Description

Technical Field

[0001] This utility model relates to the field of garden machinery technology, specifically a low-noise and environmentally friendly electric pruning shears structure. Background Technology

[0002] Traditional pruning shears are mostly manual, resulting in high labor intensity and low efficiency. Pruning high branches requires ladders and other tools, posing safety hazards. While gasoline-powered pruning shears offer high power, they cause significant noise pollution and exhaust emissions, failing to meet environmental protection requirements. Existing electric pruning shears often have relatively fixed structures, limited extension functions, or unreliable connections and unstable signal transmissions, making it difficult to meet the demands of precise, efficient, and low-noise pruning of branches at different heights and angles in complex gardening operations. Furthermore, the efficiency of the transmission structure and the ease of blade adjustment need improvement. Therefore, there is an urgent need for a modular, low-noise, reliable, and flexible electric pruning tool. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a low-noise and environmentally friendly electric pruning shear structure, which solves the problems of high noise, inability to flexibly adapt to different pruning heights and angles, unreliable electrical connections, and low transmission efficiency in existing pruning shears.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A low-noise, environmentally friendly electric pruning shear structure includes: The handle unit contains a power source for providing rotational power. The extension rod is detachably connected to the handle unit and electrically connected to the power source via an internal electrical connection assembly. The cutter head unit includes a moving blade and a fixed blade. The moving blade reciprocates relative to the fixed blade to achieve shearing. The transmission unit is installed inside the handle unit. Its input end is connected to the output shaft of the power source, and its output end is rotatably connected to a flexible connector, which is rotatably connected to the moving blade.

[0005] This utility model's low-noise, environmentally friendly electric pruning shears structure, through its standardized extension rod design and reliable locking mechanism, allows users to flexibly assemble different numbers of extension rods according to the actual working height, greatly expanding the working range. The electrical connector with U-shaped conductive springs provides continuous and stable contact pressure, effectively avoiding poor contact or power outages caused by vibration. The meshing structure of the locking teeth and the adjusting bolts enables stepless adjustment and quick locking of the blade unit angle. The electric drive combined with a flexible transmission shaft replaces the high-noise gasoline engine or pneumatic mechanism. The flexible connector can adapt to the bending and angle changes of the extension rod, efficiently transmitting power to the blade.

[0006] Preferably, the power source is an electric actuator, and the handle unit also includes a battery compartment in which a battery pack is detachably installed, and the battery pack supplies power to the power source.

[0007] Preferably, the extension rod includes a plug at the top, a socket at the bottom, and a locking mechanism fitted onto the outer wall of the socket. The plug and socket are fixed by the locking mechanism after being inserted.

[0008] Preferably, the locking mechanism includes a locking sleeve fitted onto the outer wall of the socket and a spring connecting the locking sleeve and the socket.

[0009] Preferably, the outer wall of the socket is fitted with a locking ball, and the locking sleeve has a protrusion that abuts against the locking ball to form a locked state, and a groove that accommodates the locking ball to form an unlocked state.

[0010] Preferably, the electrical connection assembly includes a conductive core located at the bottom of the socket and a conductive spring located at the top of the plug, the conductive spring being in a U-shaped state when in a free-stretching state.

[0011] Preferably, the electrical connection assembly also includes a control switch disposed on the outer wall of the extension rod for controlling the start / stop and / or speed of the power source.

The cutter head unit also includes a locking tooth fixedly connected to the outer wall of the moving blade and a locking tooth that engages with the locking tooth. The locking tooth is engaged and fixed to the handle unit by the fixing bolt.

[0013] This invention provides a low-noise, environmentally friendly electric pruning shear structure. It has the following beneficial effects: 1. With its standardized extension rod design and reliable locking mechanism, users can flexibly assemble different numbers of extension rods according to the actual working height, greatly expanding the working range. Its advantage lies in the fact that a single pair of pruning shears can handle different pruning scenarios, from low shrubs to tall trees, offering strong versatility and reducing users' equipment purchase costs.

[0014] 2. The use of electrical connectors with U-shaped conductive springs provides continuous and stable contact pressure, effectively avoiding poor contact or power outages caused by vibration. Its benefits include ensuring the stability of signal and power transmission, guaranteeing the continuity and controllability of pruning operations, and improving user experience and operational safety.

[0015] 3. Through the meshing structure of the locking teeth and the adjusting bolt, the angle of the cutter head unit can be steplessly adjusted and quickly locked. Its beneficial effect is that it allows the pruning angle to precisely match the growth direction of the branches, enabling more accurate and labor-saving pruning, thus improving pruning quality and efficiency.

[0019] 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.

[0020] Example: like Figure 1-6 As shown, this utility model embodiment provides a low-noise and environmentally friendly electric pruning shears structure, with a handle unit 1, which is internally equipped with a power source for providing rotational power; The extension rod 2 is detachably connected to the handle unit 1 and electrically connected to the power source via its internal electrical connection component 3; The cutter head unit 4 includes a moving blade 41 and a fixed blade 42. The moving blade 41 reciprocates relative to the fixed blade 42 to achieve shearing. The transmission unit 5 is installed inside the handle unit 1. Its input end is connected to the output shaft of the power source, and its output end is rotatably connected to a flexible connector 51. The flexible connector 51 is rotatably connected to the moving blade 41.

