[0055] In the description of the embodiments of the present application, it should be noted that the orientation or position relationship indicated by the term "axial" or the like is based on the attached Fig. 9 The orientation or positional relationship shown, these orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0056] The present application embodiment provides a pipeline dredging machine, see Figures 1 to 4 The pipe cleaning machine includes a housing 20, a mode switch 10, a cable drum 30 and a driving motor 40.

[0057] See also Figures 13 to 17 , the mode switch 10 of the embodiment of the present application is used to drive the cable 50 .

[0058] The cable 50 is used to extend into a pipe such as a drain pipe, and to destroy blockages in the pipe or collect debris in the pipe by moving along the extending direction of the pipe or vibrating in situ in the pipe, thereby achieving the purpose of unblocking the pipe.

[0059] The mode switch 10 switches to a corresponding mode, so that the cable 50 can move along the extension direction of the pipeline or vibrate in situ in the pipeline.

[0060] The pipe cleaning machine can be configured with the cable 50 , that is, the pipe cleaning machine configured with the cable 50 can be used as the smallest sales unit, which is equivalent to the pipe cleaning machine purchased by the user having the cable 50 included.

[0061] The pipe cleaning machine may not be provided with the cable 50 , that is, the pipe cleaning machine without the cable 50 may be used as the smallest sales unit, which is equivalent to the pipe cleaning machine purchased by the user not having the cable 50 , and the user needs to purchase the cable 50 separately.

[0062] See also Figures 6 to 17 The mode switch 10 includes a main body 11, a driving component 13 and a plurality of clamping components 12.

[0063] The main body 11 includes a mounting seat 111 having a first cable channel 111 a , and the first cable channel 111 a is used for passing cables.

[0064] The mounting base 111 is fixed to the housing 20. The cable drum 30 is rotatably disposed on one side of the mode switch 10 along the axial direction of the first cable channel 111a. The cable 50 is stored in the cable drum 30 and passes through the first cable channel 111a through the cable opening 30a of the cable drum 30.

[0065] Please continue reading Figure 7 , Figures 9 to 15 The clamping assembly 12 includes a rotatable rotating member 121. The plurality of clamping assemblies 12 are movably surrounded by the circumference of the first cable channel 111a, and the rotation axis of each rotating member 121 is inclined relative to the axial direction of the first cable channel 111a, that is, the rotation axis of each rotating member 121 is not parallel to the axial direction of the first cable channel 111a.

[0066] Fig.12 The rotating member 121 shown is a bearing having an inner ring and an outer ring, and the outer ring of the bearing can rotate on its own. In other embodiments, the rotating member 121 can be other rotatable components such as a roller.

[0067] The clamping assembly 12 may be rotatably disposed on the circumference of the first cable channel 111 a , or may be translationally disposed on the circumference of the first cable channel 111 a .

[0068] It should be noted that the movement of the clamping assembly 12 is independent of the rotation of the rotating member 121 , that is, the rotating member 121 can both rotate and, as a part of the clamping assembly 12 , move around the first cable channel 111 a with the clamping assembly 12 .

[0069] Please continue reading Figures 7 to 10 , Figures 13 to 15The driving assembly 13 includes a driving member 131, which is rotatably sleeved on the mounting seat 111. The driving member 131 rotates relative to the mounting seat 111 to move the rotating members 121 of each clamping assembly 12 toward the direction close to the first cable channel 111a to a first clamping position for clamping the cable 50 together so that the cable 50 can move along the axial direction of the first cable channel 111a. In other words, the rotating members 121 of each clamping assembly 12 are driven by the driving member 131 to move to the first clamping position.

