Description
Technical Field
[0001] This invention relates to the field of power tool technology, and in particular to an anti-derailment suspension clamp for high-voltage cables. Background Technology
[0002] High-voltage transmission lines are an important part of the power system, responsible for transmitting electrical energy from the generation end to the load center over long distances; suspension clamps, as key hardware in transmission lines, are used to suspend cables on towers and bear the cable's own weight and dynamic wind loads.
[0003] Existing suspension clamps mostly adopt a bolt-tightening structure, relying on the preload of high-strength bolts to lock the pressure plate to the hull. Radial pressure is applied to the cable through a pad to provide axial friction, thereby fixing the cable within the clamp. However, under conditions of cable icing, galloping, and strong winds, the suspension clamp will continuously oscillate along the cable direction. This oscillation causes relative rotation of the hinge axis between the hanging plate and the hull. The clamping force of the existing structure only comes from the static preload of the bolts during installation, and the cable is prone to slipping out of the clamp under continuous oscillation conditions. Summary of the Invention
[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an anti-slip suspension clamp for high-voltage cables, which can reduce the risk of the cable slipping out of the clamp under continuous swinging conditions.

[0013] The linkage clamping assembly is connected to each of the drive assemblies and the suspension assembly respectively; when the clamp body swings to one side relative to the suspension assembly, the linkage clamping assembly drives the corresponding drive assembly to slide along the clamping direction, and the axial sliding gap provides displacement space for the sliding of the drive assembly.
[0014] Furthermore, the clamping assembly also has multiple translation guide rods, and each clamping member has at least two translation guide rods installed on opposite sides of the wire clamp body along the circumference, and the multiple translation guide rods located on the same side of the clamping member are arranged at intervals along the axial direction of the wire clamp body; each translation guide rod of the same clamping member extends radially along the wire clamp body.
[0015] The outer peripheral surface of the clamp body is provided with radial sliding guide holes corresponding to each of the translation guide rods.

Each translation guide rod is slidably inserted through the corresponding radial sliding guide hole, and one end of the translation guide rod extends through the corresponding radial sliding guide hole to the outer peripheral surface of the clamp body.
[0016] The end of the translation guide rod extending out of the outer peripheral surface of the clamp body is provided with an anti-detachment flange, which is used to abut against the outer peripheral surface of the clamp body.
[0017] Furthermore, the driving assembly includes a plurality of driving members, each of which is slidably mounted on the inner wall of the clamp body and is arranged in a one-to-one correspondence with each of the clamping members of the corresponding clamping assembly, so that the driving member can reciprocate relative to the corresponding clamping member along the axial direction of the clamp body.
[0018] The direction in which the driving member slides toward the corresponding end of the clamp body is the clamping direction, and the direction in which the driving member slides away from the corresponding end of the clamp body is the releasing direction.
[0019] The driving component is disposed between the inner wall of the clamp body and the corresponding clamping component; the driving component has a first driving inclined surface at one end facing the corresponding clamping component, and the first driving inclined surface extends obliquely along the axial direction of the clamp body; the clamping component has a second driving inclined surface at one end facing the corresponding driving component, and the second driving inclined surface extends obliquely along the axial direction of the clamp body; the first driving inclined surface and the corresponding second driving inclined surface slide in contact; when the driving component slides in the clamping direction, the first driving inclined surface slides relative to the second driving inclined surface to drive the corresponding clamping component to move radially along the clamp body and press the cable; when the driving component slides in the releasing direction, the first driving inclined surface slides relative to the second driving inclined surface to drive the clamping component to retract radially along the clamp body and release the cable.
[0020] The clamping member is also provided with two limiting shoulders, both of which are disposed on the second driving inclined surface and extend along the extension direction of the second driving inclined surface; the two limiting shoulders are disposed opposite to each other along the circumference of the clamp body, and the driving member slides and fits against the limiting shoulders on the corresponding sides along the circumference of the clamp body on the opposite sides respectively.
[0021] Furthermore, each of the wire clamp bodies is provided with a mounting portion at the position corresponding to each of the driving components. Each mounting portion is located on the inner wall of the wire clamp body and extends along the axial direction of the wire clamp body. Each mounting portion has a sliding groove on opposite sides of the wire clamp body in the circumferential direction. Each sliding groove passes through the corresponding mounting portion along the axial direction of the wire clamp body.
[0022] Each of the mounting portions is provided with the positioning structure, and the positioning structure has a plurality of positioning portions. The plurality of positioning portions are all disposed on the end of the mounting portion facing the corresponding driving member, and are arranged sequentially at intervals along the axial direction of the clamp body.
[0023] The driving component is provided with sliding limit blocks on both sides of the wire clamp body in the circumferential direction. Both sliding limit blocks extend along the axial direction of the wire clamp body and respectively extend into the corresponding groove on the corresponding side of the mounting part, and slide in cooperation with the corresponding groove.
[0024] Each of the driving components has multiple limiting grooves at one end facing the mounting portion. Among the cooperating driving components and the mounting portion, the number of limiting grooves on the driving component is less than the number of positioning portions on the mounting portion. When the driving component slides along the clamping direction, each of the limiting grooves on the driving component slides along the clamping direction with the driving component to disengage from the current positioning portion and engage with the next level positioning portion.
[0025] Furthermore, the inner wall of the limiting groove facing the loosening direction is a clamping limiting surface, and the inner wall of the limiting groove facing the clamping direction is an anti-loosening limiting surface; the distance between the clamping limiting surface and the anti-loosening limiting surface along the axial direction of the clamp body is greater than the width of the corresponding positioning part along the axial direction of the clamp body, so as to form the axial sliding gap; the anti-loosening limiting surface is used to abut against the corresponding positioning part when the driving member slides in the loosening direction under the action of the cable rebound force; the clamping limiting surface is used to abut against the corresponding positioning part when the linkage clamping assembly drives the corresponding driving component to slide along the clamping direction.
[0026] Furthermore, the clamping limiting surface extends obliquely along the depth direction corresponding to the limiting groove, and the lower end of the clamping limiting surface is disposed at the opening of the corresponding limiting groove, so as to guide the limiting groove to disengage from the current positioning part when the driving member continues to slide along the clamping direction.
[0027] The width of the groove along the radial direction of the clamp body is greater than the width of the sliding limit block along the radial direction of the clamp body, so as to form a radial clearance gap. The radial clearance gap is used to provide radial displacement space when the limit groove is disengaged from the current positioning part.
