[0031] The cane foot 3 has several grooves 31 on its side. The support rod 6 has a fixing buckle 61 on the side near the round rod 2. When the support rod 6 is open, the fixing buckle 61 is inserted into the corresponding groove 31 and a sufficient gap is maintained. When the support rod 6 is closed, the clamping member 4 clamps and fixes the support rod 6.

[0032] It should be noted that when the device is supported by one leg, the support structure is the cane leg 3, and when it is supported by multiple legs, the support structure is the auxiliary leg 62 of the support rod 6.

[0033] It should be further explained that the spring 9 not only ensures the stability of the cane foot 3 and the support rod 6, but also provides a good rebound and cushioning effect for the cane foot 3 when supporting one foot, ensuring the user's comfort.

[0034] It should also be noted that when switching from single-leg to multi-leg use, the height of the cane will increase. At this time, the height of the round bar 2 on the cane can be adjusted using the existing telescopic technology to facilitate the patient's use.

[0035] In this embodiment, a fixing ring 7 is provided at the connection between the handle 1 and the round rod 2, and the handle 1 and the round rod 2 are connected by a fitting relationship of sleeve or plug.

[0036] It should be noted that the fixing ring 7 can enhance the stability of the connection between the handle 1 and the round rod 2. At the same time, the fit between the handle 1 and the round rod 2 facilitates the replacement of the handle 1 in the future, making the cane customizable.

[0037] In this embodiment, a protrusion 32 is fixedly installed on the top of the cane foot 3, and a groove 8 is provided at the bottom of the round rod 2. The top of the protrusion 32 of the cane foot 3 is located in the groove 8 on the round rod 2.

[0038] In this embodiment, the side of the protrusion 32 is inverted convex, the side of the second groove 8 is inverted convex, the upper end of the protrusion 32 is engaged inside the second groove 8, and the spring 9 is located inside the second groove 8 and at the top of the protrusion 32.

[0039] It should be noted that the protrusion 32 and the groove 8 not only ensure the extension and sliding of the cane foot 3 and the round rod 2, but also enable the cane foot 3 to engage with the round rod 2 after it has been extended to a certain length.

[0040] In this embodiment, all support rods 6 are arranged in a circular array about the axis of the round rod 2, and the distance between any two adjacent support rods 6 is equal.

[0041] It should be noted that each support rod 6 provides support when it is opened, and the pressure on each support rod 6 is the same. This distribution of support rods 6 can evenly distribute the pressure on each support rod 6 and improve the service life of the support rods 6.

[0042] In this embodiment, the round rod 2 is a hollow circular structure located at the upper end of the spring 9, and the support rod 6 is a hollow circular structure.

[0043] It should be noted that the hollow structure was designed to reduce the weight of the device and make it easier for users to operate.

[0044] In this embodiment, the parts of the round rod 2, the support rod 6, and the cane foot 3 with the groove 31 are all made of high-strength alloy materials, such as aluminum alloy. The auxiliary foot 62 and the bottom of the cane foot 3 are all made of rubber material, and the clamping part 4 is made of flexible plastic.

[0045] It should be noted that aluminum alloy not only has anti-oxidation function, but also has the advantages of high hardness and light weight, making it more convenient for patients to use. At the same time, the clamping part 4 is a traditional plastic structure for clamping round pipes on the market, which makes it convenient to clamp the support rod 6.

[0046] It should be further noted that the auxiliary foot 62 should be fixed at a certain angle to the support rod 6 to ensure that the auxiliary foot 62 is perpendicular to the ground when the support rod 6 is opened and fixed.

[0047] In this embodiment, the fixing buckle 61 is arc-shaped. When the support rod 6 is opened, one side of the fixing buckle 61 cooperates with the groove 31, and the other side is fixedly installed on the support rod 6.

[0048] It should be noted that the support rod 6 is rotated and fixed by the cooperation between the fixing buckle 61 and the groove 31 fixedly installed on the support rod 6. At the same time, due to the telescopic nature of the cane foot 3, it is convenient to switch between the fixed and unfixed state of the support rod 6, and the switching between multi-leg and single-leg is more convenient and quick.

[0049] In this embodiment, the angle between the support rod 6 and the round rod 2 when the rod is open is between 30° and 60°.

[0050] It should be noted that the angle between the support rod 6 and the round rod 2 when the support rod is open should not be too large, so as to prevent the fixed buckle 61 from breaking due to the increased force caused by the large angle. At the same time, the angle should not be too low, so as to ensure the stability of all support rods 6 when they are in contact with the ground when they are open.

[0051] In summary, this adjustable medical cane, when used with multi-leg support, utilizes at least three support rods 6 rotatably mounted at the bottom of the round rod 2 to transform the device from a single-leg cane to a multi-leg cane. The locking buckles 61 and grooves 31 work together to secure the open support rods 6. Specifically, the support rods 6 are first opened, then the cane feet 3 are pressed close to the round rod 2, then the support rods 6 are rotated to be directly below the grooves 31, and finally the cane feet 3 are released. This allows the grooves 31 on the cane feet 3 to engage with the locking buckles 61 on the corresponding support rods 6. Due to the special arc design of the locking buckles 61, the support rods 6 are difficult to rotate further, thus completing the rotational fixation of the support rods 6.

[0052] This medical adjustable cane allows for single-leg support. By rotating the support rod 6, it engages with the clamping part 4 to retract the support rod 6 without disturbing the user. The cane foot 3 provides additional support, making single-leg support more convenient. The cane foot 3 not only serves as a support for single-leg use but also secures the support rod 6 with the spring 9 when used with multiple legs. The ingenious structure allows for switching between single-leg and multi-leg modes, enhancing usability.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
