[0002] Wasps, a social insect, are known for their intense territoriality and aggressive nature. When they sense a threat, they will attack without hesitation. Even more worryingly, the venom of some wasps is extremely lethal, capable of sending adults into shock or even killing them. In recent years, the increasing number of wasp populations has necessitated the urgent task of removing wasp nests in more and more areas.

[0003] The locations where wasp nests are built are often a headache. They prefer tall trees or the eaves of buildings. These places are not only difficult to access, but also pose a huge challenge to the removal work. During the removal process, in addition to dealing with the sturdy nest itself, there are also a large number of adult bees wandering around the nest, and these adult bees also need to be effectively controlled. The current practice is to use fire to eliminate adult bees, but because their nests are built in high positions, it is not effective to reach the location by simply using handheld methods, and it is inconvenient to use bamboo poles or other methods to bind firearms. Therefore, it is difficult to remove adult bees. Therefore, according to the existing situation, it is necessary to design a tool for the subject of wasp removal that is convenient for removing wasps. Summary of the Invention

[0029] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0030] like Figure 1-5 As shown, the specific solution of this embodiment is: a handheld device for removing a hornet's nest, comprising a plurality of telescopic rods 10 that are telescopically arranged, and a locking button 34 that fixes two sections to each other is provided between the plurality of telescopic rods 10, as shown in FIG. Figure 1A plurality of through-holes are provided on the telescopic rod 10, and the locking button 34 is inserted into the through-hole to realize the locking between the two telescopic rods 10. A support seat 11 is fixedly provided at the end of the telescopic rod 10. The support seat 11 and the end of the telescopic rod 10 are fixed by welding or screws. A clamping seat 12 is provided on the support seat 11. The specific clamping seat 12 is two "C"-shaped structures, which are fixed by bolts. A gas cylinder 13 is detachably provided on the clamping seat 12. The gas cylinder 13 can be filled with high-pressure gas or high-pressure insecticide purchased outside.

[0031] A pressing member 14 is hingedly provided on the support base 11 to press the gas cylinder 13. Figure 1 As shown, the pressing member 14 is an "L"-shaped pressure rod, and a handle 19 is provided on the end of the telescopic rod 10 away from the support seat 11. A self-rebounding torsion spring is provided on the handle 19. A first pull rod 20 is connected to the handle 19, and a second pull rod 21 is connected to the pressing member 14. The second pull rod 21 and the first pull rod 20 are mutually transmitted and drive the pressing member 14 to press the gas cylinder 13 to spray fuel. That is, when the handle 19 is pressed, the first pull rod 20 and the second pull rod 21 can be synchronously driven to retract backward, thereby pulling the pressing member 14 to press the gas cylinder 13 downward to spray the fuel.

[0032] The clamping seat 12 is provided with an ignition device 15 for igniting the fuel sprayed from the gas cylinder 13. Specifically, a support rod is also welded to the clamping seat 12, which is arranged vertically upward and inclined in the direction away from the gas cylinder 13. The ignition device 15 is arranged on the top of the support rod, facing the injection port of the gas cylinder 13. The ignition device 15 is an electrically driven igniter; a controller 16 is fixedly provided on the telescopic rod 10, and the controller 16 contains a control chip and a battery. The controller 16 is interconnected with the ignition device 15 through a cable 17; the controller 16 is also remotely connected to a remote control 18 for controlling its ignition. Specifically, the remote control 18 and the controller 16 are connected by wireless Bluetooth. When the ignition button of the remote control 18 is pressed, the signal can be transmitted to the control chip of the controller 16, thereby controlling the battery to energize the ignition device 15 to achieve ignition.

[0033] According to the introduction of the solution of the present application, it can be clearly seen that the solution of the present application can be achieved by stretching the telescopic rod 10 and pressing the handle 19. The handle 19 will drive the pressing part 14 to press the gas cylinder 13 to spray fuel. At this time, pressing the remote control 18 can remotely energize and ignite the ignition device 15, thereby spraying fire to eliminate the hornets located at a high place. It is suitable for removing nests at different heights, can be portable and adjusted in length, is easy to operate, and protects the safety of firefighters.

[0034] As a preferred embodiment of the above embodiment, in order to realize the downward control of the pressing piece 14 after the telescopic rod 10 is extended and lengthened, a transmission device is set for control. The transmission device is used to link the handle 19 and the pressing piece 14, so that when the handle 19 is pressed, the pressing piece 14 is synchronously driven to press the gas cylinder 13 downward. The transmission device includes an electric push rod control. The specific solution is that the first pull rod 20 is connected to the control switch, and the second pull rod 21 is connected to the electric push rod. The electric push rod is arranged inside the telescopic rod 10. The control switch and the electric push rod are connected by an electric wire, and can be powered by the battery in the controller 16, or by another external power supply. Therefore, when the handle 19 is pressed to energize the electric push rod, the electric push rod will pull the pressing piece 14 to press the gas cylinder 13 downward, change the extension direction of the electric push rod, and realize the rebound of the pressing piece 14.