[0028] Furthermore, the outer peripheral surface of the clamp body is provided with a swing opening, which is located between the two clamping components and communicates with the cable passage; the outer peripheral surface of the clamp body is also provided with a hinge seat, which is located around the swing opening; the hinge seat is provided with a hinge through hole, which extends radially along the clamp body.
[0029] The suspension assembly includes a support plate, a first hinge shaft, and a second hinge shaft. The support plate has a first through hole and a second through hole at opposite ends. The first through hole extends radially along the clamp body and communicates with the hinge through hole. The first hinge shaft passes through the hinge through hole and the first through hole sequentially. The second through hole extends axially along the clamp body and communicates with the docking hole of the tower. The second hinge shaft passes through the interconnected second through hole and the docking hole of the tower.
[0030] The linkage clamping assembly includes a swinging force-applying component and two force-transmitting components. The swinging force-applying component has a connecting end and a force-applying end at opposite ends along the radial direction of the clamp body. The connecting end is mounted on the support plate, and the force-applying end extends into the cable passage through the swing opening, so that the swinging force-applying component swings relative to the clamp body with the support plate. The two force-transmitting components are slidably sleeved on the inner wall of the clamp body and are respectively arranged on opposite sides of the swinging force-applying component along the axial direction of the clamp body, and are respectively located between the swinging force-applying component and the corresponding drive assembly. When the clamp body swings relative to the support plate, the force-applying end of the swinging force-applying component pushes the corresponding force-transmitting component to slide along the clamping direction, thereby driving the corresponding drive assembly to slide along the clamping direction.
[0031] Furthermore, the linkage clamping assembly also includes multiple elastic abutment structures. Each of the force transmission components is equipped with multiple elastic abutment structures at one end facing the corresponding drive component, and the multiple elastic abutment structures on the force transmission component are arranged one-to-one with the multiple drive components of the corresponding drive component.
[0032] The elastic abutment structure includes a movable seat, an elastic element, and an abutment element; the movable seat is detachably mounted on the corresponding force transmission element; the movable seat has a movable groove at one end facing the corresponding drive element, and the movable groove extends along the axial direction of the clamp body; one end of the abutment element extends into the movable groove and slides with the movable groove, and the other end of the abutment element is used to abut against the corresponding drive element when the corresponding force transmission element slides in the clamping direction; the elastic element is housed in the movable groove, and one end of the elastic element abuts against the movable groove, and the other end of the elastic element abuts against the abutment element; the elastic element is used to provide the abutment element with an elastic force extending from the movable groove.
[0033] Furthermore, the inner wall of the clamp body is provided with at least two anti-deflection guide portions and a stroke limiting block; both anti-deflection guide portions extend along the axial direction of the clamp body and are arranged opposite to each other along the radial direction of the clamp body; the force transmission member is provided with a limiting guide groove corresponding to each anti-deflection guide portion, and each limiting guide groove passes through both ends of the force transmission member along the axial direction of the clamp body; each anti-deflection guide portion is slidably embedded in the corresponding limiting guide groove.
[0034] The travel limiting block is disposed between the two force transmission components and is located on the same axial section of the clamp body as the hinged through hole; the two opposite ends of the travel limiting block along the circumference of the clamp body are respectively used to abut against the force transmission components on the corresponding sides.
[0035] Furthermore, the travel limiting block is provided with magnetic attraction portions at both ends along the axial direction of the clamp body, and each force transmission component is provided with a magnetic attraction engagement portion on the side facing the travel limiting block; the magnetic attraction engagement portion is used to magnetically engage with the corresponding magnetic attraction portion when the corresponding force transmission component abuts against the travel limiting block.
[0036] Furthermore, the force-applying end of the swinging force-applying component is provided with two force-applying balls, which are arranged opposite each other along the radial direction of the clamp body and located in the same horizontal direction; the end of the force-transmitting component facing the swinging force-applying component is provided with a force-receiving groove corresponding to each force-applying ball, each force-receiving groove extends in the vertical direction, and the inner contour of the force-receiving groove is adapted to the outer contour of the force-applying ball; when the swinging force-applying component swings relative to the clamp body with the bearing plate, the force-applying ball is embedded in the corresponding force-receiving groove, and the outer peripheral surface of the force-applying ball slides against the inner wall of the force-receiving groove.
[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0038] The inner wall of the clamp body forms a cable passage; one end of the suspension assembly is hinged to the clamp body, and the other end is used to connect to the tower; thus providing space for the cable to pass through, and suspending the clamp body on the tower through the suspension assembly; at the same time, the clamp body can flexibly swing relative to the suspension assembly to alleviate the relative displacement of the cable under wind or ice load, which helps to reduce the risk of the cable slipping out of the clamp.
[0039] The clamping assembly is provided at both ends of the clamp body; each clamping assembly has multiple clamping members, which are spaced apart circumferentially within the cable passage of the clamp body and can extend and retract radially along the clamp body to clamp or release the cable; each clamping assembly is equipped with at least one driving assembly, and the driving assembly is kinetically connected to the corresponding clamping assembly; the driving assembly is mounted on the clamp body and can reciprocate axially along the clamp body to adjust the clamping members of the corresponding clamping assembly during sliding. The degree of extension and retraction allows the cable to be supported from multiple angles circumferentially when it is laid in the cable laying channel. At the same time, when the drive component slides along the axial direction, it converts the axial movement into the radial extension and retraction of the clamping component through the transmission connection. This allows the radial pressure of the clamping component on the cable to be adjusted according to the axial position of the drive component. This provides the corresponding clamping force according to the actual diameter of the cable and the working conditions, so as to avoid insufficient clamping force due to excessive gap between the clamping component and the cable. It also helps to avoid damage to the cable outer sheath due to excessive clamping of the cable by the clamping component.
