[0024] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0025] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0026] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0027] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0028] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] Reference Figure 1 The descender comprises a buckle body 100, which comprises a trapezoidal portion 101, an annular portion 102, and a connecting ring 103. Two through holes 104 are provided on the trapezoidal portion 101, and the projection of the through holes 104 on the horizontal plane is an elliptical structure. Three parallel side plates 105 are provided between the two through holes 104 and on the side away from each other, and two side grooves 106 are formed between the three parallel side plates 105, and the side grooves 106 are arranged in a U-shaped structure. One side of the bottom wall of the two side grooves 106 is respectively connected to the outer edge of one side of the two through holes 104, and the connection is smooth. Friction protrusions 107 are provided on the side walls of the side grooves 106. The connecting ring 103 is located on one side of the side groove 106, and the connection between the annular portion 102 and the side groove 106 is smooth. A notch 108 is provided on the buckle body 100, which passes through the buckle body 100 and is connected to the through hole 104.

[0030] In one embodiment, friction protrusions 107 are symmetrically positioned at the junction of the bottom wall and the two side walls of the side groove 106. The protrusions are arranged in an inclined configuration, with the sides of the protrusions near each other being close together at the bottom and separated from each other at the top. This creates a V-shaped gap between the two friction protrusions 107. When a rope is positioned within the side groove 106, friction is applied to the rope by the friction protrusions 107. The V-shaped structure formed between the two friction protrusions 107 ensures friction when the rope is inserted into the side groove 106 and pulled toward the bottom wall of the side groove 106.

[0031] Reference Figure 2 In one embodiment, a section of the rope passes through one of the through holes 104 and a lock buckle is connected to the other section. One end of the rope is inserted into the through hole 104. When in use, the rope is tightened so that the rope is embedded between the two friction protrusions 107. The rope is clamped and locked by the friction protrusions 107.

[0032] Reference Figure 3 In another embodiment, the rope passes through the annular portion 102, and at the same time, one section of the rope passes through one of the through holes 104 and is connected to a lock buckle. When in use, the rope is telescoped through the annular portion 102, and the rope is guided in the annular portion 102 to prevent the buckle body 100 from shaking when the rope swings.

[0033] Reference Figure 4 In another embodiment, the rope passes through the annular portion 102, and at the same time, one section of the rope passes through one of the through holes 104 and a lock buckle is connected to the other section. One end of the rope passes through the connecting ring 103 to limit the rope. When in use, the rope is locked by pulling the end of the rope that has passed through, so as to prevent the rope from being accurately inserted into the through hole 104 when being pulled.

[0034] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
