[0026] As known from the background, the practicability of the auxiliary handle in the related art needs to be improved.

[0027] In the technical scheme of the auxiliary handle provided in the embodiments of the present disclosure, the auxiliary handle comprises: a handle body; a clamping hoop connected with the handle body, the clamping hoop being used for being sleeved on the electric tool to connect the handle body and the electric tool; a mounting portion, the mounting portion being configured as a part of the clamping hoop, the mounting portion connecting the clamping hoop and the handle body; and a locking assembly, the locking assembly being used for adjusting the tension of the clamping hoop and positioning the clamping hoop at multiple positions of the electric tool; wherein the mounting portion and the locking assembly are angularly arranged on the circumferential surface of the clamping hoop, or the projections of the mounting portion and the locking assembly on the axial end surface of the handle body at least partially overlap. Compared with the scheme in the related art in which a screw needs to be rotated to realize the separation of the handle body and the electric tool, in the auxiliary handle provided in the embodiments of the present disclosure, a user can directly adjust the tension of the clamping hoop through the locking assembly to realize the separation or installation of the handle body and the electric tool, so that the time for separating or installing the handle body and the electric tool can be shorter, the quick disassembly and assembly of the handle body and the electric tool can be realized, and thus the practicability of the auxiliary handle can be improved.

[0028] The embodiments of the present disclosure will be described in detail below with reference to the drawings. However, those skilled in the art can understand that, in the embodiments of the present disclosure, many technical details are proposed in order to enable the readers to better understand the present disclosure. However, the technical scheme claimed by the present disclosure can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0029] Figure 1 FIG. 1 is a structural schematic diagram of an auxiliary handle provided for some embodiments of the present disclosure, Figure 2 FIG. 2 is an exploded schematic diagram of the auxiliary handle provided for some embodiments of the present disclosure.

[0030] Combined with reference Figure 1 and Figure 2 The auxiliary handle 100 is applied to an electric tool (not shown), which can be an angle grinder, a power drill, an electric hammer, etc., and here is preferably an angle grinder. The auxiliary handle 100 comprises: a handle body 101, a clamping hoop 102, a mounting portion (not identified), and a locking assembly. The clamping hoop 102 is connected with the handle body 101, the clamping hoop 102 is used for being sleeved on the electric tool to connect the handle body 101 and the electric tool; the mounting portion is configured as a part of the clamping hoop 102, the mounting portion connects the clamping hoop 102 and the handle body 101; and the locking assembly is used for adjusting the tension of the clamping hoop 102 and positioning the clamping hoop 102 at multiple positions of the electric tool; wherein the mounting portion and the locking assembly are angularly arranged on the circumferential surface of the clamping hoop 102.

[0031] The clamping hoop 102 comprises a main body 112, a locking assembly in the form of a folding buckle mechanism 122 connected to the main body 112, and a mounting portion in the form of a bottom plate connected to the handle body 101 on the main body 112. An included angle between the mounting portion and the folding buckle mechanism 122 is less than 180 degrees. The folding buckle mechanism 122 is provided with a buckle. The main body 112 is provided with a buckle slot 132 for connecting the buckle. The radial size of the clamping hoop 102 is adjusted by connecting or moving away the buckle from the buckle slot 132, so as to mount or separate the handle body 101 from the power tool.

[0032] The handle body 101 is used for a user to hold.

[0033] The clamping hoop 102 is used for sleeving on the power tool, so as to connect the handle body 101 with the power tool. Specifically, the user can open the folding buckle mechanism 122, move the buckle away from the buckle slot 132, make the radial size of the clamping hoop 102 larger, and make the clamping hoop 102 looser, so that the user can sleeve the clamping hoop 102 on the power tool. Then, the buckle is buckled with the buckle slot 132, the buckle is connected in the buckle slot 132, the radial size of the clamping hoop 102 is made smaller, and the clamping hoop 102 is made tighter, so as to fixedly connect the handle body 101 with the power tool.

[0034] In some embodiments, the folding buckle mechanism 122 comprises a first folding arm 1221 and a second folding arm 1222. The first folding arm 1221 is rotatably connected to one end of the main body 112. The first folding arm 1221 has opposite inner and outer sides. The outer side of the first folding arm 1221 is provided with the buckle. The second folding arm 1222 is rotatably connected to the other end of the main body 112 and rotatably connected to the first folding arm 1221, so as to change the radial size of the clamping hoop 102. The first folding arm 1221 is located between the second folding arm 1222 and the main body 112. The buckle is located on the inner side of the first folding arm 1221 facing the main body 112.

