[0048] Example 1

[0049] like Figure 1-3 As shown, the utility model provides a branch binding buckle, comprising a ring body 91 and a connecting seat 92, wherein the ring body 91 is provided with a notch 911, and the crop branches or vines to be bound are placed into the ring body 91 through the notch 911;

[0050] A slot 93 is provided on the connection seat 92. The connection seat 92 is a U-shaped structure with an opening facing upward. A slot 93 for accommodating and clamping the wire 10 is provided at the bottom of the connection seat 92. The wire 10 is squeezed into the slot 93, and then the branches or vines of the crops are hung on the wire 10 through the branch binding buckle 9.

[0051] like Figure 3 As shown, in order to strengthen the fixing effect of the branch binding buckle 9 and the iron wire 10, it is usually necessary to set the length of the connecting seat 92 to be long enough, increase the force-bearing area of ​​the connecting seat 92 and the iron wire 10, and make the branches or vines of the crops firmly hang on the iron wire 10; at the same time, as the branches and leaves of the crops gradually grow luxuriantly, the force of the crops on the branch binding buckle 9 increases. In order to prevent the iron wire 10 from slipping out of the card slot 93, the iron wire 10 needs to be firmly fixed in the said card slot 93; for this, by providing an undercut 94 on the inner side wall of the connecting seat 92, when the iron wire 10 is stuck After entering the slot 93, it is located below the undercut 94, and the undercut 94 can be a wedge-shaped structure or other similar structures; further, the undercut 94 can be arranged on one of the inner side walls of the U-shaped connecting seat 92, or the undercut 94 can be arranged on both inner side walls of the U-shaped connecting seat 92; further, there can be one undercut 94, or more than one undercut 94; wherein, the multiple undercuts 94 can be arranged vertically from top to bottom, or horizontally from left to right, or arranged in an array, and there are gaps between each undercut 94.

[0052] The wedge-shaped undercut 94 facilitates the iron wire 10 to be pressed into the slot 93 and prevents the iron wire 10 from being separated from the connecting seat 92;

[0053] Furthermore, in order to facilitate the fingers to apply force to press the wire 10 into the slot 93, a pressing surface is set on the bottom surface of the connecting seat 92, and the pressing surface can be a flat surface or a curved surface. The flat or curved pressing surface increases the pressing area of ​​the fingers, thereby improving the operator's pressing comfort and helping to improve work efficiency.

[0054] like Figure 2-3 As shown, the pressing surface provided in this embodiment is a convex curved surface 924, and the convex curved surface 924 contacts and cooperates with the pressing finger to improve the comfort of the finger applying force.

[0055] like Figure 2 and Figure 4As shown, in order to facilitate injection molding, an opening 923 is provided through the pressing surface.

[0056] Furthermore, the ring body 91 is in the shape of a spiral line, and a notch 911 is formed at the overlap of the spiral line. The spiral ring body 91 can easily put the crops into the ring body 91, and can prevent the crops from slipping out of the ring body 91 from the notch 911. Furthermore, in order to prevent the ring body 91 from scratching the crops, a flat surface is provided on the inner side of the ring body 91, and the flat surface contacts the crops, and the ring body 91 is prevented from scratching the branches or vines of the crops to be tied by increasing the contact area; the flat surface can be formed by reducing the material, such as cutting the inner side of the ring body 91, or by adding the material, for example, the flange 912 is formed on the inner side of the ring body 91 by adding the material, and the surface of the flange 912 in contact with the crops is a flat surface; further, in order to improve the strength of the ring body 91, the height of the flange 912 can be set to be greater than the height of the ring body 91.

[0057] like Figure 3-4 As shown, in order to adapt to different models of iron wires 10, a plurality of slots with different calibers are provided. The slot 93 includes a first slot 93a and a second slot 93b which are sequentially opened from top to bottom. The first slot 93a and the second slot 93b have different calibers. Specifically, the caliber of the first slot 93a is usually set to be larger than the caliber of the second slot 93b.

[0058] In order to facilitate the smooth pressing of the iron wire 10 into the card slot 93, as shown in FIG. Figure 3 As shown, a guide surface 1 921 and a guide surface 2 922 are respectively provided on the top of the inner side wall of the connecting seat 92. The guide surface 1 921 and the guide surface 2 922 are arranged opposite to each other and form a guide channel for guiding the iron wire 10 to enter the slot 93. The opening of the guide channel gradually decreases from top to bottom. Specifically, the opening of the guide channel is funnel-shaped. The guide surface 1 921 and the guide surface 2 922 can be inclined surfaces or inclined surfaces. The guide surface 921 guides the iron wire 10 to enter the slot 93, so that the iron wire 10 can be quickly aligned with the slot 93.

[0059] The branch binding buckle 9 is made of an elastic plastic material, for example, PP, PE or nylon or other plastic materials can be selected; for plastic parts, injection molding is usually used.

[0060] like Figure 1-3As shown, when tying crops, first place the branch tying buckle 9 under the iron wire 10 to be inserted, and the guide surface 1 921 and the guide surface 2 922 form a guide channel for guiding the iron wire 10 to enter the slot 93. One finger contacts the convex curved surface 924, and one finger contacts the iron wire 10. The two fingers apply force at the same time, and the iron wire 10 is inserted into the slot 93 through the guide channel. Then, the branches or vines of the crops to be tied are placed into the ring body 91 through the notch 911 to complete the fixation of the branches or vines of the crops.

