Description

Technical Field

[0001] The invention relates to the technical field of cultivating young branch grafted seedlings, and in particular to a process for cultivating young branch grafted seedlings of macadamia nuts. Background Art

[0002] When grafting fruit trees, special grafting shears are needed to prune branches. At present, grafting shears are generally manually operated. When using them, operators need to hold the grafting shears and move them to the branches that need to be grafted, and then let the blades of the grafting shears cut the branches vertically. During the pruning process, it is necessary to ensure that the grafting shears and the branches are perpendicular to each other, otherwise the pruned branches cannot be accurately aligned and grafted together, affecting the normal growth of the plants in the later stage. However, the existing grafting shears do not have the function of assisting operators to vertically align plants, which increases the difficulty of plant grafting operations and reduces the probability of successful plant grafting. Therefore, in order to improve the efficiency and success rate of plant grafting by operators, the present invention provides a process for cultivating young branches and grafting seedlings of macadamia nuts to meet the needs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a process for cultivating young branches and grafted seedlings of macadamia nuts. By setting a driving unit, electric drive is used instead of manual pressure to prune branches, thereby effectively improving the efficiency of operators in pruning branches and the success rate of branch pruning; by setting a pruning component, not only can the operator be assisted to align the grafting shears vertically with the branches, but the branches can also be clamped and fixed during the pruning process, thereby preventing the branches from being misplaced during the pruning process and improving the success rate of branch pruning. The above settings can solve the problems of low efficiency and low success rate in pruning branches during the use of grafting shears at this stage.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A process for cultivating young branches and grafted seedlings of macadamia nuts comprises the following steps:

[0006] Step 1: Spike preparation: Spikes should be collected from scion nurseries certified at the provincial level or above, or from orchards with clear varieties, high purity, and no quarantine pests. Select one to three-year-old branches that are thick, full of tissue, full of buds, fresh and clean as scion strips. Spike strips should be grafted as soon as they are picked. After the scion strips are cut, the leaves are immediately trimmed with branch shears, and the petioles are retained. They are placed in a cool place for temporary storage and moisture retention. If the scion strips are not used up on the same day or the scion strips are not in the same place as the rootstock, they should be wrapped with sterilized towels, blankets, sacks, etc. to keep them moisturized and stored in a cool place for a short period of time;

[0007] Step 2: High grafting position: It depends on the age of the rootstock and the size of the crown. For young trees or small crowns, the high grafting position should be low, and the height of the high grafting should be selected at a height of 0.8m to 2m from the ground. For rootstocks under 10 years old, it is appropriate to high graft on the main branch, secondary main branch or main trunk. For rootstocks between 10 and 20 years old, it is appropriate to high graft on secondary main branches, main branches and side branches.

[0008] Step 3: Number of grafted branches: Determine the number of grafted branches based on the age of the tree and the transformation of the tree shape. For trees ≤10 years old, graft 5 to 10 branches; for trees >10 years old, graft 10 to 20 branches.

[0009] Step 4: High-grafting replacement method: For trees with age ≤ 10 years and cut diameter ≤ 5 cm, use grafting shears to prune branches and then use joint grafting, cleft grafting or cut grafting. For trees with age > 10 years and cut diameter > 5 cm, use grafting shears to prune branches and then use cleft grafting or cut grafting. For sprouting branches with a base stem thickness greater than 0.7 cm growing near the large cut, use grafting shears to prune branches and then use joint grafting. The high-grafted scions should be exposed to 2 cm of white after using the cleft grafting or cut grafting methods. After high grafting, the grafting sites with larger wounds should be coated with sealing agents. The trunk, main branches and secondary main branches should be painted white or wrapped with straw mats or straw ropes for sun protection and moisture retention.

[0010] Step 5. Management after high grafting: Re-grafting: Check 30-40 days after grafting. If the scion is found to be dead, re-graft it in time. Unbinding: If the cut is small, unbind it when the first round of newly grown scion shoots is stable. If the cut is large, unbind it when the wound is basically healed and the scion has not formed a ring.

