[0002] Current electric tools often require a stand to place and support the electric tools and the materials being processed when in use.

[0003] However, the current problem is that different power tools need to be matched with brackets corresponding to the power tools. This results in a certain power tool only being able to use a certain bracket. When it is necessary to switch to another power tool, another bracket needs to be replaced. This results in a waste of accessories and inconvenience for users.

[0004] For example, the current miter saw has a stand specifically adapted thereto. If the user does not use a miter saw and wants to place a dry cutter or a split grinder on the stand of the miter saw, it cannot be used because the installation size of the dry cutter or the split grinder is much larger than that of the miter saw. In particular, for power tools that cannot rotate the worktable, when mitering on the stand, the material being processed cannot be placed and supported as necessary. Utility Model Content

[0035] The adapter device for the electric tool described in the present invention will be further explained and illustrated below in conjunction with the drawings and specific embodiments of the specification. However, such explanation and illustration do not constitute an improper limitation on the technical solution of the present invention.

[0036] Current electric tools often require a stand to place and support the electric tools and the materials being processed when in use.

[0037] However, for different power tools, it is often necessary to match the corresponding brackets of the power tools. For example, for a miter saw, it has a matching miter saw bracket. When the miter saw is placed on the miter saw bracket, it can cut the material at an angle based on the miter cutting function of the miter saw itself.

[0038] However, if a dry cutter (GCD) or a split grinder (GCO) is placed on the miter saw stand, since the dry cutter (GCD) and the split grinder (GCO) themselves cannot rotate the worktable, the material being processed cannot be placed and supported as required when mitering is performed on the stand.

[0039] In view of the above technical problem, the utility model provides an adapter device for an electric tool in one embodiment.

[0040] Figure 1 The figure shows a state in which the electric tool is arranged on a bracket by the adapter device described in the utility model in one embodiment.

[0041] like Figure 1 As shown, the adapter is arranged between the power tool 1 and the bracket 2. Figure 1 From the perspective of the power tool, the adapter is installed at the bottom of the power tool and is therefore blocked by the power tool and cannot be seen. Figure 1 In the workstation shown, an electric tool, such as a dry cutter, can perform 0-angle cutting (or vertical cutting) on ​​the long material 3, and the cutting direction is consistent with the width direction of the material 3. At this time, the length direction of the cut material 3 is consistent with the length direction of the bracket 2, so when cutting, the processed material 3 can be placed in a stable position and supported stably, ensuring the smooth progress of the cutting process.

[0042] Figure 2 The figure shows another state in which the electric tool is arranged on the bracket by the adapter device described in the utility model in one embodiment.

[0043] like Figure 2As shown, in this workstation, an electric tool, such as a dry cutter, can cut the long material 3 obliquely, and the cutting direction has a certain angle with the width direction of the material 3. If the adapter device described in the utility model is not provided, there will be a certain angle between the length direction of the material 3 and the length direction of the bracket 2, and the material 3 is equivalent to extending from the side of the bracket 2, that is, the bracket 2 cannot provide a stable support for the material 3.

[0044] In the case of adopting the adapter device described in the utility model, if Figure 2 As shown, the power tool 1 is rotated at a certain angle relative to the bracket 2, so that the length direction of the processed material 3 is still consistent with the length direction of the bracket 2, so that during oblique cutting, the processed material 3 can still be firmly placed and firmly supported.

[0045] Figure 3 A schematic structural diagram of the adapter device described in the utility model in one embodiment is shown.

[0046] Figure 4 A schematic structural diagram of the adapter device of the present invention in one embodiment is shown from another perspective.

[0047] Figure 5 A side view of the adapter device of the present invention in one embodiment is shown.

[0048] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the adapter device may include: a first connecting member 4 configured as a plate-like structure, which is used to connect to the power tool 1; and a second connecting member 5 also configured as a plate-like structure, which is used to connect to the bracket 2.

[0049] The second connecting member 5 is rotatably connected to the first connecting member 4 via the rotating shaft 6, so that the installation angle of the electric tool relative to the bracket can be adjusted by adjusting the angle between the second connecting member 5 and the first connecting member 4. Once the angle is determined, the angle between the second connecting member and the first connecting member, that is, the relative position between the two, can be fixed by the fastening element 7.

