Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a coccyx position adjuster. Background Technology

[0002] Coccyx fractures or sacroiliac joint injuries often result in coccyx alignment abnormalities. When coccyx alignment is abnormal, the misaligned coccyx needs to be realigned. During this process, the doctor inserts their fingers into the patient's anus and moves them to the location of the abnormal coccyx. The doctor then grasps the coccyx and adjusts it using joint mobilization techniques to bring the abnormal coccyx back to its normal position.

[0003] However, during the treatment process, the doctor needs to insert his fingers into the patient's anus, which requires a high level of experience from the doctor. Moreover, the patient's excrement can affect the doctor's operation, making it inconvenient for the doctor and resulting in low treatment efficiency.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] The purpose of this application is to provide a coccyx position adjuster that has the advantage of greatly facilitating the adjustment process of the coccyx without requiring the doctor to insert his fingers into the patient's anus.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] On one hand, this application provides a coccyx position adjuster, comprising:

[0008] A gripper having opposing proximal and distal ends;

[0009] The adjusting joint is movably located at the distal end of the gripper;

[0010] The support is movably mounted on the adjusting joint, and its relative angle with the gripping component is adjusted by connecting the adjusting joint.

[0011] The drive mechanism is housed within the support component;

[0012] A clamping mechanism is connected to the drive mechanism and protrudes from the surface of the support member;

[0013] The clamping mechanism is used to clamp the patient's coccyx and moves back and forth in a preset direction by being driven by the drive mechanism.

[0014] In one embodiment, the support member includes:

[0015] The support rod has an installation cavity inside and a movable slot on its outer wall, which connects to the installation cavity.

[0016] A support connection part is provided at the proximal end of the support rod and is movably connected to an adjustment joint;

[0017] The drive mechanism is located inside the mounting cavity, and the clamping mechanism passes through the moving slot.

[0018] In one embodiment, the drive mechanism includes:

[0019] The drive motor is fixedly installed inside the mounting cavity.

[0020] A first transmission assembly is connected to a drive motor;

[0021] A linear drive assembly is connected to a first transmission assembly and is driven by a drive motor through the first transmission assembly;

[0022] The mobile stage is connected to the linear drive assembly and moves back and forth in a preset direction by being driven by the linear drive assembly.

[0023] In one embodiment, a guide rail component is fixedly disposed within the mounting cavity, and the guide rail component is arranged parallel to the linear drive assembly.

[0024] The guide slide is connected to the moving platform and slides in connection with the guide rail.

[0025] In one embodiment, the clamping mechanism includes:

[0026] A clamping bracket is mounted on the drive mechanism;

[0027] The clamping motor is located on the side of the clamping bracket facing the drive mechanism;

[0028] The second transmission assembly passes through and is rotatably connected to the clamping bracket, and is also connected to the clamping motor.

[0029] The gear is connected to the second transmission assembly and rotates by the drive of the clamping motor;

[0030] Two racks are located on opposite sides of the gear and mesh with both gears;

[0031] Two clamping parts are connected to the racks on both sides respectively;

[0032] The two clamping parts move closer or further apart by the interaction of the gears and the racks on both sides.

[0033] In one embodiment, the clamping portion includes:

[0034] A clamping seat is fixedly connected to the rack in a vertical direction;

[0035] The extension post is fixedly mounted on the clamping seat and extends out as a support member;

[0036] The clamping block is connected to the extension post, and the side facing away from the extension post is set as an arc surface.

[0037] The curved surfaces of the clamps on both sides are used to hold the patient's coccyx.

[0038] In one embodiment, the gripping element includes:

[0039] The grip lever has a cable routing cavity inside.

[0040] The grip connection part is located at the far end of the grip rod and is movably connected to the adjustment joint;

[0041] The handle is located at the proximal end of the grip lever;

[0042] The control switch is located at the end of the grip lever facing the handle. The control switch is electrically connected to the drive mechanism and the clamping mechanism via a cable.

[0043] In one embodiment, the control switch has at least four control positions, each of which is used to drive the drive mechanism to start and move the clamping mechanism. The four control positions drive the clamping mechanism to move at different speeds.

[0044] In one embodiment, the adjusting connector includes:

[0045] The main clamping block is located on one side of the support connection and the gripping connection.

