[0001] The present invention belongs to the technical field of hiking poles, and particularly relates to an outdoor device for driving away wild brown bears. Background Art

[0002] Chinese patent document with document number CN104585987A discloses a multifunctional hiking pole, including a handle and a pole body. The bottom end of the handle is connected to the top end of the pole body. The handle is hollow, and an A spray bottle and a B spray bottle are provided inside the handle. The top ends of the pressing parts of the A spray bottle and the B spray bottle are at the same height as the top end of the handle. The nozzles of the A spray bottle and the B spray bottle are on the same side of the handle and are both in communication with the atmosphere. The pole body is formed by connecting several sections of struts. The beneficial effects of the present invention are that when climbers climb mountains, they do not need to deliberately carry emergency medicine bottles. The A spray bottle and the B spray bottle can hold two kinds of emergency medicines, which can make climbers feel more secure when climbing mountains; the A spray bottle and the B spray bottle are arranged on the hiking pole, and climbers will not discard them after use, and it is also more convenient and fast when they need to use the medicine again; it has the advantages of simple structure and low processing cost.

[0003] Chinese patent document with document number CN204050225U discloses an electric spray walking stick, including a handle and a pole, and also including an electric spray device and a spray head. The electric spray device and the spray head are connected and both are installed in the pole. After adopting this technical solution, the walking stick can spray a misty liquid from the spray head through the built-in electric spray device, which can play a role in self-defense and expand the use of the walking stick.

[0004] During the use of the above patents, only manual operation can spray in one direction. When encountering a wild animal attack during mountain climbing, facing the animal attack directly is somewhat dangerous. It is a wiser choice to leave directly, but it is easy to be attacked by wild animals from behind. The above patents cannot meet the actual use requirements to a certain extent. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: aiming at the deficiencies existing in the prior art, to provide a hiking pole with the function of defending wild animals that can directly spray and can also be arranged on the ground to form a horizontal spray belt.

[0006] To achieve the purpose of the present invention, the following technical solutions are adopted: an outdoor device for driving away wild brown bears, including a main body component that can be used as a hiking pole and a switching component that can drive away and block bears and is arranged inside the main body component.

[0007] The main body assembly includes a main pipe body for the user to hold and a direct injection port provided at the upper part of the main pipe body; the switching assembly includes two winding pipes that are symmetrically arranged in the main pipe body and can extend to both sides and are wound into a roll shape, and a gas tank filled with bear repellent spray that is arranged in the main pipe body and can communicate with the direct injection port and the winding pipes respectively; a plurality of scattering ports communicating with the outside are formed on the inner wall of the winding pipe.

[0008] When the gas tank is communicated with the direct injection port, the high-pressure bear repellent spray in the gas tank can be directly sprayed through the direct injection port towards the wild brown bear for driving it away.

[0009] When the gas tank is communicated with the winding pipe, the high-pressure bear repellent spray in the gas tank first causes the winding pipe to unfold to both sides, and then the bear repellent spray is ejected through the scattering ports to form an isolation zone between the user and the wild brown bear to block the bear.

[0010] As a preferred solution: it further includes an adjustment assembly longitudinally slidably connected to the lower part of the main body assembly and a support assembly rotatably connected to the lower part of the adjustment assembly; the adjustment assembly includes a main seat body longitudinally slidably connected to the lower part of the main pipe body; the support assembly includes a secondary seat body rotatably connected to the lower end of the main seat body and two support rods rotatably connected to the secondary seat body and abutting against the ground; a plug post that can be inserted into the secondary seat body is slidably connected in the main seat body; an unlocking rod capable of driving the corresponding plug post to slide is formed at the lower part of the main pipe body.

[0011] When used as a hiking pole, the two support rods are located at the limit positions close to each other, the plug post is inserted into the secondary seat body, and the support assembly is located below the main pipe body.

[0012] When being stored, the main seat body slides upward, which can cause the unlocking rod to drive the plug post to slide until it is no longer inserted into the secondary seat body, and the support assembly can rotate upward to fit with the main pipe body.

[0013] As a preferred solution: a storage gear with the same rotation axis is formed on the secondary seat body; a fixed rack bar capable of being in transmission connection with the storage gear is formed at the lower part of the main pipe body; a first transmission gear rotatably connected to the main seat body and in transmission connection with each support rod is provided; the switching assembly further includes a sliding rack bar slidably connected to the lower part of the main pipe body and capable of being in transmission connection with the first transmission gear, and a limiting plate longitudinally slidably connected to the lower part of the main pipe body for driving the sliding rack to slide; the lower end of the unlocking rod is lower than the lower ends of the fixed rack and the sliding rack bar.

