Please refer to FIG. 13 to FIG. 19. FIG. 13 is a diagram of the adjusting mechanism 34′ according to a second embodiment of the present invention. FIG. 14 is an exploded diagram of a part of the adjusting mechanism 34′ according to the second embodiment of the present invention. FIG. 15 is a diagram of a part of the adjusting mechanism 34′ according to the second embodiment of the present invention. FIG. 16 and FIG. 17 respectively are diagrams of the adjusting mechanism 34′ in different modes according to the second embodiment of the present invention. FIG. 18 is a sectional view of the adjusting mechanism 34′ shown in FIG. 16. FIG. 19 is a sectional view of the adjusting mechanism 34′ shown in FIG. 17.
The adjusting mechanism 34′ includes the first engaging component 52, the second engaging component 54, the driving component 58, a cable 61, the third engaging component 62, an elastic component 64 and an actuating component 66.

The third engaging component 62 is movably disposed between the first engaging component 52 and the second engaging component 54. The actuating component 66 is slidably disposed between the second engaging component 54 and the third engaging component 62. Two ends of the cable 61 are respectively connected to the driving component 58 and the actuating component 66, so that the driving component 58 can control a movement of the third engaging component 62 via the cable 61 and the actuating component 66. When the driving component 58 is pulled, the actuating component 66 slides relative to the seat body 26 to disengage the third engaging component 62 from the second engaging component 54, and the seating component 24 can rotate relative to the supporting component 12 by the adjusting mechanism 34′. Besides, two ends of the elastic component 64 are respectively connected to the third engaging component 62 and the first engaging component 52. The elastic component 64 can recover the actuating component 66 and the third engaging component 62 to initial positions since the external force applied to the driving component 58 is removed. It should be mentioned that the user can adjust the inclined angle of the seating component 24 via the driving component 58 by single hand control.
The first engaging component 52 and the second engaging component 54 respectively include a first internal tooth structure and a second internal tooth structure, and the third engaging component 62 is a locking gear matched with the first internal tooth structure and the second internal tooth structure accordingly. The locking gear driven by the actuating component 66 is movably disposed between the first internal tooth structure and the second internal tooth structure. The second engaging component 62 includes a cone structure 68. The actuating component 66 includes an inclined guiding structure 70 slidably abutting against the cone structure 68. The inclined guiding structure 70 includes a first end 701 and a second end 703 opposite to each other, and a width W1 of the first end 701 is greater than a width W2 of the second end 703. As shown in FIG. 16 and FIG. 18, the third engaging component 62 moves to the first position, the first end 701 of the inclined guiding structure 70 abuts against a bottom 681 of the cone structure 68, and the third engaging component 62 contacts against constraining walls 261 of the seat body 26. Meanwhile, the third engaging component 62 is simultaneously engaged with the second engaging component 54 and the first engaging component 52. Due to structural interference between the first engaging component 52, the second engaging component 54 and the third engaging component 62, the adjusting mechanism 34′ can constrain the relative movement between the seating component 24 and the supporting component 12.
As shown in FIG. 17 and FIG. 19, the driving component 58 is utilized to actuate unlock function of the adjusting mechanism 34′, and the inclined guiding structure 70 slides relative to the constraining walls 261 of the seat body 26 to push the cone structure 68. Due to width difference between the ends of the inclined guiding structure 70, the third engaging component 62 moves along a center axial direction of the third engaging component 62 and is switched to the second position; in the meantime, the second end 703 of the inclined guiding structure 70 abuts against a top 683 of the cone structure 68. When the third engaging component 62 is switched to the second position, the locking gear of the third engaging component 62 is engaged with the first internal tooth structure of the first engaging component 52 and separated from the second engaging component 54. Thus, the seating component 24 can rotate relative to the supporting component 12 via the adjusting mechanism 34′ to adjust the inclined angle of the seat body 26.
Please refer to FIG. 20 to FIG. 22. FIG. 20 to FIG. 22 respectively are diagrams of the adjusting mechanism 34′ indifferent rotary modes according to the second embodiment of the present invention. The second internal tooth structure of the second engaging component 54 includes a plurality of engaging teeth 72 and a plurality of constraining teeth 74. Each of the constraining teeth 74 is arranged between the adjacent engaging teeth 72. A height of the constraining tooth 74 is greater than a height of the engaging tooth 72. An amount of the constraining tooth 74 is smaller than an amount of the engaging tooth 72, and the second internal tooth structure includes at least one constraining tooth 74. The locking gear of the third engaging component 62 includes a plurality of engaged slots 76 and a plurality of constraining slots 78. Each of the constraining slots 78 is arranged between the adjacent engaged slots 76. A depth and a width of the constraining slot 78 is greater than a depth and a width of the engaged slot 76. An amount of the constraining slot 78 is preferably equal to an amount of the constraining tooth 74. The constraining tooth 74 is movably disposed inside the corresponding constraining slot 78 no matter where the third engaging component 62 is located (such as switching to the first position or the second position). Therefore, the inclined angle of the seating component 24 relative to the supporting component 12 can be adjusted by the adjusting mechanism 34′, and a value of the inclined angle is designed according to parameters of the constraining tooth 74 and the constraining slot 78. For example, adjustable variation of the adjusting mechanism 34′ becomes more since the third engaging component 62 has the wider width of the constraining slot 78.
