The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0030] The "first", "second" in the present application do not represent the specific number and order, but are only used for the name distinction.

[0031] Before the specific embodiments of the present application are described in detail, the prior art is briefly introduced. The current trekking pole technology has many shortcomings in practical application: first, the problem of single function is significant, most trekking poles can only provide basic support function, and it is difficult to meet the needs of complex outdoor scenes, users need to carry additional equipment such as knives, flashlights, and clamping tools, resulting in increased weight and inconvenience; second, the safety risk is prominent, some integrated tool trekking poles (such as knives) lack effective storage and protection structure, and are easy to cause scratches and accidental touch during carrying or using; third, the environmental adaptability is poor, the existing products are not optimized for special terrains such as snow mountains and deserts, and lack pressure buffering and anti-skid design, which makes it difficult to disperse walking pressure and increase friction, affecting the stability of use; fourth, the operation convenience is insufficient, the existing trekking poles lack quick-response mechanical control structure, and cannot efficiently realize tool switching and article grabbing; finally, the maintenance cost is high, the tool parts (such as knives) are severely worn after outdoor use, but there is no matching convenient grinding device, resulting in high maintenance difficulty and cost.

[0032] To improve the safety and convenience of the use of the trekking pole, as shown in Figures 1-8 An embodiment of the present application provides a trekking pole, which comprises a handle 1, a pole, a knife, a first mechanical button 4, and a first power transmission mechanism. The bottom of the handle 1 is fixedly connected with the pole. The handle 1 is provided with a storage cavity matched with the knife. The knife is in transmission connection with the first power transmission mechanism. The second mechanical button is installed on the handle 1. The first power transmission mechanism is configured to drive the knife to act under the control of the first mechanical button 4. When the first mechanical button 4 is pressed, the knife is driven by the first power transmission mechanism to rotate out of the storage cavity. When the first mechanical button 4 is released, the knife driven by the first power transmission mechanism to rotate out of the storage cavity is retracted into the storage cavity.

[0033] As a preferred technical solution, the first power transmission mechanism comprises a first rotating shaft and a planetary gear reduction motor. The first rotating shaft is rotatably installed in the storage cavity through a bearing. One end of the knife is fixedly connected with the first rotating shaft. The output shaft of the planetary gear reduction motor is in transmission connection with the first rotating shaft. The first mechanical button 4 is used to control the start and stop of the planetary gear reduction motor to drive the knife to rotate out of the storage cavity or retract into the storage cavity. Exemplarily, the storage cavity is arranged at the front end of the handle 1, the first rotating shaft is rotatably installed in the storage cavity, when the first mechanical button is pressed, the first rotating shaft is driven by the planetary gear reduction motor to rotate counterclockwise, so that the knife rotates a certain angle (such as 120 degrees) and rotates out of the storage cavity, when the first mechanical button is released, the first rotating shaft is driven by the planetary gear reduction motor to rotate clockwise, so that the knife is retracted into the storage cavity.

[0034] The tool is a sickle 14, the back of the sickle 14 is provided with staggered trapezoidal teeth. The trekking pole also comprises a terrazzo crystal 2, one side of the handle 1 is provided with a recessed groove, the terrazzo crystal 2 is embedded in the recessed groove, and the surface of the terrazzo crystal 2 is provided with protruding particles.

[0035] Specifically, the handle 1 is the core component of the multifunctional trekking pole which directly contacts with the user and integrates multiple functions, and its design not only focuses on ergonomic principles to achieve a comfortable holding experience, but also integrates multiple important functional components as the control center of the whole system. The overall shape of the handle 1 is an "L" type curved surface, which is designed according to the characteristics of most adult hand shapes and is constructed as a natural curved structure that fits the palm to enhance control stability and reduce hand fatigue caused by long-term holding. The handle 1 skeleton can be made of impact-resistant and high-strength ABS engineering plastic, which has excellent structural stability, cold and heat resistance, and can adapt to various outdoor extreme environments including high altitude, high humidity, low temperature, and high temperature.

[0036] The outer layer of the skeleton is covered with a layer of high-elasticity rubber material such as TPR (Thermo-Plastic-Rubber material) or EPDM (Ethylene Propylene Diene Monomer). The rubber not only has a soft and comfortable grip, but also has excellent anti-slip ability and wear resistance. At the same time, its surface is textured to form irregular granular protrusions, which can further enhance the friction between the hand and the handle 1. Even in a rainy environment or when the user has a lot of sweat, it can be firmly held and not easily slipped. In addition, to enhance the fine fit when holding, the handle 1 is specially provided with five finger groove type recesses at the lower end. The recesses are designed according to the natural arrangement of human fingers, each recess is about 1.5 cm wide, about 3 mm deep, and about 2 cm long, and the arrangement direction is consistent with the natural curvature of the fingers. It can effectively guide the positioning of the fingers and improve the stability and accuracy of holding. The handle 1 can be designed as a multifunctional integrated hollow structure, with modular cavity partition arrangement for easy installation and maintenance of different functional components. The storage cavity is used to store the sickle 14, and the cavity is a custom concave groove matched with the sickle 14. The sickle 14 can completely hide its blade part in the unused state and be closed and protected by the handle cover 13 to avoid scratches caused by accidental touch. That is, the handle cover 13 is fixed on the opening edge of the storage cavity by buckling or screwing.

[0037] The sickle 14 is controlled by the first rotating shaft and the first mechanical button 4. When in use, the first rotating shaft is driven to rotate by pressing the first mechanical button 4, and the sickle 14 is driven to rotate out or retract. The first rotating shaft is arranged in the middle cavity of the handle 1, and is driven to rotate by a planetary gear reduction motor, thereby realizing the linkage control among the first rotating shaft, the first mechanical button 4 and the sickle 14. The structure not only simplifies the operation steps, but also improves the response speed and use flexibility. The first mechanical button 4 adopts a metal spring-loaded structure, and is covered with a rubber button cap, so that it can be conveniently pressed and controlled by the thumb or index finger in the natural state of the fingers.

[0038] The terrazzo crystal 2 is installed in an embedded manner. For example, the ceramic grinding wheel terrazzo can be embedded in a recessed groove, and a silica gel edge is arranged around the terrazzo crystal 2 to avoid scratching the skin of the user in a non-use state. The terrazzo crystal 2 is used for temporarily grinding the blade of the sickle 14 to ensure the long-term sharpness of the sickle 14, and can also be used for grinding other portable knives or metal tools, which has high practicability. A hanging handle 5 connecting hole or a wrist strap slot is arranged at a position of the handle 1. The user can install an adjustable nylon wrist strap, a hand anti-falling rope or a mountaineering hook according to needs, so as to release the hand pressure during walking or hang the walking stick on a backpack, a tree branch or the like when not in use, thereby improving the carrying convenience.

