[0026] Embodiment: a dance class uses leg flexibility training device, such as Figures 1-6As shown, it comprises base 1, moving rod 2, caster 3, handle 4, sleeve I 5, telescopic rod I 6, leg pad 7, clamping ball 801 and spring I 802, one side of the lower part of base 1 is slidably connected with moving rod 2, the bottom of moving rod 2 is rotatably connected with caster 3, the top of moving rod 2 is connected with handle 4 by screwing, the middle of moving rod 2 is rotatably connected with sleeve I 5 on both sides, the middle of moving rod 2 is provided with a limiting piece, so that the two sleeves I 5 can only rotate on one side of moving rod 2, the two sleeves I 5 rotate the same number of degrees at the same time, the inside of both sleeves I 5 is slidably connected with telescopic rod I 6, the end of both telescopic rod I 6 away from each other is rotatably connected with leg pad 7, both sides of telescopic rod I 6 can be supported, a plurality of clamping holes 8 are formed on both sides of sleeve I 5 and telescopic rod I 6, clamping ball 801 is slidably connected in clamping hole 8 of telescopic rod I 6, spring I 802 is connected between the inner wall of clamping hole 8 of telescopic rod I 6 and clamping ball 801, and the clamping hole 8 of sleeve I 5 is matched with clamping ball 801.

[0027] As shown in Figure 1 , Figure 2 and Figure 4 , it further comprises sleeve II 9 and telescopic rod II 10, the bottom of one side of telescopic rod I 6 is rotatably connected with sleeve II 9, the inside of sleeve II 9 is slidably connected with telescopic rod II 10, and telescopic rod II 10 is rotatably connected with the bottom of the other side of telescopic rod I 6, when the sleeves I 5 on both sides of moving rod 2 drive telescopic rod I 6 and leg pad 7 to move in different directions at the same time, sleeve II 9 and telescopic rod II 10 expand or contract accordingly.

[0028] As shown in Figure 1 , Figure 2 and Figure 6 , it further comprises limiting rod 11, limiting strip 111, fixed disc 12, sleeve III 121, contact plate 122, telescopic rod III 13, spring II 14, pull ring 15 and back pad 16, limiting rod 11 is connected in the middle of base 1 by welding, limiting rod 11 is located directly above moving rod 2, a plurality of symmetrical limiting strips 111 are arranged on the bottom of limiting rod 11, fixed disc 12 is connected in the middle of moving rod 2 by screwing, sleeve III 121 is slidably connected on fixed disc 12, contact plate 122 is connected at the lower end of sleeve III 121 by welding, the top of contact plate 122 is in contact with limiting strip 111, telescopic rod III 13 is slidably connected in the inside of sleeve III 121, the top of telescopic rod III 13 is inclined, spring II 14 is connected between telescopic rod III 13 and sleeve III 121, and spring II 14 is wound outside telescopic rod III 13, pull ring 15 is slidably connected on handle 4, the bottom of pull ring 15 is in sliding contact with the inclined part at the top of telescopic rod III 13, back pad 16 is arranged on one side of the top of base 1, and base 1 and back pad 16 form a seat conforming to ergonomics.

[0029] The training device is suitable for dancers of different heights and body shapes by adjusting the distance of the leg pads 7. First, the clamping balls 801 outside the clamping holes 8 on both sides of the sleeve I 5 and the telescopic rod I 6 are pushed inward, and the spring I 802 is deformed and compressed. Then, the telescopic rod I 6 is slid to the appropriate position, and the clamping holes 8 on both sides of the sleeve I 5 and the telescopic rod I 6 are aligned. The clamping balls 801 slide outward under the action of the spring I 802 and can be clamped in different positions of the clamping holes 8, thereby fixing the length of the telescopic rod I 6, i.e., the adjustment is completed.

[0030] When the dancer needs to stretch the flexibility of the inner side of the legs back and forth during the dance class, first, the training device is placed on a relatively open horizontal ground. The dancer first sits on the base 1, then lifts both legs and places them on the leg pads 7 on both sides. After sitting down, the dancer pulls the pull ring 15 towards himself. When the lower part of the pull ring 15 touches the inclined surface of the telescopic rod III 13, it will drive the telescopic rod III 13 to move downward along the sleeve III 121. The spring II 14 is deformed and compressed, and then the spring II 14 will drive the sleeve III 121 to slide downward on the fixed disc 12 by the self-expanding force. The contact plate 122 of the sleeve III 121 is separated from the limiting strip 111 on the limiting rod 11. Continue to pull the pull ring 15 to move the handle 4, and pull the pull ring 15 to the end of the handle 4 closest to oneself. Then, through the casters 3, the handle 4 and the moving rod 2 are slid towards oneself, and the sleeves I 5 on both sides will drive the telescopic rods I 6 and the leg pads 7 to move away from each other. The sleeves II 9 and the telescopic rods II 10 are stretched to provide additional leg support, so that the dancer's inner legs are slowly stretched. Continue to pull slowly towards oneself until the dancer's degree is appropriate, and then push the pull ring 15 away from oneself. The pull ring 15 touches the inclined surface of the telescopic rod III 13 away from oneself, and pushes the telescopic rod III 13 downward. The moving rod 2 slides away from oneself, and then the sleeves I 5 on both sides drive the telescopic rods I 6 and the leg pads 7 to move towards each other. The sleeves II 9 and the telescopic rods II 10 are contracted to provide additional leg limiting, so that the dancer's inner legs are relaxed. That is, one round is completed. If you need to do several sets of flexibility training of the inner side of the legs back and forth, you can do it repeatedly. This changes the previous flexibility training method of the inner side of the legs during the dance class, and achieves the effect of flexibility training of the inner side of the legs without bending down. The training device is also suitable for beginners, reducing the risk of injury due to stretching.

[0031] When the dancer needs to keep the flexibility training of the inner leg stretching in the dance class, the inner thigh stretching is performed as the above steps, the dancer slowly pulls the pull ring 15 to the direction close to himself until reaching the suitable degree of the dancer, then releases the pull ring 15, the pull ring 15 slides to the middle of the top surface inclined surface of the telescopic rod III 13, the spring II 14 deforms and rebounds, the sleeve III 121 and the telescopic rod III 13 are reset, the contact plate 122 of the sleeve III 121 contacts the limiting strip 111 of the limiting rod 11, so that the sleeve III 121 and the limiting rod 11 are clamped, that is, the inner leg stretching training is kept, the dancer can sit straight or lean on the back pad 16, so as to achieve the effect of reducing the waist pressure, after stretching for a suitable time, the pull ring 15 is pushed away from the dancer, so that the pull ring 15 contacts the surface away from the dancer of the top surface inclined surface of the telescopic rod III 13, the top surface inclined surface of the telescopic rod III 13 is pushed down as above, the moving rod 2 slides away from the surface of the dancer, then the sleeves I 5 on both sides drive the telescopic rods I 6 and the leg pads 7 to move to the side close to each other, so that the inner legs are relaxed, and the initial state is restored.

[0032] The above embodiments are only the preferred embodiments of the present application, and are not used to limit the scope of the present application, so that equivalent changes made according to the content of the present application claims should be included in the scope of the present application claims.
