[0090] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0091] In this application, the terms "comprises," "comprising," "having," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0092] In this application, the term "and / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0093] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0094] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0095] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0096] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0097] In this application, the terms "controller," "processor," "central processing unit," "CPU," and "MCU" are used interchangeably. Where a unit "controller," "processor," "central processing unit," "CPU," or "MCU" is used to perform a particular function, unless otherwise specified, the function may be performed by a single unit or multiple units.

[0098] In this application, the terms "device", "module" or "unit" can be implemented in the form of hardware or software to achieve specific functions.

[0099] In this application, the terms "calculate", "judge", "control", "determine", "identify", etc. refer to the operations and processes of a computer system or similar electronic computing device (e.g., controller, processor, etc.).

[0100] Reference Figures 1 to 14 This embodiment provides a multi-purpose garden tool system, comprising a first multi-purpose garden tool and a second multi-purpose garden tool. The first multi-purpose garden tool comprises a first accessory interface and a first power unit 300, wherein the first accessory interface is used to attach a working device 200; the first power unit 300 is used to drive the working device 200.

The working device 200 is detachably adapted to at least one of the first accessory interface and the second accessory interface, and at least one of the first and second multi-purpose garden tools is a wheeled tool. The first power unit 300 and the second power unit may be the same or different.

[0101] The above-mentioned setting realizes the applicability of the working device 200 to different types of garden tools, especially the switching between handheld and wheeled tools. Multiple working devices 200 in the same system can be presented in the state of handheld tools or wheeled tools, which greatly compensates for the isolation of working scenes in related technologies and can flexibly respond to different working conditions. While taking into account work flexibility, it can also improve work efficiency and reduce work intensity.

[0102] In the above embodiment, Figure 13 As shown, at least one of the first multi-purpose garden tool and the second multi-purpose garden tool is a wheeled tool. Wheeled tools can be pushed by hand or driven by themselves while moving to perform tasks such as cleaning and cutting. They are more suitable for scenarios with heavy workloads or heavy working devices.

[0103] In some embodiments, at least one of the first multi-purpose garden tool and the second multi-purpose garden tool is a handheld tool. Handheld tools are easy to operate and flexible, and are suitable for use in smaller areas or when aerial work is required. Aerial work refers to work performed above ground level.

[0104] The above-mentioned setting enables the multi-purpose garden tool system including the above-mentioned first multi-purpose garden tool and the second multi-purpose garden tool to meet various work scenarios, flexibly respond to different working conditions, and while taking into account work flexibility, it can also improve work efficiency and reduce work intensity.

A power supply device is provided on the handle 160. The power supply device includes a battery pack, which is placed in the battery compartment 400.

[0106] In some embodiments, the first multi-purpose garden tool can be adapted to at least two of the multiple working devices 200. This configuration enables the first multi-purpose garden tool to handle a variety of tasks while requiring only one first power unit 300. This, to a certain extent, saves space occupied by the first multi-purpose garden tool and reduces costs. Accordingly, the second multi-purpose garden tool can be adapted to at least two of the multiple working devices 200. Some working devices 200 can be adapted to both the first and second multi-purpose garden tools.

[0107] Regarding the working device 200, in some embodiments, the multiple working devices 200 include one or more of the following working devices 200: a soil turning head, a sweeping brush, a rubber brush, a grass trimming head, a trimming head, and a snow shovel head. In other embodiments, the working device 200 can also be set to other structures according to actual work needs, and is not limited to the above structure. Figure 1 As shown, the first multi-purpose garden tool is a wheeled tool, and the working device 200 assembled thereon is a soil turning head; Figure 13 As shown, the first multi-purpose garden tool is a wheeled tool, and the working device 200 assembled thereon is a sweeping brush; Figure 14 As shown, the second multi-purpose garden tool is a handheld tool, and the working device 200 equipped therewith is a soil turning head.

[0108] To improve work efficiency, in some embodiments, the first multi-purpose garden tool includes a first battery pack, which is used to provide power to the first power unit 300. The energy range of the first battery pack is 150Wh-900Wh. Alternatively, the energy range of the first battery pack is 150Wh-650Wh. In some embodiments, the energy range of the first battery pack is 300Wh, 350Wh, 360Wh, 370Wh, 380Wh, 390Wh, 400Wh, 450Wh, or 490Wh.