[0046] The movable clamping block is located on the other side of the support connection and the grip connection and is movably connected to the main clamping block. The main clamping block and the movable clamping block are provided with a first spherical hole and a second spherical hole. The support connection and the grip connection are respectively connected to the first spherical hole and the second spherical hole.

[0047] The knob connects the main clamping block and the movable clamping block, and by rotating it, the movable clamping block moves closer to the main clamping block.

[0048] In one embodiment, the coccyx position adjuster further includes a limiting member, the position of which is adjustable along the extension direction of the gripping member and is used to abut against the patient to limit the support member entering the patient's body.

[0049] The beneficial effects of the coccyx position adjuster provided in this application are at least as follows: The structure consisting of a gripper, an adjusting connector, and a support allows for adjustment of the relative positions of the gripper and the support. This allows the angle of the support to be adjusted after it enters the patient's anus, thereby adjusting the clamping angle of the clamping mechanism. Alternatively, the drive mechanism can be activated to adjust the proximal and distal positions of the clamping structure, enabling the clamping mechanism to align with an abnormal coccyx position. By clamping the abnormal coccyx, the drive mechanism is activated to control the back-and-forth movement of the clamping mechanism, thus pushing the coccyx joint to move rhythmically, achieving the normal position of the coccyx and adjusting the abnormal coccyx. During this operation, the doctor holds the gripper outside the patient's anus and clamps the coccyx for adjustment and alignment. This avoids the doctor directly inserting their hand into the patient's anus, which would interfere with the doctor's operation; thus greatly facilitating the doctor's operation and improving treatment efficiency.

Detailed Implementation

[0059] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0060] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it may be directly or indirectly located on that other component. When a component is referred to as "connected to" another component, it may be directly or indirectly connected to that other component. The terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate orientations or positions based on the accompanying drawings, and are for ease of description only, and should not be construed as limiting the technical solution. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.

[0061] like Figure 1 , Figure 2As shown, this embodiment proposes a coccyx position adjuster for clamping and moving an abnormally positioned coccyx of a patient, and adjusting the abnormal coccyx to the correct position. This coccyx position adjuster mainly includes: a gripper 100, an adjustment joint 200, a support 300, a drive mechanism 400, and a clamping mechanism 500. The gripper 100 has opposing proximal and distal ends; for ease of structural description, the gripper 100 is cylindrical and extends axially for a predetermined length, with the end closer to the doctor being the proximal end and the end farther from the doctor being the distal end. The adjustment joint 200 is movably disposed at the distal end of the gripper 100, and its position can be adjusted by rotation at the distal end of the gripper 100. The support 300 is movably disposed on the adjustment joint 200, and the support 300 can be located at the distal end of the adjustment joint 200 and its position can be adjusted by rotation. The adjusting connector 200 can be a universal connector. The relative angle between the support member 300 and the gripping member 100 can be adjusted by connecting the adjusting connector 200. After the support member 300 is inserted into the patient's anus, its angle can be adjusted according to different positions, making this coccyx position adjuster more practical. The drive mechanism 400 is located inside the support member 300, and after activation, it provides driving power to the clamping mechanism 500. The clamping mechanism 500 is connected to the drive mechanism 400 and protrudes from the outer surface of the support member 300. The clamping mechanism 500 has a portion located inside the support member 300 and a portion protruding from the outer surface of the support member 300. After activation, the portion protruding from the outer surface of the support member 300 can clamp the coccyx. Activating the drive mechanism 400 again causes the clamping mechanism 500 to move back and forth along a preset direction while clamping the coccyx. The preset direction is the axis of the support 300. By moving the coccyx joint back and forth, the coccyx is aligned to the correct position.

