[0003] In the field of tourism and mountaineering equipment, trekking poles are an important auxiliary tool for outdoor travel. They provide support for users, save energy, and are suitable for walking needs in different terrains. Adjustable trekking poles have become the mainstream choice in the market because they can flexibly adjust the length of the pole according to the user's height and usage scenario.

[0004] However, existing adjustable-length hiking sticks mostly use a common pin-type design for their length adjustment limit structure. During outdoor use, after repeated impacts with the ground, the pin is prone to loosening, making it difficult to maintain a stable length limit and affecting safety. Furthermore, some sticks lack a dedicated anti-bending structure inside the stick, making them prone to bending and damage when subjected to external pressure. Therefore, this paper proposes an adjustable-length hiking stick for tourism. Summary of the Invention

[0019] The limiting mechanism includes a box body 2, which is fixedly connected to the outside of the upper tube body 1. The box body 2 has two second sliding grooves 25 inside, each containing a slider 24. A moving rod 15 is fixedly connected to the facing side of each slider 24. A hinge rod 16 is hinged to the end of each moving rod 15, and the two hinge rods 16 are hinged together. A pressing mechanism for pressing the hinge rods 16 is installed on the box body 2. A pin 26 is fixedly connected to the bottom of each slider 24. The upper tube body 1 has two through holes 27 inside, into which the pin 26 is inserted. The extension rod 4 has multiple limiting pin holes 19 inside, which are divided into unfolding limiting holes and retracting limiting holes. The pin 26 is inserted into the limiting pin holes 19. The box body 2 has two first insert rods 28 fixedly connected inside, both of which are inserted into the pin 26. A first spring 29 is installed inside the pin 26.

[0020] The pressing mechanism includes a pressing cover 3, which is sleeved on the outside of the box body 2. The hinge rod 16 is located inside the lower part of the pressing cover 3. Two second insert rods 30 are fixedly connected to the bottom of the pressing cover 3. Both second insert rods 30 are slidably connected to the inside of the box body 2. Two third slide grooves 32 are opened inside the box body 2. Limiting blocks 31 are slidably connected inside the two third slide grooves 32. The limiting blocks 31 are fixedly connected to one end of the second insert rods 30. A second spring 33 is provided at the bottom of the inner part of the third slide groove 32. Two stops 20 are fixedly connected to the bottom of the pressing cover 3. The hinge rod 16 is located between the two stops 20.

[0021] The stop block 20 limits the movement of both sides of the hinge rod 16.

[0022] The extension rod 4 has four slide rails 5 arranged at equal intervals on its outer circumference, and the upper tube 1 has four first slide grooves 17 arranged at equal intervals on its inner circumference. The slide rails 5 are slidably connected to the inside of the first slide grooves 17.

[0023] The upper tube 1 is externally fixedly connected to a fixing block 8, and the fixing block 8 is externally fixedly connected to a Velcro strap 9.

[0024] The upper tube 1 is fixedly connected to a handle 11 at its end, a sponge ring 12 is glued to the outside of the handle 11, and a wrist strap 13 is fixedly connected to the outside of the handle 11.

[0025] Among them, the lower tube body 7 is fixedly connected to the outside of the baffle 22, and the bottom of the lower tube body 7 is fitted with a rod tip protective sleeve 23.

[0026] When the invention needs to be unfolded or retracted, the pressing cover 3 is pressed down and moved downwards. The pressing cover 3 simultaneously presses down the hinged rods 16 that are hinged to each other. After being subjected to force, the hinged rods 16 push the moving rods 15 to both sides. The moving rods 15 drive the sliders 24 to slide towards each other in the second sliding groove 25. When the sliders 24 slide, they pull the bottom pin 26, causing the pin 26 to be pulled out from the limiting pin hole 19 on the extension rod 4. At the same time, the pin 26 compresses the first spring 29 on the first insert rod 28, and the pin 26 retracts synchronously from the through hole 27 of the upper tube 1. At this time, the extension rod 4 is released from the limit and can be pulled out relative to the upper tube 1.

[0027] When unfolding and adjusting, pull the extension rod 4 to the required length. The slide rail 5 outside the extension rod 4 slides along the first slide groove 17 inside the upper tube 1 to guide and prevent rotational deviation. Release the pressing cover 3, and the pin 26 resets under the elastic force of the first spring 29 and is inserted into the unfolding limit hole 19 of the corresponding length to complete the fixation after the length is unfolded.

[0028] When retracting and adjusting, push the extension rod 4 back into the upper tube 1 to the retracted position, release the pressing cover 3, and the pin 26 will reset under the elastic force of the first spring 29 and be inserted into the retracting limit hole 19 to complete the retraction and fixation of the cane.

[0029] Example 2 Please see Figures 2-7 An embodiment of the present invention provides an adjustable-length hiking stick for travel, comprising: an upper tube 1, an extension rod 4 slidably connected inside the upper tube 1, a support plate 21 fixedly connected inside the extension rod 4, and a limiting mechanism for limiting the extension rod 4 installed outside the upper tube 1; a connecting block 14 is also fixedly connected inside the extension rod 4, an elastic connecting rope 6 is fixedly connected outside the connecting block 14, one end of the elastic connecting rope 6 is fixedly connected to a lower tube 7, and one end of the lower tube 7 is threadedly connected to the inside of the extension rod 4.

