[0027] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings.

[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] When using power tools for aerial work, users often need to carry the power tools with them while climbing or moving, so they can use them at any time after reaching their target location. Furthermore, to ensure operational safety, power tools often need to be connected to a safety rope to prevent falls. To facilitate aerial work, related art power tools are equipped with two receiving members, one for connecting a safety rope and the other for connecting a self-locking hook. This allows the power tool to be attached to a safety belt or fixed location even after being released from the user's hands, preventing it from falling and reducing safety hazards. Furthermore, the self-locking hook allows the power tool to be attached to a safety belt or waist belt, freeing the user's hands while climbing or moving. However, when connecting the safety rope and the self-locking hook, they often interfere with each other, hindering the self-locking hook's hooking and unhooking operation while the power tool is connected to the safety rope. The interference from the safety rope makes it difficult for the user to connect the self-locking hook to the corresponding receiving member, or to connect the safety rope even when the self-locking hook is connected, resulting in inconvenient operation.

[0030] To solve the above problems, the present application proposes an electric tool. Exemplarily, the electric tool may be a chain saw, an electric drill, an electric hammer, etc. A chain saw is used as an example for detailed description below.

[0031] like Figure 1 and Figure 2 As shown, the power tool 2 includes a main body housing 10, a working assembly 20, a motor 30, and a battery pack 40. The working assembly 20 is configured to perform a task; the motor 30 is disposed within the main body housing 10 and is configured to drive the working assembly 20 to perform the task; and the battery pack 40 is disposed within the main body housing 10 and is configured to provide power to the motor 30.

[0032] like Figure 3As shown, the power tool is further provided with a first hanging ring 50 and a second hanging ring 60 ; the first hanging ring 50 and the second hanging ring 60 are configured to connect the power tool 2 to an external component.

[0033] Among them, Figure 2 and Figure 3 As shown, the power tool 2 includes a length extension direction (X direction in the figure), a height extension direction (Z direction in the figure) and a width extension direction (Y direction in the figure) when the working component 20 is in the working state, and the length extension direction, the height extension direction and the width extension direction are perpendicular to each other.

[0034] The battery pack 40, the motor 30, and the working component 20 are arranged in sequence along the length extension direction; the working component 20 is installed at one end of the main body shell 10 in the length extension direction, and the first hanging ring 50 and the second hanging ring 60 are installed at the other end of the main body shell 10 away from the working component 20 in the length extension direction.

[0035] The working component and the first hanging ring 50 and the second hanging ring 60 are respectively arranged at the two ends of the power tool 2. The lifting position when carrying the power tool 2 is at the first hanging ring 50 and the second hanging ring 60, which improves the convenience of carrying and can also avoid the external connecting components from interfering with the working component 20, thereby improving safety.

[0036] The first hanging ring 50 and the second hanging ring 60 are spaced apart in the width extension direction. Specifically, the first hanging ring 50 is arranged in the first section (M in the figure) in the width extension direction, and the second hanging ring 60 is arranged in the second section (N in the figure) in the width extension direction. The first section and the second section do not overlap and are spaced apart from each other.

[0037] In addition, the first hanging ring 50 and the second hanging ring 60 are spaced apart in the height extension direction. Specifically, the first hanging ring 50 is installed at a first height (P in the figure) in the height extension direction, and the second hanging ring 60 is installed at a second height (Q in the figure) in the height extension direction Z. The first height and the second height do not overlap and are spaced apart from each other.

[0038] The two types of hanging rings are arranged on the main body housing 10 at different width areas and different heights and are spaced apart from each other. When connecting one of the hanging rings, it is possible to avoid interference with the other hanging ring to affect the connection operation.

[0039] It should be noted that the spacing between the first section and the second section in the width extension direction (as shown by G in the figure) makes the first hanging ring 50 connected to the first section and the second hanging ring 60 connected to the second section not intersect with each other in the width extension direction, and the external component connected to the first hanging ring 50 and the external component connected to the second hanging ring 60 also do not intersect with each other in the width extension direction.

[0040] The fact that the first height and the second height do not overlap and are spaced apart from each other can be understood as the first height being greater than the second height, or the first height being less than the second height.

