Description

Technical Field

[0001] The present application relates to the technical field of clamps, and in particular to a clamp for an electrosurgical cutting ring. Background Art

[0002] The electrosurgical cutting ring is a medical device commonly used in minimally invasive surgery. It is mainly used to cut tissue and stop bleeding through high-frequency electric current. It is widely used in urology, gynecology and other fields.

[0003] The electrosurgical cutting ring is mounted on an electrode holder. During the processing of the electrosurgical cutting ring, the electrode holder usually needs to be clamped and fixed first. Clamping and installation of the electrode holder is usually performed manually. However, as processing time and labor intensity increase, the clamping and installation accuracy of the electrode holder can easily decrease, resulting in reduced product quality. Summary of the Invention

[0004] In order to maintain the accuracy of clamping and installing the electrode holder, the present application provides a clamp for an electrosurgical cutting ring.

[0005] This application provides a clamp for an electric cutting ring, which adopts the following technical solution: A clamp for an electric cutting ring, comprising a workbench provided with a support column; A clamping seat, wherein a connecting column is provided at the bottom of the clamping seat, and the connecting column is hinged to the top of the support column, and the clamping seat can be flipped up and down to be parallel or perpendicular to the top surface of the workbench; A locking assembly is provided on the workbench, and when the clamping seat is flipped to be parallel to the top surface of the workbench, the locking assembly locks the clamping seat; An unlocking member, disposed on the clamping seat, and configured to unlock the clamping seat; A mounting block is provided on the side of the clamping seat facing away from the connecting column, the mounting block is provided with a mounting hole for the electrode holder to pass through, and a side wall of the mounting block against which the electric cutting ring on the electrode holder abuts serves as a calibration portion; a correction plate, symmetrically arranged and hinged to a side of the mounting block facing away from the calibration portion; A driving assembly is provided on the clamping seat, and when the clamping seat flips from a vertical state to a state parallel to the top surface of the workbench, the driving assembly drives the correction plate to flip simultaneously, so that the correction plates move closer to each other away from the side of the mounting block; A fixing plate is provided on a side of the clamping seat away from the connecting column, and the fixing plate includes a first fixing plate and a second fixing plate; The first fixing plate is symmetrically arranged and slides on the clamping seat, and the second fixing plate is symmetrically arranged and slides on the clamping seat in a direction close to or away from the connecting column. A fixing cavity for the electrode holder to pass through is formed between the first fixing plate and the second fixing plate. The sliding tracks of the first fixing plate and the second fixing plate are perpendicular. A fixing assembly is provided on the clamping seat, and when the clamping seat flips from a vertical state to be parallel to the top surface of the workbench, the fixing assembly drives the first fixing plate to approach each other and drives the second fixing plate to approach each other; When the clamping seat flips from a parallel state to a state perpendicular to the top surface of the workbench, the fixing assembly drives the fixing assembly to move away from each other relative to the first fixing plate and drives the fixing assembly to move away from each other relative to the second fixing plate.

[0006] By adopting the above technical solution, the clamping device utilizes support columns installed on the workbench. The connecting column at the bottom of the clamping base is hinged to the top of the support column, allowing the clamping base to be flipped up and down to be parallel or perpendicular to the workbench top surface. A locking assembly is installed on the workbench to lock the clamping base when it is flipped to be parallel to the workbench top surface; an unlocking member is installed on the clamping base to unlock the clamping base, allowing it to flip freely. The mounting block is located on the side of the clamping base facing away from the connecting column and has a mounting hole for the electrode holder to pass through. The side wall of the clamping block that abuts the electro-cutting ring on the electrode holder serves as the calibration portion. The correction plates are symmetrically arranged and hinged to the side of the mounting block facing away from the calibration portion. When the clamping base flips from a vertical position to be parallel to the workbench top surface, the correction plates simultaneously flip, bringing the plates away from the mounting block closer together to align the electrode holder. The fixing plate includes a first fixing plate and a second fixing plate, which secure the electrode holder. The entire process is simple, significantly reducing the complexity of electrode holder installation and facilitating accurate clamping and installation of the electrode holder.