[0030] The limiting mechanism includes a box body 2, which is fixedly connected to the outside of the upper tube body 1. The box body 2 has two second sliding grooves 25 inside, each containing a slider 24. A moving rod 15 is fixedly connected to the facing side of each slider 24. A hinge rod 16 is hinged to the end of each moving rod 15, and the two hinge rods 16 are hinged together. A pressing mechanism for pressing the hinge rods 16 is installed on the box body 2. A pin 26 is fixedly connected to the bottom of each slider 24. The upper tube body 1 has two through holes 27 inside, into which the pin 26 is inserted. The extension rod 4 has multiple limiting pin holes 19 inside, which are divided into unfolding limiting holes and retracting limiting holes. The pin 26 is inserted into the limiting pin holes 19. The box body 2 has two first insert rods 28 fixedly connected inside, both of which are inserted into the pin 26. A first spring 29 is installed inside the pin 26.

[0031] The pressing mechanism includes a pressing cover 3, which is sleeved on the outside of the box body 2. The hinge rod 16 is located inside the lower part of the pressing cover 3. Two second insert rods 30 are fixedly connected to the bottom of the pressing cover 3. Both second insert rods 30 are slidably connected to the inside of the box body 2. Two third slide grooves 32 are opened inside the box body 2. Limiting blocks 31 are slidably connected inside the two third slide grooves 32. The limiting blocks 31 are fixedly connected to one end of the second insert rods 30. A second spring 33 is provided at the bottom of the inner part of the third slide groove 32. Two stops 20 are fixedly connected to the bottom of the pressing cover 3. The hinge rod 16 is located between the two stops 20.

[0032] The extension rod 4 has four slide rails 5 arranged at equal intervals on its outer circumference, and the upper tube 1 has four first slide grooves 17 arranged at equal intervals on its inner circumference. The slide rails 5 are slidably connected to the inside of the first slide grooves 17.

[0033] The upper tube 1 is externally fixedly connected to a fixing block 8, and the fixing block 8 is externally fixedly connected to a Velcro strap 9.

[0034] The upper tube 1 is fixedly connected to a handle 11 at its end, a sponge ring 12 is glued to the outside of the handle 11, and a wrist strap 13 is fixedly connected to the outside of the handle 11.

[0035] Among them, the lower tube body 7 is fixedly connected to the outside of the baffle 22, and the bottom of the lower tube body 7 is fitted with a rod tip protective sleeve 23.

[0036] In addition, when the pressing cover 3 is pressed down, the second insert 30 at its bottom drives the limiting block 31 to slide downward in the third slide groove 32 and compress the second spring 33; when the pressing cover 3 is released, the second spring 33 releases its elastic force to push the limiting block 31 to move upward, driving the second insert 30 and the pressing cover 3 to return to the highest pressing position. At the same time, the first spring 29 pushes the pin 26 to always maintain an inward pushing force, continuously limiting the extension rod 4 and preventing it from loosening.

[0037] The support plate 21 inside the extension rod 4 provides structural support for the rod body, effectively preventing the upper tube 1 from bending under pressure during use; the connecting block 14 inside the extension rod 4 is connected to the elastic connecting rope 6, and the other end of the elastic connecting rope 6 is connected to the lower tube 7, and the lower tube 7 is threadedly connected to the extension rod 4. The double connection ensures the stability of the lower tube 7, and the elastic connecting rope 6 can prevent the lower tube 7 from falling off.

[0038] The handle 11 at the end of the upper tube 1 is covered with a sponge ring 12 to improve grip comfort, and the wrist strap 13 prevents the cane from slipping.

[0039] The Velcro strap 9 on the fixing block 8 can be used to bind and store the cane after it is folded up.

[0040] The baffle 22 on the outside of the lower tube 7 serves as a limiting and protective function, and the rod tip protective sleeve 23 at the bottom protects the rod tip and prevents the rod tip from being scratched when idle.

[0041] Based on the above technical solution, the working steps of this solution are summarized as follows: When the invention needs to be unfolded or retracted, press the pressing cover 3 and move it downwards. The pressing cover 3 simultaneously presses down the hinged rods 16 that are hinged to each other. After being subjected to force, the hinged rods 16 push the moving rods 15 to both sides. The moving rods 15 drive the sliders 24 to slide towards each other in the second sliding groove 25. When the sliders 24 slide, they pull the bottom pin 26, causing the pin 26 to be pulled out from the limiting pin hole 19 on the extension rod 4. At the same time, the pin 26 compresses the first spring 29 on the first insert rod 28, and the pin 26 retracts synchronously from the through hole 27 of the upper tube 1. At this time, the extension rod 4 is released from the limit and can be pulled out relative to the upper tube 1. When extending and adjusting, pull the extension rod 4 to the desired length. The slide rail 5 on the outside of the extension rod 4 slides along the first slide groove 17 inside the upper tube 1 to guide and prevent rotational deviation. Release the pressing cover 3, and the pin 26 returns to its original position under the elastic force of the first spring 29, inserting into the corresponding length extension limit hole 19 to complete the fixation after extension. When retracting and adjusting, push the extension rod 4 back into the upper tube 1 to the retracted position, release the pressing cover 3, and the pin 26 returns to its original position under the elastic force of the first spring 29, inserting into the retracting limit hole 19 to complete the retraction and fixation of the cane.
