[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] An embodiment of the present invention: Figure 1 and Figure 2 As shown, a body-mounted bracket for an underwater propeller includes a fixing bracket 5, a spacer 4, a first strap 2, a second strap 6, and a third strap 3. The fixing bracket 5 has strap holes at its upper and lower ends, and the fixing bracket 5 protrudes upward to form a spacer 4. The spacer 4 has strap holes on both sides, and its upper surface is an arc-shaped connection surface for the propeller 14. The spacer 4 is provided with mounting holes for connecting to the propeller 14, matching the outer contour of the propeller 14. The first strap 2 and the second strap 6 are respectively passed through and mounted in the strap holes at the upper and lower ends of the fixing bracket 5, and connectors are provided at each end of the first strap 2 and the second strap 6. The third strap 3 is passed through and mounted in the strap hole of the spacer 4, and connectors are provided at each end of the third strap 3.

[0024] The fixing bracket of the present invention is designed as an integral part according to ergonomics. There is an anti-skid spacer 4 on the fixing bracket 5. The surface of the spacer 4 is curved and adapted to the shape of the propeller 14. When in use, the propeller 14 is fixed to the spacer 4 by screws 10. The anti-skid spacer 4 itself is elastic and can fit the propeller 14 and the fixing bracket 5 very well. With the spacer 4, the screw 10 will not loosen when the propeller 14 is started underwater and generates vibrations. Therefore, this anti-skid spacer 4 plays the role of anti-skid and shock absorption at the same time, avoiding the loosening of the fixing screws. At the same time, the fixing bracket 5 has three straps at the upper, middle and lower positions. The first strap 2 and the second strap 6 are used to fix to the human body, and the third strap 3 in the middle is fixed to the propeller 14, which can further fix the propeller 14.

[0025] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 3As shown, the spacer 4 is a hollow cuboid with a hollow structure 12 around the mounting hole. The spacer 4 has curved transitions in all four directions: front, back, left, and right. This is to reduce resistance in all four directions when the fixing bracket 5 moves in the water. The spacer 4 is hollow inside and has the hollow structure 12 on the surface. This is to reduce the weight of the fixing bracket 5 while ensuring its strength.

[0026] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 3 As shown, the spacer 4 forms an inclined surface 13 in the forward direction of the propeller 14 after installation. The function of the inclined surface 13 is to divide water when the propeller 14 moves forward, thereby reducing resistance.

[0027] In other specific embodiments of the present invention, the rest is the same as the above embodiment, except that, as shown in FIG. Figure 3 As shown, the spacer 4 is covered with a gasket 1 whose shape and hole position are adapted to the spacer 4, and the gasket 1 is made of silicone. Figure 4 As shown, the spacer 4 can be directly mounted on the spacer 4. The gasket cover 1 is made of silicone material with good elasticity, anti-skid and wear-resistant properties, which can improve the anti-skid and wear resistance of the spacer 4, further improve the anti-skid and shock-absorbing performance, and prevent the fixing screw 10 from loosening.

[0028] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 3 As shown, the cushion cover 1 is provided with a drainage hole 7 in the opposite direction of the forward direction of the propeller 14 after installation. When the user propels underwater, water flows through the drainage hole 7, greatly reducing the resistance of the water to the bracket.

[0029] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 2 As shown, the connector is a Velcro that covers the first strap 2, the second strap 6, and both ends of the third strap 3, ensuring that it can be tightly fixed on any person's arm or leg. Of course, depending on actual needs, a connector such as a buckle with adjustable length can be used instead.

[0030] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 2 As shown, the end of the fixing bracket 5 close to the human body is an arc surface, and a layer of EVA cotton pad 9 is pasted on the arc surface to increase the comfort after the bracket is tied to the human body.

[0031] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 5As shown, the propeller 14 is connected to the spacer 4 on the fixing bracket 5 by screws 10 and is fastened to the fixing bracket 5 by a third strap 3. The middle third strap 3 can effectively reduce the impact of vibration during the starting process of the propeller 14, prevent the screws from loosening, and make the fixation more secure.

[0032] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 2 As shown, the screw 10 is hingedly connected to a pull ring 11 on the end face on the body side, which allows the screw to be tightened manually without using tools. The other end of the screw 10 is connected to the fixed bracket 5 via a spring. This allows the screw to be tightened and will not fall off when it needs to be loosened, preventing it from being lost.

[0033] In other specific embodiments of the present invention, the rest are the same as the above embodiments, except that, Figure 2 As shown, an open retaining ring 8 is installed between the screw 10 and the spacer 4. It increases the friction and tightness of the screw and prevents the screw from loosening under the action of vibration or other external forces.

[0034] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the main technical solution of the present invention are intended to be covered by the scope of protection of the present invention.