[0040] Each of the aforementioned drive components has multiple limiting grooves, and these grooves on the same drive component are arranged at intervals along the axial direction of the clamp body. Multiple positioning structures are provided on the clamp body, and each drive component is equipped with at least one positioning structure. Each positioning structure has at least one positioning part, which is embedded in the limiting groove corresponding to the drive component. When the drive component slides, the positioning part is switchably embedded in one of the limiting grooves on the drive component. An axial sliding gap exists between the positioning part and the limiting groove. This allows for precise positioning of the drive components. When the component slides to different positions along the axial direction, the positioning part can be engaged with different limiting grooves to allow the drive component to switch between multiple axial positions and maintain the corresponding position. This helps the drive component to provide the corresponding degree of clamping force at different axial positions. At the same time, the axial sliding gap between the positioning part and the limiting groove allows the drive component to make a small displacement in the releasing direction under the action of the cable's elastic restoring force. This avoids the clamping part from exerting a continuous excessive clamping force on the cable, preventing damage to the cable sheath due to excessive clamping force. Thus, while ensuring clamping reliability, the risk of the cable slipping out of the clamp is reduced.
[0041] The linkage clamping assembly is connected to each of the drive assemblies and the suspension assembly respectively. When the clamp body swings to one side relative to the suspension assembly, the linkage clamping assembly drives the corresponding drive assembly to slide along the clamping direction. The axial sliding clearance provides displacement space for the sliding of the drive assembly. Thus, when the clamp body deflects relative to the suspension assembly due to cable swing, the linkage clamping assembly can transmit the mechanical motion generated by the swing to the drive assembly, driving the drive assembly located on one side of the swing direction to slide along the clamping direction. At the same time, the axial sliding clearance provides the necessary displacement space for the sliding of the drive assembly, preventing the drive assembly from being unable to be driven by the linkage clamping assembly due to a lack of relative movement margin between the positioning part and the limiting groove, ensuring that the drive assembly can be smoothly pushed when swing occurs. After the swing stops, the elasticity of the cable... The restoring force can drive the positioning part to slide in the loosening direction through the clamping component and the drive assembly, so that the positioning part abuts against the inner wall of the limiting groove. This restores the clamping force of the clamping component on the cable to the initial preload state, preventing the clamping component from continuing to squeeze the cable with a large clamping force after the swing stops, and reducing the possibility of damage to the cable sheath due to excessive pressure over a long period of time. When the swing amplitude increases to the point that the driving force of the linkage clamping component on the drive assembly is sufficient to overcome the matching resistance between the positioning part and the current limiting groove, the positioning part can disengage from the current limiting groove and embed into the next level limiting groove. This allows the drive assembly to stabilize in a new axial position after the swing stops, thereby increasing the basic preload of the drive assembly. This enables the clamping component to clamp the cable with a higher initial clamping force in subsequent swing conditions, further reducing the risk of the cable slipping out of the clamp under continuous swing conditions.

Detailed Implementation
[0049] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0050] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.
[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0052] See Figures 1-3 The specific implementation of a preferred embodiment of the present invention is as follows: A suspension clamp for high voltage cables includes: a clamp body 1, a suspension assembly 2, at least two clamping assemblies 3, multiple driving assemblies 4, multiple positioning structures 5, and a linkage clamping assembly 7.
[0053] The inner wall of the clamp body 1 forms a cable passage channel 11; one end of the suspension component 2 is hinged to the clamp body 1, and the other end is used to connect to the pole; both ends of the clamp body 1 are provided with clamping components 3; each clamping component 3 has multiple clamping members 31, each clamping member 31 is arranged at intervals along the circumference of the clamp body 1 in the cable passage channel 11, and can extend and retract along the radial direction of the clamp body 1 to clamp or release the cable 8; each clamping component 3 is equipped with at least one driving component 4, and the driving component 4 is pulsatorically connected to the corresponding clamping component 3; the driving component 4 is assembled on the clamp body 1 and can slide back and forth along the axial direction of the clamp body 1 to adjust the extension and retraction degree of each clamping member 31 of the corresponding clamping component 3 during sliding; each driving component 4 has multiple limiting grooves 41, and the multiple limiting grooves 41 provided on the same driving component 4 are arranged at intervals along the axial direction of the clamp body 1.
[0054] Multiple positioning structures 5 are disposed on the clamp body 1, and each drive assembly 4 is equipped with at least one positioning structure 5; the positioning structure 5 has at least one positioning part 51, which is embedded in the limiting groove 41 corresponding to the drive assembly 4; when the drive assembly 4 slides, the positioning part 51 is switchably embedded in one of the limiting grooves 41 on the drive assembly 4; there is an axial sliding gap 6 between the positioning part 51 and the limiting groove 41.
[0055] The linkage clamping assembly 7 is connected to each of the driving assemblies 4 and the suspension assembly 2 respectively; when the clamp body 1 swings to one side relative to the suspension assembly 2, the linkage clamping assembly 7 drives the corresponding driving assembly 4 to slide along the clamping direction, and the axial sliding gap 6 provides displacement space for the sliding of the driving assembly 4.
[0056] In use, the cable 8 is threaded through the cable threading channel 11, and then the drive member 42 is pushed to slide along the clamping direction. The drive member 42 drives each clamping member 31 to move radially, so that each clamping member 31 fits against the outer circumferential surface of the cable 8, and each clamping member 31 applies an initial pre-tightening force to the cable 8. During the pushing process, the positioning part 51 disengages from the current limiting groove 41 and embeds into the adjacent next-level limiting groove 41, so that the axial position of the drive member 42 changes step by step and remains stable in the axial position. When the operator releases the push, the elastic restoring force of the cable 8 pushes each clamping member 31 to move radially, and drives the drive member 42 to slide along the releasing direction through the transmission connection until the positioning part 51 abuts against the inner wall of the current limiting groove 41.
[0057] When the cable 8 swings due to wind or ice load, the clamp body 1 deflects relative to the suspension assembly 2 along with the cable 8. Under the relative swinging action between the clamp body 1 and the suspension assembly 2, the linkage clamping assembly 7 transmits the mechanical motion generated by the swing to the drive assembly 4 located on one side of the swing direction. Due to the existence of the axial sliding gap, the drive assembly 4 can slide along the clamping direction under the action of the linkage clamping assembly 7. When the drive assembly 4 slides along the clamping direction, it drives the clamping members 31 of the corresponding clamping assembly 3 to move radially, so that the clamping force of the clamping members 31 on the cable 8 increases accordingly with the increase of the swing amplitude.
[0058] When the swing stops, the elastic restoring force of the cable 8 pushes each clamping member 31 to move radially, and drives the driving member 42 to slide in the loosening direction through the transmission connection until the positioning part 51 abuts against the inner wall of the current limiting groove 41.