[0007] Optionally, the locking assembly includes a locking post and a locking block; The workbench is provided with a mounting column, and when the clamping seat is parallel to the top surface of the workbench, the clamping seat abuts against the side of the mounting column away from the workbench; The locking column is arranged on a side of the mounting column away from the workbench, and the locking block is arranged on a side of the locking column away from the mounting column; The clamping seat is provided with a locking hole, the locking column and the locking block slide in the locking hole, and the locking block is provided with a locking surface which slides on the clamping seat when passing through the locking hole and is inclined away from the locking column. When the clamping seat abuts against the mounting column, the locking block abuts against a side of the clamping seat away from the workbench.

[0008] By adopting the above technical solution, the locking assembly includes a locking post and a locking block. When the clamping seat abuts the mounting post, the locking block abuts the side of the clamping seat away from the workbench, achieving locking. The locking assembly has a simple structure and is easy to operate. It can effectively lock the clamping seat, reduce the possibility of accidental tilting of the clamping seat during processing, and ensure the stability and safety of processing.

[0009] Optionally, the unlocking member is an unlocking column, which is slidably connected to a side of the clamping seat facing away from the connecting column, and the unlocking column pushes the locking block to be aligned with the locking hole.

[0010] By adopting the above technical solution, the unlocking member is an unlocking post. When unlocking is required, the unlocking post pushes the locking block to align with the locking hole, releasing the locking block from the clamping seat. The design of the unlocking member makes the clamping seat unlocking operation simple and quick, improving the flexibility of the clamp and facilitating quick adjustment of the clamping seat's state.

[0011] Optionally, the drive assembly includes a drive rope, a drive coil spring, and a drive shaft; The driving shaft is symmetrically arranged and rotatably connected to the mounting block, and the correction plates are respectively arranged on the driving shaft; The drive coil spring is wound around the outer periphery of the drive shaft, one end of the drive coil spring is clamped to the outer periphery of the drive shaft, and the other end is clamped to the mounting block; The driving rope is slidably arranged in the clamping seat and the mounting block, and the driving rope corresponds to the driving shaft one by one; The support column is provided with a rotation shaft, and the connecting column is rotatably connected to the rotation shaft; One end of the driving rope is connected to the outer circumference of the driving shaft. When the driving coil spring is elastically released, the driving rope is wound around the outer circumference of the driving shaft, and the other end of the driving rope is connected to the outer circumference of the rotating shaft. When the clamping seat is flipped over to be parallel to the top surface of the workbench, the driving rope is wound around the outer peripheral side of the rotating shaft. At this time, the driving shaft rotates and the driving coil spring elastically contracts.

[0012] By adopting the above technical solution, the drive assembly includes a drive rope, a drive coil spring, and a drive shaft. When the clamping base flips to be parallel to the top surface of the workbench, the drive rope is wrapped around the outer periphery of the rotating shaft, causing the drive shaft to rotate and the drive coil spring to elastically contract. The drive assembly utilizes the drive rope, drive coil spring, and drive shaft to automatically flip the correction plate when the clamping base flips, enabling the correction plate to promptly and effectively correct the electrode holder, thereby improving the fixture's automation and machining accuracy.

[0013] Optionally, the fixing assembly includes a fixing rope, a first bidirectional screw rod, a second bidirectional screw rod, a fixing coil spring and a fixing ball; The first bidirectional screw is rotatably connected to the clamping seat, and the first fixing plate is threadedly connected to the first bidirectional screw; There are multiple fixed balls that are evenly spaced and arranged on the outer circumference of one of the drive ropes. A plurality of fixed grooves are evenly spaced along the circumference of the outer circumference of the first bidirectional screw, and the fixed balls are accommodated in the fixed grooves. The second bidirectional screw is rotatably connected to the clamping seat, the second fixing plate is threadedly connected to the second bidirectional screw, the fixed coil spring is wound around the outer circumference of the second bidirectional screw, and the two ends of the fixed coil spring are respectively connected to the second bidirectional screw and the clamping seat; The fixing rope is wound around the outer circumference of the second bidirectional screw rod, one end of the fixing rope is connected to the second bidirectional screw rod, and the other end is connected to one of the driving ropes.

