DETAILED DESCRIPTION

The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

As shown in Figures 1 to 3, the utility model proposes a drencher for animal husbandry and veterinary medicine, including: a syringe 1, the interior of the syringe 1 is a hollow structure, one end of the syringe 1 is provided with a liquid outlet tube 10 connected to the syringe 1, and the diameter of the liquid outlet tube 10 is smaller than the diameter of the syringe 1; the other end is provided with an opening, and a pressing part 13 is provided at the opening. As shown in Figure 1, the pressing part 13 is two pressing pieces fixed and symmetrically arranged on the outside of the opening. A piston (not shown in the figure) is slidably provided inside the syringe 1, and the side wall of the piston is in contact with the inner wall of the syringe 1. A push rod 11 is provided on the side of the piston close to the opening, and the end of the push rod 11 away from the piston extends to the outside of the opening of the syringe 1.

The outside of the syringe 1 is provided with a spreading device 2, and the spreading device 2 is located at one end of the syringe 1 close to the liquid outlet tube 10. The spreading device 2 includes two spreading rods 20, two transmission rods 21, a center plate 22 and a fixed plate 23, the fixed plate 23 is vertically arranged, the two spreading rods 20 are symmetrically arranged at both ends of the fixed plate 23, and one end of the two spreading rods 20 is respectively rotatably connected to the fixed plate 23. Each spreading rod 20 is provided with a bending portion 200; that is, as shown in Figures 1 and 2, the spreading rod 20 is not a straight rod but a bending rod, wherein the bending degree of the bending portion 200 is 130-145 degrees. The other two transmission rods 21 are symmetrically arranged on the inner side of the two spreading rods 20, and each transmission rod 21 is rotatably connected to the bending portion 200 on the corresponding spreading rod 20. The center plate 22 is arranged between the two transmission rods 21, and the other ends of the two transmission rods 21 are rotatably connected to the two ends of the center plate 22 respectively; the fixed plate 23 and the center plate 22 are arranged parallel to each other. A hand-held portion 24 is provided at the lower end of the fixed plate 23 away from the center plate 22. The syringe 1 is passed through the center of the center plate 22 and is clamped with the center plate 22; the liquid outlet pipe 10 above the syringe 1 is located between the two opening rods 20, and the end of the liquid outlet pipe 10 away from the syringe 1 extends to the end of the opening rod 20 away from the fixed plate 23;

When this embodiment is used in practice, first, as shown in FIG. 2 , the expansion device 2 is in a closed state, that is, the ends of the two expansion rods 20 away from the fixed plate 23 are attached to each other, thereby forming a closed state. When the medicine is actually injected, the center plate 22 is first pushed in the direction away from the fixed plate 23, that is, the direction of the arrow in FIG. 2 ; in the process of the distance between the center plate 22 and the fixed plate 23 becoming farther, the transmission rods 21 at both ends of the center plate 22 continuously push the expansion rods 20 to both sides, so that the two expansion rods 20 are in an open state, as shown in FIG. 1 , and then the end of the liquid outlet tube 10 is placed in the liquid medicine, and the piston is pulled outward to fill the syringe 1 with liquid medicine. The principle of the syringe 1 is the same as that of the injection needle in the prior art. After being filled with liquid medicine, the center plate 22 is pushed in the opposite direction to close the expansion rods 20. Then place the opening device 2 in the mouth of the livestock. Since the syringe 1 is clamped with the center plate 22, the syringe 1 can be gently pushed in the direction indicated by the arrow in Figure 2 to move the center plate 22 away from the fixed plate 23, so that the two opening rods 20 are opened and the mouth of the livestock is opened to a certain space. Then push the piston of the syringe 1 to pour the medicine into the mouth of the livestock. The end of the liquid outlet tube 10 away from the syringe 1 extends to the end of the opening rod 20 away from the fixed plate 23, and when the syringe 1 is pushed, the liquid outlet tube 10 on the syringe 1 will also move closer to the livestock's pharynx for a distance, so the medicine will be poured into the deeper position of the livestock's mouth, that is, close to the pharynx, and will not flow out of the mouth.

In another embodiment, the outer side of the spreading rod 20 is set to an arc 201, and one side of the arc 201 is made of soft material to improve its comfort and avoid damaging the mouth of the livestock. In addition, the spreading rod 20 is provided with a terminal 27 at one end away from the fixing plate 23, and a semicircular groove channel 28 is provided on the inner side of the terminal 27. The length direction of the groove channel 28 is parallel to the axial direction of the liquid outlet tube 10; the end of the liquid outlet tube 10 away from the injection barrel 1 extends into the groove channel 28.

In this embodiment, the end of the spreading rod 20 is provided with an end head 27, and the end head 27 is provided with a semicircular groove-shaped channel 28 for the liquid outlet tube 10 to pass through, wherein when the two spreading rods 20 are in a closed state, the two end heads 27 are in surface contact with each other, and the two semicircular groove-shaped channels 28 mutually form a circular channel, and the liquid outlet tube 10 can be placed in the circular channel, and the end of the liquid outlet tube 10 can exceed the distance of one end of the end head 27, that is, when the spreading rod 20 is in a closed state, it is located outside the end head 27, as shown in FIG3. At this time, the liquid outlet tube 10 can be placed in the liquid medicine when the spreading device 2 is not spread, and the injection cylinder 1 is filled with the liquid medicine. In addition, in this embodiment, even if the spreading rod 20 is not in a spread state in the mouth of the livestock, the liquid medicine can be poured into the mouth of the livestock by using the liquid outlet tube 10. The expansion rod 20 in the present application is itself in an arc shape 201, so when the expansion rod 20 is not expanded, the mouth of the livestock can be expanded to a certain space, and the liquid outlet tube 10 can be extended to a position close to the pharynx of the livestock. This embodiment is suitable for some livestock with smaller mouths.

In addition, the center plate 22 is provided with a first through hole 25 for the syringe 1 to pass through, and the fixed plate 23 is provided with a second through hole 26 for the syringe 1 to pass through. A stop ring 12 is provided on the side wall of the syringe 1, and the stop ring 12 is arranged close to the liquid outlet pipe 10. The outer diameter of the stop ring 12 is larger than the diameter of the first through hole 25 and smaller than the diameter of the second through hole 26. In this embodiment, the syringe 1 is slidably connected with the first through hole 25 and the second through hole 26, and the syringe 1 can be removed from the opening device 2 at any time. At the same time, due to the setting of the stop ring 12, after the syringe 1 is inserted into the first through hole 25, the stop ring 12 and the first through hole 25 are engaged. After the syringe 1 is continuously pushed, the center plate 22 can be pushed away from the fixed plate 23, thereby the opening rod 20 is supported.

The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
