At the same time, it also extends the period of maintenance of the tool and improves the convenience of the device.

[0019] 3. The thickness of the docking groove at the bottom of the tool is greater than the thickness of the mounting strip, so that there is a gap between the bottom surface of the mounting strip and the branch cut surface during the tool cutting process, which is conducive to the uniform spraying of the agent to the branch cut surface through the spray hole, thereby improving the quality of the drug application work.

[0030] The existing electric scissors still have the following shortcomings during pruning: 1. After pruning the branches, the cross-section of branches with a diameter greater than 1.5 cm generally needs to be treated with medicine. The medicine treatment needs to be done manually through a spray device, which makes the work process cumbersome, increases the workload, and may result in omissions, increasing the risk of plant infection.

[0031] Second, the blade of the tool will gradually become blunt during use, which may result in uneven cuts and require more frequent maintenance, resulting in inconvenience in use.

[0032] When the present invention is used: Regarding question one; when it is necessary to apply medicine to the cut surface of the branch, the liquid supply component is started to guide the medicine into the cavity 49 of the strip plate 20 installed through the pipe joint 19 box. In the process of cutting the branch, the medicine in the cavity 49 is continuously sprayed onto the cut surface of the branch through the spray hole 50, thereby achieving the purpose of applying medicine while the cutting operation is performed; this setting achieves the purpose of instant medicine application, reduces the invasion of pathogens and pests, reduces the risk of plant infection, and makes full use of the pruning time. There is no need to spray medicine separately, which saves time and manpower and improves work efficiency. At the same time, it ensures that all incisions that need to be treated with medicine can be evenly covered with the medicine to avoid omissions, which helps to fully maintain the health of the plant.

[0033] Regarding the second question; during each cutting process, the tool 22 will contact the grinding component in the tool holder assembly. During the contact process, the grinding component grinds the tool 22. A tool holder is designed in the electric scissors so that the tool can grind the blade during each pruning process. This setting can ensure that the tool 22 always remains sharp, effectively improve the shearing efficiency, and can achieve clean incisions and improve the consistency of incisions, reduce the possibility of trees being infected, promote faster healing of wounds, and contribute to plant health. At the same time, it also extends the period of maintenance of the tool 22 and improves the ease of use of the device.

[0034] Specific: In the driving assembly, the DC reduction motor 28 drives the worm 41 to rotate, and the worm 41 drives the screw 25 to rotate through the worm wheel 26. The control mechanism controls the forward and reverse rotation and the start and stop of the DC reduction motor 28 to realize the cutting and trimming action of the tool assembly; In the tool assembly, the slide 24 moves along the axial direction of the guide rod 23 under the rotation drive of the screw 25, and the slide 24 drives the tool 22 to move through the mounting strip 20, thereby achieving the purpose of cutting the branches; wherein, the thickness of the docking groove 42 at the bottom of the tool 22 is greater than the thickness of the mounting strip 20, so that the tool 22 creates a gap between the bottom surface of the mounting strip 20 and the branch cut surface during the process of cutting the branches, which is beneficial for the agent to be evenly sprayed onto the branch cut surface through the spray hole 50, thereby improving the quality of the drug application work, and at the same time, this setting can alleviate the problem of blockage of the spray hole 50 during the cutting process, which is beneficial for ensuring the stability of the spraying treatment work.

