[0002] In the field of electric tools, most products are equipped with a series of auxiliary tool accessories, such as an inner hexagonal wrench for a circular saw, an open-end wrench for a slotting machine, a fastening wrench for an angle grinder, and a special screwdriver for a chain saw, which are designed to assist end users to perform basic installation and maintenance work.

[0003] In the current market, some manufacturers tend to directly place these accessories in the packaging box for users to properly store and retrieve for use when needed. However, this practice often leads to the loss of accessories due to user negligence, thereby affecting the convenience of use. Therefore, the accessories can be integrated into a special storage structure inside or near the tool body to achieve integrated management with the host machine. Users can instantly access and easily return to the preset installation slot after use, greatly improving user experience and operational efficiency.

[0004] The existing storage structure is generally of two types: one type of storage structure is a receiving groove provided on the surface of the housing, and the auxiliary tool accessories are placed in the receiving groove. However, this storage structure has an excessively large opening, which not only increases the contact area between the auxiliary tool accessories and external objects, thereby increasing the risk of accidental falling of the auxiliary tool accessories, but also adversely affects the overall aesthetic appearance of the electric tool. The other type of storage structure improves the stability of the connection between the auxiliary tool accessories and the housing through a complex structure. The storage structure has a clamping piece clamping the accessory tool and a fixing assembly fixing the shaft sleeve part outside the housing of the electric tool, but the result is excessively complex, and the process of taking and placing the accessory tool is relatively cumbersome and inconvenient.

DETAILED DESCRIPTION

[0030] In order to make the person skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0031] As shown in FIGS. Figure 1 , 2 and 4, the electric tool in an embodiment of the present application comprises a housing 1, and a motor, a battery assembly, a transmission assembly and an output 2 mounted on the housing 1; the motor is electrically connected with the battery assembly, the output 2 is connected with the motor through the transmission assembly, the outer surface of the housing 1 is provided with a containing hole 11 for mounting an auxiliary tool accessory 3, and a limiting portion 12 is protruded on the inner wall of the containing hole 11; the auxiliary tool accessory 3 comprises a long handle end 31, in a first state, the long handle end 31 of the auxiliary tool accessory 3 is inserted in the containing hole 11, and the limiting portion 12 and the auxiliary tool accessory 3 are clamped with each other.

[0032] It can be understood that, in the first state, the long handle end 31 of the auxiliary tool accessory 3 is inserted in the containing hole 11, and the insertion direction is the axial direction of the containing hole 11, so as to reduce the contact area of the auxiliary tool accessory 3 with the outside world. The limiting portion 12 provided on the inner wall of the containing hole 11 and the auxiliary tool accessory 3 are clamped with each other, so as to realize the effect of stably containing the auxiliary tool accessory 3 in the containing hole 11. Since the process of mounting the auxiliary tool accessory 3 in the containing hole 11 only needs a simple insertion process, and the auxiliary tool accessory 3 inserted in the containing hole 11 and the limiting portion 12 are clamped with each other, the convenience and rapidity of taking and placing the auxiliary tool accessory 3 are realized.

[0033] As shown in FIGS. Figure 4 In the present embodiment, the auxiliary tool accessory 3 comprises a long handle end 31 and a short handle end 32. In order to better introduce the electric tool of the present application, the electric tool is taken as a chain saw, and the auxiliary tool accessory 3 is taken as a hex socket wrench to illustrate the electric tool of the present application. The axial end of the long handle end 31 is connected with the outer periphery of the short handle end 32, and it can be considered that the long handle end 31 and the short handle end 32 are arranged in a T shape. The long handle end 31 can comprise a screwdriver end head 311, and the short handle end 32 comprises a hexagonal hole 321 and a round hole 322.

[0034] The first state can be considered as the state in which the auxiliary tool accessory 3 is securely received in the receiving hole 11. In this state, the auxiliary tool accessory 3 can be completely received in the receiving hole 11, that is, both the long handle end 31 and the short handle end 32 of the auxiliary tool accessory 3 are located in the receiving hole 11; the auxiliary tool accessory 3 can also be partially received in the receiving hole 11, that is, the long handle end 31 is received in the receiving hole 11, and the short handle end 32 is partially received in the receiving hole 11.

[0035] like Figure 3 As shown, in this embodiment, the receiving hole 11 includes an embedding groove 111 provided on the surface of the housing 1, and an embedding hole 112 provided at the bottom of the embedding groove 111. The extension direction of the embedding hole 112 forms an angle with the length direction of the embedding groove 111. In this embodiment of the present application, the extension direction of the embedding hole 112 and the length direction of the embedding groove 111 are perpendicular to each other. The auxiliary tool accessory 3 includes a short handle end 32. In the first state, the long handle end 31 of the auxiliary tool accessory 3 is inserted into the embedding hole 112, and the short handle end 32 of the auxiliary tool accessory 3 is inserted into the embedding groove 111. Part of the short handle end 32 of the auxiliary tool accessory 3 is loosely fitted with the inner wall of the embedding groove 111. This design allows the short handle end 32 to be closer to or located at the opening of the receiving hole 11, while the long handle end 31 is located inside the receiving hole 11, avoiding the hidden danger of the screwdriver tip 311 of the long handle end 31 facing the opening of the receiving hole 11. In addition, when the user needs to remove the auxiliary tool accessory 3 from the housing 1 , the short handle end 32 is more convenient for the user to hold and apply force, thereby facilitating the removal of the auxiliary tool accessory 3 .

