Detailed Embodiments

[0018] The following will further elaborate on the present application with reference to the Figures 1-3 drawings.

[0019] The embodiment of the present application discloses a shearing device for grape picking. Refer to Figure 1 , Figure 2 and Figure 3, A shearing device for grape picking. On one side of the outer walls of the first scissor blade 1 and the second scissor blade 2, connecting rods 4 are fixedly connected. On one side of the interior of each connecting rod 4, an adjustment groove 11 is provided. Inside each connecting rod 4, adjusting rods 5 are slidably connected through the adjustment grooves 11. On the opposite sides of the two adjusting rods 5, upper connecting plates 7 are fixedly connected. On the opposite sides of the two connecting rods 4, lower connecting plates 12 are fixedly connected. On the outer walls of the adjusting rods 5, second threaded rods 16 are fixedly connected through the upper connecting plates 7. On the outer walls of the connecting rods 4, first threaded rods 14 are fixedly connected through the lower connecting plates 12. On the outer walls of the connecting rods 4, rotating rods 8 are rotatably connected through the second threaded rods 16 and the first threaded rods 14. On one side of the interior of each rotating rod 8 corresponding to the second threaded rod 16, a second thread groove 15 is provided. On the interior of each rotating rod 8 corresponding to the first threaded rod 14, a first thread groove 13 is provided;

[0020] By adopting the above technical solution, the two ends of the rotating rod 8 are respectively connected to the first threaded rod 14 and the second threaded rod 16. And in the interior of the rotating rod 8, a first thread groove 13 and a second thread groove 15 are respectively provided corresponding to the first threaded rod 14 and the second threaded rod 16. At the same time, the threads on the inner walls of the first thread groove 13 and the second thread groove 15 are respectively set to have threads opposite to the threads on the outer walls of the first threaded rod 14 and the second threaded rod 16. At the same time, the second threaded rod 16 and the adjusting rod 5 are connected through the upper connecting plate 7, and the first threaded rod 14 and the connecting rod 4 are connected through the lower connecting plate 12. Subsequently, by rotating the rotating rod 8 forward, the first threaded rod 14 and the second threaded rod 16 are moved out from both sides inside the rotating rod 8, so as to drive the adjusting rod 5 to displace along the inner wall of the adjustment groove 11. Thus, by rotating the rotating rod 8, the length of the adjusting rod 5 moving out from the interior of the adjustment groove 11 is adjusted, and the overall length of the device is adjusted. Similarly, by rotating the rotating rod 8 in reverse, the adjusting rod 5 is driven to move into the adjustment groove 11, shortening the length of the device, achieving the effect of facilitating the adjustment of the length of the device.

[0021] Refer to Figure 1 , Figure 2 and Figure 3 , On the opposite sides of the two connecting rods 4, fixing plates 9 are fixedly connected. On the outer walls of the connecting rods 4, tension springs 10 are fixedly connected through the two fixing plates 9. The first scissor blade 1 and the second scissor blade 2 are rotatably connected through a bolt shaft 3. On one side of each adjusting rod 5, an anti-slip grip 6 is fixedly connected;

[0022] By adopting the above technical solution, the first scissor blade 1 and the second scissor blade 2 are connected by the bolt shaft 3. The first scissor blade 1 and the second scissor blade 2 are respectively connected to the connecting rod 4. The adjusting rod 5 is connected to the anti-slip grip 6. The staff can pull the two anti-slip grips 6 with both hands to drive the first scissor blade 1 and the second scissor blade 2 to rotate, so as to drive the first scissor blade 1 and the second scissor blade 2 to move away from each other. The two fixing plates 9 are connected to the tension spring 10, and the two fixing plates 9 are respectively installed on the outer wall of the connecting rod 4. When the two connecting rods 4 rotate, the tension spring 10 is stretched. The elastic potential generated by the stretching of the tension spring 10 drives the first scissor blade 1 and the second scissor blade 2 to fit together to cut the grapes, which can help the workers cut the grape stalks, achieving the effect of facilitating the workers to cut and pick the grapes.

[0023] The implementation principle of a grape picking shearing device according to an embodiment of the present application is as follows: both ends of the rotating rod 8 are respectively connected to the first threaded rod 14 and the second threaded rod 16. The first threaded groove 13 and the second threaded groove 15 are respectively opened in the rotating rod 8 corresponding to the first threaded rod 14 and the second threaded rod 16. At the same time, threads opposite to the outer wall threads of the first threaded rod 14 and the second threaded rod 16 are respectively arranged on the inner walls of the first threaded groove 13 and the second threaded groove 15. At the same time, the second threaded rod 16 and the adjusting rod 5 are connected by the upper connecting plate 7, and the first threaded rod 14 and the connecting rod 4 are connected by the lower connecting plate 12. Then, by rotating the rotating rod 8 forward, the first threaded rod 14 and the second threaded rod 16 are moved out from both sides inside the rotating rod 8, so as to drive the adjusting rod 5 to displace along the inner wall of the adjusting groove 11. Thus, by rotating the rotating rod 8, the length of the adjusting rod 5 moving out from the inside of the adjusting groove 11 is adjusted, and the overall length of the device is adjusted. Similarly, by rotating the rotating rod 8 in reverse, the adjusting rod 5 is driven to move into the adjusting groove 11, shortening the length of the device, facilitating the adjustment of the length of the grip area of the device, and facilitating the shearing of grapes at high places. The first scissor blade 1 and the second scissor blade 2 are connected by the bolt shaft 3. The first scissor blade 1 and the second scissor blade 2 are respectively connected to the connecting rod 4. The adjusting rod 5 is connected to the anti-slip grip 6. The staff can pull the two anti-slip grips 6 with both hands to drive the first scissor blade 1 and the second scissor blade 2 to rotate, so as to drive the first scissor blade 1 and the second scissor blade 2 to move away from each other. The two fixing plates 9 are connected to the tension spring 10, and the two fixing plates 9 are respectively installed on the outer wall of the connecting rod 4. When the two connecting rods 4 rotate, the tension spring 10 is stretched. The elastic potential generated by the stretching of the tension spring 10 drives the first scissor blade 1 and the second scissor blade 2 to fit together to cut the grapes, which can help the workers cut the grape stalks.