[0039] A standard size flashlight socket 6 can also be arranged on the handle 1. The flashlight socket 6 is a Φ18mm circular rubber sleeve structure, which supports the installation of an LED flashlight through screwing or buckling. The structure is embedded with a positioning groove and a shockproof washer, which ensures that the flashlight is not easy to fall off during vibration. The angle of the socket is set to about 15° downward inclined angle, which ensures that the illumination range of the flashlight covers the path under the user, and is suitable for night walking or use in a sudden power failure environment. The bottom of the handle 1 is connected with the stick rod through a plug-in structure. The plug-in area is provided with a positioning clamping groove and a metal lock ring, which forms a fixing mechanism in linkage with the spring button 9, and can realize the length adjustment and locking function of the walking stick. The tail structure of the handle 1 is matched with the bottom structure of the stick body to install a rubber cap 8 or a mud drag 7, which is used to improve the ground adhesion and cushioning.

[0040] In summary, the handle 1 is not only a bridge connecting the user and the whole walking stick, but also a central module integrating operation control, function conversion and structure connection. It has many advantages such as precise ergonomic design, reasonable material process, high function module integration, strong safety and comfort, etc., and is the key technical core to realize the innovation and practicality of the multifunctional walking stick.

[0041] The waterstone crystal 2 is one of the most critical functional accessories in the present application, and its main function is to sharpen the sickle 14 in emergency situations to ensure that it always maintains good sharpness, thereby improving the efficiency and safety of plant cleaning, road opening operations, and defense against wild animals in outdoor environments. The waterstone crystal 2 is arranged in a special recess on one side of the outer surface of the handle 1, and has an overall arc-shaped elongated strip shape, with a length of about 60 mm, a width of about 10 mm, and a thickness of about 4 mm. Under the premise of maintaining small size and portability, it has good grinding area and operation stability. The arc-shaped structure design of the waterstone crystal 2 is based on the optimization of the finger direction when holding the hiking stick and the movement trajectory of the sickle 14, so that the user can naturally fit the blade to the surface of the grinding stone for back and forth grinding without adjusting the posture. The operation feels smooth and efficient. The material of the waterstone crystal 2 is industrial-grade high-hardness ceramic grinding wheel particles, mainly composed of alumina or silicon carbide, with a Mohs hardness of 8.5 or above, and has strong wear resistance and long service life. In order to improve the stability and safety of the user, the waterstone crystal 2 adopts an embedded structure, which is embedded in the recess of the handle 1 and fixed by high-strength resin glue. The edge part is wrapped and edged with silicone rubber pads, which improves the smoothness of the overall grip and prevents cuts or scratches on the skin. On the other hand, it also prevents sharp particles from being exposed in the non-use state, ensuring safety during carrying. This structure design takes into account the actual situation that users may not be able to use professional knife sharpening equipment in the wild, so the surface of the waterstone crystal 2 is designed with a certain roughness and irregular texture, with an average roughness Rz controlled between 20-25 microns, which can quickly sharpen the sickle 14 blade, and is also suitable for other commonly used metal tools such as folding knives and multi-purpose knives.

[0042] In addition, a buffer groove slightly lower than the surface of the handle 1 is reserved below the waterstone crystal 2 body, so that even if the palm and the grinding stone area are in contact when the hiker holds it, it will not be uncomfortable. In order to enhance the overall anti-slip performance, micro convex particles are also designed on the upper surface of the grinding stone, so that the sickle 14 will not slip during grinding, further improving the efficiency and safety of knife sharpening. The overall structure takes into account practicality, safety and concealment, ensuring that the sickle 14 has sustained operation capability in outdoor situations, and will not affect the overall appearance and comfortable grip of the handle 1 due to the protruding structure. It is one of the important embodiments of the multi-functional integrated structure design of the present application.

[0043] The water mill stone crystal 2 can be used independently without additional power or accessories, belongs to a passive emergency tool, meets the design concept of lightweight outdoor equipment, and has high temperature resistance and corrosion resistance, can maintain stable performance even if exposed to humid, muddy or high salt environment for a long time, and has a service life much longer than that of ordinary outdoor equipment consumables. Overall, the water mill stone crystal 2 realizes great expansion of outdoor emergency functions without increasing the difficulty of use through seamless integration with the handle 1 structure and precise adaptation to human ergonomics, and is one of the key designs of the application to improve tool maintenance and safety response capabilities.

[0044] The mountaineering pole can provide effective storage and protection structure for the knife by setting a storage cavity matched with the knife on the handle 1 and by the first mechanical button 4 and the first power transmission mechanism controlling the knife to rotate out and retract relative to the storage cavity, can facilitate the user to control the action of the knife through the first mechanical button 4, improve the safety and convenience of use, and solve the problem of lack of effective storage and protection structure in the existing mountaineering pole, which has certain safety hazards in use.

[0045] As a preferred technical solution, the mountaineering pole further comprises a mechanical arm 11, a second mechanical button 15 and a second power transmission mechanism, the second mechanical button is installed on the handle 1, the second power transmission mechanism is installed in the inner cavity of the pole and is in transmission connection with the mechanical arm 11, and the second power transmission mechanism is configured to drive the mechanical arm 11 to act under the control of the second mechanical button 15. When the second mechanical button 15 is pressed, the mechanical arm 11 is driven to expand by the second power transmission mechanism, and when the second mechanical button 15 is released, the expanded mechanical arm 11 is driven to close by the second power mechanism.

[0046] The second mechanical button 15 comprises a second button cap and a second spring, the second button cap and the second spring are connected through a hollow shaft, the second power transmission mechanism comprises a second steel wire rope and a second rotating shaft 12, the second rotating shaft 12 is rotatably installed in the inner cavity side wall of the pole, the second steel wire rope is arranged in the inner cavity of the pole and one end is in transmission connection with the second button cap, the other end of the second steel wire rope is in transmission connection with the second rotating shaft 12, and the rotating shaft is in transmission connection with the mechanical arm 11.

[0047] The second power transmission mechanism further comprises a guide pulley set and a gear reduction set, the second steel wire rope is wound on the guide pulley set, the guide pulley set is used for converting displacement of the second steel wire rope along the length direction of the pole rod into angular rotation of the second rotating shaft 12 around the axis, the second rotating shaft 12 is in transmission connection with the mechanical arm 11 through the gear reduction set, and the gear reduction set is used for converting rotation of the second rotating shaft 12 into the unfolding and closing action of the mechanical arm 11.

[0048] The second mechanical button 15 is a key control unit in the multifunctional mountaineering pole, and the structural design and function implementation of the second mechanical button 15 are particularly important for the multipurpose expansion of the mountaineering pole, especially in the process of controlling the unfolding and retraction of the mechanical arm 11. The second mechanical button 15 is integrally and modularly integrated, and the external structure is a second button cap made of industrial-grade impact-resistant ABS plastic. The second button cap has a micro-slip particle texture on the surface, which can ensure operation sensitivity and finger friction in high humidity, rainy and snowy weather or when the user wears gloves, avoiding accidental sliding or accidental touch. The second button cap is in an oval raised state, the edge of which is slightly higher than the surface of the handle 1 and maintains an inclined angle of about 2° with the handle 1, which conforms to the natural bending direction of the human finger and facilitates the natural pressing and starting of the index finger or middle finger. A high-strength spring mechanism is arranged below the second button cap, the spring is made of stainless steel, has a diameter of about 8 mm, a free length of about 20 mm and a maximum compression stroke of 15 mm, has excellent elastic recovery performance and fatigue strength, and can quickly and stably restore the button to its original position after the user presses the button, ensuring that each operation is clear and reliable. The second button cap and the second spring are connected through a hollow shaft, and the vertical movement of the button can be completely compressed downward along the internal channel of the handle 1 (perpendicular to the length direction of the pole rod), forming linear displacement.

