[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The following describes the specific embodiments of the present invention in conjunction with the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, a flexibility training device includes a fixed plate 1, side plates 2, handrails 3 and a limit plate 4. Two side plates 2 are symmetrically rotatably installed on one end of the top of the fixed plate 1. The end of the side plate 2 away from the bottom of the side plate 2 is equipped with a roller 5. The lowest point of the roller 5 is flush with the bottom of the fixed plate 1. The roller 5 increases the stability of the side plate 2 and reduces the friction resistance when the side plate 2 rotates. The other end of the top of the fixed plate 1 is installed with a handrail 3. The handrail 3 is in an inverted C shape. A sponge is provided on the upper end of the handrail 3. When the trainee bends down, the handrail 3 supports the trainee's waist. The sponge on the handrail 3 serves to increase the comfort of the trainee's waist.

[0022] like Figure 3 As shown, a threaded rod 6 is rotatably installed inside the side panel 2, and a connecting block 7 is slidably connected to the outer side of the threaded rod 6. The top of the connecting block 7 is connected to the bottom end of the support plate 8 slidably connected to the top of the side panel 2, and the movement of the support plate 8 when the threaded rod 6 rotates is achieved through the connecting block 7. A sliding hole is provided on the top of the side panel 2, and the sliding hole is slidably connected to the outer side of the connecting block 7. The sliding hole plays the role of limiting the connecting block 7, so that the connecting block 7 can only slide back and forth in a straight line, and the threaded rod 6 plays the role of adjusting the position of the support plate 8, which is suitable for trainers of different heights. A rotating hole is provided at the end of the side panel 2 away from the handrail 3, which is rotatably connected to the threaded rod 6 and extends out of the rotating hole. A handle is installed on the end of the threaded rod 6 extending out of the rotating hole. The added description of the threaded rod 6 serves to facilitate the trainer to rotate the threaded rod 6.

[0023] like Figure 3 As shown, a sliding groove is provided on the side of the two side panels 2 away from each other, and a connecting plate 10 is elastically connected to the sliding groove by a spring 9. The connecting plate 10 is C-shaped and is located on the outside of the side panel 2. A push plate 11 is installed on the upper end of the connecting plate 10. The push plate 11 is located at the upper end of the support plate 8 and does not contact the support plate 8 to avoid the push plate 11 being blocked by the support plate 8 when sliding.

[0024] like Figure 3 and Figure 4As shown, in this embodiment, specifically: the two side panels 2 are away from each other and are close to the end of the top of the handrail 3. The grip 14 is installed, and the grip 14 serves to increase the hand contact for the trainee. One end of one push plate 11 is rotatably installed with a lever 12, and one end of the other push plate 11 is installed with a fixed block 13. The top of the fixed block 13 is provided with a slot, and the slot is adapted to the size of the lever 12. When the lever 12 is stuck in the slot of the fixed block 13, the positions of the two push plates 11 are limited, thereby increasing the sliding stability of the push plates 11.

[0025] like Figure 1 and Figure 4 As shown, in this embodiment, specifically: a limiting plate 4 is rotatably installed at the middle end of the top of the fixed plate 1, and a connecting rod 15 corresponding to the position of the limiting plate 4 is installed at one end of the handrail 3, and a mutually attractive magnetic piece 16 is embedded on the side where the limiting plate 4 is squeezed and in contact with the connecting rod 15. The magnetic piece 16 increases the stability of the connection between the limiting plate 4 and the connecting rod 15, and realizes the storage of the limiting plate 4. The size of the limiting plate 4 is the same as the gap between the two side panels 2 when they are parallel to each other. The limiting plate 4 has the same thickness as the side panel 2. The limiting plate 4 is located between the two side panels 2, which prevents the gap between the side panels 2 from getting stuck on the trainee.

[0026] Working principle: when in use, place the device in the designated position, merge the two side panels 2, and then rotate the lever 12 so that the lever 12 is stuck in the slot of the fixed block 13. At this time, the two push plates 11 are fixed to each other, and the trainee sits on the side panels 2 to perform sit-up front-drive training. Rotate the threaded rod 6 to drive the connecting block 7 and the support plate 8 to move so that the support plate 8 fits the soles of the trainee's feet. The trainee bends over and straightens his hands, and pushes the push plate 11 with his hands. The push plate 11 drives the connecting plate 10 to slide, thereby stretching the trainee's waist, back, buttocks, back of thighs and calves. When the push plate 11 is not under force, the connecting plate 10 is pushed back to its original position by the spring 9, which is convenient The next trainee uses it, rotates the lever 12 in the opposite direction to release the limit between the two push plates 11, unfolds the two side plates 2, and then rotates the limit plate 4 so that the limit plate 4 is stuck between the two side plates 2. The two side plates 2 are fixed by the limit plate 4. Then the trainee stands on the two side plates 2 and holds the grip bar 14 with both hands to perform split training, thereby stretching the ligaments of the front thighs, buttocks, abdomen, waist, hands and other parts of the trainee. The trainee stands on the end of the fixed plate 1 away from the side plates 2 and performs the waist bending movement. The trainee's waist is supported by the handrail 3. The sponge on the handrail 3 increases the comfort of the trainee's waist, thereby stretching the trainee's waist and ligaments.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
