Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garden tools, and more particularly to a pruning kit with hand-held operation and high-branch operation functions. BACKGROUND

[0002] High-altitude tree branch pruning operations are widely used in many fields such as tree pruning, garden maintenance, municipal management, and power line maintenance. There are various high-altitude tree branch pruning tools in the prior art, but they have deficiencies in portability and operation mode flexibility, which are specifically manifested in: 1. Single function of the tool, which cannot quickly adapt to different operation scenarios. Existing market products are usually single in form: either a hand-held electric saw suitable for ground operation but unable to reach high places, or a fixed-length high-branch saw that can be extended but is heavy and cannot be disassembled and converted into a portable hand-held mode. The operator needs to carry multiple tools to deal with tree branches at different heights, which is cumbersome to manage and cannot achieve efficient operation with "one set of tools, two methods".

[0003] 2. Poor operation experience in high-branch operation mode, laborious and unstable control; existing high-branch electric saws mostly use fixed or simple extendable designs, and the driving battery is usually fixedly installed at the saw head or the top of the rod. This layout causes the center of gravity of the entire tool to be seriously high and forward. The operator needs to continuously exert a large torque to counteract gravity to stabilize the saw head, making the control laborious, the rod body shaking violently, and the cutting precision difficult to control, which not only greatly increases the labor intensity but also brings safety hazards of operation instability.

[0004] Therefore, how to provide a highly integrated pruning kit that can quickly switch between portable handheld and stable high-branch operation modes and has both functions is a problem that needs to be solved by those skilled in the art. SUMMARY

[0005] Therefore, the present application provides a pruning kit with hand-held operation and high-branch operation functions, aiming to solve the above technical problems.

[0006] In order to achieve the above purpose, the present application adopts the following technical solutions: A pruning kit with hand-held operation and high-branch operation functions, comprising an equipment box, and a saw head assembly, a rod body assembly and a power supply unit integrated inside the equipment box; The rod body assembly comprises 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 for being mounted on the saw head assembly to realize power supply for handheld operation; or, a plurality of the rod segments are connected and detachably connected with the saw head assembly, the second battery is used for being mounted on any rod segment and connected with a power supply interface of the saw head assembly through an electric wire to realize power supply for high branch operation.

[0007] Through the technical scheme, the pruning kit with handheld operation and high branch operation functions is provided, the core components are integrally stored and carried through the equipment box, the problems of dispersed tool components and inconvenient management are effectively solved, the technical basis that a set of tools can flexibly switch two operation modes is realized through at least two detachable rod segments and the design of the double batteries with different capacities, when the first battery is directly used for power supply, a portable handheld electric saw is formed, when the second battery is used for power supply through the rod body, an extendable high branch electric saw is formed, one set of tools realizes two uses, and the operation adaptability and efficiency are greatly improved.

[0008] Preferably, in the pruning kit with handheld operation and high branch operation functions, the saw head assembly has an interface card seat detachably connected with the first battery or the top end of the rod body assembly. The standardized mechanical and electrical interfaces are arranged on the saw head assembly, the interface card seat is a key hub for realizing quick and reliable mode switching, the mounting / dismounting of the first battery and the connection / separation of the whole rod body assembly become simple, intuitive and firm, and the usability and reliability of the kit are improved.

[0009] Preferably, in the pruning kit with handheld operation and high branch operation functions, the rod body assembly includes a top rod, an intermediate rod and a bottom rod which are sequentially detachably connected, the top end of the top rod has a mounting seat detachably connected with the interface card seat, and the bottom end of the top rod is fixed with a battery card seat for mounting the second battery, the electric wire is located in the top rod, and the two ends of the electric wire are respectively connected with the power supply interface of the battery card seat and the power supply interface of the saw head assembly. The optimal composition mode (top, middle and bottom three segments) of the rod body assembly is specified. The core is the integrated design of the top rod: the top end is connected with the saw head, the bottom end is integrated with the second battery mounting seat, and the internal electric wire is provided. This design moves the battery from the traditional saw head position to the rod body in the high branch operation mode, reduces the center of gravity of the whole tool system, makes the operation more labor-saving and stable during high branch operation, and improves the operation experience; meanwhile, the integrated power supply line avoids the winding and damage risk of the exposed electric wire.

