[0066] The present application provides a hinge device, which is suitable for providing a rotation range of more than 180° and ensuring good stability at multiple intermediate angles in the rotation range, thereby being beneficial to meet the diversified use requirements of users.

[0067] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0068] Embodiment one

[0069] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application. Figures 1-18 The embodiment one of the present application provides a hinge device, comprising a first rotating shaft 11, a second rotating shaft 12 and a connecting assembly 2, wherein the axis of the second rotating shaft 12 and the axis of the first rotating shaft 11 satisfy the parallel condition, the connecting assembly 2 is assembled and connected with the first rotating shaft 11 and the second rotating shaft 12, that is, the axes of the first rotating shaft 11 and the second rotating shaft 12 are arranged in parallel with a certain interval, and both are assembled and connected to the connecting assembly 2, and at least the main part of the hinge device is combined through the connecting assembly 2, when the hinge device is applied to the first body and the second body of the electronic device relative to the rotation, the first rotating shaft 11 can be fixedly connected with the first body through the first connecting piece 31, and the second rotating shaft 12 can be fixedly connected with the second body through the second connecting piece 32, for example, the first connecting piece 31 and the second connecting piece 32 are usually provided as a plate piece with a mounting hole. It should be understood that the assembly between the first rotating shaft 11 and the second rotating shaft 12 and the connecting assembly 2 allows the first rotating shaft 11 and the second rotating shaft 12 to rotate relative to the connecting assembly 2, that is, the first rotating shaft 11 at least provides the relative rotation of the first connecting piece 31 and the connecting assembly 2, and the second rotating shaft 12 at least provides the relative rotation of the second connecting piece 32 and the connecting assembly 2.

[0070] The connecting assembly 2 comprises a switching module and a control module, wherein the switching module can form a first state and a second state during the rotation of the hinge device, in the first state and the second state, the switching module can switch the rotating shaft between the first rotating shaft 11 and the second rotating shaft 12, that is, during the one-way rotation process provided by the hinge device, the switching module can form two different states allowing the rotating shaft to switch, and in any one of the two different states, the switching of the rotating shaft can be implemented. It should be noted that the one-way rotation process refers to the rotation in the same direction without changing direction in the middle, for example, the rotation opening process or the rotation closing process of the display part and the main part of the notebook computer when the hinge device is used to connect the display part and the main part of the notebook computer. The rotating shaft refers to the shaft piece currently providing rotation, and in the whole one-way rotation process, there is a rotating stage of the first rotating shaft 11 as the rotating shaft, and there is a rotating stage of the second rotating shaft 12 as the rotating shaft, and the rotating shaft needs to be switched from the first rotating shaft 11 to the second rotating shaft 12 at the junction of different rotating stages, or vice versa.

[0071] The control module includes a movable element 207 disposed between the first rotating shaft 11 and the second rotating shaft 12, and the control module is capable of controlling the movable element 207 to move in a first direction to switch the switching module between the first state and the second state, and the first direction is parallel to the axis. That is, during the switching of the switching module from the first state to the second state or vice versa, the movable element 207 of the control module moves in a direction parallel to the first rotating shaft 11 or the second rotating shaft 12. It should be noted that the movement of the movable element 207 in the first direction can be the change in position of the entire movable element 207 in the first direction, or the change in position of part of the movable element 207 in the first direction, and the first direction parallel to the axis can be that the straight line in the first direction coincides with the axis, or that the straight line in the first direction is separated from the axis by a certain distance.

