[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1-2 , the embodiments of the present utility model provide a technical solution: a mechanism for achieving fastening and loosening by rotational motion, including a disc 1. A large gear 2 is provided at the central position on the reverse side of the disc 1, and four receiving and combining mechanisms 3 are evenly provided on the front side of the disc 1.

[0022] The receiving and combining mechanism 3 includes a first rotating mounting seat 301, a pressing mechanism 302, and a receiving and combining frame 303. The other end of the pressing mechanism 302 is fixedly connected with a small gear 4. By setting the large gear 2, small gear 4, pressing mechanism 302, and receiving and combining frame 303, first, by releasing the pressing mechanism 302, the small gear 4 is fixedly connected with the pressing mechanism 302. Then, the large gear 2 drives the small gear 4 to rotate, causing the pressing mechanism 302 to rotate. Further, the pressing mechanism 302 drives the receiving and combining frame 303 to rotate, thereby changing the receiving and combining direction of the receiving and combining mechanism 3. Then, by pressing the pressing mechanism 302, the large gear 2 drives the disc 1 to rotate, so that the opening and closing fastening mechanism 8 rotates and moves inside the track 6, causing the opening and closing fastening mechanism 8 to open and fasten with the receiving and combining mechanism 3, achieving opening and fastening at different angles, avoiding the situation that the traditional rotating fastening and loosening mechanism is easily restricted and unable to be used in some special cases, and improving the practicability of the device.

[0023] The inner ring of the first rotating mounting seat 301 is fixedly connected with the pressing mechanism 302, the side surface of the pressing mechanism 302 is fixedly connected with the receiving and combining frame 303, and the outer ring of the first rotating mounting seat 301 is fixedly connected with the disc 1.

[0024] The pinion gear 4 is arranged on the reverse side of the disc 1, and the surface of the pinion gear 4 is meshed and connected with the large gear 2. By setting the pressing mechanism 302, the conversion between the fixed connection of the pinion gear 4 and the pressing mechanism 302 and the fixed connection of the pinion gear 4 and the disc 1 is realized.

[0025] Four positioning mechanisms 5 are evenly arranged on the front surface of the disc 1. The positioning mechanism 5 includes a second rotary mounting seat 501, a positioning rod 502, and a positioning frame 503. The outer ring of the second rotary mounting seat 501 is fixedly connected with the disc 1, and the positioning frame 503 is arranged on the reverse side of the disc 1.

[0026] The inner ring of the second rotary mounting seat 501 is fixedly connected with the positioning rod 502, and the other end of the second rotary mounting seat 501 is fixedly connected with the positioning frame 503. By setting the positioning mechanism 5, the positioning function of the device is realized.

[0027] A track 6 is opened inside the large gear 2, four openings 7 are evenly opened inside the disc 1, and an opening and closing fastening mechanism 8 is evenly arranged on the front surface of the disc 1. The opening and closing fastening mechanism 8 includes a swing wheel 801, a third rotary mounting seat 802, a rotating rod 803, a connecting plate 804, and a fastening head 805.

[0028] The side surface of the swing wheel 801 is fixedly connected with the third rotary mounting seat 802, the inner ring of the third rotary mounting seat 802 is fixedly connected with the rotating rod 803, the side surface of the rotating rod 803 is fixedly connected with the connecting plate 804, and the side surface of the connecting plate 804 is fixedly connected with the fastening head 805.

[0029] The surface of the swing wheel 801 is slidably connected with the track 6, and the surface of the opening and closing fastening mechanism 8 passes through the opening 7. By setting the opening and closing fastening mechanism 8 and the receiving mechanism 3, the large gear 2 drives the disc 1 to rotate, so that the swing wheel 801 rotates and moves inside the track 6, thereby enabling the opening and closing fastening mechanism 8 to rotate and move, and enabling the fastening head 805 to open and fasten with the receiving frame 303, realizing the fastening and loosening of the device by rotation.

[0030] Working principle: When in use, when opening and fastening at different angles, first release the pressing mechanism 302 so that the small gear 4 is fixedly connected to the pressing mechanism 302. Then rotate the large gear 2. The surface of the large gear 2 drives the small gear 4 to rotate. The side of the small gear 4 drives the pressing mechanism 302 to rotate. The side of the pressing mechanism 302 drives the receiving frame 303 to rotate, so that the opening and fastening angles of the receiving frame 303 are changed. Then press the pressing mechanism 302 again so that the small gear 4 is fixedly connected to the disc 1. Then rotate the large gear 2. The large gear 2 indirectly drives the disc 1 to rotate through the small gear 4. Since the position of the opening and fastening mechanism 8 remains unchanged all the time, the opening and fastening mechanism 8 rotates in the opposite direction relative to the disc 1. Thus, the swing wheel 801 rotates and moves inside the track 6. The side of the swing wheel 801 drives the rotating rod 803 to rotate. The side of the rotating rod 803 drives the connecting plate 804 to rotate. The side of the connecting plate 804 drives the fastening head 805 to rotate, so that the fastening head 805 opens and fastens with the receiving frame 303, realizing opening and fastening at different angles.