[0014] By adopting the above technical solution, the fixing assembly includes a fixing rope, a first bidirectional screw, a second bidirectional screw, a fixing coil spring, and a fixing ball. The fixing assembly drives the first and second fixing plates toward or away from each other through the rotation of the first and second bidirectional screws, thereby securing and releasing the electrode holder. The coordination between the fixing ball and the fixing slot, as well as the connection of the fixing rope, ensures the coordinated operation of the fixing assembly and the driving assembly, improving the reliability and stability of the fixation.

[0015] Optionally, the clamping seat is symmetrically and hingedly provided with limiting plates, and the driving rope is located between the limiting plates; A power block corresponding to the limiting plate is slidably connected in the clamping seat, and the clamping seat is provided with a driving spring that drives the power block to slide on the side of the limiting plate facing away from the driving rope, and at this time, the driving rope is clamped in cooperation with the limiting plate; The clamping seat is provided with a pushing member for driving the power block away from the limiting plate; The clamping seat is provided with a control groove symmetrically along the direction close to and away from the mounting block, and the clamping seat is provided with a control block that slides in the control groove; The control block is provided with a control hole for the driving rope to pass through, the control hole wall and the outer peripheral side of the driving rope have friction, and the clamping seat is provided with a control spring that drives the clamping seat to move away from the control block; The clamping seat is slidably connected with a control ball corresponding to the control groove one by one, and the clamping seat is provided with a power spring for driving the control ball to protrude into the control groove; When the control spring is released, the control block pushes the control ball to slide out of the control slot; A power rope connected to the power block is slidably provided in the clamping seat, and a control rope connected to the two control balls is provided at one end of the power rope away from the power block; A sliding ball located between the control blocks is slidably connected in the clamping seat, and a connecting spring is provided in the clamping seat to drive the sliding ball to slide until the driving rope is attached to the outer peripheral side of the sliding ball.

[0016] By adopting this technical solution, the clamping base is equipped with symmetrical, hinged restraint plates, with the drive rope positioned between the opposing restraint plates. By controlling the clamping and release of the drive rope, precise control of the drive assembly is achieved. The coordinated operation of the restraint plates, power block, control block, control ball, and control rope ensures the stability and reliability of the drive rope in various conditions, improving the overall performance of the clamp.

[0017] Optionally, the pushing member is a pushing column; The pushing column is slidably connected to the clamping seat, and the power block is inclined to open a pushing surface for the pushing column to slide. When the pushing column slides on the pushing surface, it pushes the power block away from the limiting plate.

[0018] By adopting the above technical solution, the pushing member is a pushing column. The design of the pushing column makes the movement of the power block more convenient and precise, and can quickly clamp and release the drive rope, thereby improving the operating efficiency of the clamp.

[0019] Optionally, the unlocking column is provided with a push bar slidably connected to the clamping seat, and the push column is inclined to have a connecting surface on the side away from the power block. The push bar slides on the connecting surface to push the push column to slide on the push surface.

[0020] By adopting the above technical solution, a push bar is provided on the unlocking column, which is slidably connected to the clamping seat. This structure realizes the linkage between the unlocking column and the push bar. When the unlocking column slides, the push bar pushes the push bar, thereby realizing the movement of the power block, making the unlocking and driving rope release operations more integrated, and improving the convenience of using the clamp.