[0072] The hinge device provided by the present application includes the first rotating shaft 11 and the second rotating shaft 12 that can serve as rotating shafts, and the switching module can form two states that switch the rotating shaft between the first rotating shaft 11 and the second rotating shaft 12 during the rotation provided by the hinge device, i.e. the first state and the second state, so that the hinge device can realize the switching of the rotating shaft twice during the single-direction rotation provided by the hinge device, and thus the single-direction rotation process described above becomes a three-segment rotation process shared by the two rotating shafts, i.e. one of the rotating shafts provides the first segment and the third segment of the rotation, and the other of the rotating shafts provides the second segment of the rotation between the first segment and the third segment, and thus the hinge device is suitable for providing a rotation range of more than 180°, such as in the example shown in the figure. Figures 1-4 In the example shown, the second rotating shaft 12 provides a rotation of 0° to 120° (i.e. the first connecting element 31 and the second connecting element 32 are from 0° to 120°) and a rotation of 280° to 360° (i.e. the first connecting element 31 and the second connecting element 32 are from 280° to 360°), and the first rotating shaft 11 provides a rotation of 120° to 280° (i.e. the first connecting element 31 and the second connecting element 32 are from 120° to 280°), so as to realize that the hinge device provides a relative rotation range of 360° for the first connecting element 31 and the second connecting element 32. Figures 1 to 2 Figures 3 to 4 Figures 2 to 3 Figures 1-4 In the example shown, the switching of the rotating shaft occurs at the positions shown in the figures. Figure 2 Figure 3 Figure 2 Figure 3 ​​​​​​When the switching module switches between the first and second states, all or part of the movable element 207 undergoes a positional change in a direction parallel to the rotation axis. Due to the arrangement of this movable element 207, when the switching module forms the first or second state, the hinge device can maintain a relatively stable posture at that moment, exhibiting good stability at multiple intermediate angles within the rotation range, for example, in… Figures 1-4 In the example shown, the first connector 31 and the second connector 32, in addition to Figure 1 The 0° angle attitude and Figure 4 The 360° angle posture shown has good stability and also Figure 2 The 120° angle attitude shown and Figure 3 The 280° angle posture shown exhibits good stability. It should be understood that the rotation range provided by the hinge mechanism and the specific values ​​of the two intermediate angles can be flexibly set as needed.

[0073] like Figures 5-10 As shown, in this embodiment, the switching module includes a first cam 201 fixedly disposed on the first rotating shaft 11, a second cam 204 fixedly disposed on the second rotating shaft 12, and a slider 202 located between the first cam 201 and the second cam 204; the peripheral surface of the first cam 201 has two first slots 2011, and the peripheral surface of the second cam 204 has one second slot 2041, which is formed by... Figure 18It can be seen that when one of the two first slots 2011 is opposite to the second slot 2041, the switching module forms the first state described above, and when the other of the two first slots 2011 is opposite to the second slot 2041, the switching module forms the second state described above. The first slot 2011 and the second slot 2041 are crescent-shaped recesses, and the two ends of the slider 202 are crescent-shaped protrusions corresponding to the crescent-shaped recesses. The slider 202 is installed in a slide channel formed between the two slide seats 2033 of the switching module base 203. When the switching module forms the first state or the second state, since the first slot 2011 is opposite to the second slot 2041, there is a moving space for the slider 202 to move along the slide channel. Therefore, the first cam 201 or the second cam 204 can drive the slider 202 to move along the slide channel by rotating relative to the switching module base 203, so as to realize that the slider 202 changes from being clamped with the first slot 2011 to being clamped with the second slot 2041, or changes from being clamped with the second slot 2041 to being clamped with the first slot 2011. When the slider 202 is clamped with the first slot 2011, the rotation of the first cam 201 relative to the switching module base 203 is limited, and the second cam 204 can rotate relative to the switching module base 203. Therefore, the hinge device is provided with rotation by the second rotating shaft 12 at this time, that is, the second rotating shaft 12 serves as the rotation shaft. When the slider 202 is clamped with the second slot 2041, the rotation of the second cam 204 relative to the switching module base 203 is limited, and the first cam 201 can rotate relative to the switching module base 203. Therefore, the hinge device is provided with rotation by the first rotating shaft 11 at this time, that is, the first rotating shaft 11 serves as the rotation shaft.