[0021] This utility model's low-noise, environmentally friendly electric pruning shears, through a standardized design of the extension rod 2 and a reliable locking mechanism 23, allows users to flexibly assemble different numbers of extension rods 2 according to the actual working height, greatly expanding the working range. Its advantages lie in the fact that one pruning shear can handle different pruning scenarios, from low shrubs to tall trees, offering strong versatility and reducing the user's equipment purchase costs. The electric push rod drive, combined with a flexible connector 51, replaces the high-noise gasoline engine or pneumatic mechanism. The flexible connector 51 can adapt to the bending and angle changes of the extension rod 2, efficiently transmitting power to the blade head. Its advantages include significantly reduced overall machine noise, high transmission efficiency, and low energy loss.

[0022] Furthermore, in another embodiment, the power source is an electric actuator, and the handle unit 1 also includes a battery compartment in which a battery pack is detachably installed, and the battery pack supplies power to the power source.

[0023] Because the low-noise and environmentally friendly electric pruning shears of this utility model have the above structure, the battery pack provides power, and each extension rod 2 can be connected in parallel through the electrical connection component 3 after assembly, so that each extension rod 2 can control the power source.

[0024] Furthermore, in another embodiment, the extension rod 2 includes a top plug 21 and a bottom socket 22, as well as a locking mechanism 23 sleeved on the outer wall of the socket 22. After the plug 21 and the socket 22 are inserted, they are fixed by the locking mechanism 23.

[0025] The locking mechanism 23 includes a locking sleeve 231 fitted on the outer wall of the socket 22 and a spring 232 connected between the locking sleeve 231 and the socket 22.

[0026] The outer wall of the socket 22 is fitted with a locking ball 233, and the locking sleeve 231 has a protrusion that abuts against the locking ball 233 to form a locked state, and a groove that accommodates the locking ball 233 to form an unlocked state.

[0027] Because of the above-mentioned structure, the low-noise and environmentally friendly electric pruning shears of this utility model have the following features: the extension rod 2 is made of carbon fiber, making it lightweight and sturdy. The electrical connectors at both ends are gold-plated to prevent corrosion. The locking mechanism 23's locking sleeve 231 operates smoothly, and the spring 232 provides sufficient preload. The user inserts the plug 21 of one extension rod into the socket 22 of the other, slides it down, and releases the locking sleeve 231; a secure connection is achieved with a "click," and the electrical circuit is automatically established.

[0028] Furthermore, in another embodiment, the electrical connection assembly 3 includes an electrical conductive core 31 located at the bottom of the socket 22 and a conductive spring 32 located at the top of the plug 21, the conductive spring 32 being in a U-shaped state in a free extension and retraction state.

[0029] The electrical connection assembly 3 also includes a control switch 33 disposed on the outer wall of the extension rod 2 for controlling the start / stop and / or speed of the power source.

[0030] Because the low-noise, environmentally friendly electric pruning shears of this invention have the above-mentioned structure, and employ an electrical connector with a U-shaped conductive spring 32, they provide continuous and stable contact pressure, effectively avoiding contact problems or power outages caused by vibration. Its beneficial effects include ensuring the stability of signal and power transmission, guaranteeing the continuity and controllability of pruning operations, improving user experience and operational safety. Each extension rod 2 has a control switch 33 after assembly, facilitating remote operation of the cutter head unit 4.

[0031] Furthermore, in another embodiment, the fixed blade 41 is rotatably connected to the side wall at the top of the handle unit 1, and the moving blade 42 is rotatably connected to the fixed blade 41 by a detachable pin. The outer wall of the handle unit 1 is also threaded with a fixing bolt 11. The blade unit 4 also includes a locking tooth 43 fixedly connected to the outer wall of the moving blade 42 and a locking tooth 44 engaging with the locking tooth 43. The locking tooth 44 is engaged and fixed to the handle unit 1 by the fixing bolt 11.

[0032] Because the low-noise and environmentally friendly electric pruning shears of this invention have the above-mentioned structure, when it is necessary to adjust the angle of the fixed blade 41, the fixing bolt 11 is removed, the locking tooth 44 is released from locking the locking tooth 43, thereby adjusting the fixed blade 41. After adjustment, the locking tooth 44 locks the locking tooth 43, thus fixing the fixed blade 41. Through the meshing structure of the locking tooth 44 and the locking tooth 44, combined with the adjusting bolt, stepless adjustment and quick locking of the blade unit angle are achieved. Its beneficial effect is that it enables the pruning angle to accurately match the growth direction of the branches, allowing for more precise and labor-saving pruning, thus improving pruning quality and efficiency.
