Description

Technical Field

[0001] The present invention relates to the technical field of animal husbandry and veterinary tools, and specifically to an adjustable oral retractor structure for animal husbandry and veterinary medicine. Background Art

[0002] As is well known, in the field of animal husbandry and veterinary medicine, oral retractor devices are very important tools, mainly used for examining and treating diseases and problems related to the oral cavity of animals. The rod-type mouth gag utilizes the lever principle to retract the oral cavity of animals. Generally, it has a relatively long handle and a retracting part. Taking the bovine lever-type mouth gag as an example, the veterinarian puts the retracting part into the cow's oral cavity, and by pressing the handle, a relatively large force is generated by the retracting part to retract the oral cavity. The advantage of this kind of mouth gag is that it can generate a relatively large retracting force and is suitable for large livestock. However, the operation requires certain skills, and if used improperly, it may cause damage to the animal's oral cavity.

[0003] When animal husbandry and veterinary medicine professionals conduct internal oral examinations or treatments on large livestock animals, the problems existing in the prior art are as follows: Since the body size of large livestock animals can increase several times from infancy to adulthood, and the heights or internal oral structures of different animals are different, the lever-type mouth gags in the prior art are difficult to detect different animals. Moreover, even when the animal's oral cavity is retracted, it is still difficult for personnel to operate when the animal's head moves. The recommended mouth gag or the lockable mouth gag is difficult to be used on large animals, and it is relatively inconvenient to use.

[0004] Based on the above-mentioned situations, we found that it is very difficult for the adjustable oral retractor structure for animal husbandry and veterinary medicine in the prior art to avoid the above problems at the same time. Therefore, we propose an adjustable oral retractor structure for animal husbandry and veterinary medicine that can be applicable to different body sizes or various oral structures, and has the advantages of providing support for long-time opening and avoiding large movements of the animal's head. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an adjustable oral retractor structure for animal husbandry and veterinary medicine, which has the advantages of being applicable to different body sizes or various oral structures, providing support for long-time opening, and avoiding large movements of the animal's head.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: an adjustable oral opening structure for animal husbandry and veterinary medicine, comprising a pedal, a head frame is fixedly connected to the right side of the top of the pedal, an adjustment frame is fixedly connected to the top of the head frame, an opening component is provided on the front side of the adjustment frame, a suspension is provided on the top of the pedal, an end frame is fixedly connected to the top of the suspension, an electric cylinder is fixedly connected to the outer side of the end frame, the telescopic end of the electric cylinder passes through the end frame and is fixedly connected to a sliding sleeve, the bottom of the sliding sleeve is fixedly connected to a connecting frame, and the bottom of the connecting frame is fixedly connected to a head and neck frame;

[0007] The opening assembly comprises a vertical frame, the inner side of the vertical frame is slidably connected with a transmission block, the left side of the vertical frame and the front side of the transmission block are both movably connected with opening pliers, a safety cylinder is provided between the bottom opening pliers and the top opening pliers, the inner side of the top opening pliers is rotatably connected with a short shaft, and the outer side of the short shaft is rotatably connected with the bottom opening pliers;

[0008] The opening pliers include a handle, a clamp frame is fixedly connected to the left side of the handle, a connecting pin is rotatably connected to the inner side of the clamp frame, an opening and closing claw is rotatably connected to the outer side of the connecting pin, the top and bottom of the opening and closing claw are fixedly connected to torsion springs, and the torsion spring is fixedly connected to the clamp frame on the side away from the closing claw.

