The reciprocating drive mechanism is arranged on the housing 1 and the power shaft 10, and is used for driving the power shaft 10 to rotate reciprocatingly, so that the milling wheel 5 rolls reciprocatingly along the milling groove 3 to grind medicine.

[0025] In this embodiment, the arc guide plate 6 is fixedly installed in the box body 1 to ensure that its arc is consistent with the arc of the mill groove 3. The arc sleeve 7 is slidably mounted on the arc guide plate 6, and the clamping shaft seat 8 is installed on the arc sleeve 7 through an adaptive connection mechanism. The mill shaft 4 is detachably installed on the clamping shaft seat 8 to ensure that the mill shaft 4 can rotate on the clamping shaft seat 8 but does not fall off. When cleaning, the mill shaft 4 and the mill wheel 5 are removed.

[0026] During grinding, the reciprocating drive mechanism is started to drive the power shaft 10 to reciprocate. The power shaft 10 drives the driving toothed disc 11 to rotate, and the driving toothed disc 11 meshes with the tooth set 9, so that the clamping shaft seat 8 slides along the arc guide plate 6, thereby driving the grinding shaft 4 and the grinding wheel 5 to reciprocate along the track of the grinding groove 3 to grind the Chinese medicine.

[0027] In this solution, the arc guide plate 6 and the arc sleeve 7 cooperate to ensure that the grinding wheel 5 moves accurately along the arc track of the grinding groove 3, so that the grinding process is more uniform and the grinding effect is improved.

[0028] The reciprocating drive mechanism drives the power shaft 10 to rotate reciprocatingly, driving the grinding wheel 5 to roll reciprocatingly, thereby realizing automatic grinding, significantly improving the grinding efficiency, and reducing the tediousness of manual operation.

[0030] This embodiment realizes efficient and accurate grinding of Chinese medicine through the synergistic effect of the arc guide plate 6, the arc sleeve 7, the clamping shaft seat 8, the tooth set 9, the power shaft 10, the driving toothed disc 11, the reciprocating drive mechanism and the adaptive connection mechanism. The device not only improves the grinding efficiency, but also ensures the stability of the grinding process and the retention of the medicinal properties through the automatic drive and the adaptive connection mechanism, providing a reliable tool for anti-liver fibrosis experiments, and has important practical value.

The reciprocating rack 15 is meshed with the pinion 12 on the rod 14, the motor 16 is fixedly installed in the box body 1, the driving shaft 17 is fixedly installed on the output shaft of the motor 16, the driving shaft 17 is rotatably connected to a side wall of the box body 1 and extends outside the box body 1, the first connecting rod 18 is eccentrically fixedly installed on the driving shaft 17, the first connecting rod 18 is located on the outer side of the box body 1, and the second connecting rod 19 is hingedly installed on the reciprocating rack 15 and the first connecting rod 18, and is used to drive the reciprocating rack 15 to slide reciprocatingly along the rectangular guide rod 14.

[0032] In this embodiment, the pinion 12 is fixedly sleeved on the power shaft 10 and ensured to be located on the outer side of the housing 1. The fixing seat 13 is fixedly installed on the outer side of the housing 1, and the rectangular guide rod 14 is fixedly installed on the fixing seat 13 so as to extend below the pinion 12. The reciprocating rack 15 is slidably sleeved on the rectangular guide rod 14 and ensured to mesh with the pinion 12. The motor 16 is fixedly installed in the housing 1, and the driving shaft 17 is fixedly installed on the output shaft of the motor 16 so as to be rotatably connected to a side wall of the housing 1 and extend outside the housing 1. The first connecting rod 18 is eccentrically fixedly installed on the driving shaft 17, and the second connecting rod 19 is hingedly installed on the reciprocating rack 15 and the first connecting rod 18.

[0033] Start grinding: Start the motor 16 to drive the driving shaft 17 to rotate. The driving shaft 17 drives the first connecting rod 18 to rotate eccentrically, and drives the reciprocating rack 15 to slide back and forth along the rectangular guide rod 14 through the second connecting rod 19. The reciprocating rack 15 drives the pinion 12 to rotate back and forth, and then drives the power shaft 10 to rotate back and forth, so that the grinding wheel 5 rolls back and forth along the track of the grinding groove 3 to grind the Chinese medicine.

