[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 2 , Figure 4, the utility model provides an embodiment: a novel insect hole injection device for controlling stem borers, including a box body 1, the medicine can be placed inside the box body 1, and then the medicine on the inner wall of the box body 1 is processed and sent out through the pump body on the top of the box body 1, and the medicine is sent out through the connecting pipe 1 21, the connecting pipe 2 23 and the nozzle 32. The process of adding medicine inside the box body 1 and the pump body arranged thereon are both existing technologies and can be implemented by technicians in this field, so they will not be described in detail in this case. A winding component is arranged on the front surface of the box body 1, and a medicine injection component is arranged on the upper surface of the winding component. The winding component includes a fixed block 22 for ensuring the stable rotation of the cylindrical tube 24, and the fixed block 22 is fixedly connected to the rear surface of the box body 1. The left surface of the fixed block 22 is penetrated by a cylindrical tube 24 that is rotatably connected, and the connecting tube 23 can be rolled up by rotating the cylindrical tube 24. The lower surface of the right end of the cylindrical tube 24 is penetrated by a connecting tube 23 that is fixedly connected. The inner wall of the left end of the cylindrical tube 24 is rotatably connected to a connecting block 211 to prevent the connecting tube 23 from rotating along with the cylindrical tube 24. The right surface of the connecting block 211 is fixedly connected to the left surface of the fixed block 22, and the left surface of the connecting block 211 is penetrated by a connecting tube 1 21 that is fixedly connected. The medicine inside the box body 1 can be delivered into the inner wall of the cylindrical tube 24 through the connecting tube 1 21, and then the medicine enters the interior of the connecting tube 23. The rear surface of the top end of the connecting tube 1 21 is arranged on the front surface of the top end of the box body 1.

[0032] Reference Figure 1 , Figure 3 The injection component includes a telescopic tube 31, which is a prior art. The telescopic tube 31 is a prior art, which is composed of multiple groups of sleeves. The connection distance of the multiple groups of sleeves can be adjusted at will, and it can be achieved by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The telescopic tube 31 slides on the inner wall of the left end of the connecting tube 23. The upper surface of the telescopic tube 31 contacts the nozzle 32, and the lower surface of the nozzle 32 is fixedly connected to a connecting column 34. The outer wall of the connecting column 34 is provided with a rubber ring to ensure that when it is inserted into the inner wall of the top end of the telescopic tube 31, the rubber ring will be squeezed and deformed to make the connection more stable. The connecting column 34 is plugged into the inner wall of the top end of the telescopic tube 31, and the lower surface of the connecting column 34 is fixedly connected to a connecting head 33. When the connecting tube 23 is sleeved on the outer wall of the connecting head 33, it can be reinforced with iron wire or thin rope to ensure the stability of the installation of the connecting tube 23. The outer wall of the bottom end of the connecting head 33 is plugged into the inner wall of the top right side of the connecting tube 23.

[0033] Reference Figure 2 , Figure 5The winding assembly also includes a round rod 212, the left surface of the round rod 212 is fixedly connected to the right surface of the cylindrical tube 24, the outer wall of the round rod 212 is slidably connected with a round plate 25, and the movable round plate 25 can drive the limiting rod 26 to move stably. The front surface of the round plate 25 is penetrated by a pull plate 27 that is slidably connected, and the front surface of the round rod 212 is provided with a groove 210. When the circular plate 25 is moved, the limiting rod 26 is separated from the inner wall of the groove 1 28, and the rear side of the left end of the pull plate 27 can be inserted into the inner wall of the groove 210 to limit the circular plate 25, so that the circular plate 25 can be ensured. When the operator rotates the cylindrical tube 24, there is no need to continuously pull the circular plate 25, which improves practicality. The rear surface of the right end of the pull plate 27 contacts the inner wall of the groove 210, and the pull plate 27 and the inner wall of the groove 210 are interference fit to ensure the stability of the limit. A spring 29 is sleeved on the outer wall of the round rod 212. The spring 29 always pushes the circular plate 25 to move to the left through its own elasticity to ensure the stability of the limit rod 26. One end of the spring 29 is fixedly connected to the right surface of the circular plate 25, and the other end of the spring 29 is fixedly connected to the left surface of the round rod 212.

[0034] Reference Figure 1 - Figure 2 , Figure 5 There are multiple groups of fixed blocks 22, and the multiple groups of fixed blocks 22 are arranged to ensure the stability of the rotation of the cylindrical tube 24. The rear surfaces of the multiple groups of fixed blocks 22 are fixedly connected to the front surface of the box body 1 adjacent to the right side of the fixed blocks 22. The inner walls of the multiple groups of fixed blocks 22 are slidably connected to the outer wall of the right end of the cylindrical tube 24. A groove 28 is opened on the right surface of the multiple groups of fixed blocks 22. A limiting rod 26 for limiting the cylindrical tube 24 is fixedly connected to the left surface of the circular plate 25, and the left surface of the limiting rod 26 contacts the inner wall of the groove 28.

[0035] Working principle: When the telescopic tube 31 is retracted, the connecting tube 23 will be too long. At this time, by pulling the pull plate 27, the circular plate 25 moves to the right, the limiting rod 26 is separated from the inner wall of the groove 1 28, and then the cylindrical tube 24 is rotated to reel in the excess connecting tube 23. After the reeling is completed, the pull plate 27 is released, and the spring 29 pushes the circular plate 25 to move to the left, so that the limiting rod 26 is inserted into the groove 1 28, and the cylindrical tube 24 is limited to ensure that the reeled connecting tube 23 is 3, when it is necessary to extend the telescopic tube 31, the above operation can be repeated to disengage the limit rod 26 from the inner wall of the groove 1 28, and then insert the rear side of the left end of the pull plate 27 into the inner wall of the groove 210. At this time, when the length of the telescopic tube 31 is extended, the connecting tube 23 wrapped around the outer wall of the cylindrical tube 24 will be pulled out and drive the cylindrical tube 24 to rotate. After the adjustment is completed, the pull plate 27 is pulled out from the inner wall of the groove 210 and the hand can be released.

[0036] When the nozzle 32 is worn, clogged or damaged, the connecting column 34 can be pulled out from the inner wall of the top of the telescopic tube 31 and replaced with a new nozzle 32 without replacing the entire telescopic nozzle, thereby saving costs and extending the service life of the injection device.

[0037] The specific drug injection operation is to adjust the length of the telescopic tube 31 according to the height of the wormhole, and send the medicine on the inner wall of the box body 1 out through the pump body on the top of the box body 1. The medicine passes through the connecting tube 1 21 and enters the inner wall of the cylindrical tube 24, and then enters the inside of the connecting tube 2 23. The medicine passes through the connecting tube 2 23 and the connecting head 33, and is finally sprayed out from the nozzle 32 to inject the medicine into the wormhole.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