[0049] The second steel wire rope is a galvanized steel wire rope with a diameter of about 1 mm and a length of about 12 cm, one end of which is fixed to the bottom of the second button cap, and the other end penetrates through the guide groove in the inside of the handle 1, then winds through two low-friction guide pulleys, and finally connects to the second rotating shaft 12. The guide pulleys are made of nylon material and contain metal bearings, which can effectively reduce the friction and wear of the second steel wire rope, while improving the transmission efficiency. When the user presses the second mechanical button 15, the second steel wire rope is pulled inward, driving the second rotating shaft 12 to rotate by a certain angle, thereby triggering the unfolding or closing action of the mechanical arm 11. The second rotating shaft 12 and the mechanical arm 11 are connected through a set of micro gear reduction mechanism, which can amplify the displacement of the second mechanical button 15 and control the smoothness and force of the arm action, ensuring that even a slight button press can effectively drive the mechanical arm 11 to complete the clamping action. In addition, the second mechanical button 15 and the second steel wire rope connection part are provided with a limiting nut to prevent the steel wire from being pulled too much, causing the system to lose control or break.

[0050] In order to improve the adaptability of the second mechanical button 15 in actual field environment, the entire second mechanical button 15 is covered with a flexible silicone waterproof ring, which is sealed between the handle 1 shell through hot-pressing adhesion, effectively preventing rainwater, dust, sand and other impurities from penetrating into the button internal structure, ensuring the reliability and durability of long-term use. The second mechanical button 15 is embedded in the handle 1 about 4 cm below the front side, just at the natural touch point when the human body index finger bends, so users can complete the operation without adjusting the grip, greatly improving the convenience and emergency response speed. In the actual operation process, the user only needs to press the button gently, and the internal second steel wire rope is immediately pulled tight, driving the second rotating shaft 12 to rotate clockwise by about 45 degrees. At this rotation angle, the mechanical arm 11 quickly opens to perform clamping or gripping action. When the user releases the button, the second spring immediately pushes the second button cap back to its original position, and the second steel wire rope rebounds, the second rotating shaft 12 rotates in the opposite direction, and the mechanical arm 11 returns to the original folded state and is stored in the stick rod. The entire mechanical system design of the second mechanical button 15 emphasizes quick response, reliable action, and strong durability, which can maintain excellent performance in various complex outdoor environments. It not only can realize multiple rapid operations without significant performance degradation, but also is not prone to jamming or rusting in cold, high humidity, and high dust environments. It is a key link to realize the core concept of "tool combination" of the invention.

[0051] As a preferred technical solution, the stick rod is a telescopic rod 3, which includes an inner tube, an outer tube, and a locking structure. The outer tube is sleeved on the inner tube, and the locking structure is installed between the inner tube and the outer tube. The locking structure is used to lock the relative position of the inner tube and the outer tube.

[0052] Specifically, the telescopic device 3 is the core adjustment component of the multifunctional trekking pole, and its structural design directly determines the flexibility, portability and stability of the whole trekking pole. The telescopic device 3 is composed of two main components, namely the inner tube and the outer tube, both of which are made of high-strength, lightweight aviation-grade aluminum alloy material (such as 7075-T6 aluminum). This material has very high tensile strength, good corrosion resistance and low density characteristics, which not only ensures the strength of the overall structure, but also takes into account the lightness when carrying. The outer diameter of the outer tube is about 18 mm, and the outer diameter of the inner tube is about 16 mm. Both of them are controlled by high-precision concentricity and straightness during mechanical processing, ensuring smooth sliding, no jamming or shaking during telescoping. The surfaces of the inner and outer tubes are anodized to form a layer of strong aluminum oxide film, improving wear resistance and having certain waterproof and anti-pollution effects.

[0053] In order to realize the height-adjustable locking function, the telescopic device 3 is designed with two main control mechanisms, one of which is a rotating locking mechanism, and the other is a spring button 9 positioning system. The rotating locking mechanism is located in the overlapping area of the inner and outer tubes. The inner wall of the outer tube is provided with an annular locking thread, and the outer wall of the inner tube is provided with a spiral pressure ring matching the annular locking thread. The annular locking thread and the spiral pressure ring constitute the spiral locking mechanism. By rotating the outer tube, the two threads can be engaged and locked, thereby realizing friction locking at any position. Users can lock by rotating clockwise and unlock by rotating counterclockwise, and the operation process is simple and reliable. The second mechanism is the spring button 9. The inner tube is provided with positioning holes (with a spacing of about 10 cm) on the side wall along the axis direction, and the spring button 9 is installed on the outer tube. When the length of the pole is adjusted by pulling the inner tube and / or the outer tube, the spring button 9 is automatically ejected and clamped into the positioning hole under the spring tension, thereby forming a mechanical lock. The head of the spring button 9 is designed as a ball head. When the user pulls the inner tube to adjust the length, the button is automatically ejected and clamped into the positioning hole under the spring tension, thereby forming a mechanical lock. It has the characteristics of accurate positioning and stable load bearing, and is especially suitable for scenes with standard length requirements.

[0054] The spring button 9 is an indispensable key mechanical component in the multifunctional trekking pole extender 3, mainly used to realize the quick adjustment and stable locking of the length of the trekking pole. Its design concept aims to balance the convenience of operation and the reliability of structure, ensuring that users can quickly adjust the length of the trekking pole in complex outdoor environments, while ensuring that the length of the adjusted pole body is stable and does not slip, greatly improving the safety and comfort of use. The core structure of the spring button 9 is composed of a small metal elastic button. The elastic button is made of high-strength stainless steel or alloy steel to ensure sufficient elasticity and wear resistance during long-term use. The surface of the elastic button is covered with a layer of high-elasticity rubber protective sleeve, which not only effectively improves the feel when pressing, but also prevents dust and sand from entering the button mechanism, thereby enhancing the dustproof and corrosion-resistant ability, adapting to the changing outdoor environment. The spring button 9 is tightly connected with the telescopic tube through a precise lock bead structure. This lock bead mechanism usually includes several steel balls embedded between the annular grooves of the button shell and the corresponding hole positions of the outer tube of the telescopic tube. When the spring button 9 is in the pop-up state, the steel balls are embedded in the multiple positioning holes of the telescopic tube, thereby realizing the stable locking of the telescopic tube and preventing the pole body from slipping due to external force or its own weight. The spring button 9 is equipped with a high-elasticity compression spring, which is placed between the shaft core of the spring button 9 and the shell of the spring button 9, ensuring that the button can quickly pop up after being released, driving the steel ball to accurately enter the positioning hole and completing the automatic reset locking action.

