Description

Technical Field

[0001] The invention relates to the technical field of needle knife processing, and more specifically, to a stable transmission system fixture device for special grinding of needle knives. Background Art

[0002] The needle knife is a surgical instrument consisting of a long needle and a sharp blade, usually used in areas that require fine cutting and suturing during surgery; it can be manually operated or electric; the principle of the needle knife has been widely used in traditional Chinese medicine, acupuncture, massage, and other fields, and has been increasingly recognized and applied in modern medicine.

[0003] At present, the technology of needle knives itself is very mature at present, but there are areas that need to be improved in the existing batch grinding processing. For example, batch grinding of needle knives requires a continuous and stable systematic transmission structure to ensure stable and high-quality batch grinding of needle knives; in the existing batch grinding processing technology, for example, a Chinese patent for a special grinding tool for a medicine feeding needle knife and a batch grinding processing method thereof (authorization announcement number CN110052927B) uses a "half mold" to clamp the needle knives in batches side by side. After the needle knives in this unit "half mold" are ground, they need to be replaced and clamped with a new batch of needle knives, and a truly continuous and stable systematic transmission structure cannot be provided.

[0004] Therefore, in order to solve the above problems, a stable transmission system fixture device for needle knife grinding is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings in the prior art: batch grinding of needle knives requires a continuous and stable systematic transmission structure to ensure stable and high-quality batch grinding of needle knives, and a stable transmission systematic fixture device for special grinding of needle knives is proposed.

[0006] The specific technical solution is as follows: a stable transmission system fixture device for special grinding of acupuncture needles, including a fixture transmission component inserted and installed on a special grinding box for acupuncture needles. The fixture transmission component is used to continuously and stably transport the acupuncture needles into the special grinding box for acupuncture needles, and grind them using a grinding wheel installed inside the special grinding box for acupuncture needles. The fixture transmission component includes an outer protective part and a fixture conveyor belt group. The outer protective part covers the outside of the fixture conveyor belt group and is used for limit protection when contacting the fixture conveyor belt group. The fixture conveyor belt group includes a transmission structure and multiple acupuncture needle fixture parts. The transmission structure includes an upper conveyor belt and a lower conveyor belt distributed in parallel. The acupuncture needle fixture parts are erected between the upper conveyor belt and the lower conveyor belt, and multiple acupuncture needle fixture parts are evenly distributed along the upper conveyor belt and the lower conveyor belt. During the synchronous rotation of the upper conveyor belt and the lower conveyor belt, multiple acupuncture needle fixture parts are driven to enter the special grinding box for acupuncture needles in sequence to grind the acupuncture needles, and then the acupuncture needles are transported out of the special grinding box for acupuncture needles in sequence. The acupuncture needle fixture part includes a placement frame and an acupuncture needle fixture. The acupuncture needle fixture is arranged inside the placement frame and is used to hold the acupuncture needles. The placement frame is arranged between the upper conveyor belt and the lower conveyor belt and is fixedly connected to both of them.

[0007] In view of the areas that need to be improved in the existing batch grinding process, for example, a continuous and stable systematic transmission structure is required for batch grinding of acupuncture needles to ensure stable and high-quality batch grinding of acupuncture needles. In the present invention, the upper conveyor belt and the lower conveyor belt included in the transmission structure are synchronously and intermittently rotated. After the intermittent stop, the acupuncture needles are sequentially placed inside the acupuncture needle fixtures. After continuing to rotate, the placement frames on the acupuncture needle fixture parts drive the acupuncture needle fixtures to enter the special grinding box for acupuncture needles in sequence to grind the acupuncture needles. After the acupuncture needles are ground, they are then transported out of the special grinding box for acupuncture needles in sequence. This provides a continuous and stable systematic transmission structure for batch grinding of acupuncture needles, ensuring stable and high-quality batch grinding of acupuncture needles.

[0008] In the technical solution of the present invention, an operation table is provided at the front end of the special grinding box for acupuncture needles. One end of the outer protective part and the fixture conveyor belt group are both installed on the operation table, and the other end of each penetrates into the special grinding box for acupuncture needles. A lighting ceiling plate is installed on the top of the special grinding box for acupuncture needles above the operation table. A support table plate is installed on the side of the special grinding box for acupuncture needles, and an operation panel is installed on the support table plate. The special grinding box for acupuncture needles is installed on an equipment box body.

