Based on the embodiments in 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.

[0024] Reference Figure 1-Figure 2The utility model provides an embodiment of a shearing mechanism for a picking robot, comprising a containing shell 1, a fixing ring 2 is fixedly connected to the left side of the outside of the containing shell 1, a connecting frame 3 is fixedly connected to the rear side of the fixing ring 2, so that the fixing ring 2 can provide support for the connecting frame 3, the rear side of the connecting frame 3 is rotatably connected to a power assembly, so that the connecting frame 3 can limit the power assembly, and the right side of the power assembly is rotatably connected to a pulling frame 5, the power assembly comprises a handle 4, the front side of the handle 4 is rotatably connected to the rear side of the connecting frame 3, so that the connecting frame 3 can limit the handle 4, and the right side of the handle 4 is rotatably connected to the left side of the pulling frame 5, and then pulling the handle 4 can make the handle 4 drive the pulling frame 5 to move, the right side of the pulling frame 5 is fixedly connected to a cable 6, and then the pulling frame 5 will drive the cable 6 to move when it moves, and the other side of the cable 6 is fixedly connected to a cutting knife 8, so that the cable 6 will drive the cutting knife 8 to move when it moves.

[0025] To enable it to pick fruits, a spring 7 is sleeved on the outside of the cable 6, a sliding rod 9 is slidably connected to the right side of the accommodating shell 1, and a sleeve tube 10 is fixedly connected to the right side of the sliding rod 9, so that the sliding rod 9 can provide support for the sleeve tube 10, and a baffle 12 is fixedly connected to the rear side of the sleeve tube 10, and a fixed shaft 11 is fixedly connected to the bottom of the rear left end of the baffle 12, so that the baffle 12 can provide support for the fixed shaft 11, and a fixed plate 13 is fixedly connected to the bottom of the rear right end of the baffle 12, so that the baffle 12 can provide support for the fixed plate 13, one end of the spring 7 is fixedly connected to the right side of the cutting knife 8, and the other end of the spring 7 is fixedly connected to the left side of the fixed plate 13, so that the cutting knife 8 will compress the spring 7 when it moves, and a protective cover 14 is fixedly connected to the rear side of the fixing ring 1 2, and the outside of the protective cover 14 is fixedly connected to the rear inside of the fixing ring 2 15, so that the fixing ring 2 15 can provide support for the protective cover 14.

[0026] One side of the cable 6 passes through the middle of the fixing plate 13 and extends outward, so that the fixing plate 13 can provide support for the cable 6. The outside of the cable 6 is slidably connected to the inside of the protective cover 14, so that the protective cover 14 can protect the cable 6. The middle part of the cutting knife 8 is rotatably connected to the outside of the fixed shaft 11, so that the fixed shaft 11 can make the cutting knife 8 rotate more stably. The right side of the outside of the containing shell 1 is fixedly connected with a fixing ring 2 15, so that the containing shell 1 can provide support for the fixing ring 2 15.

[0027] like Figure 1 and Figure 3As shown: a cavity 16 is opened inside the accommodating shell 1, and the interior of the cavity 16 is slidably connected to a limit plate 19, so that the cavity 16 can make the limit plate 19 slide more stably, and the right side of the limit plate 19 is fixedly connected to the left bottom of the sliding rod 9, and then the movement of the sliding rod 9 will drive the limit plate 19 to move, and a threaded groove 20 is opened inside the sliding rod 9, and the external thread of the threaded rod 17 is connected to the inside of the threaded groove 20.

[0028] Therefore, when the threaded rod 17 rotates, the sliding rod 9 will be extended or retracted through the threaded groove 20. The left top end of the threaded rod 17 passes through the left inner wall of the cavity 16 and extends outward. The interior of the accommodating shell 1 is rotatably connected with the threaded rod 17, and the left top end of the threaded rod 17 is fixedly connected with the handle 2 18, so that rotating the handle 2 18 can make the handle 2 18 drive the threaded rod 17 to rotate.

[0030] Working principle: first, when the length of the device needs to be adjusted, the handle 18 can be turned to make the handle 18 drive the threaded rod 17 to rotate, and then the threaded rod 17 will slide in the cavity 16 with the cooperation of the thread groove 20 when rotating, so that the sliding rod 9 can slide out or retract from the cavity 16, and then the length of the device can be adjusted, and then the limit plate 19 can prevent the sliding rod 9 from sliding out too much and sliding out of the cavity 16, so as to improve the durability of the device, and then the sleeve tube 10 is placed at the bottom of the fruit to be picked, and then the handle 1 4 is pulled to make the handle 1 4 drive the pulling frame 5 to move, and then the pulling frame 5 will move when moving. The cable 6 is driven to move, and then the cable 6 can slide inside the protective cover 14, so that the protective cover 14 can protect the cable 6, and at this time the cable 6 will pull the cutting knife 8, so that the cutting knife 8 rotates outside the fixed shaft 11, so that the cutting knife 8 can pick the fruit, and at this time the cutting knife 8 will compress the spring 7. When the fruit picking is completed, the handle 4 is released, which will cause the cable 6 to drive the cutting knife 8 to reset under the resetting force, and then the cutting knife 8 can drive the cable 6 to reset, and then the cable 6 can drive the handle 4 to reset through the pulling frame 5, so that the device can be quickly put into next use, thereby improving the working efficiency of the device.