[0014] When the limit plate is in the first position, the sliding rack bar cannot contact the first transmission gear, the main seat body slides upward until it abuts against the lower end of the limit plate, and the fixed rack bar drives the secondary seat body to rotate until the support assembly fits against the main pipe body, thereby achieving storage.

[0015] When the limit plate is in the second position, the second position is lower than the first position, the sliding rack bar can be in transmission connection with the first transmission gear, the main seat body slides upward until it abuts against the lower end of the limit plate, and the sliding rack bar drives the support rod to rotate, such that an acute angle is formed between every two of the two support rods and the main pipe body, and the main body assembly can be placed on the ground.

[0016] As a preferred solution: further included is a control assembly rotatably connected to the upper part of the main pipe body; the control assembly includes an unlocking pipe rotatably connected to the upper part of the main pipe body, in transmission connection with the limit plate and capable of driving the limit plate to slide; two symmetrically arranged storage cavities for accommodating the extension pipes are formed on the outer wall of the main pipe body; a closing ring rotatably connected to the outer wall of the main pipe body and in transmission connection with the unlocking pipe is provided; a communication port capable of communicating with the storage cavity is formed on the outer wall of the closing ring.

[0017] When the limit plate is in the first position, the communication port is not in communication with the storage cavity; when the limit plate is in the second position, the communication port is in communication with the storage cavity.

[0018] As a preferred solution: a pressing nozzle for controlling the opening and closing of the gas tank and capable of communicating with the gas tank is slidably connected to the upper part of the gas tank; the switching assembly further includes a communication pipe fixedly connected to the pressing nozzle and a switching pipe in sealed rotational connection within the communication pipe and in communication with the pressing nozzle; two output pipes capable of respectively communicating with the switching pipe are formed on the outer wall of the communication pipe; the two output pipes are a first output pipe communicating with the direct injection port and a second output pipe communicating with the extension pipe; the unlocking pipe rotates synchronously to drive the switching pipe to rotate.

[0019] When the limit plate is in the first position, the switching pipe is not in communication with the output pipe; when the limit plate is in the second position, the switching pipe is in communication with the second output pipe.

[0020] As a preferred solution: the control component also includes a pressing column axially connected to the unlocking tube and abutting against the upper end of the switching tube, and a sliding column slidably connected to the pressing column along the diameter of the pressing column; the inner wall of the main tube is formed with an annular groove that can be slidably connected to the sliding column and is used to limit the sliding column from sliding downward; the inner wall of the main tube is formed with a lower sliding groove connected to the annular groove below the annular groove; the rotation of the unlocking tube drives the pressing column to rotate synchronously.

[0021] When the sliding post is facing the lower slide groove, the sliding post can slide downward along the lower slide groove, thereby enabling the pressing post to press the pressing nozzle. At this time, the switching tube is connected to the first output tube.

[0022] When the sliding post is not aligned with the lower sliding groove, the sliding post cannot slide downward.

[0023] As a preferred solution: a limit block is formed on the inner wall of the main body on the side away from the sliding groove to prevent the sliding column from sliding upward; the upper end of the limit block is formed with an inclined guide slope that can enable the sliding column to slide from the annular groove into the lower end of the limit block; an outward push spring is provided between the sliding column and the pressing column to make the sliding column slide in the direction away from the pressing column.

[0024] When the sliding column is facing the limiting block, the switching tube is communicated with the second output tube.

[0025] After the sliding post slides downward to the lower end of the limit block, the sliding post cannot slide upward, and the gas tank continues to output the bear repellent spray.

[0026] As a preferred solution: a locking tube with a radial opening at the lower end is fixedly connected to the outer wall of the main body; an inner rod slidingly connected to the locking tube is fixedly connected to the main seat body; a locking part capable of reducing the gap of the radial opening is installed at the lower end of the locking tube; the locking part includes an external pressure tube with a variable inner diameter arranged on the outer periphery of the locking tube and an eccentric lever rotatably connected to the outer wall of the external pressure tube and capable of changing the inner diameter of the external pressure tube.

[0027] As a preferred solution: the support assembly also includes a worm wheel rotatably connected to the sub-base body and transmission connected to each of the support rods, and a worm rotatably connected to the sub-base body, whose rotating shaft coincides with the rotating shaft of the sub-base body and is transmission connected to the worm wheel; the worm is transmission connected to the first transmission gear.

[0028] When the main base body slides upward, the fixed rack rod drives the auxiliary base body to rotate, and the sliding rack rod drives the first transmission gear to rotate. The worm and the auxiliary base body rotate in different directions.