[0109] In some embodiments, the second multi-purpose garden tool includes a second battery pack for providing electrical energy to the second power unit, and the energy range of the second battery pack is 150Wh-900Wh. Alternatively, the energy range of the second battery pack is 150Wh-650Wh. In some embodiments, the energy range of the first battery pack is 300Wh, 350Wh, 360Wh, 370Wh, 380Wh, 390Wh, 400Wh, 450Wh, or 490Wh.

[0110] The maximum output power of the first multi-purpose garden tool ranges from 300W to 5000W. Alternatively, the maximum output power of the first multi-purpose garden tool ranges from 300W to 3500W. Alternatively, the maximum output power of the first multi-purpose garden tool ranges from 300W to 2500W. Alternatively, the maximum output power of the first multi-purpose garden tool ranges from 300W to 1800W. This configuration can adapt to different working environments. For smaller working areas and lower efficiency requirements, a lower maximum output power, such as 350W, 400W, or 500W, can be selected. For larger working areas and higher efficiency requirements, a higher maximum output power, such as 1200W, 1800W, 2000W, 2500W, 3500W, or 4500W, can be selected. Furthermore, depending on the type of working device 200 installed, the maximum output power of the first multi-purpose garden tool can vary accordingly to suit the structure of the working device 200 and the corresponding working conditions. Accordingly, the maximum output power of the second multi-purpose garden tool ranges from 300W to 5000W. Alternatively, the maximum output power of the second multi-purpose garden tool ranges from 300W to 3500W. Alternatively, the maximum output power of the second multi-purpose garden tool ranges from 300W to 2500W. Alternatively, the maximum output power of the second multi-purpose garden tool ranges from 300W to 5000W. The method for selecting the maximum output power of the second multi-purpose garden tool is described above.

[0111] In some embodiments, in order to improve the degree of automation and ease of use, the multi-purpose garden tool system includes a detachable battery pack, which is used to provide electrical energy for at least the first power unit 300. Alternatively, the battery pack provides electrical energy for at least the second power unit of the second multi-purpose garden tool. In some embodiments, the first multi-purpose garden tool and the second multi-purpose garden tool can be detachably connected to the battery pack, respectively, and the battery packs installed on the first multi-purpose garden tool and the second multi-purpose garden tool can be the same or different. The provision of a detachable battery pack makes the battery pack easy to replace, reducing subsequent maintenance costs. In some embodiments, either the first multi-purpose garden tool or the second multi-purpose garden tool can also be powered by a battery pack.

[0112] In some embodiments, the battery pack can be adapted to at least one of a first multi-purpose garden tool and a second multi-purpose garden tool. In some embodiments, the same battery pack can be adapted to a first multi-purpose garden tool equipped with various types of working devices 200. In other embodiments, the same battery pack can be adapted to a first multi-purpose garden tool equipped with some types of working devices 200, while other battery packs can be adapted to a first multi-purpose garden tool equipped with other types of working devices 200. Correspondingly, in still other embodiments, the same battery pack can also be adapted to a second multi-purpose garden tool equipped with various types or some types of working devices 200. In still other embodiments, the same battery pack can be adapted to both the first multi-purpose garden tool and the second multi-purpose garden tool.

[0113] In some embodiments, the multi-purpose garden tool system includes a telescopic rod, through which the working device 200 is connected to the first accessory interface or the second accessory interface. The length of the telescopic rod can be adjusted to accommodate different installation requirements of the multi-purpose garden tool, adapt to different working conditions, and stabilize the center of gravity.

[0114] This embodiment also provides a working device suitable for a multi-purpose garden tool system, which includes a first multi-purpose garden tool and a second multi-purpose garden tool; the first multi-purpose garden tool includes a first accessory interface and a first power device 300, wherein the first power device 300 includes at least a first motor 310, and the first motor 310 is used to output power; the second multi-purpose garden tool includes a second accessory interface and a second power device; the second power device includes at least a second motor, and the second motor is used to output power; the working device suitable for the multi-purpose garden tool system includes a connection port that is detachably adapted to the first accessory interface or the second accessory interface; at least one of the first multi-purpose garden tool or the second multi-purpose garden tool is a wheeled tool.