[0055] In operation, the user only needs to press the button head covered with the rubber sleeve with his fingers, compress the internal spring, and push the steel ball out of the positioning hole of the telescopic tube, so that the inner tube can freely slide to adjust the length. After adjusting to the desired position, release the button, the spring quickly pops up, and the steel ball immediately enters the new positioning hole, completing the length locking. The design of this mechanism ensures that users can quickly adjust the length with one hand without the need for rotation or complex tool assistance, greatly improving the convenience of use. In terms of structure, the overall size of the spring button 9 is compact, with a button head diameter of about 10 mm and a length of about 20 mm, suitable for the operation requirements of outdoor wearing gloves. The mechanical parts between them are treated with anti-rust and precision machining to ensure smooth and durable use over a long period of time. The spring button 9 is installed at the connection part of the inner tube and the outer tube of the extender 3, and is fixed by nesting and screwing technology, ensuring the firmness of the button and the stability of its mechanical action. The design of the spring button 9 system also fully considers the temperature changes, sand intrusion and humidity in outdoor environments, and the internal mechanical parts are treated with anti-corrosion coating and have a protective cover to isolate foreign matter. Due to the lock bead design, the spring button 9 has the ability to position multiple lengths, and users can adjust the trekking pole to different length positions according to their needs, adapt to different terrain and height requirements, especially suitable for multi-level slopes and complex topography.

[0056] In addition, the spring button 9 also has a self-cleaning function. When the user presses and releases, the steel ball bounces under the action of the spring, effectively shaking off the attached dust and particles, ensuring the sensitivity and durability of the locking mechanism. The entire spring button 9 mechanism has undergone mechanical simulation and multiple durability tests to ensure that it can still be stably locked after repeated adjustments of tens of thousands of times, withstand external forces without accidental loosening, and meet the use requirements of trekking poles in extreme environments. In summary, the spring button 9 as the core adjustment component of the telescopic device 3, with its reasonable material selection, precise locking ball structure, effective protection design, and simple and convenient operation method, realizes the safety, stability and efficiency of the length adjustment of the multifunctional trekking pole, and is an important guarantee for the overall performance improvement of the product.

[0057] These two locking mechanisms can be used together or independently, depending on user habits and environmental needs. In terms of structural details, to improve stability and safety during use, the telescopic device 3 has a buffer rubber ring at the joint, which can absorb vibrations and impacts on the pole body, especially during travel, effectively reducing the impact force transmitted to the user's wrist. In addition, to prevent rain or dust from entering the tube cavity and affecting the service life of the telescopic structure, the telescopic device 3 has a sealing dust ring at the top and bottom of the tube, made of weather-resistant silicone rubber material, with excellent sealing performance, keeping the internal structure clean and dry in cold, humid or sandy environments. To adapt to different user heights and different mountain slope angles, the telescopic device 3 has a large length adjustment range in the structural design, with a minimum compressed state of about 60 cm, allowing users to hang it in the side pocket of the backpack or put it in the luggage, and a maximum extended state of 130 cm, meeting the needs of users of different heights to optimize the angle of the trekking pole in uphill and downhill terrain. At the same time, to further improve strength and durability, a thickened reinforcing ring is provided at the joint of the inner tube bottom and the outer tube top, which is integrally turned and formed, improving the uniformity of stress distribution and avoiding local fatigue damage caused by repeated telescoping.

[0058] In actual use, users can hold the handle 1 and the outer tube part with both hands, and quickly adjust and lock the length by pulling or rotating lightly, without the need for additional tools, with flexible adjustment range, suitable for quick response and deployment in complex outdoor environments. Overall, the telescopic device 3 not only has the adjustable height and portable storage function of traditional trekking poles, but also greatly improves the use reliability, structural stability and long-term durability of the trekking pole in extreme terrain through material upgrading, double locking mechanism and dustproof and shockproof structure, which is one of the key components to support the efficient operation of the entire multifunctional trekking pole.

[0059] The hanging handle 5 is one of the important auxiliary components of the multifunctional mountaineering stick, and its structure design not only considers the convenience of carrying and storage during mountaineering, but also fully considers the practical needs of multi-scene emergency use in complex environments. The hanging handle 5 is mainly composed of two parts, namely the flexible main body part and the fixed connection part. The flexible main body part is made of high-strength industrial nylon woven belt, with a width of about 2 cm and a thickness of about 2 mm, and has good flexibility and wear resistance. It can be used for a long time in harsh outdoor environments such as high-temperature sunshine, rain and snow, and is not easy to age, crack or break. The nylon woven belt is sealed on both sides with three reinforcing stitches, effectively preventing edge filament shedding and improving overall tear resistance. The overall length of the hanging handle 5 is about 20 cm, and it is designed to be adjustable through the built-in high-resilience elastic core rope and the elastic adjustment buckle. Users can adjust the length of the hanging handle 5 within a certain range according to the size of their palms, wrist comfort or hanging needs, and the length is stable during adjustment through the buckle locking structure, and is not easy to slide or come off. At one end of the flexible woven belt, a C-shaped stainless steel hook is provided. The hook is made of 304 stainless steel with a thickness of about 3 mm and a surface treated with anti-rust plating. The hook body has a curvature that conforms to the natural bending angle of the fingers, making it comfortable to hold. The hook port is slightly inward to form a safe closed opening to prevent the hanging object from slipping off. The opening position is provided with a small spring buckle to prevent accidental falling during shaking or vigorous movement. The other end is tightly bonded with the rear embedded groove of the handle 1 through industrial hot melt glue, and is supplemented with a threaded locking structure to enhance the firmness.

[0060] To improve the adaptability of multi-functional use scenarios, a small piece of Velcro structure is sewn in the middle section of the hanging handle 5, which can be wrapped around other shaft parts or backpack shoulder straps to form a simple fixed ring structure. In addition, when not climbing, the hanging handle 5 can be directly used to hang the trekking pole on the side of the backpack, protruding parts of rocks, branches, tent supports, etc., to release both hands and enhance the degree of freedom of operation. When the risk of sliding is high, the user can also wrap the hanging handle 5 around the wrist and tighten the length, so that the trekking pole is always attached to the hand, preventing the loss of support tools due to accidental falling. In some special cases, such as the need to tie up items or emergency fixing of tent poles, the hanging handle 5 can also be used as a binding belt, with a tensile strength of more than 30 kg, which can withstand moderate tension operations and is not easy to break or damage, showing strong strain capacity. To improve the safety of users at night, the fluorescent reflective silk is embedded in the surface of the hanging handle 5, which can reflect light significantly when illuminated at night, helping users quickly identify the position of the trekking pole and also serving as a warning sign to prevent others from stepping on or tripping. In addition, according to different use scenarios, the hanging handle 5 can also be selected in different styles, such as a closed wristband hanging handle 5 suitable for long-term wearing and wrist fixing needs, and a flexible open hanging handle 5 suitable for frequent hanging and taking scenarios to improve operation efficiency. In summary, the hanging handle 5 has been carefully designed in terms of structure, material, connection form, adjustment method and multi-functional use, fully embodying the technical innovation and practical value of the invention in improving the convenience, safety and multi-purpose integration of the climbers.