[0041] In a specific embodiment, the working assembly includes a guide bar 211 and a saw chain 212 wound around the guide bar 211, which performs the cutting operation. The main body housing 10 and the working assembly 20 extend in the longitudinal direction X. The working assembly 20 at one end of the main body housing 10 performs the work, while the first and second hanging loops 50 and 60 at the other end of the main body housing are used to connect to external components. The external components apply force to the first and second hanging loops 50 and 60 to lift and carry the entire power tool 2. The power tool 2 can be connected to one external component using the first hanging loop 50, another external component using the second hanging loop 60, or both external components simultaneously, adapting to a variety of usage scenarios and needs.

[0042] For example, in some scenarios, the user may need to work on a tree, such as using a chain saw to prune or remove branches. When climbing a tree, the user can connect the safety rope to one of the hanging rings and transport the power tool 2 to the target location through the safety rope. The user can also connect the other hanging ring to the self-locking hook worn on the user and carry the power tool 2 to the target location. When the user reaches the target location, the user can remove the self-locking hook from the hanging ring and carry the power tool 2 to the target location. When the user needs to move to another location on the tree to work, the user can connect the hanging ring to the self-locking hook worn on the user and carry the power tool 2 to another location. When the user reaches the target location, the user can remove the self-locking hook from the hanging ring and continue to work with the power tool 2. This can free both hands and improve the convenience and safety of the operation. In some embodiments of the present application, such as Figures 2 to 4 As shown, the first hanging ring 50 and the second hanging ring 60 are pivotally connected to the main body housing 10; the first hanging ring 50 pivots around a first pivot axis, and the second hanging ring 60 pivots around a second pivot axis.

[0043] Specifically, the first and second hanging loops 50, 60 are pivotally connected to the main housing 10 and rotate according to the relative position and force relationship between the external component and the main housing 10 to decompose the tensile force applied in the direction of gravity between the external component and the power tool 2. At the same time, the user's relative position with the power tool 2 is uncertain when hanging and removing the loops. By configuring the first and second hanging loops 50, 60 to be pivotally connected, the user can rotate the loops to an appropriate angle, reducing the difficulty of operation when hanging and removing the loops. Furthermore, the first pivot axis is parallel to the second pivot axis; the first height is the height of the first pivot axis; and the second height is the height of the second pivot axis. The pivot axes of the first and second hanging loops 50, 60 are parallel, and the angular ranges of rotation of the first and second hanging loops 50, 60 can be the same or different. The pivot axes of the first hanging ring 50 and the second hanging ring 60 for pivotal motion are at different heights, and the height ranges of their rotation are different. The height range is formed by taking the pivot axis as the rotation center and the maximum distance from the pivot axis in the structure of the first hanging ring 50 or the second hanging ring 60 as the radius, forming its height range in the height extension direction Z.

[0044] In one embodiment, the height range of the first hanging ring 50 does not overlap with the height range of the second hanging ring 60 ; in another embodiment, the height range of the first hanging ring 50 overlaps with the height range of the second hanging ring 60 .

[0045] In a specific embodiment, the pivot axes of the first hanging ring 50 and the second hanging ring 60 extend along the width extension direction. During the rotation of the first hanging ring 50 and the second hanging ring 60, their positions in the height extension direction and the length extension direction change. The first hanging ring 50 and the second hanging ring 60 are spaced apart in the width extension direction, and their positions in the width extension direction do not change. Therefore, no interference occurs during the rotation process.

[0046] In another specific embodiment, the pivot axes of the first hanging ring 50 and the second hanging ring 60 extend along the height extension direction. During the rotation of the first hanging ring 50 and the second hanging ring 60, their positions in the width extension direction and the length extension direction change. The first hanging ring 50 and the second hanging ring 60 are spaced apart in the height extension direction, and their positions in the height extension direction do not change. Therefore, no interference occurs during the rotation process.

[0047] In some embodiments of the present application, the spacing between the first height and the second height in the height extension direction is 0 to 80 mm; the spacing between the first section and the second section in the width extension direction is 0 to 78 mm. In some embodiments, optionally, the spacing between the first height and the second height in the height extension direction is 30 to 40 mm; the spacing between the first section and the second section in the width extension direction is 20 to 30 mm.