[0050] In some more specific embodiments, Figure 3 As shown, the rotating shaft 6 can be configured as a bolt passing through the first connecting member 4 and the second connecting member 5, and the fastening element 7 is configured as a nut threadedly connected to the bolt. Once the angle between the first connecting member 4 and the second connecting member 5 is determined, the angle between the second connecting member and the first connecting member can be fixed by tightening the nut.

[0051] In some other embodiments, other methods may be used to fix the angle between the first connecting member 4 and the second connecting member 5. For example, a locking pin is provided on one of the first connecting member 4 and the second connecting member 5, and a plurality of circumferentially arranged locking grooves adapted to the locking pin are provided on the other one. When the locking pin falls into different locking grooves, it corresponds to different angles between the first connecting member 4 and the second connecting member.

[0052] Figure 6 The diagram shows a state in which the angle between the first connecting member and the second connecting member of the adapter device described in the utility model is 0 degrees in one embodiment.

[0053] like Figure 4 and Figure 6 As shown, in some more specific embodiments, the second connecting member 5 is provided with an arc groove 51, and the first connecting member 4 is provided with a pin 41, and the pin 41 is correspondingly arranged in the arc groove 51. When the second connecting member 5 rotates relative to the first connecting member 4, the length of the arc groove 51 limits the maximum value of the rotation angle. Therefore, those skilled in the art can limit the adjustment range of the adjustable angle between the first connecting member and the second connecting member by designing the length of the arc groove.

[0054] Of course, in some other embodiments, an arc groove may be provided on the first connecting member 4, and a pin may be provided on the second connecting member 5. Figure 4 and Figure 6 The arrangement shown is not in this way in order to further avoid interference with the power tool base that may occur when the pin is arranged on the second connecting member.

[0055] In the present invention, the connection between the first connecting member 4 and the electric tool can be implemented in various forms based on the structure of the electric tool.

[0056] For example, in some embodiments, Figure 3 As shown, the edge of the first connecting member 4 may be provided with a first connecting hole 42 for connecting to the electric tool.

[0057] In addition, in some embodiments, the first connecting member is further provided with a positioning pin 43 extending toward the electric tool. The positioning pin 43 is correspondingly inserted into a positioning hole provided at the bottom of the electric tool to realize rapid positioning of the first connecting member 4 and the electric tool.

[0058] Similarly, the connection between the second connecting member 5 and the bracket can also be implemented in various forms. For example, in some embodiments, Figure 4 and Figure 6 As shown, the edge of the second connecting member 5 may be provided with a second connecting hole 52 for connecting with the bracket.

[0059] Furthermore, in some embodiments, in order to further save materials or reduce the weight of the adapter, a hollow portion 44 may be provided on the first connecting member 4. Similarly, a hollow portion may also be provided on the second connecting member 5.

[0060] In this way, when the first connecting member 4 and the second connecting member are in Figure 6 In the relative position state shown, the angle between the first connecting member and the second connecting member is 0 degrees. At this time, the electric tool 1 is in the position on the bracket 2 as shown in FIG. Figure 7 The vertical cutting station shown in FIG. Figure 1 As shown, the length direction of the material 3 to be cut is consistent with the length direction of the bracket 2, so when cutting, the material 3 to be processed can be placed in a stable position and supported stably, ensuring the smooth progress of the cutting process.

[0061] exist Figure 6 In the state shown, the first connecting member 4 is rotated counterclockwise relative to the second connecting member 5 by a certain angle, such as 45° or 30°, so that a certain angle is formed between the first connecting member 4 and the second connecting member 5. At this time, the electric tool 1 is in the position on the bracket 2 as shown in FIG. Figure 8 At this time, due to the adjustment of the installation angle of the electric tool 1 relative to the bracket 2, the oblique cutting position is Figure 2 As shown, the length direction of the processed material 3 is still consistent with the length direction of the bracket 2, so when cutting obliquely, the processed material 3 can still be stably placed and stably supported.

[0062] Fig. 9 A three-dimensional structural schematic diagram of the adapter device described in the utility model in another embodiment is shown.

[0063] Fig.10 A side view of the adapter device of the present invention in another embodiment is shown.

[0064] Fig.11 A top view of the adapter device of the present invention in another embodiment is shown.

[0065] like Fig. 9 , Fig.10 and Fig.11 As shown, in this embodiment, the second connecting member 5 is also connected to the first connecting member 4 so as to be relatively rotatable via the rotating shaft 6, so that the installation angle of the electric tool 1 relative to the bracket 2 can be adjusted by adjusting the angle between the second connecting member 5 and the first connecting member 4. Once the angle is determined, the angle between the second connecting member and the first connecting member, that is, the relative position between the two, can be fixed by a fastening element.

