[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] A butterfly arm structure for a multifunctional fitness equipment includes a main body 6, a seat 5, and butterfly arm structures. The seat 5 is mounted on the main body 6, and two butterfly arm structures are mirror-image mounted on the main body 6. The seat 5 is positioned between the two butterfly arm structures. The butterfly arm structure can exercise the user's arms and chest.

[0024] The butterfly arm structure includes a fixed rod 11, a bent arm 1, a first handle 2, a bent tube 8, and a second handle 7. The fixed rod 11 is connected to the main body 6, the bent arm 1 is fixedly connected to the fixed rod 11, and the first handle 2 is fixedly connected to the end of the bent arm 1 away from the fixed rod 11. A fixed ring 4 is fixedly connected to the bent tube 8, and a positioning rod 10 is inserted into the fixed ring 4. A sleeve 3 is fitted onto the fixed rod.

[0025] One end of the positioning rod 10 abuts against the side of the fixing ring 4 away from the bent arm 1. The first handle 2 is fixedly connected to an extension rod 14, which is located in the bent arm 1. The other end of the positioning rod 10 is inserted into the bent arm 1 and threaded into the extension rod 14. The sleeve 3 is clamped between the fixing ring 4 and the bent arm 1. The fixing rod 11 and the first handle 2 are on the same horizontal line. With the cooperation of the fixing rod 11, the threaded hole, and the sleeve 3, the bent tube 8 is fixedly installed on the bent arm 1. The second handle 7 is fixedly connected to the end of the bent tube 8 away from the fixing ring 4.

[0026] A flexible clip 9 is detachably connected to the curved arm 1, and the flexible clip 9 is connected to the curved tube 8. When the second handle 7 is not in use, the curved tube 8 is in its initial position. At this time, the flexible clip 9 clamps the curved tube 8, which restricts the rotation of the curved tube 8 and prevents it from interfering with the user's use of the first handle 2. The cross-section of the flexible clip 9 consists of two incompletely closed circles that are externally tangent to each other. The shape of the flexible clip 9 can better restrict the rotation of the curved tube 8.

[0027] When the user wants to use the second handle 7 instead of the first handle 2, the threaded fixing rod 11 is loosened. The fixing ring 4 and the bent arm 1 no longer clamp the sleeve 3, allowing the bent tube 8 to rotate around the positioning rod 10. At this point, the bent tube 8 can be rotated to remove it from the elastic clamp 9. Once the bent tube 8 is rotated to the appropriate position, the positioning rod 10 is tightened again, clamping the sleeve 3 between the fixing ring 4 and the bent arm 1. The bent tube 8 is then re-fixed to the bent arm 1, allowing the user to grip the second handle 7 for exercise. Simultaneously, during the rotation of the bent tube 8, the user can freely rotate it to adjust the angle between the bent tube 8 and the bent arm 1, making it more suitable for their own usage habits.

[0028] The extension rod 14 has a threaded hole, and one end of the positioning rod 10 is threaded into the threaded hole. A spring 12 is fixedly installed in the threaded hole. When one end of the positioning rod 10 is pressed against the side of the fixing ring 4 away from the bent arm 1, the other end of the positioning rod 10 presses against the spring 12, and the spring 12 is compressed. At this time, the positioning rod 10 is not easy to loosen, which increases the stability of the positioning rod 10.

[0029] A washer 13 is fitted on the positioning rod 10. The washer 13 abuts against the side of the fixing ring 4 away from the bent arm 1. The end of the positioning rod 10 away from the bent arm 1 abuts against the washer 13. By using the washer 13 and cooperating with the spring 12, the positioning rod 10 is not easy to loosen when the thread is tightened.

[0030] The implementation principle of this embodiment is as follows: During exercise, the user can use the first handle 2. When the user no longer wants to use the first handle 2, the positioning rod 10 is loosened by screwing it loose, and the sleeve 3 is no longer clamped between the fixing ring 4 and the bent arm 1. At this time, the bent tube 8 can be rotated. By rotating the bent tube 8, the bent tube 8 can be removed from the elastic clamp 9. Then, by continuously rotating the bent tube 8, the angle between the bent tube 8 and the bent arm 1 can be adjusted to better suit the user's usage habits. After the angle between the bent tube 8 and the bent arm 1 is properly adjusted, the positioning rod 10 is tightened by screwing it tight, and the sleeve 3 is re-clamped between the fixing ring 4 and the bent arm 1. At the same time, under the action of the spring 12 and the washer 13, the positioning rod 10 is not easy to loosen, and the bent tube 8 is re-fixed on the bent arm 1. At this time, the user can use the second handle 7 for exercise, and the state of the second handle 7 is in line with the user's usage habits, achieving the effect of conveniently switching the use state of the butterfly arm handle according to the user's usage habits.
