[0001] This application belongs to the field of tool technology, specifically relating to an electric tool. Background Technology

[0002] Power tools are portable or handheld mechanical devices powered by electricity (batteries or external power sources) for tasks such as cutting, drilling, grinding, fastening, and polishing. They are widely used in construction, manufacturing, and household applications. Some power tools are powered by external battery packs. However, battery packs of different capacities vary in weight and size, and changing the battery pack can shift the overall center of gravity of the power tool, thus increasing the user's workload.

[0003] Therefore, it is necessary to provide an electric tool to address the aforementioned technical problems. Utility Model Content

[0004] The purpose of this application is to provide a power tool that can solve the problem mentioned above where changing the battery pack causes a change in the center of gravity of the power tool, thereby increasing the user's operational burden.

[0005] To achieve the above objectives, a specific embodiment of this application provides the following technical solution:

[0006] An electric tool includes a housing, a motor, and a transmission assembly connected to the output end of the motor; the electric tool further includes a socket for connecting a battery pack, the socket being slidably connected to the housing, the socket having a first position and a second position fixed relative to the housing in a sliding direction, and the socket being closer to the center of gravity of the electric tool in the first position than in the second position.

[0007] In one or more embodiments of this application, the first position is located in the direction in which the socket moves toward the center of gravity of the power tool in the second position.

[0008] In one or more embodiments of this application, the socket is moved along the length of the power tool.

[0009] In one or more embodiments of this application, the socket is provided with a limiting member, and the housing is provided with two limiting portions.

[0025] 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.

[0026] Reference Figure 1 The power tools in this application include, but are not limited to, electric drills, angle grinders, chainsaws, impact wrenches, lawn mowers, and other power tools. This embodiment and the accompanying drawings illustrate the power tools of this application using a lawn mower as an example, but this is not intended to limit their type.

[0027] Reference Figure 1 and Figure 2 One embodiment of the power tool in this application includes a housing 1, an extension rod 2 connecting the housing 1 and a motor, a motor, a transmission assembly connected to the output end of the motor, and a working head 3 mounted on the output end of the transmission assembly. In this embodiment, the working head 3 is illustrated by taking a grass trimmer as an example. When the power tool of this application is running, the extension rod 2 helps to adjust the position of the working head 3, and the motor drives the transmission assembly to run, so that the grass trimmer cuts weeds. It is understood that when the power tool is other types of tools, the working head 3 can also be a drill bit, saw blade, or other structures, and the extension rod 2 can also be omitted depending on the different power tools.

[0028] Reference Figure 1 and Figure 2Furthermore, the power tool in this embodiment also includes a socket 5 for connecting the battery pack 4. The socket 5 is slidably connected to the housing 1. The socket 5 has a first position and a second position that are relatively fixed to the housing 1 in the sliding direction, and the socket 5 is closer to the center of gravity of the power tool in the first position than in the second position. When the socket 5 is connected to the battery pack 4, it can provide power for the operation of the power tool.

[0029] Depending on different usage needs, the socket 5 can be used to fix battery packs 4 of different capacities. Therefore, in this application, when replacing battery packs 4 of different capacities, the socket 5 can be set in the first position or the second position to balance the center of gravity of the power tool, thereby adapting to the user's usage needs, reducing the user's burden, and optimizing the user experience.

[0030] For example, the battery pack 4 in this embodiment may include a 4Ah battery pack and an 8Ah battery pack, such as Figure 1 When using an 8Ah battery pack, socket 5 can be fixed in the first position; such as Figure 2 When using a 4Ah battery pack, socket 5 can be fixed to the second position to adjust the center of gravity of the whole machine, thereby optimizing the user experience.

[0031] In this embodiment, the first position is set in the direction in which the socket 5 moves toward the center of gravity of the power tool in the second position. The socket 5 moves along the length of the power tool. The direction of movement of the socket 5 and the setting of the first and second positions allow the user to adjust the position of the socket 5 according to the battery pack 4 being used, reducing the burden of use and adapting to their usage habits.