[0009] In the technical solution of the present invention, the outer protective part includes a belt and belt rollers. The belt is sleeved outside the transmission structure and is pressed against the outside of multiple acupuncture needle fixture parts. The belt rollers are located at the ends of the belt and are used to drive the belt and the transmission structure to rotate synchronously.

[0010] Further, the upper conveyor belt and the lower conveyor belt adopt the same structure. The upper conveyor belt includes a conveyor belt body and two gears. A driving groove is provided inside the conveyor belt body, and a driving chain is laid inside the driving groove. The two gears are distributed at both ends of the conveyor belt body and are engaged with the driving chain.

[0011] Furthermore, the upper conveyor belt and the lower conveyor belt are synchronously driven through a transmission shaft. The transmission shaft is fixed on the gear, and the gear and the transmission shaft are on the same cylindrical center line. A plurality of steel wires are laid horizontally and vertically in a staggered manner inside both the conveyor belt body and the belt, and the steel wires are used to enhance the traction drive of the conveyor belt body and the belt.

[0012] Therefore, in the technical solution of the present invention, a plurality of electric telescopic rods are additionally installed on the needle scalpel clamp. One end of the electric telescopic rod is fixed on the needle scalpel clamp, and the other end is fixed inside the placement frame. After the needle scalpel is placed inside the needle scalpel clamp, start the telescopic adjustment of the plurality of electric telescopic rods to complete the adjustment of the position of the needle scalpel clamp inside the placement frame, and realize the adjustment of the distance between the plurality of needle scalpel clamps, so as to flexibly adapt to the grinding environment.

[0013] In the technical solution of the present invention, the needle scalpel clamp includes a plurality of first-level locking members and a plurality of second-level locking members, and the plurality of first-level locking members and the plurality of second-level locking members are distributed on the same straight line.

[0014] Further, the first-level locking member includes a plurality of unit clamping plates, and the plurality of unit clamping plates are independently arranged; the plurality of unit clamping plates are arranged in a circular array; a slider is respectively arranged at the ends of the unit clamping plate, and a spring is connected to the slider; a magnetic adsorption convex edge is arranged on one side of the unit clamping plate, and a magnetic adsorption storage groove is arranged on the other side of the unit clamping plate.

[0015] Furthermore, the second-level locking member includes a cylinder body and an inner adaptive locking member, and the inner adaptive locking member is arranged inside the cylinder body; a plurality of sliding grooves are respectively arranged at the ends of the cylinder body, and the plurality of sliding grooves are arranged in a circular array at the end of the cylinder body; the plurality of sliding grooves and the plurality of unit clamping plates are in one-to-one correspondence; the slider is slidably assembled inside the sliding groove, and the spring is connected inside the sliding groove.

[0016] When the needle scalpel is placed between the plurality of unit clamping plates, the magnetic adsorption of the magnetic adsorption convex edge and the magnetic adsorption storage groove is used to complete the mutual approach, tighten and lock the needle scalpel from all around, so as to provide clamping force from multiple points all around, limit the needle scalpel in all directions, and make the overall limit of the needle scalpel more stable, which is beneficial to ensuring the quality of batch grinding of the needle scalpel.

[0017] The inner adaptive locking member includes an outer cylinder and an elastic inner cylinder. The elastic inner cylinder is inserted inside the outer cylinder. A sealing cavity is defined between the outer cylinder and the elastic inner cylinder. A plurality of gas injection pipes are communicated with the sealing cavity, and the gas injection pipes are inserted and fixed on the wall of the outer cylinder. A plurality of anti-slip members are arranged inside the sealing cavity, and the plurality of anti-slip members are distributed in an annular array inside the sealing cavity. One end of the anti-slip member is obliquely fixed on the wall of the outer cylinder, and the other end is inserted on the elastic inner cylinder. The anti-slip member includes a plurality of unit anti-slip members arranged side by side. The unit anti-slip member includes a sleeve plate and an inner insertion plate. The sleeve plate is inserted on the elastic inner cylinder, and the inner insertion plate is obliquely fixed on the wall of the outer cylinder and is movably inserted inside the sleeve plate. A cavity is formed between the sleeve plate and the inner insertion plate, and the cavity is communicated with the gas injection pipe through a connecting pipe.

