[0033] Referring to Figure 3The cleaning assembly comprises two fixed plates 10 fixedly connected to the middle side of the front part of the mounting box 3, which provides a stable support structure for the entire cleaning assembly. The fixed plates 10 are internally slidably connected to a limiting plate 11, which can move flexibly in the fixed plates 10, thereby driving the connecting rod 13 and the scraper 14 to perform corresponding cleaning actions, which can adapt to the cleaning needs of different positions and quantities of sundries. The limiting plate 11 is fixedly connected to a first spring 12 on one side. When the limiting plate 11 is moved by an external force, the first spring 12 is compressed or stretched, storing elastic potential energy. When the external force disappears, the first spring 12 uses its elastic restoring force to pull the limiting plate 11 back to its original position, so that the cleaning assembly can maintain the initial state when not in use. At the same time, it can also buffer the impact force between the limiting plate 11 and the fixed plate 10 during the cleaning process, protecting the various components of the cleaning assembly. The limiting plate 11 is fixedly connected to a connecting rod 13 on the other side. The connecting rod 13 serves as an intermediate component connecting the limiting plate 11 and the scraper 14, and transmits the movement of the limiting plate 11 to the scraper 14, so that the scraper 14 can perform effective cleaning actions with the movement of the limiting plate 11.

[0034] Referring to Figure 4 The adjusting assembly comprises a pressing rod 15 and a plurality of clamping blocks 16. The pressing rod 15 is slidably connected inside one of the mounting plates 7. The pressing rod 15 serves as an operating component of the adjusting assembly, which is slidably connected inside one of the mounting plates 7. This design allows users to conveniently adjust the opening and closing degree of the cutter 8 by pressing the pressing rod 15, meeting the pruning needs of green plant branches of different thicknesses. The clamping blocks 16 are fixedly connected to the outer wall of the rack plate 9. The clamping blocks 16 are used in cooperation with inclined blocks 19 on the pressing rod 15 to fix and adjust the position of the rack plate 9, thereby controlling the opening and closing degree of the cutter 8. The outer wall of the pressing rod 15 is fixedly connected to a limiting block 17, which limits the sliding range of the pressing rod 15 to prevent it from coming off the mounting plate 7 during sliding. The bottom of the limiting block 17 is fixedly connected to a second spring 18, which functions similarly to the first spring 12, serving as a reset and buffer. When the pressing rod 15 is pressed down, the second spring 18 is compressed, storing elastic potential energy. When the user releases the pressing rod 15, the second spring 18 uses its elastic restoring force to push the pressing rod 15 back to its original position, allowing the adjusting assembly to return to the initial state. The bottom of the limiting block 17 is fixedly connected to an inclined block 19, which cooperates with the clamping blocks 16. Through the design of the inclined surface, the pressing rod 15 can conveniently realize the clamping and separation between the clamping blocks 16 and the inclined blocks 19 during pressing and releasing, thereby quickly and accurately adjusting the opening and closing degree of the cutter 8.

[0035] With reference to Figure 1 And Figure 2 , the handle 1 is provided with a button 2, which is electrically connected between the button 2 and the motor 4. The button 2 serves as a component for controlling the power on / off and starting and stopping of the entire trimming device. The position of the button 2 is arranged on the handle 1, so that the user can easily press the button 2 with fingers to control the operation of the device when holding the handle 1 to trim. The electric connection enables the button 2 to directly control the starting and stopping of the motor 4, thereby indirectly controlling the rotary motion of the half gear 5.

[0036] With reference to Figure 2 The half gear 5 is engaged with the rack plate 9. When the motor 4 drives the half gear 5 to rotate, the rotary motion of the half gear 5 can be converted into the linear reciprocating motion of the rack plate 9 due to the engagement relationship between the half gear 5 and the rack plate 9, thereby driving the mounting plate 7 and the cutter 8 to open and close.

