Description
Technical Field
[0001] This invention belongs to the field of medical device clamping technology, and particularly relates to a medical device clamping device that can prevent interference and allow for rapid changeover. Background Technology
[0002] Medical device clamps are essential tooling in the production, assembly, testing, and sterilization of medical devices. Their main function is to accurately position and stably clamp various medical devices, ensuring that related processes can be completed smoothly and accurately.
[0003] Currently, most medical device clamps on the market are integrated fixed structures that cannot be replaced individually. When producing medical devices of different specifications and shapes, the entire clamp must be replaced. This not only significantly increases the equipment procurement costs for enterprises, but also requires disassembling and reinstalling the entire clamp during line changeover, which is time-consuming and labor-intensive, seriously affecting production efficiency. The adjustment freedom of existing clamps is very limited, with most only having the function of opening and closing the grippers, and a few clamps having a simple height adjustment function. They cannot achieve flexible adjustment of the clamping angle and horizontal position. In multi-device collaborative operation or complex workstation environments, clamps are very likely to interfere with surrounding equipment, workpieces, or operators, which not only affects the smoothness of operation, but also poses significant safety hazards. In view of this, we propose a medical device clamp that can prevent interference and quickly change types. Summary of the Invention
[0004] The purpose of this invention is to provide a medical device clamp that can prevent interference and allow for rapid changeover, in order to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a medical device clamp that can prevent interference and allow for rapid changeover, comprising: The base has a rotating groove on its top, in which a rotating disk is rotatably mounted. Several protrusions are fixedly mounted on the periphery of the rotating disk. A support rod is fixedly mounted on the top of the rotating disk. A fixing block is provided at the top of the support rod. A turntable is rotatably mounted on one side of the fixing block. A mounting plate is fitted on one side of the turntable. An internal hexagon bolt is threaded onto the top of the mounting plate. The bottom end of the internal hexagon bolt extends into the turntable. A clamping claw is symmetrically and slidably mounted on one side of the mounting plate. One side of the clamping claw is provided with anti-slip texture. A lifting assembly, located inside a support rod, is used to drive a fixed block to move up and down; A drive assembly, located within a fixed block, is used to drive the turntable to rotate; A power assembly, located on a mounting plate, is used to drive the two grippers to move closer or further apart.
[0006] In this technical solution, the mounting plate and the turntable are connected by a hexagon socket bolt. The mounting plate and the turntable are pre-positioned by a plug-in connection and then fastened by the hexagon socket bolt. The bottom end of the hexagon socket bolt is threaded to the turntable, which firmly fixes the mounting plate to the side of the turntable. When it is necessary to change the gripper to fit different shapes and sizes of medical devices, the operator only needs to use an hexagon wrench to loosen the hexagon socket bolt, release the fixing constraint between the mounting plate and the turntable, and then pull the mounting plate and its two grippers out of the turntable. After replacing the mounting plate with the corresponding size gripper, the new mounting plate is inserted into the corresponding interface of the turntable, and the hexagon socket bolt is tightened again to complete the entire changeover operation. This process does not require disassembling the lifting, driving and other core components of the clamp, the changeover time is short and the operation is simple, and it realizes the rapid switching of different grippers. The opening and closing action of the gripper is driven by the power component to achieve the clamping and releasing action of the medical device. The side of the gripper that contacts the medical device is provided with anti-slip texture, which can effectively increase the clamping friction and prevent the medical device from sliding or falling off during clamping or adjustment, thereby improving the clamping stability. The clamping angle of the gripper is adjusted by the drive component, which in turn drives the mounting plate and the two grippers to rotate 360 degrees around the axis of the turntable, so as to realize the arbitrary adjustment of the gripper clamping angle. At the same time, the worm gear transmission structure has a self-locking characteristic. After the adjustment is completed, the gripper can be stably maintained at the set angle and will not deflect due to clamping force or external force, thus ensuring the accuracy of the clamping posture. The gripping height of the gripper is adjusted by the lifting component, which can adapt to medical devices of different heights and sizes as well as different operating station requirements, avoiding gripping interference problems caused by unsuitable height; The entire clamp can be rotated 360 degrees in the horizontal plane. The rotating disk is mounted in the rotating groove on the top of the base. Several protrusions are fixedly installed on the periphery of the rotating disk, which makes it easy for the operator to manually apply force to rotate the rotating disk. When the rotating disk rotates, it will drive the support rod fixed on its top and all the components above the support rod to rotate around the axis of the base, realizing the all-round position adjustment of the gripper in the horizontal plane. This function further expands the working range of the clamp, which can flexibly avoid the interference area of surrounding equipment and instruments and meet the clamping needs under complex working conditions.
