[0006] In the garment steamer proposed by the utility model, the second opening of the heat insulation cover provides a certain movement space for the first cable when the handle assembly rotates relative to the shell. The first cable can move at the second opening of the heat insulation cover, thereby avoiding excessive stretching of the first cable, thereby achieving the goal of allowing the handle assembly to rotate smoothly while avoiding damage to the first cable.

[0007] The garment steamer includes a shell, a handle assembly, a heating assembly, an electronic control assembly, a heat insulation cover and a first cable. The shell is the main structural component of the garment steamer, which can be used for installing components and can also protect the components located therein.

[0008] The handle assembly can rotate relative to the shell, so as to control the garment steamer to iron clothes at different angles. The axis along which the handle assembly rotates relative to the shell is the first axis, and the handle assembly is provided with a wiring channel.

[0009] The heating component is arranged in the shell, and the heating component can heat the liquid to convert the liquid into water vapor, so that the hanging iron can realize the ironing function.

[0010] The electric control assembly is arranged in the handle assembly, so that the user can operate the garment steamer while holding the garment steamer through the handle assembly.

[0011] The heat insulation cover covers the heating component, and the heat insulation cover forms a heat insulation barrier in the shell, which separates the heating component from other components in the shell and protects the safety of other components in the shell.

[0012] The heat insulation cover covers a heating component, and a second opening is provided on the heat insulation cover. The first end of the first cable is connected to the heating component.

[0029] In this technical solution, the utility model sets up a wiring channel, and the distance between the side of the wiring channel close to the handle assembly and the second opening is defined as a first distance, and the length of the first cable between the side of the wiring channel close to the handle assembly and the second opening is a first length, and the first length is greater than or equal to 1.2 times the first distance, which ensures that the first cable has enough margin for bending in the wiring channel, avoiding the compression phenomenon caused by the first cable being too short.

[0030] At the same time, the first length is less than or equal to 3 times the first distance, which prevents the first cable from being loosened and possibly entangled due to being too long, and also avoids excessive stretching of the first cable during use.

[0031] In some technical solutions of the present invention, optionally, the garment steamer further includes a protective cover, which is located between the heat insulation cover and the shell, and covers the first cable and the second cable into a wire harness.

[0032] In this technical solution, the garment steamer also includes a protective cover, which is located between the heat insulation cover and the shell, and wraps the first cable and the second cable into a wire harness, thereby protecting the first cable and the second cable, improving the toughness of the first cable and the second cable, and improving the neatness of the layout inside the garment steamer.

[0033] In some technical schemes of the utility model, optionally, the handle assembly includes a first body, a first gripping portion and a second gripping portion, the first body is connected to the shell, the water tank is installed on the first body, the side wall of the first body is provided with a groove, and the groove is recessed toward the interior of the first body; the first gripping portion is connected to the first body; the second gripping portion is connected to the first gripping portion, and the second gripping portion and the first gripping portion enclose a second installation cavity, and the second gripping portion and the outer wall of the first body enclose at least part of the wiring channel.

[0034] In this technical solution, the utility model arranges the component structure of the handle assembly, and the handle assembly is arranged in combination with practicality and assembly convenience. Specifically, the handle assembly includes a first body, a first gripping portion, and a second gripping portion.

[0035] The above modular arrangement not only improves the maintainability of the handle assembly, but also simplifies the assembly process of the handle assembly.

[0036] The first body is connected to the shell, and the first body is the basic component of the handle assembly. The first body is provided with the water tank for storing water required for ironing. Through the above arrangement, the water tank and the handle assembly are integrated, which is convenient for user operation and management.

[0037] The first gripping portion is connected to the first body, ensuring that the user can hold the handle comfortably and stably when using the garment steamer.

[0038] The second gripping portion is connected to the first gripping portion, and the two of them enclose a second installation cavity. The second installation cavity can be used to install some key electronic components or control components to support various functions of the handle assembly.

[0039] A wiring channel is also provided between the second grip and the first body. The traditional wiring channel is a closed annular structure, which is difficult to assemble the first cable. The present application sets the handle assembly as the first grip and the second grip, and sets a wiring channel between the second grip and the first body. The wiring channel is no longer a closed annular structure, but becomes open. When arranging the first cable in the wiring channel, the first grip and the second grip can be disassembled, making the assembly process of the first cable easier and greatly improving the ease of use of the shell assembly.

[0040] The side wall of the first body is recessed inwardly, so that the space of the wiring channel is larger, thereby avoiding squeezing of the first cable.