[0061] The flashlight socket 6 is one of the important integrated components of the multifunctional trekking pole of the present invention, and its structure design fully embodies the organic unity of practicality, stability and adaptability. The socket is embedded in the lower part of the central axis of the front end of the handle 1 or on the outer tube, with a Φ18mm circular standard interface size, compatible with most outdoor special LED flashlight products on the market. The inside of the hole wall of the flashlight socket 6 is covered with a ring of high-elasticity silicone rubber gasket, about 1.2mm thick, with good friction fixing ability and anti-vibration cushioning function. When the flashlight is inserted, the gasket can tightly fit the outer shell of the cylinder, forming a physical damping layer to prevent the flashlight from loosening and falling off due to shaking during vigorous exercise or climbing. In addition, to further enhance the fixing effect, a ring of bayonet fixing ring is provided on the inner wall of the socket, which is a steel limiting mechanism with a snap spring, with a nickel plating surface to prevent rust. After the flashlight is inserted into place, the bayonet can accurately fit into the positioning groove at the tail of the cylinder body, achieving double locking to ensure that it remains firmly in place even in conditions of shaking, high-altitude shaking, sudden stopping, etc.

[0062] The overall opening angle of the flashlight socket 6 is slightly inclined downward by 15° relative to the axis of the handle 1, so that the user in the holding state, the light projection angle naturally falls on the ground path in front of the mountaineer 1.2 to 1.5 meters, effectively illuminating the environment under the foot, while avoiding direct eye glare. This angle is based on many field mountaineering tests and optimization, which can adapt to the natural pace and line of sight of most users (160-190 cm) in height. In addition, the periphery of the socket is provided with a circular groove transition structure with a height of about 2 mm, which facilitates the user to put in the dust plug when the flashlight is not installed to keep the interface clean. Considering the power demand of long-term use in the wild, the rear space of the socket is reserved for electrical interface, and some high-end models of hiking poles integrate small lithium battery modules and voltage stabilizing circuit inside, connected with the LED flashlight through Micro USB or Type-C interface, which can not only directly power, but also can be charged while walking when combined with a solar folding charging panel, improving energy self-sufficiency. The electrical interface adopts double-layer waterproof sealing design, and the socket body adopts IP65 level standard, with rainproof, dustproof and sandproof performance, ensuring stable operation in extreme environments such as rainforest, snow mountain and desert. In addition, the outer circle of the flashlight socket 6 is also provided with a circle of reflective coating to improve the recognition and emergency lighting reflection function when used at night, and the overall structure is compact and precise. The socket and handle 1 are integrally formed by internal thread tightening structure, and are provided with internal reinforcing rib, which can effectively withstand the weight of flashlight and external impact, avoiding interface loosening or deformation. This design takes into account the quick replacement of lighting equipment, convenient installation, stable use and environmental adaptability, and is an important auxiliary component of the invented hiking pole for weak light or no light environment such as night, tunnel and forest, effectively expanding the use time and space of the hiking pole, significantly enhancing its practical value and market competitiveness.

[0063] The mud drag 7 is an important part of the multifunctional trekking pole, and is specially designed for soft ground such as snow, sand and mud environment, so as to enhance the support and stability of the trekking pole. The structure adopts a disc-shaped design with a diameter of about 70 mm, and the overall shape is disc-shaped, which not only ensures sufficient ground contact area, but also facilitates quick installation and disassembly of the user in different terrain conditions. The main material of the mud drag 7 is high-strength engineering plastic, which has the properties of light weight and wear resistance, and can withstand mechanical wear and tear and harsh weather conditions during long-term outdoor use. The surface of the engineering plastic material is specially treated and has a certain anti-slip effect, which prevents the mud drag 7 from slipping due to wetness and improves the overall safety performance. The center of the mud drag 7 is designed with a through hole matched with the tip of the trekking pole. The size of the through hole is accurately controlled to ensure that it can be tightly fitted on the top of the rubber cap 8, and at the same time, it will not affect the direct contact of the tip with the ground to enhance the penetration of the tip. In order to ensure the stable connection between the mud drag 7 and the rubber cap 8, the mud drag 7 is equipped with a screw type fixing structure. The user only needs to rotate the mud drag 7 clockwise to easily lock it on the rubber cap 8. The rotation angle and the buckle structure are precisely designed to ensure that the mud drag 7 will not accidentally fall off even in bumpy mountainous terrain.

[0064] At the same time, in order to facilitate quick disassembly, the screw type fixing structure takes into account the force and convenience when designing, ensuring that the user can easily remove the mud drag 7 when needed to adapt to hard ground without using additional tools. The surface of the mud drag 7 is provided with radial anti-slip textures. These textures not only increase the friction coefficient between the ground, but also effectively drain water and mud, avoiding the accumulation of mud and sand on the disc surface, which reduces the contact area or causes the phenomenon of slipping. These anti-slip textures are designed according to the human foot pressure distribution, which improves the overall grip and stability. The bottom of the mud drag 7 is slightly arc-shaped, which makes it better fit the ground curve, improves the uniform distribution of the contact area, and avoids the phenomenon of sinking into soft mud due to excessive local stress. In addition, the edge of the mud drag 7 is designed with a small raised tooth structure, which enhances the grip effect on soft ground, helping to prevent sliding and sinking.

[0065] In terms of function, the mud drag 7 effectively disperses the pressure from the user's body weight by significantly increasing the contact area at the bottom of the trekking pole, preventing the trekking pole from sinking too deeply into soft ground, thereby ensuring the user's walking stability and safety in various complex terrain environments. At the same time, the disc-shaped structure of the mud drag 7 can also prevent the trekking pole from penetrating too deeply into the snow layer when walking in the snow, reducing the user's physical exertion and improving the efficiency of mountain climbing. The design of the mud drag 7 fully considers various usage scenarios, not only suitable for outdoor mountaineering, hiking, but also suitable for field exploration, search and rescue, and polar exploration. Its structure is sturdy, lightweight, easy to carry and replace, greatly improving the application range and practical value of the multifunctional trekking pole. In summary, the mud drag 7 realizes the effective improvement of the supporting performance of the bottom of the trekking pole through reasonable material selection, precise size design, ingenious screw-on fixing structure and efficient anti-skid texture arrangement, and is an indispensable important part of the invention, ensuring that users have a safer, more stable and efficient mountaineering experience in complex outdoor environments.

[0066] The rubber cap 8 is a key end protection component of the multifunctional trekking pole, and its structural design and material selection have a very important influence on the use performance of the whole trekking pole. The rubber cap 8 is installed at the lowermost end of the trekking pole, tightly covering the outer wall of the metal tube at the end of the extender 3, forming the first buffer interface of the trekking pole in contact with the ground. The rubber cap 8 is made of high-wear-resistant nitrile rubber material, which has excellent elasticity, wear resistance and tear resistance, and can withstand the friction and impact of various complex terrains on the end of the trekking pole, thereby greatly improving the durability and service life of the trekking pole. The structural design of the rubber cap 8 fully considers the use requirements of the trekking pole on hard ground such as rocks, gravel and concrete, and its bottom surface adopts a concave-convex interlaced anti-skid texture design. These textures are moderately deep and radially distributed, ensuring excellent friction coefficient on various hard ground, effectively preventing the trekking pole from slipping on slopes or slippery surfaces, and improving the safety of the user.