[0059] When the swing amplitude of the cable 8 increases to the point that the driving force of the linkage clamping assembly 7 on the drive assembly 4 is sufficient to overcome the cooperation resistance between the positioning part 51 and the current limiting groove 41, the positioning part 51 disengages from the current limiting groove 41 and embeds into the adjacent next-level limiting groove 41, so that the drive assembly 4 remains stable in the new axial position, and the basic pre-tightening force of each clamping member 31 on the cable 8 is correspondingly increased.
[0060] Obviously, the inner wall of the clamp body 1 forms a cable passage 11; one end of the suspension assembly 2 is hinged to the clamp body 1, and the other end is used to connect to the tower; thus providing space for the cable 8 to pass through, and suspending the clamp body 1 on the tower through the suspension assembly 2; at the same time, the clamp body 1 can flexibly swing relative to the suspension assembly 2 to alleviate the relative displacement of the cable 8 under wind or ice load, which helps to reduce the risk of the cable 8 slipping out of the clamp; the clamping assembly 3 is provided at both ends of the clamp body 1; the clamping assembly 3 has multiple clamping members 31, each clamping member 31 is arranged circumferentially within the cable passage 11 of the clamp body 1, and can extend and retract radially along the clamp body 1 to clamp or release the cable 8; each clamping assembly 3 is equipped with at least one driving assembly 4, and the driving assembly 4 is equipped with at least one driving assembly 4. The driving component 4 is connected to the corresponding clamping component 3 via a transmission connection. The driving component 4 is mounted on the clamp body 1 and can slide back and forth along the axial direction of the clamp body 1 to adjust the extension and retraction of each clamping member 31 of the corresponding clamping component 3 during sliding. Thus, when the cable 8 is passed through the cable passage 11, multiple clamping members 31 can provide multi-angle support to the cable 8 from the circumferential direction. At the same time, when the driving component 4 slides along the axial direction, the axial movement is converted into the radial extension and retraction of the clamping member 31 through the transmission connection, so that the radial pressure of the clamping member 31 on the cable 8 can be adjusted with the change of the axial position of the driving component 4. This allows the corresponding clamping force to be provided according to the actual diameter of the cable 8 and the working conditions, so as to avoid insufficient clamping force due to excessive gap between the clamping member 31 and the cable 8, and also to avoid damage to the outer sheath of the cable 8 due to excessive pressure of the clamping member 31 on the cable 8.
[0061] Each of the driving components 4 has multiple limiting grooves 41, and the multiple limiting grooves 41 provided on the same driving component 4 are arranged at intervals along the axial direction of the clamp body 1; multiple positioning structures 5 are provided on the clamp body 1, and each driving component 4 is equipped with at least one positioning structure 5; the positioning structure 5 has at least one positioning part 51, and the positioning part 51 is embedded in the limiting groove 41 corresponding to the driving component 4; when the driving component 4 slides, the positioning part 51 is switchably embedded in one of the limiting grooves 41 on the driving component 4; there is an axial sliding gap 6 between the positioning part 51 and the limiting groove 41; from When the drive assembly 4 slides to different positions along the axial direction, the positioning part 51 can be engaged with different limiting grooves 41 to allow the drive assembly 4 to switch between multiple axial positions and maintain the corresponding position. This helps the drive assembly 4 to provide the corresponding degree of clamping force at different axial positions. At the same time, the axial sliding gap 6 between the positioning part 51 and the limiting groove 41 allows the drive assembly 4 to make a small displacement in the loosening direction under the action of the elastic restoring force of the cable 8, so as to avoid the clamping part 31 from exerting a continuous excessive clamping force on the cable 8, and prevent the outer sheath of the cable 8 from being damaged due to excessive clamping force. This reduces the risk of the cable 8 slipping out of the clamp while ensuring the reliability of clamping.
[0062] The linkage clamping assembly 7 is connected to each of the drive assemblies 4 and the suspension assembly 2 respectively. When the clamp body 1 swings to one side relative to the suspension assembly 2, the linkage clamping assembly 7 drives the corresponding drive assembly 4 to slide along the clamping direction. The axial sliding gap 6 provides displacement space for the sliding of the drive assembly 4. Thus, when the clamp body 1 deflects relative to the suspension assembly 2 due to the swing of the cable 8, the linkage clamping assembly 7 can transmit the mechanical motion generated by the swing to the drive assembly 4, driving the drive assembly 4 located on one side of the swing direction to slide along the clamping direction. At the same time, the axial sliding gap 6 provides the necessary displacement space for the sliding of the drive assembly 4, avoiding the drive assembly 4 from being unable to be driven by the linkage clamping assembly 7 due to the lack of relative movement margin between the positioning part 51 and the limiting groove 41, ensuring that the drive assembly 4 can be smoothly pushed when the swing occurs. After the swing stops, the elastic restoring force of the cable 8 can... The clamping member 31 and the driving assembly 4 can drive the positioning part 51 to slide in the loosening direction, so that the positioning part 51 abuts against the inner wall of the limiting groove 41, thereby restoring the clamping force of the clamping member 31 on the cable 8 to the initial pre-tightening force state, avoiding the clamping member 31 from continuing to squeeze the cable 8 with a large clamping force after the swing stops, reducing the possibility of the cable 8's outer sheath being damaged due to excessive pressure over a long period of time; when the swing amplitude increases to the point that the driving force of the linkage clamping assembly 7 on the driving assembly 4 is sufficient to overcome the cooperation resistance between the positioning part 51 and the current limiting groove 41, the positioning part 51 can disengage from the current limiting groove 41 and embed into the next level limiting groove 41, so that the driving assembly 4 stabilizes in a new axial position after the swing stops, thereby increasing the basic pre-tightening force of the driving assembly 4, enabling the clamping member 31 to clamp the cable 8 with a higher initial clamping force in subsequent swing conditions, further reducing the risk of the cable 8 slipping out of the clamp under continuous swing conditions.
[0063] See Figures 1-4 In this embodiment, in order to more effectively reduce the risk of the cable 8 slipping out of the clamp under continuous swinging conditions, preferably, the clamping assembly 3 also has multiple translation guide rods 32. Each clamping member 31 is equipped with at least two translation guide rods 32 on opposite sides of the clamp body 1 in the circumferential direction, and multiple translation guide rods 32 located on the same side of the clamping member 31 are arranged at intervals along the axial direction of the clamp body 1; each translation guide rod 32 of the same clamping member 31 extends radially along the clamp body 1.
