Description

Technical Field

[0001] The present invention relates to the technical field of livestock inspection, and particularly relates to a handheld positioning and clamping tool for livestock veterinary diagnosis and inspection. Background Art

[0002] Animal husbandry refers to the production process of using the physiological functions of animals such as livestock and poultry that have been artificially domesticated by humans, or wild animals such as deer, musk deer, foxes, minks, otters, and quails, through artificial breeding and reproduction, so that they can convert plant energy such as forage and feed into animal energy to obtain livestock products such as meat, eggs, milk, wool, cashmere, hides, silk, and medicinal materials.

[0003] In today's livestock field, raising cattle and sheep accounts for an important part. During the breeding process of cattle and sheep, since young cattle and sheep have relatively low resistance, they often need to be physically examined. When being examined, cattle and sheep may move around, and need to be fixed. The existing methods are to fix the animals on a special fixing table. This has the following problems. Firstly, it is inconvenient to catch the animals. Secondly, during the fixing process, the animals will be very obviously frightened and move around, making the fixing process inconvenient. Therefore, in view of this problem, an improvement is made, and a handheld positioning and clamping tool for livestock veterinary diagnosis and inspection is proposed. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a handheld positioning and clamping tool for livestock veterinary diagnosis and inspection.

[0005] A handheld positioning and clamping tool for livestock veterinary diagnosis and inspection proposed by the present invention includes a first rack and a second rack that are mirror-symmetrical. The first rack and the second rack are connected by an intermediate column and a pair of fixing columns. The pair of fixing columns are symmetrically distributed on both sides of the intermediate column. A pair of first clamping rods and second clamping rods that can rotate around the intermediate column are provided on the intermediate column. The tops of the two first clamping rods are jointly fixed with a first handle, and the tops of the two second clamping rods are jointly fixed with a second handle. Side plates are provided on the opposite sides of the first rack and the second rack, and leg fixing components are provided on the side plates. A head fixing component is provided at the top of the first rack; both hands can hold the first handle and the second handle respectively to lift the entire tool, then move the tool above the animal, and then move the tool downward after spreading the first clamping rod and the second clamping rod with both hands. When the first clamping rod and the second clamping rod are respectively located on the sides of the animal's body, the animal's body can be clamped by controlling the first clamping rod and the second clamping rod with both hands, and in this way, the animal has been basically controlled. Then, only the legs of the animal need to be fixed one by one through the leg fixing component, and then the head of the animal is fixed through the head fixing component. In this way, when examining, the tool can be horizontally placed on the ground, and the animal can be adjusted to maintain a side-lying or lying-flat posture, so as to facilitate the veterinarian to conduct examinations from multiple angles.

[0006] Preferably, the leg fixing assembly includes a U-shaped leg sleeve passing through the side plate. A connecting plate is fixedly connected to both ends of the leg sleeve. A lead screw threadedly connected to the connecting plate is rotatably connected to the outside of the side plate. A turning handle is fixed to the end of the lead screw. Place the animal's leg into the leg sleeve, and then rotate the lead screw by turning the turning handle. The lead screw will gradually tighten the leg sleeve towards the side plate, thereby fixing the leg.

[0007] Preferably, both the middle column and the fixed column are fixedly connected to the second rod. The first clamping rod and the second clamping rod are both rotatably connected to the middle column.

[0008] Preferably, the ends of both the middle column and the fixed column pass through the second rod. A first nut and a second nut for pressing against both sides of the second rod are threadedly connected to one end of the middle column close to the second rod. The first clamping rod and the second clamping rod are both sleeved on the middle column. First, rotate the first nut towards the first rod, then move the second rod, the first clamping rod and the second clamping rod along the middle column towards the first rod, and finally rotate the second nut towards the second rod until it presses against the second rod. In this way, the length between the first rod and the second rod can be adjusted, so that it can be used for smaller animals.

[0009] Preferably, a shaft rod is rotatably connected to both the first rod and the second rod. Synchronous wheels are fixedly sleeved on the adjacent ends of the shaft rod and the lead screw. The two synchronous wheels in the same group are connected by a synchronous belt. When one of the lead screws is rotated, the shaft rod can be driven to rotate through the transmission cooperation of the synchronous wheels and the synchronous belt, and then the other lead screw can be driven to rotate by the shaft rod. In this way, both the front legs or the hind legs of the animal can be fixed at the same time, making the operation of the tool more convenient.

