The two folding combination plates can be folded by the cooperation of the driving belt and the connecting belt as well as the traction block, the guide sleeve and the connecting seat, so that the two folding combination plates are gradually folded into a V shape. On the one hand, the folding process of the entire dance teaching mirror is simpler, which is convenient for storage and carrying, saves space, and is convenient for moving and using between different venues.

[0026] 3. In the present invention, by means of a positioning assembly arranged in the outer shell, when the lens is driven to be folded and unfolded by the driving mechanism, the driving shaft is used to drive the first bevel gear to rotate, thereby rotating the threaded column, driving the portal frame to move up and down, so that the positioning piece at the bottom of the portal frame can be extended and retracted when needed, which is convenient for the positioning piece to be separated from and contacted with the ground, and the positioning and fixing of the device can be achieved in conjunction with the universal wheel, thereby preventing the device from moving randomly during the teaching process, ensuring the stability and safety of use, and improving the portability of the device.

[0027] 4. In the present invention, when the lens is unfolded, the fill light strip can be turned on in conjunction with the proximity switch, which can provide good lighting for dance teaching under insufficient light conditions, allowing students to see their movements more clearly and improve teaching effects.

[0028] 5. In the present invention, the entire dance teaching mirror uses a driving mechanism as a power source and utilizes a variety of transmission methods to achieve the coordinated work of multiple functions such as folding, protection, positioning, and fill light sensing to meet the needs of portable dance teaching mirrors in different usage scenarios.

Combined with the universal wheel 6, the portability of the device is further improved and the difficulty of carrying is reduced.

[0038] In summary, the working principle of the present invention is as follows: when folding, the driver 17 is used as a power source. After starting, the driving shaft 16 is driven to rotate at the bottom of the shell 4, so that the worm 15 rotates together with the driving shaft 16, and the meshing action of the worm 15 and the worm wheel 13 is coordinated to transmit the rotational motion of the driving shaft 16 to the transmission shaft 14, so as to realize the transmission and direction conversion of power, and at this time, the installation shaft 23 is driven to rotate, and the double pulley 12 on the installation shaft 23 rotates accordingly, and the double pulley 12 is driven by the driving belt 18 and the connecting belt 11, so that the double pulleys 12 located in the same horizontal and vertical directions work together, and drive the first traction block 20, the second traction block 24 and the guide sleeve 25 to produce corresponding movements, so that the two folding combination plates 9 can be folded by the driving belt 18 and the connecting belt 11 and the traction block, the guide sleeve 25 and the connecting seat and other components, so that the two folding combination plates 9 are gradually folded into a V shape, and the two folding combination plates 9 and the lens 3 are folded into the interior of the shell 4, and the lens 3 of the dance teaching mirror is protected by the shell 4; When the lens 3 is folded, the second bevel gear 1004 at one end thereof rotates accordingly. Since the two adjacent second bevel gears 1004 are meshed with each other, when one second bevel gear 1004 rotates, it drives the other second bevel gear 1004 meshed with it to rotate, thereby rotating the threaded rod 1003, so that the movable plate 1002 screwed thereto moves laterally along the guide rod 1006, thereby driving the protection plate 1001 to move laterally in the groove 1007, so that the protection plate 1001 moves out of the groove 1007 and blocks the openings of the two V-shaped lenses 3, thereby forming a function of completely shielding and protecting the lenses 3, and preventing the lenses 3 from being damaged by external collisions and other factors; When folding and unfolding the lens 3, the rotation of the drive shaft 16 will drive the first bevel gear 805 in the positioning assembly 8 to rotate, and then drive the threaded column 802 to rotate in the F-shaped plate 801, so that the portal frame 803 screwed on the threaded column 802 moves up and down along the through opening and the guide opening 808, so that the positioning member moves with the portal frame 803. When the portal frame 803 moves downward, the positioning rod 804 is under the action of pressure and compression spring 807, and the anti-slip seat at the bottom contacts the ground to achieve positioning and fixation of the entire device; when the portal frame 803 moves upward, the anti-slip seat of the positioning rod 804 leaves the ground, the positioning is released, and the entire dance teaching mirror is transferred through the universal wheel 6.

[0039] Second implementation method: This embodiment adds the following structure on the basis of the first embodiment, so that the present application has the function of auxiliary lighting, and the specific configuration is as follows: Figure 1 and Figure 4 As shown, a fill light strip 2 is installed on one side of the inner wall around the mirror opening, and a proximity switch 21 is installed on the top of one side of the front cover 1. The proximity switch 21 is electrically connected to the fill light strip 2. The position of the proximity switch 21 is close to the position of the first traction block 20. The controller 5 is electrically connected to the fill light strip 2 and the proximity switch 21. When the first traction block 20 and other components move to the vicinity of the proximity switch 21, the proximity switch 21 senses it and transmits a signal to the controller 5. The controller 5 controls the opening or closing of the fill light strip 2 according to the signal, thereby providing auxiliary lighting when needed and providing better lighting conditions for activities such as dance teaching.

[0040] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