[0035] In the knife seat assembly, when the knife 22 enters the knife groove 31, the blade surface of the knife 22 is pressed and contacted with the inclined surface 43 of the sharpening strip 33, thereby realizing the sharpening function of the knife 22; wherein the contact pressure between the inclined surface 43 and the knife 22 is provided by the spring 45, so the contact force between the inclined surface 43 and the knife 22 can be controlled by controlling the length of the spring 45; Wherein, the predetermined pressure of the pressure sensor 47 is assumed to be a, and the actual pressure is assumed to be b; when b is equal to a, the control mechanism controls the lifting motor 40 to be in a stopped state; when b is greater than a, the control mechanism controls the lifting motor 40 to rotate, so that the lifting plate 36 drives the hollow column 35 to rise, until b is equal to a; when b is less than a, the control mechanism controls the lifting motor 40 to rotate, so that the lifting plate 36 drives the hollow column 35 to descend, until b is equal to a; therefore, through the cooperation between the resistance component and the lifting component and the control mechanism, the inclined surface 43 can be kept in a state of consistent force to grind the blade surface of the tool 22, and the stable grinding force can reduce the wear of the tool 22, thereby extending the service life of the tool 22, and the stable grinding force helps to ensure the uniformity of the grinding of the tool 22, thereby improving the grinding quality; Among them, a is adjustable within a certain range and can be set according to the actual grinding effect, which has high flexibility and further improves the practicality of the present invention.

[0037] When the diameter of the branch to be cut reaches the point where it needs to be treated with medicine, the liquid pump 13 is started by button three 10. The liquid pump 13 guides the liquid medicine in the liquid medicine bottle 12 into the cavity 49 of the mounting strip 20 through the conduit 16 and the telescopic hose 14, and then sprays it out from the bottom surface of the mounting strip 20 through the spray hole 50. Among them, the arrangement of the liquid medicine bottle 12 and the threaded cover 17 allows the liquid medicine bottle 12 to be quickly disassembled, which is convenient for the replacement or replenishment of the medicine, thereby improving the ease of use of the present invention.

[0038] Embodiment 3: See also Figure 1 and Figure 2 On the basis of Example 2, the control mechanism includes a control box 6, in which a battery and a control module are arranged, and a charging port 7 for charging the box battery is arranged on the side of the control box 6; The top surface of the control box 6 is provided with button 1 8, button 2 9 and button 3 10 which are electrically connected to the control module. Button 1 8 is used to control the rotation direction of the DC reduction motor 28, button 2 9 is used to control the start and stop of the DC reduction motor 28, and button 3 10 is used to control the start and stop of the liquid supply component.

[0039] The control module can use PLC (Programmable Logic Controller); In the drive assembly, button 1 8 and button 2 9 cooperate with PLC to control the direction and start and stop of the DC reduction motor 28; PLC cooperates with keys to control the start, stop and direction of the motor. This control method is widely used in industrial automation, mechanical equipment, production lines and other fields, which can improve the flexibility and safety of operation and is a prior art.

[0040] In the polishing assembly, the forward and reverse rotation and start and stop of the lifting motor 40 are controlled by feedback from the pressure sensor 47; PLC cooperates with the pressure sensor to control the start and stop and forward and reverse rotation of the motor, which is a common control scheme in the field of industrial automation and is a prior art.

[0041] In the liquid supply component, the liquid pump 13 is turned on and off by button three 10; PLC controls the turning on and off of the liquid pump by buttons, which is a technology widely used in industrial automation and liquid delivery systems and is a prior art.

[0042] Embodiment 4: See also Figure 1 and Figure 2 On the basis of Example 2, the connecting rod assembly includes a hollow rod 1, and an extension rod 4 is slidably inserted at the front end of the hollow rod 1.

[0043] The hollow rod 1 and the extension rod 4 in the connecting rod assembly form a hand-held rod with adjustable working length, so that the user can adjust the length according to the pruning position within a certain range, thereby improving the practicality of the present invention.

[0044] Embodiment 5: See also Figure 4On the basis of Example 1, a grinding sheet 32 ​​is fixedly installed on the inner bottom surface of the knife groove 31. Through the setting of the grinding sheet 32, the bottom surface of the tool 22 can also be polished when the tool 22 enters and exits the knife groove 31, thereby improving the flatness of the branch incision; the thickness of the grinding sheet 32 ​​should be sufficient to ensure that there is sliding contact between the grinding sheet 32 ​​and the bottom surface of the tool 22, thereby ensuring a grinding effect, and the specific thickness can be adjusted according to actual grinding requirements and effects.

[0045] Embodiment 6: On the basis of Example 1, a rubber layer is provided on the inner side surface of the knife holder 30.
