[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 , Figure 2 , Figure 3As shown, the utility model provides a technical solution: a crutch with adjustable height and angle, comprising a crutch body 1 and a stabilizing component, the stabilizing component is arranged inside the crutch body 1, and the stabilizing component is used to achieve the stabilizing effect of the crutch body 1; the stabilizing component comprises a round cover 6, a round groove 7 is opened inside the round cover 6, a corrugated sleeve 8 is fixedly connected to the bottom of the round cover 6, a bottom plate 9 is fixedly connected to the bottom of the corrugated sleeve 8, a fixing column 10 is fixedly connected to the middle of the top of the bottom plate 9, a round ball 11 is fixedly connected to the top of the fixing column 10, the top of the round ball 11 extends to the inside of the round groove 7 and is rotatably connected to the round groove 7, and a reset spring 12 is symmetrically fixedly connected between the bottom of the round cover 6 and the top of the bottom plate 9.

[0021] In this embodiment, the crutch body 1 is made of aluminum alloy as a whole. When the bottom of the crutch body 1 contacts the inclined ground, the rotation cooperation of the ball 11 and the circular groove 7 can ensure that the bottom of the crutch body 1 is always parallel to the ground. Even on uneven or inclined ground, it can maintain good contact and provide more reliable support, which can effectively reduce the shaking and imbalance caused by the uneven ground when the user is walking. At the same time, the reset spring 12 and the corrugated sleeve 8 can provide a certain buffering and shock absorption effect during use, reducing the pressure on the user's hands.

[0022] Example 2

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, three bottom columns 13 are evenly fixedly connected to the bottom of the bottom plate 9, and screws 14 are fixedly connected to the bottom of the bottom columns 13. Support pads 15 are arranged at the bottom of the screws 14. Thread grooves 16 are arranged inside the support pads 15. The screws 14 extend into the inside of the thread grooves 16 and are threadedly connected with the thread grooves 16. The support pads 15 can be disassembled and replaced through the cooperation between the screws 14 and the thread grooves 16. The replaceability of the support pads 15 increases the durability of the entire crutch. The user can regularly replace the support pads 15 as needed to keep the bottom of the crutch in good condition and extend the service life of the crutch.

[0024] A support column 4 is fixedly connected to the top of the round cover 6, and a sleeve 2 is slidably connected to the outer periphery of the support column 4. Through holes 3 are equidistantly provided on one side of the sleeve 2. A spring buckle 5 is provided on one side of the top of the support column 4. The spring buckle 5 passes through the through holes 3, and the spring buckle 5 is snap-fitted with any through hole 3. Through the snap-fitting connection between the spring buckle 5 and the through hole 3, the user can flexibly adjust the height of the support column 4 to meet the needs of different heights or usage scenarios.

[0025] An armrest 17 is fixedly connected to the top of the sleeve 2. An arc-shaped structure is provided on the top of the armrest 17. Anti-slip layers are provided on the armrest 17 and the support pad 15. The arc-shaped structure of the armrest 17 can better adapt to the curve of the hand and provide a more comfortable holding experience. Moreover, the anti-slip layers on the armrest 17 and the support pad 15 can increase the friction between the hand and the bottom of the crutch, improve stability, prevent the hand from sliding, and maintain the safety of the user. The elastic force of the return spring 12 is greater than the elastic force of the corrugated sleeve 8, which means that when the support pad 15 is compressed, the return spring 12 can restore it to its original position more strongly, thereby ensuring that the bottom of the crutch always remains stable and balanced.