[0067] The rubber cap 8 is internally provided with a special buffer layer, which is usually made of high-density foam rubber or elastic silica gel, with a thickness of about 2-4 mm. Its main function is to absorb and alleviate the impact force generated when the tip of the trekking pole comes into contact with the ground, reducing vibration transmission to the user's wrist and elbow, thereby reducing fatigue and potential muscle and joint damage caused by long-term use of the trekking pole. The buffer layer is firmly combined with the outer layer of wear-resistant rubber cap 8 through internal embedding structure, which not only ensures the overall stability of the structure, but also ensures the durability and consistency of the buffering effect. The outer shape of the rubber cap 8 is optimized by ergonomic design, with the side wall thickness gradually thickening, thereby enhancing its deformation recovery ability when under stress, allowing it to effectively disperse local pressure when encountering irregular rocks or protrusions, and preventing the rubber cap 8 from cracking or premature damage due to excessive local stress. The rubber cap 8 and the trekking pole shaft are designed through nested cooperation, with a cylindrical structure whose inner diameter is slightly smaller than the outer diameter of the extender 3, cooperating with the resilience of elastic material to achieve seamless and tight installation, preventing the rubber cap 8 from falling off during use, while being easy to install and remove, making it convenient for users to replace the rubber cap 8 to adapt to different use environments. The color design of the rubber cap 8 usually adopts dark colors such as black or dark gray, which not only facilitates the concealment of soil stains in outdoor environments, but also enhances the overall aesthetic appearance of the product. In summary, the rubber cap 8, as an indispensable end accessory for multifunctional trekking poles, effectively improves the anti-skid performance and shock absorption capacity of the trekking pole in hard ground environments, significantly improves the user's walking stability and comfort, and enhances the safety and durability of the product, providing users with a more reliable and comfortable trekking experience.

[0068] The trekking pole also includes a pole cover 10. The pole cover 10 is integrally formed of high-strength polycarbonate (PC) material, and its special molecular structure endows the material with excellent impact resistance, weather resistance and flame resistance. The surface is treated with frosted finish to enhance friction for easy screwing operation. The pole cover 10 is precisely designed according to the top profile of the handle 1, and the cooperation tolerance between the two is controlled within ±0.1mm through high-precision injection molding mold, realizing airtight sealing effect. The inside of the pole cover 10 is embedded with an annular silicone rubber sealing ring, which is combined with the pole cover 10 body through secondary vulcanization process, forming a double waterproof barrier with IP67 protection level, which can effectively resist the intrusion of rain, mud and other substances, and protect the stored items dry and safe. The top of the pole cover 10 is provided with a hidden rotary buckle, which can be unlocked by 90° rotation, convenient to operate and with anti-misoperation design to prevent accidental opening leading to item falling. The inside adopts modular storage structure, and the space is flexibly divided through detachable partition plates, which can be combined into independent medicine bin, first-aid kit bin, tool bin, etc. according to needs. The bottom of the medicine bin is provided with an elastic mesh bag, which cooperates with a magnetic pressure strip to stably fix various medicine bottles and tablets; the first-aid kit bin adopts a divided grid design for classified storage of small first-aid items such as adhesive plaster and disinfecting cotton; the knife bin is provided with a safety lock, which automatically engages when the knife is inserted to prevent shaking and accidental injury, and the two unlocking buttons on both sides need to be pressed simultaneously to release the knife; the survival whistle bin is provided with a ventilation channel to ensure that the whistle can be blown quickly to send a help signal in an emergency. The inner wall of the pole cover 10 is also provided with a micro LED lighting module, which can be turned on by pressing the button on the top of the pole cover 10, facilitating quick search for items in dark environment. The lighting module is powered by a button cell, with a battery life of up to 50 hours. The battery compartment also has waterproof sealing design to ensure long-term use stability. In addition, the outside of the pole cover 10 is provided with a standard MOLLE webbing interface, which can additionally mount a compass, flint and other small outdoor tools, further expanding its functionality to meet the diversified needs of mountaineers in complex outdoor environments.

[0069] The mechanical arm 11 in the application is a small folding clamping device innovatively integrated into the trekking pole, which has high practicability and convenience. Through precise structure design and high-efficiency driving system, multifunctional application is realized. The main body is composed of two symmetrically distributed metal clamping arms, which are integrally formed by high-strength titanium alloy material, and the surface is treated by anodic oxidation. The clamping arms have light weight and high wear resistance. The thickness of a single arm is only 3 mm, which ensures that the structural strength can still be maintained in a small storage space. In the folded state, the mechanical arm 11 is completely hidden in the recess designed in the middle part (such as the upper half of the inner tube) of the pole, and the recess depth is accurately matched with the size of the clamping arm. A magnetic locking device is provided. A neodymium iron boron magnet generates an adsorption force of 5N to ensure that the clamping arm is stable and does not shake when stored, and prevents foreign matters such as sand and mud from entering and affecting operation. When it is needed to use, the user presses the second mechanical button 15 located below the handle 1. The second mechanical button 15 is designed with waterproof and dustproof, and the protection level reaches IP67. The internal micro switch triggers the unfolding mechanism of the mechanical arm 11.

[0070] Exemplarily, the second power transmission mechanism comprises a guide pulley set and a gear reduction set, and further comprises a micro stepping motor built in the telescopic rod 3. The gear reduction set is a planetary gear reduction mechanism, the output shaft of the micro stepping motor is in driving connection with the gear reduction set, and the angle adjustment of the mechanical arm 11 is realized by converting the rotation angle of the second mechanical rotating shaft into the rotation number of the output shaft. The rated torque of the motor is 0.5 N·m, the torque is amplified to 3 N·m through the gear reduction set, and the opening and closing action of the clamping arm is stable and powerful. The gear structure adopts helical tooth design, the modulus is 0.8, the transmission efficiency reaches 92%, and the running noise and wear are effectively reduced. The unfolding angle of the clamping arm can be freely adjusted between 45° and 70°, and the angle sensor is used to monitor and feed back to the control system in real time, and when the preset angle is reached, the motor is automatically powered off, and the mechanical limiting structure is used to realize accurate positioning. The end of the clamping arm is designed with a wavy anti-slip silica gel pad with a Shore hardness A60 and a 0.5mm deep rhombic groove distributed on the surface, which can effectively increase the friction force, and the measured static friction coefficient of the smooth cylinder reaches 0.8. The micro pressure sensor array is embedded below the silica gel pad, which is composed of 8 independent pressure sensing units, and can sense the stress distribution of the clamped object in real time. When it is detected that the pressure in a certain area exceeds the threshold value or the stress is uneven, the control system automatically adjusts the clamping arm angle and clamping force to ensure stable clamping of the object. The load capacity of the mechanical arm 11 is optimized and designed, and when the unfolding angle is 70°, it can stably clamp 3kg of weight, and when the unfolding angle is 45°, the maximum load capacity is increased to 5kg, which meets the needs of picking up small objects on the ground, clamping firewood, fixing water bottles and other outdoor needs. In addition, the mechanical arm 11 can also be used as a camping tool clamp, by adding a standard 1 / 4 inch threaded interface on the side of the clamping arm, photographic supports, lamps and other accessories can be quickly installed, and the use scene is expanded. In order to ensure the reliability of the mechanical arm 11 in low temperature, humid and other harsh environments, the internal transmission parts are coated with low temperature lubricating grease, the working temperature range can reach-30℃ to 60℃, and the gear box adopts a fully enclosed design with a protection level of IP65, effectively preventing water vapor and dust from entering. At the same time, the power supply system of the mechanical arm 11 adopts a low-power design, and the lithium battery built in the trekking pole supplies power through a micro wire, and after a single full charge, it can support the opening and closing operation of the mechanical arm 11 more than 500 times, and has overcurrent and overvoltage protection functions to ensure safety in use.