[0048] A certain distance is set between the first height and the second height in the height extension direction, and a certain distance is set between the first section and the second section in the width extension direction, so that the operating space of the first hanging ring 50 and the second hanging ring 60 can be separated to avoid interference during operation.

[0049] In a specific embodiment, the spacing between the first height and the second height in the height extension direction can be 0mm, 15mm, 30mm, 35mm, 40mm or 80mm, and the spacing between the first section and the second section in the width extension direction can be 0mm, 10mm, 20mm, 25mm, 30mm, 50mm or 78mm, etc.

[0050] In some embodiments of the present application, the external component includes a safety rope and a self-locking hook; one of the first hanging ring 50 and the second hanging ring 60 is used to connect the safety rope, and the other is used to connect the self-locking hook.

[0051] Specifically, while moving, the user is connected to the safety rope, which ensures their safety. The power tool 2 can also be connected to the safety rope using either the first or second loops 50, 60, and the safety rope can be used to move the power tool 2 to the construction site. When the power tool 2 is ready for use at the construction site, the other of the first or second loops 50, 60, can be connected to the user's wearable device via a self-locking hook, allowing it to move with the user and facilitate operation of the power tool. In actual use, the user can choose any connection method based on mobility requirements, operational needs, or the external environment to ensure convenience and safety.

[0052] In some embodiments of the present application, the main housing 10 includes a left housing and a right housing arranged sequentially along a width direction, and the left housing and the right housing are assembled and connected to form the main housing 10. When a user holds the power tool to perform work, the side closer to the user's body in the width direction is the left, and the side farther away from the user's body is the right.

[0053] Optionally, the first loop 50 is configured to connect to a self-locking hook, and the second loop 60 is configured to connect to a safety rope. In the widthwise direction, the first loop 50 is located to the left of the second loop 60. That is, the first loop 50 is closer to the user's body than the second loop 60. For example, the self-locking hook is typically attached to the user's belt, and the user typically operates the power tool with their right hand. Connecting the self-locking hook by attaching it to the first loop 50, which is closer to the user's body, makes it easier for the user to attach or detach the self-locking hook from the first loop with one hand, facilitating the user's ability to attach or detach the power tool from their belt with one hand.

[0054] In some embodiments of the present application, Figure 3As shown, a separating rib 101 is provided on the main housing 10 between the first hanging ring 50 and the second hanging ring 60. The separating rib 101 protrudes from the surface of the main housing 10 and divides the main housing 10 into a first space for mounting the first hanging ring 50 and a second space for mounting the second hanging ring 60 in the width direction. The separating rib 101 spatially separates the first hanging ring 50 from the second hanging ring 60, thereby preventing external connecting components from interfering with the first hanging ring 50 and the second hanging ring 60. It also facilitates the user to clearly distinguish the first hanging ring 50 from the second hanging ring 60 when attaching or detaching the rings, thereby improving the accuracy of the operation. In addition, the separating rib 101 also serves as a reinforcing support, thereby improving the mounting strength of the two hanging rings on the main housing 10.

[0055] In a specific embodiment, on one end face of the main body shell 10 in the length extension direction, the shell at the middle position protrudes outward, and a concave first space and a second space are formed on both sides of the protruding part, wherein a first hanging ring 50 is set in the first space and a second hanging ring 60 is set in the second space.

[0056] In some embodiments of the present application, Figure 2 and Figure 5 As shown, the main body housing 10 is provided with a first mounting seat 102 for mounting the first hanging ring 50 and a second mounting seat 103 for mounting the second hanging ring 60; the first hanging ring 50 is pivotally connected to the first mounting seat 102; the second hanging ring 60 is pivotally connected to the second mounting seat 103. This realizes the connection between the first hanging ring 50 and the second hanging ring 60 and the main body housing 10.

[0057] In one specific embodiment, both the first mounting seat 102 and the second mounting seat 103 are connected to the dividing rib 101. The first hanging ring 50 and the second hanging ring 60 have pivot axes respectively mounted on the first mounting seat 102 and the second mounting seat 103. The first and second mounting seats 102 and 103 are fixed to the first and second mounting seats 102 and 103 in the widthwise direction, while being able to rotate about the fixed seats. The first and second mounting seats 102 and 103 can be integral with the dividing rib 101, with the first and second mounting seats 102 and 103 formed by projections from the dividing rib 101 on either side in the widthwise direction. Alternatively, the first and second mounting seats 102 and 103 can be inserted into the side surfaces of the dividing rib 101 in the widthwise direction.