[0074] As Figure 5 , Figures 11-18As shown, in the embodiment, the control module includes a driving member assembled to the first rotating shaft 11 and a limiting member 206 assembled to the second rotating shaft 12, wherein the driving member is a component for driving the movement of the movable member 207, and the limiting member 206 is a component for cooperating with the movable member 207 to provide a stop point, which forms after the stop point to limit the rotation of the second rotating shaft 12 relative to the connecting assembly 2, that is, to limit the second rotating shaft 12 as a rotating shaft. In the rotating process of the first rotating shaft 11 as a rotating shaft, the movable member 207 abuts against the driving member and the limiting member 206, and the driving member can move relative to the first rotating shaft 11 to drive the movable member 207 to move in the first direction. That is, when the switching module switches between the first state and the second state, the movable member 207 abuts against the limiting member 206 to form the aforementioned stop point to limit the second rotating shaft 12 as a rotating shaft, and the first rotating shaft 11 drives the first cam 201 to rotate relative to the switching module base 203, and in this process, the part of the driving member abutting against the movable member 207 changes the position in the axial direction relative to the first rotating shaft 11, so as to realize the position change of the part of the driving member abutting against the movable member 207 in the first direction. It should be noted that the abutment of the movable member 207 against the driving member and the limiting member 206 can only correspond to a part of the whole rotating process of the first rotating shaft 11 as a rotating shaft, that is, the abutment described above does not exist all the time in the rotating process of the first rotating shaft 11 as a rotating shaft. It should be understood that the stop point formed by the abutment of the movable member 207 against the limiting member 206 needs to be removed after the sliding block 202 is clamped into the second clamping groove 2041 on the second cam 204, so that the clamping of the sliding block 202 and the second clamping groove 2041 replaces the abutment of the movable member 207 and the limiting member 206 to limit the rotation of the second rotating shaft 12 relative to the connecting assembly 2.

[0075] By arranging the driving member, the control module can be made smaller in the axial direction of the first rotating shaft 11, which is beneficial to reduce the size of the hinge device in this direction. In a preferred embodiment, the hinge device includes a first base in the shape of a plate strip hinged to the first rotating shaft 11 and the second rotating shaft 12, and the driving member includes two spacers distributed on both sides of the movable member 207 in the axial direction of the first rotating shaft 11, the spacers being axially slidably assembled to the first rotating shaft 11 through a non-circular hole, wherein the first base is located on the side of the spacer away from the movable member 207, the side of the spacer away from the movable member 207 is provided with a first cam 201 structure, and the side of the first base facing the movable member 207 is provided with a second cam 204 structure, and the first cam 201 structure and the second cam 204 structure cooperate to form an axial cam pair. Arranging the first base in the shape of a plate strip and using the spacer as the driving member are both to minimize the size of the control module in the axial direction of the first rotating shaft 11. As shown in the figure, Figures 11-17 As shown, in the embodiment, the driving member includes a first spacer 210 and a second spacer 209 located on both sides of the movable member 207, and the first base includes a control module base 208 and an intermediate base 205 (arranged between the control module base 208 and the second rotating shaft 12).Figure 5 As can be seen, the intermediate base 205 is located between the switching module base 203 and the control module base 208, and is shared by the switching module and the control module, wherein the first recess 2051 on the intermediate base 205 cooperates with the first protrusion 2101 on the first gasket 210 to form a first axial cam pair, and the second recess 2081 on the control module base 208 cooperates with the second protrusion 2091 on the second gasket 209 to form a second axial cam pair. Figure 18 As can be seen, when the hinge device is converted from the 120° posture to the 280° posture, the first rotating shaft 11 rotates as a rotating shaft relative to the first base, and the first gasket 210 and the second gasket 209 rotate with the first rotating shaft 11. During the rotation process, the first protrusion 2101 of the first gasket 210 slides into the first recess 2051 of the intermediate base 205, and the second protrusion 2091 of the second gasket 209 slides out of the second recess 2081 of the control module base 208, thereby driving the movable part 207 to move to the left in Figure 18 . Conversely, when the hinge device is converted from the 280° posture to the 120° posture, the second protrusion 2091 of the second gasket 209 slides into the second recess 2081 of the control module base 208, and the first protrusion 2101 of the first gasket 210 slides out of the first recess 2051 of the intermediate base 205, thereby driving the movable part 207 to move to the left in Figure 18 .

[0076] Specifically, in the present embodiment, the first cam 201 structure includes two protrusions symmetrically arranged on both sides of the axis of the first rotating shaft 11, and the two sides of the protrusions along the circumferential direction of the first rotating shaft 11 respectively have inclined surfaces. As shown in Figure 13 and Figure 14 , two first protrusions 2101 are symmetrically arranged on the first gasket 210, and the two sides of the first protrusions 2101 are inclined surfaces. Two second protrusions 2091 are symmetrically arranged on the second gasket 209, and the two sides of the second protrusions 2091 are inclined surfaces. The symmetrically arranged protrusions can optimize the stress of the gasket, so that the gasket moves more smoothly along the axial direction of the first rotating shaft 11. It should be noted that the number and distribution of the protrusions on the gasket can be set in other forms as needed. It should be understood that in order to form an axial cam pair, the first cam 201 structure can also be arranged as a recess structure, and the second cam 204 structure is arranged as a protrusion structure.