[0037] With reference to Figure 2 One end of the third spring 20 is fixedly connected inside the mounting box 3, and the other end of the third spring 20 is fixedly connected to the outer wall of one of the mounting plates 7. The third spring 20 also plays a role of resetting and buffering. During the opening and closing of the cutter 8, when the mounting plate 7 is moved under the action of external force, the third spring 20 is compressed or stretched, storing elastic potential energy. When the external force disappears, the third spring 20 uses its own elastic restoring force to pull the mounting plate 7 back to the original position, so that the cutter 8 can return to the initial state.

[0038] With reference to Figure 1 And Figure 4 The clamping block 16 penetrates the mounting plate 7 and is clamped between the inclined block 19. The clamping manner enables the position of the mounting plate 7 to be fixed, thereby realizing precise control of the opening and closing degree of the cutter 8. The surface of the mounting box 3 is provided with a sliding groove 21, and the outer wall of the pressing rod 15 is slidingly connected inside the sliding groove 21. The sliding groove 21 provides a guide and limiting action for the sliding operation of the pressing rod 15, so that the pressing rod 15 can stably slide in the sliding groove 21, ensuring the normal operation of the adjusting assembly during trimming.

[0039] With reference to Figure 4 The outer wall of the limiting block 17 is slidingly connected inside the mounting plate 7. The sliding connection enables the limiting block 17 to stably move inside the mounting plate 7, thereby driving the pressing rod 15 to perform corresponding adjustment operation. The second spring 18 is fixedly connected to the inner wall of the mounting plate 7 away from the limiting block 17, so that the second spring 18 can stably exert its resetting and buffering action on the mounting plate 7, thereby providing protection for the normal operation of the adjusting assembly.

[0040] Working principle: when the user holds the handle 1 and presses the button 2, the button 2 connects the power supply of the motor 4, the motor 4 starts to run, its output end drives the half gear 5 to rotate. Because the half gear 5 and the rack plate 9 at the rear of the mounting plate 7 are engaged with each other, the rotary motion of the half gear 5 is converted into the linear reciprocating motion of the rack plate 9.

[0041] Under the guidance of the slide rod 6, the mounting plate 7 stably slides along the slide rod 6, and the cutter 8 connected with the mounting plate 7 also moves to open and close. When the toothed part of the half gear 5 is engaged with the rack plate 9, the rack plate 9 drives the mounting plate 7 and the cutter 8 to move inward, realizing the closing of the cutter 8, so as to cut the branches of the green plants; when the toothless part of the half gear 5 rotates to contact the rack plate 9, under the elastic restoring force of the third spring 20, the mounting plate 7 and the cutter 8 move outward, the cutter 8 is opened, and is ready for the next cutting action.

[0042] During the trimming process, if it is necessary to adjust the opening and closing degree of the cutter 8 to adapt to different thicknesses of the branches, the user can operate the adjusting assembly on the inner wall of one of the mounting plates 7. By pressing the pressing rod 15, the limiting block 17 on the pressing rod 15 compresses the second spring 18 and moves downward, and the inclined block 19 at the bottom thereof changes the clamping state with the clamping block 16, at this time, the user can push or pull the mounting plate 7 to adjust the position thereof, and further change the opening and closing degree of the cutter 8. After the pressing rod 15 is released, the second spring 18 returns to the original state, the inclined block 19 is clamped with the clamping block 16 again, the mounting plate 7 is fixed at the new position, and the cutter 8 is kept in the adjusted opening and closing state.

[0043] Meanwhile, during the trimming process, the cleaning assembly at the front of the mounting box 3 also plays a role. When there are branch debris and other sundries attached to the surface of the cutter 8, along with the movement and operation of the trimming device, the limiting plate 11 will slide in the fixed plate 10, and the first spring 12 on one side thereof will be compressed or stretched. The connecting rod 13 connected with the other side of the limiting plate 11 drives the scraper 14 to scrape and clean the sundries on the cutter 8, keeps the working area of the trimming device clean, and prevents the sundries from affecting the normal work of the cutter 8 and the subsequent trimming operation.

[0044] Finally, it should be pointed out that the above description is only the preferred embodiment of the present application and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