[0034] Through the cooperation of the pinion 12, the reciprocating rack 15, the rectangular guide rod 14, the first connecting rod 18 and the second connecting rod 19, the power shaft 10 can be precisely rotated back and forth, ensuring that the grinding wheel 5 rolls evenly along the track of the grinding groove 3, thereby improving the grinding effect.

[0035] The motor 16 drives the driving shaft 17 to rotate, and the reciprocating rack 15 is realized to slide back and forth through the connecting rod mechanism, thereby driving the grinding wheel 5 to roll back and forth, which significantly improves the grinding efficiency and reduces the tediousness of manual operation.

[0036] The cooperation of the rectangular guide rod 14 and the fixed seat 13 ensures the stable sliding of the reciprocating rack 15 and avoids deviation during the movement. The design of the motor 16 and the connecting rod mechanism is convenient for maintenance and adjustment, and prolongs the service life of the device.

[0037] This embodiment realizes the precise reciprocating rotation of the power shaft 10 through the coordinated action of the pinion 12, the fixed seat 13, the rectangular guide rod 14, the reciprocating rack 15, the motor 16, the driving shaft 17, the first connecting rod 18 and the second connecting rod 19, thereby driving the grinding wheel 5 to roll evenly along the trajectory of the grinding groove 3.

[0038] In a further preferred embodiment of the present invention, the adaptive connection mechanism includes a mounting plate 20, a T-shaped rod 21, a slip ring 22, an adjusting nut 23, an adaptive spring 24, a connecting rod 25, a fixed ear block 26 and a tile seat 27, wherein the mounting plate 20 is fixedly mounted on the top of the arc-shaped sliding sleeve 7, the mounting plate 20 is located below the clamping shaft seat 8, the T-shaped rod 21 is fixedly mounted on the top of the mounting plate 20, the slip ring 22 is slidably sleeved on the T-shaped rod 21, the adjusting nut 23 is threadedly sleeved on the T-shaped rod 21, the adjusting nut 23 is located above the slip ring 22, and the upper half of the T-shaped rod 21 It has a thread for connecting with the adjusting nut 23, the adaptive spring 24 is sleeved on the T-bar 21, and the two ends of the adaptive spring 24 are respectively in conflict with the slip ring 22 and the adjusting nut 23, the connecting rod 25 is fixedly mounted on the slip ring 22 and the axle holder 8, and is used to make the slip ring 22 and the axle holder 8 move synchronously, so that the grinding wheel 5 can adaptively slide and grind medicine in the grinding groove 3, the fixed ear block 26 is fixedly mounted on the side of the axle holder 8, and the tile seat 27 is detachably mounted on the fixed ear block 26 with bolts, and the tile seat 27 is buckled on the grinding shaft 4, and is used to cooperate with the axle holder 8 to rotate and buckle the grinding shaft 4.

[0039] In this embodiment, the adaptive connection mechanism realizes a flexible and stable connection between the rolling shaft 4 and the arc-shaped sliding sleeve 7. Specifically, the mounting plate 20 is fixedly mounted on the top of the arc-shaped sliding sleeve 7, providing a stable support for the T-bar 21. The T-bar 21 passes through the slip ring 22, and the threaded section on the upper part is connected to the adjusting nut 23. The adaptive spring 24 is sleeved on the T-bar 21, and the two ends are respectively in conflict with the slip ring 22 and the adjusting nut 23. This design allows the slip ring 22 to slide on the T-bar 21 and perform adaptive adjustment through the elastic force of the adaptive spring 24. The connecting rod 25 fixes the slip ring 22 and the clamping shaft seat 8 to ensure the synchronous movement of the two. At the same time, the fixed ear block 26 is installed on the side of the clamping shaft seat 8, and the tile seat 27 is detachably mounted on the fixed ear block 26 by bolts, which is buckled on the rolling shaft 4 and rotates and buckles the rolling shaft 4 together with the clamping shaft seat 8.

[0040] The design of the adaptive connection mechanism enables the grinding shaft 4 and the grinding wheel 5 to adaptively adjust their positions during the grinding process, ensuring that the grinding wheel 5 rolls and grinds the medicine according to the size of the medicine. The elastic force of the adaptive spring 24 enables the slip ring 22 to be fine-tuned up and down according to the force of the grinding shaft 4, thereby maintaining the contact between the grinding wheel 5 and the medicine in the grinding groove 3, improving the uniformity and efficiency of grinding. In addition, the preload of the adaptive spring 24 can be conveniently adjusted by adjusting the nut 23 to adapt to Chinese medicine materials of different hardness and particle size, further enhancing the applicability and flexibility of the equipment.

