Description

Technical Field

[0001] The invention relates to a veterinary castration instrument, in particular to an electrothermal hemostatic boar castration knife. Background Art

[0002] In the pig farming industry, in order to improve the meat quality of boars and facilitate management, except for a few breeding boars, all other boars need to be castrated. This operation requires high technical skills from workers, and a large number of boars need to be castrated. During the castration process, the testicles are squeezed with appropriate force to fully expose them to the surface of the skin, giving a feeling that the skin is about to be squeezed out. After it is fixed, the knife can be cut vertically, about 1 cm in depth, and the testicles are squeezed out of the incision to tear or cut off the connected frenulum. Especially for some special breeds, castration time is late, and the boars are larger in size. The frenulum must be cut. The frenulum is connected to the blood vessels, and cutting it will cause bleeding, so sometimes there is a risk of bleeding, death and infection after castration.

[0003] In the prior art, there is a method of electrocoagulation hemostasis, which quickly closes blood vessels by means of heat burning. The electrocoagulation hemostatic pen technology is very mature and is often used in hospitals, beauty salons, etc. The electrocoagulation hemostatic pen mentioned here is not the high-frequency electric knife used in hospital surgery, but an electrocoagulation hemostatic pen with only hemostatic function. The structure and principle of the electrocoagulation hemostatic pen are very simple (heating the electric heating wire of the pen tip to a predetermined temperature), but the electrocoagulation hemostatic pen cannot be used for cutting. This is firstly because the use scenario of the electrocoagulation pen itself does not need to consider cutting, and then in order to improve the heating efficiency, the heating efficiency of the electrocoagulation pen, the heating wire of the electrocoagulation pen tip is a thin copper wire, which is naturally difficult to cut. However, even if the heating wire of the electric heating pen is set to a blade form, it is still difficult to use it in the scene of piglet castration. Piglet castration is a task that requires a lot of efficiency. Employees need to castrate piglets before they grow up. The best castration period is about two or three weeks. Employees need to castrate nearly a thousand pigs during this period. For skilled employees, it will not take more than four minutes from catching the piglet knife to castration to the final spraying. Therefore, the whole castration process is very fast. Therefore, after the electrocoagulation pen in the form of a blade is used to stop bleeding, the temperature of the blade cannot drop quickly, and the blade is still in a high temperature state when cutting next time. Using a high-temperature blade for cutting will burn the wound, leaving the wound in an open state, causing the wound to be unable to heal and extremely prone to infection. Summary of the invention

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] Embodiment 1:

[0055] Reference Figure 1 - Fig.11 .

[0056] An electrothermal hemostatic boar castration knife, comprising:

[0057] The handle 1 has a guide cavity 11 disposed therein;

[0058] The loading frame 2 is slidably connected to the guide cavity 11;

[0059] A cutting head 3 connected to the end of the loading frame 2;

[0060] The heating unit 6 includes a heating resistor 63 disposed on the side wall of the cutting head 3; a power supply module 62 for supplying power to the heating resistor 63; a heating switch 64, which conducts between the power supply module 62 and the heating resistor 63 when the heating switch 64 is closed; and a control module 65 for controlling the heating temperature of the heating resistor 63;

[0061] A cooling chamber 40, in which cooling liquid is stored, is disposed at the end of the guide cavity 11, and the cooling chamber 40 is an annular structure;

[0062] The cutting head 3 has a working state position 10 protruding from the handle 1, and a cooling state position 101 located in the annular structure;

[0063] The wall surface of the cooling chamber 40 facing the cutting head 3 has a liquid outlet 401;

[0064] A liquid storage sponge 41 is disposed inside the cooling chamber 40 , and the liquid storage sponge 41 protrudes from the liquid outlet 401 and contacts the cutting blade 3 .

[0065] During castration, the pig's skin needs to be cut open and the testicles squeezed out through the incision. When making incisions on thousands of pigs, mistakes are inevitable, resulting in the incision being too large and causing excessive bleeding. Also, when castrating larger boars, the frenulum of the testicle cannot be directly torn off and must be cut with a knife. The frenulum has blood vessels and bleeding will occur after cutting.