[0021] In summary, this application has at least one of the following beneficial effects: 1. The mounting block is arranged on the side of the clamping seat facing away from the connecting column, and is provided with a mounting hole for the electrode holder to pass through, and the side wall on the side where the electric cutting ring on the electrode holder abuts is the calibration part. The correction plates are symmetrically arranged and hinged to the side of the mounting block facing away from the calibration part. When the clamping seat is flipped from a vertical state to a parallel top surface of the workbench, the correction plates are flipped at the same time, so that the correction plates are away from the side of the mounting block and close to each other, thereby correcting the electrode holder. The fixing plate includes a first fixing plate and a second fixing plate, and the electrode holder is fixed by the first fixing plate and the second fixing plate. The whole process is simple, which greatly reduces the complexity of the installation of the electrode holder and is conducive to maintaining the accuracy of the clamping installation of the electrode holder; 2. The clamping base has symmetrical and hinged limiting plates, and the drive rope is located between the opposing limiting plates. By controlling the clamping and release of the drive rope, precise control of the drive assembly is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following is combined with Figure 1-8 This application is described in further detail.

[0025] An embodiment of the present application discloses a clamp for an electrosurgical cutting ring.

[0026] See also Figure 1 and Figure 2 The fixture for the electrosurgical cutting ring includes a workbench 1 having a rectangular top surface. A support column 11 is fixedly connected to the top surface of the workbench 1. The support column 11 is located on one side of the top surface of the workbench 1 in a width direction and has a long square column structure. The support column 11 extends vertically upward.

[0027] The clamp for the electrosurgical ring also includes a clamping seat 2, a locking assembly 3, and an unlocking member. The clamping seat 2 is arranged above the workbench 1. The clamping seat 2 is a rectangular parallelepiped structure, and the length direction of the clamping seat 2 is parallel to the length direction of the top surface of the workbench 1. A connecting column 21 is fixedly connected to the bottom of the clamping seat 2, and the connecting column 21 is located in the width direction of the clamping seat 2. A rotating shaft 111 is fixedly connected to the top of the support column 11, and the connecting column 21 is rotatably connected to the outer peripheral side of the rotating shaft 111 to realize the hinged connection between the connecting column 21 and the support column 11, so that the clamping seat 2 can be flipped up and down to a state parallel to or perpendicular to the top surface of the workbench 1.

[0028] The locking assembly 3 is mounted on the workbench 1. When the clamping base 2 is tilted and aligned with the top surface of the workbench 1, it locks the clamping base 2. The locking assembly 3 includes a locking post 31 and a locking block 32. The workbench 1 is fixedly connected to a mounting post 12, located on the other side of the workbench 1's top surface, facing the support post 11. When the clamping base 2 is aligned with the top surface of the workbench 1, the clamping base 2 abuts against the mounting post 12 on the side facing away from the workbench 1.

[0029] The locking post 31 is fixedly connected to the side of the mounting post 12 away from the workbench 1. The locking block 32 is fixedly connected to the vertical side wall of the locking post 31 away from the support post 11, and the locking block 32 is located away from the mounting post 12. The clamping seat 2 is provided with a locking hole 22 extending in the vertical direction. When the clamping seat 2 is flipped to abut the mounting post 12, the locking post 31 and the locking block 32 slide through the locking hole 22. The locking block 32 is provided with a locking surface 321 on the side away from the locking post 31. When the locking post 31 and the locking block 32 slide through the locking hole 22, the locking surface 321 slides on the clamping seat 2, guiding the locking post 31 and the locking block 32 into the locking hole 22, at which time the locking post 31 undergoes elastic deformation. When the clamping seat 2 abuts the mounting column 12, the locking block 32 slides out of the locking hole 22, and the locking column 31 elastically recovers. At this time, the side of the locking block 32 close to the mounting column 12 abuts against the side of the clamping seat 2 away from the workbench 1, so that the clamping seat 2 enters a fixed state.