[0058] In another specific embodiment, the first mounting seat 102 and the second mounting seat 103 are located on the rear end surface of the power tool 2 in the length extension direction, and the pivot shaft structure for mounting the first hanging ring 50 and the second hanging ring 60 is protruded from the rear end surface or recessed in the rear end surface.

[0059] In some embodiments of the present application, Figure 3As shown, the surface of the host housing 10 is provided with a recessed area 104, and the recessed area 104 is configured to allow at least a portion of the first hanging ring 50 and / or the second hanging ring 60 to be suspended relative to the surface of the host housing 10. As an example, at least a portion of the second hanging ring 60 is suspended relative to the surface of the host housing 10.

[0060] The suspended portion provides operating space for the user. For example, when the user is connecting the external component and the second hanging ring 60, the user can put his hand into the recessed area 104 to flip the second hanging ring 60, making the connection process simple.

[0061] In some embodiments of the present application, Figure 4 As shown, the external component is a self-locking hook; the first hanging ring 50 includes a connecting section and a main body section connected to the connecting section; the first hanging ring 50 is connected to the main body 10 through the connecting section; the first hanging ring is connected to the self-locking hook through the main body section; the main body section includes a first ring section 51 for the self-locking hook to be inserted and a second ring section 53 for the self-locking hook to slide out, the first ring section 51 is connected to the second ring section 53, and a space for the self-locking hook to slide is formed between the first ring section 51 and the second ring section 53.

[0062] Furthermore, in one embodiment, the first ring segment 51 is arranged on the side of the power tool 2 close to the user's body in the use state in the width extension direction, and the first ring segment 51 includes a first bending segment 52; the second ring segment 53 is arranged on the side of the power tool 2 away from the user's body in the use state in the width extension direction Y, and the second ring segment 53 includes a second bending segment 54; the first bending segment 52 and the second bending segment 54 are arranged diagonally.

[0063] By providing the first ring segment 51 and the second ring segment 53, the self-locking hook can be snapped into or slid out of the first hanging ring 50 by one-hand operation. The first bent section 52 is used to abut against the self-locking hook and connect with the self-locking hook, and the second bent section 54 disengages the self-locking hook.

[0064] During operation, the user operates the self-locking hook with one hand, causing it to rest against the first bent section 52 of the first loop section 51 on the side closest to the body, locking it into the sliding space for the self-locking hook, thereby locking the first hanging loop 50 to the self-locking hook. When the self-locking hook slides out of the first hanging loop 50, it applies force to the second bent section 53 of the second loop section 53 on the side away from the body, sliding out of the internal space and completing the separation.

[0065] In a specific embodiment, the first ring segment 51 includes a linear extension portion, and also includes a linear extension portion that extends in another direction after being bent at the first bending segment 52; the second ring segment 53 includes a second bending segment 54, and the second ring segment 53 also includes a linear extension portion extending in two directions from the second bending segment 54, and the first bending segment 52 and the second bending segment 54 are arranged diagonally, so the linear extension portion of the first ring segment 51 and the linear extension portion of the second ring segment 53 also need to be bent and connected, so that the first ring segment 51 and the second ring segment 53 together constitute a linear "R"-shaped ring structure.

[0066] like Figures 6 to 8 The figure shows the second embodiment of the present application. The main structure of the power tool in this embodiment is the same as that of the first embodiment, differing in the specific shape of the first hanging loop 80. In this embodiment, the first hanging loop 80 comprises a first straight segment 81, a first curved segment 82, a second curved segment 84, and a second straight segment 83, which are sequentially connected. The first straight segment 81 and the second straight segment 83 are spaced apart, with the first curved segment 82 located between the extension direction of the first straight segment 81 and the extension direction of the second straight segment 83. The extension direction of the second straight segment 83 divides the space into a side close to the first straight segment 81 and a side away from the first straight segment 81. The second curved segment 84 is located on the side away from the first straight segment 81. This creates an arc-like "R"-shaped ring structure for the first hanging loop 80. This provides a better tactile feel during use, and external components slide more easily within the first hanging loop 80, preventing them from getting stuck and hindering operation.