[0018] For the rotating grinding wheel during grinding, it will drive the needle knife to rotate, which will affect the grinding of the medicine storage groove of the needle knife. In the present invention, the gas injection pipe is used to inject gas into the sealing cavity and the cavity. After the sealing cavity expands, the elastic inner cylinder is used to fit on the needle knife. At the same time, after the air pressure in the cavity between the sleeve plate and the inner insertion plate becomes larger, it will push the sleeve plate to abut against the needle knife. Since the anti-slip member is obliquely fixed on the wall of the outer cylinder, it is beneficial to limit the rotation of the needle knife and avoid the situation that the rotating grinding wheel during grinding drives the needle knife to rotate and affects the grinding of the medicine storage groove of the needle knife. Since the anti-slip member is composed of a plurality of unit anti-slip members arranged side by side, it is combined with the elastic inner cylinder to realize a structure adapted to the outer surface of the needle knife, so as to fit more closely on the needle knife and perform adaptive stable limit locking.

[0019] The stable transmission system fixture device for special grinding of the needle knife of the present invention, compared with the prior art, can achieve:

[0020] First, start the upper conveyor belt and the lower conveyor belt included in the transmission structure to rotate synchronously and intermittently. After the intermittent stop, the needle knives are sequentially placed inside the needle knife fixture. After continuing to rotate, the placement frame on the needle knife fixture drives the needle knife fixture to enter the special grinding box for the needle knife for grinding in sequence. After the grinding of the needle knife is completed, the needle knife is then sequentially conveyed out of the special grinding box for the needle knife; it provides a continuous and stable systematic transmission structure for batch grinding of the needle knife, ensuring stable and high-quality batch grinding of the needle knife.

[0021] Second, after the needle knife is placed inside the needle knife fixture, start the telescopic adjustment of a plurality of electric telescopic rods to complete the adjustment of the position of the needle knife fixture inside the placement frame, and realize the adjustment of the distance between the needle knife fixtures of a plurality of needle knife fixture members to flexibly adapt to the grinding environment.

[0022] III. When the small needle knife is placed between multiple unit clamping plates, the magnetic adsorption of the magnetic adsorption convex edge and the magnetic adsorption storage groove is used to complete the mutual approach, and the small needle knife is tightened and locked from all around, so as to provide clamping force from multiple points all around, limit the small needle knife in all directions, and make the overall limit of the small needle knife more stable, which is beneficial to ensuring the quality of batch grinding of the small needle knife; different from a special grinding tool for a medicine-feeding needle small needle knife and its batch grinding processing method in a Chinese patent (authorization announcement number CN110052927B), which clamps the small needle knives in parallel batch from both sides through a "semi-mold", and it is easy to have a support force vacuum area on both sides;

[0023] IV. For the rotating grinding wheel during grinding, it will drive the small needle knife to rotate, which will affect the grinding of the medicine storage groove of the small needle knife; in the present invention, an air injection pipe is used to inject gas into the sealed cavity and the cavity. After the sealed cavity expands, the elastic inner cylinder is attached to the small needle knife. At the same time, after the air pressure in the cavity between the sleeve plate and the inner inserted plate becomes larger, it will push the sleeve plate against the small needle knife. Since the anti-slip member is inclined and fixed on the barrel wall of the outer barrel, it is beneficial to limit the rotation of the small needle knife and avoid the situation that the rotating grinding wheel during grinding drives the small needle knife to rotate and affects the grinding of the medicine storage groove of the small needle knife;

[0024] V. Since the anti-slip member is composed of multiple unit anti-slip members arranged side by side, it is combined with the elastic inner cylinder to adapt to the outer surface structure of the small needle knife, so as to be more closely attached to the small needle knife and perform adaptive stable limit locking.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0047] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 : A stable conveying systematic fixture device for special grinding of needle scalpels, including a fixture conveying assembly 300 inserted and installed on a special grinding box 200 for needle scalpels. The fixture conveying assembly 300 is used to continuously and stably transport the needle scalpels into the special grinding box 200 for needle scalpels, and grind them using a grinding wheel installed inside the special grinding box 200 for needle scalpels;

