DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the utility model more clear, the utility model is clearly and completely described below in conjunction with specific embodiments.

[0030] Embodiment 1:

[0031] like Figure 1-Figure 4 The one-handed bull nose pliers shown in the figure include a first pliers handle 1 and a second pliers handle 5, wherein the first pliers handle 1 is L-shaped, including a first connecting portion 101 and a first gripping portion 102, and the second pliers handle 5 is L-shaped, including a third connecting portion 501 and a second gripping portion 502, the first pliers handle 1 and the second pliers handle 5 are arranged opposite to each other, and the free end of the second gripping portion 502 is hinged to the turning point of the first pliers handle 1; the first connecting portion 101 and the third connecting portion 501 are respectively connected to the first pliers mouth 3 and the second pliers mouth 9 arranged opposite to each other.

[0032] In this embodiment, the first gripping portion 102 is located on the inner side of the second gripping portion 502, and the length of the first gripping portion 102 is smaller than that of the second gripping portion 502. The free ends of the second gripping portion 502 are provided with bending portions 503 perpendicularly facing inward. The free ends of the bending portions 503 are fixed with a U-shaped hinge seat 6, and the hinge seat 6 is provided with a second through hole 7. The turning point of the first clamp handle 1 is the connection point between the first connecting portion 101 and the first gripping portion 102. The turning point of the first clamp handle 1 is provided with a first through hole 2 corresponding to the second through hole 7. The first through hole 2 and the second through hole 7 are provided with a pin shaft 8, and the first clamp handle 1 and the second clamp handle 5 are hinged together by the pin shaft 8.

[0033] The free ends (outer ends) of the first jaw 3 and the second jaw 9 are provided with ball heads 11 for protecting the cow's nose and preventing the jaws from causing damage to the cow's nose. As a further optimization, a rubber or silicone sheath is provided on the ball head 11.

[0034] The first jaw 3 and the second jaw 9 are arc-shaped (V-shaped, C-shaped or U-shaped, etc.) and the openings are arranged opposite to each other. The first jaw 3 is connected to the first connecting part 101 through the second connecting part 4, and the second jaw 9 is connected to the third connecting part 501 through the fourth connecting part 10. In this embodiment, the first jaw 3 and the second jaw 9 are C-shaped, the first jaw 3 and the second connecting part 4 are S-shaped as a whole, and the second jaw 9 and the fourth connecting part 10 are inverted S-shaped as a whole. When the outer ends of the first jaw 3 and the second jaw 9 are in contact with each other, the inner ends of the first jaw 3 and the second jaw 9 are also in contact with each other to form a bayonet 20, so that the bull nose pliers are not easily deformed, are firm and strong, and have higher overall structural strength.

[0035] The one-handed bull nose pliers provided by the utility model have a simple structure and an ingenious design. By pulling the first gripping portion 102 with one hand to close the first gripping portion 102 and the second gripping portion 502, the outer ends of the first jaw 3 and the second jaw 9 can clamp the bull's nose to achieve the function of controlling the bull. When restraining the bull, only the first gripping portion 102 and the second gripping portion 502 need to be held with one hand, and fatigue is not easily caused by holding for a long time. After holding tightly, the hand is restricted inside the first clamp handle 1 and the second clamp handle 5, and the hand will not slip out of the hand. The utility model has good practicality, and the bull's horns can be controlled with one hand and the bull's nose can be controlled with the other hand, which greatly facilitates the work of veterinarians.

[0036] Embodiment 2:

