Description

Technical Field

[0001] This utility model relates to the field of garden power tools technology, and in particular to a handheld part and a pruning machine. Background Technology

[0002] Pruning machines, as a gardening tool, are widely used for trimming shrubs, hedges, and other vegetation. Traditional pruning machines are generally powered by fuel or an external power source. Fuel-fired pruning machines emit large amounts of exhaust fumes into the air during operation, polluting the environment and causing significant noise pollution. Externally powered pruning machines, on the other hand, require frequent movement of the power cord, which is very inconvenient.

[0003] Currently, handheld pruning machines have emerged on the market, such as the cordless handheld pruning shears disclosed in Chinese utility model patent CN208300394U. These pruning machines are powered by a portable battery pack, which then drives the pruning blades through a power mechanism. To ensure continuous operation, the battery packs of these pruning machines are typically designed to be detachable, allowing for easy replacement when the battery is depleted. The overall structure of these pruning machines is elongated, with a large portion of the volume concentrated in the rear handheld section, especially the main handle. Because the battery pack's installation space is located between the maximum width and maximum length of the handheld section, even if the battery pack is removed, the overall packaging dimensions of the machine remain largely unchanged, resulting in high packaging and transportation costs—a persistent transportation challenge that needs to be addressed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a handheld part and a pruning machine. The main handle, which occupies a large amount of space on the main unit, is designed to be detachable, thereby effectively reducing the size of the handheld part and laying the foundation for optimizing the packaging size of the pruning machine, thus saving transportation costs.

[0005] The technical solution to achieve the purpose of this utility model is:

[0006] A handheld device includes a main unit, an auxiliary handle, a main handle, and a battery pack. The auxiliary handle is detachably mounted on the front end of the main unit, the main handle is detachably mounted on the rear end of the main unit, and the battery pack is detachably mounted on the main handle.

[0007] Furthermore, a receiving space is formed between the bottom of the main handle and the rear end of the main unit, and the battery pack is located in the receiving space. By reasonably arranging the position of the main handle, a receiving space for placing the battery pack is formed between its bottom and the rear end of the main unit, making the overall structure after assembly compact.

[0008] Furthermore, the rear end of the main unit is provided with a slot, and the front end of the main handle is provided with a plug that is compatible with the slot. The main handle is inserted into the slot through the plug to form a whole with the main unit, and a locking structure is connected between the main unit and the main unit.

[0009] Furthermore, the slot is an upward-opening T-shaped slot, and the insert is inserted into the slot from top to bottom.

[0010] Furthermore, the rear end of the main unit is provided with a first positioning platform and a second positioning platform extending upward and towards the main handle, respectively, located above and below the slot. The front end of the main handle is provided with an extension adapted to the first positioning platform, located above the insertion block, and its bottom is attached to the second positioning platform.

[0011] Furthermore, the second positioning platform is provided with a first through hole extending in the vertical direction, and the main handle is provided with a second through hole corresponding to the first through hole. The locking structure includes a locking screw and a locking nut fixed in the main handle and located at the first through hole. One end of the locking screw is fixedly connected to a knob, and the other end passes through the first through hole and the second through hole and is tightened on the locking nut.

[0012] Furthermore, the upper surface of the second positioning platform is provided with a positioning groove, and the bottom of the main handle is provided with a positioning protrusion that matches the positioning groove.

[0013] Furthermore, the positioning groove is coaxially arranged with the first through hole, which is convenient to process and can directly achieve coaxial alignment between the first through hole and the second through hole, reducing assembly errors.

[0014] Furthermore, the main handle is equipped with a control button for controlling the start and stop of the main unit, and the main handle is equipped with a micro switch for connecting or disconnecting the circuit of the control button. The trigger end of the micro switch is located above the top of the locking screw and is linked with it. When the locking screw is tightened, the micro switch is triggered by the top of the locking screw to make the control button work.

[0015] Furthermore, a battery slide is detachably mounted on the main handle by screws. A locking groove is provided at the opening of the battery slide. The battery pack is provided with a sliding part that matches the battery slide. The sliding part is provided with a locking button that matches the locking groove. The battery pack slides into the battery slide through the sliding part and connects to the main handle. It is then locked into the locking groove by the locking button and fixed to the battery slide.

[0016] Furthermore, the main unit has symmetrical mounting parts on both sides, and the auxiliary handle is a C-shaped handle with the opening facing downwards, with the two free ends respectively mounted on the corresponding mounting parts by screws.

