[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] An embodiment provided by the present utility model is as follows: As Figure 1 shown, a jujube grafting scion shearing device includes an upper handle 1, a lower handle 2, an auxiliary support spring 3, a first opening and closing connecting member 4, a second opening and closing connecting member 5, a shearing head 6, a shearing seat 7, and a scion fixing mechanism 8.

[0024] As Figure 1 and Figure 2 shown, the first opening and closing connecting member 4 is hingedly connected to the second opening and closing connecting member 5. The first opening and closing connecting member 4 is fixedly connected to the upper handle 1, and the second opening and closing connecting member 5 is fixedly connected to the lower handle 2. The first opening and closing connecting member 4 and the second opening and closing connecting member 5 are in a bent shape, and the central axes of the ends on one side and the other side of the two are not on the same straight line. An auxiliary support spring 3 is arranged between the upper handle 1 and the lower handle 2. A sleeve ring 11 is arranged at the end of the upper handle 1, and the sleeve ring 11 is rotatably connected to the upper handle 1. There is a groove on the outer surface of the end of the lower handle 2, and the sleeve ring 11 corresponds to the position of the groove.

[0025] As Figure 2As shown, one end of the second opening and closing connecting member 5 away from the lower handle 2 is fixedly connected to the cutting head 6, and one end of the first opening and closing connecting member 4 away from the upper handle 1 is fixedly connected to the cutting seat 7. A blade 61 with an inclined angle is arranged at the lower end of the cutting head 6, and a blade groove 71 is arranged above the cutting seat 7. In the cutting state, the blade 61 correspondingly falls into the blade groove 71.

[0026] As Figure 1 and Figure 2 shown, one side of the cutting seat 7 is fixedly connected to the scion fixing mechanism 8. As Figure 3 and Figure 4 shown, the scion fixing mechanism 8 includes a housing 81, a single set of limiting members 82, a left pressing block 83 and a right pressing block 84. A single set of limiting members 82 is arranged inside the housing 81. The single set of limiting members 82 includes a fixing member 821, a compression active spring 822 and a convex block 823. A compression active spring 822 is arranged on one side of the fixing member 821 and abuts against the inner side wall of the housing 81, and a convex block 823 is arranged on the other side of the fixing member 821. The fixing members 821 are distributed in two directions. The convex block 823 of the fixing member 821 in one direction passes through the housing 81 and is connected to the left pressing block 83, and the convex block 823 of the fixing member 821 in the other direction passes through the housing 81 and is connected to the right pressing block 84.

[0027] As Figure 4 and Figure 5 shown, three sets of single set of limiting members 82 are arranged inside the housing 81. The two outer sets of single set of limiting members 82 are in the same direction and are jointly connected to the left pressing block 83 through their convex blocks 823, and the middle set of single set of limiting members 82 is in the opposite direction to the previous two sets and its convex block 823 is connected to the right pressing block 84.

[0028] As Figure 4 shown, through holes are arranged on the vertical surface of the fixing member 821, and spikes 824 are arranged on the inner wall of the through hole side close to the compression active spring 822. Multiple groups of spikes 824 are evenly distributed.

[0029] As Figure 3 shown, the cutting seat 7 is U-shaped, and inclined through holes are opened on both side vertical surfaces. The connection direction of the two inclined through holes is perpendicular to the direction of the blade 61. Positioning rings 72 with the same inclined angle as the inclined through holes are fixedly arranged on the outer side surfaces of the cutting seat 7 at the positions of the two inclined through holes.

[0030] When using the device to shear the jujube grafted scion, the collar 11 is opened, the two groups of limit are cancelled, and under the action of the auxiliary support spring 3, the ends of the upper handle 1 and the lower handle 2 are opened at an angle, and at the same time, the ends of the first opening and closing connecting piece 4 and the second opening and closing connecting piece 5 are also opened at an angle, and the shearing head 6 is separated from the shearing seat 7. The left pressing block 83 and the right pressing block 84 are squeezed, the compression movable spring 822 is compressed, the adjacent single group of limit members 82 moves in two directions, the through holes of the three groups of fixing members 821 are completely overlapped, and the passage of the through hole is the largest. At this time, the branch as the scion is inserted from the outside of the shell 81. After determining the shearing position, the left pressing block 83 and the right pressing block 84 are released. Under the action of the compression movable spring 822, the adjacent single group of limit members 82 moves in two directions, the through holes of the three groups of fixing members 821 are not completely overlapped, and the passage of the through hole is reduced. The spike 824 is attached to the surface of the branch to clamp and fix the branch. The two sets of outer fixings 821 and the middle set of fixings 821 are arranged in different directions, so that during the clamping process, the branches are more stable and not easy to deviate, and are vertical to the channel, ensuring the uniformity of the shearing slope each time. Squeeze the upper handle 1 and the lower handle 2 hard, the shearing head 6 and the shearing seat 7 are close together, and the angled blade 61 cuts the fixed branch bevel. The beveled branch is used as a scion for the next grafting operation. Using this device to cut scions is safer than manually cutting with a blade, and the branches are firmly fixed and not easy to deviate, and the qualified rate of the processed scion section is high.

[0031] The bent first opening and closing connector 4 and the second opening and closing connector 5 ensure that the length of the scion inserted from the scion fixing mechanism 8 and passing through between the first opening and closing connector 4 and the second opening and closing connector 5 is not limited by the handle during operation, and the scion can be cut at any position.

[0032] When the use is finished, the ends of the upper handle 1 and the lower handle 2 are closed, and the blade 61 of the shearing head 6 is inserted into the blade groove 71 to prevent the blade from being scratched and to protect the integrity of the blade.

[0033] The branch to be cut enters the positioning ring 72 of the U-shaped shear seat 7 and passes through the two oblique through holes and out of the positioning ring 72 on the other side. At this time, the branch is at a vertical angle to the blade 61. The upper handle 1 and the lower handle 2 are squeezed hard, and the branch can be cut in a plane, realizing the multifunctional use of the device, which is suitable for different usage situations.

[0034] The above are only the embodiments of the present utility model, and common knowledge such as the specific structures and characteristics known in the solutions is not described in detail herein. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be construed as limiting the claimed rights.