[0010] Preferably, in the pruning kit with both handheld operation and high-branch operation functions, a rotating mechanism is further included for driving the saw head assembly to rotate, the rotating mechanism comprising a connecting plate fixed to the top end of the top section rod and a driving motor installed on the connecting plate, and a power output shaft of the driving motor penetrating through the connecting plate and being fixed to the mounting seat. The saw head is added with an electric angle adjustment function, and the driving motor is remotely controlled to drive the saw head to rotate in a horizontal plane, so as to realize accurate and remote adjustment of the sawing angle. This makes the operator not need to frequently move or adjust the posture of the rod body, and can efficiently complete multi-angle cutting tasks such as horizontal cutting and inclined cutting, especially in a complex tree crown environment, which greatly improves the operation flexibility, accuracy and safety.

[0011] Preferably, in the pruning kit with both handheld operation and high-branch operation functions, the bottom section rod is a glass fiber rod, the outer side wall of the bottom section rod is provided with an insulating umbrella skirt and a silica gel handle, and the inside of the bottom section rod is filled with polyurethane foaming material. Double insulation protection is provided. First, the glass fiber is used as the rod body base material. Second, the closed-cell polyurethane foaming material is filled in the rod, which not only enhances the bending strength of the rod body, but also further blocks the possible internal electrical path. The insulating umbrella skirt on the outer side increases the creepage distance. This structure jointly constitutes a multi-layer insulation barrier from the inside to the outside, which greatly improves the safety in high humidity environment or operation near live lines.

[0012] Preferably, in the pruning kit with both handheld operation and high-branch operation functions, a U-shaped clasp is detachably connected to the bottom section rod, and a remote control switch is installed on the U-shaped clasp. Through the U-shaped clasp, the remote control switch can be quickly installed at any suitable position on the bottom section rod (near the part held by the operator), and the operator's thumb can be conveniently controlled. The detachable connection mode also facilitates adjustment or removal according to personal habits, and optimizes the human-machine interaction experience.

[0013] Preferably, in the pruning kit with both handheld operation and high-branch operation functions, a power supply module, a battery charging seat and a remote control switch placement area are integrated in the equipment box. The energy supply system is deeply integrated into the storage equipment box. The integrated power supply module (mobile power supply) can charge the battery on site. The integrated battery charging seat provides a convenient charging interface. The remote control switch placement area realizes the orderly management of accessories. This design upgrades the simple packaging box to a mobile charging station and workstation, solving the endurance anxiety and equipment management problems of outdoor operation.

[0014] Preferably, in the pruning kit with hand-held operation and high-branch operation functions, the number of the battery charging bases is two, and the two battery charging bases are used for charging the first battery and the second battery respectively. Providing independent dedicated charging bases for the first battery (hand-held mode) and the second battery (high-branch mode) allows the two batteries to be charged at the same time, maximally shortens the battery supply cycle, and guarantees the demand for high-intensity and continuous operation.

[0015] Preferably, in the pruning kit with hand-held operation and high-branch operation functions, two battery placing grooves for accommodating the first battery and the second battery respectively are arranged in the equipment box. The two batteries with different capacities and different purposes are designed with exclusive storage positions in the equipment box, which ensures that the batteries do not collide and wear each other during transportation and storage, and can be quickly positioned and used, embodying the delicacy and humanization of the kit design.

[0016] Preferably, in the pruning kit with hand-held operation and high-branch operation functions, a lubricating oil adding funnel is integrated in the equipment box. The lubricating oil adding funnel facilitates the operator to lubricate and maintain the saw head assembly at any time, prolongs the service life of the tool, maintains the optimal cutting performance, avoids the situation that the operation is affected due to forgetting to carry the maintenance tool, and improves the completeness and convenience of the kit.

[0017] According to the above technical solution, compared with the prior art, the pruning kit with hand-held operation and high-branch operation functions has the following beneficial effects: 1. The pruning kit with high integration provided by the present application effectively solves the problems of dispersion and fragmentation of traditional high-altitude pruning tool systems. The saw head, detachable rod body, dual-mode power supply unit and all accessories are integrated in a single equipment box, realizing the integration of multiple dispersed tools. This design enables the operator to quickly and flexibly switch between the portable hand-held electric saw and the stable and extended high-branch electric saw according to the needs on site, greatly improving the operation adaptability and deployment efficiency.

[0018] 2. The present application optimizes the distribution of the tool's center of gravity by moving the power supply battery in the high-branch mode to the lower part of the rod body, effectively moving the center of gravity of the tool in the high-branch mode, making the operation more labor-saving and stable. The rotation mechanism integrated in the saw head supports remote precise adjustment of the cutting angle, enhancing the operation flexibility and precision. At the same time, the rod body with a multi-layer composite insulation structure (such as glass fiber base material, internal foaming filling and external umbrella skirt) provides safety protection far beyond that of traditional single-layer insulation rod bodies for operation in complex or live-line environments.

