The spring 10, buffer plate 11, support rod 12, and limiting disc 13 provide cushioning protection when the L-shaped plate 7 contacts the limiting plate 6. The support assembly 14 facilitates the movement and support of the device, and allows for adjustment of its horizontal position. With the above structure, this chest and abdominal core muscle fitness equipment has the advantage of adjustable function during use, solving the problem of traditional chest and abdominal core muscle fitness equipment lacking adjustable function, thus meeting the needs of exercisers.

[0022] As a technical optimization of this utility model, the support component 14 includes a stud 141, a support protrusion 142 is threadedly connected to the outer surface of the stud 141, and a caster wheel 143 is movably connected to the bottom of the stud 141.

[0023] In this embodiment, by setting studs 141, support protrusions 142 and casters 143, the device can be easily moved and supported, and its horizontal state can be adjusted.

[0024] As a technical optimization of this utility model, a locking plate is provided on one side of the universal wheel 143, and the top of the stud 141 is fixedly connected to the connection of the adjustment box 1.

[0025] In this embodiment, the universal wheel 143 can be limited by setting a locking plate.

[0026] As a technical optimization of this utility model, the bottom of the supporting convex cylinder 142 is fixedly connected with an anti-slip pad, and the number of anti-slip pads is four.

[0027] In this embodiment, by setting an anti-slip pad, the friction of the supporting protrusion 142 can be increased, thereby improving the stability of placement.

[0028] As a technical optimization of this utility model, a guide plate 15 is fixedly connected to the bottom of the rectangular plate 4, and a guide groove 16 that works with the guide plate 15 is opened at the bottom of the inner cavity of the adjustment box 1. The outer surface of the guide plate 15 is slidably connected to the inner surface of the guide groove 16.

[0029] In this embodiment, by setting the guide plate 15 and the guide groove 16, the rectangular plate 4 can be guided and limited.

[0030] As a technical optimization of this utility model, the front and rear positions of the top of the adjustment box 1 are fixedly connected with slide rails 17 that cooperate with the limiting plate 6 and the L-shaped plate 7. The outer surface of the slide rails 17 is slidably connected to the inner surface of the limiting plate 6 and the L-shaped plate 7 respectively.

[0031] In this embodiment, the slide rail 17 can be used to guide and support the limiting plate 6 and the L-shaped plate 7.

[0032] As a technical optimization of this utility model, a protective pad 18 is fixedly connected to the right side of the top of the adjustment box 1, and a slide cylinder 19 for use with the support rod 12 is embedded in the front and rear positions of one side of the L-shaped plate 7. The inner surface of the slide cylinder 19 is slidably connected to the outer surface of the support rod 12.

[0033] In this embodiment: by setting the protective pad 18, the comfort of the device can be improved; by setting the slide cylinder 19, the support rod 12 can be guided and supported.

[0034] Working principle: The operator moves the device to the designated exercise position using the casters 143. Then, the operator rotates the support protrusions 142 in sequence, causing the support protrusions 142 to move the anti-slip pads downwards and contact the ground. This allows the four support protrusions 142 and the anti-slip pads to work together to support the device and adjust its level.

[0035] When the intensity of the chest and abdominal core muscle training needs to be adjusted according to the exerciser's training requirements, the exerciser rotates the handle 3, causing the screw 2 to rotate on the inner surface of the rectangular plate 4. This causes the rectangular plate 4 to move the drive plate 5, which in turn causes the limiting plate 6 to slide on the outer surface of the slide rail 17. This allows the limiting plate 6 to move to a suitable limiting position, thus adjusting the movement distance of the L-shaped plate 7. Next, the exerciser kneels on top of the protective pad 18 and then grasps the handles 9 on both sides of the positioning plate 8. With arms straight and buttocks raised, slowly push the handle 9 to the left, causing the handle 9 to move the positioning plate 8 and L-shaped plate 7 on the outer surface of the slide rail 17. This causes the L-shaped plate 7 to move the buffer plate 11 and press against the limiting plate 6. At the same time, the buffer plate 11 moves in the opposite direction to compress the spring 10, thereby providing cushioning and protection at the connection between the L-shaped plate 7 and the limiting plate 6, improving the comfort of the exercise. Then, follow the above steps to perform the back-and-forth movement, keeping your arms straight during the back-and-forth movement, thus achieving a fitness exercise for the core muscles of the chest and abdomen.

[0036] When further strengthening the exercise intensity is needed, the exerciser can stand directly on the right side of the device, hold the handles 9 on both sides of the positioning plate 8 with both hands, then straighten their arms, stick out their buttocks, and stand on the ground with both legs straight, that is, fold their body up. Then, slowly push the handles 9 to the left, so that the handles 9 drive the positioning plate 8 and the L-shaped plate 7 to slide on the outer surface of the slide rail 17. Then, repeat the above steps to make a back-and-forth motion. During the back-and-forth motion, the legs and arms should be kept straight, so as to further strengthen the core muscles of the chest and abdomen. The device is simple to operate and easy to adjust for exercise and fitness, thus meeting the needs of exercisers.
