[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0028] The power tools involved in this application can be handheld power tools that use power batteries as a power source in various scenarios. Taking garden / outdoor tools as an example, they can be electric chainsaws, hedge trimmers, lawnmowers, etc. In the various embodiments and drawings of this application specification, electric chainsaws are used as an example to illustrate the technical solutions of this application, but this should not be regarded as a limitation on the types of power tools in this application.

[0029] An electric chainsaw is a woodworking power tool that uses a rotating chain blade for sawing. Safety and portability are core user concerns. In equipment maintenance or chain replacement scenarios, users frequently need to use specific tool accessories (such as socket wrenches) to disassemble the chainsaw casing, chain guide, or drive components. However, socket wrenches are usually stored separately from the electric chainsaw, making the power tool inconvenient to carry and prone to loss. The power tool of this application effectively solves the above problems. The following is a detailed description of the power tool of this application.

[0030] Reference Figure 1 The power tool in one embodiment of this application includes a housing 1, a motor, a transmission mechanism, a hand guard 2, and a receiving space 3.

[0031] Reference Figure 1 and Figure 2 The housing 1 may have a gripping part 11 and a battery connection part 12, and a support part 13 may be provided on the battery connection part 12; the motor may be housed inside the housing 1, and the transmission mechanism may be housed inside the housing 1 and connected to the output shaft of the motor; the hand guard 2 is connected to the housing 1 and has a support member 21 and a tool connector 22.

[0032] When the power tool is placed in a predetermined posture via the support member 21 and the support portion 13, the line connecting the support member 21 and the support portion 13 forms a reference placement line. Figure 1 (As shown by the dashed line in the middle), the predetermined posture here refers to the posture of the power tool when it is supported by the support part 13 and the support member 21 without the battery pack installed; the receiving space 3 is located between the hand guard plate 2 and the reference placement line, and the tool connector 22 is located in the receiving space 3 and is used to place the tool accessory 5.

[0033] In this embodiment, the hand guard 2 protects the operator's hands from injury by cutting debris as much as possible. The support member 21 cooperates with the support part 13, so that when the power tool is placed in a predetermined posture via the support member 21 and the support part 13, the line connecting the support member 21 and the support part 13 can form a reference placement line. Thus, a tool connector 22 connected to the hand guard 2 can be installed in the receiving space 3 located between the hand guard 2 and the reference placement line. The tool attachment 5 of the power tool can be placed on the tool connector 22 without affecting the placement of the power tool in the predetermined posture. This prevents the loss of the tool attachment 5 and meets the need for readily available tool attachments, reducing maintenance downtime. Therefore, when the power tool in this embodiment is an electric chainsaw, it can improve the efficiency of equipment maintenance or chain replacement. Furthermore, the tool connector 22 has no negative impact on the mechanical strength and safety protection capability of the hand guard 2, and also avoids the increase in tool size or weight imbalance caused by adding other structures.

[0034] Reference Figure 1 The handguard 2 and the grip portion 11 can be enclosed to form a gripping space 4, and the receiving space 3 can be located on the side of the handguard 2 away from the gripping space 4. In this embodiment, the handguard 2 can be straight, curved, or a combination of straight and curved shapes, or other shapes, as long as it can form a gripping space 4 with the grip portion 11. This application does not impose any specific limitations on this.

[0035] Combination Figure 3 The following description uses the handguard 2, which includes a first body segment 23 and a second body segment 24 that are bent relative to each other, as an example to illustrate the shape of the handguard 2. This is not a limitation on the shape of the handguard 2 in this embodiment. Specifically, the first body segment 23 can be connected to the battery connection part 12, and the second body segment 24 can be connected to the grip part 11. By setting the first body segment 23 and the second body segment 24, the size of the grip space 4 can be adapted to the operator's hand. It is understood that the connection position of the first body segment 23 and the second body segment 24 with the housing 1 can also be reasonably adjusted, as long as a grip space 4 is formed between them and the grip part 11. The first body segment 23 and the second body segment 24 can be connected to the housing 1 by setting connecting ears and mounting holes. In this embodiment, the specific connection method between them and the housing 1 is not limited.

[0036] The support member 21 is located at the bend joint between the first body segment 23 and the second body segment 24, and the receiving space 3 is located on the side of the first body segment 23 away from the gripping space 4. The position of the support member 21 can cooperate with the support part 13 to place the power tool in a predetermined posture, and can also provide some support and reinforcement to the bend joint of the hand guard 2, reducing the possibility of the hand guard 2 breaking or being damaged due to excessive force at the bend.

