[0027] As Figures 1-4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the folding rod 5 includes a fixed rod 51, a card slot 52 is opened on one side of the bottom of the fixed rod 51, a rotating rod 54 is connected through one side of the card slot 52, a connecting component 53 is fixedly connected to one side of the rotating rod 54, and a movable rod 55 is movably connected to one side of the connecting component 53 through the rotating rod 54.

[0028] The side view of the connecting component 53 is in a convex shape, and one end of the connecting component 53 and the fixed rod 51 are also folded by 90° through a rotating rod.

[0029] In this embodiment, through the combined action of the fixed rod 51, the connecting component 53, the rotating rod 54 and the movable rod 55, the device can be made more convenient to use. A card slot 52 is provided at the bottom of the fixed rod 51, and the card slot 52 is connected to the connecting component 53 through the rotating rod 54.
