Then the rear push handle 29 and the front push handle 35 can be released at the same time. After the rear hinged shaft 25 loses the push of the rear push handle 29, the rear end of the rear hinged shaft 25 will be elastically popped into the upper rear rotating hole 21 under the elastic action of the rear spring 27. After the front hinged shaft 31 loses the push of the front push handle 35, the front end of the front hinged shaft 31 will be elastically popped into the upper front rotating hole 22 under the elastic action of the front spring 33. At this moment, the hinged seat 13 and the load-bearing plate 10 are hinged through the front hinged shaft 31 and the rear hinged shaft 25.
[0042] When the hinge seat 13 is hinged with the load-bearing plate 10, the boss 14 on the upper surface of the hinge seat 13 protrudes upward outside the sliding hole 12, the left-hand support plate 15 and the right-hand support plate 16 are both above the load-bearing plate 10, and the left-hand support plate 15 and the right-hand support plate 16 are both hinged with the load-bearing plate 10. The left-hand support plate 15 can rotate leftward around its own hinge point, and finally, under the restriction of the upper surface of the load-bearing plate 10, it is in a flat and unfolded state. The right-hand support plate 16 can rotate rightward around its own hinge point, and finally, under the restriction of the upper surface of the load-bearing plate 10, it is in a flat and unfolded state. At this time, the upper surface of the left-hand support plate 15 is coplanar with the upper surface of the right-hand support plate 16, and the upper surface of the boss 14 can be lower than the upper surface of the left-hand support plate 15 and the upper surface of the right-hand support plate 16, or can be coplanar with the upper surface of the left-hand support plate 15 and the upper surface of the right-hand support plate 16. With the left-hand support plate 15 unfolding flatly to the left and the right-hand support plate 16 unfolding flatly to the right, the left-hand support plate 15 and the right-hand support plate 16 will be combined to form a seat cushion, which can be used by the user to sit on.
[0043] When the hand support mechanism is changed into the shape of a seat cushion, the armpit support mechanism can be changed into the shape of a backrest. When changing the shape, the left backrest plate 42 can be directly held and pulled to the left. At this time, the upper end of the upper support column 1 moves out to the outside of the left rear positioning slot 46, the second left rear segment 5302 of the second left unfolding arm 53 moves out to the outside of the left front clamping gap 38, and the first left unfolding arm 51 and the second left unfolding arm 53 can freely unfold. The left backrest plate 42 is hinged with the central shaft 36 through the first left unfolding arm 51 and the second left unfolding arm 53. Therefore, when the left backrest plate 42 moves to the left, the first left unfolding arm 51 will rotate around the central shaft 36, and the second left unfolding arm 53 will rotate around the position where it is hinged with the first left unfolding arm 51. Under the action of the first left unfolding arm 51 and the second left unfolding arm 53, the left front positioning slot 49 at the front end of the left backrest plate 42 finally moves to the left front position of the upper end of the upper support column 1, and the left front position of the upper end of the upper support column 1 is embedded in the left front positioning slot 49. At this time, the original left side wall of the left backrest plate 42 faces forward, the left chamber 44 of the left backrest plate 42 faces backward, the first left unfolding arm 51 is clamped in the left swinging slot 57, the distance between the first connecting pin 52 on the upper surface of the first left unfolding arm 51 and the second connecting pin 55 on the upper surface of the second left unfolding arm 53 becomes larger, and the left tension spring 56 is stretched and generates elasticity. This elasticity will pull the left backrest plate 42 to the right.
[0044] Then the right backrest 43 can be held and pulled to the right, at this time the upper support column 1 upper end moves out to the right rear positioning slot 47, the second right rear section 5902 of the second right unfolding arm 59 moves out to the right front clamping gap 39, the first right unfolding arm 4001 and the second right unfolding arm 59 can be freely unfolded, and the right backrest 43 is hinged to the central shaft 36 through the first right unfolding arm 4001 and the second right unfolding arm 59, so when the right backrest 43 moves to the right, the first right unfolding arm 4001 will rotate around the central shaft 36, under the action of the first right unfolding arm 4001 and the second right unfolding arm 59, the right front positioning slot 50 at the front end of the right backrest 43 finally moves to the right front position of the upper support column 1 upper end, and the right front position of the upper support column 1 upper end is embedded in the right front positioning slot 50, at this time the original right side wall of the right backrest 43 faces forward, the right cavity 45 of the right backrest 43 faces backward, the first right unfolding arm 4001 is clamped in the right swing slot 63, the distance between the third connecting pin 58 on the lower surface of the first right unfolding arm 4001 and the fourth connecting pin 61 on the lower surface of the second right unfolding arm 59 becomes larger, the right tension spring 62 is stretched and generates elasticity, and this elasticity will pull the right backrest 43 to the left, at this time the original front end face of the left backrest 42 faces right and is pressed on the original front end face of the right backrest 43 under the elastic action of the left tension spring 56, and the original front end face of the right backrest 43 faces left and is pressed on the original front end face of the left backrest 42 under the elastic action of the right tension spring 62, so that the positions of the left backrest 42 and the right backrest 43 are limited and fixed, and the left backrest 42 and the right backrest 43 are combined to form a backrest for the user to lean back.
[0045] As can be seen from the above, when walking is needed, the crutch form can be used to assist walking, and if tiredness is felt during walking, the crutch can be converted into the form of a seat for the user to sit and rest, the user can select between the two forms according to actual needs, the crutch is multifunctional, can meet the actual needs of life, effectively improves convenience, and effectively avoids the situation that tiredness during walking still needs to be rested after reaching the destination, thereby avoiding the situation that walking with a strong and tired body leads to accidents.
