DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The replacement tool head 100 in the embodiment of the present application refers to a tool head that can be installed on a handheld power tool (for example, an electric screwdriver, etc.). Figure 1 As shown, the replacement tool head 100 has a mounting end 120, and the mounting end 120 has a slot portion 121. The slot portion 121 is a section of the replacement tool head 100 where a slot is set. The slot portion 121 cooperates with a clamping fixture in a bit mounting seat of a handheld power tool, so that the replacement tool head 100 is installed in the bit mounting seat of the handheld power tool. The replacement tool head 100 can be provided with a slot portion 121 at one end, or at both ends. Exemplarily, the replacement tool head 100 can be a bit, a bit sleeve, or a bit extension rod, etc.

[0051] like Figure 2 , Figure 3 and Figure 4 As shown, the replacement tool head quick-hanging device provided in the embodiment of the present application includes a placement seat 200 and a back clip. The placement seat 200 includes a back plate 210 and a plurality of spacers 220. The plurality of spacers 220 are arranged at intervals along the first direction. The distance between two adjacent spacers 220 is greater than the diameter of the slot portion 121 and less than the diameter of the replacement tool head 100. In any spacer 220, the first end of the spacer 220 in the extension direction is connected to the back plate 210, and a placement space is formed between two adjacent spacers 220. In the extension direction of the spacer 220, the side of the placement space away from the first end of the spacer 220 is an opening. Any two adjacent spacers 220 are configured as openings for the slot portion 121 to be loaded into the placement space, and the two adjacent spacers 220 are partially extended into the slot portion 121.

[0052] In this embodiment, the back clip is installed on the side of the back plate 210 facing away from the spacer 220, and the back clip is configured to at least be able to be hung on the user, and when the back clip is hung on the user and the replacement tool head 100 is placed on the placement seat 200, the replacement tool head 100 is suspended on the placement seat 200. The back clip at least being able to be hung on the user means that the back clip can be hung on the user's belt, clothing and other wearable accessories. In addition, the back clip of the embodiment of the present application is not limited to being able to be hung on the user, and the user can also hang it in other locations when not in use, such as a wall hanging board, etc., to facilitate the storage of the replacement tool head quick hanging device.

[0053] The replacement tool head quick-hanging device provided in the embodiment of the present application can be hung on the user, which is convenient for the user to carry with him. The replacement tool head 100 can be loaded into the placement space from the opening of the placement space. That is to say, the user can load the commonly used replacement tool head 100 into the placement space from the opening of the placement space, forming two adjacent spacers 220 of the placement space, respectively partially extending into the slot portion 121, that is, the replacement tool head 100 parts on both sides of the slot portion 121 are respectively located on both sides of the spacer 220, and the two spacers 220 cooperate to clamp the replacement tool head 100 so that it is clamped between the two spacers 220. When the replacement tool head quick-hanging device is hung on the user and the replacement tool head 100 is placed on the placement seat 200, the replacement tool head 100 is hung on the placement seat 200. When the user is working on site, the replacement tool head 100 suspended on the placement seat 200 can be taken out from the opening of the placement space for use according to needs, and the unused replacement tool head 100 can be loaded into the placement space from the opening. The replacement tool head quick-hanging device provided in the embodiment of the present application is convenient for the user to carry around a replacement tool head 100, and is easy to operate.

[0054] It should be noted that the distance between two adjacent spacers 220 refers to the distance between the two adjacent spacers 220, that is, in two adjacent spacers 220, the distance between the side of the first spacer 220 facing the second spacer 220 and the side of the second spacer 220 facing the first spacer 220. In addition, the extension direction refers to the extension track direction of the long side of the spacer 220, such as Figure 4 In the figure, the extending direction of the spacer 220 is the track direction of the upper vertical part and the lower arc part.

[0055] In some embodiments of the present application, the replacement tool head quick-hanging device further includes a limit cover, which is rotatably connected to the back plate 210, and the limit cover is configured to open or cover the opening of each placement space. The opening of the placement space is normally in a closed state, that is, the limit cover covers the opening of each placement space. When it is necessary to take out or load the replacement tool head 100, the limit cover is rotated to open the opening of the placement space, and the replacement tool head 100 can be taken out or put in from the opening of the placement space. This setting ensures that no matter how the replacement tool head quick-hanging device is placed, the replacement tool head 100 will not fall out of the placement space.

[0056] like Figure 2 and Figure 6 As shown, in this embodiment, the limiting cover includes at least one cover body 300. For any cover body 300, the cover body 300 is rotatably connected to the back plate 210, and the cover body 300 opens or covers at least one opening of the placement space. That is, the limiting cover can include one cover body 300 or multiple cover bodies 300, for example, Figure 2 and Figure 3As shown, the number of the cover 300 is one, and the cover 300 opens or covers the openings of all the placement spaces. A plurality of covers 300 refers to two or more, for example, three covers 300, four covers 300, or five covers 300. For example, Figure 6 As shown, the number of the covers 300 is the same as the number of the placement spaces and corresponds one to one. In the corresponding covers 300 and placement spaces, the covers 300 open or cover the openings of the placement spaces.