[0041] In addition, this design also helps to reduce the encroachment of the wiring channel on the space where the water tank is located. Since the wiring channel is open, it will not take up too much space like a closed ring structure, thereby ensuring that the water tank has sufficient volume to store enough water.

[0042] In some technical solutions of the present utility model, optionally, the second gripping portion includes an extending portion, and an inner wall of the extending portion and an inner wall of the groove enclose a wiring channel.

[0043] In this technical solution, the handle assembly also includes an extension portion, and the provision of the extension portion helps to improve the user experience and protect the first cable.

[0044] The inner wall of the extension part and the inner wall of the groove enclose a wiring channel, and the extension part forms a guiding and protective function. The extension part provides a guide for the first cable, ensuring that the first cable can pass smoothly along a predetermined path. The guidance prevents the first cable from running around in the installation groove, reduces interference and friction between the first cable and other internal structures, and thus protects the safety of the first cable.

[0045] Since the extension portion extends into the installation groove, an isolation layer is formed between the first cable and any sharp corners that may exist, thereby effectively preventing the sharp corners at the connection from scratching the first cable.

[0046] In some technical solutions of the present invention, optionally, the area outside the groove on the outer wall of the first body is the first area; the first area of ​​the outer wall of the first body and the outer wall of the extension portion are a continuous wall surface.

[0047] In this technical solution, the area outside the groove on the outer wall of the first body is the first area, and the first area of ​​the outer wall of the first body and the outer wall of the extension part are continuous wall surfaces, so that the shapes of the first body and the extension part are relatively continuous, and there are no relatively disconnected parts, thereby avoiding scratches on the first cable.

[0048] At the same time, the shapes of the first body and the extension portion are relatively continuous, which can also better guide the first cable so that the first cable naturally fits the outer wall of the extension portion and the first body, making it easier to arrange the first cable.

[0049] In some technical solutions of the present utility model, optionally, the groove extends from the connection between the first body and the first gripping portion to the bottom of the first body.

[0050] In this technical solution, the groove extends from the connection between the first body and the first gripping portion to the bottom of the first body. The groove is opposite to the wiring channel, so that the space of the wiring channel is larger and can better accommodate the first cable. When the handle assembly is rotated, the first cable can have a larger moving space.

[0051] In some technical solutions of the utility model, optionally, the shell is provided with a mounting groove; at least a part of the first body is located in the mounting groove, and the inner wall of the mounting groove, the outer wall of the first body and the second gripping portion enclose a wiring channel.

[0052] In this technical solution, the shell is provided with a mounting groove, and the mounting groove forms an inwardly recessed space.

[0053] At least a portion of the first body is located in the mounting groove, and an inner wall of the mounting groove, an outer wall of the first body and the second gripping portion surround a wiring channel.

[0054] The wiring channel is used to accommodate or guide the first cable, ensuring that the first cable can pass through or be arranged in the channel in an orderly and safe manner.

[0055] A relatively closed wiring channel can be formed by the inner wall of the installation groove, the outer wall of the first body and the second gripping portion. Since the wiring channel is closed, the probability of leakage of the first cable is greatly reduced, thereby improving the safety and stability of the first cable.

[0056] In some technical solutions of the present utility model, optionally, a first opening is provided on a side wall of the installation slot opposite to the groove, and the wiring channel is connected to the housing through the first opening.

[0057] In this technical solution, a first opening is provided on the side wall of the installation groove, and the wiring channel is connected with the housing through the first opening, so that the first cable can enter the housing in an orderly and safe manner.

[0058] Specifically, in order to prevent the first cable from being damaged or affected by the external environment when passing through the first opening, protective measures can be set at the cable inlet, such as installing a wire sheath or wrapping the edge of the opening with a soft material, thereby increasing the service life of the first cable and improving the safety of the overall structure.

[0059] In some technical schemes of the utility model, optionally, a first chamfer or a first rounded corner is provided at the connection between the extension portion and the second grip portion; and / or a second chamfer or a second rounded corner is provided on the side of the extension portion away from the second grip portion; and / or a third chamfer or a third rounded corner is provided at the connection between the side wall of the first body and the bottom wall of the first body; and / or the shell is provided with a fourth chamfer or a fourth rounded corner, and the fourth chamfer or the fourth rounded corner is arranged along the edge of the first opening.

[0060] In this technical solution, on the one hand, a first chamfer or a first rounded corner is provided at the connection between the extension portion and the second grip portion, and the sharp edges at the connection between the extension portion and the second grip portion are smoothed, and the friction and potential scratch risk when the first cable contacts these edges are greatly reduced.