[0007] In the above technical solution, the lifting component further includes: A lifting groove is provided, which is located inside a support rod. A lifting rod is slidably installed inside the lifting groove. The top end of the lifting rod passes through the top of the lifting groove and is fixedly connected to a fixing block. A threaded rod is rotatably installed inside the lifting groove. The top end of the threaded rod extends into the lifting rod. A groove is provided inside the support rod and below the lifting groove. A drive motor is fixedly installed in the groove. The output end of the drive motor passes through the top of the groove and is coaxially connected to the threaded rod.
[0008] In this technical solution, the clamping height of the gripper is adjusted by the lifting assembly. The drive motor is installed in the groove inside the support rod. After the drive motor is started, its output shaft drives the threaded rod to rotate in the lifting groove. The threaded rod is threadedly connected to the lifting rod, converting the rotational motion of the threaded rod into the linear lifting motion of the lifting rod. The lifting rod slides up and down along the lifting groove, driving the fixed block fixedly connected to its top to rise and fall synchronously. The fixed block drives the gripper as a whole to adjust its height through the turntable and mounting plate, which can adapt to medical devices of different heights and sizes as well as different operating station requirements, avoiding clamping interference problems caused by unsuitable height.
[0009] In the above technical solution, the threaded rod is threadedly connected to the lifting rod, and the output shaft of the drive motor is rotatably connected to the support rod.
[0010] In this technical solution, it is ensured that the rotation of the threaded rod can drive the lifting rod to rise and fall, and that the output shaft of the drive motor can rotate normally within the support rod.
[0011] In the above technical solution, the driving component further includes: A drive groove is formed inside a fixed block. A worm gear is rotatably installed inside the drive groove. One end of the worm gear passes through one side of the drive groove and is coaxially connected to a turntable. A worm is meshed with the bottom of the worm gear and located inside the drive groove. One end of the worm passes through the drive groove and is fixedly installed with a knob.
[0012] In this technical solution, the clamping angle of the grippers is adjusted by the drive assembly. Rotating the knob on the side of the fixed block drives the worm to rotate in the drive groove. The worm meshes with the worm wheel, converting the rotational motion of the worm into the rotational motion of the worm wheel. Since one end of the worm wheel is coaxially fixedly connected to the turntable, the rotation of the worm wheel will drive the turntable to rotate synchronously, thereby driving the mounting plate and the two grippers to rotate 360 degrees around the axis of the turntable, realizing arbitrary adjustment of the gripper clamping angle. At the same time, the worm wheel and worm gear transmission structure has a self-locking characteristic. After adjustment, the grippers can be stably maintained at the set angle and will not deflect due to clamping force or external force, ensuring the accuracy of the clamping posture.
[0013] In the above technical solution, the worm gear is further rotatably connected to the drive groove.
[0014] In this technical solution, it is ensured that the worm can rotate normally within the drive slot.
[0015] In the above technical solution, the power component further includes: The movable slot is formed inside the mounting plate. A rack is fixedly installed on the gripper and inside the movable slot. A gear 1 is meshed on one side of the rack and inside the movable slot. A gear 2 is meshed on one side of one gear 1 and inside the movable slot. A gear 3 is meshed on one side of another gear 1 and inside the movable slot. A drive motor 2 is fixedly installed on the top of the mounting plate. The output end of the drive motor 2 passes through the top of the mounting plate and is coaxially connected to the gear 2.
[0016] In this technical solution, the opening and closing action of the grippers is driven by a power component. After the drive motor 2 starts, its output shaft drives gear 2 to rotate synchronously. Gear 2 simultaneously meshes with gear 3 and one of the gears 1, causing gear 3 to rotate in the opposite direction to gear 1. Gear 3 then meshes with another gear 1, causing it to rotate synchronously in the opposite direction. The two gears 1 respectively mesh with the racks on the two grippers, converting the rotational motion of the gears into the linear reciprocating motion of the racks, thereby driving the two grippers to move closer or further away from each other synchronously on the mounting plate, realizing the clamping and releasing action of the medical device. The side of the gripper that contacts the medical device is provided with anti-slip texture, which can effectively increase the clamping friction and prevent the medical device from sliding or falling off during clamping or adjustment, thus improving the clamping stability.