[0037] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that a clamping head mechanism is arranged between the inner ends (at the clamping opening 20) of the first jaw 3 and the second jaw 9, and the clamping head mechanism includes two outer clamping blocks 18 arranged on the first jaw 3 and an inner clamping block 19 arranged on the second jaw 9 and adapted to the two outer clamping blocks 18, or the clamping head mechanism includes two outer clamping blocks 18 arranged on the second jaw 9 and an inner clamping block 19 arranged on the first jaw 3 and adapted to the two outer clamping blocks 18. When the first jaw 3 and the second jaw 9 are closed, the inner clamping block 19 is just located between the two outer clamping blocks 18, and the inner clamping block 19 and the outer clamping block 18 play a guiding and limiting role. When the outer ends of the first jaw 3 and the second jaw 9 clamp the bull's nose, as the bull's head twists, the first jaw 3 and the second jaw 9 will shake relative to each other, causing the overall structure of the bull's nose pliers to deform, which is inconvenient to use. By setting a clamping head mechanism, the relative shaking between the first jaw 3 and the second jaw 9 can be avoided, thereby enhancing the stability and practicality of the overall structure of the bull's nose pliers. In this embodiment, the outer clamping block 18 is arranged on the first jaw 3, and the inner clamping block 19 is arranged on the second jaw 9.

[0038] Embodiment 3:

[0039] like Figure 6 and Figure 7 As shown, the difference between this embodiment and the embodiments 1 and 2 is that a limit baffle 601 is provided on the outer side of the bottom of the hinge seat 6. The limit baffle 601 is provided to limit the maximum rotation angle of the first gripping portion 102 relative to the second gripping portion 502. When the first jaw 3 and the second jaw 9 are fully opened, it is convenient for a person to hold the first gripping portion 102 and the second gripping portion 502 with one hand at the same time, so that the first jaw 3 and the second jaw 9 are closed, and it is prevented that the first gripping portion 102 and the second gripping portion 502 are difficult to be held by one hand due to excessive rotation angle, which greatly enhances the practicality of the product.

[0040] Embodiment 4:

[0041] like Figure 8 and Fig. 9 As shown, the difference between this embodiment and embodiment 1 is that: a threaded hole 12 is provided at the connection between the first jaw 3 and the second connecting portion 4, and the axis of the threaded hole 12 is parallel to the length direction of the first gripping portion 102, or,

[0042] A threaded hole 12 is provided at the connection between the second jaw 9 and the fourth connecting portion 10, and the axis of the threaded hole 12 is parallel to the length direction of the second gripping portion 502;

[0043] A bolt 13 is threadedly connected in the threaded hole 12 , and a rotating handle 14 is provided at the outer end of the bolt 13 .

[0044] In this embodiment, the threaded hole 12 is provided at the connection between the second jaw 9 and the fourth connecting portion 10 , and the inner end of the bolt 13 faces the connection between the first jaw 3 and the second connecting portion 4 .

[0045] For cows of different sizes, by setting the rotating handle 14 and the bolt 13, the minimum distance between the outer ends of the first jaw 3 and the second jaw 9 can be adjusted, so as to accurately control the clamping force of the nose pliers to prevent the clamping force from being too small, causing the cow's nose to slip out of the nose pliers, or the clamping force from being too large, causing the cow to be in a state of resistance, or even causing damage to the cow's nose.

[0046] Embodiment 5:

[0047] like Fig.10 As shown, the difference between this embodiment and embodiment 4 is that the clamping head mechanism described in embodiment 2 is additionally provided, the threaded hole 12 passes through the inner clamping block 19, and the inner end of the bolt 13 cooperates with the two outer clamping blocks 18 to play a guiding and limiting role.

[0048] Embodiment 6:

[0049] like Figure 8 and Fig. 9As shown, the difference between this embodiment and embodiment 1 is that: two limiting rings 15 are fixedly provided on the third connecting portion 501, a damping sleeve 16 made of rubber or silicone material is sleeved between the two limiting rings 15 on the third connecting portion 501, and a stopper 17 is fixedly provided on the damping sleeve 16; when the first jaw 3 and the second jaw 9 are completely closed, the stopper 17 can be blocked on the inner side of the free end of the first gripping portion 102 by rotating the damping sleeve 16.

[0050] The present embodiment is used to restrain cattle of the same size. After the first jaw 3 and the second jaw 9 clamp the cattle's nose, the first gripping portion 102 and the second gripping portion 502 are just merged together. At this time, by rotating the damping sleeve 16, the stopper 17 can limit the free end of the first gripping portion 102. At this time, there is no need to hold it tightly, and the first gripping portion 102 and the second gripping portion 502 will not separate, so that the cattle nose pliers can be effectively fixed, saving manpower.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
