Description
Technical Field
[0001] This utility model relates to the field of garden tool technology, and more specifically to a pruning kit that combines handheld operation and high-branch operation functions. Background Technology
[0002] High-altitude tree pruning is widely used in various fields such as forest pruning, garden maintenance, municipal management, and power line maintenance. Existing technologies offer a variety of high-altitude tree pruning tools, but they have shortcomings in terms of portability and operational flexibility, specifically: 1. Limited tool functionality hinders rapid adaptation to diverse work scenarios. Existing market products typically come in a single form: either a handheld chainsaw suitable for ground work but inaccessible to heights, or a fixed-length peg saw that, while extendable, is bulky and cannot be disassembled for a lightweight handheld mode. Workers must carry multiple tools to handle branches of varying heights, resulting in cumbersome tool management and preventing the efficient use of "one set of tools for two purposes."
[0003] 2. The user experience in high-pole operation mode is poor, requiring significant effort and exhibiting instability. Most existing high-pole chainsaws employ a fixed or simply extendable design, with the drive battery typically fixed to the saw head or the top of the shaft. This layout results in a severely high and forward center of gravity for the entire tool. The operator must continuously apply enormous torque to counteract gravity and stabilize the saw head, leading to strenuous operation, severe shaft swaying, and difficulty in controlling cutting accuracy. This not only greatly increases labor intensity but also introduces safety hazards due to operational instability.
[0004] Therefore, how to provide a highly integrated pruning kit that can quickly switch between two working modes—portable handheld and stable high-branch—is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the present invention provides a pruning kit that combines handheld operation and high-branch operation functions, aiming to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A pruning kit that combines handheld and high-branch operation functions includes an equipment case, and a saw head assembly, a shaft assembly, and a power supply unit integrated inside the equipment case. The rod assembly includes at least two detachably connected rod segments; The power supply unit includes a first battery and a second battery with different capacities. The first battery is used to be installed on the saw head assembly to provide power for handheld operation; or, multiple pole segments are connected together and detachably connected to the saw head assembly, and the second battery is used to be installed on any of the pole segments and connected to the power supply interface of the saw head assembly via a wire to provide power for high-branch operation.
[0007] Through the above technical solution, this utility model discloses a pruning kit that combines handheld and high-branch operation functions. The core components are integrated and portable through the equipment box, effectively solving the problem of scattered tool components and inconvenient management. Through the design of at least two detachable rod sections and dual batteries of different capacities, the technical basis for one tool to flexibly switch between two operation modes is realized. When the first battery is used for direct power supply, it constitutes a lightweight handheld chainsaw; when the second battery is used for power supply through the rod, it constitutes an extendable high-branch chainsaw. This realizes one tool with two uses, greatly improving the adaptability and efficiency of operation.
[0008] Preferably, in the aforementioned pruning kit that combines handheld and high-branch operation functions, the saw head assembly has an interface holder that can be detachably connected to either the first battery or the top of the pole assembly. A standardized mechanical and electrical interface is provided on the saw head assembly; this interface holder is a key hub for achieving rapid and reliable mode switching, making the installation / removal of the first battery and the connection / disconnection of the entire pole assembly simple, intuitive, and robust, thus improving the kit's usability and reliability.
[0009] Preferably, in the aforementioned pruning kit that combines handheld and high-branch operation functions, the pole assembly includes a top section pole, a middle section pole, and a bottom section pole that are detachably connected in sequence. The top section pole has a mounting base detachably connected to the interface bracket at its top end, and a battery bracket for mounting the second battery is fixed at its bottom end. The power cord is located inside the top section pole, and its two ends are respectively connected to the power supply interface of the battery bracket and the power supply interface of the saw head assembly. This specifies the optimal configuration of the pole assembly (top, middle, and bottom sections). Its core lies in the integrated design of the top section pole: the top end connects to the saw head, the bottom end integrates the second battery mounting base, and the internal power cord is located. This design moves the battery in high-branch operation mode from the traditional saw head position to the pole body, lowering the center of gravity of the entire tool system, making operation more effortless and stable during high-branch operations, thereby improving the operating experience; at the same time, the integrated power supply line avoids the risk of tangling and damage caused by exposed wires.
[0010] Preferably, the pruning kit described above, which combines handheld and high-branch operation functions, further includes a rotating mechanism for driving the saw head assembly. The rotating mechanism includes a connecting plate fixed to the top of the top section of the pole and a drive motor mounted on the connecting plate. The power output shaft of the drive motor passes through the connecting plate and is fixed to the mounting base. This adds an electric angle adjustment function to the saw head. By remotely controlling the drive motor, the saw head can be driven to rotate in the horizontal plane, thereby achieving precise and remote adjustment of the sawing angle. This allows the operator to efficiently complete horizontal, oblique, and other multi-angle cutting tasks without frequently moving or adjusting the pole's posture, significantly improving operational flexibility, accuracy, and safety, especially in complex canopy environments.