[0017] In the above technical solution, gear one, gear two, and gear three are all rotatably connected to the movable slot, gear two and gear three mesh with each other, and the output shaft of the drive motor two is rotatably connected to the mounting plate.
[0018] In this technical solution, it is ensured that gear one, gear two, and gear three can rotate normally within the movable slot, the structure of gear two and gear three is kept stable, and the output shaft of drive motor two can rotate normally within the mounting plate.
[0019] In the above technical solution, furthermore, the bottom end of the internal hexagonal bolt is threadedly connected to the turntable, and the turntable is plugged into the mounting plate.
[0020] In this technical solution, it is ensured that the internal hex bolts can be screwed into the turntable, and that the turntable can be inserted into the mounting plate.
[0021] The beneficial effects of this invention are: 1. This interference-resistant, quick-change medical device clamp uses hexagonal bolts to detachably connect the mounting plate to the turntable, creating a quick-change structure. When it is necessary to change the gripper to fit different medical devices, the operator only needs to loosen a single hexagonal bolt with an Allen wrench to pull the mounting plate and its two grippers off the turntable as a whole. After replacing the mounting plate with one that has grippers of the corresponding specifications, the bolts are tightened again to complete the changeover. The entire process does not require disassembling the clamp's lifting, drive, or other core components, making the operation simple and quick, significantly shortening changeover time and reducing the company's equipment investment costs.
[0022] 2. This interference-resistant and quick-change medical device clamp can achieve 360-degree rotation in the horizontal plane by rotating the rotating disk installed in the rotating slot of the base. The lifting component can drive the fixed block and the gripper to adjust the vertical height, and the driving component can drive the rotating disk and the gripper to adjust the clamping angle. The coordinated operation of these three degrees of freedom can adjust the clamping posture of the gripper in all directions and flexibly, effectively avoiding the interference area of surrounding equipment and instruments, and significantly improving the applicability and operational safety of the clamp.
[0023] 3. This interference-resistant and quick-change medical device clamp uses a gear and rack transmission structure to drive the jaws to open and close synchronously, ensuring the synchronous movement of the two jaws and the uniformity of clamping force. The side of the jaw that contacts the medical device is provided with anti-slip texture, which can effectively increase the clamping friction and prevent the medical device from slipping and falling off during clamping or adjustment. The drive component adopts a worm gear transmission structure, which utilizes its inherent self-locking characteristics. After adjustment, the jaw can be stably held at the set angle without accidental deflection, further improving the stability and reliability of clamping. Attached Figure Description

[0031] Example 1:
[0032] Please see Figures 1-5 As shown, this embodiment provides a medical device clamp that can prevent interference and allow for rapid changeover, including: The base 1 has a rotating groove 2 on its top. A rotating disk 3 is rotatably installed in the rotating groove 2. Several protrusions 4 are fixedly installed on the periphery of the rotating disk 3. A support rod 5 is fixedly installed on the top of the rotating disk 3. A fixing block 26 is provided at the top of the support rod 5. A turntable 10 is rotatably installed on one side of the fixing block 26. A mounting plate 11 is fitted on one side of the turntable 10. An internal hex bolt 12 is threaded on the top of the mounting plate 11. The bottom end of the internal hex bolt 12 extends into the turntable 10. A clamp 17 is symmetrically and slidably installed on one side of the mounting plate 11. An anti-slip texture 18 is provided on one side of the clamp 17. The lifting assembly is located inside the support rod 5 and is used to drive the fixed block 26 to lift. The drive assembly is located within the fixed block 26 and is used to drive the turntable 10 to rotate. A power assembly is located on the mounting plate 11 and is used to drive the two grippers 17 to move closer or further apart.