[0115] The above-mentioned setting realizes the applicability of the working device 200 to different types of garden tools by selectively detachably assembling multiple working devices 200 to the first accessory interface of the first multi-purpose garden tool or the second accessory interface of the second multi-purpose garden tool, especially the switching between handheld and wheeled tools. Multiple working devices 200 in the same system can present the state of both handheld tools and wheeled tools, which greatly compensates for the isolation of working scenes in related technologies, allowing the working device 200 to flexibly respond to different working conditions. While taking into account work flexibility, it can also improve work efficiency and reduce work intensity.

[0116] In some embodiments, the multi-purpose garden tool system further includes a telescopic rod having an extended state and a retracted state; when the first multi-purpose garden tool is a wheeled tool, the working device 200 can be connected to the first accessory interface of the first multi-purpose garden tool through the telescopic rod in the retracted state.

[0117] If the second multi-purpose garden tool is a handheld tool, the working device 200 can be connected to the second accessory interface of the second multi-purpose garden tool via a telescopic rod in an extended state. The length of the telescopic rod in the retracted state is shorter than that in the extended state. When the working device 200 is attached to a wheeled tool, the spacing requirements between the working device 200 and the tool accessory interface differ from those when attached to a handheld tool. Some handheld tools require a relatively long spacing, while some wheeled tools require a relatively short spacing. Connecting via a telescopic rod effectively solves this problem in the present multi-purpose garden tool system.

[0118] In some embodiments, the telescopic rod includes an outer sleeve and an inner rod, the inner rod being disposed within the outer sleeve and capable of axial relative movement. The inner rod and the outer sleeve are threadedly connected. A locking member is used to lock the inner rod and the outer sleeve. Specifically, the locking member is a locking screw that passes through a threaded hole in the outer sleeve and abuts the inner rod. The telescopic structure of the telescopic rod can adopt embodiments described in related art. The specific structure can be appropriately configured based on actual circumstances and is not specifically limited.

[0119] This embodiment also provides a multi-purpose garden tool, comprising a wheel assembly 500, a first power unit 300, a plurality of working devices 200, and a first battery pack. The wheel assembly 500 includes wheels 520 rotatable about a wheel axis, used to support the multi-purpose garden tool while it travels on the ground. The first power unit 300 includes at least a first motor 310. Selectable ones of the plurality of working devices 200 are detachably connected to the first power unit 300 and driven by the first motor 310 to perform corresponding functions of the multi-purpose garden tool. The first battery pack supplies power to the first motor 310. The first battery pack can be located in front of the first motor 310 in the front-to-back direction and / or below the output shaft of the first motor 310 in the top-to-bottom direction. The wheel assembly 500 also includes a wheel bracket 510, with two wheels 520 spaced apart in the left-right direction and rotatably mounted on the wheel bracket 510.

[0120] like Figure 6As shown, the above arrangement enables the working devices 200 to be detachably attached to the first power unit 300 of the multi-purpose garden tool, adapting them to different application scenarios. This addresses the isolation of working scenarios in the related art, allowing the working device 200 to flexibly respond to different working conditions. This allows for flexibility while also improving work efficiency and reducing workload. The arrangement of the first battery pack in front of the first motor 310 in the fore-aft direction and below the output shaft of the first motor 310 in the up-down direction allows the distribution of the working devices, first battery pack, and first power unit 300 in the multi-purpose garden tool to more effectively stabilize the center of gravity.

[0121] In the front-to-back direction, the center of gravity G2 of the first battery pack can be located in front of the wheel 520, and in the top-to-bottom direction, the center of gravity G2 of the first battery pack can also be located above the wheel 520. Positioning the center of gravity G2 of the first battery pack above the wheel 520 helps improve the installation position of the first battery pack, avoiding the risk of the first battery pack touching the ground during operation of the multi-purpose garden tool, thereby improving the safety of the first battery pack during use.

[0122] In some embodiments, in the front-to-back direction, the first motor 310 is located behind the wheel 520. The above arrangement helps to properly balance the weight of the multi-purpose garden tool and can improve the convenience of lifting the front working device 200 off the ground with the wheel 520 as the fulcrum.

[0123] The working device 200 includes a working head 210 and a connecting tube 220 connected to the working head 210. The connecting tube 220 is detachably connected to the first power unit 300. In the fore-aft direction, the first battery pack is at least partially positioned between the working head 210 and the wheels 520. This arrangement improves the convenience of connecting the working device 200 and the first power unit 300. The positioning of the first battery pack helps control the center of gravity G1 of the multi-purpose garden tool, thereby reducing effort during use.

