The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a kind of collapsing mechanism of baby stroller, it comprise front foot pipe 1, handle pipe 2, shell 3, end cap 4, under amount to pinion stand 5, lower gear 6, on amount to pinion stand 7, cog 8, slide block 9 and pressure spring 10,

Front foot pipe 1 arranged on described shell 3 leading to sliding eye 31, handle pipe 2 the fixed interface 33 of pipe after pipe slide-and-guide hole 32 and mounting, cotter way 34 is arranged in shell 3;

As shown in Figure 4, described slide block 9 comprises driving coupling end 91, the shank 92 that is positioned at slider bottom that is positioned at slider top and is arranged on the spring cavity 93 on slide block 9 that a spring perch 94 is arranged in spring cavity, connects the pilot hole 95 of spring cavity;

Described front foot pipe 1 with under amount to pinion stand 5 and be fixedly connected with, lower gear 6 is fixed on down to be amounted on pinion stand 5; One lower rotary shaft and lower gear 6 with under amount to pinion stand 5 and be fixedly connected with, lower rotary shaft end and shell 3 and end cap 4 pivot joints.