[0067] During use, the user operates the self-locking hook with one hand, causing it to rest against the first straight segment 81 or the first curved segment 82 on the side closest to the body, locking it into the space provided for the self-locking hook to slide. This locks the hook, connecting the first loop 80 to the self-locking hook. When the self-locking hook slides out of the first loop 80, it applies force to the second curved segment 84 on the side away from the body, sliding it out of the internal space and completing the release.

[0068] like Figure 9 、 Figure 10 and Figure 11 The third embodiment of the present application is shown in FIG. In the third embodiment, the main structure and external components of the power tool are the same as those of the first and second embodiments, differing in the specific shape of the first hanging ring 90. The external component is a self-locking hook; the first hanging ring 90 includes a connecting section and a main section connected to the connecting section; the first hanging ring 90 is connected to the main housing 10 via the connecting section; the first hanging ring 90 is connected to the self-locking hook via the main section; and the main section is configured in a non-closed circular shape.

[0069] Specifically, the main body section includes a circular ring segment 91 with an opening. The two ends of the opening are connected to two straight segments spaced apart and connected to the connecting segment. The structure of the circular ring segment 91 facilitates the sliding of the external component within it, increasing the flexibility of the connection between the first hanging ring 90 and the external component.

[0070] During specific use, the circular ring segment 91 is used for the self-locking hook to be locked in, and part of it is used for the self-locking hook to slide out, thereby realizing the connection process and the disconnection process between the self-locking hook and the first hanging ring 90.

[0071] It should be noted that, in the above embodiments, the first hanging ring 50 is used as an example object, but it is not limited to the first hanging ring 50. The second hanging ring 60 is also applicable to the above embodiments. The first hanging ring 50 and the second hanging ring 60 can be any one of the above embodiments, and the first hanging ring 50 and the second hanging ring 60 can be set to the same shape or different shapes.

[0072] In some embodiments, the first hanging ring 50 and the second hanging ring 60 are made of metal wire. When the power tool falls or is hit, the first hanging ring 50 and the second hanging ring 60 can absorb the impact of the part through elastic deformation and are not easily damaged.

[0073] In some embodiments of the present application, Figure 2 and Figure 8 As shown, the electric tool is a chain saw; the chain saw further includes a main handle 70; the main handle 70 is disposed between the battery pack 40 and the working assembly 20, and is disposed above the main housing 10 in the height extension direction.

[0074] When using the chainsaw, the user pulls the main handle 70. The working assembly 20 utilizes the guide bar 211 and saw chain 212 to perform cutting operations, with the guide bar 211 and saw chain 212 facing the front of the workpiece. The length of the chainsaw is defined by the length of the guide bar 211, the height of the chainsaw is defined by a height direction parallel to the guide bar 211, and the width of the chainsaw is defined by a thickness direction parallel to the guide bar 211. The workpiece end of the guide bar 211 is the front end of the length direction. Therefore, the first hanging loop 50 and / or the second hanging loop 60 are located at the rear end of the chainsaw in the length direction. The first hanging loop 50 and the second hanging loop 60 do not overlap in the width direction or the height direction and are separated by a gap. An external connecting member is connected to the rear end of the chainsaw to facilitate carrying the chainsaw and facilitate the user's single-handed connection and disconnection of the chainsaw from the external member.

[0075] In one embodiment of the present application, Figure 7As shown, a chain saw is also proposed, including a main body housing 10, a cutting assembly 210, a motor 30, a battery pack 40, a main handle 70, and a first hanging ring 50 and a second hanging ring 60.

[0076] The main housing 10 includes a battery pack accommodating portion; the cutting assembly 210 is installed in the main housing 10 and is configured to perform cutting tasks, and the cutting assembly 210 includes a guide plate 211 and a saw chain 212 wound around the guide plate 211; the motor 30 is arranged in the main housing 10 and is configured to drive the cutting assembly 210 to perform cutting tasks; the battery pack 40 is installed in the battery pack 40 accommodating portion and is configured to provide electrical energy to the motor 30; the main handle 70 is for the user to hold, and the first hanging ring 50 and the second hanging ring 60 are arranged between the battery pack 40 and the cutting assembly 210, and are configured to connect the chain saw to an external component.