[0029] As a preferred solution: The gas cylinder is rotatably connected within the main pipe body; a lead screw nut is fixedly connected to the upper end of the limit plate; a lead screw is fixedly connected to the lower end of the gas cylinder and is in transmission connection with the lead screw nut; a gas cylinder gear in transmission connection with the unlocking pipe is fixedly connected to the upper end of the gas cylinder.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows: In the initial state, the product is in a stored state, the main seat body is located at the extreme position close to the main pipe body; the two support rods are mutually attached, and the support assembly rotates upward to the extreme position; the sliding column is located between the position block and the lower chute and is not directly opposite to the limit block and the lower chute; the closing ring closes the storage cavity; the sliding rack bar is located at the extreme position away from the first transmission gear and does not contact the first transmission gear.

[0031] When the product is used as a hiking pole, the user holds the main pipe body with the hand and pulls the eccentric lever outwards, so that the outer pressure pipe no longer clamps the locking pipe, and the adjusting assembly can slide relative to the main body assembly. Then, the support assembly is rotated downward, that is, the secondary seat body rotates relative to the main seat body. The rotation of the secondary seat body will abut against the first unlocking slope and drive its movement, so that the insertion column slides away from the secondary seat body, and the locking spring is compressed and stores energy. When the secondary seat body rotates until the locking insertion hole is directly opposite to the insertion column, the insertion column slides towards the secondary seat body to the extreme position under the elastic force of the locking spring, and the insertion column is inserted into the locking insertion hole. Subsequently, the adjusting assembly is pulled downward so that the inner rod slides relative to the locking pipe, and the adjusting assembly is pulled out to a suitable distance so that the overall height is suitable for the user's height, and the eccentric lever is pulled back to the original position again. The eccentric rotation of the eccentric lever causes the outer pressure pipe to clamp the locking pipe, and the locking pipe clamps the inner rod, so that the adjusting assembly is relatively fixed to the main pipe body. When the user is hiking, using the hiking pole can reduce the exercise intensity.

[0032] If a wild animal, such as a brown bear, attacks while hiking, the user can quickly use this product to spray bear repellent spray and repel the bear. To use the bear repellent function, the user holds the upper portion of the main body with one hand, pointing the direct spray nozzle in the direction of the attack. With the other hand, turn the rotary dial forward, which rotates the unlocking tube. This rotation of the unlocking tube rotates the limiting slide, which in turn rotates the sliding post, which in turn rotates until it aligns with the lower slide groove, allowing the pressure post to slide downward relative to the unlocking tube. This rotation of the unlocking tube also rotates the driving hole, which in turn rotates the driven post, which in turn rotates the switching tube, which in turn rotates the switching hole. When the pressure post aligns with the lower slide groove, the switching tube rotates to connect only to the first output tube, connecting the switching tube to the direct spray nozzle. Then, press down on the pressure post. The downward movement of the pressure post drives the driven post downward, which in turn slides the switching tube downward, which in turn drives the connecting tube downward, which in turn drives the pressure spray nozzle downward. Press the nozzle to open the spray nozzle, and the high pressure inside the canister releases the bear repellent spray outward through the switching tube, the switching port, the first output tube, and the direct nozzle. This spray directly targets wild animals, such as brown bears, repelling them and giving the user ample time to evacuate.

[0033] After use, release the push rod. The spring inside the gas canister allows the push rod to slide upward to its original position, causing the switch tube to slide upward to its original position, and the slide rod to slide back into the annular groove. Reverse the rotation of the rotary dial to its original position, and the slide rod will rotate until it contacts the lower end of the inner wall of the annular groove, preventing it from sliding downward. This prevents accidental contact with the push rod while carrying or using a trekking pole, which could cause the bear repellent gas to leak.

[0034] When not in use, the user pulls the eccentric lever outward, causing the locking tube to no longer clamp onto the inner rod. The user then lifts the inner rod upward until the main body and the lower end of the limit plate abut against each other. The main body then slides upward, driving the locking post upward, which in turn causes the second unlocking bevel to abut against the unlocking lever. As the main body continues to slide upward, the unlocking lever drives the second unlocking bevel to slide, causing the locking post to slide away from the auxiliary body until it no longer engages with the locking socket, allowing the auxiliary body to rotate relative to the main body. As the main body continues to slide upward, the fixed rack rod pushes the auxiliary body downward, causing it to rotate relative to the main body. Simultaneously, the fixed rack rod is in transmission connection with the storage gear, causing the auxiliary body to slide upward, driving the storage gear to rotate, thus rotating the auxiliary body and the support rod upward. When the inner rod moves upward to its limit position, the support assembly rotates upward to its limit position. Subsequently, the eccentric lever is pulled back to its original position, securing the main body and the main body relative to each other, and the support assembly fits against the main body. The overall footprint is small, making it easy to carry.