[0062] The working principle of the coccyx position adjuster provided in this embodiment is as follows: The doctor holds the gripper 100 and, based on the abnormal angle of the patient's coccyx, adjusts the relative position of the groove and the support 300 through the adjusting connector 200. This allows the support 300 to be inserted into the patient's anus, facilitating angle adjustment and thus making the clamping angle of the clamping mechanism 500 adjustable. Activating the drive mechanism 400 moves the clamping mechanism 500 to the abnormal coccyx position by adjusting the distance of the clamping structure. Since the angle of the support 300 is adjustable, the clamping mechanism 500 can be aligned with the abnormal coccyx position. After clamping the abnormal coccyx, the drive mechanism 400 is activated again to control the back-and-forth movement of the clamping mechanism 500, thereby pushing the coccyx joint to move rhythmically to achieve the normal position of the coccyx and adjust the abnormal coccyx. During this operation, the doctor holds the gripper 100 outside the patient's anus and performs the adjustment by clamping and straightening the coccyx. This avoids the doctor having to directly insert their hand into the patient's anus, which would interfere with the doctor's operation; the doctor only needs to control the procedure from outside the patient's body, which greatly facilitates the doctor's operation and improves treatment efficiency.

[0063] like Figure 1 , Figure 2 , Figure 3 As shown, the support member 300 in this embodiment further includes a support rod 310 and a support connecting portion 320. The support rod 310 is a round rod that extends axially for a predetermined length. A mounting cavity 330 is provided inside the support rod 310, extending axially. A movable slot 340 is formed on the outer wall of the support rod 310, extending axially for a predetermined distance and communicating with the mounting cavity 330. The support connecting portion 320 is located at the proximal end of the support rod 310 and is movably connected to an adjusting joint 200. By adjusting the adjusting joint 200, the angle of the support rod 310 can be changed. A drive mechanism 400 is located within the mounting cavity 330, and a clamping mechanism 500 passes through the movable slot 340. A cable routing hole is also provided inside the support rod 310. The cable routing hole passes through the support connection part 320 and connects to the mounting cavity 330. The cable routing hole is used to run a cable and electrically connect the drive mechanism 400 and the clamping structure located in the mounting cavity 330 through the cable.

[0064] By incorporating parts of the drive mechanism 400 and clamping mechanism 500 within the support rod 310, the size of the structure entering the human anus can be effectively reduced, making it easier for the support rod 310 to enter the human anus and optimizing the structure.

[0065] like Figure 2 , Figure 3 , Figure 6As shown, the drive mechanism 400 further includes: a drive motor 410, a first transmission assembly 420, a linear drive assembly 430, and a moving stage 440. The drive motor 410 is fixedly installed in the mounting cavity 330. The drive motor 410 can be arranged along the axial direction of the support rod 310, so that the rotating shaft of the drive motor 410 faces the proximal end. The first transmission assembly 420 is connected to the rotating shaft of the drive motor 410. The drive circuit is activated to drive the first transmission assembly 420 to achieve transmission. The linear drive assembly 430 is connected to the first transmission assembly 420 and is driven by the drive motor 410 through the first transmission assembly 420. In this embodiment, the first transmission assembly 420 includes a reduction gear set. The reduction gear set achieves speed reduction, thereby converting the faster speed of the drive motor 410 into the slower speed of the linear drive assembly 430, and finally controlling the reciprocating movement of the clamping mechanism 500 within a reasonable speed range. The linear drive assembly 430 uses a ball screw assembly 431. The moving stage 440 is connected to the screw nut 432 of the ball screw assembly 431 and moves back and forth in a preset direction driven by the ball screw assembly 431. The reduction gear assembly reduces the rotation of the drive motor 410 and drives the screw of the ball screw assembly 431 to rotate. The screw drives the screw nut 432 to move, thereby driving the moving stage 440 to move axially. Using the ball screw assembly 431 for transmission ensures stable transmission, high movement accuracy, and easy control of the movement distance. This allows for precise control of the tailbone's position when the clamping mechanism 500 moves the tailbone, reducing the risk of accidents due to excessive movement.

[0066] It is easy to imagine that the drive mechanism 400 can also adopt a belt drive structure, electric cylinder, etc.

[0067] like Figure 6 As shown, furthermore, to ensure the smooth movement of the drive mechanism 400, a guide rail component 450 and a guide slide 460 are fixedly installed within the mounting cavity 330. The guide rail component 450 is arranged parallel to the linear drive assembly 430. Figure 4 , Figure 6 As shown, the guide slide 460 is connected to the movable stage 440 and slidably connected to the guide rail component 450. Specifically, guide rail components 450 are provided on both the left and right sides of the linear drive assembly 430, and guide slides 460 are installed on both the left and right sides of the movable stage 440. The guide slides 460 and guide rail components 450 cooperate to slide, thereby guiding the back-and-forth movement of the movable stage 440 and ensuring the smooth movement of the movable stage 440.