[0070] For ease of description, the mode in which the rotating member 121 of each clamping assembly 12 is in the first clamping position is referred to as the first mode of the mode switch 10, that is, the driving member 131 can switch the mode switch 10 to the first mode by rotating relative to the mounting seat 111. In the first mode, the rotating member 121 of each clamping assembly 12 is in the first clamping position, and the rotating members 121 of each clamping assembly 12 jointly clamp the cable 50. Since each rotating member 121 can rotate, and the rotation axis of the rotating member 121 is inclined relative to the axial direction of the first cable channel 111a, the cable 50 can be driven to move along the axial direction of the first cable channel 111a during the operation of the pipe cleaning machine.

[0071] Specifically, see Figure 3 and Figure 4 The driving motor 40 is drivingly connected to the cable drum 30. When the pipeline dredging machine is in working state, a part of the cable 50 extends out of the pipeline dredging machine to be used for extending into the pipeline to perform dredging work.

[0072] When the rotating member 121 of each clamping assembly 12 is in the first clamping position, the driving motor 40 drives the cable drum 30 to rotate, so that the rotating member 121 of each clamping assembly 12 jointly drives the cable 50 to move axially along the first cable channel 111a, thereby enabling the cable 50 to move in the pipeline along the extension direction of the pipeline.

[0073] In the related art, the structure of the actuator of the pipe cleaning machine is relatively complex, and the operator usually needs at least three operating steps to move the rotating part in the actuator to a position that can drive the cable to move axially along the cable channel. The operation process is cumbersome and inconvenient.

[0074] The mode switch 10 of the embodiment of the present application is provided with a mounting seat 111 having a first cable channel 111a and a plurality of clamping assemblies 12 having rotatable rotating members 121. The plurality of clamping assemblies 12 are movably surrounded by the circumference of the first cable channel 111a, and the rotation axis of each rotating member 121 is inclined relative to the axial direction of the first cable channel 111a. At the same time, the mode switch 10 is also provided with a driving member 131 rotatably sleeved on the mounting seat 111. The driving member 131 can move the rotating members 121 of each clamping assembly 12 toward the direction close to the first cable channel 111a to the first clamping position for clamping the cable 50 together by rotating relative to the mounting seat 111, so that the cable 50 can move along the axial direction of the first cable channel 111a. The operation steps of switching the mode switch 10 to enable the cable 50 to achieve axial movement are relatively simple, which improves the convenience of operation.

[0075] In one embodiment, the driving motor 40 can drive the cable drum 30 to rotate forward, so that the rotating parts 121 of each clamping assembly 12 jointly drive the cable 50 to move in a first direction along the axial direction of the first cable channel 111a. The driving motor 40 can drive the cable drum 30 to rotate reversely, so that the rotating parts 121 of each clamping assembly 12 jointly drive the cable 50 to move in a second direction opposite to the first direction along the axial direction of the first cable channel 111a. In other words, the driving motor 40 can rotate forward or reverse, thereby driving the cable drum 30 to rotate forward or reverse.

[0076] Specifically, the first direction and the second direction are two opposite moving directions. For example, the first direction may be the direction in which the cable 50 extends to the outside of the pipe cleaning machine, that is, the forward direction of the cable 50. Correspondingly, the second direction is the direction in which the cable 50 moves into the cable drum 30, that is, the backward direction of the cable 50. In other embodiments, the first direction may be the backward direction of the cable 50, and the second direction may be the forward direction of the cable 50.

[0077] The driving motor 40 drives the cable drum 30 to rotate forward to move the cable 50 in a first direction along the axial direction of the first cable channel 111a, and drives the cable drum 30 to rotate reversely to move the cable 50 in a second direction opposite to the first direction along the axial direction of the first cable channel 111a. This allows the pipe cleaning machine to move the cable 50 forward or backward in the same mode without switching between multiple modes. This can further simplify the operating steps of the pipe cleaning machine and improve the convenience of operating the pipe cleaning machine.