[0035] When wild animals such as brown bears are found following during the transfer process, a barrier belt can be set up with this product to prevent the bear from following. When in use, the user rotates the rotating disk in the opposite direction to rotate the sliding column to face the limit block. The rotation of the rotating disk drives the switching tube to rotate so that the switching hole rotates to connect with the second output tube, that is, the switching hole is connected with the extension tube.

[0036] The rotation of the rotating disk drives the unlocking tube to rotate, thereby rotating the driving gear, and the rotation of the driving gear drives the transmission shaft to rotate. The rotation of the transmission shaft drives the inner ring gear to rotate, thereby rotating the closed ring, and the rotation of the closed ring drives the connecting port to rotate. When the sliding column rotates to face the limit block, the connecting port rotates to face the storage chamber. The rotation of the transmission shaft also drives the gas tank gear to rotate, causing the gas tank to rotate. The rotation of the gas tank drives the screw rod to rotate. The rotation of the screw rod causes the screw nut to slide downward under the guidance of the limit plate, that is, the limit plate slides downward. The downward sliding of the limit plate drives the propulsion column to slide downward, and the downward sliding of the propulsion column drives the inclined surface of the rack to slide, thereby causing the sliding rack rod to slide in the direction close to the first transmission gear to the extreme position, and the sliding rack rod can be connected to the first transmission gear.

[0037] Next, the eccentric lever is pulled outward, causing the locking tube to no longer clamp onto the inner rod. The main body is lifted until it contacts the lower end of the limit plate. Since the limit plate has slid downward a certain distance at this point, the fixed rack rod drives the storage gear to rotate at a reduced angle, preventing the support assembly from rotating until it aligns with the main body. Instead, a certain angle remains. During this process, the sub-body slides upward, driving the first transmission gear upward, thereby connecting the first transmission gear to the sliding rack rod. Simultaneously, the sliding rack rod drives the first transmission gear to rotate, which in turn drives the worm gear, which in turn rotates the worm. The worm rotates in the opposite direction of the sub-body. The rotation of the worm drives the worm wheel, which in turn rotates the face gear. The face gear rotates, which in turn drives the second transmission gear. The second transmission gear rotates the support gear, causing the two support rods to rotate away from each other.

[0038] Then, place the two support rods on the ground, and at the same time, position the storage chambers on the left and right sides. The support rods will firmly support the main body and prevent it from being covered. Press the pressing column to make the sliding column slide downward. The sliding column slides downward and slides away from the limit block under the guidance of the guide slope. The outward spring is compressed and stored. When the sliding column slides to the lower end of the limit block, the sliding column moves to its original position under the elastic force of the outward spring. The sliding column and the lower end of the limit block are against each other, and the sliding column cannot slide upward. The pressing nozzle is always in a pressed state. The bear repellent spray in the gas tank passes through the inside of the switching tube, the switching hole, the second output tube, and into the extension tube in sequence. The extension tube will expand to both sides under the action of the bear repellent spray pressure. At the same time, the bear repellent spray in the extension tube will be sprayed forward through the scattering port, forming a horizontal strip spray belt, which prevents wild animals such as brown bears from following and provides sufficient time for the user to escape.

[0039] The present invention is provided with support rods. When used as trekking poles, the two support rods fit together to support the user and reduce the intensity of exercise. When stored, the support rods rotate to fit together with the main body, reducing the occupied volume and making it possible to be carried around. When blocking a wild brown bear, the two support rods rotate away from each other and, after being placed on the ground, support the main body to prevent it from being covered, thereby ensuring that the extension tubes on the left and right sides can be placed horizontally between the wild brown bear and the user, forming a horizontal blocking zone, providing sufficient time for the user to escape.

[0040] The present invention provides a limit plate. When the limit plate is in the first position, the limit plate does not contact the sliding rack rod. When the main seat body slides upward to abut against the lower end of the limit plate, the support assembly can be rotated to fit with the main body, thereby accommodating the product and reducing the occupied volume; when the limit plate is in the second position, the second position is lower than the first position, and the limit plate pushes the sliding rack to be connected to the first transmission gear. When the main seat body slides upward to abut against the limit plate again, the sliding rack drives the first transmission gear to rotate, causing the two support rods to rotate, and finally, a stable triangular structure is formed between the two support rods and the main body, preventing the main body from being covered and ensuring the stability of the transverse barrier belt.

