Four or three supporting claws can be arranged according to needs, and rubber anti-slip pads are fixedly arranged at the bottom ends of the supporting claws.

[0035] Embodiment 2: The main difference between this embodiment and the first technical solution is: a new type of crutch, the cover plate assembly 49 includes a circular cover plate 491 threadedly connected to the storage tube 41 and an avoidance slot 492 opened on the top of the circular cover plate 491, arc-shaped movable slots 493 are opened on the left and right side walls of the avoidance slot 492, and an arc-shaped slot 494 connected to one of the arc-shaped movable slots 493 is opened on one side of the top of the circular cover plate 491, and a block assembly for controlling the opening and closing of the avoidance slot 492 is arranged inside one of the arc-shaped movable slots 493. The block assembly includes an arc-shaped baffle 495 slidably connected to the arc-shaped movable slot 493, a spring 2 496 is fixedly arranged between the arc-shaped baffle 495 and the inner wall of the arc-shaped movable slot 493, and a push rod is fixedly arranged on the top of the arc-shaped baffle 495 for conveniently pushing the arc-shaped baffle 495 to move. The push rod slides through the arc-shaped slot 494 and extends to the outside. When the arc baffle 495 is not subjected to external force, the two ends of the arc baffle 495 are respectively located in the two arc movable grooves 493, and the width of the avoidance groove 492 is slightly larger than the outer diameter of the handle of the automatic folding umbrella body 7. An external thread groove is provided on the outer wall of the circular cover plate 491, and an internal thread groove is provided on the inner wall of the storage tube 41. The circular cover plate 491 and the storage tube 41 are connected through the external thread groove and the internal thread groove.

[0036] When in use, pedestrians hold handle 1 5 and use the crutch support rod formed by support rod 1 1 , support rod 2 2 and support base 3 to assist walking. They can also flip handle 2 6 downward by 90 degrees and hold handle 1 5 and handle 2 6 with both hands to increase body stability. When it is rainy or the sun is strong, the automatic folding umbrella body 7 needs to be used. The cover assembly 49 is rotated and the cover assembly 49 is removed from the storage tube 41. Since the cover assembly 49 has downward pressure on the automatic folding umbrella body when it is connected to the storage tube 41, the spring 1 47 is compressed. At the moment when the cover assembly 49 is removed, the elastic force of the spring 1 47 pushes the lifting plate 46 to move up a distance along the inner wall of the cylinder 45. When the lifting plate 46 moves up, the umbrella handle positioning tube 48 is pushed upward synchronously. When the umbrella handle positioning tube 48 moves up a certain distance, it is blocked by the U-shaped limit plate 44 and cannot continue to move up. At this time, the top part of the automatic folding umbrella body 7 protrudes out of the storage tube. 41, then, manually pull the automatic folding umbrella body 7 out of the storage tube 41, then stretch and unfold the folding part of the umbrella handle of the automatic folding umbrella body 7, increase the support height of the automatic folding umbrella body 7, and ensure that the person holding crutches can be normally located at the bottom of the umbrella when walking, then, manually push the push rod on the top of the arc-shaped baffle plate 495, and store the arc-shaped push plate 495 into the arc-shaped movable cabinet groove 493, so that the avoidance groove 492 is completely exposed. At this time, the avoidance groove 492 is put on the umbrella handle of the automatic folding umbrella body 7 and the push rod is released. The arc-shaped baffle plate 495 is pushed to reset by the elastic force of the spring 2 496, and the avoidance groove 492 is blocked. Then, the circular cover plate 491 is rotated and threadedly connected with the storage tube 41. When the automatic folding umbrella body 7 needs to be inspected or replaced, with the help of the inspection port 42 and the long strip through groove at the corresponding position, and the position of the fastening bolts set on the side wall of the umbrella handle positioning tube 48 is opposite to the inspection port 42 and the long strip through groove, therefore, after loosening the fastening bolts, the U-shaped limit plate 44 and the cover plate assembly 49 are disassembled, and the automatic folding umbrella body 7 can be separated from the storage tube 41 by pulling it upwards, and a new automatic folding umbrella body 7 of the same type can be replaced for use.