[0078] In one embodiment, please refer to Figure 5 and Figure 7 The driving assembly 13 may be provided with a positioning protrusion 134 on the driving member 131. Figure 7The positioning protrusion 134 shown is a spring sheet. In other embodiments, the positioning protrusion 134 may also be a protrusion structure integrally formed with the driving member 131. The housing 20 may be provided with a first positioning groove 20a. When the rotating member 121 of each clamping assembly 12 is in the first clamping position, the positioning protrusion 134 may be inserted into the first positioning groove 20a to constrain the driving member 131 to prevent the driving member 131 from rotating, thereby ensuring that the rotating member 121 of each clamping assembly 12 can be maintained at the first clamping position.

[0079] In one embodiment, please refer to Figure 4 , Figures 6 to 9 The mode switch 10 may be provided with a force member 14, which moves under the action of an external force to drive the driving member 131 to rotate. In other words, the operator applies force to the force member 14 to move the force member 14 and drive the driving member 131 to rotate, which is equivalent to the mode switch 10 being able to achieve mode switching manually.

[0080] The force applying member 14 is not limited to a setting position, as long as it can drive the driving member 131 to rotate. Figure 4 , Figures 6 to 9 The force applying member 14 may be a front clamp having a wire outlet 14a, which is rotatably disposed on one side of the mounting seat 111, the wire outlet 14a is connected to the first cable channel 111a, and the front clamp rotates under the action of an external force to drive the driving member 131 to rotate.

[0081] Specifically, the cable 50 can extend to the outside of the pipe cleaning machine through the cable outlet 14a.

[0082] In order to facilitate the operator to apply force, at least the part of the mode switch 10 where the front clamp is set can be exposed outside the housing 20. The front clamp can be rotatably connected to the housing 20, and can also be rotatably connected to the mounting seat 111 and other structures.

[0083] The operator rotates the front clamp to cause the front clamp to drive the driving member 131 to rotate.

[0084] The front clamp drives the driving member 131 to rotate, which not only facilitates the operation of the operator, but also makes the structure of the mode switch 10 simple and compact.

[0085] In other embodiments, the mode switch 10 may not be provided with the force applying member 14 . For example, the operator may directly rotate the driving member 131 , or the driving member 131 may also be rotated by electrical control.

[0086] In one embodiment, please refer to Figure 7 , Figures 9 to 15The clamping assembly 12 may include a fixed seat 122 movably disposed on the mounting seat 111, and the rotating member 121 is disposed on the fixed seat 122. The driving member 131 pushes the fixed seat 122 of each clamping assembly 12 during the rotation process to move the rotating member 121 of each clamping assembly 12 to the first clamping position.

[0087] That is to say, during the rotation process, the driving member 131 can push the fixed seat 122 of each clamping assembly 12 to make the rotating member 121 of each clamping assembly 12 move along with the fixed seat 122, thereby enabling the rotating member 121 of each clamping assembly 12 to move to the first clamping position.

[0088] Fig.11 The fixed seat 122 shown is rotatably disposed on the mounting seat 111 . The fixed seat 122 of each clamping assembly 12 rotates under the thrust of the driving member 131 , so that the rotating member 121 of each clamping assembly 12 moves to the first clamping position.

[0089] See also Fig.11 The rotation axis of the fixing seat 122 may be parallel to the axial direction of the first cable channel 111a, so that the fixing seat 122 rotates around the rotation axis under the drive of the driving member 131. In other embodiments, the rotation axis of the fixing seat 122 may also be inclined relative to the axial direction of the first cable channel 111a.

[0090] In order to facilitate the driving member 131 to push the fixing seat 122 of each clamping assembly 12 during the rotation process, for example, refer to Fig.11 , Figures 13 to 15 The driving member 131 can be provided with a wall body 131c surrounding the circumference of the plurality of clamping components 12. During the rotation of the driving member 131, the wall body 131c pushes the fixing seat 122 of each clamping component 12. That is, a thrust can be applied to the fixing seat 122 of each clamping component 12 through the wall body 131c.

