[0041] The crutch chair provided by the embodiment needs to be unfolded when the chair is used. The pressing part 304 of the pressing switch 3 is pressed to drive the sliding part 303 to move into the switch body 301, the spring A 305 is compressed under force, the sliding part 303 drives the locking part 306 to move away from the locking hole 203 of the main support rod 2, the linkage rod 601 is pulled downward by the main spring 602 due to the pulling force, the linkage rod 601 drives the pressing switch 3 to move downward along the main support rod 2 through the clamping block A 603, the clamping block D 606 first moves away from the bottom of the clamping block 701, the clamping block 701 moves downward under the elastic force of the spring B 703, the clamping groove 704 of the clamping block 701 moves away from the auxiliary clamping hook 409 of the auxiliary chair surface 404, and the main clamping hook 705 moves away from the hinged column 408 of the main chair surface 403. At this time, the chair surface locking structure 7 is unlocked. After unlocking, the clamping block B 604 is in contact with the upper end of the upper sliding part 402 and pushes the upper sliding part 402 to move downward along the main support rod 2, the clamping block E 607 is in contact with the upper end of the lower sliding part 502 and pushes the lower sliding part 502 to move downward along the main support rod 2, the upper sliding part 402 moves to drive the main chair surface support rod 405 to unfold, the main chair surface support rod 405 drives the auxiliary chair surface support rod 406 to unfold, and the whole chair surface is gradually unfolded. After the upper sliding part 402 moves to the top of the lower fixing part 501, the positioning pin 407 is clamped into the positioning hole 505 and fixed; the lower sliding part 502 moves to drive the connecting rod A 506, the connecting rod B 507, the connecting rod C 508 and the connecting rod D 509 to unfold, and drives the support rod A 510 and the support rod B 511 to overturn downward, the support rod C 512 and the support rod D 513 move downward to unfold. After unfolding, the support rod A 510 and the support rod C 512 are in a straight line structure, and the support rod B 511 and the support rod D 513 are in a straight line structure. After unfolding, the pressing switch 3 moves to the lower end of the locking hole 203, the locking part 306 is popped out into the locking hole 203 under the action of the spring A 305, and the unfolded state is locked. After unfolding, the chair can be used (the locking hole 203 does not have a locking effect, and is not easy to be pulled upward under the pulling force of the main spring 602).

[0042] The crutch chair provided by the embodiment needs to be folded when the crutch is used. The pressing piece 304 of the pressing switch 3 is pressed to disengage the locking portion 306 from the locking hole 203 of the main support rod 2. Then the pressing switch 3 is pulled upward by hand. The pressing switch 3 drives the clamping block A 603 of the linkage rod 601 to move upward. The clamping block C 605 contacts the lower end of the upper sliding piece 402 and drives the upper sliding piece 402 to move upward along the main support rod 2. The upper sliding piece 402 drives the main support rod 405 and the auxiliary support rod 406 of the seat surface to be folded, so that the folding of the seat surface is realized. The clamping block F 608 contacts the lower end of the lower sliding piece 502 and drives the lower sliding piece 502 to move upward along the main support rod 2. The movement of the lower sliding piece 502 drives the connection rod A 506, the connection rod B 507, the connection rod C 508 and the connection rod D 509 to be folded, and drives the support rod A 510 and the support rod B 511 to be flipped upward and close to the main support rod 2.