[0035] The first folding arm 1221 is rotatably connected to one end of the main body 112, the second folding arm 1222 is rotatably connected to the other end of the main body 112, and the second folding arm 1222 is also rotatably connected to the first folding arm 1221. Therefore, the user can rotate the first folding arm 1221 to make the first folding arm 1221 located between the second folding arm 1222 and the main body 112, and the inner side of the first folding arm 1221 abuts against the second folding arm 1221, and the outer side of the first folding arm 1221 abuts against the main body 112, so that the buckle can be connected in the clamping groove 132. At this time, the radial size of the clamping hoop 102 is small, the clamping hoop 102 can abut against the power tool, and the buckle can be connected in the clamping groove 132. The friction between the buckle and the clamping groove 132 makes the clamping hoop 102 fixedly sleeved on the power tool, and the installation of the handle body 101 and the power tool is completed. At this time, the user can also apply an external force to the second folding arm 1222 to separate the buckle from the clamping groove 132, and separate the inner side of the first folding arm 1221 from the second folding arm 1221, and separate the outer side of the first folding arm 1221 from the main body 112, so that the radial size of the clamping hoop 102 is large, the clamping hoop 102 can not abut against the power tool and can be separated, and the separation of the handle body 101 and the power tool is completed.

[0036] In some embodiments, the auxiliary handle 100 comprises a connecting piece 103, and the handle body 101 has a blind hole 111 for placing the connecting piece 103 at one end of the clamping hoop 102, and the connecting piece 103 is used to connect the handle body 101 and the clamping hoop 102.

[0037] The connecting piece 102 can be a screw or a pin, and the blind hole 111 can be a threaded hole or a pin hole.

[0038] In the auxiliary handle provided by the embodiments of the present disclosure, the user can adjust the radial size of the clamping hoop 102 by connecting or separating the buckle from the clamping groove 132, and adjust the tension of the clamping hoop 102, so as to install or separate the handle body 101 and the tool, so that the time for separating or installing the handle body 101 and the tool can be short, and the quick assembly and disassembly of the handle body 101 and the tool can be realized, thereby improving the practicability of the auxiliary handle 100.

[0039] Figure 3 A structural schematic diagram of an auxiliary handle provided by another embodiment of the present disclosure, Figure 4 An exploded schematic diagram of an auxiliary handle provided by another embodiment of the present disclosure.

[0040] Combined with reference Figure 3 and Figure 4Some other embodiments of the present disclosure further provide an auxiliary handle 200, comprising: a handle body 201; a clamping hoop 202 connected with the handle body 201, the clamping hoop 202 being used to be sleeved on a power tool to connect the handle body 201 with the power tool; a mounting portion (not labeled), the mounting portion being configured as a part of the clamping hoop 202, the mounting portion connecting the clamping hoop 202 with the handle body 201; a locking assembly, the locking assembly being used to adjust the tension of the clamping hoop 202 and to position the clamping hoop 202 at multiple positions of the power tool; wherein the mounting portion and the locking assembly are angularly arranged on a circumferential surface of the clamping hoop 202.

[0041] The locking assembly is a movable handle 203, the mounting portion is a bottom plate connected with the handle body 201 on the clamping hoop 202, an included angle between the mounting portion and the movable handle 203 is less than 180 degrees, the movable handle 203 is rotatably connected with the clamping hoop 202, the movable handle 203 also abuts against an end of the clamping hoop 202 away from the handle body 201, and the movable handle 203 is rotated to change a radial dimension of the clamping hoop 202 in an axial direction X of the handle body 201, so as to install or separate the handle body 201 from the power tool.

[0042] The handle body 201 is used for a user to hold.

[0043] The clamping hoop 202 is used to be sleeved on a tool to connect the handle body 201 with the tool.

[0044] In some embodiments, the clamping hoop 202 comprises a main body portion 212, a first connecting portion 222 and a second connecting portion 232, the main body portion 212 being used to be sleeved on the power tool, the first connecting portion 222 and the second connecting portion 232 being used to connect the clamping hoop 202 with the movable handle 203.

[0045] Wherein, in the axial direction X of the handle body 201, the first connecting portion 222 and the second connecting portion 232 are opposite to each other, and a distance between the first connecting portion 222 and the second connecting portion 232 is greater than 0, which provides a deformation space for the radial dimension of the clamping hoop 202 in the axial direction X of the handle body 201 to change.

[0046] The movable handle 203 is rotatably connected with the clamping hoop 202, and the movable handle 203 is also used to abut against one end of the clamping hoop 202 away from the handle body 201. Rotating the movable handle 203 can change the radial dimension of the clamping hoop 202 along the axis direction X of the handle body 201, so as to change the tension of the clamping hoop 202, so as to realize the installation or separation of the handle body 201 and the electric tool. Specifically, rotating the movable handle 203 towards the handle body 201 can make the radial dimension of the clamping hoop 202 along the axis direction X of the handle body 201 smaller, and the tension of the clamping hoop 202 tighter, so that the clamping hoop 202 can be fixedly sleeved on the electric tool, and the installation of the handle body 201 and the electric tool is completed. Rotating the movable handle 203 away from the handle body 201 can make the radial dimension of the clamping hoop 202 along the axis direction X of the handle body 201 larger, and the tension of the clamping hoop 202 looser, so that the clamping hoop 202 can not abut against the electric tool and be separated, and the separation of the handle body 201 and the electric tool is completed.