[0030] An unlocking member is provided on the clamping base 2, used to unlock the clamping base 2, allowing it to enter a freely reversible state. The unlocking member is an unlocking post 4. The clamping base 2 is provided with a T-shaped sliding groove, located on the side of the unlocking hole away from the mounting post 12. A T-shaped slider is fixedly connected to the unlocking post 4. The slider slides within the sliding groove, allowing the unlocking post 4 to slide toward or away from the mounting post 12 on the side of the clamping base 2 facing away from the connecting post 21. During use, the unlocking post 4 is slid toward the mounting post 12, at which point the unlocking post 4 pushes the locking block 32 into alignment with the locking hole 22, allowing the clamping base 2 to enter a freely reversible state.

[0031] The clamp for the electrosurgical ring also includes a mounting block 5 and a correction plate 53. The mounting block 5 is fixedly connected to the side of the clamping seat 2 facing away from the connecting column 21. The mounting block 5 has a mounting hole 51, and the mounting hole 51 extends along the length of the clamping seat 2. During installation, the clamping seat 2 is placed perpendicular to the top plane of the workbench 1. At this time, the electrode holder is moved away from the side of the electrosurgical ring and passed through the mounting hole 51 from the side of the mounting hole 51 away from the connecting column 21 toward the connecting column 21. The side of the mounting block 5 away from the connecting column 21 is the calibration portion 52. Under the action of gravity, the electrode holder can keep the electrosurgical ring in contact with the calibration portion 52, which helps to improve the accuracy of the motor holder after installation.

[0032] The correction plates 53 are hinged to the side of the mounting block 5 facing away from the calibration portion 52. Two correction plates 53 are symmetrically arranged. The clamp for the electrosurgical cutting ring also includes a drive assembly 6, which is mounted on the clamping base 2. When the clamping base 2 is tilted from a vertical position to parallel to the top surface of the workbench 1, the drive assembly 6 simultaneously rotates the correction plates 53, bringing the correction plates 53 away from the hinge point with the mounting block 5 closer together, correcting the electrode holder, improving the installation accuracy, and reducing the difficulty of the electrode holder installation.

[0033] The drive assembly 6 includes a drive rope 61, a drive coil spring 62, and a drive shaft 63. The drive shaft 63 is rotatably connected to the mounting block 5. There are two drive shafts 63, symmetrically arranged, with one drive shaft 63 corresponding to each correction plate 53. The two correction plates 53 are respectively fixedly connected to the drive shaft 63. The drive coil spring 62 is wound around the outer periphery of the drive shaft 63 and is located within the mounting block 5. One end of the drive coil spring 62 is engaged with the outer periphery of the drive shaft 63, and the other end is engaged with the mounting block 5. When the drive coil spring 62 is released, it drives the two drive shafts 63 to rotate, causing the two correction plates 53 to move away from each other on the side away from the drive shaft 63.

[0034] The drive rope 61 is slidably arranged in the clamping seat 2 and the mounting block 5. There are two drive ropes 61, which correspond to the two drive shafts 63 one by one. The drive rope 61 is wound around the outer periphery of the rotating shaft 111. One end of the drive rope 61 is fixedly connected to the outer periphery of the rotating shaft 111, and one end of the drive rope 61 is fixedly connected to the outer periphery of the driving shaft 63. When the drive coil spring 62 is elastically released, the drive rope 61 is wound around the outer periphery of the driving shaft 63; when the clamping seat 2 is flipped to be parallel to the top surface of the workbench 1, the drive rope 61 is wound around the outer periphery of the rotating shaft 111. At this time, the driving shaft 63 rotates to release the drive rope 61, and the drive coil spring 62 enters an elastic contraction state, driving the two correction plates 53 to rotate, so that the two correction plates 53 move closer to each other away from the side of the driving shaft 63. When the two correction plates 53 move closer to each other away from the side of the driving shaft 63, the electrode holder is corrected, thereby improving the accuracy of the electrode holder installation and reducing the complexity of the electrode holder installation.