[0009] By adopting the above technical scheme, a pedal is set as the installation and placement position of the structure, and it can also be used as a positioning position for livestock animals to step on or a position for the front hooves of larger livestock animals to be placed. The set adjustment frame is used to support the opening component, and the horizontal or vertical position of the opening component can be flexibly changed. The opening component serves as the main opening part. When in use, the opening and closing claws of the opening pliers can be placed inside the mouth of the livestock animal, and then the transmission block is moved along the vertical frame. When the transmission block moves, it will drive the handle of the opening pliers in contact with it to rise vertically. At this time, the position of the opening pliers on the other side is inconvenient, so the opening and closing claws of the bottom opening pliers will rotate along the short axis. When the angle between the bottom opening and closing claws and the top opening and closing claws increases, the lower part of the animal's mouth will be stretched to open the mouth to achieve the opening. The effect is that the degree of opening can be adjusted by adjusting the position of the transmission block on the inner side of the vertical frame as needed, and when the opening pliers are inserted into the mouth of an animal with a smaller mouth, the parts of the opening and closing claws that contact the two sides of the animal's mouth are arc surfaces, and when inserted into the mouth, the two opening and closing claws on the same horizontal plane will be pressed along the arc surfaces, and rotate along the connecting pin and approach each other. At this time, the torsion spring accumulates force until the torsion spring rebounds when the claws are inserted into the mouth to push the opening and closing claws to open each other and fit the inside of the mouth. Before the mouth is opened, the telescopic end of the electric cylinder can be extended along the end frame, and the sliding sleeve connected thereto will approach each other along the suspension, and the two sets of sliding sleeves and the connecting frame and head and neck frame connected at the bottom will approach the animal's head and contact the neck or both sides of the head to assist in fixing the head position, thereby reducing the range of movement of the animal's head.

[0010] The present invention is further configured such that: the insurance cylinder includes an outer cylinder, an outer partition cylinder is fixedly connected to the inner side of the outer cylinder, an extension cylinder is slidably connected to the inner side of the outer partition cylinder, an inner partition cylinder is fixedly connected to the inner side of the extension cylinder, a metal cylinder is slidably connected to the inner side of the inner partition cylinder, a metal rod is slidably connected to the inner side of the metal cylinder, and the inner side of the outer cylinder is filled with hydraulic fluid.

[0011] With the above technical solution, by arranging the outer cylinder in cooperation with the outer partition cylinder, when the top opening claws and the bottom opening claws move away from each other when the animal's mouth is opened, the metal rod connected to the top opening claws will be pulled out from the metal cylinder. Similarly, as the opening size extends, the metal cylinder will be pulled out from the inner partition cylinder, and the extension cylinder will be pulled out from the inner side of the outer partition cylinder to fit the opening size. When the biting force of the animal is too large or the structure fails and is damaged, resulting in a sudden loss of the supporting force between the top opening claws and the bottom opening claws, the metal cylinder will press against the hydraulic fluid inside the inner partition cylinder and push the hydraulic fluid to flow. The extension cylinder will push the hydraulic fluid inside the outer partition cylinder. When the hydraulic fluid flows, it will have a hydraulic buffering effect to slow down the approaching speed between the top opening claws and the bottom opening claws, enabling the operator to withdraw their hand in time or take out the detection and treatment instruments from the oral cavity, and avoiding serious injuries to the operator's hand or the animal's oral cavity.

[0012] The present invention is further configured such that: bottom blocks are fixedly connected to the bottom of the inner side of the outer cylinder and the bottom of the inner side of the extension cylinder, and flow holes are formed at the top and bottom of the inner sides of the outer partition cylinder and the inner partition cylinder.

[0013] With the above technical solution, by arranging the fluid holes, it provides space for the flow of the hydraulic fluid. The bottom blocks can facilitate the limitation of the extreme movement positions inside the extension cylinder and the metal cylinder, avoiding the abnormal flow or difficulty in resetting of the fluid caused by blocking the flow holes.

[0014] The present invention is further configured such that: movable grooves are formed at the bottom of the top opening claws and the top of the bottom opening claws. A thin rod is fixedly connected to the inner side of the top movable groove. A rotating cylinder is rotatably connected to the outer side of the thin rod, and the rotating cylinder is fixedly connected to the top of the metal rod.

[0015] With the above technical solution, by arranging the movable grooves, it can facilitate the installation position of the insurance cylinder. The arranged thin rod can facilitate the stable connection between the rotating cylinder and the metal rod and provide space for the structural movement.

