[0021] Further improvement, such as Figs. 1-3As shown in the figure, the card foot 3 comprises two support feet 30 which are arranged in parallel and spaced apart, that is, the card foot 3 is arranged as two separate support feet 30, and the gap between the two support feet 30 constitutes the card foot card slot, the bottom surface of the protective sleeve 2 constitutes the bottom of the card foot card slot, and the two support feet 30 constitute the walls of the card foot card slot. At this time, the width of the gap is slightly smaller than the width of the stretcher handrail or the bed handrail, and when the handrail is clamped into the card foot card slot, an interference fit is formed to ensure the stability of the handrail after clamping with the card foot card slot. In order to avoid the support feet 30 and the handrail from being separated due to vehicle shaking after clamping, the upper part of the relative surface of the two support feet 30 is provided with an elastically deformable elastic protrusion 33 at the corresponding position, that is, the elastic protrusion 33 is arranged on both of the two support feet 30, and the elastic protrusions 33 on the two support feet 30 are opposite and at the same height. In this way, the two elastic protrusions 33, the part of the two support feet 30 above the elastic protrusion 33, and the bottom surface of the protective sleeve 2 constitute a containing space, which is used to contain the handrail. When the handrail is clamped into the containing space, the elastic protrusion 33 will be first squeezed to deform and then clamped in. After the handrail is clamped, the squeezing force on the elastic protrusion 33 disappears, and the elastic protrusion 33 returns to its original state to limit the handrail in the containing space. The elastic protrusion 33 can be arranged as an arc-shaped protrusion with a long strip-shaped cross section and the same direction as the axis of the card slot 10. In order to facilitate the clamping of the handrail into the card foot card slot and maintain the stability of the structure, the support feet 30 are arranged as elastically deformable support feet. At this time, the gap between the two support feet 30 can be smaller, and the elastic deformation of the support feet 30 is used to maintain the close clamping with the handrail. The support feet 30 can be made of the same material as the supporting plate 1. At this time, the two support feet 30 can be arranged in a structure in which the opposite surfaces are in abutment with each other to ensure the stability of the structure after the handrail is clamped between the two support feet 30. The two support feet 30 are connected to the protective sleeve 2 on the side away from each other at the top end, and the upper end of the opposite surface of the two support feet 30 is provided with a slope 31 or an inwardly recessed arc surface which forms a containing cavity 32 with the bottom surface of the protective sleeve 2, that is, each support foot 30 is provided with a slope 31 or an arc surface at the upper end. The slopes 31 or arc surfaces on the two support feet 30 are opposite and at the same height, and the two slopes 31 or arc surfaces and the bottom surface of the protective sleeve 2 constitute the containing cavity 32, in which the handrail is fixed in position. When the handrail is clamped into the containing cavity 32, an action is required to squeeze and separate the two support feet 30 which are in abutment with each other. After the handrail is clamped into the containing cavity 32, the squeezing force on the two support feet 30 disappears, and the two support feet 30 return to their original state and again abut with each other to maintain the stability of the handrail in the containing cavity 32.In order to increase the friction between the handrail and the slope 31 or arc, the top surface protrusions 310 are arranged on the slope 31 or arc, the top surface protrusions 310 are arranged on the slope 31 or arc of the two supporting feet 30, the top surface protrusions 310 are integrally formed with the supporting feet 30, the top surface protrusions 310 can be arranged in strip shape or spherical shape according to different requirements, and a plurality of top surface protrusions 310 are arranged at intervals, the top surface protrusions 310 are arranged in an interlaced manner on the two supporting feet 30, and the structural stability of the handrail clamped in the accommodating cavity 32 is further ensured.