[0041] The matching design of the tile seat 27 and the clamping shaft seat 8 not only realizes the stable support and rotational engagement of the milling shaft 4, but also facilitates the disassembly and maintenance of the milling shaft 4 and the milling wheel 5. When the milling wheel 5 needs to be cleaned or replaced, the milling shaft 4 and the milling wheel 5 can be easily removed by loosening the bolts on the tile seat 27, which greatly simplifies the operation process. At the same time, the detachable design of the tile seat 27 also facilitates the replacement of the milling wheel 5 of different specifications or materials according to actual needs to meet the grinding requirements of different traditional Chinese medicine materials. This design not only improves the ease of use and maintainability of the equipment, but also provides users with more choices and flexibility.

[0042] In summary, the adaptive connection mechanism of the present invention realizes a flexible and stable connection between the rolling shaft 4 and the arc-shaped sliding sleeve 7 through ingenious design, thereby improving the uniformity and efficiency of grinding, while facilitating the disassembly, assembly and maintenance of the rolling shaft 4 and the rolling wheel 5, and providing users with more choices and flexibility.

[0043] In a further preferred embodiment of the present invention, a limiting ring 28 is rotatably sleeved on the rolling shaft 4 , and the limiting ring 28 contacts the side of the tile seat 27 to limit the position of the rolling shaft 4 .

[0044] In this embodiment, a limiting ring 28 is rotatably mounted on the roller shaft 4. The limiting ring 28 contacts the side of the tile seat 27 to form an effective limiting structure. Such a design not only ensures the stability of the position of the roller shaft 4 during rotation, but also avoids the problem of uneven grinding caused by the shaking of the roller shaft 4. The installation position of the limiting ring 28 is closely matched with the side of the tile seat 27, so that the roller shaft 4 can keep moving on a predetermined track when subjected to external force, thereby ensuring the grinding effect and the stability of the equipment.

[0045] During the grinding process, the grinding shaft 4 and the grinding wheel 5 on it need to withstand the reaction force from the Chinese medicinal materials, which may cause a slight shake of the grinding shaft 4. However, with the restriction of the limit ring 28, the shaking of the grinding shaft 4 is effectively suppressed, thereby ensuring that the grinding wheel 5 can always roll closely in the track of the grinding groove 3. This not only improves the uniformity and efficiency of grinding, but also extends the service life of the equipment and reduces wear and failure caused by shaking.

[0046] In a further preferred embodiment of the present invention, a shaft placement groove is provided on the top of the shaft holder 8 for receiving the roller shaft 4, and a bearing is provided at the engaging position between the roller shaft 4, the shaft holder 8 and the shoe seat 27.

[0047] In this embodiment, a shaft placement groove is provided at the top of the shaft holder 8. This design enables the roller shaft 4 to be placed in the shaft holder 8 more conveniently and accurately, and then engaged with the tile holder 27. At the same time, in order to ensure the smoothness and stability of the roller shaft 4 during rotation, bearings are installed at the engaging positions of the roller shaft 4, the shaft holder 8 and the tile holder 27. The introduction of the bearings not only reduces the friction resistance during rotation, but also improves the rotation accuracy and life of the roller shaft 4. With such a design, the roller shaft 4 can rotate stably and smoothly between the shaft holder 8 and the tile holder 27, thereby driving the roller wheel 5 to perform efficient grinding operations.

[0048] In a further preferred embodiment of the present invention, the arc-shaped sliding sleeve 7 and the reciprocating rack 15 are provided with displacement openings for inserting the arc-shaped guide plate 6 and the rectangular guide rod 14 respectively.

[0049] In this embodiment, the displacement opening on the arc-shaped sleeve 7 is used for inserting the arc-shaped guide plate 6, and the displacement opening on the reciprocating rack 15 is used for inserting the rectangular guide rod 14. Such a design enables the arc-shaped guide plate 6 and the rectangular guide rod 14 to form a stable guiding and connecting relationship with the arc-shaped sleeve 7 and the reciprocating rack 15, respectively. During the grinding process, the arc-shaped guide plate 6 slides along the displacement opening of the arc-shaped sleeve 7, and the rectangular guide rod 14 reciprocates in the displacement opening of the reciprocating rack 15, and together drives the grinding shaft 4 and the grinding wheel 5 to perform grinding operations according to a predetermined trajectory.