[0016] The present invention is further configured such that: a rotating shaft bracket is fixedly connected to the top of the bottom opening claws. The rotating shaft bracket is arranged outside the bottom movable groove, and the side of the rotating shaft bracket close to the outer cylinder is rotatably connected to the outer cylinder. Friction protrusions are fixedly connected to the top of the top opening claws and the bottom of the bottom opening claws.

[0017] With the above technical solution, by setting the rotating shaft frame, it is convenient to stably install the outer cylinder and provide a space for the structure to move. When the top opening and closing claws and the bottom opening and closing claws are opened, due to a certain angular deflection, the outer cylinder and the metal rod will tilt along the rotating shaft frame and the rotating cylinder, avoiding abnormal use caused by the structure being stuck.

[0018] The present invention is further configured as: an adjusting screw is rotatably connected to the inner side of the vertical frame, the outer side of the adjusting screw is threadedly connected to the transmission block, a short pin is fixedly connected to the front side of the transmission block, the outer side of the short pin is rotatably connected to an assembly sleeve, the outer side of the assembly sleeve is slidably connected to the inner side of the front grip, and a rotating rod is movably connected to the inner side of the top of the adjusting screw.

[0019] With the above technical solution, by setting the adjusting screw, when opening and closing the two groups of opening pliers, the adjusting screw can be rotated through the rotating rod. At this time, the connected transmission block will move vertically along the inner side of the vertical frame, and the short pin will be partially pulled out from the inner side of the front grip along the assembly sleeve to achieve the effect of rotating the front opening pliers along the short axis.

[0020] The present invention is further configured as: a card sleeve is clamped on the outer side of the rear grip, a fastening screw is threadedly connected to the top of the card sleeve, the bottom of the fastening screw contacts the rear grip, and the rear side of the card sleeve is movably connected to the outer side of the adjustment frame.

[0021] With the above technical solution, by setting the card sleeve, it is convenient to install the adjustment frame and the opening assembly. Similarly, the opening assembly can be removed from the adjustment frame by rotating the fastening screw to make it relatively loose from the rear grip for easy carrying or separate use.

[0022] The present invention is further configured as: the adjustment frame includes a longitudinal sliding frame, a transverse sliding frame is slidably connected to the outer side of the longitudinal sliding frame, a vertical sliding frame is slidably connected to the outer side of the transverse sliding frame, and the outer side of the vertical sliding frame is slidably connected to the card sleeve.

[0023] With the above technical solution, by setting the longitudinal sliding frame, it is convenient to adjust the left - right movement of the opening assembly. The transverse sliding frame is used to limit and support the front - rear movement of the opening assembly, and the vertical sliding frame can facilitate the adjustment of the vertical position of the opening assembly to adjust the structural position according to the head height of different animals.

[0024] The present invention is further configured as: a driving frame is fixedly connected to the front side of the pedal, a lead screw is rotatably connected to the inner side of the driving frame, the right side of the lead screw is externally connected to a control motor, a driving block is threadedly connected to the outer side of the lead screw, and the top of the driving block is fixedly connected to the suspension.

[0025] With the above technical solution, by providing an active frame in cooperation with a lead screw, it is convenient to drive the lead screw to rotate through an externally controlled motor, thereby driving the active block to move horizontally along the active frame so as to adjust the position of the suspension according to the position of the animal.

[0026] The present invention is further configured as follows: on the front side and the rear side of the top of the pedal, side rails are fixedly connected, on the rear side of the pedal, a driven frame is fixedly connected, inside the driven frame, a driven block is slidably connected, and the top of the driven block is fixedly connected to the suspension.

[0027] With the above technical solution, by providing side rails, they are used to block the sides of the animal's body to limit the range of movement of the animal. The arranged driven block slides inside the driven frame, which can facilitate the limiting and auxiliary support of the movement of the suspension.

