[0029] In this case, the second support plate 6 can be turned over and unfolded by the rotating connection between the second support plate 6 and the first support plate 4, and a load-bearing circular table is formed between the first support plate 4 and the second support plate 6, so that the crutch chair can be used as a chair for the user to temporarily rest when in use; by sliding the first support plate 4 and the sliding block 21 downward along the direction of the main support rod 2, the bottom end of the sliding block 21 and the positioning block 22 are clamped together, so that the position of the rear end of the first support plate 4 is fixed, and at the same time the auxiliary plate 5 is held and the front end of the first support plate 4 is lifted upward, so that the first hinge rod 13 and the second hinge rod 14 at the bottom end of the first support plate 4 are cooperated and deflected in angle, so that the first support plate 4 can be supported, and after the second support plate 6 is turned over, the angle of the side support rod 3 is also adjusted synchronously, so that the two side support rods 3 and the main support rod 2 can support the first support plate 4 and the second support plate 6, and the crutch is changed into a chair, which is convenient for the user to temporarily rest, and the limiting frame 16 arranged outside the main support rod 2 and the side support rod 3 can limit the height at which the main support rod 2 and the side support rod 3 intersect, and the limiting block 15 arranged outside the main support rod 2 and the side support rod 3 can limit the height of the limiting frame 16, avoiding the situation that the limiting frame 16 falls off and causes the main support rod 2 and the side support rod 3 to become loose, and through the cooperation between the first clamping block 17 and the second clamping block 18, the main support rod 2 and the side support rod 3 are also limited and clamped by the first clamping block 17 and the second clamping block 18, so that the position of the limiting frame 16 can be more stably limited, thereby effectively preventing the support part of the whole crutch chair from being excessively opened; when the first support plate 4 is slidingly adjusted in angle, the sliding rail 11 and the sliding block 12 at the bottom end of the first support plate 4 can make the movement and angular deflection of the first hinge rod 13 more smooth, increase the stability of the whole in use, and through the angular rotation adjustment between the first hinge rod 13 and the second hinge rod 14, the first support plate 4, the first hinge rod 13 and the second hinge rod 14 form a triangle, so that the practicability of the whole is increased.

[0030] Embodiment two: as Figure 1 , Figure 2 , Figure 3 and Figure 5The technical scheme shown, in order to solve the problem of weak anti-skid performance of the bottom end of the walking stick chair when used as a walking stick: the high-stability folding portable walking stick chair discloses a wear-resistant mechanism, the bottom end of the side support rod 3 is provided with a fixed block 10, and the bottom end of the main support rod 2 is provided with a wear-resistant mechanism for increasing friction, the wear-resistant mechanism includes a wear-resistant base 7, and the top end of the wear-resistant base 7 is provided with a receiving groove 8 matched with the fixed block 10, the bottom end of the wear-resistant base 7 is provided with an anti-skid protrusion 9, the top view of the main support rod 2 and the side support rod 3 is a flat circle, the cross section of the anti-skid protrusion 9 is a sector, and the anti-skid protrusions 9 are evenly distributed at the bottom end of the wear-resistant base 7, and the edges of the anti-skid protrusions 9 are provided with chamfers.

[0031] In this example, when the walking stick chair is used as a walking stick, the wear-resistant base 7 can increase the contact area between the bottom end of the walking stick and the ground, thereby increasing the stability of the walking stick when in use, and the anti-skid protrusions 9 arranged at the bottom end of the wear-resistant base 7 can increase the friction when the wear-resistant base 7 contacts the ground, thereby increasing the wear-resistant performance of the wear-resistant base 7 and the anti-skid performance of the wear-resistant base 7, thereby making the walking stick more stable when supporting the user, and when used as a walking stick, the receiving groove 8 and the fixed block 10 are mutually engaged, effectively avoiding the angle deflection of the side support rod 3 when supporting, thereby increasing the stability in use; the anti-skid protrusions 9 are arranged in a sector shape, and the edges of the anti-skid protrusions 9 are provided with chamfers, which can increase the contact area between the anti-skid protrusions 9 and the ground, thereby ensuring better wear-resistant and anti-skid performance.
