Chinese patent CN214910100U discloses a kind of crutch, and discloses a kind of intelligent crutch with high safety performance, including a supporting stick, a control terminal is installed on the supporting stick, the upper end of the supporting stick is fixedly connected to the handrail, the lower end of the supporting stick is fixedly connected to the supporting box, and the middle two ends of the supporting stick are provided with annular air bags installed on the supporting stick and symmetrically distributed, and the annular air bags are connected with the supporting stick. The flexible anti-skid pad is nested and fixedly connected with an air outlet pipe extending into the support box, the air outlet pipe is connected with a gas generator, and the outer side of the gas generator is attached with an annular pressure sensor installed on the inner wall of the extrusion rod. The bottom plate of the support box is slidably connected with a plurality of movable pads, and the movable pads are fixedly connected with the flexible anti-skid pad. A support extrusion mechanism is arranged between the movable pads and the gas generator. The practical new structure is ingenious, and the annular airbag can be automatically and quickly inflated when the user is about to slip, thereby preventing the user from falling and getting injured.

Currently available crutches use springs, cushions, airbags, suction cups, extended armrests, or sleeve-type (retractable) retractable tubes that are embedded in an outer tube and an inner tube to increase safety. Fall detection uses acceleration sensors, pressure sensors, center of gravity sensors, and communication devices to contact relatives to protect the safety of crutch users.

However, no matter how to prevent the traditional one-handed cane, it will still have a far-reaching impact on the user's muscle strain after falling. Increasing the bottom area that contacts the ground is a good way to increase stability, but if the bottom area that contacts the ground is too large, it will affect the walking space of the elderly. If the bottom area that contacts the ground is too small, the lack of balance will cause injuries when the elderly use it alone. Whether it is a two-legged or three-legged cane, there are safety issues in use. In addition to good stability, the base of the cane must also have sufficient suction or friction to make people feel safer when using it.

This creation aims at the shortcomings of the above-mentioned commercial products and proposes the first improvement measure as follows: add a central column in the middle of the four legs of the crutch, and use a suction cup foot with multiple protruding claws at the base, so that it can maintain better stability on flat ground with terrazzo or uneven stone and sand ground.

The multiple suction cup feet of this creative cane can be used more stably by the elders, and the grip is more stable. While the elders are using it, we, the younger generation, can feel more at ease.

Another innovative design of this creation is to add a two-handed crutch with a left and right crutch connection device to increase the bottom area in contact with the ground. The left and right crutch connection device is equipped with an airbag, which can be quickly inflated when tipping forward to ensure the safety of the user.