[0028] Compared with the prior art, the present invention provides an adjustable oral dilator structure for livestock veterinarians, having the following beneficial effects:

[0029] For this adjustable oral dilator structure for livestock veterinarians, by providing a pedal as the installation and placement position of the structure, and at the same time, it can also be used as a positioning point for livestock animals to step on or for the front hooves of larger livestock animals to be placed. The provided adjustment frame is used as the support of the opening component, and at the same time, the horizontal or vertical position of the opening component can be flexibly changed. The opening component is the main opening part. When in use, the opening and closing claws of the opening pliers can be placed inside the oral cavity of the livestock animal, and then the transmission block is moved along the vertical frame. When the transmission block moves, it will drive the grip position of the opening pliers in contact with it to rise vertically. At this time, the position of the other side opening pliers remains unchanged. Therefore, the opening and closing claws of the bottom opening pliers will rotate along the short axis. When the angle between the bottom opening and closing claws and the top opening and closing claws increases, the lower part of the animal's oral cavity will be opened to achieve the effect of opening. According to the need, adjusting the position of the transmission block inside the vertical frame can adjust the degree of opening. When the opening pliers are inserted into the oral cavity of an animal with a smaller mouth, the parts of the opening and closing claws in contact with both sides of the animal's mouth are arc surfaces. When inserted into the mouth, it will press against the two opening and closing claws on the same horizontal plane along the arc surface to rotate and approach each other along the connecting pin. At this time, the torsion spring stores energy. Until it is inserted into the oral cavity, the torsion spring rebounds to push the opening and closing claws to open and fit the inside of the oral cavity. Before the oral cavity is dilated, the telescopic end of the electric cylinder can be driven to extend along the end frame, and the sliding sleeves connected thereto will approach each other along the suspension. The two sliding sleeves and the connecting frame and the head and neck frame connected to the bottom will approach the animal's head and contact the two sides of the neck or head to assist in fixing the head position and reducing the range of movement of the animal's head.

Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Example 1, please refer to Figure 1-8, an adjustable oral opening structure for animal husbandry and veterinary medicine, comprising a pedal 1, a head frame 2 is fixedly connected to the right side of the top of the pedal 1, an adjustment frame 3 is fixedly connected to the top of the head frame 2, an opening component 4 is arranged on the front side of the adjustment frame 3, a suspension frame 5 is arranged on the top of the pedal 1, an end frame 6 is fixedly connected to the top of the suspension 5, an electric cylinder 7 is fixedly connected to the outer side of the end frame 6, a telescopic end of the electric cylinder 7 passes through the end frame 6 and is fixedly connected to a sliding sleeve 8, a connecting frame 9 is fixedly connected to the bottom of the sliding sleeve 8, and a head and neck frame 10 is fixedly connected to the bottom of the connecting frame 9;

[0041] The opening assembly 4 comprises a vertical frame 401, the inner side of the vertical frame 401 is slidably connected with a transmission block 402, the left side of the vertical frame 401 and the front side of the transmission block 402 are both movably connected with an opening clamp 403, a safety cylinder 404 is provided between the bottom opening clamp 403 and the top opening clamp 403, the inner side of the top opening clamp 403 is rotatably connected with a short shaft 405, and the outer side of the short shaft 405 is rotatably connected with the bottom opening clamp 403;

[0042] The opening pliers 403 include a handle 403a, a clamp frame 403b is fixedly connected to the left side of the handle 403a, a connecting pin 403c is rotatably connected to the inner side of the clamp frame 403b, an opening and closing claw 403d is rotatably connected to the outer side of the connecting pin 403c, a torsion spring 403e is fixedly connected to the top and bottom of the opening and closing claw 403d, and a side of the torsion spring 403e away from the closing claw 403d is fixedly connected to the clamp frame 403b;