[0077] The chain saw includes a length extension direction (such as the X direction in the figure), a height extension direction (such as the Z direction in the figure) and a width extension direction (such as the Y direction in the figure), and the length extension direction, the height extension direction and the width extension direction are perpendicular to each other; the length extension direction is configured to be parallel to the length extension direction of the guide plate 211; the height extension direction is configured to be parallel to the height extension direction of the guide plate 211; and the width extension direction is configured to be parallel to the thickness extension direction of the guide plate 211.

[0078] The battery pack 40, motor 30, and cutting assembly 210 are arranged in sequence along the length of the chain saw. The cutting assembly is mounted on one end of the main housing 10 in the lengthwise direction, while the first and second hanging loops 50 and 60 are mounted on the other end of the main housing 10, away from the cutting assembly 210. The cutting assembly 210 and the first and second hanging loops 50 and 60 are located at opposite ends of the chain saw. When the chain saw is carried, the first and second hanging loops 50 and 60 are used for lifting. This improves portability and prevents external connecting components from interfering with the cutting assembly 210, enhancing safety.

[0079] The first hanging ring 50 and the second hanging ring 60 are spaced apart in the width extension direction. Specifically, the first hanging ring 50 is arranged in the first section (M in the figure) in the width extension direction, and the second hanging ring 60 is arranged in the second section (N in the figure) in the width extension direction. The first section and the second section do not overlap and are spaced apart from each other (G in the figure).

[0080] In addition, the first hanging ring 50 and the second hanging ring 60 are spaced apart in the height extension direction. Specifically, the first hanging ring 50 is installed at a first height (such as P in the figure) in the height extension direction, and the second hanging ring 60 is installed at a second height (such as Q in the figure) in the height extension direction Z. The first height and the second height do not overlap and are spaced apart from each other.

[0081] The two hanging loops are arranged at different widths and heights on the main body housing 10 and are spaced apart from each other so that the two hanging loops do not interfere with each other when connected to external components, making it easy to connect or remove external components and convenient operation. For example, when the first hanging loop 50 is connected to the safety rope, the user can reduce the negotiation between the safety rope and the self-locking hook when connecting the second hanging loop 60 to the self-locking hook, which can facilitate the connection of the second hanging loop 60 to the self-locking hook.

[0082] In one embodiment, Figure 6 and Figure 9 The chain saw further comprises an auxiliary handle 71, which is connected to the left side of the main housing in the width extension direction. During operation, the user usually holds the main handle 70 with the right hand and holds the auxiliary handle 71 with the left hand to perform cutting operations.

[0083] The chainsaw of this embodiment has a main handle 70 disposed between the battery pack 40 and the cutting assembly 210, and has a compact structure suitable for use in tree operations. In some scenarios, the chainsaw of this embodiment is used by arborists who need to work on trees to prune, remove branches, etc.

[0084] For example, in some scenarios, a user needs to climb a tree to perform pruning or delimbing operations. While climbing the tree, the user connects the safety rope to the first hanging ring 50. Using the safety rope, the user and the chainsaw move synchronously to the target location. Alternatively, the user can connect the second hanging ring 60 to a self-locking hook worn by the user and carry the chainsaw to the target location. Upon reaching the target location, the user can single-handedly remove the self-locking hook from the second hanging ring 60 and hold the main handle 70 to operate the cutting assembly 210 relative to the front end. After cutting, the user can single-handedly connect the second hanging ring 60 to the self-locking hook worn by the user and carry the chainsaw to another location. Furthermore, the first hanging ring 50 and the second hanging ring 60 at the rear end are located in different regions in the width direction and at different heights in the height direction, so the safety rope and the self-locking hook will not become entangled at the rear end, thereby improving the convenience and safety of the operation.

[0085] It should be noted that, under the premise that there is no conflict, the power tools of the aforementioned embodiments can all be combined into the chain saw of this embodiment, so the aforementioned features will not be repeated in this embodiment.