[0035] See also Figure 2 and Figure 3The clamp for the electrosurgical ring also includes a fixing plate 7 and a fixing assembly 8. The fixing plate 7 is arranged on the clamping seat 2. The fixing plate 7 is located on the side of the clamping seat 2 away from the connecting column 21. The fixing plate 7 includes a first fixing plate 71 and a second fixing plate 72. The first fixing plate 71 slides on the end face of one side of the connecting column 21 of the clamping seat 2. There are two first fixing plates 71 and they are symmetrically arranged. The second fixing plate 72 is slidably arranged on the clamping seat 2 in a direction close to or away from the connecting column 21. There are two second fixing plates 72 and they are symmetrically arranged. The sliding tracks of the first fixing plate 71 and the second fixing plate 72 are perpendicular. A fixed cavity 73 that is interconnected is formed between the two first fixing plates 71 and the two second fixing plates 72, and the electrode holder passes through the fixed cavity 73.

[0036] The fixing assembly 8 is disposed on the clamping seat 2. When the clamping seat 2 is flipped from a vertical position to be parallel to the top surface of the workbench 1, the fixing assembly 8 drives the two relative first fixing plates 71 toward each other, so that the two first fixing plates 71 clamp and fix the electrode holder. At the same time, the fixing assembly 8 drives the two relative second fixing plates 72 toward each other, so that the two second fixing plates 72 clamp and fix the electrode holder. At this time, the electrode holder enters a fixed state. When the clamping seat 2 is flipped from a parallel position to be perpendicular to the top surface of the workbench 1, the fixing assembly 8 drives the two relative first fixing plates 71 away from each other and drives the two relative second fixing plates 72 away from each other, so that the electrode holder enters a detachable state.

[0037] See also Figure 3 and Figure 4 The fixing assembly 8 includes a fixing rope 81, a first bidirectional screw 82, a second bidirectional screw 83, a fixing coil spring 84, and a fixing ball 85. The first bidirectional screw 82 is rotatably connected to the clamping base 2, with the central axis of the first bidirectional screw 82 being perpendicular to the longitudinal direction of the end face of the clamping base 2 on the side away from the connecting column 21. The two first fixing plates 71 are respectively threadedly connected to the positive and negative thread segments of the first bidirectional screw 82. When the first bidirectional screw 82 rotates, the two first fixing plates 71 simultaneously move toward or away from each other.

[0038] A plurality of fixed balls 85 are fixed to the outer circumference of one of the drive ropes 61, and are evenly spaced. The outer circumference of the first bidirectional screw rod 82 is provided with multiple fixed grooves, which are evenly spaced along the circumference. The fixed balls 85 are accommodated in the grooves. When the drive rope 61 slides, the fixed balls 85 drive the first bidirectional screw rod 82 into rotation.

[0039] The second bidirectional screw 83 is rotatably connected to the side of the clamping base 2 away from the connecting post 21. The two second fixing plates 72 are respectively threadedly connected to the positive and negative threaded sections of the second bidirectional screw 83. A guide rod is fixedly connected to the side of the clamping base 2 away from the connecting post 21, and the two second fixing plates 72 are respectively slidably connected to the guide rod. A fixed coil spring 84 is wrapped around the outer periphery of the second bidirectional screw 83. One end of the fixed coil spring 84 is clamped and fixed to the outer periphery of the second bidirectional screw 83, and the other end is clamped to the clamping base 2. A fixed rope 81 is slidably inserted into the clamping base 2. The fixed rope 81 is wrapped around the outer periphery of the second bidirectional screw 83. One end of the fixed rope 81 is fixedly connected to the second bidirectional screw 83, and the other end is fixedly connected to one of the drive ropes 61. When the drive rope 61 is wrapped around the outer periphery of the rotating shaft 111, the fixed rope 81 is pulled, causing the second bidirectional screw 83 to rotate, driving the two second fixing plates 72 toward each other, securing the electrode holder, and simultaneously causing the fixed coil spring 84 to elastically contract. When the rotating shaft 111 releases the driving rope 61 , the fixed coil spring 84 enters an elastically relaxed state, driving the second bidirectional screw 83 to rotate in the opposite direction, driving the two second fixing plates 72 to move away from each other, and loosening the electrode bracket.