[0043] By setting the adjustment frame 3 to serve as a support for the opening component 4, the horizontal or vertical position of the opening component 4 can be flexibly changed. The opening component 4 serves as the main opening part. When in use, the opening and closing claw 403d of the opening pliers 403 can be placed inside the oral cavity of the livestock, and then the transmission block 402 is moved along the vertical frame 401. The transmission block 402 will drive the handle 403a of the opening pliers 403 in contact with it to rise vertically while moving. At this time, the position of the opening pliers 403 on the other side is inconvenient, so the opening and closing claw 403d of the bottom opening pliers 403 will rotate along the short axis 405, and the bottom opening and closing claw 403d and the top opening and closing claw 403d will rotate. When the angle between 03d increases, the lower part of the animal's mouth will be stretched open to achieve the effect of opening. The degree of stretching can be adjusted by adjusting the position of the transmission block 402 on the inner side of the vertical frame 401 as needed. When the opening pliers 403 are inserted into the mouth of an animal with a smaller mouth, the parts of the opening and closing claws 403d that contact the two sides of the animal's mouth are arc surfaces. When inserted into the mouth, the two opening and closing claws 403d on the same horizontal plane will be pressed along the arc surfaces, and will rotate along the connecting pin 403c and approach each other. At this time, the torsion spring 403e accumulates force until it is inserted into the mouth. The torsion spring 403e rebounds to push the opening and closing claws 403d to open each other and fit the inside of the mouth.

[0044] Among them, the safety cylinder 404 includes an outer cylinder 404a. An outer partition cylinder 404b is fixedly connected to the inner side of the outer cylinder 404a. An extension cylinder 404c is slidably connected to the inner side of the outer partition cylinder 404b. An inner partition cylinder 404d is fixedly connected to the inner side of the extension cylinder 404c. A metal cylinder 404e is slidably connected to the inner side of the inner partition cylinder 404d. A metal rod 404f is slidably connected to the inner side of the metal cylinder 404e. The inner side of the outer cylinder 404a is filled with oil. By arranging the outer cylinder 404a in cooperation with the outer partition cylinder 404b, when the top and bottom opening and closing claws 403d are opened at the animal's mouth, the top and bottom opening and closing claws 403d move away from each other, and the metal rod 404f connected to the top opening and closing claw 403d will be pulled out from the metal cylinder 404e. Similarly, as the opening size extends, the metal cylinder 404e will be pulled out from the inner partition cylinder 404d, and the extension cylinder 404c will be pulled out from the inner side of the outer partition cylinder 404b to fit the opening size. When the biting force of the animal is too large or the structure fails and is damaged, resulting in a sudden loss of the supporting force between the top and bottom opening and closing claws 403d, the metal cylinder 404e will press against the oil inside the inner partition cylinder 404d and push the oil to flow. The extension cylinder 404c will push the oil inside the outer partition cylinder 404b. When the oil flows, it will have a hydraulic buffering effect to slow down the approaching speed between the top and bottom opening and closing claws 403d, enabling the operator's hand to be withdrawn in time or the detection and treatment instruments to be taken out of the oral cavity, avoiding serious injuries to the operator's hand or the animal's oral cavity. Bottom blocks 11 are fixedly connected to the bottom of the inner side of the outer cylinder 404a and the bottom of the inner side of the extension cylinder 404c. Flow holes 12 are provided at the top and bottom of the inner sides of the outer partition cylinder 404b and the inner partition cylinder 404d. By arranging the fluid holes, space is provided for the flow of the oil. The bottom blocks 11 can facilitate the limitation of the extreme movement positions inside the extension cylinder 404c and the metal cylinder 404e, avoiding the abnormal flow or difficulty in resetting of the fluid caused by the blockage of the flow holes 12. Activity grooves 13 are provided at the bottom of the top opening and closing claw 403d and the top of the bottom opening and closing claw 403d. A thin rod 14 is fixedly connected to the inner side of the top activity groove 13. A rotating cylinder 15 is rotatably connected to the outer side of the thin rod 14. The rotating cylinder 15 is fixedly connected to the top of the metal rod 404f. By arranging the activity grooves 13, it can facilitate the installation position of the safety cylinder 404. The provided thin rod 14 can facilitate the stable connection between the rotating cylinder 15 and the metal rod 404f and provide space for the structural activity. A rotating shaft frame 16 is fixedly connected to the top of the bottom opening and closing claw 403d. The rotating shaft frame 16 is arranged outside the bottom activity groove 13. One side of the rotating shaft frame 16 close to the outer cylinder 404a is rotatably connected to the outer cylinder 404a. Friction protrusions are fixedly connected to the top of the top opening and closing claw 403d and the bottom of the bottom opening and closing claw 403d. By arranging the rotating shaft frame 16, it can facilitate the stable installation of the outer cylinder 404a and provide space for the structural activity.When the top opening and closing claw 403d and the bottom opening and closing claw 403d are opened, due to a certain angular deflection, the outer cylinder 404a and the metal rod 404f will tilt along the rotating shaft frame 16 and the rotating cylinder 15, avoiding abnormal use caused by the structure being stuck. The inner side of the vertical frame 401 is rotatably connected with an adjusting screw 17. The outer side of the adjusting screw 17 is threadedly connected with a transmission block 402. The front side of the transmission block 402 is fixedly connected with a short pin 18. The outer side of the short pin 18 is rotatably connected with an assembly sleeve 19. The outer side of the assembly sleeve 19 is slidably connected with the inner side of the front grip 403a. The inner side of the top of the adjusting screw 17 is movably connected with a rotating rod. By setting the adjusting screw 17, when opening and closing the two groups of opening pliers 403, the adjusting screw 17 can be rotated through the rotating rod. At this time, the connected transmission block 402 will move vertically along the inner side of the vertical frame 401, and the short pin 18 will be partially pulled out from the inner side of the front grip 403a along the assembly sleeve 19 to achieve the effect of rotating the front opening pliers 403 along the short shaft 405. A clamping sleeve 20 is clamped on the outer side of the rear grip 403a. The top of the clamping sleeve 20 is threadedly connected with a fastening screw. The bottom of the fastening screw contacts the rear grip 403a. The rear side of the clamping sleeve 20 is movably connected with the outer side of the adjustment frame 3. By setting the clamping sleeve 20, it is convenient to install the adjustment frame 3 and the opening assembly 4. Similarly, the opening assembly 4 can also be removed from the adjustment frame 3 by rotating the fastening screw to make it relatively loose from the rear grip 403a for easy carrying or separate use.,