[0124] In some embodiments, the first battery pack is located below the connecting pipe 220 of the working device 200. The above arrangement helps to lower the center of gravity G2 of the first battery pack and improve the stability of the multi-purpose garden tool.

[0125] In the front-back direction, the center of gravity G1 of the multi-purpose garden tool is located between the working head 210 of the working device 200 and the wheels 520. The above arrangement ensures that the working device 200 and the wheels 520 are in contact with the ground without the need for hand support and can remain stable.

[0126] Furthermore, the distance between the center of gravity G1 of the multi-purpose garden tool and the first battery pack is smaller than the distance between the first battery pack and the wheel 520 .

[0127] In some embodiments, the multi-purpose garden tool further includes a second battery pack that is detachably mounted on the multi-purpose garden tool; the second battery pack is used to power the first motor 310. Furthermore, the second battery pack can also power other power tools after being detached.

[0128] The first battery pack and the second battery pack are arranged in parallel. In some embodiments, the first battery pack and the second battery pack are connected in parallel or in series to simultaneously power the first motor 310. It should be noted that the first battery pack and the second battery pack are independent battery packs rather than battery cells within the battery pack.

[0129] Regarding the energy of the first battery pack, in some embodiments, the energy range of the first battery pack is 150Wh-900Wh. Alternatively, the energy range of the first battery pack is 150Wh-650Wh. Specifically, the energy of the first battery pack can be 160Wh, 170Wh, 180Wh, 190Wh, 200Wh, 300Wh, 500Wh, or 800Wh.

[0130] To improve the safety of the first battery pack, the multi-purpose garden tool includes a battery compartment 400 , and the first battery pack is detachably installed in the battery compartment 400 .

[0131] In some embodiments, the battery compartment 400 includes a compartment body 410 and a compartment cover 420 covering an opening of the compartment body 410 , and the first battery pack can be inserted into the compartment body 410 .

[0132] The opening of the compartment body 410 is tilted upward, and the first battery pack can be inserted into the compartment body 410 along the downward tilt direction. The above arrangement enables the first battery pack to be carried in the compartment body 410 and is easy to take out and put in.

[0133] In some embodiments, a multi-purpose garden tool is further provided, comprising a wheel set 500, a first power device 300, a power supply device, and a plurality of working devices 200, wherein the wheel set 500 comprises a wheel 520 rotatable about a wheel axis for supporting the multi-purpose garden tool to walk on the ground; the first power device 300 comprises at least a first motor 310; the power supply device comprises at least one battery pack to supply power to the first motor 310; the multi-purpose garden tool further comprises a plurality of working devices 200, wherein one of the plurality of working devices 200 is detachably connected to the first power device 300 and driven by the first motor 310 to perform corresponding functions of the multi-purpose garden tool; in the front-to-back direction, the center of gravity G2 of the battery pack is located in front of the wheel axis.

[0134] like Figure 6As shown, this arrangement allows for the removable attachment of one of the multiple working devices 200 to the first power unit 300 of the multi-purpose garden tool, enabling the working device 200 to adapt to different application scenarios. This addresses the isolation of working scenarios in the related art, allowing the working device 200 to flexibly respond to diverse working conditions. This allows for both flexibility and improved efficiency while reducing workload. The placement of the battery pack's center of gravity G2 forward of the wheel axis in the fore-aft direction makes the arrangement of the wheels, working devices, first battery pack, and first power unit 300 in the multi-purpose garden tool more user-friendly.

[0135] In some embodiments, a multi-purpose garden tool is further provided, comprising a frame 100, a wheel set 500, a first power device 300, a power supply device and a plurality of working devices 200, wherein the wheel set 500 is connected to the frame 100, the wheel set 500 includes a wheel 520 rotatable around a wheel axis, and the wheel 520 is used to support the multi-purpose garden tool to walk on the ground; the first power device 300 includes at least a first motor 310; one of the plurality of working devices 200 is detachably connected to the first power device 300 and driven by the first motor 310 to perform corresponding functions of the multi-purpose garden tool; the power supply device includes at least one battery pack to supply power to the first motor 310; in the front-to-back direction, the center of gravity G1 of the multi-purpose garden tool is located in front of the wheel axis, and the first motor 310 is located behind the wheel axis.