[0050] In a further preferred embodiment of the present invention, closing plates are fixedly installed on both sides of the bottom of the medicine grinding seat 2 to prevent the medicine from falling under the box body 1, and the closing plates avoid the driving gear disc 11.

[0051] In this embodiment, closing plates are fixedly installed on both sides of the bottom of the medicine grinding base 2. The main function of these closing plates is to shield the medicine and prevent it from falling under the box body 1 during the grinding process, thereby keeping the grinding area clean and tidy and avoiding the waste of medicine. At the same time, the design of the closing plates also cleverly avoids the position of the driving gear disc 11, ensuring that the driving gear disc 11 can rotate normally and drive the reciprocating rack 15 to reciprocate.

[0052] In a further preferred embodiment of the present invention, each of the shoe seats 27 corresponds to two fixed ear blocks 26, and the inner sides of the shaft seat 8 and the shoe seat 27 are both made of wear-resistant metal.

[0053] In this embodiment, each tile seat 27 now corresponds to two fixed lugs 26. This design not only enhances the stability of the tile seat 27, but also enables the tile seat 27 to be more firmly buckled on the milling shaft 4. At the same time, wear-resistant metal is selected as the inner material of the shaft holder 8 and the tile seat 27. This material has good wear resistance and corrosion resistance, and can effectively extend the service life of the equipment. Through this design, the connection between the tile seat 27 and the shaft holder 8 is more stable and can resist the friction and wear generated during the grinding process.

The solution chamber 29 is opened in the medicine grinding seat 2, and the solution chamber 29 is located below the grinding groove 3, which is used to cool the inner wall of the grinding groove 3 to avoid the influence of high temperature when the medicine is crushed. The liquid infusion pipe 30 is fixedly installed on the medicine grinding seat 2, and the liquid infusion pipe 30 is connected with the solution chamber 29. The liquid inlet end of the liquid infusion pipe 30 extends to the outside of the box body 1 and is provided There is a valve, the cooling box 31 is fixedly installed in the box body 1 and is located below the medicine grinding seat 2, the water inlet pipe 32 connects the solution cavity 29 and the cooling box 31, the return pipe 33 is connected to the cooling box 31, the discharge end of the return pipe 33 extends into the solution cavity 29 and is connected to the water pump 34, the water pump 34 is installed in the solution cavity 29, the heat dissipation pipe 35 is fixedly penetrated in the box body 1 and the cooling box 31, the heat dissipation pipe 35 is immersed in the solution in the cooling box 31, both ends of the heat dissipation pipe 35 are opened and located outside the box body 1, and are used for ventilating and cooling the solution in the cooling box 31.

[0057] In this embodiment, the medicine grinding cooling mechanism includes a solution chamber 29, a liquid replenishing pipe 30, a cooling box 31, a water inlet pipe 32, a water return pipe 33, a water pump 34 and a heat dissipation pipe 35. The solution chamber 29 is opened in the medicine grinding seat 2 and is located below the grinding groove 3, and is used to cool the inner wall of the grinding groove 3 to prevent the medicine from being affected by high temperature during the grinding process. The liquid replenishing pipe 30 is connected to the solution chamber 29 and is used to replenish the cooling liquid in the solution chamber 29. The cooling box 31 is fixedly installed in the box body 1 and is located below the medicine grinding seat 2, and is used to store and cool the required cooling liquid. The water inlet pipe 32 and the water return pipe 33 are respectively connected to the solution chamber 29 and the cooling box 31 to form a circulation loop of the cooling liquid. The water pump 34 is installed in the solution chamber 29 to drive the circulation of the cooling liquid. The heat dissipation pipe 35 runs through the box body 1 and the cooling box 31, and is immersed in the solution in the cooling box 31. Both ends of the heat dissipation pipe 35 are opened and located outside the box body 1, and are used for ventilation cooling of the solution in the cooling box 31.