[0091] See also Fig.11 and Fig.15 The driving member 131 may be provided with a first protrusion 131d on the inner surface of the wall 131c, the first protrusion 131d protruding from the inner surface and corresponding to the clamping assembly 12. A second protrusion 122a may be provided on one side of each fixing seat 122 close to the wall 131c, and each first protrusion 131d may abut against the second protrusion 122a of the corresponding fixing seat 122 to push the corresponding fixing seat 122.

[0092] See also Fig.11 , Fig.12 and Fig.15The clamping assembly 12 may further be provided with a twistable third elastic reset member 123 , and the third elastic reset member 123 abuts against the fixing seat 122 .

[0093] The third elastic reset member 123 can facilitate the reset of each fixing seat 122. Specifically, when the driving member 131 drives the fixing seat 122 of each clamping assembly 12 to rotate, the third elastic reset member 123 generates elastic deformation through twisting, and when the driving member 131 rotates in the opposite direction relative to the mounting seat 111, the fixing seat 122 can be reset under the elastic force of the third elastic reset member 123.

[0094] In other embodiments, the fixing seat 122 may also be slidably connected to the mounting seat 111. Under the thrust of the driving member 131, the fixing seat 122 of each clamping assembly 12 slides toward the first cable channel 111a, so that the rotating member 121 of each clamping assembly 12 moves to the first clamping position.

[0095] In addition, for the fixing seat 122 slidably connected to the mounting seat 111 , the clamping assembly 12 may also be provided with a retractable fourth elastic reset member, which is retracted along the sliding direction of the mounting seat 111 to achieve the reset of the mounting seat 111 .

[0096] In one embodiment, please refer to Figures 6 to 10 The main body 11 also includes a clutch assembly 112 that can rotate relative to the mounting seat 111. The clutch assembly 112 includes a seat body 1121 having a second cable channel 1121a and a plurality of clamping arms 1122 that movably surround the second cable channel 1121a. The clamping arms 1122 can be rotatably disposed around the second cable channel 1121a or can be translatively disposed around the second cable channel 1121a. The seat body 1121 is disposed on one side of the mounting seat 111. The second cable channel 1121a is connected to the first cable channel 111a to pass the cable 50 together.

[0097] See also Fig.16 and Fig.17The driving member 131 can also rotate relative to the mounting seat 111 to move each clamping arm 1122 toward the direction close to the second cable channel 1121a to the second clamping position for clamping the cable 50 together, so as to prevent the cable 50 from moving axially along the first cable channel 111a. That is, each clamping arm 1122 moves to the second clamping position under the drive of the driving member 131. When each clamping arm 1122 is in the second clamping position, each clamping arm 1122 clamps the cable 50 together, and the cable 50 cannot move axially along the first cable channel 111a, that is, the cable 50 cannot move forward or backward along the axial direction of the first cable channel 111a. When the rotating member 121 of each clamping assembly 12 is in the first clamping position, each clamping arm 1122 is separated from the cable 50. When each clamping arm 1122 is in the second clamping position, the rotating member 121 of each clamping assembly 12 is separated from the cable 50.

[0098] Specifically, for ease of description, the mode when each clamping arm 1122 is in the second clamping position is referred to as the second mode of the mode switcher 10 , and the driving member 131 can switch to either the first mode or the second mode by rotating relative to the mounting base 111 .

[0099] See also Fig.14 In the first mode, the rotating member 121 of each clamping assembly 12 is maintained in the first clamping position, and each clamping arm 1122 does not contact the cable 50, that is, each clamping arm 1122 does not clamp the cable 50. When the driving motor 40 drives the cable drum 30 to rotate, the clutch assembly 112 does not rotate with the cable drum 30. Therefore, the cable 50 can move axially along the first cable channel 111a under the drive of the rotating member 121 of each clamping assembly 12.