[0068] like Figure 4 , Figure 6As shown, the guide rail component 450 in this embodiment may include an L-shaped guide platform 451. The L-shaped guide platform 451 has a horizontal surface 452 and a vertical surface 453 that are perpendicular to each other. A dovetail platform 454 is provided on the horizontal surface 452. The corresponding guide slide 460 includes a slide body 461. The upper surface of the slide body 461 is fixed to the lower surface of the moving platform 440. A dovetail groove 462 is provided on the lower surface of the slide body 461. The dovetail groove 462 is fitted onto the dovetail platform 454. The sliding of the moving platform 440 is guided by the cooperation of the dovetail groove 462 and the dovetail platform 454. The side of the slide body 461 can abut against the vertical surface 453 of the L-shaped guide platform 451, thereby limiting the side of the slide body 461 by the vertical surface 453 of the L-shaped guide platform 451. This prevents the moving platform 440 from swaying left and right, and makes the sliding of the moving platform 440 more stable.

[0069] like Figure 4 , Figure 6 As shown, a triangular platform 455 is further provided on the vertical surface 453 of the L-shaped guide table 451, and a triangular groove 463 is provided on the side of the corresponding slide body 461. Through the cooperation of the triangular platform 455 and the triangular groove 463, more limit positions can be added, requiring the slide body 461 to have higher precision during the processing, and making the moving table 440 more stable.

[0070] It is easy to imagine that the guide rail 450 can use only rectangular guide rails or dovetail guide rails, while the guide slide 460 can use a rectangular slide or a dovetail slide accordingly.

[0071] like Figure 3 , Figure 4 , Figure 5As shown, the clamping mechanism 500 of this embodiment further includes: a clamping bracket 510, a clamping motor 520, a second transmission assembly 530, a gear 540, two racks 550, and two clamping parts 560. The clamping bracket 510 is disposed on the drive mechanism 400. The clamping bracket 510 includes a support column 511 and a support plate 512. The support column 511 connects the support plate 512 to the moving stage 440. A mounting position is formed between the support plate 512 and the moving stage 440. The clamping motor 520 is disposed on the side of the clamping bracket 510 facing the drive mechanism 400, that is, the clamping motor 520 is located in the mounting position and can be fixed on the upper surface of the moving stage 440. A through hole is provided in the middle of the support plate 512. The second transmission component 530 passes through the support plate 512 and is rotatably connected to the through hole via a bearing. The lower end of the second transmission component 530 is connected to the clamping motor 520. After the clamping motor 520 is started, it rotates and drives the second transmission component 530 to rotate. A gear 540 is connected to the second transmission component 530 and rotates by the clamping motor 520. Two racks 550 are located on opposite sides of the gear 540 and mesh with the gear 540. Two clamping parts 560 are connected to the racks 550 on both sides, and both clamping parts 560 protrude from the moving slot 340 and are arranged opposite each other. The two clamping parts 560 move closer or further apart by the engagement of the gear 540 and the racks 550 on both sides. In the specific structure, the second transmission component 530 includes a driving bevel gear 531, a driven bevel gear 532, and a main rotating shaft 533. The driving bevel gear 531 is connected to the rotating shaft of the clamping motor 520, and the driven bevel gear 532 is connected to the lower end of the main rotating shaft 533. The main rotating shaft 533 is connected to the support plate 512 through a bearing, and the upper end of the main rotating shaft 533 extends above the support plate 512 and connects to the gear 540. Through the cooperation of the driving bevel gear 531 and the driven bevel gear 532, the clamping motor 520 is set axially, while the main rotating shaft 533 can be set vertically. This reduces the installation space of the clamping motor 520 and optimizes the structure, allowing the clamping motor 520 and other structures to be installed in a smaller mounting cavity 330.