[0058] The introduction of the medicine grinding cooling mechanism significantly improves the use effect of the device. During the medicine grinding process, a large amount of heat is generated due to friction and extrusion, resulting in an increase in the temperature of the inner wall of the grinding groove 3. High temperature may affect the quality and grinding effect of the medicine. By adding a medicine grinding cooling mechanism, the inner wall of the grinding groove 3 can be effectively cooled to prevent the medicine from being affected by high temperature. At the same time, the design of the liquid infusion tube 30 makes it easy to replenish the coolant to ensure the continuity and stability of the cooling effect.

[0059] In addition, the medicine grinding cooling mechanism also has a good circulation cooling effect. The water inlet pipe 32 and the water return pipe 33 connect the solution chamber 29 and the cooling box 31 to form a circulation loop of the coolant. The water pump 34 drives the coolant to circulate in the loop, taking away the heat from the inner wall of the grinding groove 3, and dissipating the heat to the air outside the box 1 through the heat dissipation pipe 35. This circulation cooling method not only improves the cooling efficiency, but also reduces energy consumption. At the same time, the design of the heat dissipation pipe 35 enables the solution in the cooling box 31 to be fully ventilated and cooled, further improving the cooling effect. These beneficial effects together enable the grinding equipment of the present invention to maintain a stable temperature during the medicine grinding process, ensuring the quality and grinding effect of the medicine.

[0060] In another embodiment of the present invention, a plurality of heat dissipation fins 36 are fixedly mounted on the heat dissipation tube 35, and the plurality of heat dissipation fins 36 are evenly distributed in a circular array along the heat dissipation tube 35, and the heat dissipation fins 36 are located in the cooling box 31, and one section of the heat dissipation fins 36 is located in the cooling box 31, and the other section is located in the heat dissipation tube 35 to achieve heat exchange, and a fan bracket 37 fixedly connected to the outside of the box body 1 is provided on one side of the cooling box 31, and a fan shaft 38 is rotatably mounted on the fan bracket 37, one end of the fan shaft 38 extends into the heat dissipation tube 35 and is fixedly mounted with fan blades 39, and a pulley 40 is fixedly mounted on the other end of the fan shaft 38, and a belt pulley 41 is fixedly mounted on the end of the power shaft 10 located outside the box body 1, and a synchronous belt 42 is sleeved on the belt pulley 41 and the pulley 40, and a tensioning shaft 43 is provided on the side of the box body 1 for tensioning the synchronous belt 42.

[0061] In this embodiment, the heat dissipation fins 36 are evenly distributed in a circular array along the heat dissipation tube 35, and are partially located in the cooling box 31, and partially extend into the heat dissipation tube 35 to achieve more effective heat exchange. In addition, a fan bracket 37 is added on one side of the cooling box 31, and a fan shaft 38 is rotatably mounted thereon. One end of the fan shaft 38 extends into the heat dissipation tube 35, and a fan blade 39 is fixedly installed thereon to accelerate the air flow in the heat dissipation tube 35 and improve the heat dissipation effect. A pulley 40 is fixedly installed at the other end, and is connected to the belt pulley 41 on the power shaft 10 through a synchronous belt 42 to achieve synchronous drive of the fan. In order to ensure the tension of the synchronous belt 42, a tensioning shaft 43 is set on the side of the box body 1.

[0062] The introduction of the heat dissipation fins 36 significantly improves the heat dissipation efficiency of the heat dissipation pipe 35. These fins increase the contact area between the heat dissipation pipe 35 and the air, so that the heat can be transferred to the air more quickly. At the same time, part of the fins is located inside the heat dissipation pipe 35, which can more effectively absorb the heat inside the heat dissipation pipe 35, realize internal and external heat exchange, and further improve the heat dissipation effect.

[0063] The combined design of the fan bracket 37, the fan shaft 38, the fan blades 39, the pulley 40, the belt disc 41 and the synchronous belt 42 realizes the synchronous drive of the fan, so that the fan can rotate with the rotation of the power shaft 10 without the need for an additional power source. This design not only simplifies the structure of the device, but also reduces energy consumption. At the same time, the rotation of the fan accelerates the air flow in the heat pipe 35, so that the heat can be dissipated into the air faster, further improving the heat dissipation efficiency. The setting of the tensioning shaft 43 ensures the tension of the synchronous belt 42, avoiding the problem of unstable rotation or stopping of the fan due to loose synchronous belt. These beneficial effects together enable the grinding equipment of the present invention to maintain a stable temperature during long-term operation, ensuring the stability and reliability of the equipment.