[0041] The present invention is provided with an unlocking tube. When the unlocking tube rotates, it can drive the switching tube to rotate, and then the switching tube is rotated to connect with the corresponding output tube, completing the pipeline switching. At the same time, the rotation of the unlocking tube can also drive the sliding column to rotate, so that the sliding column no longer abuts against the lower end of the inner wall of the annular groove. The sliding column can slide downward, the pressing nozzle can be pressed, and the bear repellent spray can be sprayed outward; at the same time, when blocking, it can also drive the closing ring to rotate, so that the storage chamber is no longer closed, and the extension tube can extend outward. Through one rotation, multiple movements are driven, which reduces the preparation time of the operation, responds quickly, and gains valuable time.

[0042] The present invention can be used as a hiking pole, and after being folded, it occupies a small space, making it convenient to carry and store; the present invention can spray bear repellent spray. During hiking, when encountering an attack by wild animals, it can quickly deploy a defense, reducing the preparation time; the present invention can also form a horizontal bear repellent spray barrier to prevent animals from trailing and buying sufficient time for escape.

[0071] When the limiting plate 44 is in the first position, the switching pipe 43 is not in communication with the output pipe 421; when the limiting plate 44 is in the second position, the switching pipe 43 is in communication with the second output pipe.

[0072] The control assembly 5 further includes a pressing column 52 that is axially slidably connected in the unlocking pipe 51 and abuts against the upper end of the switching pipe 43 and a sliding column 53 that is slidably connected to the pressing column 52 along the diameter of the pressing column 52; an annular groove 117 that can be slidably connected to the sliding column 53 and is used to limit the downward sliding of the sliding column 53 is formed on the inner wall of the main body 11; a downward sliding groove 115 that is in communication with the annular groove 117 is formed on the inner wall of the main body 11 below the annular groove 117; the unlocking pipe 51 rotates to drive the pressing column 52 to rotate synchronously.

[0073] A rotating disk 514 for rotating the unlocking pipe 51 is formed at the upper end of the unlocking pipe 51; a button hole is formed at the upper end of the rotating disk 514; a button part that is slidably connected to the button hole is formed at the upper end of the pressing column 52.

[0074] A limiting chute 513 which is slidably connected to the pressing post 52 is formed along the length direction on the outer wall of the unlocking tube 51; when the unlocking tube 51 rotates, the limiting chute 513 drives the pressing post 52 to rotate.

[0075] When the sliding post 53 is aligned with the lower chute 115, the sliding post 53 can slide downward along the lower chute 115, and thus the pressing post 52 can press the pressing nozzle 413. At this time, the switching tube 43 is communicated with the first output tube.

[0076] When the sliding post 53 is not aligned with the lower chute 115, the sliding post 53 cannot slide downward, preventing the accidental touch from causing the leakage of the bear repellent spray.

[0077] A limiting block 114 for preventing the sliding post 53 from sliding upward is formed on the inner wall of the main pipe body 11 on the side far from the lower chute 115; an inclined guiding slope 1141 is formed at the upper end of the limiting block 114, which can make the sliding post 53 slide from the annular groove 117 into the lower end of the limiting block 114; an external pushing spring 54 for making the sliding post 53 slide away from the pressing post 52 is arranged between the sliding post 53 and the pressing post 52.

[0078] When the sliding post 53 is aligned with the limiting block 114, the switching tube 43 is communicated with the second output tube.

[0079] After the sliding post 53 slides downward to the lower end of the limiting block 114, the sliding post 53 cannot slide upward, and the gas tank 41 continuously outputs the bear repellent spray outward.

[0080] Two symmetrically arranged locking tubes 113 with radial openings at the lower ends are fixedly connected to the outer wall of the main pipe body 11; two symmetrically arranged inner rods 22 which are respectively slidably connected to the locking tubes 113 are fixedly connected to the main seat body 21; a locking part for reducing the gap of the radial opening is installed at the lower end of the locking tube 113; the locking part includes an outer pressure tube 131 with a variable inner diameter arranged on the outer periphery of the locking tube 113 and an eccentric lever 133 which is rotatably connected to the outer wall of the outer pressure tube 131 and can change the inner diameter of the outer pressure tube 131.

[0082] The support assembly 3 further includes a worm gear 34 rotatably connected in the secondary seat body 31 and drivingly connected to each support rod 32, and a worm 35 rotatably connected to the secondary seat body 31 with the rotation axis of the worm 35 coinciding with the rotation axis of the secondary seat body 31 and drivingly connected to the worm gear 34; the worm 35 is drivingly connected to the first transmission gear 25.

[0083] A second transmission gear 33 rotatably connected in the secondary seat body 31 and drivingly connected to one support gear 321; an end face gear 341 drivingly connected to the second transmission gear 33 is formed at one end of the worm gear 34 close to the support rod 32; a worm gear 351 drivingly connected to the first transmission gear 25 is fixedly connected to the central position of one end of the worm 35.