[0136] This arrangement allows for the removable attachment of one of the multiple working devices 200 to the first power unit 300 of the multi-purpose garden tool, enabling the working devices 200 to adapt to different application scenarios. This addresses the isolation of working scenarios in related technologies, enabling the working device 200 to flexibly respond to diverse working conditions. This allows for both flexibility and improved efficiency while reducing workload. The placement of the battery pack's center of gravity G2 in front of the wheels 520 in the fore-aft direction facilitates adjustment of the overall center of gravity G1.

[0137] The working device 200 includes a working head 210 and a connecting tube 220 connected to the working head 210. The connecting tube 220 is detachably connected to the first power unit 300. The battery pack is located below the connecting tube 220 of the working device 200 in the vertical direction. This arrangement helps lower the center of gravity G2 of the battery pack and improve the stability of the multi-purpose garden tool.

[0138] The center of gravity G1 of the multi-purpose garden tool is located forward of the center of gravity G2 of the battery pack. This arrangement ensures that even when the battery pack is removed, the multi-purpose garden tool remains stable thanks to the support of the working device 200 and wheels 520, thereby improving the stability of the multi-purpose garden tool and facilitating battery pack replacement.

[0139] In some embodiments, the battery pack is detachably connected to the rack 100. The above arrangement improves the convenience of subsequent maintenance and helps reduce maintenance costs.

[0140] The power supply device includes a plurality of battery packs, and the plurality of battery packs supply power to the first motor 310. The models of the plurality of battery packs may be the same or different.

[0141] like Figure 2 As shown, in some embodiments, the multi-purpose garden tool further includes an operating device 110, which is provided for user support and for controlling the operating state of the first motor 310. The provision of the operating device 110 facilitates control of the operating state of the multi-purpose garden tool. The operating device 110 includes an electronic switch 111, a speed dial 112, a control handle 113, and an unlock button 114. The electronic switch 111 and the speed dial 112 can implement functions such as mode switching of the first power device 300 and speed adjustment of the first motor 310. The control handle 113 and the unlock button 114 are used to start the multi-purpose garden tool. Specifically, the unlock button 114 can be pressed first and then the control handle 113 can be pushed.

[0142] The operating device 110 includes two extension rods 115, which are rotatably connected to the frame 100 via the extension rods 115, allowing the operating device 110 to have an operational storage position and an operational working position. This arrangement facilitates storage of the multi-purpose garden tool when the operating device 110 is in the storage position, reducing space usage. The frame 100 is provided with mounting holes, and the two extension rods 115 are clamped to either side of the frame 100. The extension rods 115 are provided with fixing holes. Fixing screws 116 pass through the fixing holes and the mounting holes and are screwed into fixing nuts 117, thereby clamping the two extension rods 115 to the left and right sides of the frame 100.

[0143] This embodiment also provides a multi-purpose garden tool, including a wheel set 500, a first power device 300, a power supply device and multiple working devices 200, wherein the wheel set 500 includes a wheel 520 that can rotate around a wheel axis, and the wheel 520 is used to support the multi-purpose garden tool to walk on the ground; the first power device 300 includes at least a first motor 310; one of the multiple working devices 200 is detachably connected to the first power device 300 and driven by the first motor 310 to perform the corresponding function of the multi-purpose garden tool; the power supply device includes at least one battery pack to supply power to the first motor 310; in the front-to-back direction, the center of gravity G1 of the multi-purpose garden tool is located in front of the center of gravity G2 of the battery pack; the total energy of the power supply device is greater than or equal to 150Wh and less than or equal to 900Wh.

[0144] like Figure 6As shown, the above arrangement enables the working device 200 to be adapted to different application scenarios by selectively detachably assembling one of the multiple working devices 200 to the first power device 300 of the multi-purpose garden tool, thereby compensating for the isolation of working scenarios in the related art, and enabling the working device 200 to flexibly respond to different working conditions. While taking into account work flexibility, it can also improve work efficiency and reduce work intensity. The arrangement in which the center of gravity G1 of the multi-purpose garden tool is located in front of the center of gravity G2 of the battery pack allows the multi-purpose garden tool to remain stable under the support of the working device 200 and the wheels 520 even if the battery pack is removed, thereby improving the stability of the multi-purpose garden tool and the convenience of replacing the battery pack. The range limitation of the energy of the power supply device provides a variety of options to adapt to different application scenarios.