[0072] After the clamping motor 520 starts and rotates, it drives the second transmission component 530 to rotate. The second transmission component 530 drives the gear 540 to rotate. Through the rotation of the gear 540, the racks 550 located on the left and right sides move towards each other or away from each other, thereby moving the clamping parts 560 on them towards each other to achieve the clamping function of the coccyx, and moving the clamping parts 560 on them away from each other to achieve the releasing function of the coccyx.

[0073] To make the rack 550 move more stably, a row of guide posts 513 are provided on the left and right sides of the support plate 512, and the rack 550 is provided with corresponding waist-shaped holes 551. The waist-shaped holes 551 are fitted on the guide posts 513. Through the limiting of the guide posts 513, the rack 550 can move along the axial direction of the support rod 310 under the drive of the gear 540.

[0074] like Figure 3 , Figure 4 , Figure 5 As shown, the clamping part 560 in this embodiment further includes: a clamping seat 561, an extension post 562, and a clamping block 564. The clamping seat 561 is fixedly connected to the rack 550 and extends perpendicular to the rack 550 towards the other side of the rack 550; the extension post 562 is fixedly disposed on the clamping seat 561, extends upward, and protrudes from the support member 300 towards the moving slot 340. The clamping block 564 is connected to the extension post 562, and the side facing away from the extension post 562 is set as an arc-shaped surface; the arc-shaped surfaces of the two clamping blocks 564 are used to clamp the patient's coccyx. The opposite sides of the two clamping blocks 564 are clamping surfaces, and the arc-shaped clamping surfaces match the shape of the patient's coccyx, thereby achieving stable clamping during the clamping process, and the coccyx will not detach from the two clamping blocks 564.

[0075] like Figure 3 As shown, to further achieve stable support for the clamping seat 561, support grooves 331 are provided on the inner walls of the left and right sides of the mounting cavity 330. The support grooves 331 extend a predetermined length along the axial direction of the support rod 310. In the specific connection process, the clamping seat 561 on the right rack 550 extends to the left and is embedded in the support groove 331 on the left (the same applies to the left side); thus, one end of the clamping seat 561 is fixed to the rack 550, and the other end is located in the support groove 331 for sliding support, thereby providing support points at both ends of the clamping seat 561, which provides stable support for the extended column 562 at the middle position of the clamping seat 561.

[0076] like Figure 4 , Figure 6As shown, further, the clamping block 564 in this embodiment can be configured as a movable clamping block 220. Specifically, a connecting groove 563 is provided at the upper end of the extension post 562. The clamping block 564 is located within the connecting groove 563 and hinged to the extension post 562. The upper end of the clamping block 564 protrudes from the connecting groove 563, allowing the clamping block 564 to rotate at a small angle within the connecting groove 563. An elastic element 565, which can be a spring, is provided between the lower parts of the clamping blocks 564 on both sides. This spring causes the lower parts of the clamping blocks 564 on both sides to move closer together, making the distance between the upper parts of the clamping blocks 564 on both sides greater than the distance between the lower parts of the clamping blocks 564. This better matches the upper-wide, lower-narrow structure of the coccyx. Furthermore, the elastic element 565 reduces the impact on the coccyx during clamping, preventing further damage from strong impacts. The elastic element 565 pushes the clamping block 564 to adaptively clamp coccyx of different sizes, so that the clamping blocks 564 on both sides can adapt to coccyx of different sizes, thus improving practicality.

[0077] like Figure 1 , Figure 7 As shown, the gripping member 100 in this embodiment further includes: a gripping rod 110, a gripping connection part 120, a handle 130, and a control switch 140. The gripping rod 110 adopts a round rod structure with a cable routing cavity inside. The gripping connection part 120 is located at the distal end of the gripping rod 110 and is movably connected to the adjusting connector 200. The cable routing cavity extends through the gripping connection part 120, and the cable can be placed in the cable routing cavity, passing through the adjusting connector 200 and then into the cable routing hole inside the support rod 310. After exiting from the cable routing hole, it connects to the drive motor 410 of the drive mechanism 400 and the clamping motor 520 of the clamping structure. To move with the clamping motor 520, a chain-type movable cable groove is provided inside the mounting cavity 330, through which the cable to be moved is laid. The handle 130 is located at the proximal end of the grip lever 110 for easy gripping by the doctor. The control switch 140 is located at the end of the grip lever 110 facing the handle 130. The control switch 140 is electrically connected to the drive mechanism 400 and the clamping mechanism 500 via a cable.