[0033] The system utilizes the cooperation between the hexagon socket bolt 12, the turntable 10, and the mounting plate 11. The mounting plate 11 and the turntable 10 are pre-positioned by a plug-in connection and then fastened by the hexagon socket bolt 12. The bottom end of the hexagon socket bolt 12 is threaded to the turntable 10, firmly fixing the mounting plate 11 to the side of the turntable 10. When it is necessary to replace the gripper 17 to adapt to different shapes and sizes of medical devices, the operator only needs to use an hexagon wrench to loosen the hexagon socket bolt 12, release the fixing constraint between the mounting plate 11 and the turntable 10, and then pull the mounting plate 11 and the two grippers 17 on it out of the turntable 10. After replacing the mounting plate 11 with the corresponding specification gripper 17, the new mounting plate 11 is inserted into the corresponding interface of the turntable 10, and the hexagon socket bolt 12 is tightened again to complete the entire changeover operation. This process does not require disassembling the core components of the clamp, such as the lifting and driving mechanism, and the changeover time is short and the operation is simple, realizing the rapid switching of different grippers 17. The opening and closing action of the gripper 17 is driven by the power component to achieve the clamping and releasing action of the medical device. The side of the gripper 17 that contacts the medical device is provided with anti-slip texture 18, which can effectively increase the clamping friction, prevent the medical device from sliding or falling off during clamping or adjustment, and improve clamping stability. The clamping angle of the gripper 17 is adjusted by the drive component, which in turn drives the mounting plate 11 and the two grippers 17 to rotate 360 degrees around the axis of the turntable 10, so as to realize the arbitrary adjustment of the clamping angle of the gripper 17. After the adjustment is completed, the gripper 17 can be stably maintained at the set angle and will not deflect due to clamping force or external force, thus ensuring the accuracy of the clamping posture. The clamping height of the gripper 17 is adjusted by the lifting component, which can adapt to medical devices of different heights and sizes as well as different operating station requirements, avoiding clamping interference problems caused by unsuitable height. The entire fixture can be rotated 360 degrees in the horizontal plane. The rotating disk 3 is rotatably installed in the rotating groove 2 on the top of the base 1. Several protrusions 4 are fixedly installed on the periphery of the rotating disk 3, which makes it easy for the operator to manually apply force to rotate the rotating disk 3. When the rotating disk 3 rotates, it will drive the support rod 5 fixed on its top and all the components above the support rod 5 to rotate around the axis of the base 1, realizing the all-round position adjustment of the gripper 17 in the horizontal plane. This function further expands the working range of the fixture, which can flexibly avoid the interference area of surrounding equipment and instruments, and meet the clamping needs under complex working conditions.
[0034] Example 2:
[0035] This embodiment provides a medical device clamp that can be quickly changed without interference. In addition to the technical solutions of the above embodiments, it also has the following technical features: the lifting assembly includes: A lifting groove 6 is formed inside the support rod 5. A lifting rod 7 is slidably installed inside the lifting groove 6. The top end of the lifting rod 7 passes through the top of the lifting groove 6 and is fixedly connected to the fixing block 26. A threaded rod 8 is rotatably installed inside the lifting groove 6. The top end of the threaded rod 8 extends into the lifting rod 7. A groove 25 is formed inside the support rod 5 and below the lifting groove 6. A drive motor 9 is fixedly installed inside the groove 25. The output end of the drive motor 9 passes through the top of the groove 25 and is coaxially connected to the threaded rod 8.
[0036] The clamping height of the gripper 17 is adjusted by the lifting assembly. The drive motor 9 is installed in the groove 25 inside the support rod 5. After the drive motor 9 is started, its output shaft drives the threaded rod 8 to rotate in the lifting groove 6. The threaded rod 8 is threadedly connected to the lifting rod 7, converting the rotational motion of the threaded rod 8 into the linear lifting motion of the lifting rod 7. The lifting rod 7 slides up and down along the lifting groove 6, driving the fixed block 26 fixedly connected to its top to rise and fall synchronously. The fixed block 26 drives the gripper 17 to adjust its overall height through the turntable 10 and the mounting plate 11, which can adapt to medical devices of different heights and sizes as well as different operating station requirements, avoiding clamping interference problems caused by unsuitable height.
[0037] Example 3:
[0038] This embodiment provides a medical device clamp that can prevent interference and allow for rapid changeover. In addition to the technical solutions of the above embodiments, it also has the following technical features: the threaded rod 8 is threadedly connected to the lifting rod 7, and the output shaft of the drive motor 9 is rotatably connected to the support rod 5.
[0039] Specifically, it ensures that the rotation of the threaded rod 8 can drive the lifting rod 7 to rise and fall, and ensures that the output shaft of the drive motor 9 can rotate normally within the support rod 5.