[0077] As shown in Figure 18 , in the present embodiment, the entire movable part 207 moves in a direction parallel to the first rotating shaft 11, i.e., the movable part 207 as a whole undergoes translation, in order to improve the reliability of the movement of the movable part 207, as shown in Figure 11 , Figure 15 and Figure 16As shown, in the embodiment, a through hole is formed in the part between the first end and the second end of the movable member 207, and a guide column 2082 is arranged in the through hole. The guide column 2082 is arranged in parallel with the axis of the first rotating shaft 11. Specifically, the guide column 2082 can be fixedly arranged on the control module base 208. Preferably, the movable member 207 can be arranged in a plate shape, so as to minimize the size of the control module along the axial direction of the first rotating shaft 11. As shown, the first end of the movable member 207 can be arranged to cover the circular hole of the first rotating shaft 11. It should be understood that the through hole of the movable member 207, in which the guide column 2082 is arranged, can be a non-circular hole. Figure 16 As shown, in the embodiment, a through hole is formed in the part between the first end and the second end of the movable member 207, and a guide column 2082 is arranged in the through hole. The guide column 2082 is arranged in parallel with the axis of the first rotating shaft 11. Specifically, the guide column 2082 can be fixedly arranged on the control module base 208. Preferably, the movable member 207 can be arranged in a plate shape, so as to minimize the size of the control module along the axial direction of the first rotating shaft 11. As shown, the first end of the movable member 207 can be arranged to cover the circular hole of the first rotating shaft 11. It should be understood that the through hole of the movable member 207, in which the guide column 2082 is arranged, can be a non-circular hole.

[0078] As shown, in the embodiment, a through hole is formed in the part between the first end and the second end of the movable member 207, and a guide column 2082 is arranged in the through hole. The guide column 2082 is arranged in parallel with the axis of the first rotating shaft 11. Specifically, the guide column 2082 can be fixedly arranged on the control module base 208. Preferably, the movable member 207 can be arranged in a plate shape, so as to minimize the size of the control module along the axial direction of the first rotating shaft 11.

It should be understood that the through hole of the movable member 207, in which the guide column 2082 is arranged, can be a non-circular hole. Figure 5 As shown, in the embodiment, a through hole is formed in the part between the first end and the second end of the movable member 207, and a guide column 2082 is arranged in the through hole. The guide column 2082 is arranged in parallel with the axis of the first rotating shaft 11. Specifically, the guide column 2082 can be fixedly arranged on the control module base 208.

As shown, the first end of the movable member 207 can be arranged to cover the circular hole of the first rotating shaft 11. It should be understood that the through hole of the movable member 207, in which the guide column 2082 is arranged, can be a non-circular hole. Figure 17 As shown, in the embodiment, the limiting member 206 is assembled and connected with the second rotating shaft 12 through a non-circular hole. The limiting member 206 cannot rotate relative to the second rotating shaft 12. The circumferential surface of the limiting member 206 is provided with two blocking bodies which are misaligned along the circumferential direction and the axial direction of the second rotating shaft 12. During rotation of the second rotating shaft 12 as the rotating shaft, when the movable member 207 contacts the first limiting surface 2061 of the blocking body, the switching module forms one of the first state and the second state. That is, when the second rotating shaft 12 drives the limiting member 206 to rotate relative to the connecting assembly 2, the end of the movable member 207 close to the second rotating shaft 12, i.e., the second end of the movable member 207, moves along the circumferential direction of the second rotating shaft 12 relative to the limiting member 206. During the movement, the second end of the movable member 207 can meet the blocking body on the limiting member 206. After the first limiting surface 2061 of the blocking body contacts the movable member 207, the first limiting surface 2061 limits the movable member 207 from continuously moving along the circumferential direction of the second rotating shaft 12. At this time, the second clamping groove 2041 on the second cam 204 is opposite to the first clamping groove 2011 on the first cam 201, i.e., the switching module forms the first state or the second state described above. It should be understood that the misalignment distance of the two blocking bodies on the limiting member 206 along the circumferential direction of the second rotating shaft 12 should be able to allow the second end of the movable member 207 to pass through. The first limiting surface 2061 on one of the blocking bodies meets and contacts the second end of the movable member 207 during the forward rotation process of the hinge device (for example, the opening process of the first connecting member 31 and the second connecting member 32), and the first limiting surface 2061 on the other blocking body meets and contacts the second end of the movable member 207 during the reverse rotation process of the hinge device (for example, the closing process of the first connecting member 31 and the second connecting member 32). Specifically, the first limiting surface 2061 can be arranged to satisfy the parallel condition with the axis of the second rotating shaft 12. In the first state and the second state of the switching module, the movable member 207 can slide along the contacted first limiting surface 2061, i.e., the movable member 207 moves along the direction parallel to the second rotating shaft 12 against the first limiting surface 2061 of the blocking body.