[0084] When the main seat body 21 slides upward, the fixed rack bar 112 drives the secondary seat body 31 to rotate, the sliding rack bar 45 drives the first transmission gear 25 to rotate, and the rotation direction of the worm 35 is different from that of the secondary seat body 31.

[0085] The gas tank 41 is rotatably connected in the main pipe body 11; a lead screw nut 442 is fixedly connected to the upper end of the limit plate 44; a lead screw 411 drivingly connected to the lead screw nut 442 is fixedly connected to the lower end of the gas tank 41; a gas tank gear 412 drivingly connected to the unlocking tube 51 is fixedly connected to the upper end of the gas tank 41.

[0086] A transmission shaft 46 with both ends drivingly connected to the gas tank gear 412 and the unlocking tube 51 respectively is rotatably connected in the main pipe body 11; a plurality of anti-rotation holes 441 are formed on the limit plate 44; the anti-rotation holes 441 are respectively slidably connected to the corresponding unlocking rods 111 and the fixed rack bar 112.

[0087] The direct injection port 119 has the same orientation as the scattering holes, and a strong light lamp is further provided on the main pipe body 11; the strong light lamp has the same orientation as the direct injection port 119 and the scattering holes; when the pressing column 52 is pressed, while spraying the bear repellent spray, strong light is emitted to drive away wild brown bears, etc.

[0088] In the initial state, the product is in a stored state. The main seat body 21 is located at the limit position close to the main pipe body 11; the two support rods 32 are attached to each other, and the support assembly 3 rotates upward to the limit position; the sliding column 53 is located between the position block 114 and the lower chute 115 and is not directly opposite to the limit block 114 and the lower chute 115; the closing ring 12 closes the storage cavity 118; the sliding rack bar 45 is located at the limit position far from the first transmission gear 25, and the sliding rack bar 45 does not contact the first transmission gear 25.

[0089] When the product is used as a hiking pole, the user holds the main pipe body 11 with the hand and pulls the eccentric lever 133 outward, so that the outer pressure pipe 131 no longer clamps the locking pipe 113, and the adjusting assembly 2 can slide relative to the main body assembly 1. Then, the support assembly 3 is rotated downward, that is, the secondary seat body 31 rotates relative to the main seat body 21. The rotation of the secondary seat body 31 will abut against and drive the first unlocking slope 231 to move, so that the insertion post 23 slides away from the secondary seat body 31, and the locking spring 24 is compressed and stores energy. When the secondary seat body 31 rotates until the locking socket 312 is directly opposite to the insertion post 23, the insertion post 23 slides to the limit position relative to the secondary seat body 31 under the elastic force of the locking spring 24, and the insertion post 23 is inserted into the locking socket 312. Subsequently, the adjusting assembly 2 is pulled downward so that the inner rod 22 slides relative to the locking pipe 113, and the adjusting assembly 2 is pulled out to a suitable distance so that the overall height is suitable for the user's height. Then, the eccentric lever 133 is pulled back to its original position. The eccentric rotation of the eccentric lever 133 causes the outer pressure pipe 131 to clamp the locking pipe 113, and the locking pipe 113 clamps the inner rod 22, so that the adjusting assembly 2 is relatively fixed to the main pipe body 11. When the user is hiking, the hiking pole is used to reduce the exercise intensity.

[0090] When encountering an attack by wild animals such as wild brown bears during mountain climbing, the user can quickly use this product to spray bear repellent spray to drive away the bear. When using the bear repellent function, the user holds the upper part of the main tube body 11 with the hand, and at the same time makes the direct spray port 119 face the attack direction. The other hand rotates the rotary disk 514 clockwise, that is, makes the unlocking tube 51 rotate. The rotation of the unlocking tube 51 drives the limit sliding groove 513 to rotate, and the rotation of the limit sliding groove 513 drives the sliding column 53 to rotate, so that the sliding column 53 rotates to be aligned with the lower sliding groove 115, and the pressing column 52 can slide downward relative to the unlocking tube 51. At the same time as the unlocking tube 51 rotates, it drives the driving hole 511 to rotate, and the rotation of the driving hole 511 drives the driven column 431 to rotate, so that the switching tube 43 rotates. The rotation of the switching tube 43 drives the switching hole 432 to rotate. When the pressing column 52 rotates to be aligned with the lower sliding groove 115, the switching tube 43 rotates to be only communicated with the first output tube 421, that is, at this time the switching tube 43 is communicated with the direct spray port 119. Then press down the pressing column 52, and the downward sliding of the pressing column 52 drives the driven column 431 to slide downward, so that the switching tube 43 slides downward. The downward sliding of the switching tube 43 drives the connecting tube 42 to slide downward, and the downward sliding of the connecting tube 42 drives the pressing nozzle 413 to slide downward. The pressing nozzle 413 opens, and the bear repellent spray in the gas tank 41 is sprayed outwards under the high pressure in the tank in turn through the inside of the switching tube 43, the switching hole 432, the first output tube, and the direct spray port 119. The bear repellent spray is directly sprayed on wild animals such as wild brown bears, driving them away and providing sufficient time for the user to transfer.