[0017] A pruning machine includes a handheld part as described above, the front end of which is provided with a pruning knife and a baffle. The main unit is provided with a drive assembly electrically connected to a battery pack. The pruning knife is drivenly connected to the drive assembly. The baffle is detachably mounted on the front end of the main unit by screws.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects:

[0019] (1) This utility model changes the traditional structure where the main handle, which occupies a large space on the handheld part, cannot be separated from the main unit. By designing the main handle to be detachably installed on the main unit, the main handle can be removed during packaging and transportation, thereby effectively reducing the size of the handheld part and laying the foundation for optimizing the packaging size of the pruning machine, thus saving transportation costs. In addition, the battery pack can be detachably installed on the main handle, which can ensure the continuous operation of the main unit by replacing the battery pack, while further saving packaging space. The battery pack can be disassembled and packaged, making the transportation packaging design more flexible.

[0020] (2) This utility model achieves rapid assembly through slot and plug structure, and is equipped with a locking structure, which ensures the reliability of the assembly connection between the main handle and the host, while improving the assembly efficiency.

[0021] (3) The slot of this utility model adopts an upward-opening T-shaped slot, which is not only simple in structure, but also fully considers that the height dimension of the rear end face of the host is significantly greater than the width dimension, ensuring that the slot has a sufficiently large depth, thereby increasing the contact surface between the host and the main handle, and further ensuring the reliability of the assembly connection.

[0022] (4) By adding two positioning platforms, the main handle and the main unit can be quickly positioned in the horizontal and vertical directions respectively. At the same time, the second positioning platform plays a supporting role to bear the weight of the main handle and the battery pack, and prevent the slot from deforming and failing due to excessive load.

[0023] (5) The locking structure of this utility model adopts a screw and nut with threaded locking method, which is simple in structure and easy to lock.

[0024] (6) This utility model improves the positioning accuracy during packaging and assembly by adding positioning grooves and positioning protrusions, and facilitates the locking and positioning of the locking structure.

[0025] (7) By adding a micro switch, this utility model ensures that after the main handle is installed on the host, the control button can only be triggered after the locking screw is tightened in place, which prevents the control button from being accidentally triggered when the main handle is just installed on the host and not yet locked, thus preventing accidental injury and improving the safety of use.

[0026] (8) This utility model changes the traditional structure in which the main unit or main handle is equipped with an integrated battery slide. By setting the battery slide and the main handle to be detachable, it provides more convenience for users in later use. More battery packs of different sizes can be matched by replacing the battery slide, making it more flexible to use.

[0027] (9) This utility model achieves a detachable connection between the auxiliary handle and the main unit by using screws. During packaging and transportation, the auxiliary handle can also be disassembled, further saving packaging space. The structure is simple and easy to assemble and disassemble.

[0028] (10) The pruning machine of this utility model adopts a hand-held part that can be detached from the main handle, the auxiliary handle and the battery pack, which greatly reduces the packaging size. At the same time, it is equipped with a detachable baffle, which can block the cutting debris generated when the pruning knife is working, and can also be removed during transport packaging to further reduce the packaging size.

Detailed Implementation

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] (Example 1)

[0041] like Figures 1 to 6 The pruning machine shown includes a handheld unit consisting of a main unit 1, an auxiliary handle 2, a main handle 3, and a battery pack 4. The auxiliary handle 2 is detachably mounted on the front end of the main unit 1, and the main handle 3 is detachably mounted on the rear end of the main unit 1, forming a receiving space between its bottom and the rear end of the main unit 1. The battery pack 4 is located within this receiving space and is detachably mounted on the main handle 3. The front end of the handheld unit is equipped with a pruning blade 100 and a baffle 200. The main unit 1 contains a drive assembly electrically connected to the battery pack 4. The pruning blade 100 is drive-connected to the drive assembly. The baffle 200 is detachably mounted on the front end of the main unit 1 using screws. The entire pruning machine utilizes a handheld unit where the main handle 3, auxiliary handle 2, and battery pack 4 are all detachable, significantly reducing the packaging size. The detachable baffle 200 not only blocks cutting debris generated by the pruning blade 100 during operation but can also be removed during transport packaging, further reducing the packaging size.

[0042] Specifically, the rear end of the main unit 1 is provided with a slot 1-1, and the front end of the main handle 3 is provided with a plug 3-1 that matches the slot 1-1. The main handle 3 is inserted into the slot 1-1 through the plug 3-1 to form a single unit with the main unit 1, achieving quick assembly. A locking structure 5 connects the main handle 3 and the main unit 1, ensuring both the reliability of the assembly connection and improving assembly efficiency. Considering that the height dimension of the rear end face of the main unit 1 is significantly greater than its width dimension, in order to ensure that the slot 1-1 has a sufficiently large depth, the slot 1-1 in this embodiment is an upward-opening T-shaped slot. The plug 3-1 is inserted into the slot 1-1 from top to bottom. While simplifying the structure, it increases the contact surface between the main unit 1 and the main handle 3, further ensuring the reliability of the assembly connection.

