Preferably, the elastic clamp 250 can be formed integrally with the connecting plate 230. Similar to the first embodiment, the self-rivet 240 penetrates the bearing component 210 along the first direction D1, the self-rivet 240 penetrates the mounting hole 232 along the first direction D1 and is embedded in the handrail guide rail 14 of the escalator 1. The self-rivet 240 acts as a rotating shaft of the bearing component 210, and the self-rivet 240 is partially inserted into the side wall of the handrail guide rail 14 and slightly expands in the handrail guide rail 14, so that the bearing component 210 is fastened to the side wall of the handrail guide rail 14 through the self-rivet 240.

[0073] In the second embodiment, the bearing assembly 200 is fastened to the side wall of the handrail guide rail 14 through the self-rivet 240, and the fastening effect between the bearing assembly 200 and the side wall of the handrail guide rail 14 is further enhanced through the elastic clamp 250.

[0074] Figure 6 A partial schematic view of a handrail 10 according to a third embodiment of the present application is shown, for the sake of brevity, only the technical features different from the first and second embodiments in the third embodiment are described in detail, and the technical features same as the first and second embodiments in the third embodiment are not described in detail.

[0075] Specifically, the spring ball plunger 340 has a hollow cylindrical body 342 extending along the first direction D1 and protrusions 344 (for example, the protrusions 344 can have the shape of a ball) protruding outward from both ends of the body 342, respectively, and the protrusions 344 are embedded into the handrail guide rail 14 of the escalator 1 through the mounting hole 332. By embedding the protrusions 344 of the spring ball plunger 340 into the handrail guide rail 14 of the escalator 1, the bearing assembly 100 can be installed to the handrail guide rail 14, and there is no need to set a corresponding mounting structure (for example, a threaded hole) on the handrail guide rail 14, avoiding the structural strength of the handrail guide rail 14 from being reduced due to the existence of the mounting structure, thereby improving the structural stability of the escalator 1. In addition, the body 342 of the spring ball plunger 340 can act as a rotating shaft for the rotation of the bearing component 310.

[0076] Preferably, the spring ball plunger 340 can further comprise a resilient means 346 inside the hollow body 342, which is configured to bias the protrusion 344 outwardly in the first direction D1. Before the bearing assembly 300 is installed, the protrusion 344 can be first locked in a retracted position by an external force, and after the bearing assembly 300 is placed in position, the external force is removed to release the protrusion 344, so that the protrusion 344 is ejected outwardly under the action of the resilient means 346 and embedded into the side wall of the handrail guide rail 14, thereby fastening the bearing assembly 300 to the handrail guide rail 14.

[0077] In the third embodiment, the bearing assembly 300 is fastened to the side wall of the handrail guide rail 14 by the spring ball plunger 340.