[0040] See also Figure 5 and Figure 6 , a limiting plate 23 is hinged in the clamping seat 2, and there are two groups of limiting plates 23 and they are symmetrically arranged. Each group of limiting plates 23 corresponds to a driving rope 61, and each group of limiting plates 23 has two and they are symmetrically arranged. The driving rope 61 is located between the two limiting plates 23 in the same group. A power block 24 is slidably connected in the clamping seat 2, and there are two power blocks 24 and they correspond one-to-one to the two groups of limiting plates 23. The power blocks 24 are in a "U"-shaped structure, and the two ends of the power blocks 24 correspond one-to-one to the two limiting plates 23 in the same group. The clamping seat 2 is provided with a driving spring 241, and there are two driving springs 241 and they correspond one-to-one to the two power blocks 24. The driving spring 241 is located in the clamping seat 2, and one end of the driving spring 241 abuts against the side of the power block 24 away from the limiting plate 23, and the other end abuts against the clamping seat 2. When the driving spring 241 is elastically released, the driving power block 24 slides on the side of the limiting plate 23 facing away from the driving rope 61 . At this time, the power block 24 pushes the two limiting plates 23 in the same group to cooperate with each other to clamp the driving rope 61 .

[0041] See also Figure 6 and Figure 7 The clamping seat 2 is provided with a pushing member to drive the power block 24 away from the limiting plate 23, so that the two limiting plates 23 in the same group loosen the driving rope 61, which is conducive to the driving rope 61 entering a free sliding state.

[0042] See also Figure 6 and Figure 8The pushing member is a pushing column 25, which is slidably connected to the side of the clamping seat 2 away from the connecting column 21. The power block 24 is inclined to open a pushing surface 244, and the pushing column 25 slides on the pushing surface 244, pushing the power block 24 away from the limiting plate 23. A pushing bar 41 is fixedly connected to the unlocking column 4, and the pushing bar 41 is slidably connected to the clamping seat 2. The pushing column 25 is inclined to open a connecting surface 251 on the side away from the power block 24, and the pushing bar 41 slides on the connecting surface 251. When the unlocking column 4 pushes the unlocking block to be aligned with the unlocking hole, the pushing column 25 drives the pushing bar 41 to slide, so that the pushing column 25 slides on the connecting surface 251. At this time, the pushing column 25 slides on the pushing surface 244, achieving the purpose of moving the power block 24 away from the limiting plate 23.

[0043] See also Figure 6 and Figure 7 The clamping base 2 is provided with a control slot 26 extending in a direction close to and away from the mounting block 5. There are two symmetrical control slots 26, and the control slots 26 are located near the rotation axis 111. The clamping base 2 is provided with a plurality of control blocks 261, which correspond one to one with the control slots 26, and the control blocks 261 slide in the control slots 26.

[0044] The control block 261 defines a control hole 262, through which the drive rope 61 slides. Friction is generated between the wall of the control hole 262 and the outer periphery of the drive rope 61. The clamping base 2 is provided with a control spring 27, which is sleeved around the outer periphery of the drive rope 61 and mounted within the control slot 26. One end of each of the control springs 27 abuts the opposing sides of the two control blocks 261, while the other end abuts the wall of the control slot 26. When the control springs 27 are released, they drive the two control blocks 261 away from each other, causing them to abut the opposing walls of the two control slots 26. When the rotating shaft 111 is wound around the driving rope 61, the driving rope 61 drives the control block 261 close to the mounting block 5 to slide and squeeze the control spring 27 under the action of friction, and the other control block 261 is in a stationary state; when the rotating shaft 111 releases the driving rope 61, the driving rope 61 drives the control block 261 away from the mounting block 5 to slide and squeeze the control spring 27 under the action of friction, and the other control block 261 is in a stationary state; when the driving rope 61 stops sliding, the elastic force of the control spring 27 pushes the control block 261 to abut against the wall of the control groove 26.

