[0002] Animal husbandry refers to the production process of using the physiological functions of domesticated animals such as livestock and poultry, or wild animals such as deer, musk deer, fox, mink, otter, quail, etc., to convert plant energy such as forage and feed into animal energy through artificial breeding and reproduction, so as to obtain livestock products such as meat, eggs, milk, wool, cashmere, hides, silk and medicinal materials. In the breeding of livestock, it is necessary to treat the livestock, such as examining the oral cavity of the livestock, or administering drugs or gastric lavage to the livestock. These treatments all require the oral cavity of the livestock to be opened, so an oral opening device is needed.

[0003] For example, the patent document with the announcement number CN219423046U discloses a mouth-opening device for livestock and veterinary medicine. When using the device, the device is inserted into the mouth of the livestock, and then the electric push rod is started. The electric push rod drives the slider to move inside the slideway, which can increase the distance between the upper top plate and the lower pad, thereby opening the mouth of the livestock. However, since the electric push rod is arranged vertically, the distance between the upper top plate and the lower pad of the device in the initial state is large, that is, the thickness of the device is large, so the mouth of the livestock needs to be opened to a certain extent before the device can be inserted, and the livestock generally resists, which makes it difficult to open the mouth of the livestock, so the device is relatively inconvenient to use.

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 6As shown, a livestock oral opening device comprises a grip rod 1, and opening mechanisms 2 are arranged on both sides of the grip rod 1 for opening the upper and lower jaws of livestock. A cone head 3 is rotatably connected to the rear end of the grip rod 1, and the tip of the cone head 3 faces backwards. A threaded groove 301 is provided on the surface of the cone head 3. A rotating mechanism 4 is rotatably installed in the grip rod 1, and the rotating mechanism 4 is used to drive the cone head 3 to rotate. When in use, the veterinarian inserts the tip of the cone head 3 between the upper and lower teeth of the livestock, and drives the cone head 3 to rotate through the rotating mechanism 4. By utilizing the cooperation between the threaded groove 301 and the teeth, the cone head 3 can gradually extend into the livestock's oral cavity when it rotates. , so that the upper and lower teeth of the livestock are gradually opened, so that the mouth-opening mechanism 2 can enter the livestock's oral cavity conveniently. A through groove 101 is provided on the grip rod 1, and the through groove 101 extends along the axial direction of the grip rod 1 and penetrates along the radial direction of the grip rod 1. A movable block 5 is slidably connected in the through groove 101, and a control mechanism 6 is installed on the movable block 5. The movable block 5 is used to drive the control mechanism 6 to move forward and backward. When the cone head 3 opens the livestock's teeth, the control mechanism 6 is moved by the movement of the movable block 5, and then the control mechanism 6 drives the mouth-opening mechanism 2 to extend into the livestock's oral cavity. The control mechanism 6 is used to drive the mouth-opening mechanism 2 to open the livestock's oral cavity.

[0026] The rotating mechanism 4 includes a rotating rod 401 and a first rotating handle 402. The rotating rod 401 is connected to the inside of the grip 1 through a bearing. The rotating rod 401 is coaxial with the grip 1. The rotating rod 401 passes through the grip 1 from front to back. The rear end of the rotating rod 401 is fixedly connected to the conical head 3. The conical head 3 is driven to rotate by the rotation of the first rotating handle 402. The first rotating handle 402 is fixedly connected to the front end of the rotating rod 401, and the rotating rod 401 passes through the middle of the movable block 5.

[0027] The rotating rod 401 is a threaded rod, and the rotating rod 401 is connected to the movable block 5 by a thread. In this way, when the rotating rod 401 drives the cone head 3 to rotate, the rotating rod 401 can also drive the movable block 5 to move. Therefore, when the cone head 3 gradually squeezes the teeth of the livestock, the movable block 5 drives the control mechanism 6 and the mouth-opening mechanism 2 to gradually approach the livestock's mouth. After the cone head 3 squeezes the teeth, the mouth-opening mechanism 2 can enter the livestock's oral cavity by continuing to rotate the rotating rod 401. Therefore, the veterinarian only needs to hold the gripping rod 1 with one hand and rotate the rotating rod 401 with the other hand to conveniently send the mouth-opening mechanism 2 into the livestock's oral cavity. In addition, the threaded connection between the rotating rod 401 and the movable block 5 can stabilize the position of the movable block 5, and the mouth-opening mechanism 2 can be prevented from moving randomly after entering the oral cavity. Guide grooves 102 are provided on both sides of the through groove 101, and protrusions extend from both sides of the movable block 5. The movable block 5 slides with the guide grooves 102 through the protrusions.

[0028] The control mechanism 6 includes a frame 601, which is sleeved on the outside of the handle 1. A vertically arranged bidirectional screw rod 602 is connected to the frame 601 through a bearing. Two lifting blocks 603 symmetrically arranged up and down are threadedly connected to the bidirectional screw rod 602. The two lifting blocks 603 are respectively located on the upper and lower sides of the handle 1. A second turning handle 604 is fixedly connected to the top of the bidirectional screw rod 602. The bidirectional screw rod 602 passes through the movable block 5 and is connected to the movable block 5 through a bearing. The movable block 5 drives the frame 601 to move through the bidirectional screw rod 602, thereby moving the control mechanism 6 as a whole.

[0029] The mouth-opening mechanism 2 comprises an upper support plate 201 and a lower support plate 202, and two of the upper support plates 201 and the lower support plates 202 are provided and are distributed on both sides of the gripping rod 1. The upper support plate 201 and the lower support plate 202 are connected with extension rods 203 by screws, and the screws can be used to facilitate the disassembly and replacement of the lower support plate 202. The upper and lower groups of extension rods 203 are respectively fixedly connected to the upper and lower lifting blocks 603. Rectangular grooves extending in the vertical direction are provided on both sides of the frame 601. The extension rods 203 pass through the rectangular grooves and are attached to the inner walls of the rectangular grooves. The rectangular grooves can guide the up and down movement of the extension rods 203. When the bidirectional screw rod 602 rotates, it will drive the two lifting blocks 603 away from each other. The lifting blocks 603 drive the upper and lower groups of extension rods 203 away from each other, thereby moving the upper support plate 201 and the lower support plate 202 away, so that the livestock's mouth can be opened.

[0030] A slide bar 605 arranged in the vertical direction is fixedly connected inside the frame 601, and the lifting block 603 is slidably connected to the slide bar 605. The slide bar 605 passes through the movable block 5. The slide bar 605 can make the movement of the lifting block 603 more stable.

[0031] Working principle: When in use, the veterinarian inserts the tip of the conical head 3 between the upper and lower teeth of the livestock, and rotates the rotating rod 401 through the first turning handle 402, and the rotating rod 401 drives the conical head 3 to rotate, and utilizes the cooperation between the thread groove 301 and the livestock's teeth. When the conical head 3 rotates, it can gradually extend into the livestock's oral cavity, so that the upper and lower teeth of the livestock are gradually opened. When the rotating rod 401 rotates, it will drive the movable block 5 to move backward, and the movable block 5 drives the control mechanism 6 and the mouth-opening mechanism 2 to move backward. After the conical head 3 squeezes the teeth open, the mouth-opening mechanism 2 can gradually enter the livestock's oral cavity by continuing to rotate the rotating rod 401, and then the two-way screw rod 602 is rotated through the second turning handle 604. The two-way screw rod 602 drives the upper and lower lifting blocks 603 to move away from each other, and the lifting block 603 drives the extension rod 203 to move up and down, so that the upper support plate 201 and the lower support plate 202 move away from each other, thereby opening the livestock's mouth.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