[0019] 3、The mobile power supply, intelligent charging management module are deeply integrated in the storage equipment box, a self-sustaining energy supply system is constructed, and the field endurance bottleneck is effectively solved.

[0039] It should be noted that the saw head assembly 2 is a prior art, and its structure and working principle are the same as those of the prior art, which will not be described here.

[0040] Further, as shown in Figure 6 The housing of the saw head assembly 2 is integrated with a protection switch 22, an electric quantity display screen 23, and a pre-warning device 24. The protection switch 22 is used to turn off the remote control receiving function when handheld operation is performed, so as to prevent accidental start of the saw head caused by accidental touch of the remote controller, thereby playing a fool-proof protection role. The electric quantity display screen 23 is used to display the remaining electric quantity of the current power supply battery (the first battery 41 or the second battery 42) in real time, thereby facilitating the user to estimate the sustainable operation time. The pre-warning device 24 is a near-electricity pre-warning device, which will issue an audible and visual alarm when the saw head assembly 2 approaches a live body (such as a high-voltage conductor), thereby reminding the operator to pay attention to safety.

[0041] The pruning kit of the embodiment of the present application realizes quick switching between handheld and high-branch operation scenes based on the modular design and the dual-mode power supply system.

[0042] 1. Handheld operation mode: When ground or low-branch pruning is needed, the user takes the first battery 41 from the battery placing groove 14 of the equipment box 1, directly aligns and inserts it into the interface card seat 21 on the saw head assembly 2, and completes mechanical locking and electrical connection. At this time, the saw head assembly 2 constitutes a complete and independent handheld electric saw. The user can hold the handle of the saw head assembly 2 to operate and directly control sawing through the trigger switch thereon. In this mode, the protection switch 22 can be enabled to disable the remote control function to ensure safety.

[0043] 2. High-branch operation mode: When high-branch pruning is needed, the following assembly is performed: Rod assembly: The bottom rod 33, the required number of intermediate rods 32, and the top rod 31 are taken out from the equipment box 1. They are connected end to end through the quick connection structure (such as threads or buckles) at both ends and locked. The silica gel handle 332 on the bottom rod 33 is the main holding position.

[0044] Power connection: Install the second battery 42 to the battery card seat 35 at the bottom end of the top section rod 31, and the pre-embedded wire inside the top section rod 31 has electrically connected the battery card seat 35 with the mounting seat 34 at the top end. Saw head connection: Dock and lock the top end of the assembled rod body assembly (i.e. the mounting seat 34) with the interface card seat 21 at the bottom of the saw head assembly 2. At this time, the electric energy of the second battery 42 is transmitted to the saw head assembly 2 through the wire inside the top section rod 31 to supply power for it (see Figure 2 ). Accessory installation: Fix the remote control switch 6 to the bottom section rod 33 at a position convenient for thumb operation through the U-shaped clasp ring 36.

[0045] During operation, the user holds the handle part of the bottom section rod 33 and controls the start and stop of the saw head assembly 2 through the remote control switch 6. When the cutting angle needs to be adjusted, the corresponding key on the remote control switch 6 is controlled to work the driving motor 52 of the rotating mechanism 5, the driving motor 52 drives the mounting seat 34 and the saw head assembly 2 fixed thereon to rotate together to realize the angle adjustment of 0-90° (see Figure 4 ), so as to easily complete the cutting in multiple directions such as horizontal and inclined directions.

[0046] 3. Insulation and safety guarantee: When operating in the high branch mode, especially in the environment that may be adjacent to a live line, the multiple insulation structures of the bottom section rod 33 play a key role. The glass fiber material, the internally filled polyurethane foaming material and the insulating umbrella skirt 331 on the outside jointly constitute a strong main insulation barrier to ensure the effective isolation of the operator from the high potential end. At the same time, the early warning device 24 integrated in the saw head assembly 2 monitors the surrounding electric field in real time to provide active early warning and double protection for the safety of operation.

[0047] 4. Energy management and maintenance: During outdoor operation, the power module 11 and the battery charging seat 12 integrated in the equipment box 1 can charge the first battery 41 or the second battery 42. The special placement grooves (battery placement groove 14, remote control switch placement groove 13) in the equipment box 1 ensure the orderly storage of all components. During daily maintenance, the saw chain of the saw head assembly 2 can be conveniently lubricated through the lubricating oil adding funnel 15 to keep the equipment in good condition.

[0048] Through the above modular combination and intelligent control, this kit realizes the efficient management of the whole process from portable storage, rapid deployment, flexible operation to safe maintenance.

[0049] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same and similar parts between the various embodiments can be referred to each other. For the device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the related parts can be referred to the method part.