[0045] A control ball 28 is slidably connected within the clamping seat 2. There are multiple control balls 28, each corresponding one-to-one with the control slot 26. A power spring 281 is provided within the clamping seat 2. There are multiple power springs 281, each corresponding one-to-one with the control balls 28. One end of the control spring 27 abuts the end of the control ball 28 away from the drive rope 61, and the other end of the control spring 27 abuts the clamping seat 2. When the control spring 27 pushes the control block 261 against the wall of the control slot 26, the control block 261 pushes the control ball 28 out of the control slot 26. When the control spring 27 is released, the control ball 28 is driven to protrude into the control slot 26. When the drive rope 61 slides, causing the control block 261 to squeeze the control spring 27, the control block 261 pushes the control ball 28 out of the control slot 26, at which point the power spring 281 enters a compressed state.

[0046] A power rope 242 is slidably threaded through the clamping base 2, corresponding one-to-one with the power block 24. One end of the power rope 242 is fixedly connected to the power block 24. The end of the power rope 242 facing away from the power block 24 is fixedly connected to two control ropes 243, each of which passes through a power spring 281 and is secured to a control ball 28. A sliding ball 29 is slidably connected to the clamping base 2, positioned between two opposing control blocks 261. A connecting spring 291 is provided within the clamping base 2. One end of the connecting spring 291 abuts the end of the sliding ball 29 facing away from the drive rope 61, while the other end abuts the clamping base 2. When the connecting spring 291 is released, the driving sliding ball 29 slides and first abuts the drive rope 61, then continues to push the sliding ball 29, causing the drive rope 61 to adhere to the outer periphery of the sliding ball 29. This increases the length of the drive rope 61 between the two opposing control blocks 261.

[0047] The implementation principle of a clamp for an electric cutting ring in the embodiment of the present application is as follows: During installation, the clamping seat 2 is in a vertical state with respect to the top surface of the workbench 1. At this time, the electrode holder is passed through the mounting hole 51 and the fixing cavity 73 from top to bottom away from the side of the electrocuting ring until the electrocuting ring abuts against the calibration portion 52. Then the clamping seat 2 is flipped over until it is parallel to the top surface of the workbench 1, so that the clamping seat 2 is fixed. During the flipping process of the clamping seat 2, the drive rope 61 pulls the drive shaft 63, so that the correction plate 53 corrects the electrode holder, and the fixing plate 7 fixes the electrode holder. During the flipping process of the clamping seat 2, the drive rope 61 pulls the control block 261 close to the mounting block 5, so that the corresponding control ball 28 slides into the control groove 26. At this time, the control rope 243 pulls the power block 24 through the power rope 242, so that the power block 24 is away from the limiting plate 23, and the limiting plate 23 keeps the driving rope 61 relaxed. When the correction plate 53 completes the correction and the fixing plate 7 fixes the electrode holder, the driving rope 61 stops sliding at the control block 261 near the mounting block 5. At this time, the control block 261 pushes the control ball 28 to slide out of the control groove 26, and the power block 24 pushes the limiting plate 23 to clamp the driving rope 61. Then, the clamping seat 2 continues to flip toward the state parallel to the top surface of the workbench 1. The driving rope 61 drives the sliding ball 29 to slide, causing the connecting spring 291 to enter a compressed state.

[0048] When the electrode holder needs to be removed, the clamping base 2 is first unlocked and simultaneously flipped to a position perpendicular to the top surface of the workbench 1. At this time, the limiting plate 23 is in a state of loosening the drive rope 61. Then, during the flipping process of the clamping base 2, the connecting spring 291 first pushes the sliding ball 29, driving the drive rope 61 to fit the outer periphery of the sliding ball 29. At this time, the drive rope 61 pulls the control block 261 near the rotating shaft 111, causing the limiting plate 23 to maintain the state of loosening the drive rope 61. At the same time, the drive shaft 63 winds the drive rope 61, causing the correction plate 53 to loosen the electrode holder. At the same time, the first fixing plate 71 and the second fixing plate 72 loosen the electrode holder, and the electrode holder enters a detachable state.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