[0064] The outer peripheral surface of the clamp body 1 is provided with radial sliding guide holes 12 corresponding to each of the translation guide rods 32. Each radial sliding guide hole 12 extends radially along the clamp body 1 and is connected to the cable passage channel 11. Each translation guide rod 32 is slidably inserted into the corresponding radial sliding guide hole 12, and one end of the translation guide rod 32 extends out to the outer peripheral surface of the clamp body 1 through the corresponding radial sliding guide hole 12.
[0065] The translation guide rod 32 has an anti-detachment flange 321 at one end extending from the outer peripheral surface of the clamp body 1. The anti-detachment flange 321 is used to abut against the outer peripheral surface of the clamp body 1.
[0066] Each of the translational guide rods 32 passes through the corresponding radial sliding guide holes 12, providing an independent guide path for the radial extension and retraction of each clamping member 31. This ensures that each clamping member 31 maintains a stable direction of movement during radial displacement, reducing jamming caused by skewness during extension and retraction. Simultaneously, multiple translational guide rods 32 located on the same side of the clamping member 31 are spaced apart along the axial direction of the clamp body 1, constraining the radial movement of the clamping member 31 from multiple positions, thus improving the stability of the clamping member 31's movement during radial extension and retraction. Furthermore, by providing anti-detachment flanges 321 on the translational guide rods 32, the displacement amplitude of the translational guide rods 32 towards the cable passage 11 is limited, preventing the clamping member 31 from detaching from the clamp body 1 due to excessive retraction of the translational guide rods 32 when releasing the cable 8, ensuring the reliability of the clamping member 31's movement during radial extension and retraction.
[0067] See Figures 2-4 Furthermore, the driving assembly 4 includes a plurality of driving members 42, each of which can be slidably mounted on the inner wall of the clamp body 1 and is arranged in a one-to-one correspondence with each of the clamping members 31 of the clamping assembly 3, so that the driving member 42 can slide back and forth along the axial direction of the clamp body 1 relative to the corresponding clamping member 31.
[0068] The direction in which the driving member 42 slides toward the corresponding end of the wire clamp body 1 is the clamping direction, and the direction in which the driving member 42 slides away from the corresponding end of the wire clamp body 1 is the releasing direction.
[0069] The driving member 42 is disposed between the inner wall of the clamp body 1 and the corresponding clamping member 31; the driving member 42 has a first driving inclined surface 421 at one end facing the corresponding clamping member 31, and the first driving inclined surface 421 extends obliquely along the axial direction of the clamp body 1; the clamping member 31 has a second driving inclined surface 311 at one end facing the corresponding driving member 42, and the second driving inclined surface 311 extends obliquely along the axial direction of the clamp body 1; the first driving inclined surface 421 and the corresponding second driving inclined surface 311 are slidably engaged; when the driving member 42 slides in the clamping direction, the first driving inclined surface 421 slides relative to the second driving inclined surface 311 to drive the corresponding clamping member 31 to move radially along the clamp body 1 and press the cable 8; when the driving member 42 slides in the releasing direction, the first driving inclined surface 421 slides relative to the second driving inclined surface 311 to drive the clamping member 31 to retract radially along the clamp body 1 and release the cable 8.
[0070] The clamping member 31 is also provided with two limiting shoulders 312. Both limiting shoulders 312 are disposed on the second driving inclined surface 311 and extend along the extension direction of the second driving inclined surface 311. The two limiting shoulders 312 are disposed opposite to each other along the circumference of the clamp body 1. The driving member 42 slides and fits against the limiting shoulders 312 on the corresponding sides along the circumference of the clamp body 1.
[0071] By configuring each driving component 42 in a one-to-one correspondence with a corresponding clamping component 31, the radial extension and retraction of each clamping component 31 is independently driven by its corresponding driving component 42. This facilitates independent adjustment of the radial position of each clamping component 31 according to the actual shape of the outer circumference of the cable 8, allowing each clamping component 31 to fit more evenly against the outer circumference of the cable 8. The sliding contact between the first driving inclined surface 421 and the second driving inclined surface 311 converts the axial reciprocating sliding of the driving component 42 into the radial extension and retraction of the clamping component 31, ensuring that the axial displacement of the driving component 42 and the radial displacement of the clamping component 31 are... The established correspondence between the drive member 42 and the clamping member 31 allows for adjustment of the clamping force of the clamping member 31 on the cable 8 by controlling the axial position of the drive member 42. The setting of the limiting shoulder 312 can circumferentially limit the relative movement between the drive member 42 and the clamping member 31, preventing the drive member 42 from shifting relative to the clamping member 31 during the sliding process, which would cause a change in the contact state between the first driving inclined surface 421 and the second driving inclined surface 311. This helps to ensure the stability of the motion transmission between the drive member 42 and the clamping member 31, thereby helping to reduce the risk of the cable 8 slipping out of the clamp under continuous swinging conditions.
[0072] See Figure 1 , Figure 2 and Figure 4Furthermore, each of the wire clamp bodies 1 is provided with a mounting portion 13 at the position corresponding to each of the driving components 42. Each mounting portion 13 is provided on the inner wall of the wire clamp body 1 and extends along the axial direction of the wire clamp body 1. Each mounting portion 13 is provided with a sliding groove 14 on opposite sides of the wire clamp body 1 in the circumferential direction. Each sliding groove 14 passes through the corresponding mounting portion 13 along the axial direction of the wire clamp body 1.
[0073] Each of the mounting portions 13 is provided with the positioning structure 5, and the positioning structure 5 has a plurality of positioning portions 51. The plurality of positioning portions 51 are all disposed on one end of the mounting portion 13 facing the driving member 42, and are arranged sequentially at intervals along the axial direction of the clamp body 1.
[0074] The driving component 42 is provided with sliding limit blocks 422 on both sides of the wire clamp body 1 around the circumference. Both sliding limit blocks 422 extend along the axial direction of the wire clamp body 1 and respectively extend into the corresponding groove 14 on the corresponding side of the mounting part 13, and slide in cooperation with the corresponding groove 14.
