[0032] like Figures 1-4 As shown, an embodiment of this application proposes a handheld power tool accessory, including a first accessory 1 and a second accessory 2. The first accessory 1 is provided with a first limiting component 3, and the second accessory 2 is provided with a second limiting component 4. The first limiting component 3 and the second limiting component 4 cooperate to limit the relative position of the first accessory 1 and the second accessory 2 in a first direction X.

[0033] In some embodiments, both the first attachment 1 and the second attachment 2 are provided with at least one adjustment hole 5 for installing screws. The length direction of the adjustment hole 5 is consistent with the first direction X, and the installation position of the screw in the first direction X is adjusted within the adjustment hole 5.

[0034] In some embodiments, the relative distance between the first accessory 1 and the second accessory 2 in the second direction Z is adjustable. The distance between the adjustment hole 5 on the first accessory 1 and the adjustment hole 5 on the second accessory 2 is adjusted by adjusting the relative distance between the first accessory 1 and the second accessory 2. The first direction X is perpendicular to the second direction Z.

[0035] It should be noted that the handheld power tool accessories provided in this application embodiment can be external accessories, striking accessories, or a combination of external accessories and striking accessories.

[0036] When installing the handheld power tool accessories, the relative distance between the first accessory 1 and the second accessory 2 is manually adjusted, thereby changing the relative position between the adjustment holes 5. The installation position of the screw in the first direction X is adjusted within the adjustment hole 5. At this time, the installation position of the screw is determined. During the adjustment process, the first limiting component 3 and the second limiting component 4 limit the first accessory 1 and the second accessory 2 in the first direction X to prevent the first accessory 1 and the second accessory 2 from sliding relative to each other in the first direction X.

[0037] In some embodiments, during the process of adjusting the relative positions of the first accessory 1 and the second accessory 2, the first limiting component 3 and the second limiting component 4 also have a guiding function for the first accessory 1 and the second accessory 2; when used as a striking accessory, the first limiting component 3 and the second limiting component 4 serve as striking parts for the user to strike objects.

[0038] Since the screw's mounting position can be adjusted in both the first direction X and the second direction Z, the handheld power tool accessory provided in this embodiment has the technical advantage of wide applicability and compatibility with most power tool tail sizes.

[0039] In some embodiments, the first limiting component 3 includes two first limiting strips 31 extending to a first side of the second accessory 2; the second limiting component 4 includes a second limiting strip 41 extending to a second side of the first accessory 1, the second side being on the same side as the first side; the first limiting strips 31 and 41 are alternately distributed in a first direction X. Using the first limiting strips 31 and 41 to strike the object reduces not only the stress on the first accessory 1 and the second accessory 2, but also the vibration and deformation of the first accessory 1 and the second accessory 2 during the striking process.

[0040] In some embodiments, the first limiting strip 31 includes a first curved portion 311 and a first straight portion 312. One end of the first curved portion 311 is connected to the first accessory 1, and the other end is connected to the first straight portion 312. The second limiting strip 41 includes a second curved portion 411 and a second straight portion 412. One end of the second curved portion 411 is connected to the second accessory 2, and the other end is connected to the second straight portion 412. The first curved portion 311 facilitates the first limiting strip 31 extending into the first side of the second accessory 2, and the second curved portion 411 facilitates the second limiting strip 41 extending into the second side of the first accessory 1.

[0041] In some embodiments, the thickness of both the first accessory 1 and the second accessory 2 is d, and the vertical height of both the first limiting strip 31 and the second limiting strip 41 is D, where D-2d=±0.5mm. This restricts the size of the first accessory 1 and the second accessory 2, as well as the first limiting strip 31 and the second limiting strip 41, in order to enhance the tightness of the fit between the first limiting strip 31 and the second limiting strip 41 and improve the limiting effect on the first accessory 1 and the second accessory 2 in the first direction X. This prevents the first limiting strip 31 and the second limiting strip 41 from failing to firmly limit the first accessory 1 and the second accessory 2 together due to unsuitable size. In addition, since they are of the same size, it is more convenient to replace the parts.

[0042] In some embodiments, the first attachment 1 and the second attachment 2 each have two adjustment holes 5, and the center lines of the four adjustment holes 5 are connected end to end to form a rectangle. The adjustment holes 5 are oblong holes, which facilitate the adjustment of the screw installation position in the first direction X.

[0043] It should be noted that the shape of the adjusting hole 5 can be any shape that allows the screw installation position to be adjusted in the first direction X, including but not limited to oblong holes and oval holes. The screw in the oblong hole can be adjusted in the first direction X (moving within the oblong hole). Combined with the aforementioned screw installation position being adjustable in the second direction Z, the screw installation position can ultimately be adjusted in both the first direction X and the second direction Z.

[0044] In some embodiments, both the first attachment 1 and the second attachment 2 are made of metal. The handheld power tool attachment can be used as a hammering attachment, for example, it can replace a hammer or other tools when hammering nails, achieving multiple uses and making it more convenient for workers to use.

[0045] In some embodiments, the first accessory 1 is provided with a first pressure plate 8 corresponding to the second limiting strip 41, and the first pressure plate 8 is located on the side of the second limiting strip 41 facing away from the second side; the second accessory 2 is provided with a second pressure plate 9 corresponding to the first limiting strip 31, and the second pressure plate 9 is located on the side of the first limiting strip 31 facing away from the first side.

[0046] It should be noted that the second pressure plate 9 is part of the second accessory 2.

[0047] In some embodiments, when used as a striking accessory, the first limiting strip 31 and the second limiting strip 32 act as striking parts to strike an object. In order to reduce the deformation of the first limiting strip 31 and the second limiting strip 41 when striking the object, the first pressure plate 8 and the second pressure plate 9 respectively support the first limiting strip 31 and the second limiting strip 41, thereby reducing the problem of deformation of the first limiting strip 31 and the second limiting strip 41.

[0048] Working principle of this embodiment: When using this handheld power tool accessory, the first limiting strip 31 extends into the first side of the second accessory 2, and the second limiting strip 41 extends into the second side of the first accessory 1. Depending on the screw installation position, the extension stroke of the first limiting strip 31 and the second limiting strip 41 can be manually adjusted. The extension stroke determines the installation position of the screw in the second direction Z. After determining the installation position of the screw in the second direction Z, the screw to be installed is placed into the oblong hole, and then the installation position of the screw in the first direction X is adjusted in the oblong hole. After determining the installation position in the first direction X, the screw is tightened. In this way, the position of the screw in the first direction X and the second direction Z can be adjusted, so that this handheld power tool accessory can be used with most power tool tail sizes. Example 2

[0049] This embodiment proposes a handheld power tool accessory. Unlike the first embodiment, the handheld power tool accessory provided in this application, when used as an external accessory or an accessory that combines external attachment and hammering, has a stand plate 6 on the second accessory 2. The stand plate 6 has an external attachment 7, on which any item, such as a screwdriver bit, electric drill, flashlight, lithium battery, walkie-talkie, etc., can be quickly hung and used, which is very convenient.

[0050] This application also proposes a power tool including a handheld power tool attachment of any of the above-described technical solutions, wherein the handheld power tool attachment is detachably mounted on the tail cap of the power tool. Therefore, this power tool encompasses all the technical effects of the aforementioned handheld power tool attachments, and will not be repeated here.