[0066] and Figure 3 The embodiment shown is different in that Fig.10 As shown, in this embodiment, the first connecting member 4 includes a first half body 411 and a second half body 412 connected to each other.

[0067] like Fig.11 As shown, one of the first half body 411 and the second half body 412 is provided with an elongated slot 414, and the other is provided with a sliding pin 415, which is arranged in the elongated slot 414 and can slide along the elongated slot 414. This arrangement can adjust the distance between the first half body 411 and the second half body 412 by adjusting the position of the sliding pin 415 in the elongated slot 414, so that the first connecting member can be adapted to various electric tools with different base widths, so that the adapting device has better adaptability.

[0068] In addition, in some embodiments, Fig.10 As shown, the first half 411 and the second half 412 of the first connecting member 4 both have wings 418 that gradually rise in height from the center to the edge. This arrangement can further avoid possible interference between the first connecting member and the second connecting member on the basis of realizing the basic functions of the utility model, increase the operating space, and thus improve the user's comfort.

[0069] Fig.12 A schematic structural diagram of the adapter device of the present invention in another embodiment is shown from a bottom perspective.

[0070] like Fig.12 As shown, in this embodiment, the second connecting member 5 may also be provided with an arc groove 51, and the first connecting member 4 is provided with a pin 41, which is correspondingly arranged in the arc groove 51. When the second connecting member 5 rotates relative to the first connecting member 4, the length of the arc groove 51 limits the maximum value of the rotation angle. Therefore, those skilled in the art can also limit the adjustment range of the adjustable angle between the first connecting member and the second connecting member by designing the length of the arc groove.

[0071] In some more specific embodiments, Fig. 9 , Fig.10 and Fig.11 As shown, the edge of the first connecting member 4 is provided with a clamping groove 416 adapted to the base of the power tool, and the base of the power tool has a corresponding component inserted in the clamping groove, so as to achieve a preliminary connection between the power tool and the first connecting member 4, and then tighten the fixing bolt 413 screwed on the wall of the clamping groove to achieve a fastened connection between the power tool and the first connecting member.

[0072] Of course, in other embodiments, the first connecting member 4 may also be connected to the electric tool in other ways.

[0073] Similarly, the connection between the second connecting member 5 and the bracket can also be realized in various forms. For example, in some embodiments, the edge of the second connecting member 5 can be provided with a connection hole for connecting with the bracket.

[0074] Furthermore, in some embodiments, in order to further save materials or reduce the weight of the adapter, a hollow portion may be provided on the first connecting member 4. Fig.12 As shown, the second connecting member 5 may also be provided with a hollow portion.

[0075] In this way, when the first connecting member 4 and the second connecting member are in Fig.12 In the relative position state shown in FIG. 1 , the angle between the first connecting member 4 and the second connecting member 5 is 0 degrees. At this time, the electric tool 1 is in the position on the bracket 2 as shown in FIG. Fig.13 The vertical cutting station shown in FIG. Figure 1 As shown, the length direction of the material 3 to be cut is consistent with the length direction of the bracket 2, so when cutting, the material 3 to be processed can be placed in a stable position and supported stably, ensuring the smooth progress of the cutting process.

[0076] exist Fig.12 In the state shown, the first connecting member 4 is rotated counterclockwise relative to the second connecting member 5 by a certain angle, such as 45°, 30° or 20°, so that a certain angle is formed between the first connecting member 4 and the second connecting member 5. At this time, the electric tool 1 is in the position on the bracket 2 as shown in FIG. Fig.14 At this time, due to the adjustment of the installation angle of the electric tool 1 relative to the bracket 2, the oblique cutting position is Figure 2 As shown, the length direction of the processed material 3 is still consistent with the length direction of the bracket 2, so when cutting obliquely, the processed material 3 can still be stably placed and stably supported.

[0077] In some more specific embodiments, the electric tool may be an electric screwdriver or an electric wrench, or other electric tools equipped with a tool head.

[0078] It should be noted that the terms "up", "down", "left", "right" and "counterclockwise" described in this article are for ease of understanding and are based on Figures 1 to 13 This is an exemplary description of the setting method and direction of the adapter device, which is not intended to limit the present invention.
