FIG. 16 is an exploded diagram of the operating structure 70 in FIG. 13 in a different view according to the second embodiment of the present invention. The engaging structure 70 of the second embodiment is similar to one of the first embodiment mentioned above, and detailed description is not reiterated. Differences between the second embodiment and the first embodiment are struotures and arrangements of the operating structure. In the second embodiment, the handle height adjusting mechanism includes an operating structure 80 for driving the two engaging structures 70 at the same time. The operation of the operating structure 80 is introduced as follows.

Specifically, the operating structure 80 includes a button 81, a first connecting pillar 821, a second connecting pillar 822 and a connecting housing 83. The connecting housing 83 includes a first housing 831 and a second housing 832 engaged with each other at a center of the crossbar 10, and an installing chamber is formed between the first housing 831 and the second housing 832. An opening is formed on a side of the connecting housing 83 and communicated to the installing chamber. The button 81 is slidably disposed in the opening, and a part of the button 81 is stretched out of the connecting housing 83. The first connecting pillar 821 and the second connecting pillar 822 respectively slidably pass through the button 81 and the connecting housing 83. The first connecting pillar 821 and the second connecting pillar 822 are respectively connected to the pulling component 60. The button 81 drives the first connecting pillar 821 and the second connecting pillar 822 to slide in the connecting housing 83 for unlocking the engaging structure 70, as shown in FIG. 3.

A first horizontal slot 83la and a second horizontal slot 831b are disposed on the center of the first housing 831, and the first horizontal slot 831a and the second horizontal slot 831b are arranged in a straight line. Correspondingly, a first horizontal slot 832a and a second horizontal slot 832b are disposed on the center of the second housing 832. The first horizontal slot 831a is corresponded to the first horizontal slot 832a, and the second horizontal slot 831b is corresponded to the second horizontal slot 832b. A first slanting slot 811 and a second slanting slot 812 are disposed on the button 81, and the first slanting slot 811 and the second slanting slot 812 are extended obliguely upward from the center to two upper corners of the button 81. Therefore, the first slanting slot 811 and the first horizontal slots 831a and 832a are intersected, and the second slanting slot 812 and the second horizontal slots 831b and 832b are intersected. After installation, the first connecting pillar 821 slidably passes through the first slanting slot 811, and two ends of the first connecting pillar 821 are slidably contained in the two first horizontal slots 831a and 832a. Correspondingly, the second connecting pillar 822 slidably passes through the second slanting slot 812, and two ends of the second connecting pillar 822 are slidably contained in the two second horizontal slots 831b and 832b. The first connecting pillar 821 and the second connecting pillar 822 are respectively connected to one ends of two pulling components 60, the other ends of the two pulling components 60 are respectively connected to the driving components 73 of the two engaging structures 70. The button 81 can be pressed to drive the two pulling components 60 to move for pulling the two engaging structures 70 tc be unlocked at the same time.

Please refer to FIG. 13 to FIG. 16 and the aforementioned engaging structure 70. The operation of the operating structure 80 is introduced as follows. For adjusting the height of the handle 20 of the stroller, the button 81 of the operating structure 80 is pressed, so that the button 81 slides inward along the connecting housing 83. As the button 81 slides, the button 81 drives the first connecting pillar 821 to slide along the first horizontal slots 83la and 832a, and drives the second connecting pillar 822 to slide along the second horizontal slots 83lb and 832b, so that the first connecting pillar 821 and the second connecting pillar 822 slide toward each other. That is, the first connecting pillar 821 and the second connecting pillar 822 approach each other. As the first connecting pillar 821 and the second connecting pillar 822 slide, the two pulling components 60 are driven for pulling the driving components 73 of the two engaging structures 70, so as to unlock the two engaging portions 743 for adjusting the height of the handle 20.

After finishing the adjustment of the height of the handle 20, the driving components 73 of the two engaging structures can be recovered by the resilient component 72, so as to drive the two pulling components 60 to pull the first connecting pillar 821 to slide along the first horizontal slots 831a and 832a, and to drive the second connecting pillar 822 to slide along the second horizontal slots 831b and 832b in an opposite direction. That is, the first connecting pillar 821 and the second connecting pillar 822 slide away from each other; meanwhile, the button 81 stretches out of the connecting housing 83 again.

The handle height adjusting mechanism of the present invention includes the operating structure 50/80, the pulling component 60, and the engaging structure 70. The operating struotures 50/80 are disposed on the upper end of the upper handle 21 of the stroller, the engaging structure 70 is disposed inside the lower end of the upper handle 21 of the stroller and detaohablLy engaged with the lower handle 22, and the pulling component 60 is oonnected between the operating structures 50/80 and the engaging structure 70.
