The medicine application mechanism 8 is installed on the rear side of the housing 4.

[0030] As a preferred embodiment, the shearing mechanism 6 further includes: a mounting plate 61, a servo motor 62, a lead screw 63, a lead screw nut 64, a short connecting rod 65, a long connecting rod 66, a blade block 67, a shearing blade 68, and a push rod 69.

[0031] To enable automatic tree branch trimming, a mounting plate 61 is fixedly installed inside the housing 4. A servo motor 62 is fixedly installed at the bottom of the mounting plate 61. The output end of the servo motor 62 extends from the top of the mounting plate 61 and is locked with a lead screw 63. The servo motor 62 is existing technology. The servo motor 62 can drive the lead screw 63 to rotate clockwise or counterclockwise around its own axis. A lead screw nut 64 is screwed to the lead screw 63 and can move up and down under the drive of the lead screw 63. Sliding grooves are provided on both the left and right sides of the inner cavity of the housing 4, and sliders are inserted into the inner cavities of the sliding grooves. The slider is fixedly installed inside the lead screw nut 64 to limit the movement of the lead screw nut 64. The short connecting rod 65 is rotatably installed on one side of the inner cavity of the housing 4 through a pin. The long connecting rod 66 is rotatably installed on the other side of the inner cavity of the housing 4 through a pin. The blade block 67 is rotatably installed on one side of the short connecting rod 65 and the long connecting rod 66. The shearing blade 68 is fixedly installed inside the guide block 67, and the two shearing blades 68 are anchored together. The top left and right sides of the lead screw nut 64 are rotatably installed with push rods 69 through pins. One end of the push rod 69 is rotatably connected to one end of the long connecting rod 66.

[0032] In order to facilitate the starting of the servo motor 62, a battery 9 is provided in the inner cavity of the handle 3, and a control button 10 is provided at the bottom of the outer wall of the second support tube 2. The control button 10 is electrically connected to the battery 9 and the servo motor 62 to facilitate the starting of the servo motor 62.

[0033] As a preferred option, the long connecting rod 66 and the short connecting rod 65 are arranged in parallel to limit the movement of the blade block 67.

[0034] As a preferred option, one end of the long connecting rod 66 is inclined inward so that the push rod 69 can drive the long connecting rod 66 to swing.

[0035] As a preferred embodiment, the telescopic assembly 7 further includes: a plug 71, a socket 72, and a spring 73;

[0036] In order to fix and limit the first support tube 1 and the second support tube 2, the insert 71 is inserted into one side of the bottom of the outer wall of the first support tube 1. The outer wall of the second support tube 2 is provided with insertion holes 72 from top to bottom, and the insert 71 is inserted into the inner cavity of one of the insertion holes 72. The spring 73 is fixedly disposed between the insert 71 and the inner cavity of the first support tube 1.

[0037] As a preferred embodiment, the agent application mechanism 8 further includes: a cap 81, a cylinder 82, an insert 83, a push rod 84, a piston 85, a connecting pipe 86, a fixing plate 87, and a brush roller 88.

[0038] In order to deliver the medicine, the cap 81 is fixedly installed at the bottom of the outer wall of the handle 3, the cylinder 82 is screwed to the bottom of the cap 81, the insertion tube 83 is fixedly installed at the bottom of the handle 3 and located inside the cap 81, the insertion tube 83 is interference-fitted to the top of the cylinder 82, the push rod 84 is screwed to the bottom of the cylinder 82, the piston 85 is fitted into the inner cavity of the cylinder 82, and the top of the push rod 84 is rotatably connected to the bottom of the piston 85 through a bearing. Rotating the cylinder 82 can separate the cylinder 82 from the cap 81 so that the medicine can be filled into the cylinder 82.

[0039] To replenish the medication to the brush roller 88, a connecting tube 86 is fixedly installed at the bottom of the inner cavity of the handle 3. The connecting rod 86 is interference-fitted with the insertion tube 83. Fixing plates 87 are fixedly installed at both ends of the rear side of the housing 4. The brush roller 88 is rotatably mounted inside the fixing plate 87. The outer wall of the brush roller 88 extends out of one side of the fixing plate 87. One end of the connecting tube 86 passes through the second support tube 2 and the first support tube 1, extending out of the outer wall of the first support tube 1. The other end of the connecting tube 86 is fixedly installed on the upper side of the brush roller 88, which allows the medication in the cylinder 82 to be squeezed into the insertion tube 83, and then squeezed onto the brush roller 88 through the connecting tube 86.

[0040] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0041] Step 1: Press the insert 71 to compress the spring 73 and disengage it from the insertion hole 72, thereby releasing the fixed position of the first support tube 1 and the second support tube 2, so that the first support tube 1 can be extended or retracted within the second support tube 2 to complete the extension and retraction of the shearing blade 68.

[0042] Step 2: When cutting branches, start the servo motor 62 by controlling button 10, so that the servo motor 62 drives the lead screw 63 to rotate clockwise, so that the lead screw nut 64 moves upward, so that the long connecting rod 66 rotates through the moving push rod 69, thereby causing the blade 67 to move smoothly to both sides under the drive of the long connecting rod 66 and the short connecting rod 65, so that the cutting blades 68 on both sides are separated. By moving the lead screw nut 64 downward, the long connecting rod 66 is pulled to rotate through the push rod 69, so that the blade 67 drives the cutting blade 68 to automatically cut the branches.

[0043] Step 3: After cutting, move the housing 4 directly so that the brush roller 88 directly contacts the short branch section to apply the medicine to the cut. Rotate the push rod 84 to move the push rod 84 upward, thereby pushing the piston 85 upward, so that the medicine in the cylinder 82 can be squeezed into the insertion tube 83, and then squeezed onto the brush roller 88 through the connecting tube 86 to replenish the medicine. Thus, the pruning and medicine application work can be completed in one operation.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