[0066] Generally, when faced with this kind of bleeding situation, employees usually spray some hemostatic drugs on the pig's wound. Hemostatic drugs cannot guarantee 100% healing of the wound. Depending on the boar's activity, the wound may still rupture, bleed or become infected, which prolongs the wound healing time, affects the growth rate of piglets, and directly affects the time it takes for commercial pigs to be marketed, affecting the pig production efficiency of the pig farm.

[0067] In the prior art, there is a method of electrocoagulation hemostasis, which quickly closes blood vessels by means of heat burning. The electrocoagulation hemostatic pen technology is very mature and is often used in hospitals, beauty salons, etc. The electrocoagulation hemostatic pen mentioned here is not the high-frequency electric knife used in hospital surgery, but an electrocoagulation hemostatic pen that only has the function of hemostasis. For the high-frequency electric knife, it can achieve both cutting and hemostasis, but the high-frequency electric knife requires a large frequency conversion device, and the negative electrode plate needs to be close to the object to be cut. The actual operation is very cumbersome, and the cost is too high to adapt to the use scenario of piglet castration. The structure and principle of the electrocoagulation hemostatic pen are very simple (just heat the heating wire of the pen tip to a predetermined temperature), but the electrocoagulation hemostatic pen cannot be used for cutting. This is firstly because the use scenario of the electrocoagulation pen itself does not need to consider cutting. Then, in order to improve the heating efficiency, the heating wire of the electrocoagulation pen tip is a thin copper wire, which is naturally difficult to cut. However, even if the heating wire of the electrocoagulation pen is set to a blade form, it is still difficult to use it in the scenario of piglet castration. Piglet castration is a task that requires a lot of efficiency. Employees need to castrate piglets before they grow up. The best time for castration is about two or three weeks. Employees need to castrate nearly a thousand pigs during this period. For skilled employees, it will take no more than four minutes from castration with a pig knife to the final spraying of medicine. Therefore, the entire castration process is very fast. Therefore, after the electrocoagulation pen in the form of a blade completes hemostasis, the temperature of the blade cannot drop quickly, and the blade will still be in a high temperature state when cutting next time. Cutting with a high-temperature blade will burn the wound, leaving the wound in an open state, causing the wound to be unable to heal and extremely prone to infection.

[0068] Therefore, piglet castration requires a knife that has the characteristics of cutting, stopping bleeding, cooling and portability.

[0069] In this embodiment, an electrothermal castration hemostatic knife is provided, comprising a handle 1 for holding, and a guide cavity 11 is arranged inside the handle 1 to form a guide stroke 8 extending along the length direction of the handle 1;

[0070] The loading frame 2 is used to install the cutting head 3. When the loading frame 2 slides along the guide stroke 8 to the front end of the guide stroke 8, the cutting head 3 protrudes from the handle 1 so that the cutting head 3 can contact the piglet skin. The position of the cutting head 3 when it protrudes from the handle 1 is the working state position 10; when the loading frame 2 slides to the end of the guide stroke 8, the cutting head 3 enters the guide cavity 11, and the cutting head 3 is in the cooling state position 101.

[0071] The heating unit 6 includes a heating resistor 63, which is arranged on the side wall of the cutting head 3; a power supply module 62, which supplies power to the heating resistor 63; a heating switch 64, which connects the power supply module 62 and the heating resistor 63 when the heating switch 64 is closed; and a control module 65, which controls the heating temperature of the heating resistor 63.

[0072] Specifically, first, the volume of the cutting head 3 should be reduced as much as possible, and it can be set to a blade structure similar to a paper cutter or a razor, so that the heating unit 6 can heat the cutting head 3 to a preset temperature more quickly. In addition, the manufacturing cost of this blade is lower. Since the cutting head 3 will be heated and cooled, its service life is inevitably not as good as that of a traditional lancet. Therefore, using this type of blade cutting head 3, the blade can be replaced in time at a lower cost.

[0073] The side wall of the cutting head 3 is connected to a heating resistor 63, which is specifically configured as a heating wire coiled around the side wall of the cutting head 3. The power supply module 62 can be specifically configured as a battery or a power cord. When the heating switch 64 is closed, current passes through the heating resistor 63, and the heating resistor 63 generates heat.

