[0018] In order to make the present invention clearer and more understandable, the technical solution of the present invention is further described in detail below in combination with the accompanying drawings and embodiments. It should be understood that the given embodiment is only one of the implementation methods and does not represent all embodiments.

[0019] In this article, terms such as "inside, outside, up, and down" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. Therefore, they cannot be understood as absolute limitations on the scope of protection.

[0020] Combined with attachment Figure 1 -Attached Figure 4 A multifunctional crutch comprises a crutch rod 1 with a handle at the top, the crutch rod 1 is provided with multiple groups of hanging mechanisms 2, and the multiple groups of hanging mechanisms 2 are arranged at intervals along the length direction of the crutch, the bottom of the crutch rod 1 is connected to the support wheel 3 through a folding mechanism 4, the folding mechanism 4 comprises a first slip ring 5, a first connecting rod 6, a support plate 7 and a lifting drive mechanism for driving the first slip ring 5 to rise and fall, the first slip ring 5 is arranged on the outer wall of the crutch rod 1 through the lifting drive mechanism, one end of the support plate 7 is hinged to the crutch rod 1, the support plate 7 is located below the first slip ring 5, there are four support plates 7, and the four support plates 7 are evenly arranged along the circumference of the crutch rod 1, one end of the first connecting rod 6 is hinged to the first slip ring 5, and the other end of the first connecting rod 6 is hinged to the top of the support plate 7, and the support wheel 3 is rotatably set at the bottom of the support plate 7.

[0021] Under normal conditions, the top of the support plate 7 is close to the crutch rod 1, and the support wheel 3 is in a folded state. At this time, the bottom of the crutch rod 1 is the part that contacts the ground. When the support wheel 3 needs to be unfolded, the first slip ring 5 is driven downward by the lifting drive mechanism, and the first slip ring 5 drives the support plate 7 to rotate through the first connecting rod 6. The support plate 7 rotates away from the crutch rod 1 until the bottom cross-section of the support wheel 3 is in a horizontal plane. At this time, the bottom of the support wheel 3 is located below the bottom of the crutch. At this time, the support wheel 3 is the part that contacts the ground. When the folding wheel needs to be folded, the first slip ring 5 is driven upward by the lifting drive mechanism.

[0022] Specifically, a support pad 16 is fixed to the bottom end of the crutch rod 1, and the support pad 16 can be made of rubber.

[0023] Specifically, the lifting drive mechanism includes a rotating drum 9, which is sleeved on the outer wall of the crutch shaft 1 and rotatably connected to the crutch shaft 1. The outer wall of the rotating drum 9 is provided with an external thread, and the inner wall of the first slip ring 5 is provided with an internal thread that matches the external thread. The first slip ring 5 is threadedly connected to the outer wall of the rotating drum 9 through the mating of the external and internal threads. When the first slip ring 5 needs to be driven to move, the rotating drum 9 is rotated forward or reversed, and the first slip ring 5 can move up or down along the rotating drum 9 under the cooperation of the internal and external threads.

[0024] Specifically, a hand-held cylinder 10 is coaxially fixed to the top of the rotating drum 9. The outer diameter of the hand-held cylinder 10 is larger than the inner diameter of the first slip ring 5, and the outer wall of the hand-held cylinder 10 is provided with anti-slip grooves. The hand-held cylinder 10 can limit the first slip ring 5, preventing the first slip ring 5 from detaching from the rotating drum 9 from the top of the rotating drum 9, and the hand-held cylinder 10 facilitates the user to rotate the rotating drum 9.

[0025] Specifically, a mounting plate 8 is provided on both sides of the support plate 7 away from one end of the crutch rod 1. The two mounting plates 8 are symmetrically arranged, and one end of the mounting plate 8 extends to the bottom of the support plate 7. The support wheel 3 is located between the two mounting plates 8 and is rotatably connected to the extended ends of the two mounting plates 8.

[0026] Specifically, the hanging mechanism 2 includes a second sliding ring 11, a second connecting rod 12, a hanging rod 13, a return spring 14 and a fixed ring 15. The fixed ring 15 is sleeved on the outer wall of the crutch rod 1 and fixedly connected to the crutch rod 1. The second sliding ring 11 is sleeved on the outer wall of the crutch rod 1 and slidingly connected to the crutch rod 1. One end of the hanging rod 13 is hinged to the fixed ring 15, one end of the second connecting rod 12 is hinged to the top of the hanging rod 13, and the other end of the second connecting rod 12 is hinged to the second sliding ring 11. The return spring 14 is sleeved on the outer wall of the crutch rod 1, the top of the return spring 14 is fixedly connected to the second sliding ring 11, and the bottom end of the return spring 14 is fixedly connected to the fixed ring 15.

[0027] When no item is hung, the top of the hanging rod 13 is close to the crutch shaft 1, the hanging rod 13 is in a retracted state, and the return spring 14 is in a natural state. During use, an item is placed between the second connecting rod 12 and the hanging rod 13. Under the weight of the item, the hanging rod 13 rotates away from the crutch shaft 1, and the item drives the hanging rod 13 to unfold. At this time, the hanging rod 13 drives the second sliding ring 11 downward through the second connecting rod 12. The second sliding ring 11 compresses the return spring 14, which generates an upward elastic force, balancing the weight of the item and allowing the item to be hung on the hanging rod 13. After the item is removed, the return spring 14 loses pressure and returns to its original state, driving the second sliding ring 11 upward. The second sliding ring 11 drives the hanging rod 13 to rotate through the second connecting rod 12, and the hanging rod 13 is retracted.

[0028] Specifically, each set of the hanging mechanism 2 includes two hanging rods 13, which are symmetrically arranged. Each hanging rod 13 is connected to the second sliding ring 11 through a second connecting rod 12. The two symmetrical hanging rods 13 allow items to be hung on the two hanging rods 13 respectively, thereby improving the balance of the crutch after hanging the items.

[0029] Specifically, a plurality of anti-slip protrusions are provided on the top of the hanging rod 13, and the plurality of anti-slip protrusions are arranged along the length direction of the hanging rod 13. The anti-slip protrusions can increase the friction between the items and the hanging rod 13, and prevent the items from sliding off the hanging rod 13 after being hung.

[0030] Although embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
