DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of the utility model protection.

[0025] As Figures 1-8The utility model provides a baby stroller folding device, it includes cylindrical hollow pipe 1 and rivet 5, the central region of cylindrical hollow pipe 1 is provided with shrinkable tube 2, two movable pins 3 are provided in cylindrical hollow pipe 1, symmetrical sleeve sets with driving pipe 4 on cylindrical hollow pipe 1, driving pipe 4 is sleeved with protective sleeve pipe 7, two driving pipes 4 are commonly sleeved with rotating sleeve pipe 6;

[0026] Limiting groove 11 and sliding groove 12 are arranged on cylindrical hollow pipe 1;

[0027] One end of movable pin 3 is provided with through slot one 31.

[0028] Arc-shaped sliding groove 42 is arranged on driving pipe 4, through slot two 41 is arranged on one side of arc-shaped sliding groove 42 of driving pipe 4, symmetrical slide rail one 43 is arranged in driving pipe 4, and driving pipe 4 is slidably connected with cylindrical hollow pipe 1 through slide rail one 43;

[0029] Button 61 is arranged on rotating sleeve pipe 6, arc-shaped slide rail 62 corresponding with arc-shaped sliding groove 42 is arranged on the inner wall of rotating sleeve pipe 6, and hand-held rod 63 is rotatably connected to the bottom of rotating sleeve pipe 6;

[0030] Symmetrical slide rail two 71 is arranged in protective sleeve pipe 7, and protective sleeve pipe 7 is slidably connected with cylindrical hollow pipe 1 through slide rail two 71;

[0031] Rivet 5 is arranged through through slot two 41, limiting groove 11 and through slot one 31.
