[0002] In the field of landscaping construction, tree pruning is a crucial and frequently performed task. Traditional landscaping tree pruning equipment presents several problems in practical use, directly impacting the efficiency, quality, and operator experience. Firstly, it is significantly lacking in ease of operation. Previous pruning equipment typically required users to grip a hollow control lever tightly with both hands, leading to hand muscle fatigue and high labor intensity over extended periods, thus affecting work efficiency and sustained work capacity. This traditional grip lacks flexibility and cannot adapt to different user habits or diverse pruning scenarios. Secondly, the equipment's stability and safety also have room for improvement. Existing lever fixing methods and auxiliary device designs are inadequate, making the equipment prone to shaking or displacement during operation, affecting pruning accuracy. Utility Model Content

[0003] The main purpose of this utility model is to propose a garden construction seedling pruning device, which aims to solve the problem that the previous pruning equipment usually requires the user to hold the hollow operating rod with both hands to operate, which will lead to hand muscle fatigue, high labor intensity, and affect work efficiency and continuous working ability after a long period of operation.

[0004] To address the aforementioned problems, this utility model proposes a garden construction seedling pruning device, comprising a pruning motor and a widened fixing ring sleeved and fixed to the lower outer side of the center of the pruning motor. The widened fixing ring is fixedly connected to the outer shell of the pruning motor by welding. A metal fixing sleeve is welded to the rear end of the widened fixing ring, and a hollow operating rod is inserted and fixed in the metal fixing sleeve. The hollow operating rod extends horizontally to the rear and is fixedly connected to the metal fixing sleeve by screws. The hollow through hole inside the hollow operating rod is used for electrical wiring. The hollow operating rod is made entirely of aluminum alloy, and a variable auxiliary operating device is sleeved on the rear outer side of the center of the hollow operating rod.

[0005] In one embodiment, the variable auxiliary operation device includes a resistance pad, a vertical operating lever, an anti-slip sleeve, an extended U-shaped disassembly sleeve, and a U-shaped effort-saving grip. The resistance pad is glued to the inner wall of the extended U-shaped disassembly sleeve, and the extended U-shaped disassembly sleeve and the resistance pad on the inner wall are sleeved on the outer side of the center of the hollow operating lever. The opening of the extended U-shaped disassembly sleeve faces downward. A vertical operating lever is welded to the outer wall of the rear top of the center of the extended U-shaped disassembly sleeve. An anti-slip sleeve is sleeved on the outside of the vertical operating lever. U-shaped effort-saving grips are provided on the outer walls of the front top of the center of the extended U-shaped disassembly sleeve and on both the left and right ends.

[0006] In one embodiment, the vertical operating lever is set in an upward vertical extension state at the top of the extended U-shaped disassembly sleeve, the vertical operating lever is close to the rear end of the extended U-shaped disassembly sleeve, the top of the anti-slip sleeve is set as a hemisphere, the U-shaped labor-saving grip is set longitudinally on the outer wall of the extended U-shaped disassembly sleeve, and the two corners of the U-shaped labor-saving grip are both treated with arc surface blunting.

[0007] In one embodiment, the variable auxiliary operation device further includes a U-shaped reinforcing ring, a fixing screw, a clamping nut, and a screw through hole. Three U-shaped reinforcing rings are provided, and the three U-shaped reinforcing rings are respectively sleeved and fixed on the front and rear ends and the outer wall of the center of the extended U-shaped disassembly sleeve. Screw through holes are provided inside the left and right ends of the openings of the three U-shaped reinforcing rings, and the screw through holes simultaneously penetrate the extended U-shaped disassembly sleeve. Fixing screws are inserted into the screw through holes inside the openings of the three U-shaped reinforcing rings, and clamping nuts are threaded onto the outer sides of the left and right ends of the three fixing screws.

[0008] In one embodiment, the clamping nuts on the left and right sides of the fixing screw are located on the left and right sides of the extended U-shaped disassembly sleeve, respectively. The clamping nuts can rotate clockwise and counterclockwise to move left and right on the outside of the fixing screw through the action of the threads. When the clamping nuts on both sides of the fixing screw move towards the center of the fixing screw, the two clamping nuts will retract the bottom opening of the extended U-shaped disassembly sleeve towards the center of the fixing screw.