[0010] Preferably, the head fixing assembly includes a U-shaped head sleeve. A pair of round holes for inserting the head sleeve are provided at the top of the first rod. A handle is fixed to the top end of the head sleeve. The head sleeve is connected with a positioning assembly. Place the animal's head between the first rod and the head sleeve, and then lift the head sleeve upward until the head sleeve and the first rod cooperate to fix the animal's neck, thereby fixing its head. Finally, fix the head sleeve at this position through the positioning assembly.

[0011] Preferably, the positioning assembly includes a pair of ear seats fixed to the top of the first rod. An insertion rod passes through between the two ear seats. A plurality of groups of insertion holes for the insertion rod to pass through are evenly distributed up and down on the head sleeve. After lifting the head sleeve to a suitable position, insert the insertion rod between the two ear seats and make the insertion rod insert into a corresponding insertion hole, and the head sleeve can be fixed at this position.

[0012] Preferably, the positioning component includes a U-shaped push rod that is slidably connected to the first rod and supports the bottom of the headgear. The push rod is connected to a lifting structure. By lifting the push rod through the lifting structure, the push rod will then synchronously lift the headgear upward, thereby finally fixing the headgear in a proper position.

[0013] Preferably, the lifting structure includes a pair of bearing seats fixed on the inner side surface of the push rod. A shaft column is rotatably connected to the bearing seats. The top end of the shaft column passes through the push rod and is rotatably connected to the first rod. Conical gears are fixedly sleeved on the adjacent ends of the shaft column and the shaft rod. The two conical gears in the same group are meshed and connected. When the shaft rod rotates, it will drive the shaft column to rotate through the meshing transmission of the two conical gears. Then the shaft column will lift the push rod upward and fix it in a proper position.

[0014] Preferably, the lifting structure includes a pair of ear blocks fixed on the inner side surface of the push rod. A pulling rope is fixed to the top end of the ear block. The other end of the pulling rope passes through the push rod and is fixed on a reel. Both reels are fixedly sleeved on the shaft rod. A pair of hanging posts for hanging the pulling rope are rotatably connected to the inner side surface of the first rod. A guide sleeve is fixed on one side of the first rod. A stop rod is inserted into the guide sleeve. A guide post is inserted into the back surface of the stop rod. The bottom end of the guide post is fixedly connected to the guide sleeve. A spring is sleeved on the guide post. Both ends of the spring are fixedly connected to the guide sleeve and the stop rod respectively. A ratchet wheel is fixedly sleeved on the shaft rod. The bottom end of the stop rod can be inserted into the tooth gap of the ratchet wheel. When the shaft rod rotates, it will synchronously drive the reel to rotate. Then the reel will gradually wind up the pulling rope. The push rod can be lifted upward by the other end of the pulling rope. And when the shaft rod rotates forward, it will synchronously drive the ratchet wheel to rotate. The teeth of the ratchet wheel will push the stop rod upward. In this way, the forward rotation of the shaft rod will not be affected. On the contrary, due to the restriction of the stop rod, the ratchet wheel cannot rotate backward. Thus, the headgear is fixed in a proper position. When it is necessary to rotate the shaft rod backward, just lift the stop rod upward and then rotate the shaft rod.

[0015] Compared with the prior art, the present invention provides a handheld positioning and clamping tool for livestock and veterinary diagnosis and examination, having the following beneficial effects:

[0016] 1. For a handheld positioning and clamping tool for livestock and veterinary diagnosis and examination, by setting the first clamping rod and the second clamping rod, the animal's body can be first clamped by controlling the first clamping rod and the second clamping rod with both hands, so that the animal is basically controlled. Then, the legs of the animal are fixed one by one through the leg fixing component. Then, the head of the animal is fixed through the head fixing component. Thus, the process of fixing the animal becomes much more convenient.

[0017] 2. A handheld positioning and clamping tool for livestock and veterinary diagnosis and examination. By setting a synchronous pulley, when one of the lead screws is rotated, the shaft can be driven to rotate through the transmission cooperation of the synchronous pulley and the synchronous belt, and then the other lead screw can be driven to rotate by the shaft. In this way, the two front legs or hind legs of the animal can be fixed simultaneously, making the operation of the tool more convenient.

[0018] 3. A handheld positioning and clamping tool for livestock and veterinary diagnosis and examination. By setting a lifting structure and a push rod, when fixing the front legs, the push rod can be lifted upward through the lifting structure, and then the push rod will synchronously lift the headgear upward, finally fixing the headgear in a suitable position. In this way, the two front legs and the head of the animal can be fixed simultaneously. Brief Description of the Drawings