[0011] Preferably, in the aforementioned pruning kit that combines handheld and high-branch operation functions, the base pole is a fiberglass pole. The outer wall of the base pole has an insulating skirt and a silicone grip, and its interior is filled with polyurethane foam. This provides double insulation protection: firstly, fiberglass is used as the pole's base material; secondly, the pole is filled with closed-cell polyurethane foam, which not only enhances the pole's bending strength but also further blocks any potential electrical pathways within it. The outer insulating skirt increases the creepage distance; this structure together forms a multi-layered insulation barrier from the inside out, greatly improving safety when working in high-humidity environments or near live power lines.
[0012] Preferably, in the aforementioned pruning kit that combines handheld and high-branch operation functions, a U-shaped retaining ring is detachably connected to the base section of the pruning rod, and a remote control switch is installed on the U-shaped retaining ring. Through the U-shaped retaining ring, the remote control switch can be quickly installed at any suitable position on the base section of the pruning rod (near the operator's grip area), facilitating thumb operation. Its detachable connection also allows for easy adjustment or removal according to personal habits, optimizing the human-machine interaction experience.
[0013] Preferably, in the aforementioned pruning kit that combines handheld and high-branch operation functions, the equipment box integrates a power module, a battery charging dock, and a storage area for the remote control switch. The energy supply system is deeply integrated into the equipment box; the integrated power module (portable power supply) allows for on-site battery charging; the integrated battery charging dock provides a convenient charging interface; and the remote control switch storage area enables organized management of accessories. This design upgrades a simple packaging box into a mobile charging station and workstation, solving battery anxiety and equipment management problems during outdoor operations.
[0014] Preferably, in the above-mentioned pruning kit that combines handheld and high-branch operation functions, there are two battery charging stations, one for the first battery and the other for the second battery. Providing independent dedicated charging stations for the first battery (handheld mode) and the second battery (high-branch mode) allows both batteries to be charged simultaneously, minimizing battery replenishment cycles and ensuring the needs of high-intensity, continuous operation.
[0015] Preferably, in the aforementioned pruning kit that combines handheld and high-branch operation functions, the equipment box has two battery storage slots for the first battery and the second battery, respectively. The equipment box provides dedicated storage locations for two batteries of different capacities and uses; this ensures that the batteries will not collide or wear during transportation and storage, and can be quickly located and retrieved, reflecting the kit's refined and user-friendly design.
[0016] Preferably, in the aforementioned pruning kit that combines handheld and high-branch operation functions, the equipment box integrates a lubricating oil filling funnel. This allows the operator to easily lubricate and maintain the saw head assembly at any time, extending tool life, maintaining optimal cutting performance, and preventing situations where forgetting to bring maintenance tools affects the operation, thus improving the completeness and convenience of the kit.
[0017] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a pruning kit that combines handheld operation and high-branch operation functions, and has the following beneficial effects: 1. This utility model provides a highly integrated pruning kit, effectively solving the problems of fragmented and disjointed functions in traditional aerial pruning tool systems. The saw head, detachable shaft, dual-mode power supply unit, and all accessories are integrated into a single equipment box, realizing the transformation from multiple scattered tools to a single integrated system. This design allows operators to quickly and flexibly switch between two modes—a portable handheld chainsaw and a stable, extended high-pole chainsaw—according to site requirements, greatly improving operational adaptability and deployment efficiency.
[0018] 2. This utility model optimizes the tool's center of gravity distribution by moving the power supply battery to the lower part of the pole in high-pole mode. This effectively lowers the tool's center of gravity in high-pole mode, making operation more effortless and stable during high-altitude work. The rotating mechanism integrated into the saw head supports remote and precise adjustment of the cutting angle, enhancing operational flexibility and accuracy. Simultaneously, the pole body, employing a multi-layer composite insulation structure (such as fiberglass substrate, internal foam filling, and external umbrella skirts), provides safety far exceeding that of traditional single-layer insulated pole bodies for operation in complex or electrified environments.