[0100] See also Fig.17 In the second mode, each clamping arm 1122 is maintained at the second clamping position, and the rotating member 121 of each clamping assembly 12 does not contact the cable 50. Each clamping arm 1122 clamps the cable 50 together, so that the cable 50 cannot move forward or backward along the axial direction of the first cable channel 111a. Since the clutch assembly 112 can rotate relative to the mounting seat 111, the clutch assembly 112 can rotate with the cable drum 30 when the driving motor 40 drives the cable drum 30 to rotate. Correspondingly, the cable 50 clamped by each clamping arm 1122 can also rotate together, thereby enabling the cable 50 to achieve in-situ vibration in the pipeline.

[0101] See also Figure 5For the driving component 13 provided with a positioning protrusion 134, the housing 20 can also be provided with a second positioning groove 20b, and the second positioning groove 20b and the first positioning groove 20a are arranged at intervals along the rotation direction of the driving member 131. In the second mode, the positioning protrusion 134 can constrain the driving member 131 by being stuck in the second positioning groove 20b to prevent the driving member 131 from rotating, thereby ensuring that each of the clamping arms 1122 can be maintained in the first clamping position.

[0102] The driving member 131 rotates relative to the mounting seat 111 to move each clamping arm 1122 to the second clamping position, which can also simplify the operation steps of switching the mode switch 10 to enable the cable 50 to achieve in-situ vibration, thereby improving the convenience of operation.

[0103] For further information, see Fig. 9 The mode switch 10 can also be set to a third mode in which the rotating member 121 of each clamping assembly 12 and each clamping arm 1122 are separated from the cable 50. The driving member 131 rotates relative to the mounting seat 111 to switch the mode switch 10 between the first mode, the second mode and the third mode.

[0104] That is, in the third mode, the rotating member 121 of each clamping assembly 12 and each clamping arm 1122 do not clamp the cable 50. The driving member 131 rotates relative to the mounting seat 111 to switch the mode switch 10 between the first mode, the second mode and the third mode.

[0105] The third mode can be used to replace the cable 50. Specifically, in the third mode, the pipe cleaning machine can remain in a closed state. Since the rotating parts 121 of each clamping assembly 12 and each clamping arm 1122 do not clamp the cable 50, the operator can pull the cable 50 in the pipe cleaning machine out of the first cable channel 111a to the outside of the pipe cleaning machine, and then insert the replaced cable 50 into the cable reel 30 through the first cable channel 111a. Since the cable 50 has a certain rigidity, the cable 50 can be naturally wound around the cable reel 30 after entering the cable reel 30, thereby completing the replacement of the cable 50.

[0106] Exemplarily, when the driving member 131 is in the initial position, the mode switch 10 may be in the third mode.

[0107] For further information, see Figure 5For the mode switch 10 in which the positioning protrusion 134 is provided on the driving member 131, the housing 20 can also be provided with a third positioning groove 20c. Along the rotation direction of the driving member 131, the third positioning groove 20c is respectively spaced apart from the first positioning groove 20a and the second positioning groove 20b. In the third mode, the positioning protrusion 134 can also constrain the driving member 131 by being snapped into the third positioning groove 20c to prevent the driving member 131 from rotating.

[0108] By setting the third mode, the cable 50 can be replaced without disassembling the device, thereby improving the convenience of replacing the cable 50.

[0109] In one embodiment, please refer to Figures 6 to 10 , Fig.16 and Fig.17 , each clamping arm 1122 can rotatably surround the circumference of the second cable channel 1121a, and the driving assembly 13 can be provided with a first transmission member 132, which is movably sleeved on the seat body 1121 and located between the driving member 131 and the plurality of clamping arms 1122. The driving member 131 pushes the first transmission member 132 to translate along the axial direction of the first cable channel 111a during the rotation process, so that the first transmission member 132 applies a driving force along the axial direction of the first cable channel 111a to each clamping arm 1122, so that each clamping arm 1122 rotates toward the direction close to the second cable channel 1121a to the second clamping position.

