[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting a supporting mechanism, the seat body can be supported and limited by this mechanism, and the first fixing sleeve in the mechanism drives the first penetrating rod to move horizontally, so that the first support frame is limited and retracted. This process can be caused by the first penetrating rod and the second penetrating rod being engaged with the first support frame and the second support frame through the gear sleeve at the contact point. Therefore, when the gears on the first penetrating rod and the second penetrating rod are engaged with the gear sleeves in the first support frame and the second support frame, the first support frame and the second support frame are limited and fixed. When the first support frame and the second support frame need to be retracted, only the first penetrating rod and the second penetrating rod need to be pushed inward to release the restriction of the first support frame and the second support frame, so the seat body can be retracted. In this process, the first sleeve, the second sleeve and the adjustment mechanism can cooperate with each other to limit and fix the first penetrating rod and the second penetrating rod, thereby improving the practicality of the device.

[0018] 2. By setting an adjustment mechanism, the seat body can be locked and limited by this mechanism. The worm is driven to rotate by the hand-cranked disk in the mechanism, and the first turbine and the second turbine are driven to rotate respectively by the worm, and the first transmission rod is driven to rotate by the first turbine. In this process, the first transmission rod can be limited and supported by the first transverse plate on one side of the first limiting rod, so that one end of the first transmission rod is movably installed in the second sleeve, and then the second penetrating rod is limited and fixed. When the second turbine drives the second transmission rod to move, the second transmission rod can be limited and supported by the second transverse plate on the second limiting side in this process, so that one end of the second transmission rod is movably installed in the first sleeve, so as to limit the first penetrating rod. In this process, the first turbine, the second turbine and the worm can be limited by the first limiting assembly and the second limiting assembly. Because the first limiting rod and the second limiting rod are provided with a sliding ball assembly, when the seat body is retracted, the first hinge and the second hinge can cooperate with each other to make the first limiting rod and the second limiting rod shrink accordingly, thereby improving the working efficiency of the device.

[0019] 3. While designing the above structure, the bottom of the seat body can be used by placing components to facilitate the placement of various items conveniently and quickly. The angle of the backrest can be adjusted through the leaning component. The slide plate and the sliding sleeve in the component cooperate with each other to adjust according to needs. The support plate and the serrated plate cooperate with each other to limit and fix the backrest. This process can be limited by a spring, making the device more convenient and quick to use.

[0039] Working principle: During operation, only the first fixing sleeve 42 in the supporting mechanism 4 is needed to drive the first penetrating rod 43 to move horizontally, and the first supporting frame 41 is limited and retracted. In this process, the first penetrating rod 43 and the second penetrating rod 48 are engaged with the first supporting frame 41 and the second supporting frame 46 at the contact point through the gear sleeve. Therefore, when the gears on the first penetrating rod 43 and the second penetrating rod 48 are engaged with the gear sleeves in the first supporting frame 41 and the second supporting frame 46, the first supporting frame 41 and the second supporting frame 46 are limited and fixed.

During this process, the first limiting assembly 65 and the second limiting assembly 611 cooperate with each other to limit the first turbine 63, the second turbine 69 and the worm 62. Since the first limiting rod 66 and the second limiting rod 612 are provided with a sliding ball assembly, the first hinge 68 and the second hinge 613 cooperate with each other to make the first limiting rod 66 and the second limiting rod 612 shrink when the seat body 1 shrinks.