[0057] In some embodiments of the present application, Figure 4 As shown, at least some of the spacers 220 are provided with ribs 230, and in the corresponding ribs 230 and spacers 220, the ribs 230 connect the spacers 220 and the back plate 210. The ribs 230 are used to strengthen the strength of the spacers 220. Exemplarily, all spacers 220 are provided with ribs 230, wherein the structures of the ribs 230 may be the same or different, which is not specifically limited here.

[0058] For example, in some embodiments of the present application, Figure 2 , Figure 3 and Figure 4 As shown, the number of the cover body 300 is one. At least each spacer 220 located in the middle is provided with a rib plate 230, and in at least the rib plate 230 corresponding to the spacer 220 located in the middle, the side of the rib plate 230 facing away from the first end of the spacer 220 is an arc structure 231. That is to say, in addition to the rib plate 230 corresponding to the spacer 220 located in the middle being provided with an arc structure 231, the rib plates 230 corresponding to the two spacers 220 located at both ends may also be provided with an arc structure 231. The cover body 300 has a third end and a fourth end opposite to each other, the third end of the cover body 300 is rotatably connected to the back plate 210, and the fourth end of the cover body 300 rotates along the arc structure 231. That is to say, the arc structure 231 plays a guiding role, guiding the fourth end of the cover body 300 to rotate along the arc structure 231.

[0059] It should be noted that the spacer sheets 220 located in the middle refer to all the spacer sheets 220 located between the two spacer plates at both ends.

[0060] Please continue reading Figure 2 , Figure 3 and Figure 4In some embodiments of the present application, the second end of at least one spacer 220 is a blocking edge 240, and the blocking edge 240 is configured to block the rotation of the cover 300, and the rotation position of the cover 300 is limited between the back plate 210 and the blocking edge 240. In other words, the cover 300 can only rotate between the back plate 210 and the blocking edge 240. When the cover 300 rotates to abut against the blocking edge 240, the cover 300 covers the opening of the placement space, and the cover 300 rotates toward the back plate 210 to open the opening of the placement space. Exemplarily, the ends of the second ends of all spacers 220 are flush, and the second ends of all spacers 220 are blocking edges 240 to block the rotation of the cover 300.

[0061] like Figure 2 and Figure 5 As shown, in some embodiments of the present application, the fourth end of the cover body 300 is bent toward the side where the rib plate 230 is located to form a bent edge 311, and the bent edge 311 is provided with a limiting groove 312 corresponding to the blocking edge 240. When the cover body 300 covers the openings of each placement space, the blocking edge 240 is located in the corresponding limiting groove 312, and when the cover body 300 rotates, the groove bottom of the limiting groove 312 rotates along the corresponding arc structure 231. In other words, the limiting groove 312 and the arc structure 231 cooperate to guide the rotation of the cover body 300, and the arc structure 231 extends into the limiting groove 312, so that the cover body 300 will not rotate left and right when rotating, thereby enhancing the stability of the rotation of the cover body 300 and reducing the shaking or deviation of the cover body 300 when rotating.

[0062] In some embodiments of the present application, the replacement head quick-hanging device further includes a reset member, which is configured to cause the limit cover to reset from the opening state of opening the placement space to the opening state of covering the placement space. That is, after the user presses the cover body 300 to open the opening of the placement space to take out or insert the replacement tool head 100, and releases the force pressing the cover body 300, the cover body 300 is reset to the opening position of the covering placement space under the action of the reset member.

[0063] Exemplarily, a mounting shaft is fixedly connected to the back plate 210. For any cover 300, one end of the cover 300 is rotatably sleeved on the mounting shaft. The reset member includes at least one torsion spring, and one cover 300 corresponds to at least one torsion spring. In the corresponding cover 300 and torsion spring, the first mounting portion of the torsion spring is connected to the back plate 210, and the second mounting portion of the torsion spring is connected to the cover 300.

[0064] Exemplarily, when there is one cover body 300, the cover body 300 may correspond to one torsion spring, or two torsion springs, or more torsion springs; when the number of cover bodies 300 is the same as the number of accommodating spaces, one cover body 300 may correspond to one torsion spring.

[0065] Exemplarily, the torsion spring can be a single torsion spring or a double torsion spring. Exemplarily, when the torsion spring is a single torsion spring, the two ends of the torsion spring are respectively a first mounting portion and a second mounting portion, and when the torsion spring is a double torsion spring, the middle section of the torsion spring is the first mounting portion, and the sections at the two ends of the torsion spring are the second mounting portions.

[0066] It should be noted that the first mounting portion of the torsion spring is connected to the back plate 210 , and the second mounting portion of the torsion spring is connected to the cover body 300 . The connection refers to abutment, fixed connection or plug-in connection.

[0067] In some embodiments of the present application, the back clip includes a belt clip, and the belt clip is configured to be hooked on a waist belt. In other words, the replacement tool head quick-hanging device can be hooked on the user's waist belt, and the user can carry it with him, so as to facilitate the use of the replacement tool head 100 during on-site construction (such as high-altitude work).

[0068] An embodiment of the present application also provides a handheld power tool kit, which includes a handheld power tool, a plurality of replacement tool heads 100, and a replacement tool head quick-hanging device of any of the above-mentioned schemes, and the plurality of replacement tool heads 100 are installed on the replacement tool head quick-hanging device.
