There are positioning grooves 25 distributed in the slide groove 24 along the length direction of the slide groove 24. The two ends of the second folding support frame 23 are inserted into the slide groove 24. The second folding support frame 23 is provided with a positioning protrusion 26 that can be inserted into the positioning groove 25. When in the folded state, the positioning protrusion 26 is inserted into the front positioning groove 25; when in the unfolded state, the positioning protrusion 26 is inserted into the tail positioning groove 25.

[0055] The twelfth embodiment, as shown in Figures 14 and 15, differs from the first embodiment in that the first folding support frame 22 and the second folding support frame 23 have different shapes and hinge structures. Specifically, the second folding support frame 23 has an approximately U-shaped opening, the open end of which is hinged to the first folding support frame 22. A first rotation axis hole 27 is provided at one end of the first folding support frame 22. The first rotation axis hole 27 is on a side wall away from the notch 11. The first rotation axis hole 27 can be provided on both the left and right sides of the first folding support frame 22. A second rotation axis hole 28 is provided at one end of the second folding support frame 23, and second rotation axis holes 28 are provided at both ends of the opening of the second folding support frame 23. A rubber sleeve 29 is sleeved in the first rotating shaft hole 27, and a rotating shaft 30 with one end inserted into the rubber sleeve 29 is provided in the second rotating shaft hole 28. A first anti-slip protrusion 301 that is squeezed against the rubber sleeve 29 and a second anti-slip protrusion 302 that is squeezed against the second rotating shaft hole 28 are respectively provided on the outer circumference of the rotating shaft 30 at one end in the rubber sleeve 29 and the other end in the second rotating shaft hole 28. The first anti-slip protrusion 301 is interference fit with the rubber sleeve 29 and is squeezed, and the rotating shaft 30 can drive the rubber sleeve 29 to rotate. The second anti-slip protrusion 302 is interference fit with the second rotating shaft hole 28 and is squeezed, and the second folding support frame 23 can drive the rotating shaft 30 to rotate. The first anti-slip protrusion 301 and the second anti-slip protrusion 302 are strip-shaped and extend along the axial direction of the rotating shaft 30. During installation, the rotating shaft 30 is inserted into the rubber sleeve 29 from the second rotating shaft hole 28, that is, one end of the first anti-slip protrusion 301 is first passed through the second rotating shaft hole 28 and then inserted into the rubber sleeve 29. The first anti-slip protrusion 301 is spaced apart from the second anti-slip protrusion 302. The first anti-slip protrusion 301 and the second anti-slip protrusion 302 are independently arranged and not connected. The first anti-slip protrusion 301 and the second anti-slip protrusion 302 are provided on the outer circle of the rotating shaft 30. The multiple first anti-slip protrusions 301 form a circle, and the multiple second anti-slip protrusions 302 are arranged on the outer circle of the rotating shaft 30. 02 form a circle, the protrusion height of the first anti-slip protrusion 301 is smaller than the protrusion height of the second anti-slip protrusion 302. It can be seen from the figure that the first anti-slip protrusion 301 is thinner than the second anti-slip protrusion 302. In this way, the outer diameter of the circle formed by the first anti-slip protrusion 301 is smaller than the outer diameter of the circle formed by the second anti-slip protrusion 302. When the first anti-slip protrusion 301 passes through the second rotating shaft hole 28, the second rotating shaft hole 28 will not be squeezed too much, and there is still a margin for interference fit when the second anti-slip protrusion 302 passes through the second rotating shaft hole 28.