[0036] Preferably, the housing 1 has a battery compartment 13 for accommodating the battery assembly, and the embedding hole 112 is provided between the outer wall of the battery compartment 13 and the inner wall of the housing 1. Figure 2 As shown, the battery compartment 13 is formed on the outer surface of the left side of the shell 1, and the battery assembly can be detachably inserted into the battery compartment 13; in the left and right directions of the shell 1, the embedding hole 112 is located between the outer wall of the battery compartment 13 (that is, the right side wall of the battery compartment 13) and the inner wall of the shell 1 (that is, the right side wall of the shell 1). Such a design can utilize the restricted space between the outer wall of the battery compartment 13 and the inner side of the shell 1 without increasing the space inside the shell 1 or introducing components, thereby realizing the function of accommodating the auxiliary tool accessory 3 and significantly reducing the space occupied by the surface of the shell 1.

[0037] Furthermore, the embedding groove 111 is provided on one side of the bottom surface of the housing 1. During the use of the power tool, the bottom of the housing 1 is less likely to touch external objects and the user himself, which can further prevent the risk of the auxiliary tool accidentally falling out of the receiving slot due to accidental touch.

[0038] The insertion slot 111 includes a receiving area 1111 and at least one escape area provided on the side of the receiving area 1111. In a first state, the receiving area 1111 accommodates the short handle 32 of the auxiliary tool accessory 3. The escape area facilitates the user's hand or other tool to be inserted into the escape area, thereby grasping or clamping the short handle 32 and removing the auxiliary tool accessory 3.

[0039] like Figure 3 As shown, in this embodiment, the avoidance area includes a first avoidance area 1112 and a second avoidance area 1113 that are relatively arranged along the length direction of the short handle end 32, and the end portion of the short handle end 32 in the length direction is opened and communicated with the avoidance area. Herein, the length direction of the short handle end 32 can also be considered as the length direction of the embedding groove 111 or the axial direction of the short handle end 32. The end portion of the short handle end 32 in the length direction is opened and communicated with the avoidance area so that the user's fingers can extend from the first avoidance area 1112 and the second avoidance area 1113 into the hexagonal hole 321 and the circular hole 322 respectively. That is, when the user needs to take out the auxiliary tool accessory 3, the user's fingers can extend from the first avoidance area 1112 and the second avoidance area 1113 into the hexagonal hole 321 and the circular hole 322 respectively, thereby improving the stability of the user holding the auxiliary tool accessory 3 and making it easier for the user to apply force to take out the auxiliary tool accessory 3. As shown Figure 2 As shown, the limiting portion 12 is provided on the inner wall of the insertion groove 111 and has an abutting surface 121 facing the insertion hole 112. In the first state, the abutting surface 121 abuts against the auxiliary tool accessory 3. That is, the limiting portion 12 abuts against the auxiliary tool accessory 3 via the abutting surface 121, thereby locking the limiting portion 12 and the auxiliary tool accessory 3, thereby restricting the auxiliary tool accessory 3 from being removed from the receiving hole 11.

[0040] Furthermore, in the first state, the auxiliary tool accessory 3 is clamped between the abutment surface 121 and the inner wall of the insertion groove 111. That is, the auxiliary tool accessory 3 is clamped by the abutment surface 121 and the inner wall of the insertion groove 111, thereby firmly confining (accommodating) the auxiliary tool accessory 3 in the accommodating groove.

[0041] like Figure 2 As shown, in this embodiment, the abutting surface 121 of the limiting portion 12 abuts against the outer peripheral surface of the short handle end 32 facing away from the long handle end 31 , thereby achieving the locking of the limiting portion 12 and the auxiliary tool accessory 3 .

[0042] like Figure 5As shown, in another embodiment, in the first state, part of the limiting portion 12 can protrude into the hexagonal hole 321 or the circular hole 322, and the abutting surface 121 of the limiting portion 12 abuts against the inner wall of the hexagonal hole 321 or the circular hole 322, that is, the limiting portion 12 cooperates with the inner wall of the embedded groove 111 to clamp the auxiliary tool accessory 3, thereby firmly limiting (accommodating) the auxiliary tool accessory 3 in the accommodating groove.

[0043] Preferably, the limiting portion 12 is an elastic limiting portion 12 , for example, the limiting portion 12 may be made of rubber or other elastic materials.

[0044] In this embodiment, the material of the limiting portion 12 can be consistent with that of the shell 1, such as plastic material, which is convenient for one-piece molding. Since the deformation of the plastic material is smaller than that of the rubber material, when other features are consistent, the protrusion height or size of the limiting portion 12 made of plastic material in the accommodating hole 11 is smaller than the protrusion height or size of the limiting portion 12 made of rubber material in the accommodating hole 11.

[0045] like Figure 2 As shown, the limiting portion 12 has a guide surface 122 disposed away from the embedding hole 112. The guide surface 122 can facilitate the insertion of the auxiliary tool accessory 3 into the receiving hole 11.

[0046] Preferably, the abutting surface 121 is an inclined surface or an arc surface. Such a configuration can facilitate the user to remove the auxiliary tool accessory 3 from the receiving hole 11.

[0047] It can be understood that, no matter which embodiment is used, the auxiliary tool accessory 3 can be a part of the power tool, or an accessory outside the power tool (ie, not a part of the power tool).

[0048] In summary, the beneficial effects of the electric tool of the present application are:

[0049] (1) Auxiliary tool accessories are accommodated on the housing without increasing the space inside the housing or introducing any components.

[0050] (2) The auxiliary tool accessory is inserted into the housing along the axial direction of the long handle end, which reduces the contact area between the auxiliary tool accessory and the outside world, which not only reduces the risk of accidental falling of the auxiliary tool accessory, but also significantly enhances the safety performance of the power tool.

[0051] (3) The process of taking and placing the auxiliary tool accessories on the shell is simplified, making the process more convenient and more in line with the user's daily tool holding habits, significantly improving the user's comfort and efficiency.

[0052] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics thereof. The presently disclosed embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