[0048] It should be added that: the grinding wheel, the fixing method of the grinding wheel, and the driving method of the grinding wheel all belong to the prior art. Their detailed structures can be obtained from existing literature and periodicals, and can also be directly purchased on the market, or the components can be purchased on the market and assembled, etc.; they are not what the present invention intends to protect, so no detailed description is made here and they are not drawn in the drawings;

[0049] Continue to refer to Figure 2 、 Figures 4 - 6 As shown: The fixture conveying assembly 300 includes an outer protective member 310 and a fixture conveyor belt group 320. The outer protective member 310 covers the outside of the fixture conveyor belt group 320 and is used for limit protection when contacting the fixture conveyor belt group 320;

[0050] The clamp conveyor belt group 320 includes a conveying structure 330 and a plurality of needle scalpel clamp members 340. The conveying structure 330 includes an upper conveyor belt 331 and a lower conveyor belt 335 that are arranged in parallel. The needle scalpel clamp members 340 are erected between the upper conveyor belt 331 and the lower conveyor belt 335, and a plurality of needle scalpel clamp members 340 are evenly distributed along the upper conveyor belt 331 and the lower conveyor belt 335. During the synchronous rotation of the upper conveyor belt 331 and the lower conveyor belt 335, a plurality of needle scalpel clamp members 340 are driven to enter the inside of the special grinding box 200 for needle scalpels in sequence to grind the needle scalpels, and then are conveyed out of the special grinding box 200 for needle scalpels in sequence.

[0051] The needle scalpel clamp member 340 includes a placement frame 341 and a needle scalpel clamp 342. The needle scalpel clamp 342 is arranged inside the placement frame 341, and the needle scalpel clamp 342 is used for holding the needle scalpel. The placement frame 341 is erected between the upper conveyor belt 331 and the lower conveyor belt 335 and is fixedly connected to both of them.

[0052] Therefore, in view of the areas that need to be improved in the existing batch grinding process, such as the problem that a continuous and stable systematic conveying structure is required for batch grinding of needle scalpels to ensure stable and high-quality batch grinding of needle scalpels. In the present invention, the upper conveyor belt 331 and the lower conveyor belt 335 included in the conveying structure 330 are driven to rotate synchronously and intermittently. After the intermittent stop, the needle scalpels are sequentially placed inside the needle scalpel clamp 342. After continuing to rotate, the needle scalpel clamp 342 is driven by the placement frame 341 on the needle scalpel clamp member 340 to enter the inside of the special grinding box 200 for needle scalpels in sequence to grind the needle scalpels. After the grinding of the needle scalpels is completed, they are then conveyed out of the special grinding box 200 for needle scalpels in sequence. A continuous and stable systematic conveying structure is provided for batch grinding of needle scalpels, ensuring stable and high-quality batch grinding of needle scalpels.

[0053] In the embodiment of the present invention, as Figure 1 shown: The special grinding box 200 for needle scalpels is provided with an operating table 220 at its front end. One end of the outer protection member 310 and the clamp conveyor belt group 320 are both installed on the operating table 220, and the other end penetrates into the inside of the special grinding box 200 for needle scalpels.

[0054] At the top of the special grinding box 200 above the operating table 220, an illuminating top plate 210 is installed. At the side of the special grinding box 200, a support table plate 110 is installed, and an operation panel 100 is installed on the support table plate 110. The special grinding box 200 for needle scalpels is installed on the equipment box body 400.

[0055] In the embodiment of the present invention, as Figure 3As shown in the figure: The outer protective part 310 includes a belt 3101 and a belt roller 3102. The belt 3101 is sleeved outside the transmission structure 330 and is pressed against the outside of a plurality of needle knife fixture parts 340. The belt roller 3102 is located at the end of the belt 3101 and is used to drive the belt 3101 and the transmission structure 330 to rotate synchronously.

[0056] In the embodiment of the present invention, as Figure 5 shown in the figure: The upper conveyor belt 331 and the lower conveyor belt 335 have the same structure. The upper conveyor belt 331 includes a conveyor belt body 332 and two gears 333. A driving groove is provided inside the conveyor belt body 332, and a driving chain is laid inside the driving groove. The two gears 333 are distributed at both ends of the conveyor belt body 332 and are engaged with the driving chain.