[0061] In addition, the first chamfer or the first rounded corner can also be used to guide the arrangement of the first cable, so that the first cable extends in the correct direction in the wiring channel.

[0062] On the other hand, a second chamfer or a second rounded corner is provided on a side of the extension portion away from the second gripping portion, so that the contact between the first cable and the edge of the extension portion becomes smoother and the risk of scratching is reduced accordingly.

[0063] In addition, the second chamfer or the second rounded corner can also guide the arrangement of the first cable so that the first cable extends in the correct direction in the wiring channel.

[0064] On the other hand, a first chamfer or a first rounded corner is provided at the connection between the extension portion and the second grip portion, and a second chamfer or a second rounded corner is provided on the side of the extension portion away from the second grip portion. Through multiple chamfers, the probability of scratching the first cable is significantly reduced, thereby improving the product's safety and user satisfaction.

[0065] In this technical solution, a third chamfer or a third rounded corner is provided at the connection between the side wall of the first body and the bottom wall of the first body. When the first cable passes through the inside of the first body, the first cable is easily scratched or damaged at the connection between the side wall and the bottom wall due to the possible presence of sharp edges or corners. By providing the third chamfer or the third rounded corner, these sharp edges are smoothed, thereby reducing the friction and potential scratching risk when the first cable contacts these edges.

[0066] The presence of the third chamfer or the third rounded corner can also improve the smoothness of the first cable passing through the area, thereby avoiding damage to the first cable caused by being stuck or excessively bent.

[0067] On the other hand, the first opening is the main passage for the first cable to enter or leave the housing, and if the edge of the first opening is too sharp, the first cable is easily scratched when entering or leaving. By arranging the fourth chamfer or the fourth rounded corner on the edge of the first opening, these edges are smoothed, reducing the contact area and friction between the first cable and the edge, thereby reducing the risk of scratching.

[0068] The provision of the fourth chamfer or the fourth rounded corner can also enhance the overall aesthetics of the housing and improve the user experience, because the user does not have to worry about the first cable being scratched or damaged when entering or exiting.

[0069] On the other hand, the connection between the side wall of the first body and the bottom wall of the first body is provided with a third chamfer or a third rounded corner, and the shell is provided with a fourth chamfer or a fourth rounded corner, and the fourth chamfer or the fourth rounded corner is arranged along the edge of the first opening. By providing the third chamfer or the third rounded corner and the fourth chamfer or the fourth rounded corner, the first cable can be effectively protected from scratches, thereby improving the safety and reliability of the garment steamer.

The second opening 172 is provided at one end of the heat insulation cover 170 close to the water pump 182, which facilitates the installation of the second cable 184 and the connection and arrangement of the control circuit in the garment steamer 100.

[0112] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of the present invention, optionally, the heat insulation cover 170 is provided with a second mounting portion 178, and the hanging steamer 100 also includes a water connector 186 and a connecting pipe 192, the water connector 186 is installed on the second mounting portion 178, and the water inlet end 188 of the water connector 186 is sleeved on the water outlet channel 198 of the water tank 125; one end of the connecting pipe 192 is inserted into the water outlet end 190 of the water connector 186, and the other end is connected to the water pump 182.

[0113] In this embodiment, the heat insulation cover 170 is further provided with a second mounting portion 178 , and the garment steamer 100 further includes a water connector 186 and a connecting pipe 192 , wherein the water connector 186 is installed on the second mounting portion 178 , thereby fixing the water connector 186 on the second mounting portion 178 .

[0114] The water inlet end 188 of the water connector 186 is sleeved on the water outlet channel 198 of the water tank 125 , and the water discharged from the water outlet channel 198 of the water tank 125 can enter the water inlet end 188 of the water connector 186 .

[0115] One end of the connecting pipe 192 is inserted into the water outlet end 190 of the water joint 186, and the other end is connected to the water pump 182. Through the connecting pipe 192 and the water joint 186, the water pump 182 can smoothly pump water out of the water tank 125 and supply it to the heating component 150, which heats it and converts it into water vapor.

[0116] Specifically, the connecting pipe 192 may also be a water inlet pipe formed on the water pump 182 .

[0117] Specifically, the connecting pipe 192 is made of plastic, and the water connector 186 is made of silicone, or a soft water connector made of polyurethane, rubber, or polyvinyl chloride. The water outlet channel 198, the connecting pipe 192, and the water connector 186 are interference-fitted after being plugged in.