[0040] Example 4:
[0041] This embodiment provides a medical device clamp that can prevent interference and allow for rapid changeover. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a driving component comprising: A drive groove 13 is formed inside a fixed block 26. A worm gear 14 is rotatably installed inside the drive groove 13. One end of the worm gear 14 passes through one side of the drive groove 13 and is coaxially connected to the turntable 10. A worm 15 is meshed and installed at the bottom of the worm gear 14 and inside the drive groove 13. One end of the worm 15 passes through the drive groove 13 and is fixedly installed with a knob 24.
[0042] The clamping angle of the gripper 17 is adjusted by the drive assembly. Rotating the knob 24 on the side of the fixing block 26 drives the worm 15 to rotate in the drive groove 13. The worm 15 meshes with the worm wheel 14, converting the rotational motion of the worm 15 into the rotational motion of the worm wheel 14. Since one end of the worm wheel 14 is coaxially fixedly connected to the turntable 10, the rotation of the worm wheel 14 will drive the turntable 10 to rotate synchronously, thereby driving the mounting plate 11 and the two grippers 17 to rotate 360 degrees around the axis of the turntable 10, realizing arbitrary adjustment of the clamping angle of the gripper 17. At the same time, the worm wheel 14 and worm 15 transmission structure has a self-locking characteristic. After the adjustment is completed, the gripper 17 can be stably maintained at the set angle and will not deflect due to clamping force or external force, ensuring the accuracy of the clamping posture.
[0043] Example 5:
[0044] This embodiment provides a medical device clamp that can prevent interference and allow for rapid changeover. In addition to the technical solutions of the above embodiments, it also has the following technical features: the worm gear 15 is rotatably connected to the drive groove 13.
[0045] This ensures that the worm gear 15 can rotate normally within the drive slot 13.
[0046] Example 6:
[0047] This embodiment provides a medical device clamp that can prevent interference and allow for rapid changeover. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the power assembly includes: The movable slot 16 is opened inside the mounting plate 11. A rack 19 is fixedly installed on the gripper 17 and inside the movable slot 16. A gear 20 is meshed on one side of the rack 19 and inside the movable slot 16. A gear 21 is meshed on one side of one gear 20 and inside the movable slot 16. A gear 3 22 is meshed on one side of the other gear 20 and inside the movable slot 16. A drive motor 23 is fixedly installed on the top of the mounting plate 11. The output end of the drive motor 23 passes through the top of the mounting plate 11 and is coaxially connected to the gear 21.
[0048] The opening and closing action of the gripper 17 is driven by the power component. After the drive motor 23 starts, its output shaft drives the gear 21 to rotate synchronously. The gear 21 simultaneously meshes with the gear 3 22 and one of the gears 1 20, causing the gear 3 22 to rotate in the opposite direction to the gear 1 20. The gear 3 22 then meshes with the other gear 1 20, causing it to rotate synchronously in the opposite direction. The two gears 1 20 mesh with the racks 19 on the two grippers 17 respectively, converting the rotational motion of the gears into the linear reciprocating motion of the racks 19. This drives the two grippers 17 to move synchronously closer or further away from each other on the mounting plate 11, realizing the clamping and releasing action of the medical device. The side of the gripper 17 that contacts the medical device is provided with anti-slip texture 18, which can effectively increase the clamping friction and prevent the medical device from sliding or falling off during clamping or adjustment, thereby improving the clamping stability.
[0049] Example 7:
[0050] This embodiment provides a medical device clamp that can prevent interference and quickly change shape. In addition to the technical solution of the above embodiment, it also has the following technical features: gear 1 20, gear 2 21 and gear 3 22 are all rotatably connected to the movable groove 16, gear 2 21 and gear 3 22 mesh with each other, and the output shaft of drive motor 2 23 is rotatably connected to the mounting plate 11.
[0051] Specifically, it ensures that gear 1 20, gear 2 21, and gear 3 22 can rotate normally within the movable slot 16, ensures the structural stability of gear 2 21 and gear 3 22, and ensures that the output shaft of drive motor 2 23 can rotate normally within the mounting plate 11.
[0052] Example 8:
[0053] This embodiment provides a medical device clamp that can prevent interference and allow for rapid changeover. In addition to the technical solutions of the above embodiments, it also has the following technical features: the bottom end of the internal hex bolt 12 is threadedly connected to the turntable 10, and the turntable 10 is plugged into the mounting plate 11.
[0054] Specifically, ensure that the internal hex bolt 12 can be screwed into the turntable 10, and ensure that the turntable 10 can be inserted into the mounting plate 11.
