[0024] As Figures 1 to 6As shown, the housing barrel 107 is fixedly installed with a folding sleeve 108 away from the main motor 103, the folding sleeve 108 is made of flexible material to protect the lower shaft 302, the folding sleeve 108 is fixedly installed with a flexible ring 109 away from the housing barrel 107, the flexible ring 109 is used to position the drilling position of the device, the folding sleeve 108 and the flexible ring 109 can also collect the debris splashed out when the drill rod drills trees, prevent the debris from splashing and protect the user's safety, the end of the housing barrel 107 provided with the folding sleeve 108 is fixedly installed with a compression rod 304, the compression rod 304 is provided with a plurality of extension springs, the plurality of extension springs are used to make the compression rod 304 shrink and return to the initial state, the end of the compression rod 304 away from the housing barrel 107 is fixedly installed with a positioning ring 305, the diameter of the positioning ring 305 is larger than that of the lower shaft 302, the positioning ring 305 is used to protect the conical drill bit 306 from being collided, the flexible ring 109 is fixedly installed with a measuring rod 110, the measuring rod 110 is arranged outside the folding sleeve 108, the measuring rod 110 is provided with a plurality of measuring scales, the folding sleeve 108 can be observed through the measuring rod 110 after folding, which is used to facilitate the user to observe the drilling depth.

[0025] When the device is used, the liquid medicine is directly poured into the liquid storage tank 105, and the liquid medicine in the liquid storage tank 105 also flows into the booster chamber during use, then the user closes the liquid storage tank 105 through the sealing cover 106, at this time the device completes the preparation before drug administration, then the user holds the handle 102, aligns the flexible ring 109 with the positioning ring 305 at the position where the drug is administered, then starts the main motor 103, changes the torque and rotating speed of the power output by the main motor 103 through the torque gearbox 201, drives the lower shaft 302 to rotate after the output shaft of the torque gearbox 201 passes through the upper main shaft 301, when the lower shaft 302 rotates, the user presses the device to move the device to the center of the tree, at this time the lower shaft 302 will punch the tree through the conical drill bit 306 and the drill rod, and the wood chips discharged by the drill rod will be collected by the folding sleeve 108 to prevent splashing, the protruding drill teeth 307 on the conical drill bit 306 will also have the effect of assisting drilling when the device drills into the tree trunk, the user can observe the depth of the drill rod into the tree through the measuring rod 110, and the user can also install a limiting rod on the measuring rod 110 to limit the position.

[0026] After the device completes the drilling, the user can leave the drill bit part in the tree hole, and also relax the pressing of the device, so that the drill bit part moves a distance out of the tree hole. Then the user can press the button 207, so that the button 207 drives the large gear plate 203 to move through the cross frame 206, so that the large gear plate 203 is engaged with the main shaft gear 202. Then the large gear plate 203 can drive the moving lead screw 204 to rotate. After the moving lead screw 204 rotates, it drives the compression cylinder 208 to move away from the torque gearbox 201. In this way, the compression cylinder 208 can squeeze the liquid medicine in the pressure chamber. When the cross frame 206 moves, the cross frame 206 also drives the inner slide shaft 303 to move through the slide column 209. After the inner slide shaft 303 moves, the liquid flow opening is opened. In this way, the liquid medicine squeezed by the compression cylinder 208 can be flushed into the tree through the liquid flow opening. The purpose of this is to make the liquid medicine quickly enter the tree hole. The liquid medicine is squeezed by the compression cylinder 208 to prevent the liquid medicine from not being able to be poured into the tree hole due to insufficient pressure. The liquid medicine poured into the deepest part of the tree hole will remain in the tree trunk, thereby avoiding the problem that the user's improper operation causes the medicine to not be poured into the deep part of the tree hole. After the liquid medicine enters the tree hole for a certain period of time, the motor is reversed, so that the compression cylinder 208 returns to the initial position while the drill rod part of the device is taken out of the tree trunk. When the drill rod is about to leave the tree hole, the button 207 is released, so that the large gear plate 203 and the conical drill bit 306 return to the initial position respectively. In this way, the device is ready for the next tree trunk for medicine application.

[0027] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application.
