[0024] The cutting part 2 includes a fixed blade 21 and a movable blade 22. The fixed blade 21 and the movable blade 22 simultaneously ring cut the branches. An adjustment device 23 is provided between the fixed blade 21 and the movable blade 22. The adjustment device 23 drives the movable blade 22 to move relative to the fixed blade 21 to adjust the ring cutting or ring stripping width.

[0025] The blade heads of the fixed blade 21 and the movable blade 22 are U-shaped blade heads or straight-line blade heads to adapt to plant branches of different shapes and sizes.

[0026] like Figure 3 As shown, the adjusting device 23 includes a rotating shaft 231, and the annular wall surface of the rotating shaft 231 is provided with a first external thread 232. The rotating shaft 231 is rotatably connected to the fixed blade 21, and the first external thread 232 is threadedly connected to the movable blade 22. The distance between the fixed blade 21 and the movable blade 22 can be adjusted by manually turning the rotating shaft 231.

[0027] Specifically, the fixed blade 21 and the movable blade 22 both include a blade head and a base. A rectangular groove is provided on the base of the fixed blade 21. A connecting pin is provided in the rectangular groove. Both ends of the connecting pin are fixedly connected to the base of the fixed blade 21. A rotating shaft 231 is sleeved on the connecting pin. Preferably, the length of the rotating shaft 231 is equal to the length of the rectangular groove to avoid axial displacement of the rotating shaft 231 during rotation (in order to clearly show the connection method between the rotating shaft 231 and the fixed blade 21, Figure 3 The length of the rotating shaft 231 is less than the length of the rectangular groove). The annular wall surface of the rotating shaft 231 is provided with a first external thread 232, and the base of the movable blade 22 is provided with a threaded hole 221, and the threaded hole 221 matches the first external thread 232. When the first external thread 232 is manually moved, the first external thread 232 drives the base of the movable blade 22 to move laterally, so that the movable blade 22 can move relative to the fixed blade 21.

[0028] like Figure 5As shown, the base of the movable blade 22 is in the shape of an elongated strip, and strip-shaped protrusions are provided on both sides of the base, and the strip-shaped protrusions limit the movable blade 22 to be displaced only along the direction of the first external thread 232. A card slot matching the base of the movable blade 22 is provided on the base of the fixed blade 21, and the card slot is connected to the rectangular slot on the base of the fixed blade 21, so that when the rotating shaft 231 in the rectangular slot is rotated, the base of the movable blade 22 can move in the base of the fixed blade 21.

[0029] As an implementable embodiment, a cutting part 2 is provided at the front end of one handle 1, and a guide part 3 is provided at the front end of the other handle 1. The guide part 3 is arc-shaped and its concave surface faces the cutting part 2. The arc-shaped surface of the guide part 3 is used to clamp the branches to be ring-cut.

[0030] In order to facilitate the removal of the phloem after ring cutting, a pointed shovel 31 is provided at the end of the guide part 3 away from the joint pin 11. Specifically, the shovel surface of the pointed shovel 31 is flat, and the front end edge of the pointed shovel 31 is provided with a sharp shovel edge for cutting into the phloem and removing the phloem.

[0031] In order to facilitate gripping, a gripping portion 12 is provided at the rear end of the two handles 1. The gripping portion 12 is made of plastic material and is used to increase the friction between the hand and the handle 1. The gripping portion 12 is arc-shaped, and the gripping portions 12 on the two handles 1 correspond to each other with concave surfaces.

[0032] In order to accurately set the girdling width, a scale is provided on one side of the adjusting device 23 to indicate the distance of the movable blade 22 relative to the fixed blade 21 .

[0033] The working principle of this utility model:

[0034] According to the required ring-barking width, the adjusting device 23 is manually turned to rotate the first external thread 232, thereby driving the movable blade 22 to move along the thread direction. When the distance between the two blades is consistent with the required ring-barking width, the branch is stuck in the arc edge of the guide part 3, and the holding part 12 at the rear end of the handle 1 is gripped to apply pressure so that the fixed blade 21 and the movable blade 22 are close to the branch. The handle 1 is rotated with force, and the fixed blade 21 and the movable blade 22 go around the branch to obtain two ring-cutting edges. The bark between the two edges is shoveled away using the pointed shovel 31 provided at the end of the guide part 3 to complete the ring-barking.