[0047] It can be understood that the radial dimension of the clamping hoop 202 along the axis direction X of the handle body 201 refers to the maximum distance between one end of the clamping hoop 202 close to the movable handle 203 and one end of the clamping hoop 202 close to the handle body 201 along the axis direction X of the handle body 201. The clamping hoop 202 has a certain elasticity, that is, the clamping hoop is an elastic clamping hoop, so that rotating the handle 213 can change the radial dimension of the clamping hoop 202 along the axis direction X of the handle body 201.

[0048] In some embodiments, the movable handle 203 includes a handle 213 and a fixing member 223. The handle 213 abuts against one end of the clamping hoop 202 away from the handle body 201, and the fixing member 223 is connected with the clamping hoop 202. The handle 213 is rotatably connected with the fixing member 223 through a damper. In this way, when a user rotates the handle 213 to a preset position, the handle 213 can be fixed after being rotated to the preset position without additional fasteners, by the resistance provided by the damper, so that the structure of the auxiliary handle 200 is more compact.

[0049] The fixing member 223 is used to be connected with the connecting portion in the clamping hoop 202.

[0050] The fixing member 223 can include a bolt 2231, a journal 2232 and a shaft sleeve 2233. The bolt 2231 and the shaft sleeve 2233 are respectively located on the opposite sides of the first connecting member and the second connecting member to connect the handle 213 and the clamping hoop 202. The journal 2232 is used to be connected with the handle 213, so that the handle 213 can rotate around the shaft sleeve 2233.

[0051] In some embodiments, the auxiliary handle 200 comprises a connecting piece 204, the handle body 201 has a blind hole 211 for placing the connecting piece 204 towards one end of the clasp 202, and the connecting piece 204 is used to connect the handle body 201 and the clasp 202.

[0052] The connecting piece 204 can be a screw or a pin, and the blind hole 211 can be a threaded hole, a pin hole, etc.

[0053] In the auxiliary handle 200 described above, the user can directly adjust the tension of the clasp 202 by rotating the movable handle 203 to separate the handle body 201 and the power tool, so that the time for separating or installing the handle body 201 and the power tool can be shorter, the handle body 201 and the power tool can be quickly disassembled and assembled, and thus the practicability of the auxiliary handle 200 can be improved.

[0054] Figure 7 A partial structure schematic diagram of an auxiliary handle is provided for still other embodiments of the present disclosure; Figure 8 A structure schematic diagram of an auxiliary handle is provided for still other embodiments of the present disclosure; Figure 9 An exploded schematic diagram of an auxiliary handle is provided for still other embodiments of the present disclosure.

[0055] In combination with reference Figures 7 to 9 Still other embodiments of the present disclosure further provide an auxiliary handle 300, comprising: a handle body 301; a clasp 302 connected with the handle body 301, the clasp 302 being used to be sleeved on a power tool to connect the handle body 301 and the power tool; a mounting portion (not labeled), the mounting portion being configured as a part of the clasp 302, and the mounting portion connecting the clasp 302 and the handle body 301; and a locking assembly, the locking assembly being used to adjust the tension of the clasp 302 and position the clasp 302 at multiple positions of the power tool; wherein the projections of the mounting portion and the locking assembly on the axial end surface of the handle body 301 at least partially overlap.

[0056] The auxiliary handle comprises a first screw 303 connected with the handle body 301, the mounting portion is an open end 312 connected with the clasp 302, and the locking assembly is a second screw 304 connected with the open end 312 and the first screw 303, the projection of the second screw 304 and the open end 312 on the axial end surface of the handle body 301 at least partially overlaps, the length of the second screw 304 is smaller than the length of the first screw 303 in the axial direction X of the handle body 301, the second screw 304 is rotated to detachably connect the second screw 304 and the first screw 303, the open end 312 is closed or separated to install or separate the handle body 301 and the power tool.

[0057] The handle body 301 is used for the user to hold.

[0058] The clamping hoop 302 is used to be sleeved on the power tool to connect the handle body 301 and the power tool. Specifically, the opening end 312 of the clamping hoop 302 can be opened by rotating the second screw 304, and the tightness of the clamping hoop 302 is loosened, so that the user can sleeve the clamping hoop 302 on the power tool, and then the opening end 312 of the clamping hoop 302 is closed by rotating the second screw 304, and the tightness of the clamping hoop 302 is tightened to fixedly connect the clamping hoop 302 and the handle body 301, and the installation of the handle body 301 and the power tool is completed. The user can open the opening end 312 of the clamping hoop 302 by rotating the second screw 304, and the tightness of the clamping hoop 302 is loosened, and the user can take off the clamping hoop 302 from the power tool to complete the separation of the handle body 301 and the power tool. Wherein, by rotating the second screw 304 with small length, the tightness of the clamping hoop 302 is adjusted to complete the installation or separation of the handle body 301 and the power tool, so that the time for separating or installing the handle body 301 and the power tool can be shorter, and the quick disassembly and assembly of the handle body 301 and the power tool can be realized, so that the practicability of the auxiliary handle 300 can be improved.