[0078] Furthermore, the control switch 140 has at least four control positions, each used to control the start of the drive mechanism 400 and move the clamping mechanism 500. The four control positions drive the clamping mechanism 500 at different speeds. The specific settings are as follows:

[0079] The first level is: at the starting point of the patient's coccyx joint movement, move the joint back and forth rhythmically in a small range.

[0080] The second level is: within the patient's permissible range of coccyx joint movement, the joint is moved back and forth rhythmically and extensively, but without touching the beginning and end of the joint movement.

[0081] The third level is: within the patient's permissible range of coccyx joint movement, the joint is moved back and forth rhythmically and extensively, with each movement contacting both the beginning and end of the joint's movement.

[0082] The fourth level is: at the end of the patient's coccyx joint movement, move the joint back and forth rhythmically in a small range, contacting the end of the joint movement each time.

[0083] like Figure 1 , Figure 7 As shown, the adjusting connector 200 in this embodiment further includes a main clamping block 210, a movable clamping block 220, and a knob 230. The main clamping block 210 is located on one side of the support connecting part 320 and the grip connecting part 120, and the movable clamping block 220 is located on the other side of the support connecting part 320 and the grip connecting part 120 and is movably connected to the main clamping block 210. The main clamping block 210 and the movable clamping block 220 are provided with a first spherical hole 211 and a second spherical hole 212. The support connecting part 320 and the grip connecting part 120 are respectively connected to the first spherical hole 211 and the second spherical hole 212. The knob 230 connects the main clamping block 210 and the movable clamping block 220, and by rotating it, the movable clamping block 220 moves closer to the main clamping block 210. In the specific structure, both the support connection 320 and the grip connection 120 are spherical, while the main clamping block 210 and the movable clamping block 220 are located on the left and right sides respectively. By turning the knob 230, the first spherical hole 211 and the second spherical hole 212 can be enlarged or reduced. If enlarged, the support rod 310 and the gripping rod 110 can be loosened, thereby adjusting the angle between the support rod 310 and the gripping rod 110. The spherical mating structure allows for angle adjustment in multiple directions. After the position is adjusted, the holes are reduced to fix the positions of the support rod 310 and the gripping rod 110.

[0084] like Figure 1 , Figure 7 As shown, the coccyx position adjuster in this embodiment further includes a limiting member 600. The limiting member 600 is adjustable in position along the extending direction of the holding member 100 and is used to abut against the patient to limit the support member 300 entering the patient's body. By setting the limiting part, when the support member 300 enters the human body and reaches the position of the abnormal coccyx, the limiting member 600 is adjusted so that it abuts against the patient's buttocks, thus fixing the position of the limiting member 600 on the holding member 100, thereby keeping the support member 300 stationary in the patient's body. Therefore, during the process of adjusting the coccyx, the support member 300 will not easily move, avoiding displacement during the coccyx adjustment process.

[0085] like Figure 7 As shown, further, the limiting member 600 in this embodiment specifically includes: an adjusting sleeve 610 and a limiting plate 620. The adjusting sleeve 610 is slidably sleeved on the gripping rod 110. An adjusting screw 630 is screwed onto the outer wall of the adjusting sleeve 610. The adjusting screw 630 passes through the adjusting sleeve 610 and abuts against the gripping rod 110. By turning the adjusting screw 630, the adjusting sleeve 610 and the gripping rod 110 can be loosened, allowing the adjusting plate 610 to move axially along the gripping rod 110. The limiting plate 620 is also adjustablely connected to the adjusting sleeve 610. A rotating rod is provided at one end of the limiting plate 620. The rotating rod is rotatably mounted on the outer wall of the adjusting sleeve 610. A clamping screw 640 is provided on the outer wall of the adjusting sleeve 610. The clamping screw 640 passes through the adjusting sleeve 610 and abuts against the rotating rod. By turning the clamping screw 640, the rotating rod can be loosened, allowing the limiting plate 620 to rotate axially around the rotating rod. This also allows for the movement and rotation of the limiting plate 620, making it easy to position the limiting plate 620 against different locations to achieve limiting.

[0086] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