[0009] In one embodiment, the inner resistance pad is made of soft rubber, and the inner wall of the U-shaped inner resistance pad is densely covered with outwardly protruding anti-slip particles. During the inward contraction of the bottom opening of the extended U-shaped disassembly sleeve, the inner resistance pad will be clamped onto the outer wall of the hollow operating rod. After the inner resistance pad is completely attached to and clamped onto the outer wall of the hollow operating rod, it can prevent the extended U-shaped disassembly sleeve from moving forward and backward or rotating clockwise and counterclockwise on the outside of the hollow operating rod.

[0010] In one embodiment, the trimming motor has a motor rotor inside, and a motor output shaft is provided at the center of the motor rotor. The motor output shaft is vertically downward and a fixed bushing is sleeved on the bottom end of the motor output shaft. The fixed bushing and the motor output shaft are fixedly connected by multiple internal hole fixing screws.

[0011] In one embodiment, a plurality of strip-shaped pruning shears are equidistantly fixed on the circular outer wall of the bottom end of the fixed bushing, and the pruning motor can drive the plurality of strip-shaped pruning shears outside the fixed bushing to rotate through the motor output shaft.

[0012] In one embodiment, a fixing flange is welded to the outer wall of the bottom end of the widened fixing ring, and a protective plate is provided at the bottom end of the fixing flange. The fixing flange is fixedly connected to the protective plate by multiple screws, and the protective plate protects above multiple strip-shaped pruning shears.

[0013] In one embodiment, a battery mounting plate is provided at the rear end of the hollow operating lever. A storage battery is fixed to the rear end of the battery mounting plate by a plurality of hand-tightened screws. The storage battery is electrically connected to the trimming motor through wires, and the wires are inserted into the hollow through holes inside the hollow operating lever.

[0014] Beneficial Effects: The technical solution of this utility model adds a novel variable auxiliary operating device to the outside of the hollow operating rod of the garden pruning equipment. This variable auxiliary operating device changes the way the user operates the equipment, making it more convenient and labor-saving. Furthermore, the variable auxiliary operating device can flexibly change its position and angle on the outside of the hollow operating rod according to the user's needs. In terms of ease of operation and labor saving, the variable auxiliary operating device completely changes the traditional gripping method. Previously, users had to grip the hollow operating rod tightly with both hands; now, they only need to hold the anti-slip sleeve on the outside of the vertical operating rod with their left hand and the U-shaped labor-saving handle with their right hand. This new method greatly reduces hand burden, making operation easier and less strenuous, effectively reducing the user's labor intensity. Secondly, in terms of flexibility and adaptability, the device can flexibly change its position and angle on the outside of the hollow operating rod according to the user's needs, adapting to different user habits and various actual pruning scenarios. Furthermore, in terms of stability, the inner resistance pad and U-shaped reinforcing ring work together to prevent displacement or rotation of the device, ensuring stable operation.

