DETAILED DESCRIPTION

[0020] The specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] A branch grafting device, such as Figure 1-2 As shown, it includes a sleeve 1 with an opening at the bottom and a sealed top; corresponding positions of two opposite side walls of the sleeve 1 are provided with "V"-shaped limiting grooves 2; two movable cutters 8 are slidably installed in the limiting grooves 2; both ends of the movable cutter 8 extend beyond the side walls of the sleeve 1.

[0022] When in use, the lower end of the sleeve 1 is downwardly covered over the stock to be cut, and the upper end surface of the stock moves upward relative to the limiting groove 2, gradually lifting the two movable cutters 8. When the sleeve 1 is lowered to a certain position, one of the movable cutters 8 is held and pushed to slide along the limiting groove 2 to cut the stock, and then the other movable cutter 8 is moved in the same manner to complete the cutting on the other side, thereby cutting a V-shaped groove in the same shape as the limiting groove 2 at the upper end of the stock.

[0023] Specifically, in order to save effort when pushing the movable cutter 8, a fixed cutter 3 is fixedly connected to the radial middle position between the inner walls of the sleeve 1; the fixed cutter 3 is located directly below the limiting groove 2. When the sleeve 1 covers the stock and descends, the fixed cutter 3 cuts a slit along the center of the stock, making it easier to cut the V-shaped cut later.

[0024] Specifically, the top of the sleeve 1 is threadedly connected to the first screw 6; the upper end of the first screw 6 is fixedly connected to the first rotating part 7, and the lower end is fixedly connected to the limit plate 4. The limit plate 4 is used to limit the depth of the stock inserted into the sleeve, so that the depth of the V-shaped groove finally cut out of the upper end of the stock is consistent. By rotating the first rotating part 7, the depth of the limit plate 4 extending into the sleeve 1 can be adjusted, which is convenient for technicians to flexibly adjust according to the actual situation such as the type of stock.

[0025] Specifically, a first boss 5 is fixed to the top of the sleeve 1; a first screw 6 passes through the first boss 5, and the two are threadedly connected. Since the wall thickness of the sleeve 1 is relatively small, the connection between the first screw 6 and the sleeve 1 may be unstable, and the added first boss 5 serves to extend the thread operation area.

[0026] Specifically, in order to facilitate holding the movable blade 8 , blade handles 10 are installed at both ends of the movable cutter 8 .

[0027] Specifically, handles 9 are fixedly connected to both sides of the outer wall of the sleeve 1. When the sleeve 1 is moved downward, since the fixed cutter 3 needs to cut the stock, the sleeve 1 can be conveniently held by holding the handles 9.

[0028] Specifically, in order to prevent the sleeve 1 from moving when cutting the V-shaped groove, a plurality of clamping components are installed on the side wall of the sleeve 1.

[0029] Specifically, the clamping assembly includes a second screw 12 threadedly connected to the side wall of the sleeve 1; one end of the second screw 12 is fixedly connected to a second rotating portion 13, and the other end is fixedly connected to a clamping plate 11. By rotating the second rotating portion 13, the clamping plate 11 can be driven to gradually approach the rootstock until the clamping plate 11 tightly clamps the rootstock.

[0030] Specifically, the side wall of the sleeve 1 is also fixedly connected with a plurality of second bosses 14; the second screw 12 passes through the second bosses 14, and the two are threadedly connected. The second bosses 14 also play the role of extending the thread operation area.

[0031] Specifically, in order to prevent the rootstock from being scratched, a protective layer 15 is provided on the inner side of the limiting plate 4 and the clamping plate 11 .

[0032] Specifically, in order to prevent slipping, anti-slip grooves are provided on the first rotating part 7 and the second rotating part 13 .

[0033] The working principle of this utility model:

[0034] Before working, according to the predetermined depth of the V-shaped groove, the first rotating part 7 is rotated to adjust the depth of the limit plate 4 extending into the sleeve 1. During operation, the lower end of the sleeve 1 is downwardly covered to cover the stock to be cut, and as the sleeve 1 gradually moves downward, the fixed cutter 3 cuts a slit along the center position of the stock, making it easier to cut the V-shaped cut later. The upper end surface of the stock moves upward relative to the limit groove 2, gradually lifting the two movable cutters 8. When the sleeve 1 drops to a certain position, the top of the stock supports the limit plate 4. Then the second rotating part 13 is rotated to drive the clamping plate 11 to gradually approach the stock until the clamping plate 11 tightly clamps the stock. Then hold one of the movable cutters 8 and push the movable cutter 8 to slide along the limit groove 2 to cut the stock, and then move the other movable cutter 8 in the same operation to complete the cutting on the other side, thereby cutting a V-shaped groove with the same shape as the limit groove 2 at the upper end of the stock. The utility model has a simple structure. Due to the limitation of the limiting groove 2, the movable cutter 8 will not deviate during the movement process, the incision quality is good, the cutting efficiency is high, and it is not easy to scratch the hand.