[0064] In summary, by optimizing the heat dissipation pipe 35 and adding a fan drive mechanism, the present invention further improves the heat dissipation efficiency of the device and ensures the stability and reliability of the device during long-term operation. These improvements not only improve the performance of the device, but also provide users with a more high-quality and efficient grinding experience.

[0066] In this embodiment, a base plate 44 is added below the box body 1, and two hinged support plates 45 are fixedly installed on the top of the base plate 44. The two hinged support plates 45 are respectively hinged to the two sides of the box body, so that the box body 1 can be flipped around the hinge point, so as to conveniently pour the medicine.

One end of the pull wire 50 is connected to the wire take-up device 49, and the other end passes through the threading port 48 and is fixedly connected to the base plate 44. In this way, when the box body 1 is turned over, the pull wire 50 will be stretched, and a rebound force will be generated through the torsion spring in the wire take-up device 49, thereby limiting the folding angle of the box body 1. In order to ensure the smooth sliding of the pull wire 50, a wire rack 51 is fixedly installed on both sides of the base plate 44.

[0069] The combined design of the threading port 48, the wire take-up device 49 and the wire pull 50 enables the box body 1 to be effectively limited during the flipping process, avoiding equipment damage or safety hazards caused by excessive folding angles. This design not only improves the stability of the equipment, but also protects the safety of the operator. At the same time, the torsion spring in the wire take-up device 49 can automatically reel in the wire pull 50, making the operation more convenient without manual wire retraction.

[0070] In another embodiment of the present invention, a rod seat 52 is fixedly installed on the side of the box body 1, a guide rod 53 is fixedly installed on the rod seat 52 in the longitudinal direction, a handle frame 54 is slidably sleeved on the guide rod 53, a gripping handle 55 is fixedly installed on the handle frame 54, a return spring 56 is sleeved on the guide rod 53, the bottom end of the return spring 56 is in conflict with the handle frame 54, and the top end is in conflict with the rod seat 52, so that the handle frame 54 slides upward along the guide rod 53 to compress the return spring 56, and a mounting is provided on the top inner wall of the threading port 48. A matching groove 57 is provided in which a wire pressing block 58 is slidably installed. The bottom of the wire pressing block 58 is used to press the pull wire 50 for positioning.

The other end of the drawstring 59 slides and extends to the outside of the bottom support seat 46 and is fixedly connected to the handle frame 54, so that when the handle frame 54 slides, the drawstring 59 is used to pull the wire pressing block 58 to move up synchronously to disengage the pull wire 50. A wire pressing spring 60 is provided on the top of the wire pressing block 58, and the top end of the wire pressing spring 60 contacts the top inner wall of the assembly groove 57.

[0071] In this embodiment, a rod seat 52 is fixedly installed on the side of the box body 1, and a guide rod 53 is fixedly installed longitudinally on the rod seat 52. A handle frame 54 is slidably mounted on the guide rod 53, and a gripping handle 55 is fixedly mounted on the handle frame 54, so that the operator can hold it conveniently. At the same time, a reset spring 56 is also sleeved on the guide rod 53, and the bottom end of the reset spring 56 conflicts with the handle frame 54, and the top end conflicts with the rod seat 52, so that the handle frame 54 can compress the reset spring 56 when sliding upward along the guide rod 53. In addition, an assembly groove 57 is opened on the top inner wall of the threading port 48, and a wire pressing block 58 is slidably installed in the assembly groove 57.

In this way, when the medicine needs to be dumped, the gripping handle 55 is held to fold the box body 1. First, the handle frame 54 slides upward, and the pressing block 58 is pulled upward synchronously through the drawstring 59, thereby disengaging the drawstring 50. When the gripping handle 55 is released, the compression spring 60 and the compression reset spring 56 are rebounded, and the pressing block 58 continues to press the drawstring 50, thereby fixing the folding angle of the box body 1. When dumping, the folding angle of the box body 1 is greater than 180°, so it can be fixed.

[0072] The combined design of the guide rod 53, the handle frame 54, the reset spring 56 and the gripping handle 55 enables the operator to conveniently control the sliding of the handle frame 54 by gripping the handle 55, thereby realizing the control of the wire pressing block 58. This design not only improves the convenience of operation of the device, but also enables the operator to adjust the positioning state of the pull wire 50 at any time as needed, thereby improving the flexibility of the device.