[0075] Each of the driving members 42 has multiple limiting grooves 41 at one end facing the mounting part 13. Among the driving members 42 and the mounting part 13 that cooperate with each other, the number of limiting grooves 41 on the driving member 42 is less than the number of positioning parts 51 on the mounting part 13. When the driving member 42 slides along the clamping direction, each of the limiting grooves 41 on the driving member 42 slides along the clamping direction with the driving member 42 to disengage from the current positioning part 51 and engage with the next level positioning part 51.
[0076] The sliding grooves 14 on both sides of the mounting part 13 slide and engage with the sliding limit blocks 422 on both sides of the driving member 42, guiding and limiting the sliding direction of the driving member 42. This ensures that the driving member 42 maintains a stable motion trajectory during axial reciprocating sliding and reduces the deviation of the driving member 42 caused by uneven force during sliding. Multiple positioning parts 51 are arranged sequentially at intervals along the axial direction of the mounting part 13. In conjunction with the multiple limit grooves 41 on the driving member 42, when the driving member 42 slides in the clamping direction, the limit grooves 41 can disengage from the current positioning part 51 and engage. The next-level positioning part 51 enables step-by-step adjustment of the axial position of the drive component 42, allowing the drive component 42 to switch between multiple preset axial positions and maintain stability. Simultaneously, the number of upper limit grooves 41 on the drive component 42 is less than the number of positioning parts 51 on the mounting part 13. This ensures that even when the drive component 42 slides to a position close to the end of the mounting part 13, there are still positioning parts 51 available for the limit grooves 41 to engage, guaranteeing effective positioning of the drive component 42 throughout its entire stroke range. This allows the drive component 42 to provide corresponding clamping forces at different axial positions. Furthermore, due to the design of the slide groove 14 extending axially through the mounting part 13, the sliding limit blocks 422 on both sides of the drive component 42 can engage with the slide groove 14 from the port of the clamp body 1, simplifying the assembly operation between the drive component 42 and the mounting part 13 and reducing assembly difficulty.
[0077] See Figure 3 Furthermore, the inner wall of the limiting groove 41 facing the loosening direction is a clamping limiting surface 411, and the inner wall of the limiting groove 41 facing the clamping direction is an anti-loosening limiting surface 412; the distance between the clamping limiting surface 411 and the anti-loosening limiting surface 412 along the axial direction of the clamp body 1 is greater than the width of the corresponding positioning part 51 along the axial direction of the clamp body 1, so as to form the axial sliding gap 6; the anti-loosening limiting surface 412 is used to abut against the corresponding positioning part 51 when the driving member 42 slides in the loosening direction under the action of the rebound force of the cable 8; the clamping limiting surface 411 is used to abut against the corresponding positioning part 51 when the linkage clamping assembly 7 drives the corresponding driving assembly 4 to slide in the clamping direction.
[0078] By designing the distance between the clamping limiting surface 411 and the anti-loosening limiting surface 412 to be greater than the axial width of the positioning part 51, an axial sliding gap 6 is formed between the positioning part 51 and the limiting groove 41, providing a certain range of free movement for the positioning part 51 within the limiting groove 41. This prevents the driving part 42 from being unable to be pushed due to the lack of relative movement space between the positioning part 51 and the limiting groove 41. When the driving part 42 slides in the loosening direction under the action of the rebound force of the cable 8, the anti-loosening limiting surface 412 abuts against the corresponding positioning part 51, so as to maintain the basic clamping force of the clamping part 31 on the cable 8 without damaging the outer sheath of the cable 8, thereby reducing the risk of the cable 8 being damaged and slipping due to excessive clamping force under continuous swinging conditions.
[0079] See Figure 3 and Figure 4 Furthermore, the clamping limiting surface 411 extends obliquely along the depth direction corresponding to the limiting groove 41, and the lower end of the clamping limiting surface 411 is disposed at the groove opening corresponding to the limiting groove 41, so as to guide the limiting groove 41 to disengage from the current positioning part 51 when the driving member 42 continues to slide along the clamping direction.
[0080] The width of the groove 14 along the radial direction of the clamp body 1 is greater than the width of the sliding limit block 422 along the radial direction of the clamp body 1, so as to form a radial clearance gap 141. The radial clearance gap 141 is used to provide radial displacement space for the limit groove 41 to disengage from the current positioning part 51.
[0081] By extending the clamping limiting surface 411 at an inclination along the depth direction of the limiting groove 41, the positioning part 51 can gradually move towards the groove opening along the inclination direction of the clamping limiting surface 411 when the driving member 42 slides in the clamping direction. This reduces the resistance that the positioning part 51 needs to overcome when it disengages from the current limiting groove 41, allowing the limiting groove 41 to disengage from the current positioning part 51 more smoothly under the continuous pushing of the driving member 42. The radial clearance gap 141 formed between the sliding groove 14 and the sliding limiting block 422 is used when the limiting groove 41 disengages from the current positioning part. During the process of 51, the drive component 42 is provided with radial displacement space, so that the drive component 42 can generate corresponding radial clearance at the moment when the positioning part 51 is disengaged from the limiting groove 41. This avoids rigid interference between the positioning part 51 and the limiting groove 41 due to the lack of radial movement margin of the drive component 42, thereby ensuring that the drive component 42 can switch smoothly between multiple levels of limiting grooves 41. This ensures that the step-by-step embedding and cooperation between the positioning part 51 and the limiting groove 41 can continue, which helps to reduce the risk of the cable 8 slipping out of the clamp under continuous swing conditions.
[0082] See Figure 1 , Figure 2 and Figure 6 Furthermore, the outer peripheral surface of the clamp body 1 is provided with a swing opening 15, which is located between the two clamping components 3 and communicates with the cable passage channel 11; the outer peripheral surface of the clamp body 1 is also provided with a hinge seat 16, which is located around the swing opening 15; the hinge seat 16 is provided with a hinge through hole 161, which extends radially along the clamp body 1.
[0083] The suspension assembly 2 includes a support plate 21, a first hinge shaft 22, and a second hinge shaft 23. The support plate 21 has a first through hole 211 and a second through hole 212 at opposite ends. The first through hole 211 extends radially along the clamp body 1 and communicates with the hinge through hole 161. The first hinge shaft 22 passes through the hinge through hole 161 and the first through hole 211 sequentially. The second through hole 212 extends axially along the clamp body 1 and communicates with the docking hole of the tower. The second hinge shaft 23 passes through the interconnected second through hole 212 and the docking hole of the tower.