[0057] In the embodiment of the present invention, as Figure 5 shown in the figure: The upper conveyor belt 331 and the lower conveyor belt 335 are synchronously driven through a transmission shaft 334. The transmission shaft 334 is fixed on the gear 333, and the gear 333 and the transmission shaft 334 are on the same columnar center line;

[0058] A plurality of steel wires arranged horizontally and vertically are laid inside both the conveyor belt body 332 and the belt 3101. The steel wires are used to enhance the traction drive performance of the conveyor belt body 332 and the belt 3101.

[0059] It should be added that: The driving mode of the transmission shaft 334 and the gear 333 can be driven by a motor to provide power. It belongs to the prior art, and the detailed structure can be obtained from existing literature and periodicals. At the same time, it can also be directly purchased on the market, or parts can be purchased on the market for assembly, etc. It is not what the present invention intends to protect, so it will not be elaborated in detail here and is not shown in the drawings.

[0060] Regarding the Chinese patent "A special grinding tooling for feeding needle knives and its batch grinding processing method" (authorization announcement number CN110052927B), the needle knives are clamped side by side in batches through a "semi-mold". However, during the batch grinding process of the needle knives placed side by side in batches, they are too close to each other, and the specifications of the grinding wheels will cause interference between multiple needle knives:

[0061] Therefore, in the embodiment of the present invention, as Figure 6 and Figure 7 shown in the figure: A plurality of electric telescopic rods 343 are installed on the needle knife fixture 342. One end of the electric telescopic rod 343 is fixed on the needle knife fixture 342, and the other end is fixed inside the placement frame 341.

[0062] Therefore, after the needle knife is placed inside the needle knife clamp 342, start the telescopic adjustment of multiple electric telescopic rods 343 to complete the adjustment of the position of the needle knife clamp 342 inside the placement frame 341, and realize the adjustment of the distance between the multiple needle knife clamps 340 and between the needle knife clamps 342 to flexibly adapt to the grinding environment.

[0063] In the embodiment of the present invention, as Figure 7 shown: The needle knife clamp 342 includes a plurality of first-level locking members 344 and a plurality of second-level locking members 345, and the plurality of first-level locking members 344 and the plurality of second-level locking members 345 are distributed on the same straight line.

[0064] At the same time, the distribution modes of the plurality of first-level locking members 344 and the plurality of second-level locking members 345 can be alternately distributed in sequence, or can be divided into multiple places, and then a plurality of first-level locking members 344 and a plurality of second-level locking members 345 in one place are alternately distributed in sequence, or can also be disorderly distributed, etc. There is no limitation on how to distribute specifically, as long as it can satisfy that the plurality of first-level locking members 344 and the plurality of second-level locking members 345 are distributed on the same straight line.

[0065] In the embodiment of the present invention, as Figures 8 - 11 shown: The first-level locking member 344 includes a plurality of unit clamping plates 3441, and the plurality of unit clamping plates 3441 are independently arranged from each other; the plurality of unit clamping plates 3441 are distributed in a circular array; at the ends of both ends of the unit clamping plate 3441, a slider 3443 is respectively arranged, and a spring 3442 is connected to the slider 3443; a magnetic adsorption convex edge 3444 is arranged on one side of the unit clamping plate 3441, and a magnetic adsorption receiving groove 3445 is opened on the other side of the unit clamping plate 3441.

[0066] Regarding the magnetic adsorption function of the magnetic adsorption convex edge 3444 and the magnetic adsorption receiving groove 3445, an electromagnetic coil can be laid, and by energizing and de-energizing the electromagnetic coil, the magnetic adsorption convex edge 3444 and the magnetic adsorption receiving groove 3445 have magnetism and the magnetism is released, which belongs to the prior art. Its detailed structure can be known from existing literature and periodicals, and can also be directly purchased on the market, or parts can be purchased on the market for composition, etc.; it is not what the present invention intends to protect, and will not be elaborated in detail here and is not drawn in the drawings.

