[0023] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0024] Example 1: As Figures 1 to 5 As shown, this embodiment provides a switching mechanism for a folding cane stool, which has an unfolded state and a folded state, including:

[0025] Support assembly 1 includes a support rod 11 arranged along an axial direction, and an upper latch 111 and a lower latch 112 are provided on the support rod 11.

[0026] The folding assembly 2 includes a positioning seat 21, a sliding seat 22, a folding rod 23, and a fixing seat 24. The positioning seat 21 is sleeved on the support rod 11 and can slide axially on the support rod 11. The sliding seat 22 is axially slidably sleeved on the support rod 11 and located above the positioning seat 21. The fixing seat 24 is fixedly disposed on the support rod 11 and located below the positioning seat 21.

[0027] The foldable stool assembly 3 has its inner end pivotally connected to the sliding seat 22, its outer end pivotally connected to one end of the folding rod 23, and the other end of the folding rod 23 pivotally connected to the fixed seat 24.

[0028] A switching mechanism 4 is provided on the sliding seat 22. The switching mechanism 4 cooperates with the upper bayonet 111 and the lower bayonet 112 to fix the sliding seat 22 at the upper bayonet 111 or the lower bayonet 112.

[0029] The folding cane stool provided in this embodiment has a simple structure and relatively high reliability. Specifically, the sliding seat 22 is effectively fixed by the cooperation of the switch mechanism 4 with the upper latch 111 or the lower latch 112, thereby limiting the cane stool and seat assembly to an unfolded or folded state. Its structural reliability is relatively high. In particular, when the cane stool is in the folded state, the cooperation between the switch mechanism 4 and the upper latch 111 will not be easily triggered to open, thereby improving the reliability and safety of the product.

[0030] In the embodiment, the switch mechanism 4 at least comprises a button 41, a clasp ring 42 and a spring 43, wherein a mounting seat 221 is arranged on the sliding seat 22, an annular seat 222 is arranged in the middle of the mounting seat 221, the clasp ring 42 is sleeved outside the annular seat 222, a notch 2220 is formed on the annular seat 222, a clamping portion 421 is arranged on the clasp ring 42, the clamping portion 421 is movably arranged in the notch 2220 to be inserted into or separated from the upper or lower clamping hole 111 / 112, the button 41 is arranged on the mounting seat 221 and connected with the clasp ring 42, and the spring 43 is arranged in the mounting seat 221 and matched with the clasp ring 42 to provide a reset force for the clasp ring 42. The structure is simple, reasonable and ingenious, and the reliability is relatively high.

[0031] Specifically, in use, the clamping portion 421 is separated from the upper or lower clamping hole 111 / 112 by pressing the button 41 to overcome the elastic force of the spring 43, and then the sliding seat 22 can be moved axially. When the sliding seat 22 is moved to the position of the other clamping hole, the button 41 is released, and at this time the clasp ring 42 is reset under the action of the elastic force of the spring 43, and the clamping portion 421 is inserted into the upper or lower clamping hole 111 / 112, thereby fixing the sliding seat 22. The switch mechanism provided in the embodiment is convenient to use, and the user experience is better. The sliding seat 22 is effectively fixed by the cooperation of the switch mechanism 4 and the upper or lower clamping hole 111 / 112, so that the crutch stool and the seat stool assembly can be limited in the unfolded state or the folded state, and switched between the unfolded state and the folded state. The structural reliability is relatively high, and especially when the crutch stool is in the folded state, the cooperation between the switch mechanism 4 and the upper clamping hole 111 cannot be easily triggered to open, thereby improving the reliability and safety of the product.

[0032] In the embodiment, a connecting portion 422 is protrudingly arranged on the clasp ring 42, and a connecting hole 411 is formed on the button 41, the connecting portion 422 is inserted into the connecting hole 411 to realize the connection between the clasp ring 42 and the button 41. The structure is simple, and the stable and reliable connection between the clasp ring 42 and the button 41 can be realized, thereby improving the stability and reliability of the product in use.

[0033] Further, a plurality of spaced apart boss portions 223 are arranged outside the annular seat 222, the clasp ring 42 is supported on the boss portions 223, and the clasp ring 42 can be translated on the boss portions 223. The structure is simple, and the stability and smoothness of the movement of the clasp ring 42 can be improved, thereby improving the operation experience of the user in use.

[0034] Further, the installation cover 5 is arranged on the top of the mounting seat 221, the button 41, the snap ring 42 and the spring 43 are limited in the mounting seat 221 through the installation cover 5, the structure is simple, the installation cover 5 can be arranged to limit the button 41, the snap ring 42 and the spring 43, and the button 41, the snap ring 42 and the spring 43 can be protected, so that the stability and reliability of the overall structure of the product are improved.

[0035] Further, the installation cover 5 is arranged on the top of the mounting seat 221, the button 41, the snap ring 42 and the spring 43 are limited in the mounting seat 221 through the installation cover 5, the structure is simple, the installation cover 5 can be arranged to limit the button 41, the snap ring 42 and the spring 43, and the button 41, the snap ring 42 and the spring 43 can be protected, so that the stability and reliability of the overall structure of the product are improved.
