Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Combination Figures 1 to 8 A guide cane with adjustable length includes a handle 1, a cane body 2 fixedly connected to the bottom of the handle 1, a cane body 3 movably connected inside the cane body 2, a stabilizing mechanism 5 provided at the bottom of the cane body 3, and an adjusting mechanism 4 provided inside the cane body 3.

[0031] The adjustment mechanism 4 includes a fixed cylinder 41, which is fixedly connected to the inner wall of the second cane body 3. A spring 42 is fixedly connected to the inner wall of the second cane body 3. A circular plate 43 is fixedly connected to the end of the spring 42 away from the inner wall of the second cane body 3. A pressure column 44 is fixedly connected to the side of the circular plate 43 away from the spring 42. A fastening nut 45 is provided on the outer wall of the first cane body 2.

[0032] Furthermore, ten positioning holes are provided on the outer wall of the cane body 2, and the pressure column 44 is movably connected to one of the inner walls. A through hole is provided on the outer wall of the cane body 2, and the pressure column 44 passes through the through hole to facilitate positioning of the pressure column 44.

[0033] Furthermore, the inner wall shape of the fixed cylinder 41 matches the outer shape of the circular plate 43, and the circular plate 43 is slidably connected to the inner wall of the fixed cylinder 41, so that the circular plate 43 can stably slide to compress the spring 42.

[0034] Furthermore, the outer wall of the cane body 2 is provided with threaded patterns that match the inner wall of the fastening nut 45. The fastening nut 45 is threadedly connected to the outer wall of the cane body 2 through the threaded patterns, thereby achieving the purpose of stable positioning.

[0035] Example 2

[0036] See Figures 1 to 8 Furthermore, based on Embodiment 1, the stabilizing mechanism 5 includes a threaded head 51, which is disposed on the inner wall of the second cane body 3. A base 53 is fixedly connected to the bottom end of the threaded head 51, a sealing sleeve 52 is fixedly connected to the top of the base 53, and a sealing ring 54 is fixedly connected to the outer wall of the second cane body 3, so as to facilitate the disassembly and replacement of the base 53.

[0037] Furthermore, the outer wall of the threaded head 51 and the inner wall of the second rod body 3 are provided with matching thread patterns. The threaded head 51 is threadedly connected to the inner wall of the second rod body 3 to achieve the purpose of connecting and installing the base 53.

[0038] Furthermore, the sealing sleeve 52 is movably connected to the outer wall of the rod body 2 3, and the top of the sealing sleeve 52 contacts the bottom of the sealing ring 54, extending the service life of the device connection and installation.

[0039] In actual operation, when this device is in use, the base 53 can be turned to unscrew the threaded head 51 from the inner wall of the second rod body 3, thereby disassembling the base 53. This allows different users to replace different types of bases 53 according to different usage scenarios and habits. At the same time, the top of the sealing sleeve 52 can abut against the bottom of the sealing ring 54, thereby protecting the connection between the threaded head 51 and the second rod body 3, reducing damage to the threaded texture, and extending the service life of the device.

[0040] During use, when the overall length needs to be adjusted, the fastening nut 45 can be turned first. Since the fastening nut 45 and the cane body 2 are threadedly connected, and the bottom end of the cane body 2 has equidistant elongated openings, these openings form an elastic strip. When the strip is located on the inner wall of the cylinder of the fastening nut 45, it will press the strip, clamping and limiting the cane body 2. Under the action of the threads on the outer wall of the cane body 2, the fastening nut 45 will move upward. At this time, the strip will deform and burst open. The shape of the bursting open is exactly the conical shape of the bottom end of the fastening nut 45, thus releasing the clamping and limiting effect on the cane body 2. When the limit on the second cane body 3 is removed, the pressure column 44 can be pressed, so that the pressure column 44 can push the circular plate 43 to slide on the inner wall of the fixed cylinder 41 and compress the spring 42. When the pressure column 44 is not located on the inner wall of the positioning hole opened in the first cane body 2, the limit on the second cane body 3 is completely removed, so the second cane body 3 can be pulled down, so that the second cane body 3 can slide out from the inner wall of the first cane body 2 to achieve the purpose of length adjustment. When the appropriate length is adjusted, the pressure column 44 will be inserted into the inner wall of the positioning hole, and the fastening nut 45 will be turned down to move downward, so that the fastening nut 45 presses and limits the long strip. The long strip can play the role of fastening and limiting the second cane body 3.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