[0019] 3. This utility model deeply integrates a mobile power supply and an intelligent charging management module into the equipment storage box, constructing a self-sustaining energy replenishment system and effectively solving the bottleneck of field endurance. In addition, the carefully designed dedicated battery slot, remote control placement area, and integrated maintenance tools (such as a lubricating oil funnel) ensure the convenience of equipment management and the timeliness of maintenance, thus forming a complete, reliable, and efficient modern pruning tool.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] See appendix Figure 1 As shown, this utility model embodiment discloses a pruning kit that combines handheld operation and high-branch operation functions, including an equipment box 1, and a saw head assembly 2, a pole assembly 3 and a power supply unit 4 integrated inside the equipment box 1. The rod assembly 3 includes at least two detachably connected rod segments; The power supply unit 4 includes a first battery 41 and a second battery 42 with different capacities. The first battery 41 is used to be installed on the saw head assembly 2 to provide power for handheld operation; or, multiple pole segments are connected together and detachably connected to the saw head assembly 2. The second battery 42 is used to be installed on any pole segment and connected to the power supply interface of the saw head assembly 2 via a wire to provide power for high-branch operation.
[0025] In some specific examples, such as Figure 4 As shown, the saw head assembly 2 has an interface card 21 that can be detachably connected to the top of the first battery 41 or the top of the rod assembly 3.
[0026] In other embodiments, such as Figure 2 As shown, the pole assembly 3 includes a top section pole 31, a middle section pole 32, and a bottom section pole 33 that are detachably connected in sequence. The top section pole 31 has a mounting base 34 that is detachably connected to the interface bracket 21 at its top end, and a battery bracket 35 for mounting the second battery 42 is fixed at its bottom end. The power cord is located inside the top section pole 31, and its two ends are connected to the power supply interface of the battery bracket 35 and the power supply interface of the saw head assembly 2, respectively. When handheld operation is required, the first battery 41 is inserted into the interface bracket 21; when high-branch operation is required, the mounting base 34 is inserted into the interface bracket 21.
[0027] In specific embodiments, such as Figure 3 and Figure 4 As shown, it also includes a rotating mechanism 5 that drives the saw head assembly 2 to rotate. The rotating mechanism 5 includes a connecting plate 51 fixed to the top of the top section rod 31, and a drive motor 52 mounted on the connecting plate 51. The power output shaft of the drive motor 52 passes through the connecting plate 51 and is fixed to the mounting base 34.
[0028] It should be noted that in this embodiment, the battery holder 35 is installed at the bottom end of the top section rod 31. Alternatively, depending on the actual situation, the battery holder 35 can be installed on the middle rod 32 or the bottom section rod 33, and the wires can be laid on the middle rod 32 or the bottom section rod 33 accordingly. When the wires are inside the top section rod 31, the middle rod 32, or the bottom section rod 33, a reserved length is provided to prevent the wires from breaking when the drive motor 52 drives the saw head assembly 2 to rotate.
[0029] Meanwhile, to increase battery life, battery holders 35 can be installed at appropriate positions on the top rod 31, middle rod 32, and bottom rod 33; thus, multiple second batteries 42 can be configured, which can be determined according to actual needs.
[0030] In a specific example, such as Figure 5 As shown, the bottom section rod 33 is a fiberglass rod, and the outer wall of the bottom section rod 33 has an insulating umbrella skirt 331 and a silicone grip 332, and its interior is filled with polyurethane foam material.
[0031] More specifically, the bottom section rod 33 is an S-grade fiberglass rod, while the middle section rod 32 and the top section rod 31 are made of high-strength fiberglass composite material or other lightweight insulating materials. This achieves the weight reduction of the tool while ensuring overall insulation performance and structural strength. At the same time, there are multiple middle sections 32. In this embodiment, there are two middle sections 32. The specific number of middle sections 32 is determined according to the actual working height requirements.
[0032] In some examples, such as Figure 5 As shown, a U-shaped retaining ring 36 is detachably connected to the bottom section rod 33, and a remote control switch 6 is installed on the U-shaped retaining ring 36.
[0033] In a specific example, such as Figure 1 As shown, the equipment box 1 integrates a power module 11, a battery charging base 12, and a remote control switch placement slot 13 for the remote control switch 6.
[0034] More specifically, the equipment box 1 has an external charging port. When charging, it prioritizes charging the first battery 41 and the second battery 42. After the batteries are fully charged, it charges the power module 11. Charging stops automatically, thus ensuring that all power sources in the kit are fully charged and ensuring continuous operation.
[0035] In some specific examples, such as Figure 1 As shown, there are two battery charging docks 12, which charge the first battery 41 and the second battery 42 respectively.
[0036] In other embodiments, such as Figure 1 As shown, the equipment box 1 has two battery placement slots 14 that respectively accommodate the first battery 41 and the second battery 42.