[0035] In addition, the present application also provides another structure of a transmission device. Specifically, the first pull rod 20 and the second pull rod 21 are respectively extended into the interior of the telescopic rod 10, and an elastic rope 35 (such as a spring) that drives the second pull rod 21 to rebound is connected between the second pull rod 21 and the inner wall of the telescopic rod 10. Figure 2 ), and the first pull rod 20 is connected to the first rack rod 22, the second pull rod 21 is connected to the second rack rod 23, and the transmission device is arranged between the first rack rod 22 and the second rack rod 23; refer to the attached Figure 3 ; The transmission device includes a socket seat 24 that is simultaneously socketed with the first rack bar 22 and the second rack bar 23. The socket seat 24 slides with the first rack bar 22 and the second rack bar 23 and has a certain friction force. A gear 25 is provided in the socket seat 24, which is respectively meshed with the first rack bar 22 and the second rack bar 23. A slide groove 27 is provided on the socket seat 24, and a movable seat 26 that can slide along the slide groove 27 is rotatably provided on the rotating shaft of the gear 25; an outwardly protruding stop pin 28 is provided on the outer side of the socket seat 24, and the stop pin 28 is close to the side edge of the slide groove 27. The stop pin 28 can contact the shift rod set on the rotating shaft of the gear 25 after the movable seat 26 approaches. The stop pin 28 mainly serves to block the shift rod to prevent the gear 25 from rotating.

[0036] Furthermore, in order to prevent the stop pin 28 from frequently contacting and blocking the shift rod, a guide rail 30 is provided on the outer wall of the socket 24 to guide the movement of the movable seat 26, and a spring piece 29 is provided on the guide rail 30. The spring piece 29 can contact the side of the movable seat 26 and only play a blocking role on the movable seat 26 when the squeezing force of the movable seat 26 on the spring piece 29 is small. Therefore, when the movable seat 26 is released with a smaller squeezing force and the spring piece 29, the shift rod will not contact the stop pin 28, so that the gear 25 can rotate normally.

[0037] Regarding the transmission device, it is mainly to be able to adapt to the changes in the telescopic lengths between several telescopic rods 10. For example, in the present application, when the telescopic rod 10 is pulled to extend, in the transmission device, the first rack rod 22 and the second rack rod 23 will respectively be subjected to the pulling force from the two ends, thereby being able to smoothly drive the gear 25 to rotate and adapt to the changes in the extension of the telescopic rod 10; and when it is necessary to control the downward action of the pressing member 14 by pressing the handle 19, the handle 19 first drives the first pull rod 20 and the first rack rod 22 to move backward, and the specific setting direction of the handle 19 side is the rear side. At this time, the first rack rod 22 will drive the gear 25 to rotate, but because the second rack rod 23 has friction with the socket 24 at this time and cannot move forward, it can only drive the gear 25 in the first position. The second rack rod 23 rolls backward until the movable seat 26 completely squeezes the spring piece 29 and the stop pin 28 blocks the stop rod, and the gear 25 cannot rotate and roll. At this time, the gear 25 becomes a connecting block connecting the first rack rod 22 and the second rack rod 23, which can synchronously pull the first rack rod 22, the gear 25, the second rack rod 23 and the socket seat 24 to move backward together as a whole, thereby controlling the pressing piece 14 to swing down and press the gas cylinder 13 to spray fuel to achieve ignition; after releasing the handle 19, due to the pushing action of the torsion spring inside it, the first rack rod 22 can push the gear 25 to move forward, causing the gear 25 to rotate in the opposite direction away from the stop pin 28 and to rotate again, thereby releasing the locking and synchronous movement of the first rack rod 22 and the second rack rod 23 by the gear 25.

[0038] As a preferred embodiment of the above embodiment, in order to control the rebound of the pressing member 14 after the handle 19 is released, a limiting seat 31 is movably provided on the outer side of the sleeve seat 24, and a return spring 32 for pulling the sleeve seat 24 is provided between the limiting seat 31 and the sleeve seat 24. The return spring 32 provides elastic tension when the sleeve seat 24 moves toward the rear side. Therefore, after the handle 19 is released, the first rack bar 22 will move forward, thereby realizing unlocking between the second rack bar 23 and the gear 25. Under the pull of the return spring 32, the sleeve seat 24 moves forward, and the second rack bar 23 can move forward together with the second pull rod 21 under the pull of the elastic rope 35, thereby controlling the rebound of the pressing member 14.

[0039] Both ends of the limiting seat 31 are further provided with retaining rings 33 for limiting the range of movement of the sleeve seat 24 . The retaining rings 33 are threadedly connected to the inner side of the limiting seat 31 to limit the range of movement of the sleeve seat 24 .

Specific examples are used herein to illustrate the principles and implementation methods of the technical solution of the present invention. The above examples are only used to help understand the method of the present invention and its core idea. The above is only a preferred embodiment of the present invention. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should all be regarded as the scope of protection of the present invention.