[0079] As shown, in the embodiment, a through hole is formed in the part between the first end and the second end of the movable member 207, and a guide column 2082 is arranged in the through hole. The guide column 2082 is arranged in parallel with the axis of the first rotating shaft 11. Specifically, the guide column 2082 can be fixedly arranged on the control module base 208. Preferably, the movable member 207 can be arranged in a plate shape, so as to minimize the size of the control module along the axial direction of the first rotating shaft 11. As shown, the first end of the movable member 207 can be arranged to cover the circular hole of the first rotating shaft 11. It should be understood that the through hole of the movable member 207, in which the guide column 2082 is arranged, can be a non-circular hole. Figure 17As shown, in this embodiment, the end of the movable member 207 near the second rotating shaft 12 has an arc surface 2071 that fits against the surface of the limiting member 206, and the center of the arc surface 2071 is located on the axis of the second rotating shaft 12. That is, the second end of the movable member 207 abuts against the surface of the limiting member 206 through the arc surface 2071. In this way, when the second end of the movable member 207 moves relative to the limiting member 206 along the circumference of the second rotating shaft 12, the movement of the movable member 207 is smoother and more stable.

[0080] See Figures 1-4 , Figure 18 When the first connector 31 and the second connector 32 are in a 0° angle position, the slider 202 is coupled with the first cam 201 to restrict the rotation of the first rotating shaft 11 relative to the connecting assembly 2. Therefore, the second rotating shaft 12 acts as a rotation axis to provide rotation from a 0° angle position to a 120° angle position. The second cam 204 moves along... Figure 18 When rotated 120° clockwise, the second slot 2041 on the second cam 204 moves to a position opposite to the slider 202.

[0081] When the first connecting member 31 and the second connecting member 32 are in a 120° angle position, the end of the movable member 207 near the second rotating shaft 12 abuts against a stop of the limiting member 206, restricting the rotation of the second rotating shaft 12 relative to the connecting assembly 2. Therefore, the first rotating shaft 11, as a rotation axis, provides rotation from a 120° angle position to a 280° angle position, and the first cam 201 along... Figure 18 The first cam 201 rotates 160° counterclockwise, and the other first slot 2011 on the first cam 201 moves to a position opposite to the slider 202. During this rotation, the slider 202 moves along... Figure 18 The moving part 207 moves downwards, changing from coupling with the first cam 201 to coupling with the second cam 204. Figure 18 The movement to the left changes the restriction on the rotation of the second rotating shaft 12 relative to the connecting assembly 2 to the release of the restriction.

[0082] When the first connector 31 and the second connector 32 are in a 280° angle position, the restriction on the rotation of the second rotating shaft 12 relative to the connecting assembly 2 is released, and a space for movement is formed between the first cam 201 and the slider 202. Therefore, the second rotating shaft 12, as a rotation axis, provides rotation from a 280° angle position to a 360° angle position, and the second cam 204 continues along... Figure 18 The slider 202 rotates 80° clockwise. During this rotation, the slider 202 moves along... Figure 18 It moves upwards, changing from being coupled with the second cam 204 to being coupled with the first cam 201.