[0074] The control module 65 is a circuit board. The specific temperature control logic is quite mature in the use of electrocoagulation hemostatic pens and electric soldering irons, so it will not be elaborated here.

[0075] Specifically, the loading frame 2 protrudes from the handle 1 to set a push block for pushing, and the handle 1 has at least one slide groove for the push block to slide. The employee pushes the push block to make the cutting head 3 enter the working state position 10 or the cooling state position 101. The operation process is extremely simple and can be operated with one hand, and will not reduce the efficiency of the employee's castration. And when the cutting head 3 enters the cooling state position 101, it is equivalent to being put into the sheath after being put into the handle 1. When the employee grabs the next piglet, the employee can calmly keep the castration knife by his side without worrying about the cutting blade being contaminated with viruses and bacteria.

[0076] A cooling chamber 40 is provided inside the guide cavity 11, and a cooling liquid is contained in the cooling chamber 40. The cooling chamber 40 is provided at the front end of the guide cavity 11, and the cooling chamber 40 is an annular structure. The loading frame 2 and the cutting head 3 continuously pass through the center of the annular structure when they move. When the cutting head 3 is retracted into the guide cavity 11 and enters the cooling state position 101, the cooling chamber 40 surrounds the cutting head 3 (the cutting head 3 is located at the center of the annular structure), and the wall surface of the cooling chamber 40 facing the cutting head 3 (i.e., the inner wall surface of the annular structure) has a liquid outlet 401.

[0077] Obviously, if only the liquid outlet 401 is opened in the cooling chamber 40, the cooling liquid will continue to drip no matter what position the cutting head 3 is in, and the cutting head 3 in the working state 10 does not need to be cooled, resulting in a large amount of cooling liquid being wasted. The cooling liquid will soon dry up completely, and no cooling liquid can flow to the cutting head 3 in the cooling state 101, and the desire for rapid cooling cannot be achieved.

[0078] In this embodiment, a liquid storage sponge 41 is provided in the cooling chamber 40, and the liquid storage sponge 41 protrudes from the liquid outlet 401 and contacts the cutting blade 3. The sponge can store a large amount of liquid and can disperse the liquid relatively evenly to every corner of the sponge through the capillary effect.

[0079] The cooling liquid is blocked by the liquid storage sponge 41 on the wall of the liquid storage port to prevent meaningless loss of the cooling liquid, and the thickness of the cutting head 3 is lower than the thickness of the loading rack 2, so that when the cutting head 3 is in the working state 10, the side wall of the loading rack 2 can squeeze the liquid storage sponge 41, so that the liquid storage sponge 41 located outside the cooling bin 40 is more compact and the cooling liquid is difficult to flow out. When cooling is needed later, the loading rack 2 leaves the liquid storage sponge 41, and the liquid storage sponge 41 produces an expansion change action, which assists the capillary effect to absorb the cooling liquid into the liquid storage sponge 41 outside the liquid storage bin 42, so that the cooling liquid contacts the cutting head 3.

[0080] The cooling liquid can be water, iodine, alcohol, etc. The use of iodine or alcohol can not only have a cooling effect but also can disinfect the cutting head 3 to avoid virus infection. When using alcohol, the alcohol concentration should be lower than 40% to avoid alcohol burning.

[0081] The electrothermal hemostatic boar castration knife in the present embodiment combines the hemostatic function of the electrocoagulation pen with the cutting function of the common castration knife, and simultaneously, the design of the cooling chamber 40 and the liquid storage sponge 41 enables the heated cutting head 3 to be cooled quickly and prepared for the next cutting, so as to avoid the efficiency of castration caused by long-term waiting. And the cooling chamber 40 is located at the front end of the handle 1, and the employee only needs to simply push the loading rack 2 to switch the position state of the cutting head 3, and the operation is extremely simple and does not require the employee to perform complicated operations, and it is easy to form a habit of use, and then the employee's willingness to use is not reduced, and the employee performs compliant operations so as to finally ensure the castration efficiency while reducing the risk of piglet wound infection. And when the cooling liquid uses disinfectants such as iodine tincture, the cutting head 3 can also be disinfected when cooling, further reducing the risk of wound infection and virus transmission.