[0032] Reference Figure 3 and Figure 5 The socket 5, on the side away from the housing 1, is fixedly connected to a plug-in portion 51 for connecting the battery pack 4. The plug-in portion 51 can be fitted with a guide rail and a slot for guiding and locking the battery pack 4. This connection structure is conventional in the art and will not be described in detail here.

[0033] Reference Figure 3 and Figure 4 The socket 5 is provided with a limiting member 6, and the housing 1 is provided with two limiting parts 11. The limiting member 6 can be selectively engaged with one of the limiting parts 11 to restrict the socket 5 to a first position or a second position. In this embodiment, the housing 1 has two slots along the sliding direction of the socket 5, and the limiting part 11 is the slot wall of the slot. The limiting member 6 can be selectively inserted into the slot. When the limiting member 6 is inserted into different slots, the socket 5 can be restricted to either the first position or the second position accordingly.

[0034] In other embodiments, the limiting part 11 may not have a slot in the housing 1. Instead, two opposing snap-fit ​​baffles are provided in the housing 1, which engage with the limiting member 6 to restrict the socket 5 to different positions. Therefore, the specific form of the limiting part 11 is not specifically limited in this application.

[0035] Reference Figure 4 and Figure 5 The socket 5 has a mounting groove 52 for accommodating the limiting member 6. The limiting member 6 can move along the mounting groove 52 to selectively engage or disengage with the limiting part 11. In this embodiment, the extending direction of the mounting groove 52 is perpendicular to the extending direction of the socket 5, which is used to restrict the movement of the socket 5. When the limiting member 6 slides along the mounting groove 52 to different positions, it can engage or disengage with the limiting part 11, thereby adjusting the socket 5 to a first position or a second position.

[0036] Reference Figure 4 and Figure 5 Specifically, the limiting member 6 includes a body portion 61 and a push button portion 62 connected to one side of the body portion 61. The body portion 61 slides through the mounting groove 52 and can engage or disengage with the limiting member 11. The socket 5 has a through groove 53 for the push button portion 62 to extend through. Therefore, when the push button portion 62 is pushed to move, the body portion 61 can be driven to engage or disengage with the limiting member 11.

[0037] Reference Figure 4 and Figure 5 The power tool also includes an elastic element 7 installed at the bottom of the mounting groove 52. The elastic element 7 has an elastic force that drives the limiting element 6 to move to a position where it engages with the limiting part 11. Therefore, when the socket 5 moves to the first position or the second position, the elastic element 7 can drive the limiting element 6 to automatically move into the slot, thereby limiting the socket 5 to the corresponding position. In this embodiment, the elastic element 7 can be set as a spring to drive the limiting element 6 to move. When it is necessary to adjust the position of the socket 5, the push button 62 can be pushed away from the slot, and then the socket 5 can be slid to another position, so that the limiting element 6 engages with the limiting part 11 at the corresponding position.

[0038] Reference Figure 3 and Figure 5The socket 5 includes a body 54 and snap-fit ​​plates 55 connected to both sides of the body 54. One end of the snap-fit ​​plate 55 away from the body 54 is bent to form a guide portion. The housing 1 is provided with a guide groove 12 that mates with the guide portion. In this embodiment, the guide groove 12 is located inside the housing 1, and a clearance groove 13 is provided on the side of the housing 1 near the socket 5 to allow the snap-fit ​​plate 55 to pass through. Therefore, the socket 5 can slide along the length of the power tool. The cooperation between the guide portion and the guide groove 12 guides the movement of the socket 5 and supports the socket 5, preventing it from detaching from the housing 1. The guide groove 12 can be formed on the housing 1, or it can be formed by two opposing protrusions inside the housing 1, with the two protrusions engaging to form the guide groove 12. This application does not impose specific limitations on this. It is understood that in other embodiments, the guide groove 12 can also be located outside the housing 1, and this application does not impose specific limitations on this either.

[0039] 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.

[0040] 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. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