[0084] The linkage clamping assembly 7 includes a swinging force-applying component 71 and two force-transmitting components 72. The swinging force-applying component 71 has a connecting end 711 and a force-applying end 712 at opposite ends along the radial direction of the clamp body 1. The connecting end 711 is mounted on the support plate 21, and the force-applying end 712 extends into the cable passage channel 11 through the swing opening 15, so that the swinging force-applying component 71 swings relative to the clamp body 1 with the support plate 21. The two force-transmitting components 72 are slidably sleeved on the inner wall of the clamp body 1 and are respectively arranged on opposite sides of the swinging force-applying component 71 along the axial direction of the clamp body 1, and are respectively located between the swinging force-applying component 71 and the corresponding drive assembly 4. When the clamp body 1 swings relative to the support plate 21, the force-applying end 712 of the swinging force-applying component 71 pushes the corresponding force-transmitting component 72 to slide along the clamping direction, so as to drive the corresponding drive assembly 4 to slide along the clamping direction.
[0085] The swing opening 15 provides clearance for the force-applying end 712 of the swing force-applying member 71 to extend into the cable passage 11. The bearing plate 21 is hinged to the hinge seat 16 via the first hinge shaft 22, allowing the clamp body 1 to swing relative to the bearing plate 21, thus achieving a compliant response of the clamp body 1 to the swing motion of the cable 8. The connecting end 711 of the swing force-applying member 71 is mounted on the bearing plate 21, and the force-applying end 712 extends into the cable passage 11 through the swing opening 15, allowing the swing force-applying member 71 to swing relative to the clamp body 1 with the bearing plate 21. When the clamp body 1 swings to one side relative to the bearing plate 21, the force-applying end 712 of the swing force-applying member 71 deflects to the corresponding side and pushes the force transmission member 72 on the corresponding side, which in turn pushes the corresponding force transmission member 72. The drive assembly 4 on the side slides along the clamping direction, transmitting the swing motion of the clamp body 1 relative to the bearing plate 21 into the sliding motion of the drive assembly 4 along the clamping direction, thereby converting the mechanical energy generated by the swing of the cable 8 into the clamping force of the clamping member 31; and the greater the swing amplitude of the clamp body 1 relative to the bearing plate 21, the greater the displacement of the force-applying end 712 of the swing force-applying member 71 to the corresponding side, the farther the force-transmitting member 72 and the drive assembly 4 slide along the clamping direction, and the greater the degree of radial contraction of the drive assembly 4 driving the clamping member 31 through the transmission connection, so that the clamping force of the clamping member 31 on the cable 8 increases with the increase of the swing amplitude, realizing the dynamic adjustment of the clamping force according to the swing state, which helps to reduce the risk of the cable 8 slipping out of the clamp under continuous swing conditions.
[0086] See Figure 5 and Figure 6 Furthermore, the linkage clamping assembly 7 also includes a plurality of elastic abutment structures 73. Each of the force transmission components 72 is provided with a plurality of elastic abutment structures 73 at one end facing the corresponding drive assembly 4, and the plurality of elastic abutment structures 73 on the force transmission component 72 are arranged in a one-to-one correspondence with the plurality of drive components 42 of the corresponding drive assembly 4.
[0087] The elastic abutment structure 73 includes a movable seat 731, an elastic element 732, and an abutment element 733; the movable seat 731 is detachably mounted on the force transmission element 72; the movable seat 731 has a movable groove 7311 at one end facing the driving element 42, and the movable groove 7311 extends along the axial direction of the clamp body 1; one end of the abutment element 733 extends into the movable groove 7311 and slides with the movable groove 7311. The other end of the abutment 733 is used to abut against the corresponding drive member 42 when the corresponding force transmission member 72 slides in the clamping direction; the elastic member 732 is housed in the supply groove 7311, and one end of the elastic member 732 abuts against the supply groove 7311, and the other end of the elastic member 732 abuts against the abutment 733; the elastic member 732 is used to provide the abutment 733 with an elastic force extending from the supply groove 7311.
[0088] The elastic abutment structure 73 is disposed between the force transmission member 72 and the driving member 42. When the force transmission member 72 slides along the clamping direction, the abutment member 733 first contacts the corresponding driving member 42 and pushes the driving member 42 to slide along the clamping direction, so that the movement of the force transmission member 72 can be transmitted to the driving member 42 through the elastic abutment structure 73. The elastic member 732 is housed in the movable groove 7311 and abuts against the abutment member 733. When the abutment member 733 is subjected to the reaction force of the driving member 42, it can generate compression deformation, which is beneficial to absorb the rigid impact between the force transmission member 72 and the driving member 42. At the same time, during the swinging process, the elastic abutment structure 73 can also absorb part of the impact energy generated when the clamp body 1 swings with the cable 8 through the compression deformation of the elastic member 732, which is beneficial to reduce the impact load on the stability of the fit between the driving member 42 and the positioning structure 5.
[0089] Furthermore, when the swing amplitude of the line clamp body 1 is large and the clamping force of the clamping member 31 on the cable 8 increases to the point that the driving member 42 can no longer slide along the clamping direction, the abutment member 733 can overcome the elastic force of the elastic member 732 under the reaction force of the driving member 42 and retract into the movable groove 7311. This allows the force transmission member 72 to continue sliding a certain distance along the clamping direction after the driving member 42 stops moving, preventing the force transmission member 72 from being damaged by excessive reaction force due to the jamming of the driving member 42. Moreover, the closer the driving member 42 is to the force transmission member 72, that is, the closer the position of the driving member 42 along the axial direction of the line clamp body 1 towards the side where the force transmission member 72 is located, the smaller the clamping degree of the driving member 42 on the clamping member 31. At this time, the abutment member 733 can retract into the movable groove 7311 under the reaction force of the driving member 42. Under the elastic force of the elastic element 732, it remains extended and continuously abuts against the drive element 42. This allows the elastic abutment structure 73 to directly push the drive element 42 to slide along the clamping direction without overcoming the empty stroke when the next swing occurs. This improves the response speed of the linkage clamping assembly 7 to the driving action of the drive element 42. Furthermore, the elastic force applied by the elastic element 732 to the drive element 42 through the abutment element 733 is in the clamping direction. The drive element 42 can move along the clamping direction under the push of the abutment element 733, reducing the tendency of the drive element 42 to slide in the loosening direction due to the elastic restoring force of the cable 8 itself. This helps to enhance the clamping force of the clamping element 31 on the cable 8 in a timely manner under the continuous swinging condition of the cable 8, thereby reducing the risk of the cable 8 slipping out of the clamp.