[0091] After use, release the pressing column 52, and the pressing nozzle 413 slides upward to its original position under the action of the spring in the gas tank 41. At the same time, the switching tube 43 slides upward to its original position, and the sliding column 53 slides back into the annular groove 117. Rotate the rotary disk 514 counterclockwise to its original position, and the sliding column 53 rotates to abut against the lower end inner wall of the annular groove 117, so that the sliding column 53 cannot slide downward, avoiding accidental contact with the pressing column 52 during the process of carrying or using the hiking pole, resulting in leakage of the bear repellent gas.

[0092] When not in use, the user pulls the eccentric lever 133 outward, so that the locking tube 113 no longer clamps the inner rod 22. The user then lifts the inner rod 22 upward until the main seat body 21 abuts against the lower end of the limit plate 44. The upward sliding of the main seat body 21 drives the insertion post 23 to slide upward, and then the second unlocking slope 232 abuts against the unlocking rod 111. As the main seat body 21 continues to slide upward, the unlocking rod 111 drives the second unlocking slope 232 to slide, causing the insertion post 32 to slide away from the sub-seat body 31 until it no longer engages with the locking socket 312, and the sub-seat body 31 can rotate relative to the main seat body 21. As the main seat body 21 continues to slide upward, the fixed rack bar 112 will push the sub-seat body 31 downward, causing the sub-seat body 31 to rotate relative to the main seat body 21. At the same time, the fixed rack bar 112 is in transmission connection with the receiving gear 311. The upward sliding of the sub-seat body 31 causes the fixed rack bar 112 to drive the receiving gear 311 to rotate, that is, to rotate the sub-seat body 31, and the support rod 32 rotates upward. When the inner rod 22 moves upward to the limit position, the support assembly 3 rotates upward to the limit position. Subsequently, the eccentric lever 133 is pulled back to its original position, so that the main seat body 21 is fixed relative to the main pipe body 11, and the support assembly 3 fits against the main pipe body 11. The overall space occupied is small and it is convenient to carry around.

[0093] When it is found that wild animals such as wild brown bears are following during the transfer process, the user can also set up a blocking belt through this product to block the bear from following. When in use, the user reversely rotates the rotating disk 514 so that the sliding column 53 rotates to be directly opposite to the limit block 114. The rotation of the rotating disk 514 drives the switching tube 43 to rotate, causing the switching hole 432 to rotate to communicate with the second output tube, that is, the switching hole 432 communicates with the extension tube 47.

[0094] The rotation of the rotating disk 514 drives the unlocking tube 51 to rotate, which in turn causes the driving gear 512 to rotate. The rotation of the driving gear 512 drives the transmission shaft 46 to rotate. The rotation of the transmission shaft 46 drives the inner ring gear 122 to rotate, which in turn causes the closing ring 12 to rotate. The rotation of the closing ring 12 drives the communication port 121 to rotate. When the sliding column 53 rotates to be directly opposite to the limit block 114, the communication port 121 rotates to be directly opposite to the receiving cavity 118. The rotation of the transmission shaft 46 also drives the gas tank gear 412 to rotate, causing the gas tank 41 to rotate. The rotation of the gas tank 41 drives the lead screw 411 to rotate. The rotation of the lead screw 411 causes the lead screw nut 442 to slide downward under the guiding action, that is, to make the limit plate 44 slide downward. The downward sliding of the limit plate 44 drives the push column 443 to slide downward. The downward sliding of the push column 443 drives the rack slope 451 to slide, and then the sliding rack bar 45 slides toward the first transmission gear 25 to the limit position, and the sliding rack bar 45 can be in transmission connection with the first transmission gear 25.