[0118] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, optionally, the distance between the side of the wiring channel 124 close to the handle assembly 120 and the second opening 172 is a first distance; the length of the first cable 180 located between the side of the wiring channel 124 close to the handle assembly 120 and the second opening 172 is a first length; the first length is greater than or equal to 1.2 times the first distance, and less than or equal to 3 times the first distance.

[0119] In this embodiment, the utility model sets a wiring channel 124, and the distance between the side of the wiring channel 124 close to the handle assembly 120 and the second opening 172 is defined as a first distance, and the length of the first cable 180 between the side of the wiring channel 124 close to the handle assembly 120 and the second opening 172 is a first length, and the first length is greater than or equal to 1.2 times the first distance, which ensures that the first cable 180 has enough margin for bending in the wiring channel 124, thereby avoiding the compression phenomenon caused by the first cable 180 being too short.

[0120] At the same time, the first length is less than or equal to 3 times the first distance, which prevents the first cable 180 from being too long and causing looseness and possible entanglement, and also avoids excessive stretching of the first cable 180 during use.

[0121] like Figure 1 , Figure 2 and Fig.10 As shown, in some embodiments of the present invention, optionally, the garment steamer 100 further includes a protective cover 194, which is located between the heat insulation cover 170 and the housing 110, and covers the first cable 180 and the second cable 184 into a wire harness.

[0122] In this embodiment, the garment steamer 100 also includes a protective cover 194, which is located between the heat insulation cover 170 and the shell 110, and covers the first cable 180 and the second cable 184 into a wiring harness, thereby protecting the first cable 180 and the second cable 184, improving the toughness of the first cable 180 and the second cable 184, and improving the neatness of the layout inside the garment steamer 100.

[0123] Specifically, the color and material of the protective cover 194 match the overall design style of the garment steamer 100, making the entire product more coordinated and unified.

[0124] Specifically, the protective cover 194 includes a plastic cover, which is mainly made of materials such as PVC (polyvinyl chloride) or PE (polyethylene), etc., and provides good waterproof and anti-corrosion properties and has a low cost.

[0125] The protective sleeve 194 also includes a metal sleeve, such as an aluminum sleeve or a steel sleeve, which has high wear resistance and corrosion resistance and can withstand greater mechanical stress and external force impact.

[0126] The protective sleeve 194 also includes a rubber sleeve.

[0127] like Figure 1 and Figure 2As shown, in some embodiments of the present invention, optionally, the handle assembly 120 includes a first body 126, a first gripping portion 128 and a second gripping portion 130, the first body 126 is connected to the shell 110, the water tank 125 is installed on the first body 126, the side wall of the first body 126 is provided with a groove 127, and the groove 127 is recessed toward the interior of the first body 126; the first gripping portion 128 is connected to the first body 126; the second gripping portion 130 is connected to the first gripping portion 128, and the second gripping portion 130 and the first gripping portion 128 enclose a second installation cavity 122, and the second gripping portion 130 and the outer wall of the first body 126 enclose at least part of the wiring channel 124.

[0128] In this embodiment, the utility model sets the component structure of the handle assembly 120 , and the handle assembly 120 is set in combination with practicality and assembly convenience. Specifically, the handle assembly 120 includes a first body 126 , a first gripping portion 128 and a second gripping portion 130 .

[0129] The above modular arrangement not only improves the maintainability of the handle assembly 120 , but also simplifies the assembly process of the handle assembly 120 .

[0130] The first body 126 is connected to the shell 110. The first body 126 is the basic component of the handle assembly 120. The first body 126 is provided with the water tank 125 for storing water required for ironing. Through the above configuration, the water tank 125 and the handle assembly 120 are integrated to facilitate user operation and management.

[0131] The first gripping portion 128 is connected to the first body 126 , ensuring that the user can hold the handle comfortably and stably when using the garment steamer 100 .

[0132] The second gripping portion 130 is connected to the first gripping portion 128 , and the two define a second mounting cavity 122 . The second mounting cavity 122 may be used to mount some key electronic components or control parts to support various functions of the handle assembly 120 .