[0071] The second rotating shaft 12 is integrated in the precisely designed cavity structure inside the handle 1 as the core power transmission mechanism between the second mechanical button 15 and the mechanical arm 11, and realizes precise action control by adopting an innovative double-shaft linkage transmission scheme. The main body of the second rotating shaft 12 is made of high-strength stainless steel through CNC precise machining, with a shaft core diameter of 5 mm, and the surface is plated with hard chromium to improve wear resistance and corrosion resistance, ensuring long-term stable operation in complex outdoor environments. Its core transmission structure adopts a composite transmission system of "gear set + steel wire cable": a micro planetary gear set is assembled near the second mechanical button 15, which is composed of a main gear with a diameter of 3 mm and two symmetrically distributed driven gears. The gear material is powder metallurgy stainless steel, the tooth surface is treated by carburizing and quenching, and the tooth shape error is controlled within ±0.02 mm. It can efficiently convert the linear pressing motion of the second mechanical button 15 into rotary motion. An aviation-grade stainless steel wire cable with a diameter of 0.8 mm is used near the end of the mechanical arm 11. The surface of the cable is coated with a polytetrafluoroethylene lubricating layer, and it works with a high-precision guide pulley set to achieve gapless and low-friction power transmission. The two ends of the second rotating shaft 12 are fixed to the inner wall of the handle 1 through deep groove ball bearings, and the bearings are designed with waterproof and dustproof sealing, with a protection level of IP67, which can effectively prevent sand and rainwater from entering.

[0072] To realize precise opening and closing control of the mechanical arm 11, a double-limiting pin structure is provided on the second rotating shaft 12: the front-end limiting pin adopts an adjustable threaded design, and by rotating the adjusting nut, the maximum opening angle of the mechanical arm 11 can be controlled within the range of 90°-120°; the rear-end limiting pin adopts a spring-loaded structure with a built-in 0.5N constant force spring. When the mechanical arm 11 is closed in place, the limiting pin automatically clicks into the corresponding slot, ensuring that the clamping force of the clamping jaw is stable within the preset value ±5% error range. In addition, the second rotating shaft 12 also integrates an angle feedback device in the middle, which is composed of a micro potentiometer and a coding disk, which can monitor the rotation angle of the second rotating shaft 12 in real time and feedback to the control system. When abnormal resistance or angle deviation exceeds ±3° is detected, the system automatically triggers the overload protection mechanism, cutting off the power transmission through the electromagnetic clutch to avoid damage to the mechanical structure. To adapt to different use scenarios, the second rotating shaft 12 is designed with bidirectional rotation function, which can realize "push-pull" two driving modes of the mechanical arm 11 by switching the internal reversing gear set: in the conventional pickup scene, the pull driving is adopted to ensure the smooth closing of the clamping jaw; while in the scene requiring large torque output such as auxiliary climbing, the push driving mode is switched, and the transmission ratio of the planetary gear set is adjusted from 1:3 to 1:5, making the output torque of the mechanical arm 11 increase to 8N·m, meeting the high-strength operation demand. The entire second rotating shaft 12 system has undergone 100,000 consecutive opening and closing tests, with a stable transmission efficiency of more than 92%, ensuring that the mechanical arm can still achieve fast response and precise action control within 0.3 seconds in extreme environments.

[0073] The handle cover 13 adopts an innovative composite structure design, aiming to provide reliable storage protection and convenient operation experience for the sickle 14. The main frame is integrally injection molded by high-strength polycarbonate material, with the characteristics of impact resistance and wear resistance, which can effectively resist collision and scratching in complex outdoor environments. The outer layer is wrapped with a 2mm-thick anti-slip rubber layer, with a concave-convex wave-shaped texture on the surface. The anti-slip coefficient test can reach 0.85, ensuring stable grip and single-handed operation in wet, muddy, and other harsh conditions. The elastic buckle structure is the core opening and closing component of the handle cover 13, composed of an internal spring steel sheet and a positioning slot: the spring steel sheet is made of 65Mn manganese steel, with a hardness of HRC48 after quenching, excellent elasticity and fatigue life, and can withstand more than 100,000 opening and closing cycles without failure; the positioning slot is formed by precise injection molding process, with a cooperation tolerance of spring steel sheet within ±0.03mm, ensuring accurate positioning and stable locking when closed. The magnetic function module is integrated inside the handle cover 13 and connected to the handle 1, using neodymium iron boron permanent magnets, with a surface magnetic flux density of 1.2T for each magnet, and multiple magnets distributed in a matrix form, forming a magnetic array with a total suction force of 35N, ensuring that the handle cover 13 will not accidentally open in the closed state due to factors such as vibration and inclination.

[0074] In addition, the handle cover 13 is designed with an arc-shaped corner and a buffer rubber pad. The R value of the arc-shaped corner is 3mm, which can effectively prevent sharp corners from scratching the hands. The buffer rubber pad is made of EPDM rubber material with a thickness of 1.5mm, which has good shock absorption and sound insulation effect, and plays a buffering role in the closed moment, reducing collision noise. When the sickle 14 is stored in the special groove at the front end of the handle 1, the handle cover 13 can be opened by pressing the elastic buckle or gently pushing it with one hand. The opening stroke is only 15mm, and the operation time is less than 0.3 seconds. When the sickle 14 is retracted, the suction force generated by the magnetic module will automatically guide the handle cover 13 to reset and close, and the elastic buckle structure realizes double locking, ensuring the smooth surface of the handle 1, eliminating the risk of exposed blades, greatly improving the safety during holding, and also avoiding accidental scratches caused by equipment shaking during climbing, effectively protecting the user and the surrounding environment.

[0075] The sickle 14 as the core emergency function component of the mountaineering pole, the structural design deeply integrates functionality, safety and portability, aiming to provide mountaineers with efficient field operation and emergency defense capability. The overall sickle 14 adopts an integrated forging process, the blade length is accurately set to 10 cm, and the curved blade shape design conforms to ergonomics. The blade shape is optimized through fluid mechanics simulation and actual test, which can effectively reduce air resistance when swinging, and at the same time enhance the cutting efficiency when cutting vines and shrubs. The blade surface is ground with high precision, and the blade angle is controlled at 22°±1° to ensure the balance between sharpness and durability; the back of the blade is provided with a sawtooth anti-slip structure, the sawtooth is designed in staggered trapezoidal teeth, the tooth depth is 0.8 mm, and the tooth pitch is 2 mm, which can not only assist in sawing thick branches, but also be used for breaking windows, cutting ropes and other special needs in emergency situations. In terms of material, the sickle 14 selects high-strength 440C stainless steel as the base body, and the surface is covered with a 0.05 mm thick titanium alloy coating through physical vapor deposition technology. The coating not only gives the blade excellent corrosion resistance (salt spray test for 1000 hours without rust), but also significantly improves the surface hardness to HV2500, effectively resisting rock scratches and acid-base environment erosion.