[0145] This embodiment further provides a multi-purpose garden tool, comprising a frame 100, a wheel assembly 500, a first power unit 300, and a plurality of working devices 200. The wheel assembly 500 is connected to the frame 100 and includes wheels 520 rotatable about a wheel axis. The wheels 520 are used to support the multi-purpose garden tool to move on the ground. The first power unit 300 includes at least a first motor 310. One of the plurality of working devices 200 is detachably connected to the first power unit 300 and driven by the first motor 310 to perform corresponding functions of the multi-purpose garden tool.

[0146] The multi-purpose garden tool also includes a power supply device, which includes at least one battery pack to supply power to the first motor 310; in the front-to-back direction, the distance L1 between the center of gravity G1 of the multi-purpose garden tool and the wheel axis is greater than or equal to 0 mm and less than or equal to 300 mm; the maximum output power of the working device 200 is greater than or equal to 300 W and less than or equal to 5000 W.

[0147] This arrangement, by allowing one of multiple working devices 200 to be detachably attached to the first power unit 300 of the multi-purpose garden tool, allows the working device 200 to be adapted to different application scenarios. This overcomes the isolation of working scenarios in the related art, allowing the working device 200 to flexibly respond to different working conditions. While ensuring operational flexibility, it also improves work efficiency and reduces workload. The multi-purpose garden tool's center of gravity G1 helps minimize the difficulty of lifting the working device 200 off the ground. The limited maximum output power of the working device 200 provides users with multiple options to adapt to different application scenarios.

[0148] This embodiment also provides a multi-purpose garden tool, including a wheel set 500, a first power device 300 and a plurality of working devices 200, wherein the wheel set 500 includes a wheel 520 rotatable around a wheel axis, and the wheel 520 is used to support the multi-purpose garden tool to walk on the ground; the first power device 300 includes at least a first motor 310; one of the plurality of working devices 200 is detachably connected to the first power device 300 and is configured to be driven by the first motor 310 to perform the corresponding function of the multi-purpose garden tool; the multi-purpose garden tool also includes a first locking member 120 and a second locking member 130 for locking or releasing the working device 200; the first power device 300 can be removed when the first locking member 120 and the second locking member 130 are both in a released state.

[0149] The above arrangement enables the working device 200 to be adapted to different application scenarios by selectively detachably attaching one of the multiple working devices 200 to the first power device 300 of the multi-purpose garden tool. This addresses the isolation of working scenarios in the related art, allowing the working device 200 to flexibly respond to different working conditions. While ensuring work flexibility, it also improves work efficiency and reduces work intensity. The provision of the first locking member 120 and the second locking member 130 helps to improve the connection convenience between the first power device 300 and the working device 200. The provision of the first locking member 120 and the second locking member 130 also improves the convenience of assembly and disassembly of the first power device 300.

[0150] like Figure 4 、 Figure 5 As shown, the working device 200 includes a working head 210 and a connecting tube 220 connected to the working head 210. The first locking member 120 and the second locking member 130 act on the connecting tube 220 of the working device 200. The connecting tube 220 of different working devices 200 has the same structure. This arrangement allows different working devices 200 to use the first locking member 120 and the second locking member 130.

[0151] In some embodiments, the multi-purpose garden tool includes a battery pack to provide power to the first power unit 300. The first locking member 120 and the second locking member 130 are both positioned above the battery pack. The battery pack improves the automation and ease of use of the multi-purpose garden tool. The positioning of the battery pack and the two locking members facilitates easy installation of the battery pack.

[0152] Specifically, at least one of the first locking member 120 and the second locking member 130 is a quick-clamping device. Both the first locking member 120 and the second locking member 130 are quick-clamping devices. The first locking member 120 includes a sleeve 121 having a slit 1211. A through-hole is provided on one side of the sleeve 121 and the slit 1211, and a locking screw hole is provided on the other side. A first screw 122 passes through the through-hole and is screwed into the locking screw hole. The first screw 122 can shrink the slit 1211 of the sleeve 121, allowing the sleeve 121 to tightly wrap around the connecting tube 220.