[0045] The working principle of this embodiment is as follows: by setting up the adjustment frame 3 to serve as the support of the opening component 4, the horizontal or vertical position of the opening component 4 can be flexibly changed. The opening component 4 serves as the main opening part. When in use, the opening and closing claws 403d of the opening pliers 403 can be placed inside the oral cavity of the livestock. Because the parts of the opening and closing claws 403d that contact the two sides of the animal's mouth are arc surfaces, when inserted into the mouth, the two opening and closing claws 403d on the same horizontal plane will be pressed along the arc surface and rotate along the connecting pin 403c and approach each other. At this time, the torsion spring 403e accumulates force until it is inserted into the oral cavity. The torsion spring 403e rebounds to push the opening and closing claws 403d to open each other and fit the inside of the oral cavity. After that, the adjusting screw 17 can be rotated to move the transmission block 402 on the inner side of the vertical frame 401. When the transmission block 402 moves, it will drive the handle 403a of the opening pliers 403 in contact with it to rise vertically. At this time, the position of the opening pliers 403 on the other side is inconvenient, so the opening and closing claws 403d of the bottom opening pliers 403 are The metal cylinder 404e is pulled out of the inner spacer 404d and the extension cylinder 404c is pulled out of the outer spacer 404b. The inner side is pulled out to fit the opening size. When the animal's bite force is too great or the structure fails and is damaged, causing the top opening and closing claw 403d and the bottom opening and closing claw 403d to suddenly lose their supporting force, the metal tube 404e will press against the oil inside the inner partition 404d and push the oil to flow. The extension tube 404c will push the oil inside the outer partition 404b, and when the oil flows, it will have a hydraulic buffering effect to slow down the approach speed between the top opening and closing claw 403d and the bottom opening and closing claw 403d.