[0133] A wiring channel 124 is also provided between the second grip portion 130 and the first body 126. The conventional wiring channel 124 is a closed annular structure, which makes it difficult to assemble the first cable 180. In the present application, by providing the handle assembly 120 with the first grip portion 128 and the second grip portion 130, and providing the wiring channel 124 between the second grip portion 130 and the first body 126, the wiring channel 124 is no longer a closed annular structure, but becomes open. When arranging the first cable 180 in the wiring channel 124, the first grip portion 128 and the second grip portion 130 can be disassembled, so that the assembly process of the first cable 180 becomes simpler, and the ease of use of the shell assembly is greatly improved.

[0134] The sidewall of the first body 126 is recessed inward, so that the space of the wiring channel 124 is larger, thereby avoiding squeezing of the first cable 180 .

[0135] In addition, this design also helps to reduce the encroachment of the wiring channel 124 on the space where the water tank 125 is located. Since the wiring channel 124 is open, it will not take up too much space like a closed annular structure, thereby ensuring that the water tank 125 has sufficient volume to store enough water.

[0136] Specifically, the first grip portion 128 and the first body 126 are an integrated structure, which simplifies the assembly process of the garment steamer 100.

[0137] Specifically, the first gripping portion 128 and the second gripping portion 130 are split structures, so that the wiring channel 124 is an open channel, thereby reducing the difficulty of wiring.

[0138] Specifically, on one hand, the water tank 125 can be disposed inside the first body 126 .

[0139] On the other hand, the water tank 125 may also be disposed on the first body 126 and located outside the first body 126 .

[0140] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, optionally, the second gripping portion 130 includes an extending portion 132 , and the inner wall of the extending portion 132 and the inner wall of the groove 127 enclose a wiring channel 124 .

[0141] In this embodiment, the handle assembly 120 further includes an extension portion 132 . The provision of the extension portion 132 helps to improve the user experience and protect the first cable 180 .

[0142] The inner wall of the extension portion 132 and the inner wall of the groove 127 enclose a wiring channel 124, and the extension portion 132 forms a guiding and protective function. The extension portion 132 provides a guide for the first cable 180 to ensure that the first cable 180 can smoothly travel along a predetermined path. The guidance prevents the first cable 180 from running around in the installation groove 114, reduces the interference and friction between the first cable 180 and other internal structures, and thus protects the safety of the first cable 180.

[0143] Since the extension portion 132 extends into the mounting groove 114 , an isolation layer is formed between the first cable 180 and any sharp corners that may exist, thereby effectively preventing the sharp corners at the connection from scratching the first cable 180 .

[0144] Specifically, the extension portion 132 and the second gripping portion 130 are an integrated structure, thereby simplifying the assembly process of the handle assembly 120 .

[0145] like Figure 1 As shown, in some embodiments of the present invention, optionally, the area outside the groove 127 on the outer wall of the first body 126 is the first area 129; the first area 129 of the outer wall of the first body 126 and the outer wall of the extension portion 132 are continuous walls.

[0146] In this embodiment, the area outside the groove 127 on the outer wall of the first body 126 is the first area 129. The first area 129 of the outer wall of the first body 126 and the outer wall of the extension portion 132 are continuous wall surfaces, so that the shapes of the first body 126 and the extension portion 132 are relatively continuous, and there are no relatively disconnected parts, thereby avoiding scratches on the first cable 180.

[0147] At the same time, the shapes of the first body 126 and the extension portion 132 are relatively continuous, which can also better guide the first cable 180 so that the first cable 180 naturally fits the outer wall of the extension portion 132 and the first body 126, making it easier to arrange the first cable 180.

[0148] like Figure 1 As shown, in some embodiments of the present invention, optionally, the groove 127 extends from the connection between the first body 126 and the first gripping portion 128 to the bottom of the first body 126 .

[0149] In this embodiment, the groove 127 extends from the connection between the first body 126 and the first gripping portion 128 to the bottom of the first body 126. The groove 127 is opposite to the wiring channel 124, so that the space of the wiring channel 124 is larger and can better accommodate the first cable 180. When the handle assembly 120 is rotated, the first cable 180 can have a larger moving space.

[0150] like Figure 2 and Figure 6 As shown, in some embodiments of the present invention, optionally, the shell 110 is provided with a mounting groove 114; at least a portion of the first body 126 is located in the mounting groove 114, and the inner wall of the mounting groove 114, the outer wall of the first body 126 and the second gripping portion 130 enclose a wiring channel 124.

[0151] In this embodiment, the housing 110 is provided with a mounting groove 114 , and the mounting groove 114 forms an inwardly recessed space.

[0152] At least a portion of the first body 126 is located in the mounting groove 114 , and the inner wall of the mounting groove 114 , the outer wall of the first body 126 , and the second gripping portion 130 enclose a wiring channel 124 .