[0055] Working principle: The mounting plate 11 is fixed to the turntable 10 and the mounting plate 11 by the cooperation of the hex bolt 12 with the turntable 10. The mounting plate 11 and the turntable 10 are pre-positioned by a plug-in connection and then fastened by the hex bolt 12. The bottom end of the hex bolt 12 is threaded to the turntable 10, which firmly fixes the mounting plate 11 to the side of the turntable 10. When it is necessary to replace the gripper 17 to adapt to different shapes and sizes of medical devices, the operator only needs to use an Allen wrench to loosen the hex bolt 12 to release the fixing constraint between the mounting plate 11 and the turntable 10. The mounting plate 11 and the two grippers 17 on it can then be pulled out of the turntable 10. After replacing the mounting plate 11 with the corresponding specification of gripper 17, the new mounting plate 11 is inserted into the corresponding interface of the turntable 10, and the hex bolt 12 is tightened again to complete the entire changeover operation. This process does not require disassembling the core components of the clamp, such as the lifting and driving mechanism. The changeover time is short and the operation is simple, realizing the rapid switching of different grippers 17. The opening and closing action of the gripper 17 is driven by the power component. After the drive motor 23 starts, its output shaft drives the gear 21 to rotate synchronously. The gear 21 meshes with the gear 32 and one of the gears 10 at the same time, causing the gear 32 to rotate in the opposite direction with the gear 10. The gear 32 then meshes with the other gear 10, causing it to rotate synchronously in the opposite direction. The two gears 10 mesh with the racks 19 on the two grippers 17 respectively, converting the rotational motion of the gears into the linear reciprocating motion of the racks 19, thereby driving the two grippers 17 to move synchronously closer or further away from each other on the mounting plate 11, realizing the clamping and releasing action of the medical device. The side of the gripper 17 that contacts the medical device is provided with anti-slip texture 18, which can effectively increase the clamping friction and prevent the medical device from sliding or falling off during clamping or adjustment, thus improving the clamping stability. The clamping angle of the gripper 17 is adjusted by the drive assembly. Rotating the knob 24 on the side of the fixed block 26 drives the worm 15 to rotate in the drive groove 13. The worm 15 meshes with the worm wheel 14, converting the rotational motion of the worm 15 into the rotational motion of the worm wheel 14. Since one end of the worm wheel 14 is coaxially fixedly connected to the turntable 10, the rotation of the worm wheel 14 will drive the turntable 10 to rotate synchronously, thereby driving the mounting plate 11 and the two grippers 17 to rotate 360 degrees around the axis of the turntable 10, realizing arbitrary adjustment of the clamping angle of the gripper 17. At the same time, the worm wheel 14 and worm 15 transmission structure has a self-locking characteristic. After the adjustment is completed, the gripper 17 can be stably maintained at the set angle and will not deflect due to clamping force or external force, ensuring the accuracy of the clamping posture. The clamping height of the gripper 17 is adjusted by the lifting assembly. The drive motor 9 is installed in the groove 25 inside the support rod 5. After the drive motor 9 is started, its output shaft drives the threaded rod 8 to rotate in the lifting groove 6. The threaded rod 8 is threadedly connected to the lifting rod 7, which converts the rotational motion of the threaded rod 8 into the linear lifting motion of the lifting rod 7. The lifting rod 7 slides up and down along the lifting groove 6, which drives the fixed block 26 fixedly connected to its top to rise and fall synchronously. The fixed block 26 drives the gripper 17 to adjust its overall height through the turntable 10 and the mounting plate 11. This can adapt to medical devices of different heights and sizes as well as different operating station requirements, avoiding clamping interference problems caused by unsuitable height. The entire fixture can be rotated 360 degrees in the horizontal plane. The rotating disk 3 is rotatably installed in the rotating groove 2 on the top of the base 1. Several protrusions 4 are fixedly installed on the periphery of the rotating disk 3, which makes it easy for the operator to manually apply force to rotate the rotating disk 3. When the rotating disk 3 rotates, it will drive the support rod 5 fixed on its top and all the components above the support rod 5 to rotate around the axis of the base 1, realizing the all-round position adjustment of the gripper 17 in the horizontal plane. This function further expands the working range of the fixture, which can flexibly avoid the interference area of surrounding equipment and instruments, and meet the clamping needs under complex working conditions.