[0082] Example 2

[0083] Reference Figure 1 - Figure 4 as well as Figure 6 , Fig. 9 .

[0084] The liquid storage tank 42 stores cooling liquid inside and is connected to the cooling tank 40 through the pipeline 5;

[0085] The volume of the liquid storage tank 42 is larger than that of the cooling tank 40, and at least part of the wall surface is a flexible wall surface 421, and the flexible wall surface 421 is arranged on the outside of the knife handle 1;

[0086] The flexible wall surface 421 forms a first extrusion space, and the first extrusion space is compressed to allow the cooling liquid to flow toward the cooling chamber 40;

[0087] The pipeline 5 has a first non-return structure to prevent the cooling liquid in the cooling tank 40 from flowing to the liquid storage tank 42;

[0088] The liquid storage tank 42 also has a reset air hole in one-way communication with the external air, and the reset air hole allows air to enter when the flexible wall surface 421 rebounds.

[0089] The first non-return structure can be specifically configured as a micro one-way valve.

[0090] The electric hemostatic boar castration knife is a castration knife, so it is necessary to ensure the employee's grip feel. Therefore, the volume of the handle 1 is limited, so the volume of the cooling chamber 40 in the handle 1 is limited, and the internal cooling liquid may not be sufficient to meet the needs of multiple cooling, and the liquid storage sponge 41 absorbs the cooling liquid in the cooling chamber 40 at a slow speed, especially when there is insufficient liquid in the cooling chamber 40. This is very likely to cause the cutting head 3 to come into contact with the dry liquid storage sponge 41 when entering the cooling state position 101, causing burning, and then the cooling chamber 40 needs to be replaced, wasting a lot of time.

[0091] The electrothermal hemostatic boar castration knife in this embodiment is also provided with a liquid storage tank 42 for storing more cooling liquid. The liquid storage tank 42 is connected with the cooling tank 40 through a pipeline 5 to ensure that the liquid in the liquid storage tank 42 can flow to the cooling tank 40.

[0092] The liquid storage tank 42 can be specifically hollowed out on the rear side of the knife handle 1 to form a cavity. Since the liquid storage tank 42 is arranged on the outside of the knife handle 1, the specific position is relatively arbitrary and the volume is not limited. Therefore, the volume can be much larger than the cooling tank 40, forming a larger capacity to store more cooling liquid.

[0093] In addition, at least part of the wall surface of the liquid storage bin 42 is a flexible wall surface 421, forming a first squeezing space (i.e., the internal space of the liquid storage chamber), and the flexible wall surface 421 is arranged outside the knife handle 1 to ensure that the flexible wall surface 421 can be pressed by a hand. When the flexible wall surface 421 is pressed, the first squeezing space contracts, and the cooling liquid inside is squeezed into the cooling bin 40. As the flexible wall surface 421 is continuously pressed, the first squeezing space is continuously reduced, and the employees can immediately know the remaining amount of the cooling liquid, so as to replenish the cooling liquid in time and avoid stopping work to replenish water during the castration process.

[0094] It is understood that the liquid storage bin 42 must have a liquid injection hole for injecting cooling liquid. The cooling bin 40 can be preferably arranged at the rear end of the knife handle 1 to ensure that the employee does not squeeze the flexible wall 421 during the gripping process and press the flexible wall 421 when putting down the knife after the cutting action is completed.

[0095] Example 3

[0096] Reference Figure 1 - Figure 4 as well as Figure 6 , Fig.11 .

[0097] It includes: an extrusion chamber 43, which is connected with the cooling chamber 40 and the liquid storage chamber 42 through the pipeline 5 to form the second extrusion space;

[0098] The extrusion chamber 43 is disposed between the first non-return structure and the cooling chamber 40;

[0099] Wherein, a second non-return structure 51 and a first non-return structure 52 are provided between the extrusion chamber 43 and the cooling chamber 40;

[0100] The loading frame 2 has an extrusion protrusion, and the extrusion protrusion interferes with the extrusion cavity 43 along the guide stroke 8. When the cutting head 3 moves toward the cooling state position 101, the extrusion protrusion compresses the extrusion cavity 43.