[0110] That is to say, the rotation axis of each clamping arm 1122 is not parallel to the axial direction of the first cable channel 111a, and the driving member 131 rotates relative to the mounting base 111, so that when the mode switch 10 is switched to the second mode, its own rotation is converted into a linear motion of the first transmission member 132, so that the first transmission member 132 transmits the driving force of the driving member 131 to each clamping arm 1122, thereby causing each clamping arm 1122 to rotate in a direction close to the second cable channel 1121a.

[0111] In order to enable the first transmission member 132 to achieve linear motion, the first transmission member 132 may be slidably connected to the housing 20 or other fixed structures along the axial direction of the first cable channel 111 a .

[0112] By providing the first transmission member 132 , it is convenient for the driving member 131 to apply a driving force along the axial direction of the first cable channel 111 a to each clamping arm 1122 .

[0113] Please continue reading Figure 8 , Fig.16 and Fig.17The driving member 131 may be provided with a third protrusion 131a protruding in a direction close to the first transmission member 132, and the first transmission member 132 may be provided with a fourth protrusion 132a protruding in a direction close to the driving member 131. The third protrusion 131a may abut against the fourth protrusion 132a to push the first transmission member 132 to translate along the axial direction of the first cable channel 111a, thereby facilitating the driving member 131 to apply thrust to the first transmission member 132.

[0114] For further information, see Figure 8 , Fig.16 and Fig.17 The third protrusion 131a can be provided with a first guide inclined surface 131b abutting against the fourth protrusion 132a. When the driving member 131 rotates relative to the mounting seat 111 to switch the mode switch 10 to the second mode, the fourth protrusion 132a slides along the first guide inclined surface 131b. Under the guidance of the first guide inclined surface 131b, the first transmission member 132 can be smoothly translated along the axial direction of the first cable channel 111a.

[0115] See also Figure 8 , Fig.16 and Fig.17 The fourth protrusion 132a may also be provided with a second guide slope 132b abutting against the third protrusion 131a. When the driving member 131 rotates relative to the mounting seat 111 to switch the mode switch 10 to the second mode, the third protrusion 131a slides along the second guide slope 132b, and under the guidance of the second guide slope 132b, the first transmission member 132 can smoothly translate along the axial direction of the first cable channel 111a.

[0116] Figure 8 The third protrusion 131a shown is provided with a first guiding bevel 131b, and the fourth protrusion 132a is provided with a second guiding bevel 132b. When the driving member 131 rotates relative to the mounting seat 111 to switch the mode switch 10 to the second mode, the first guiding bevel 131b abuts against the second guiding bevel 132b. Under the interaction between the first guiding bevel 131b and the second guiding bevel 132b, the first transmission member 132 can be better guided to smoothly translate along the axial direction of the first cable channel 111a. In other embodiments, the third protrusion 131a may be provided with the first guiding bevel 131b, while the fourth protrusion 132a may not be provided with the second guiding bevel 132b, or the fourth protrusion 132a may be provided with the second guiding bevel 132b, while the third protrusion 131a may not be provided with the first guiding bevel 131b.

[0117] In one embodiment, please refer to Figures 7 to 10 , Fig.16 and Fig.17 The clutch assembly 112 can also be provided with a second transmission member 1123, and the second transmission member 1123 is movably arranged on the seat body 1121 and is located between the first transmission member 132 and the plurality of clamping arms 1122. Each clamping arm 1122 is rotatably connected to the seat body 1121 and is guided and matched with the second transmission member 1123. During the axial translation of the first cable channel 111a by the first transmission member 132, the second transmission member 1123 is pushed to translate along the axial direction of the first cable channel 111a, so that the second transmission member 1123 guides each clamping arm 1122 to rotate toward the direction close to the second cable channel 1121a.

[0118] That is, the second transmission member 1123 can be provided to guide each clamping arm 1122 to rotate toward the second cable channel 1121a to ensure that the rotation angle of each clamping arm 1122 can be roughly consistent, thereby ensuring that each clamping arm 1122 can clamp the cable 50 in the second mode.