[0028] This utility model provides, for example Figure 1-6The illustrated garden pruning equipment includes a pruning motor 7 and a widened fixing ring 6 fixed to the lower outer side of the center of the pruning motor 7. The widened fixing ring 6 is fixedly connected to the outer shell of the pruning motor 7 by welding. A metal fixing sleeve 5 is welded to the rear end of the widened fixing ring 6, and a hollow operating rod 3 is inserted and fixed in the metal fixing sleeve 5. The hollow operating rod 3 extends horizontally backward and is fixedly connected to the metal fixing sleeve 5 by screws. The hollow through hole inside the hollow operating rod 3 is used for electrical wiring. The hollow operating rod 3 is made entirely of aluminum alloy. The widened fixing ring 6 not only provides stable support for the motor but also serves as a connection base for other components. The metal fixing sleeve 5 welded to the rear end of the widened fixing ring 6 is used to insert and fix the hollow operating rod 3. The hollow operating rod 3 extends horizontally backward and is fixedly connected to the metal fixing sleeve 5 by screws. This connection method ensures that the hollow operating rod 3... The hollow operating lever 3 is made entirely of aluminum alloy, ensuring both stability and ease of disassembly and maintenance. This reduces the overall weight of the equipment while maintaining structural strength, making it easier for users to operate. Furthermore, the hollow through-hole design inside the operating lever 3 facilitates wiring, resulting in a neater and safer wiring layout and avoiding potential safety hazards from exposed wires. A battery mounting plate 2 is located at the rear of the hollow operating lever 3, with a storage battery 1 secured to it by multiple hand-tightened screws. This securing method facilitates battery installation and removal, allowing for timely replacement or charging when the battery is low. The storage battery 1 is electrically connected to the pruning motor 7 via wires that pass through the hollow through-holes inside the operating lever 3. This wiring method ensures the stability and safety of power transmission, providing continuous power support to the pruning motor 7 and guaranteeing the normal operation of the entire seedling pruning equipment.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the trimming motor 7 contains a motor rotor, with a motor output shaft 13 positioned at the center of the rotor. The motor output shaft 13 is vertically downward. The trimming power originates from the trimming motor 7. The motor rotor inside the motor is the core component for power generation. When the motor is powered on and started, the motor rotor begins to rotate at high speed, thereby driving the motor output shaft 13 at the center to rotate synchronously. The vertical downward orientation of the motor output shaft 13 facilitates the vertical downward transmission of power, ensuring the stability and efficiency of power transmission. A fixed bushing 12 is sleeved on the bottom of the motor output shaft 13. The fixed bushing 12 and the motor output shaft 13 are fixedly connected by multiple internal fixing screws 11. This connection method ensures the power of the motor output shaft 13. The power can be reliably transmitted to the fixed bushing 12. Multiple strip-shaped pruning shears 8 are equidistantly fixed on the circular outer wall of the bottom end of the fixed bushing 12. The pruning motor 7 can drive the multiple strip-shaped pruning shears 8 outside the fixed bushing 12 to rotate through the motor output shaft 13. The high-speed rotating strip-shaped pruning shears 8 form a powerful cutting ability, which can quickly and accurately prune the excess parts of the seedlings. The bottom outer wall of the widened fixed ring 6 is welded with a fixed flange 9. The bottom end of the fixed flange 9 is provided with a protective plate 10. The fixed flange 9 is fixedly connected to the protective plate 10 by multiple screws. The protective plate 10 protects the multiple strip-shaped pruning shears 8. The protective plate 10 can effectively block the splashing of seedling debris and debris during the pruning process and protect the safety of the operator.

[0030] like Figure 1 , Figure 5 and Figure 6As shown, a variable auxiliary operating device 4 is sleeved on the outer rear side of the center of the hollow operating lever 3. The variable auxiliary operating device 4 includes a resistance pad 14, a vertical operating lever 15, an anti-slip sleeve 16, an extended U-shaped disassembly sleeve 17, and a U-shaped effort-saving grip 19. The resistance pad 14 is glued and fixed to the inner wall of the U-shaped disassembly sleeve 17, and the extended U-shaped disassembly sleeve 17 and the resistance pad 14 on the inner wall are sleeved on the outer rear side of the center of the hollow operating lever 3. The opening of the extended U-shaped disassembly sleeve 17 faces downward, and the extended U-shaped disassembly sleeve 17 provides a basic foundation for the entire variable auxiliary operating device 4. The extended U-shaped mounting sleeve 17, with its opening facing downwards, is fitted onto the outer rear side of the center of the hollow operating rod 3. This design not only facilitates installation and disassembly operations on the hollow operating rod 3 but also ensures the stability of the device during use. A vertical operating rod 15 is welded to the outer wall of the rear top of the center of the extended U-shaped mounting sleeve 17. An anti-slip sleeve 16 is fitted onto the outside of the vertical operating rod 15. U-shaped effort-saving grips 19 are provided on the outer walls of the front top of the center of the extended U-shaped mounting sleeve 17 and on both sides. The vertical operating rod 15 is angled downwards at the top of the extended U-shaped mounting sleeve 17. In the vertically extended position, the vertical operating lever 15 is positioned near the rear end of the extended U-shaped disassembly sleeve 17. The anti-slip sleeve 16 has a hemispherical top, a design that conforms to ergonomic principles, making it easy for the user to grip. Furthermore, the material and shape of the anti-slip sleeve 16 effectively increase the friction between the hand and the vertical operating lever 15, preventing hand slippage during operation and improving safety and comfort. The U-shaped effort-saving grip 19 is longitudinally positioned on the outer wall of the extended U-shaped disassembly sleeve 17. Both corners of the U-shaped effort-saving grip 19 are rounded and blunted. The effort-saving grip 19 conforms to the human hand's gripping habits. During operation, users can flexibly choose to hold the U-shaped effort-saving grip 19 in different positions according to their own needs and habits. The rounded and blunt treatment avoids sharp edges from causing injury to the hands, while also improving grip comfort. Through this unique design, when operating the trimming equipment, users only need to hold the anti-slip sleeve 16 on the outside of the vertical operating lever 15 with their left hand and hold the U-shaped effort-saving grip 19 with their right hand to easily change the traditional gripping method, greatly reducing the burden on the hands and achieving a more effortless operation.