[0153] The wiring channel 124 is used to accommodate or guide the first cable 180 to ensure that the first cable 180 can pass through or be arranged in the channel in an orderly and safe manner.

[0154] A relatively closed wiring channel 124 can be ensured to be formed by the inner wall of the mounting groove 114 , the outer wall of the first body 126 and the second gripping portion 130 . Since the wiring channel 124 is closed, the probability of leakage of the first cable 180 is greatly reduced, thereby improving the safety and stability of the first cable 180 .

[0155] like Figure 2 and Figure 6 As shown, in some embodiments of the present invention, optionally, a first opening 116 is provided on a side wall of the mounting slot 114 opposite to the groove 127 , and the wiring channel 124 is connected to the housing 110 through the first opening 116 .

[0156] In this embodiment, a first opening 116 is disposed on the side wall of the mounting groove 114 , and the wiring channel 124 is connected to the housing 110 through the first opening 116 , so that the first cable 180 can enter the housing in an orderly and safe manner.

[0157] Specifically, in order to prevent the first cable 180 from being damaged or affected by the external environment when passing through the first opening 116, protective measures can be set at the cable inlet, such as installing a wire sheath or wrapping the edge of the opening with a soft material, thereby increasing the service life of the first cable 180 and improving the safety of the overall structure.

[0158] Specifically, the connection line of the first cable 180 is the electric control component 160 - the wiring channel 124 - the first opening 116 - the second opening 172 - the heating component 150 .

[0159] Specifically, the heating assembly 150 includes a heating module and a temperature control module.

[0160] Specifically, when the handle assembly 120 rotates, the second opening 172 is in a long runway circle along the rotation direction of the handle assembly 120 , so that the freedom of the first cable 180 in the wiring channel 124 at the opening interface can be guaranteed during rotation, avoiding squeezing and bending of the first cable 180 .

[0161] Specifically, the housing 110 has a first installation cavity 112 , the wiring channel 124 is connected to the first installation cavity 112 through a first opening 116 , the first installation cavity 112 can accommodate electrical components, and the first cable 180 can enter the first installation cavity 112 in an orderly manner through the first opening 116 .

[0162] like Figure 1As shown, in some embodiments of the present invention, optionally, a first chamfer or a first rounded corner 134 is provided at the connection between the extension portion 132 and the second grip portion 130; and / or a second chamfer or a second rounded corner 136 is provided on the side of the extension portion 132 away from the second grip portion 130; and / or a third chamfer or a third rounded corner 138 is provided at the connection between the side wall of the first body 126 and the bottom wall of the first body 126; and / or the shell 110 is provided with a fourth chamfer or a fourth rounded corner 140, and the fourth chamfer or the fourth rounded corner 140 is arranged along the edge of the first opening 116.

[0163] In this embodiment, on the one hand, a first chamfer or a first rounded corner 134 is provided at the connection between the extension portion 132 and the second grip portion 130, and the sharp edges at the connection between the extension portion 132 and the second grip portion 130 are smoothed, and the friction and potential scratch risk when the first cable 180 contacts these edges are greatly reduced.

[0164] In addition, the first chamfer or the first rounded corner 134 can also be used to guide the arrangement of the first cable 180 so that the first cable 180 extends in a correct direction in the wiring channel 124 .

[0165] On the other hand, a second chamfer or a second rounded corner 136 is provided on a side of the extension portion 132 away from the second grip portion 130 , so that the contact between the first cable 180 and the edge of the extension portion 132 becomes smoother, and the risk of scratching is correspondingly reduced.

[0166] In addition, the second chamfer or the second rounded corner 136 can also be used to guide the arrangement of the first cable 180 so that the first cable 180 extends in a correct direction in the wiring channel 124 .

[0167] On the other hand, a first chamfer or a first rounded corner 134 is provided at the connection between the extension portion 132 and the second grip portion 130, and a second chamfer or a second rounded corner 136 is provided on the side of the extension portion 132 away from the second grip portion 130. Through multiple chamfers, the probability of scratching the first cable 180 is significantly reduced, thereby improving the product's safety and user satisfaction.

[0168] In this embodiment, a third chamfer or a third rounded corner 138 is provided at the connection between the side wall of the first body 126 and the bottom wall of the first body 126. When the first cable 180 passes through the inside of the first body 126, it is at the connection between the side wall and the bottom wall. Due to the sharp edges or corners that may exist, the first cable 180 is easily scratched or damaged.