[0046] Example 2, reference Figure 1-7 , an adjustable oral opening structure for animal husbandry and veterinary medicine also includes an adjustment frame 3, wherein the adjustment frame 3 includes a longitudinal slide frame 301, the outer side of the longitudinal slide frame 301 is slidably connected to a transverse slide frame 302, the outer side of the transverse slide frame 302 is slidably connected to a vertical slide frame 303, and the outer side of the vertical slide frame 303 is slidably connected to a ferrule 20;

[0047] By setting the pedal 1 as the installation and placement position of the structure, it can also be used as a positioning point for livestock animals to step on or for the front hooves of larger livestock animals to rest on. Before opening the animal's mouth, the telescopic end of the electric cylinder 7 can be extended along the end frame 6, and the connected sliding sleeve 8 will move closer to each other along the suspension 5. The two groups of sliding sleeves 8 and the connecting frame 9 and the head and neck frame 10 connected at the bottom will approach the animal's head and contact the neck or both sides of the head to assist in fixing the head position, reducing the range of movement of the animal's head. By setting the longitudinal sliding frame 301, it is convenient to adjust the left and right movement of the opening assembly 4. The transverse sliding frame 302 is used to limit and support the front and back movement of the opening assembly 4. The vertical sliding frame 303 can facilitate the adjustment of the vertical position of the opening assembly 4 to facilitate the adjustment of the structural position according to the height of different animal heads.

[0048] Among them, a driving frame 21 is fixedly connected to the front side of the pedal 1. A lead screw 22 is rotatably connected to the inner side of the driving frame 21. The right side of the lead screw 22 is externally connected to a control motor. A driving block 23 is threadedly connected to the outer side of the lead screw 22. The top of the driving block 23 is fixedly connected to the suspension 5. By setting the driving frame 21 in cooperation with the lead screw 22, it is convenient to drive the lead screw 22 to rotate through an external control motor, thereby driving the driving block 23 to move horizontally along the driving frame 21 to adjust the position of the suspension 5 according to the position of the animal. Side bars 24 are fixedly connected to both the front and rear sides of the top of the pedal 1. A driven frame 25 is fixedly connected to the rear side of the pedal 1. A driven block 26 is slidably connected to the inner side of the driven frame 25. The top of the driven block 26 is fixedly connected to the suspension 5. By setting the side bars 24, they are used to block the sides of the animal to limit the range of movement of the animal. The arranged driven block 26 sliding inside the driven frame 25 can facilitate the limiting and auxiliary support of the movement of the suspension 5.

[0049] The working principle of this embodiment: When in use, the animal can be led to the pedal 1 and step on the pedal 1 under the limitation of the side bars 24. The weight of the animal itself can fix the device. Before opening the animal's mouth, the lead screw 22 is driven to rotate through an external control motor, thereby driving the driving block 23 to move horizontally along the driving frame 21 to adjust the position of the suspension 5 according to the position of the animal. The telescopic end of the electric cylinder 7 is extended along the end frame 6, and the connected sliding sleeve 8 will move closer to each other along the suspension 5. The two groups of sliding sleeves 8 and the connecting frame 9 and the head and neck frame 10 connected at the bottom will approach the animal's head and contact the neck or both sides of the head to assist in fixing the head position, reducing the range of movement of the animal's head. The longitudinal sliding frame 301 can facilitate the adjustment of the left and right movement of the opening assembly 4. The transverse sliding frame 302 is used to limit and support the front and back movement of the opening assembly 4. The vertical sliding frame 303 can facilitate the adjustment of the vertical position of the opening assembly 4 to facilitate the adjustment of the structural position according to the height of different animal heads.