[0090] The elastic element 732 is preferably a spring; the movable seat 731 is detachably mounted on the force transmission element 72 via a pre-set lug and threaded fastener.
[0091] See Figure 2 and Figure 6 Furthermore, the inner wall of the clamp body 1 is provided with at least two anti-deflection guide portions 17 and a travel limiting block 18; both anti-deflection guide portions 17 extend along the axial direction of the clamp body 1 and are arranged opposite to each other along the radial direction of the clamp body 1; the force transmission member 72 is provided with a limiting guide groove 721 corresponding to each anti-deflection guide portion 17, and each limiting guide groove 721 passes through both ends of the force transmission member 72 along the axial direction of the clamp body 1; each anti-deflection guide portion 17 is slidably embedded in the corresponding limiting guide groove 721.
[0092] The stroke limiting block 18 is disposed between the two force transmission components 72 and is located on the same axial section of the clamp body 1 as the hinge through hole 161; the two opposite ends of the stroke limiting block 18 along the circumference of the clamp body 1 are respectively used to abut against the corresponding force transmission components 72.
[0093] Two anti-deflection guides 17 are arranged radially opposite to each other along the clamp body 1, so that the two anti-deflection guides 17 are respectively embedded in the limiting guide grooves 721 of the two force transmission members 72. When the force transmission member 72 slides along the axial direction of the clamp body 1, each anti-deflection guide 17 can constrain the sliding direction of the corresponding force transmission member 72, which helps to limit the force transmission member 72 from deflecting around its own axis during the sliding process. By setting the stroke limit block 18 between the two force transmission members 72, when the undriven force transmission member 72 tends to slide to the other side due to the tilt of the clamp body 1, the force transmission member 72 is blocked on the side where it is located, reducing the situation where the force transmission member 72 slides to the other side due to gravity or tilt and interferes with the reset movement of the swing force application member 71. This helps to ensure that the linkage clamping assembly 7 can be reset normally after each swing, so that the clamping force of the clamping member 31 on the cable 8 can be restored according to the swing state, which helps to reduce the risk of the cable 8 slipping out of the clamp under continuous swing conditions.
[0094] See Figure 5 and Figure 6 Furthermore, the travel limiting block 18 is provided with magnetic attraction portions 181 at both ends along the axial direction of the clamp body 1, and each force transmission member 72 is provided with a magnetic attraction engagement portion 722 on the side facing the travel limiting block 18; the magnetic attraction engagement portion 722 is used to magnetically engage with the corresponding magnetic attraction portion 181 when the corresponding force transmission member 72 abuts against the travel limiting block 18.
[0095] In the initial state, the magnetic attraction between the magnetic engagement part 722 and the magnetic attraction part 181 keeps the force transmission member 72 in the position of abutting the travel limit block 18. When the clamp body 1 swings relative to the support plate 21, the force application end 712 of the swing force application member 71 pushes the corresponding force transmission member 72 to slide in the clamping direction. This driving force can overcome the magnetic attraction between the magnetic engagement part 722 and the magnetic attraction part 181, causing the force transmission member 72 to disengage from the travel limit block 18 and slide in the clamping direction. After the swing ends, the elastic member 732 of the elastic abutment structure 73 releases the force. The elastic force pushes the abutment 733, which in turn pushes the drive 42 and the force transmission member 72 to slide in the release direction, causing the force transmission member 72 to move toward the travel limit block 18 and abut against it. At this time, the magnetic attraction between the magnetic attraction part 722 and the magnetic attraction part 181 helps to maintain the abutment state between the force transmission member 72 and the travel limit block 18, so that the force transmission member 72 can be kept relatively stably in the limit position in the release direction before the next swing cycle arrives, so as to ensure that it can be smoothly driven by the swing force application member 71 when the next swing occurs.
[0096] The magnetic attraction part 181 is preferably a ferromagnetic block embedded at the end of the travel limit block 18, and the magnetic attraction mating part 722 is preferably a ferromagnetic block embedded at the end of the force transmission member 72.
[0097] See Figure 6 Furthermore, the force-applying end 712 of the swing force-applying member 71 is provided with two force-applying balls 713. The two force-applying balls 713 are arranged opposite each other along the radial direction of the clamp body 1 and are located in the same horizontal direction. The end of the force-transmitting member 72 facing the swing force-applying member 71 is provided with a force-receiving groove 723 corresponding to each of the force-applying balls 713. Each force-receiving groove 723 extends in the vertical direction, and the inner contour of the force-receiving groove 723 is adapted to the outer contour of the force-applying ball 713. When the swing force-applying member 71 swings relative to the clamp body 1 with the bearing plate 21, the force-applying ball 713 is embedded in the corresponding force-receiving groove 723, and the outer peripheral surface of the force-applying ball 713 slides against the inner wall of the force-receiving groove 723.
[0098] Two force-applying balls 713 are arranged radially opposite to each other along the same horizontal direction on the clamp body 1, so that the two force-applying balls 713 are simultaneously embedded in two force-receiving grooves 723 on the same force-transmitting component 72. When the swinging force-applying component 71 swings with the bearing plate 21 relative to the clamp body 1, the two force-applying balls 713 simultaneously push the force-transmitting component 72, which helps to form a roughly balanced driving force on both sides of the radial direction of the force-transmitting component 72, so that the force-transmitting component 72 can slide relatively smoothly along the axial direction of the clamp body 1. The force-receiving grooves 723 extend vertically and their inner contours are adapted to the outer contours of the force-applying balls 713. The matching allows the force-applying ball 713 to move vertically relative to the force-receiving groove 723 when it swings with the swinging force-applying component 71. This helps to adapt to the positional changes of the force-applying ball 713 in the vertical direction during the swinging process and reduces interference caused by mismatch in the direction of movement. The outer peripheral surface of the force-applying ball 713 slides against the inner wall of the force-receiving groove 723, which helps to convert the swinging motion of the swinging force-applying component 71 into an axial pushing force on the force-transmitting component 72. This keeps the contact between the swinging force-applying component 71 and the force-transmitting component 72 stable, thereby reducing the risk of the cable 8 slipping out of the clamp under continuous swinging conditions.