[0101] The second check structure 51 is the first check structure; 52 is specifically configured as a one-way valve with the same direction as the first check structure.

[0102] In Example 2, the design of the flexible wall 421 can solve the problem of slow water delivery of the liquid storage sponge 41, but employees need to press it individually each time, and the amplitude of the pressing determines the speed of the infusion, which can easily cause excessive delivery, resulting in overflow and waste of cooling liquid.

[0103] In this regard, in the present embodiment, an extrusion chamber 43 is added, which is connected with the liquid storage tank 42 and the cooling tank 40 through the pipeline 5. The extrusion chamber 43 forms a second extrusion space, and the extrusion chamber 43 is arranged between the first check structure and the cooling tank 40. That is to say, when the second extrusion space is compressed, the first check structure is closed, and the cooling liquid will be blocked by the first check structure, and the second check structure 51 (the first check structure; 52) is opened, and the cooling liquid flows unidirectionally toward the cooling tank 40; then, after the pressure on the extrusion chamber 43 is withdrawn, the extrusion chamber 43 rebounds, and the second extrusion space expands. The second check structure 51 (the first check structure; 52) is closed to prevent the cooling liquid in the cooling tank 40 from flowing back, and the first check structure is opened. The negative pressure generated by the expansion of the second extrusion space sucks the cooling liquid in the liquid storage tank 42 into the second extrusion space, so that enough cooling liquid is still retained in the second extrusion space.

[0104] The loading frame 2 is provided with an extrusion protrusion, and the extrusion protrusion interferes with the extrusion cavity 43 along the guide stroke 8. When the cutting head 3 moves toward the cooling state position 101, the extrusion protrusion compresses the extrusion cavity 43. That is to say, when the extrusion protrusion follows the loading frame 2 to slide along the guide stroke 8, the extrusion protrusion will abut against the extrusion cavity 43. Since the extrusion cavity 43 is made of elastic material, the extrusion cavity 43 will be deformed, resulting in an increase in the pressure in the second extrusion space, until it moves to the end of the guide stroke 8, that is, the cutting head 3 moves to the cooling state position 101. Here, the movement process of the loading frame 2 is named as retreat. In the process of continuous retreat, the extrusion cavity 43 is continuously squeezed, so that the cooling liquid in the second extrusion space is continuously replenished into the cooling bin 40, and the pressure of the liquid storage port is also increased, so that the cooling liquid can soak the liquid storage sponge 41 faster.

[0105] In this embodiment, the extrusion cavity 43 cooperates with the extrusion protrusion provided on the loading frame 2, so that the staff only needs to retract the cutting head 3 to replenish the cooling liquid toward the liquid storage sponge 41 and the cooling chamber 40. No additional operation is required, and the cooling liquid will not be forgotten after cooling, which completely avoids the contact between the cutting head 3 and the dry liquid storage sponge 41 (combined with the liquid storage chamber 42 made of flexible material).

[0106] Specifically, the extrusion chamber 43 is a columnar structure, one end of which is fixedly connected to the knife handle 1, and the other end of which faces the extrusion protrusion;

[0107] Wherein, the circumferential side wall of the extrusion cavity 43 has an elastic folding structure 431 along the direction of the guide stroke 8;

[0108] The elastic folding structure 431 of the longitudinal section of the extrusion cavity 43 is wavy.

[0109] The extrusion cavity 43 is a columnar structure, which can be a cylinder or a prism, one end of which is fixedly connected to the knife handle 1. When the extrusion protrusion extrudes the extrusion cavity 43, this end serves as a fixed end, so that the extrusion cavity 43 does not slide with the extrusion protrusion; the other end faces the extrusion protrusion and is used to abut the extrusion protrusion facing the cooling state position 101;

[0110] The axial side wall of the extrusion cavity 43 has an elastic folding structure 431 similar to an accordion, a bellows or the like, so that the extrusion cavity can shrink and rebound along the direction of the guide stroke 8 .

[0111] The elastic folding structure 431 of the extrusion cavity 43 is in a wave shape in the longitudinal section.

[0112] Example 4

[0113] Reference Figure 1 - Figure 6 .