[0043] The rear end of the main unit 1 is provided with a first positioning platform 1-2 and a second positioning platform 1-3 extending upward and towards the main handle 3, respectively, located above and below the slot 1-1. The front end of the main handle 3 is provided with an extension 3-2 adapted to the first positioning platform 1-2, located above the insertion block 3-1, and its bottom is in contact with the second positioning platform 1-3. By adding two positioning platforms, the main handle 3 and the main unit 1 can be quickly positioned in the horizontal and vertical directions, respectively. At the same time, the second positioning platform 1-3 serves as a load-bearing structure to support the weight of the main handle 3 and the battery pack 4, preventing the slot 1-1 from deforming and failing due to excessive load.

[0044] The second positioning platform 1-3 has a first through hole 1-4 extending vertically, and the main handle 3 has a second through hole 3-3 corresponding to the first through hole 1-4. The locking structure 5 includes a locking screw 5-1 and a locking nut 5-2 fixed in the main handle 3 and located at the first through hole 1-4. One end of the locking screw 5-1 is fixedly connected to a knob 5-3, and the other end passes through the first through hole 1-4 and the second through hole 3-3 and is tightened onto the locking nut 5-2. The structure is simple and locking is convenient. To facilitate quick coaxial positioning of the two through holes, this embodiment has a positioning groove 1-5 on the upper surface of the second positioning platform 1-3, and a positioning protrusion 3-4 adapted to the positioning groove 1-5 is provided at the bottom of the main handle 3. The positioning groove 1-5 is coaxially set with the first through hole 1-4, which is convenient to process and can directly realize the coaxial alignment of the first through hole 1-4 and the second through hole 3-3, reducing assembly errors.

[0045] The main handle 3 is equipped with a control button 6 for controlling the start and stop of the main unit 1. The main handle 3 also contains a micro switch 7 for connecting or disconnecting the circuit containing the control button 6. The trigger end of the micro switch 7 is located above and linked to the top of the locking screw 5-1. When the locking screw 5-1 is tightened, the micro switch 7 is triggered by the top of the locking screw 5-1, enabling the control button 6 to function normally, thus controlling the start and stop of the main unit 1. By adding the micro switch 7, after the main handle 3 is assembled with the main unit 1, the control button 6 can only be triggered after the locking screw 5-1 is fully tightened, preventing accidental triggering of the control button 6 when the main handle 3 is first installed on the main unit 1 and not yet locked, thus improving safety.

[0046] The main unit 1 has symmetrical mounting parts 1-6 on both sides. The auxiliary handle 2 is a C-shaped handle with the opening facing downwards, and the two free ends are respectively mounted on the corresponding mounting parts 1-6 by screws to achieve detachable connection.

[0047] In existing pruning machines, each main unit can only use a single type of battery pack, which limits user convenience. Therefore, structural optimization of the existing handheld mechanism is necessary. Specifically, a battery slide 8 is detachably mounted on the bottom of the main handle 3 via screws. The bottom of the battery slide 8 has a locking groove 8-1 at its opening. The top of the battery pack 4 has a sliding part 4-1 that matches the battery slide 8. The sliding part 4-1 has a locking button 4-2 that matches the locking groove 8-1. The battery pack 4 slides into the battery slide 8 via the sliding part 4-1 and connects to the main handle 3, and is then secured to the battery slide 8 via the locking button 4-2. By changing the traditional structure where the battery slide is integrated with the main unit or main handle, and making the battery slide 8 and main handle 3 detachable, greater convenience is provided for users. The battery slide 8 can be replaced to accommodate more battery packs of various sizes, making it more flexible in use.

[0048] This invention changes the traditional structure where the auxiliary handle 2 and main handle 3 of the handheld part are inseparable from the main unit 1. By designing the auxiliary handle 2 and main handle 3 to be detachably mounted on the main unit 1, the main handle 3 and auxiliary handle 2 can be removed during packaging and transportation, thereby effectively reducing the overall size of the handheld part. This lays the foundation for optimizing the packaging size of the pruning machine, thus saving transportation costs. At the same time, by rationally arranging the position of the main handle 3, a space for accommodating the battery pack 4 is formed between its bottom and the rear end of the main unit 1, making the overall structure compact after assembly. In addition, the battery pack 4 can be detachably mounted on the main handle 3, which can ensure the continuous operation of the main unit 1 by replacing the battery pack 4, while further saving packaging space. The battery pack 4 can be disassembled and packaged, making the transportation packaging design more flexible.

[0049] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