[0061] Example 2

[0062] Different from Example 1, Figure 4 As shown, the branch binding buckle 9 provided in this embodiment has a bottom pressing surface of its connecting seat 92 which is a concave curved surface 925. The concave curved surface 925 contacts and cooperates with the pressing finger, thereby improving the comfort of the finger applying force.

[0063] Example 3

[0064] Different from the first and second embodiments, the branch tying buckle 9 provided in the present embodiment has a bottom of a connecting seat 92 arranged in an arc shape. In order to improve the clamping efficiency between the branch tying buckle 9 and the iron wire 10, the branch tying buckle 9 provided in the present embodiment is used in conjunction with a special branch tying clamp, and the bottom of the connecting seat 92 is arranged in an arc shape, so as to facilitate the clamping of the connecting seat 92 into the receiving groove 12 of the branch tying clamp;

[0065] Furthermore, the present embodiment also provides a branch binding caliper, by operating the branch binding caliper to press the wire 10 into the connecting seat 92 of the branch binding buckle 9, instead of the operator's fingers applying force to clamp the branch binding ring 9 into the wire 10, thereby improving production efficiency.

[0066] like Figure 5-8 As shown, the branch tying caliper comprises a first clamp arm 2 and a second clamp arm 5, which are rotatably connected and hinged at the front of the first clamp arm 2 and the second clamp arm 5 for labor saving. A first jaw 1 is fixedly connected to the front end of the first clamp arm 2, and a first handle 3 is sleeved at the rear end thereof. A second jaw 4 is fixedly connected to the front end of the second clamp arm 5, and a second handle 6 is sleeved at the rear end thereof; wherein the first jaw 1 is used to fix the branch tying buckle 9, and the second jaw 4 is used to press the iron wire 10 into the branch tying buckle 9.

[0067] In order to fix the branch binding buckle 9 on the first jaw 1, a receiving groove 12 is provided at the front part of the first jaw 1, and the receiving groove 12 extends forward to form a placement seat 13, and the front part of the placement seat 13 extends to the left and right sides, and an upwardly extending limiting portion 14 is also provided at the front end of the placement seat 13, wherein the receiving groove 12 and the placement seat 13 are used to place the branch binding buckle 9, and the limiting portion 14 contacts the outer side of the ring body 91 of the branch binding buckle 9; the branch binding buckle 9 is clamped and fixed by the limiting portion 14 and the receiving groove 12; the second jaw 4 is connected to the front end of the second clamp arm 5, and the second jaw 4 is used to press the iron wire 10 into the branch binding buckle 9.

[0069] When in use, in order to prevent the branch binding buckle 9 from shaking, the ring body 91 of the branch binding buckle 9 is placed on the placement seat 13, and the front part of the placement seat 13 extends to the left and right sides. By increasing the area of ​​the placement seat 13, the supporting force exerted on the ring body 91 is more uniform, thereby improving the supporting effect of the placement seat 13. Furthermore, the surface shape of the placement seat 13 can be a plane, and can also be set to an arc surface structure that matches the ring body 91 of the branch binding buckle 9. In order to prevent the branch binding buckle 9 from moving when the second jaw 4 is pressed down, the branch binding buckle 9 is placed between the guide member 11 and the limiting portion 14. The limiting portion 14 is arranged to extend upward at the front end of the placement seat 13, and contacts with the outer side of the ring body 91 through the limiting portion 14, thereby limiting the movement of the ring body 91 away from the guide member 11. The limiting portion 14 can be made of elastic material, and a recess is provided on the side where the limiting portion 14 contacts the ring body 91, and the recess is engaged with the outer wall of the ring body 91. Then, when the branch binding buckle 9 is placed in the first jaw 1, the branch binding buckle 9 is clamped and fixed through the limiting portion 14 and the accommodating groove 12.

When the branch-binding buckle 9 is placed on the placement seat 13, the flared opening 151 plays a guiding and limiting role, facilitating the branch-binding buckle 9 to quickly align with the accommodating groove 12 and snap into the concave portion of the limiting portion 14. The strip-shaped notch 152 is provided for placing the wire 10. On the one hand, it can guide the wire 10 to align with the snap-in groove 93 of the branch-binding buckle 9, and on the other hand, it can prevent the wire 10 from moving when the second jaw 4 is pressed down.

[0071] Furthermore, in order to prevent the wire 10 from moving, a downward pressing groove 42 is provided at the bottom of the second jaw 4, and the downward pressing groove 42 is used to accommodate the wire 10; Figure 5-7 As shown, when the hands tightly press the first handle 3 and the second handle 6, the iron wire 10 rests on the front surface of the guide 11. When the second jaw 4 moves downward, the iron wire 10 is first inserted into the lower pressing groove 42. Under the action of the lower pressing groove 42, the iron wire 10 is pressed into the slot 93 of the branch binding buckle 9. In order to facilitate the fixing of the iron wire 10, the lower pressing groove 42 can be an arc-shaped or "V"-shaped groove.

[0072] A torsion spring 7 is connected to the hinge of the first clamp arm 2 and the second clamp arm 5, one end of the torsion spring 7 is fixedly connected to the first clamp arm 2, and the other end is fixedly connected to the second clamp arm 5. Under the action of the torsion spring 7, the first jaw 1 and the second jaw 4 are always kept open. When performing binding work, after the wire 10 is inserted into the branch binding buckle 9, the first jaw 1 and the second jaw 4 are automatically opened to prepare for the next pressing. The operator only needs to continuously hold and press the first handle 3 and the second handle 6, and there is no need to apply force to separate the first jaw 1 and the second jaw 4, which has a labor-saving effect.