[0076] In terms of storage and release mechanism, the sickle 14 is connected to the handle 1 body through a high-precision first rotating shaft, and the handle 1 is built-in and transmission-connected with a micro planetary gear reduction motor and a torque sensor. The motor rated torque reaches 0.5 N·m, which can drive the sickle 14 to complete a 90° rotation-out action in 0.3 seconds. The first rotating shaft adopts a double-bearing support structure, cooperated with a graphite lubricating coating, to ensure smooth rotation without jamming. When the sickle 14 is stored, the blade is accurately embedded in the U-shaped groove pre-set on the side of the handle 1, and the groove depth and blade thickness error is controlled within ±0.1 mm, ensuring the overall flatness after storage; externally covered with a handle cover 13 made of high-strength engineering plastic material, the handle cover 13 is fixed through a magnetic attraction and buckle double locking mechanism. The magnetic attraction structure uses a neodymium iron boron magnet with a suction force of 30 N, and the buckle is realized by a press-type spring lock tongue for secondary reinforcement to prevent accidental opening. When in use, the user only needs to press the first mechanical button 4 to trigger the signal, and the motor drives the first rotating shaft to drive the sickle 14 to rotate out.

[0077] In the multi-scene application level, the multifunctional characteristics of the sickle 14 make it a core tool for field operations and emergency defense. When opening roads in the field, the curved blade shape cooperates with the lightweight design to efficiently cut off thorns, vines and shrubs with diameters below 3 cm; the back saw teeth can handle the sawing needs of thicker branches. In the emergency defense scenario, the grip and center of gravity distribution of the sickle 14 are optimized through professional testing, allowing users to quickly form an effective defense posture. The sharpness of the blade and the combination of the back teeth can deter and counter potential threats. In addition, the torque sensor integrated at the root of the sickle 14 can monitor the force in real time. When the instantaneous force exceeds 150N, the system automatically triggers an alarm and limits the motor drive to prevent damage to the blade or injury to the user due to excessive force, ensuring safety and reliability in extreme environments.

[0078] In summary, the hiking pole described in the present application has the following structural characteristics:

[0079] 1. Multifunctional integrated structure: taking the hiking pole as the main body, the core functions of support, cutting, clamping, lighting, and polishing are highly integrated. The handle 1 is designed with ergonomic design and surface fingerprint grooves to ensure comfortable and stable grip. The front end is built-in sickle 14, which is protected by handle cover 13 and can be quickly opened and used when needed. The side is provided with a hanging handle 5 for conveniently hanging small items. The middle of the pole is installed with an extender 3, which can freely adjust the length through a spring button 9 to adapt to different heights and terrain requirements. A waterstone crystal 2 is fixedly installed near the handle 1 for quick polishing of the worn sickle 14. The end of the pole body is integrated with a mechanical arm 11, which is driven by a second shaft 12 and a second power transmission mechanism to realize flexible rotation at multiple angles and realize clamping and loosening functions with a second mechanical button 15. The side wall is provided with a flashlight socket 6 and is protected by a pole cover to meet the night lighting needs. The bottom of the pole is provided with a rubber cap 8 and a detachable mud shoe 7 to effectively cope with various complex terrains, significantly improving the practicality and versatility of the hiking pole, and completely solving the problem of single function of traditional hiking poles.

[0080] 2. Safety protection and storage structure: the sickle 14 is made of high-strength alloy steel material and has a sharp blade that can easily cut off vines and branches. To ensure safety, the sickle 14 is stored in the special storage cavity at the front end of the handle 1, which is closed by the handle cover 13. The handle cover 13 and the handle 1 are used in cooperation through a buckle or magnetic locking device to ensure that the sickle 14 does not accidentally slide out during carrying, effectively preventing scratches on the user or damage to other items. The flashlight socket 6 is provided on the side of the pole body and is sealed and protected by the pole cover to prevent dust, rain and other objects from entering, to prevent damage to the flashlight interface and to ensure the reliability and safety of the lighting function.

[0081] 3. Terrain adaptation structure: A perfect adaptation structure is designed for different complex terrains. The rubber cap 8 is made of high-elastic rubber material, which has good buffering performance and anti-skid effect, can effectively reduce the vibration to the hand when walking, and at the same time provides reliable grip on hard ground. The mud shoe 7 is designed to be detachable, connected to the top of the rubber cap 8 of the bottom of the stick through buckles or threads. When climbing snow mountains or crossing soft terrains such as deserts, the mud shoe 7 can be quickly installed to greatly increase the stress area of the trekking pole, prevent the pole from sinking into the snow or sand, and improve the stability and safety of walking. The extender 3 adopts a multi-section sleeve structure, which is locked and unlocked by a spring button 9, and can quickly adjust the length of the pole body according to the actual terrain and user's needs in a short time, ensuring the best support effect in various complex terrains.

[0082] 4. Convenient control system: The second mechanical button 15 is integrated at the lower end of the handle 1, designed as a convex type, easy to operate and not easy to be touched by mistake. The second mechanical button 15 is precisely connected with the internal mechanical transmission structure, and by pressing the "grab" button, the opening and closing of the mechanical arm 11 can be precisely controlled, and the second rotating shaft 12 can be flexibly rotated at multiple angles, which can easily clamp the protrusions on the rock wall, pick up fallen objects, etc.

[0083] 5. Tool maintenance design: The terrazzo crystal 2 is fixed by inlaying near the handle 1 of the pole body, and its surface is treated with special processing and contains high-efficiency abrasive ingredients. When the sickle 14 is worn out during use, it only needs to be attached to the surface of the terrazzo crystal 2, and through simple back-and-forth friction action, the blade can be quickly sharpened to restore its sharpness. This built-in sharpening design does not require carrying additional sharpening tools, and the sickle 14 can be maintained anytime and anywhere, effectively solving the problem of difficult maintenance of outdoor tools after wear and tear, reducing the use cost and prolonging the service life of the tool.

[0084] 6. Humanized auxiliary design: In addition to the ergonomic design and handprint grooves, the handle 1 is also covered with a layer of anti-slip and wear-resistant silicone material, further improving the comfort and stability of holding, even in the case of sweating hands or rainy and slippery conditions, it can ensure firm grip. The hanging handle 5 is made of high-strength nylon material, which has strong bearing capacity and can be used to hang small items such as keys, compasses, water bottles, etc., making it convenient for climbers to use at any time, while reducing the burden of backpacks. The pole body has a modular and detachable design, so when a component is damaged, the entire trekking pole does not need to be replaced, only the damaged component needs to be replaced, greatly reducing the maintenance cost and difficulty, and at the same time, users can easily configure and combine the trekking pole according to different use needs and scenarios.