[0037] Reference Figure 3 The handguard baffle 2 may be provided with a reinforcing member 25 on its surface near the receiving space 3. In this embodiment, the reinforcing member 25 is a reinforcing rib, and the number of reinforcing ribs can be reasonably set according to specific circumstances. This embodiment does not impose specific limitations on this.

[0038] Reference Figure 3 The support member 21 may include at least two spaced-apart first support plates 211, and the power tool is supported by the side of the first support plates 211 away from the grip part 11. In this embodiment, the number of first support plates 211 is not specifically limited, and may be two, three, four or even more, which is not listed in this embodiment.

[0039] Reference Figure 3 In an optional embodiment, the support member 21 may further include a second support plate 212 connected to at least two first support plates 211. The second support plate 212 may be connected to the side of the at least two first support plates 211 away from the receiving space 3. When the power tool is placed in a predetermined posture, the first support plates 211, the second support plates 212, and the support portion 13 are jointly supported on the support plane. The cooperative arrangement of the first support plates 211 and the second support plates 212 can ensure the strength of the support member 21, thereby supporting the power tool in the predetermined posture.

[0040] Reference Figure 3 In one optional embodiment, the height of the first support plate 211 gradually decreases in the direction approaching the receiving space 3. Wherein, combined with Figure 3 In terms of coordinate axes, the height of the first support plate 211 in this embodiment refers to the distance of the first support plate 211 in the Z direction.

[0041] Reference Figure 1 and Figure 2Tool attachment 5 can be detachably installed within tool connector 22. Tool attachment 5 can be housed within housing space 3, or it can be operatively detached from housing space 3. That is, when the operator does not need to use tool attachment 5, it can be placed within tool connector 22. When the operator needs to perform equipment maintenance or chain replacement, tool attachment 5 can be readily accessed from tool connector 22, thereby ensuring the efficiency of maintenance or replacement. When tool attachment 5 is housed within housing space 3, its position does not affect the power tool's placement in a predetermined posture.

[0042] Reference Figure 2 and Figure 3 In one optional embodiment, when the tool attachment 5 is housed in the housing space 3, the vertical projection of the tool attachment 5 onto the handguard 2 can be located within the area of ​​the handguard 2's surface. By reasonably setting the area of ​​the handguard 2's surface, it can be ensured that the tool attachment 5 is housed within the housing space 3, and its detachment from the tool connector 22 due to external interference can be minimized. That is, in this embodiment, the width and length of the tool attachment 5 are both smaller than the width and length of the handguard 2. Specifically, in this embodiment, the tool attachment 5 is installed on the first body segment 23 of the handguard 2; therefore, in this embodiment, the width and length of the tool attachment 5 are both smaller than the width and length of the first body segment 23 of the handguard 2. It should be noted that, in conjunction with... Figure 3 In this embodiment, the width refers to the distance in the X direction and the length refers to the distance in the Y direction.

[0043] Reference Figure 3 and Figure 4 The tool connector 22 includes two latches arranged opposite each other. Each latch includes a body portion 221 fixedly connected to the plate of the hand guard 2, and a protrusion 222 located on the side of the body portion 221 away from the plate. A groove for engaging the tool accessory 5 is formed between the body portion 221 and the protrusion 222 of the two latches, and the protrusion 222 of the two latches is located on the side of the two body portions 221 that are close to each other. In this embodiment, the tool accessory 5 is interference-fitted with the two latches to improve the ease of assembly and disassembly of the tool accessory 5. During the use of the power tool, the protrusion 222 can prevent the tool accessory 5 from detaching from the tool connector 22 due to vibration.

[0044] Reference Figure 4 In an optional embodiment, the buckle may further include a reinforcing portion 223 fixedly connected to the body portion 221. The reinforcing portion 223 is located on the side of the two buckles facing away from each other, and the width of the reinforcing portion 223 gradually decreases in the direction away from the plate. The reinforcing portion 223 may be configured as a reinforcing plate. It should be noted that, in conjunction with... Figure 4In this embodiment, the width of the reinforcing part 223 refers to its distance in the X direction, as understood from the coordinate axes. By providing the reinforcing part 223, the strength of the buckle can be ensured, guaranteeing its fastening force to the tool accessory 5 and its own structural strength.

[0045] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
