[0042] Specifically, since the foot pipe 6 is folded, the elastic limiting structure 5 is separated from the folding structure. Therefore, the folding rod 13 can be turned by 90 degrees in the rotating slot 12 through the rotating block 131. When it contacts the ground, it can be used as a supporting foot, so it remains stable and is not easy to fall.

[0043] Working principle:

[0044] When using two medical crutches, according to the height of the patient, the first medical crutch foot pad 62 is grasped and rotated to drive the threaded rod 61 to rotate and extend into the inner threaded slot of the foot pipe 6, thereby adjusting the height of the medical crutch, so that the armpit support 2 on the crutch main body 1 can contact the patient's armpit. Then, according to the length of the patient's arm, the hand holding structure 4 is installed on the appropriate set of adjustment holes 11. The adjustment bolt 43 is rotated and separated from the handle 42. The handle 42 is grasped and the latch 44 is inserted into one of the adjustment holes 11. Then, the adjustment bolt 43 is threaded through the parallel adjustment hole 11 and threaded with the handle 42 to achieve limiting installation. The second medical crutch is operated in the same way. The patient grasps the two medical crutch handles 42 and brings the crutch main body 1 into the armpit. The foot pad 62 on the foot pipe 6 contacts the ground. Through the support of the two medical crutches with the arms back and forth, the patient can move. During the use of the medical crutch, the armpit support 2 is made of TPR material and is relatively comfortable in contact with the armpit under stress. In addition, the armpit support 2 has a through slot 21 opened in the middle. During the stress process, the through slot 21 is squeezed and deformed, having a certain buffering effect, further improving comfort.

[0045] When folding and carrying two medical crutches, as Figure 7As shown, the first medical crutch hand grip structure 4 is adjusted to the middle position of the multiple sets of adjusting holes 11, the flip cover 46 is opened by holding the buckle groove 461, the limiting groove 45 is leaked, then the limiting sleeve 51 is held and forced downward to extrude and shrink the limiting spring 52, the limiting sleeve 51 is separated from the two folding structures, the user holds the foot pipe 6 and flips it upward to combine with the crutch body 1, the foot pad 62 is embedded in the limiting groove 45 to limit, the second medical crutch is operated in the same way, finally the blocking plate 35 of the first medical crutch is held and pulled out to drive the support cloth 34 to rotate the connecting shaft 32 to unwind, the volute spring 33 is shrunk to store energy, the two elastic telescopic structures 36 are pressed to shrink, the two telescopic blocks 363 are forced to shrink into the telescopic grooves 361 to extrude the telescopic springs 362, so that the blocking plate 35 can be inserted into the through groove 21 of the second medical crutch, then the fingers are inserted into the through groove 21 to push the blocking plate 35 through the through groove 21, the telescopic spring 362 rebounds to drive the telescopic block 363 to stretch out, limiting the blocking plate 35 through the through groove 21, at the same time, the volute spring 33 rebounds to drive the connecting shaft 32 to wind the support cloth 34, the two folding medical crutches are connected together, this folding way is not only convenient to carry, but also not easy to lose single medical crutch;

[0046] Two medical crutches are used as temporary rest stools, such as Figure 8As shown, the first medical crutch hand grip structure 4 is adjusted to the lowermost position of the multiple sets of adjustment holes 11, and then the buckle slot 461 is grabbed to open the flip cover 46 and release the limiting slot 45. Then the limiting sleeve 51 is grabbed and forced downward to compress the limiting spring 52 and store energy, and the limiting sleeve 51 is disengaged from the two folding structures. Thus, the foot tube 6 can be freely flipped, and the elastic limiting structure 5 of the second medical crutch is operated in the same way, so that it can be flipped upward with the foot tube 6, and the foot pad 62 is grabbed and rotated to drive the threaded rod 61 to rotate and extend out of the internal threaded groove of the foot tube 6. During the upward flipping process of the foot tube 6, the foot pad 62 can be embedded in the limiting slot 45 of the first medical crutch hand grip structure 4 for limiting. Then the foot tube 6 of the first medical crutch is flipped upward, so that part of it is exposed to the threaded rod 61, which can be inserted between the two tube bodies at the bottom of the crutch body 1 of the second medical crutch, and the foot pad 62 is rotated to drive the threaded rod 61 to retract, so that the foot pad 62 is in contact with the bottom of the second medical crutch for limiting. Then the blocking plate 35 is grabbed and pulled out to drive the support cloth 34 to rotate and unwind, drive the spiral spring 33 to retract and store energy, and the support cloth 34 surrounds the armpit support 2 of the first and second crutches. The two elastic extension structures 36 are pressed and retracted from the outside of the through slot 21 of the second medical crutch, and then the fingers are inserted into the through slot 21 to push the blocking plate 35 through the through slot 21. The extension spring 362 rebounds to drive the extension block 363 to extend, limiting the blocking plate 35 passing through the through slot 21. At this time, the connecting shaft 32 is completely unwound and connected with the support cloth 34. Since the foot tube 6 is flipped, the four folding structures of the two medical crutches are not limited, so the folding rod 13 can be flipped by ninety degrees in the rotating slot 12 through the rotating block 131, and can be used as a supporting foot when contacting the ground, so that it remains stable and is not easy to fall. After the two medical crutches are folded and combined into a stool, the user can sit on the stretched support cloth 34, which drives the two medical crutches to bear force. The two medical crutches are kept completely stretched through the inclined foot tube 6, and are connected and limited by the transverse foot tube 6, so that they can still maintain stability and are not easy to collapse when bearing force.