[0153] The second locking member 130 includes a fixing seat 131 and a pressure plate 132. One side of the pressure plate 132 is hinged to the fixing seat 131 and can rotate between an open position and a locked position. When the pressure plate 132 is in the locked position, it can press the connecting tube 220 between the fixing seat 131 and the pressure plate 132. The fixing seat 131 is provided with a fixing screw hole, and the other side of the pressure plate 132 is provided with a through hole. When the pressure plate 132 is in the locked position, a second screw 133 passes through the through hole and is screwed into the fixing screw hole to fix the pressure plate 132 to the fixing seat 131, thereby pressing the connecting tube 220.

[0154] In some embodiments, the multi-purpose garden tool further includes a height adjustment device 140 that is capable of adjusting the wheel assembly 500 between a wheel operating position and a wheel storage position. When the wheel assembly 500 is in the wheel storage position, the wheels 520 are not in contact with the ground. This arrangement helps reduce the space occupied by the multi-purpose garden tool when stored.

[0155] Specifically, the height adjustment device 140 includes a support rod 141, one end of which is hinged to the frame 100 of the multi-purpose garden tool, and the wheel assembly 500 is hinged to the other end of the support rod 141. The support rod 141 swings to drive the wheel assembly 500 to switch between the wheel working position and the wheel storage position. The support rod 141 is connected to the wheel bracket 510 of the wheel assembly 500.

[0156] The height adjustment device 140 also includes a transmission rod 142 and an adjustment rod 143. A transmission portion is provided in the middle of the support rod 141. One end of the transmission rod 142 is hinged to the transmission portion. An adjustment portion is provided in the middle of the adjustment rod 143. The adjustment rod 143 is hinged to the frame 100 at the adjustment portion. One end of the adjustment rod 143 is hinged to the other end of the transmission rod 142. Turning the other end of the adjustment rod 143 rotates the adjustment rod 143, which in turn drives the support rod 141 to swing through the transmission rod 142. This arrangement enables the adjustment wheel assembly 500 to switch between the wheel operating position and the wheel storage position.

[0157] To ensure the positional reliability of the wheel assembly 500, in some embodiments, the height adjustment device 140 includes a locking member 144 that can lock the wheel assembly 500 in at least the wheel operating position or the wheel storage position. Specifically, the frame 100 is provided with a locking plate 145, which is provided with a plurality of locking holes 1451. The locking member 144 is a pin, and the adjustment rod 143 is provided with an adjustment hole. The locking member 144 can be inserted into the adjustment hole and selectively inserted into one of the plurality of locking holes 1451. In one embodiment, the adjustment portion is provided with an adjustment hole, and the adjustment pin 1431 is provided through the adjustment hole and the frame 100, so that the adjustment rod 143 is hinged to the frame 100. The locking hole 1451 is provided around the outer circumference of the adjustment pin 1431. There are three locking holes 1451, corresponding to the three positions of the wheel assembly 500 relative to the frame 100. Specifically, the wheel assembly 500 has a wheel operating position, an intermediate position, and a wheel storage position. The intermediate position is located at the wheel operating position and wheel storage position bracket. When the wheel assembly 500 is in the wheel operating position, the height of the multi-purpose garden tool is higher than when the wheel assembly 500 is in the intermediate position. When the wheel assembly 500 is in the intermediate position, the height of the multi-purpose garden tool is higher than when the wheel assembly 500 is in the wheel storage position.

[0160] In the above-described embodiment, data transmission between the controller of the power supply device and the identification element of the working device 200 is performed via electronic circuitry disposed within the connecting tube 220. In some embodiments, the identification element is disposed in a fixed portion of the working device 200, and two wires may be extended from the identification element to pass through the connecting tube 220. Simultaneously, the controller may also extend two wires to connect to the identification element to obtain the aforementioned data.

[0161] By detachably attaching one of the multiple working devices 200 to the first power unit 300 of the multi-purpose garden tool, this arrangement allows the working device 200 to be adapted to different application scenarios.

This allows for both flexibility and improved efficiency while reducing workload. The identification element allows the controller to determine the type of working device 200 and drive it accordingly to correctly execute the corresponding function of the multi-purpose garden tool.

[0162] The controller obtains the photoelectric parameters of the identification element through the electronic circuitry within the connecting tube 220 to identify the type of the connected working device 200, thereby controlling the working head 210 to perform the corresponding function based on the control method corresponding to the type of working device 200.
