred technical solution of the utility model, the threaded rod is located inside the sliding groove, and the sliding groove passes through the sliding block, the sliding block is threadedly connected to the threaded rod, and the outer wall of the sliding block fits with the inner wall of the sliding groove.

[0008] As a preferred technical solution of the present invention, a circular groove is provided on the inner wall of the earphone compartment, and the circular groove on the inner wall of the earphone compartment penetrates the inner wall of the bottom plate close to the fixing column.

[0009] As a preferred technical solution of the utility model, the top of the pressure rod penetrates the outer wall of the bottom plate, and a circular groove is provided at the bottom of the pressure rod, and the diameter of the circular groove at the bottom of the pressure rod is the same as the diameter of the top of the fixing column.

[0010] As a preferred technical solution of the utility model, the ratchet block is at the same height as the ratchet wheel, and the ratchet block is meshed with the ratchet surface of the ratchet wheel.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The listening aid trainer for English majors rotates the threaded rod so that the threaded rod drives the sliding block to move inside the sliding groove through the thread. At this time, the movement of the sliding groove drives the bottom end of the connecting rod to move, and the connecting rod is rotated inside the sliding groove. The bottom end of the connecting rod moves, which drives the top end of the connecting rod to move, and drives the touch panel to move, so that the touch panel drives the fixed rod to move inside the movable groove, and then the end of the touch panel close to the bottom extension block moves upward, so that the touch panel is tilted.

[0013] 2. This listening aid trainer for English majors pulls the earphone outward, causing the winding reel to rotate and the ratchet block to move outside the ratchet wheel. When the pulling force of the winding reel disappears, the resilience of the clockwork spring will pull the winding reel back. At this time, the ratchet block and the ratchet wheel are engaged to offset the pullback of the clockwork spring. After the earphone is used, the pressure rod is pressed downward from the top of the bottom plate to drive the ratchet wheel to move, causing the tension spring to contract. At this time, the fixed column enters the circular groove at the bottom of the pressure rod. At this time, the ratchet wheel is disengaged from the ratchet block, and the winding reel is reset by the recovery of the clockwork spring, so that the winding reel rewinds the earphone and the earphone head enters the interior of the earphone compartment. At this time, the closing door is closed to complete the storage of the earphone. BRIEF DESCRIPTION OF THE DRAWINGS

In the above structure, there are two movable grooves 3, and the two movable grooves 3 are symmetrically distributed on both sides of the inner wall of the base plate 1.

[0023] In a preferred embodiment, two downward extension blocks are provided at the bottom of the touch pad 5, and the two extension blocks are fitted with both sides of the outer wall of the connecting rod 11, and the connecting rod 11 is rotatably connected to the extension blocks at the bottom of the touch pad 5. In the above structure, by pulling the sliding block 10, the sliding block 10 drives the bottom end of the connecting rod 11 to move, so that the bottom end of the connecting rod 11 rotates on the inner wall of the sliding block 10, so that the other end of the connecting rod 11 drives the extension block at the bottom of the touch pad 5 to move upward, and then drives the side of the touch pad 5 close to the bottom extension block to move upward.

[0024] In a preferred embodiment, the threaded rod 8 is located inside the sliding groove 9, and the sliding groove 9 passes through the sliding block 10, the sliding block 10 is threadedly connected to the threaded rod 8, and the outer wall of the sliding block 10 fits with the inner wall of the sliding groove 9. In the above structure, by rotating the threaded rod 8, the threaded rod 8 drives the sliding block 10 to move inside the sliding groove 9 through the thread. When the sliding block 10 moves inside the sliding groove 9, the outer wall of the sliding block 10 fits with the inner wall of the sliding groove 9, so that the sliding block 10 is limited by the sliding groove 9, thereby preventing the sliding block 10 from being offset due to the rotational force of the threaded rod 8.

[0025] In a preferred embodiment, a circular groove is provided on the inner wall of the earphone compartment 6, and the circular groove on the inner wall of the earphone compartment 6 penetrates the inner wall of the bottom plate 1 close to the fixed column 12. In the above structure, the earphone cable is wound on the outer wall of the winding drum 14, and the earphone is inserted through the circular groove on the inner wall of the earphone compartment 6, so that the earphone enters the interior of the earphone compartment 6 through the circular groove on the inner wall of the earphone compartment 6.

The diameter of the circular groove at the bottom of the pressure rod 13 is the same as the diameter of the top of the fixed column 12. In the above structure, by pressing the pressure rod 13 downward from the top of the base plate 1, the bottom of the pressure rod 13 drives the ratchet 15 to move downward, thereby driving the tension spring 16 to contract. At this time, the fixed column 12 enters the circular groove at the bottom of the pressure rod 13.

[0027] In a preferred embodiment, the ratchet block 17 has the same height as the ratchet wheel 15, and the ratchet block 17 meshes with the ratchet surface of the ratchet wheel 15. In the above structure, the earphones are pulled outward to drive the winding reel 14 to rotate, so that the ratchet block 17 moves in a circle outside the ratchet wheel 15. When the pulling force of the winding reel 14 disappears, the rebound force of the clockwork spring 18 will pull the winding reel 14 back. At this time, the ratchet block 17 is engaged with the ratchet wheel 15, so that the winding reel 14 is fixed.

[0028] Working principle: when in use, place the bottom plate 1 flat on the desktop. At this time, the touchpad 5 needs to be tilted so that the touchpad 5 can be viewed more directly. By rotating the threaded rod 8, the threaded rod 8 drives the sliding block 10 to move inside the sliding groove 9 through the thread. When the sliding block 10 moves, the sliding block 10 drives the bottom end of the connecting rod 11 to move, so that the bottom end of the connecting rod 11 rotates on the inner wall of the sliding block 10, so that the other end of the connecting rod 11 drives the extending block at the bottom of the touchpad 5 to move upward, so that the touchpad 5 moves close to one end of the fixed rod 4, and then drives the fixed rod 4 to move on the inner wall of the movable groove 3, so that the side of the touchpad 5 close to the bottom extending block moves upward, so that the touchpad 5 is tilted. At this time, start the device, so that the touchpad 5 lights up, and the speaker 2 plays English listening. When headphones need to be used in a public area, pull the closed door 7 to make the headphones inside the headphone compartment 6 leak out, and the headphones are put into the earphone compartment. The cable drum 14 is reset by the restoring force of the spring 18, so that the cable drum 14 rewinds the earphones, so that the earphone heads enter the interior of the earphone compartment 6, and the closing door 7 is closed to complete the storage of the earphones.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