[0031] like Figure 1 , Figure 5 and Figure 6As shown, the variable auxiliary operating device 4 also includes a U-shaped reinforcing ring 18, a fixing screw 20, a clamping nut 21, and a screw through hole 22. Three U-shaped reinforcing rings 18 are provided, each sleeved and fixed to the front and rear ends and the center of the extended U-shaped disassembly sleeve 17. Screw through holes 22 are provided inside the left and right ends of the openings of the three U-shaped reinforcing rings 18, and these holes simultaneously penetrate the extended U-shaped disassembly sleeve 17. Fixing screws 20 are inserted into the screw through holes 22 inside the openings of the three U-shaped reinforcing rings 18. Both ends of the screw 20 are threaded with clamping nuts 21. These clamping nuts 21 are located on the outer sides of the extended U-shaped disassembly sleeve 17. The clamping nuts 21 can rotate clockwise or counterclockwise, allowing them to move left and right on the outside of the screw 20 through the threaded action. When the clamping nuts 21 move towards the center of the screw 20, they retract towards the center of the extended U-shaped disassembly sleeve 17, opening at the bottom. The U-shaped reinforcing ring 18... There are three in total, which are respectively fitted and fixed to the front and rear ends and the outer wall of the U-shape at the center of the extended U-shaped assembly sleeve 17. This layout can reinforce the extended U-shaped assembly sleeve 17 from all directions. Each U-shaped reinforcing ring 18 has screw holes 22 inside at both ends of its opening, and these screw holes 22 simultaneously penetrate the extended U-shaped assembly sleeve 17. Fixing screws 20 are inserted into the screw holes 22, and clamping nuts 21 are threaded onto the outside of both ends of the fixing screws 20. When it is necessary to adjust the position of the variable auxiliary operating device 4 on the hollow operating rod 3, The user can achieve this by rotating the clamping and fixing nuts 21. The clockwise and counterclockwise rotation of the clamping and fixing nuts 21 can cause them to move left and right outside the fixing screw 20 through the action of the threads. When both clamping and fixing nuts 21 move towards the center of the fixing screw 20, they will shrink the bottom opening of the extended U-shaped disassembly and assembly sleeve 17, further enhancing the friction between the inner resistance pad 14 and the hollow operating rod 3, thereby more firmly fixing the variable auxiliary operating device 4. Conversely, if it is necessary to disassemble or readjust the position, the clamping and fixing nuts 21 can be rotated in the opposite direction.

[0032] like Figure 1 , Figure 5 and Figure 6As shown, a resistance pad 14 is adhered and fixed to the inner wall of the U-shaped extension sleeve 17. The resistance pad 14 is made of soft rubber, and its U-shaped inner wall is densely covered with outwardly protruding anti-slip particles. This special material and surface design make the resistance pad 14 play a key role in the installation and use of the device. When the bottom opening of the extension U-shaped extension sleeve 17 contracts inward, the resistance pad 14 will clamp onto the outer wall of the hollow operating rod 3. After the resistance pad 14 is fully attached and clamped onto the outer wall of the hollow operating rod 3, it can prevent the extension U-shaped extension sleeve 17 from moving forward and backward or rotating clockwise and counterclockwise outside the hollow operating rod 3. The resistance pad 14 is fully attached. After being clamped to the outer wall of the hollow operating rod 3, it can generate sufficient friction to effectively prevent the extended U-shaped disassembly sleeve 17 from shifting forward and backward or rotating clockwise and counterclockwise on the outside of the hollow operating rod 3. This ensures the stability of the position of the variable auxiliary operating device 4 on the hollow operating rod 3, thereby guaranteeing the accuracy and reliability of the user's operation. Through the ingenious cooperation between the various components, the variable auxiliary operating device 4 achieves flexible installation and fixation on the hollow operating rod 3, flexible adjustment of position and angle, and provides users with a more comfortable and labor-saving operating experience, effectively improving the overall performance and user experience of the garden construction seedling pruning equipment.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