[0067] In the embodiment of the present invention, as Figure 12As shown in the figure: The secondary locking member 345 includes a cylinder body 3451 and an inner adaptable locking member 3453, and the inner adaptable locking member 3453 is arranged inside the cylinder body 3451; a plurality of sliding grooves 3452 are respectively formed at the ends of both ends of the cylinder body 3451, and the plurality of sliding grooves 3452 are annularly arrayed at the ends of the cylinder body 3451; the plurality of sliding grooves 3452 and the plurality of unit clamping plates 3441 are in one-to-one correspondence; the slider 3443 is slidably assembled inside the sliding groove 3452, and the spring 3442 is connected inside the sliding groove 3452.

[0068] When the needle knife is placed between the plurality of unit clamping plates 3441, the magnetic adsorption of the magnetic adsorption convex edge 3444 and the magnetic adsorption receiving groove 3445 is used to complete the mutual approach, and the needle knife is tightened and locked from all around (for the detailed process, please refer to Figures 9 to 8 the demonstration process), so as to realize the provision of clamping force from multiple points all around, limit the needle knife in all directions, and the overall limit of the needle knife is more stable, which is beneficial to ensuring the quality of batch grinding of the needle knife; different from a special grinding tooling for a feeding needle knife and its batch grinding processing method in a Chinese patent (the authorized announcement number is CN110052927B), which clamps the needle knives side by side in batches from both sides through a "semi-mold", it is easy to have a support force vacuum area on both sides;

[0069] During the process of the plurality of unit clamping plates 3441 approaching each other, the slider 3443 will slide and move inside the sliding groove 3452 and stretch the spring 3442. After the magnetic adsorption between the magnetic adsorption convex edge 3444 and the magnetic adsorption receiving groove 3445 is released, the spring 3442 will reset to complete the outward expansion of the plurality of unit clamping plates 3441 for the discharge of the needle knife or reloading.

[0070] In the embodiment of the present invention, as Figures 13 - 15 shown in the figure: The inner adaptable locking member 3453 includes an outer cylinder 3455 and an elastic inner cylinder 3457. The elastic inner cylinder 3457 is inserted inside the outer cylinder 3455, and a sealing cavity is defined between the outer cylinder 3455 and the elastic inner cylinder 3457. A plurality of air injection pipes 3454 are communicated with the sealing cavity, and the air injection pipes 3454 are inserted and fixed on the cylinder wall of the outer cylinder 3455;

[0071] A plurality of anti-slip members 3456 are arranged inside the sealing cavity, and the plurality of anti-slip members 3456 are annularly arrayed inside the sealing cavity; one end of the anti-slip member 3456 is obliquely fixed on the cylinder wall of the outer cylinder 3455, and the other end is inserted on the elastic inner cylinder 3457;

[0072] The anti-slip part 3456 includes a plurality of unit anti-slip parts 3458, and the plurality of unit anti-slip parts 3458 are arranged side by side; the unit anti-slip part 3458 includes a sleeve plate 34581 and an inner insertion plate 34582, the sleeve plate 34581 is inserted into the elastic inner cylinder 3457, the inner insertion plate 34582 is obliquely fixed on the cylinder wall of the outer cylinder 3455, and the inner insertion plate 34582 is movably inserted into the sleeve plate 34581; a cavity is formed between the sleeve plate 34581 and the inner insertion plate 34582, and the cavity is connected to the gas injection pipe 3454 through a connecting pipe.

[0073] The rotating grinding wheel for grinding will drive the needle knife to rotate, thereby affecting the grinding of the needle knife medicine storage tank; the present invention uses the gas injection pipe 3454 to inject gas into the sealing cavity and the cavity, and the elastic inner cylinder 3457 is used to fit the needle knife after the sealing cavity expands. At the same time, after the cavity air pressure between the sleeve plate 34581 and the inner insertion plate 34582 becomes larger, the sleeve plate 34581 will be pushed against the needle knife. Since the anti-slip part 3456 is tilted and fixed on the wall of the outer cylinder 3455, it is beneficial to limit the rotation of the needle knife, so as to avoid the situation that the rotating grinding wheel for grinding will drive the needle knife to rotate and affect the grinding of the needle knife medicine storage tank;

[0074] Since the anti-slip part 3456 is composed of a plurality of unit anti-slip parts 3458 arranged side by side, and is further combined with the elastic inner tube 3457, a structure adapted to the appearance of the needle knife is achieved, so that it fits more closely on the needle knife and performs adaptive stable limit locking.