[0119] To facilitate installation of the second transmission member 1123, for example, refer to Figure 7 and Fig.10 The second transmission member 1123 can be movably mounted on the seat body 1121 .

[0120] See also Figure 7 , Fig.10 and Fig.17 The clamping arm 1122 may be provided with a first guide portion 1122a, and the second transmission member 1123 may be provided with a second guide portion 1123a corresponding to the first guide portion 1122a of each clamping arm 1122, and the first guide portion 1122a is guided and matched with the second guide portion 1123a.

[0121] The guiding and matching manner of the first guide portion 1122a and the second guide portion 1123a is not limited. For example, please refer to Figure 7 and Fig. 9 The first guide portion 1122a may be a first guide column, and the second guide portion 1123a may be a first guide groove, and the extension direction of the first guide groove intersects with the axial direction, for example, Fig. 9 The extending direction of the first guide groove is perpendicular to the axial direction of the first cable channel 111a. In other embodiments, the extending direction of the first guide groove may be oblique to the axial direction of the first cable channel 111a. The first guide post is slidably disposed in the corresponding first guide groove. The first guide post slides in the first guide groove to guide each clamping arm 1122 to rotate toward the direction close to the second cable channel 1121a.

[0122] In other embodiments, the first guide portion 1122a may be a first guide groove, and the second guide portion 1123a may be a first guide column.

[0123] In one embodiment, please refer to Figure 7 and Fig. 9 The driving assembly 13 may be provided with a retractable first elastic reset member 133, which is disposed between the first transmission member 132 and the second transmission member 1123 and is retractable along the axial direction of the first cable channel 111a.

[0124] The first elastic reset member 133 can be provided to facilitate the reset of the first transmission member 132. Specifically, when the first transmission member 132 pushes the second transmission member 1123 to translate along the axial direction of the first cable channel 111a, the first elastic reset member 133 is compressed, and when the driving member 131 rotates relative to the mounting seat 111 to switch the mode switch 10 from the second mode to the first mode or other modes, the first transmission member 132 is reset under the elastic force of the first elastic reset member 133.

[0125] In one embodiment, please refer to Figure 7 and Figure 8 The clutch assembly 112 may be provided with a retractable second elastic reset member 1124, which is disposed between the second transmission member 1123 and the seat body 1121 and is retractable along the axial direction of the first cable channel 111a.

[0126] The second elastic reset member 1124 can be provided to facilitate the reset of the second transmission member 1123. Specifically, when the first transmission member 132 pushes the second transmission member 1123 to translate along the axial direction of the first cable channel 111a, the second elastic reset member 1124 is compressed, and when the driving member 131 rotates relative to the mounting seat 111 to switch the mode switch 10 from the second mode to the first mode or other modes, the second transmission member 1123 is reset under the elastic force of the second elastic reset member 1124.

[0127] In one embodiment, please refer to Figure 7 and Figure 8 The second transmission member 1123 may be provided with a second guide column 1123b extending along the axial direction of the first cable channel 111a, and the seat body 1121 may be provided with a second guide groove 1121b, and the second guide column 1123b movably extends into the second guide groove 1121b to guide the axial translation of the second transmission member 1123 along the first cable channel 111a.

[0128] In some other embodiments, the seat body 1121 may be provided with a second guide column 1123 b extending along the axial direction of the first cable channel 111 a , and the second transmission member 1123 may be provided with a second guide groove 1121 b .

[0129] In addition, for the clutch assembly 112 provided with the second elastic reset member 1124, for example, refer to Figure 8The second elastic reset member 1124 can be sleeved on the second guide column 1123b.

[0130] It should be noted that each clamping arm 1122 is not limited to being moved to the second clamping position under the drive of the driving member 131. For example, in other embodiments, the driving component 13 may also be provided with other driving structures, and each clamping arm 1122 is moved to the second clamping position under the drive of the driving structure.