[0114] The power supply module 62 is provided with a conducting electrode A61, and the conducting electrode A61 is fixedly disposed in the guide cavity 11;

[0115] The cutting head 3 is provided with a conducting electrode B31, and the conducting electrode B31 interferes with the conducting electrode A61 along the guide stroke 8. When the cutting head 3 moves toward the working state position 10, the conducting electrode A61 abuts against the conducting electrode B31.

[0116] It is understandable that after the hemostasis is completed, the cutting head 3 needs to be cooled down. Before that, the heating must be stopped first before the cooling can be performed. Otherwise, the continuously heated cutting head 3 will quickly evaporate the cooling liquid in the liquid storage sponge 41, causing the dry cooling sponge to contact the high-temperature cutting head 3, which may eventually cause burning. Therefore, after each use, the heating switch 64 must be pressed to turn off the power, and then the cutting head 3 is put into the cooling state position 101. These two operation steps cannot be reversed, and the first step cannot be omitted, but manual operation is inevitable.

[0117] In this application, an insurance design is made for this risk. The power supply module 62 is provided with a conductive electrode A61, and the cutting head 3 is provided with a conductive electrode B31. When the conductive electrode A61 contacts the conductive electrode B31, the power supply module 62 heats the cutting head 3.

[0118] The conductive electrode B31 and the conductive electrode A61 interfere with each other along the guide stroke 8, and when the cutting head 3 moves toward the working state position 10, the conductive electrode A61 abuts against the conductive electrode B31. That is, when the cutting head 3 is in the working state position 10, the conductive electrode B31 abuts against the conductive electrode A61 to form conduction, and then as the cutting head 3 moves toward the cooling state position 101, the conductive electrode B31 gradually separates from the conductive electrode A61, thereby powering off and stopping the heating of the cutting head 3.

[0119] In the embodiment, the power-off operation is integrated into the push-pull loading frame 2. When the cutting head 3 leaves the working state position 10, the path between the cutting head 3 and the power supply unit 6 is necessarily disconnected, and there is no risk of ignition even if the employee forgets to turn off the power switch.

[0120] Example 5

[0121] Reference Figure 7 and Figure 8 .

[0122] The handle 1 is provided with a limiting slide groove 12, and the limiting slide groove 12 is connected to the guide cavity 11;

[0123] The loading frame 2 has a sliding push block 21 and a pressing protrusion 22, and the sliding push block 21 and the pressing protrusion 22 pass through the limiting sliding groove 12 and protrude from the tool handle 1;

[0124] The limiting slide groove 12 is provided with a limiting buckle A121 at one end close to the cutting head 3, and the sliding push block 21; the extrusion protrusion; 22 is provided with a limiting buckle B221;

[0125] Wherein, the sliding push block 21 and the extrusion protrusion 22 have an elastic deformation stroke 9 approaching the guide cavity 11 so as to release the engagement between the limit buckle A121 and the limit buckle B221.

[0126] It is understandable that when the cutting head 3 is in the working state 10, the cutting head 3 will be subjected to a thrust to slide along the guide stroke 8 during cutting. If the cutting head 3 is not in a stable state, it is obviously impossible to cut. For this purpose, the handle 1 is provided with a limit slide 12 in this embodiment, and the loading frame 2 is provided with a sliding push block 21 and a pressing protrusion 22 passing through the limit slide 12, and the sliding push block 21 and the pressing protrusion 22 abut against the end of the limit slide 12 to form a limit. In addition, a limiting buckle A121 is provided at one end of the limiting slide groove 12 close to the cutting head 3, and a sliding push block 21 and an extrusion protrusion 22 are provided with a limiting buckle B221. When the cutting head 3 is in the working state 10, the limiting buckle A121 and the limiting buckle B221 are engaged with each other to prevent the cutting head 3 from retreating into the handle 1, and the sliding push block 21 and the extrusion protrusion 22 have an elastic deformation stroke 9 approaching the guide cavity 11 to release the engagement between the limiting buckle A121 and the limiting buckle B221.