[0083] It should be understood that the process of rotating the first connecting member 31 and the second connecting member 32 from the 360° angle posture to the 0° angle posture is opposite to the above-mentioned rotating process, the movement of each part is in the reverse direction of the above-mentioned process, which will not be described here. It should be noted that, as shown in Figure 7 , the switching module base 203 is provided with a first stop block 2031 corresponding to the first cam 201 and a second stop block 2032 corresponding to the second cam 204. During the opening rotating process of the first connecting member 31 and the second connecting member 32, the first side of the first stop block 2031 abuts against the first cam 201 to limit the rotating of the first rotating shaft 11 relative to the connecting assembly 2 when the angle posture is 280°, as shown in Figure 3 , and the first side of the second stop block 2032 abuts against the second cam 204 to stop the opening action when the angle posture is 360°, as shown in Figure 4 . During the closing rotating process of the first connecting member 31 and the second connecting member 32, the second side of the first stop block 2031 abuts against the first cam 201 to limit the rotating of the first rotating shaft 11 relative to the connecting assembly 2 when the angle posture is 120°, as shown in Figure 2 , and the second side of the second stop block 2032 abuts against the second cam 204 to stop the closing action when the angle posture is 0°, as shown in Figure 1 .

[0084] Embodiment Two

[0085] Referring to Figures 19-21 , the difference between the embodiment two and the embodiment one of the present application mainly lies in the driving member. In the embodiment two, the hinge device comprises a strip-shaped first base hinged with the first rotating shaft 11 and the second rotating shaft 12, the driving member comprises a washer and an elastic member 211, the washer is located on one side of the movable member 207, and is axially slidably assembled on the first rotating shaft 11 through a non-circular hole. The elastic member 211 is connected with the movable member 207 and applies an action force to the movable member 207 along the axial direction of the first rotating shaft 11 and pointing to the washer. The first base is located on the side of the washer away from the movable member 207, and the side of the washer away from the movable member 207 is provided with a first cam 201 structure, and the side of the first base facing the movable member 207 is provided with a second cam 204 structure. The first cam 201 structure and the second cam 204 structure cooperate to form an axial cam pair.

[0086] In a preferred embodiment, the elastic member 211 and the washer are located on both sides of the movable member 207, compared with Figure 11 and Figure 20It can be seen that the difference between the second embodiment and the first embodiment is that one of the two pads, for example, the second pad 209, is replaced by the elastic member 211, and the two ends of the elastic member 211 abut against the movable member 207 and the control module base 208, so as to exert a force on the movable member 207 along the axial direction of the first rotating shaft 11 and pointing to the first pad 210. It should be understood that in the second embodiment, the control module base 208 no longer needs to be provided with the second groove 2081 described above. Specifically, the elastic member 211 can be provided as a wave spring.

[0087] The third embodiment

[0088] Referring to Figures 22-27 , the difference between the third embodiment and the first embodiment is mainly that the movable member 207 is hinged to the support base 2083 at a position between the first end and the second end of the movable member 207, and the hinge shaft 212 of the movable member 207 and the support base 2083 is arranged perpendicular to the axis of the first rotating shaft 11. As shown in Figure 22 、 Figure 24 and Figure 25 , the position between the first end and the second end of the movable member 207 is provided with a hinge hole through which the hinge shaft 212 is arranged, and the support base 2083 can be fixedly arranged on the control module base 208. As can be seen from Figure 27 , when the driving member, i.e., the first pad 210 and the second pad 209, drives the first end of the movable member 207 to move in a direction parallel to the first rotating shaft 11, the second end of the movable member 207 moves in the opposite direction. For example, during the rotation of the first connecting member 31 and the second connecting member 32 from a 120° angle posture to a 280° angle posture, the first end of the movable member 207 moves in the right direction in Figure 27 , and the second end of the movable member 207 moves in the left direction in Figure 27 .

[0089] It should be noted that in order to adapt to the movement of the second end of the movable member 207, the third embodiment makes adaptive adjustment to the structure of the limiting member 206 based on the first embodiment. As can be seen from Figure 17 and Figure 26 , the positions of the two blocking bodies on the limiting member 206 are different between the third embodiment and the first embodiment. It should be understood that the third embodiment can also use the same structure of the limiting member 206 as the first embodiment, but the pad structure in the first embodiment needs to be adjusted so that when the first connecting member 31 and the second connecting member 32 are in a 0° angle posture, the first end of the movable member 207 is tilted to the left side in Figure 27 relative to the second end. In addition, the third embodiment can use the same structure of the driving member as the second embodiment.