[0037] In a specific example, such as Figure 1 As shown, the equipment box 1 contains a lubricating oil adding funnel 15.
[0038] More specifically, each of the equipment boxes 1 has a slot for mounting the aforementioned components, which can prevent the components from shifting. After the components are placed in the corresponding slots, an isolation pad can also be laid to effectively prevent bumps and scratches.
[0039] It should be noted that the saw head assembly 2 is existing technology, and its structure and working principle are the same as existing technology, so it will not be described again here.
[0040] Furthermore, such as Figure 6 As shown, the saw head assembly 2 integrates a safety switch 22, a power display screen 23, and an alarm 24 on its housing. The safety switch 22 is used to turn off the remote control receiver function when the saw head is handheld, preventing accidental activation of the saw head due to accidental touch of the remote control, thus providing foolproof protection. The power display screen 23 is used to display the remaining power of the current power supply battery (first battery 41 or second battery 42) in real time, making it convenient for the user to estimate the continuous working time. The alarm 24 is a proximity warning device. When the saw head assembly 2 approaches a live conductor (such as a high-voltage wire), it will emit an audible and visual alarm to remind the operator to pay attention to safety.
[0041] The pruning kit of this utility model is based on a modular design and a dual-mode power supply system, which enables quick switching between handheld and high-branch operation scenarios.
[0042] 1. Handheld operation mode: When it is necessary to trim branches on the ground or at low elevations, the user takes out the first battery 41 from the battery slot 14 in the equipment box 1, aligns it directly with and inserts it into the interface slot 21 on the saw head assembly 2, completing the mechanical locking and electrical connection. At this time, the saw head assembly 2 constitutes a complete independent handheld chainsaw. The user can operate it by holding the handle of the saw head assembly 2 and directly control the sawing through the trigger switch on it. In this mode, the safety switch 22 can be activated to disable the remote control function to ensure safety.
[0043] 2. High-branch operation mode: When it is necessary to prune branches at higher elevations, the first step is to assemble the equipment: Rod assembly: Take out the bottom rod 33, the required number of intermediate rods 32, and the top rod 31 from equipment box 1. Connect them end to end using quick-connect structures (such as threads or clips) at both ends and lock them in place. The silicone grip 332 on the bottom rod 33 is the main gripping part.
[0044] Power Connection: Install the second battery 42 into the battery holder 35 at the bottom of the top section rod 31. The pre-embedded wires inside the top section rod 31 electrically connect the battery holder 35 to the top mounting base 34. Saw Head Connection: Connect and lock the top of the assembled rod assembly (i.e., the mounting base 34) to the interface holder 21 at the bottom of the saw head assembly 2. At this time, the electrical energy of the second battery 42 is transmitted to the saw head assembly 2 through the wires inside the top section rod 31 to power it (see...). Figure 2 Accessory installation: Secure the remote control switch 6 to the bottom rod 33 using the U-shaped retaining ring 36 at a position convenient for thumb operation.
[0045] During operation, the user holds the handle portion of the bottom section 33 and controls the start and stop of the saw head assembly 2 via the remote control switch 6. When the cutting angle needs to be adjusted, the corresponding button on the remote control switch 6 controls the drive motor 52 of the rotating mechanism 5 to operate. The drive motor 52 drives the mounting base 34 and the saw head assembly 2 fixed thereon to rotate together, achieving an angle adjustment from 0-90° (see...). Figure 4 This allows for easy cutting in multiple directions, including horizontal and diagonal cuts.
[0046] 3. Insulation and safety assurance: When operating in high-pole mode, especially in environments where there may be proximity to live power lines, the multiple insulation structures of the bottom section pole 33 play a crucial role. Its fiberglass material, internal polyurethane foam filling, and outer insulating skirt 331 together form a robust primary insulation barrier, ensuring effective isolation of the operator from high-potential areas. Simultaneously, the warning device 24 integrated into the saw head assembly 2 monitors the surrounding electric field in real time, providing proactive early warnings and offering dual protection for operational safety.
[0047] 4. Energy Management and Maintenance: During outdoor operations, the power module 11 and battery charging base 12 integrated in the equipment case 1 can charge either the first battery 41 or the second battery 42. Dedicated storage slots (battery storage slot 14, remote control switch storage slot 13) within the equipment case 1 ensure that all components are stored in an orderly manner. For routine maintenance, lubricating oil can be easily added to the saw chain of the saw head assembly 2 via the lubrication funnel 15 to keep the equipment in good condition.
[0048] Through the modular combination and intelligent control described above, this kit achieves efficient management of the entire process, from portable storage, rapid deployment, flexible operation to safe maintenance.