[0127] The elastic deformation can be formed by pressing the sliding push block 21; squeezing the protrusion 22 to deform the loading frame 2 as a whole so that the limit buckle A121 and the limit buckle B221 are misaligned and the clamping is released, or a groove is provided on the wall of the sliding push block 21; squeezing the protrusion 22 so that the sliding push block 21; squeezing the protrusion 22 can be elastically deformed around the corner of the groove, and the limit buckle B221 is driven away from the limit buckle A121 during the deformation process. It is similar to the buckle structure of the battery back cover of the remote control.

[0128] Example 6

[0129] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Fig.10 .

[0130] The loading frame 2 includes a loading frame 2A and a loading frame 2B, both of which are connected to the cutting head 3;

[0131] It also includes a reversing assembly 7 connected to the loading rack 2A and the loading rack 2B so that the two loading racks 2A and the loading rack 2B move in opposite directions.

[0132] When cooling the cutting blade 3, the employee needs to castrate the second pig after catching it. This interval is about three minutes. It is not enough to reduce the temperature of the cutting blade 3 to below 50°C during this period of time. If you want to cool it down further, you need to continue waiting.

[0133] In this regard, in this embodiment, two loading racks 2 are set in the handle 1, and the loading rack 2A and the loading rack 2B are both equipped with a cutting head 3. When the loading rack 2A drives the cutting head 3 to be in the working state 10, the cutting head 3 of the loading rack 2B is in the cooling state 101 for cooling. The two cutting heads 3 are circulated and used, which extends the cooling time by two times, and increases the contact time between the cooling liquid and the cutting head 3 so that the temperature of the cutting head 3 can be reduced to a lower level.

[0134] The two loading racks 2 and the two cutting heads 3 can indeed effectively extend the cooling time, but this will bring inconvenience to the operation. The loading rack 2A needs to be pushed to the front end of the guide stroke 8, and the loading rack 2B needs to be pushed to the rear end of the guide stroke 8. In the aforementioned embodiments, we have continuously simplified the operating steps of the tool use. Now, using two cutting heads 3 will increase the operating steps, which is not conducive to the user experience, which is obviously undesirable.

[0135] In this regard, the present embodiment further includes a reversing assembly 7 to enable the loading rack 2A and the loading rack 2B to be linked in opposite directions.

[0136] Specifically, the reversing assembly 7 includes: a fixed pulley 71 and a connecting rope 72;

[0137] The rotating shaft of the fixed pulley 71 is fixedly arranged at the end of the handle 1;

[0138] Both ends of the connecting rope 72 are connected to the loading frame 2A and the loading frame 2B respectively. The fixed pulley 71 is fixedly arranged at the rear end of the handle 1. The middle section of the connecting rope 72 bypasses the fixed pulley 71 to form a reversing structure of the fixed pulley 71.

[0139] The fixed pulley 71 reversing structure is a classic reversing structure, and the length of the connecting rope 72 is fixed. When the loading frame 2A is away from the fixed pulley 71, the loading frame 2B is close to the fixed pulley 71, that is, when the loading frame 2A drives the cutting head 3 to approach the working state position 10, the loading frame 2B drives the cutting head 3 to approach the cooling state position 101, and vice versa. The principle is the same.

[0140] Only by driving the loading frame 2A or the loading frame 2B, the loading frame 2A and the loading frame B can simultaneously move in the opposite direction.

[0141] Or, specifically, the reversing assembly 7 includes two transmission racks 73 respectively arranged on the wall surfaces opposite to the loading frame 2A and the loading frame 2B;

[0142] And a reversing gear 74 is arranged between the two transmission racks 73 , and the rotating shaft of the reversing gear 74 is fixedly arranged on the tool handle 1 .

[0143] The reversing assembly 7 is configured as a gear rack transmission. When the loading frame 2A drives the transmission rack 73 to move, the reversing gear 74 rotates. The other transmission rack 73 is located on the opposite side of the transmission rack 73A. The rotation of the reversing gear 74 provides an opposite force to the rotating rack on the opposite side of the loading frame 2, so that the loading frame 2A and the loading frame 2B move in opposite directions. The loading frame 2A and the loading frame B can simultaneously move in opposite directions by only driving the loading frame 2A or the loading frame 2B.
