DETAILED DESCRIPTION

[0020] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, and are intended to explain the utility model, and cannot be understood as a limitation of the utility model. In the description of the utility model, it is understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "upper surface" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as a limitation of the utility model.

[0021] Please refer to Figure 1-6 The utility model provides an embodiment: a kind of ring cutting equipment for apple tree branch, including hand-held part 1, the middle part of the hand-held part 1 is equipped with the collar 14 for being sleeved in the outside of branch, and one side of the hand-held part 1 is equipped with first connecting part 15, and second connecting part 16 is equipped in the other side of the hand-held part 1, and the inside of the first connecting part 15 and the second connecting part 16 is equipped with connecting hole 13;The first connecting part 15 is connected with the longitudinal cutting tool 2, and the second connecting part 16 is connected with the ring cutting tool 3;The ring cutting tool 3 includes driving rod 30 and tool head assembly 34 linked with the driving rod 30, and rotates in the connecting hole 13 by the driving rod 30, to make the blade 37 equipped on the tool head assembly 34 abutting on the radial direction of branch, then by rotating the hand-held part 1, to make the blade 37 rotate in the radial direction of branch, to complete the ring cutting of branch.

[0022] In summary, the handheld part 1 is sleeved outside the branch, and then the driving rod 30 is rotated to drive the blade 37 to approach and abut against the outside of the branch. At this time, the handheld part 1 is rotated to realize the girdling of the device to the branch. During the girdling, the cutting depth of the device can be further increased by continuously rotating the driving rod 30. Therefore, compared with the prior art, the device is not only convenient to use, but also has fewer parts and lighter weight, so it can be used for a long time.

[0023] Further, since the handheld part 1 has the girdling cutter 3 on one side and the longitudinal cutting cutter 2 on the other side, after the girdling is completed, the girdling blade 37 is retracted, and then the longitudinal cutting blade 37 is pushed out to move upward or downward along the branch to cut the outer skin of the branch. Based on this, the device can realize girdling and longitudinal cutting, so as to meet the use requirements of the user.

[0024] In addition, the tool head assembly 34 further comprises a fixing frame 35 for fixing the blade 37, and the connecting rod 33 passes through the driving rod 30 and is connected with the screw hole 39 arranged on the fixing frame 35, so that the driving rod 30 rotates outside the connecting rod 33. Therefore, when the driving rod 30 rotates inside the connecting hole 13, the fixing frame 35 cannot be rotated, so that the fixing frame 35 can only move in a certain direction to ensure that the blade 37 can only move or rotate in the same direction during cutting. In particular, the connecting rod 33 passes through the driving rod 30 and is connected with the screw hole 39, which not only realizes the reliable linkage between the driving rod 30 and the fixing frame 35, but also makes the assembly and disassembly of the driving rod 30 and the fixing frame 35 simple and convenient.

[0025] Further, in order to facilitate the installation and replacement of the blade 37, the fixing frame 35 is provided with a threaded hole 36 at one end away from the connecting rod 33, and the screw rod 38 passes through the blade 37 and is connected with the threaded hole 36 to assemble the blade 37 to the fixing frame 35.

[0026] In order to improve the reliability of the movement of the driving rod 30, the connecting hole 13 comprises an internal threaded hole 11 threadedly matched with the driving rod 30, and the inner wall surface of the internal threaded hole 11 is provided with a horizontal groove 10 and a vertical groove 12. Since the driving rod 30 is threadedly matched with the internal threaded hole 11, after the driving rod 30 drives the blade 37 to move towards the branch, the blade 37 will not automatically retreat, thereby ensuring that the cutting depth of the blade 37 is controllable and reliable.

[0027] Further, since the longitudinal cutting tool 2 and the ring cutting tool 3 are consistent in structure, and the outer circumferential surface of the fixing frame 35 is connected with the horizontal slot 10 or the vertical slot 12 through the protruding part 310. Therefore, when the protruding part 310 is connected with the vertical slot 12, the device can realize ring cutting; when the protruding part 310 is connected with the horizontal slot 10, the device can realize longitudinal cutting; in addition, the longitudinal cutting tool 2 and the ring cutting tool 3 are consistent in structure, which can make the two tools be used mutually, so as to reduce the production cost of the device; in addition, the protruding part 310 can prevent the fixing frame 35 from rotating axially after being matched with the horizontal slot 10 or the vertical slot 12, so as to avoid the deformation of the blade 37 due to the torsion.

[0028] In addition, since the driving part 31 is arranged on the surface of the driving rod 30 which faces the connecting rod 33, the driving rod 30 can be rotated more easily through the driving part 31; in addition, the accommodating slot 32 is arranged in the driving part 31 to accommodate the end of the connecting rod 33, so that the end of the connecting rod 33 can be hidden in the accommodating slot 32, so as to reduce the overall length of the device, and make the device rotate more smoothly between branches.

[0029] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