[0095] Next, pull the eccentric lever 133 outward so that the locking tube 113 no longer clamps the inner rod 22. Lift the main seat body 21 upward until it abuts against the lower end of the limit plate 44. Since the limit plate 44 has slid downward by a certain distance at this time, that is, the fixed rack bar 112 drives the receiving gear 311 to rotate by a smaller angle, and the support assembly 3 cannot rotate to fit with the main pipe body 11, but there is a certain included angle. During this process, the secondary seat body 31 slides upward and drives the first transmission gear 25 to slide upward, so that the first transmission gear 25 is in transmission connection with the sliding rack bar 45. At the same time, the sliding rack bar 45 drives the first transmission gear 25 to rotate, and the first transmission gear drives the worm gear 351 to rotate, thereby causing the worm 35 to rotate. The rotation direction of the worm 35 is opposite to the rotation direction of the secondary seat body 31. The rotation of the worm 35 drives the worm wheel 34 to rotate, thereby causing the end face gear 341 to rotate. The rotation of the end face gear 341 drives the second transmission gear 33 to rotate, and the rotation of the second transmission gear 33 drives the support gear 321 to rotate, so that the two support rods 32 rotate in a direction away from each other.

[0096] Subsequently, place the two support rods 32 on the ground, and at the same time make the receiving cavity 118 located on the left and right sides. The support rods 32 will firmly support the main pipe body 11 so that it cannot tip over. Press the pressing column 52 so that the sliding column 53 slides downward. Under the guiding action of the guiding inclined surface 1141, the sliding column 53 slides away from the limit block 114, and the outer pushing spring 54 is compressed and stores energy. When the sliding column 53 slides to the lower end of the limit block 114, the sliding column 53 moves to its original position under the elastic force of the outer pushing spring 54 and abuts against the lower end of the limit block 114, and the sliding column 53 cannot slide upward. The pressing nozzle 413 is always in a pressed state. The bear repellent spray in the gas tank 41 sequentially passes through the inside of the switching pipe 43, the switching hole 432, the second output pipe, and enters the extension pipe 47. Under the action of the pressure of the bear repellent spray, the extension pipe 47 will expand to both sides. At the same time, the bear repellent spray in the extension pipe 47 is sprayed forward through the scattering port, forming a horizontally arranged strip-shaped spray band to block the trailing of wild animals such as brown bears and provide sufficient time for the user to escape.

[0097] By providing the support rods 32, when the present invention is used as a hiking pole, the two support rods 32 are attached to each other to support the user, reducing the exercise intensity. When being stored, the support rods 32 rotate to fit with the main pipe body 11, reducing the occupied volume and being able to be carried around. When blocking wild brown bears, the two support rods 32 rotate in a direction away from each other. After being placed on the ground, they support the main pipe body 11 to prevent it from tipping over, thereby ensuring that the extension pipes 47 on both sides can be horizontally placed between the wild brown bear and the user, forming a horizontal blocking band and providing sufficient time for the user to escape.

[0098] In the present invention, by providing a limiting plate 44, when the limiting plate 44 is in the first position, the limiting plate 44 does not contact the sliding rack rod 45. When the main seat body 21 slides upward until it abuts against the lower end of the limiting plate 44, the support assembly 3 can rotate to fit with the main pipe body 11, thereby storing the product and reducing the occupied volume. When the limiting plate 44 is in the second position, the second position is lower than the first position. The limiting plate 44 can push the sliding rack 45 to be in driving connection with the first transmission gear 25. When the main seat body 21 slides upward until it abuts against the limiting plate 44 again, the sliding rack 45 drives the first transmission gear 25 to rotate, causing the two support rods 32 to rotate. Eventually, a stable triangular structure is formed between the two support rods 32 and the main pipe body 11 in pairs, preventing the main pipe body 11 from tipping over and ensuring the stability of the horizontal blocking belt.

[0099] In the present invention, by providing an unlocking pipe 51, when the unlocking pipe 51 rotates, it can drive the switching pipe 43 to rotate. Furthermore, the switching pipe 43 can be rotated to communicate with the corresponding output pipe 421, completing the pipeline switching. At the same time, when the unlocking pipe 51 rotates, it can also drive the sliding column 53 to rotate, so that the sliding column 53 no longer abuts against the lower end inner wall of the annular groove 117. The sliding column 53 can slide downward, and the pressing nozzle 413 can be pressed down, and the bear repellent spray can be ejected outward. At the same time, when carrying out the blocking, it can also drive the closing ring 12 to rotate, so that the storage cavity 118 is no longer closed, and the extension pipe 47 can extend outward. By one rotation, multiple movements are driven, reducing the preparation time of the operation, with a rapid response and precious time saved.

[0100] The present invention can be used as a hiking pole. After being stored, it occupies a small space and is convenient to carry and store. The present invention can spray bear repellent spray. During the hiking and mountain climbing process, when encountering an attack by wild animals, it can quickly deploy a defense, reducing the preparation time. The present invention can also form a horizontal bear repellent spray blocking belt to prevent animals from following and gain sufficient time for escape.