[0011] Step 6, remove sprouts and prune auxiliary branches: When the rootstock near the surviving scion has stable sprouts, remove the sprouts until there are no more sprouts. Leave a small amount of sprouts at the missing branches in the inner chamber or where the scion has not survived, so as to prepare for grafting the next year. When the sunlight in the orchard is too strong and it is easy to cause sunburn, leave a few sprouts to shade. When the growth of the high-grafted surviving branches is affected by the auxiliary branches, gradually prune the auxiliary branches to eventually form a crown composed of high-grafted varieties.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] In the above scheme, by setting a driving unit, electric drive is used instead of manual pressure to prune the branches, thereby effectively improving the efficiency of the operator in pruning the branches, and the electric drive operation is more convenient for the operator to manually hold the grafting shears, further ensuring the stability of the grafting shears during branch pruning and improving the success rate of branch pruning; by setting a pruning component, not only can the operator be assisted to align the grafting shears vertically with the branches, but the branches can be clamped and fixed during the pruning process, thereby preventing the branches from being misplaced during the pruning process and improving the success rate of branch pruning. In addition, for different types of branches, the operator can manually change the blade shape of the grafting shears without disassembling the grafting shears to replace the blade. Such a setting greatly improves the scope of application and convenience of use of the grafting shears.

[0024] By setting the U-shaped blade and the V-shaped blade, the operator can selectively slide the adjustment rod according to the type and size of the branch, and insert the adjustment rod into any one of the second arc groove and the third arc groove. When the rotating plate rotates, the adjustment rod will drive the corresponding blade to move toward the U-shaped groove and prune the branch. Since the shapes of the U-shaped blade and the V-shaped blade are different, the contours left by pruning are also different, so it is suitable for branches of different types and sizes. There is no need for the operator to carry multiple grafting shears of different specifications, and there is no need for the operator to temporarily disassemble the grafting shears to replace the blades, thereby improving the efficiency of branch pruning and grafting.

[0025] By setting the movable clamping plate, when the operator inserts the adjusting rod into the first arc-shaped groove, the adjusting rod will drive the slide plate to move toward the U-shaped groove during the rotation of the rotating plate. At this time, the movable clamping plate will cooperate with the fixed clamping plate to clamp and fix the branch, thereby achieving the positioning effect of the branch, ensuring that the grafting shears and the branch are perpendicular to each other, and improving the success rate of branch pruning. During the process of clamping the branch by the movable clamping plate, the operator can change the position of the adjusting rod and select different blades to prune the branch. Moreover, the blade will not cause any impact on the movable clamping plate during cutting the branch, thereby further improving the efficiency of branch pruning. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a process for cultivating young branches and grafted seedlings of macadamia nuts, comprising the following steps:

[0056] Step 1: Spike preparation: Spikes should be collected from scion nurseries certified at the provincial level or above, or from orchards with clear varieties, high purity, and no quarantine pests. Select one to three-year-old branches that are thick, full of tissue, full of buds, fresh and clean as scion strips. Spike strips should be grafted as soon as they are picked. After the scion strips are cut, the leaves are immediately trimmed with branch shears, and the petioles are retained. They are placed in a cool place for temporary storage and moisture retention. If the scion strips are not used up on the same day or the scion strips are not in the same place as the rootstock, they should be wrapped with sterilized towels, blankets, sacks, etc. to keep them moisturized and stored in a cool place for a short period of time;

[0057] Step 2: High grafting position: It depends on the age of the rootstock and the size of the crown. For young trees or small crowns, the high grafting position should be low, and the height of the high grafting should be selected at a height of 0.8m to 2m from the ground. For rootstocks under 10 years old, it is appropriate to high graft on the main branch, secondary main branch or main trunk. For rootstocks between 10 and 20 years old, it is appropriate to high graft on secondary main branches, main branches and side branches.

[0058] Step 3: Number of grafted branches: Determine the number of grafted branches based on the age of the tree and the transformation of the tree shape. For trees ≤10 years old, graft 5 to 10 branches; for trees >10 years old, graft 10 to 20 branches.

[0059] Step 4: High-grafting replacement method: For trees with age ≤ 10 years and cut diameter ≤ 5 cm, use grafting shears to prune branches and then use joint grafting, cleft grafting or cut grafting. For trees with age > 10 years and cut diameter > 5 cm, use grafting shears to prune branches and then use cleft grafting or cut grafting. For sprouting branches with a base stem thickness greater than 0.7 cm growing near the large cut, use grafting shears to prune branches and then use joint grafting. The high-grafted scions should be exposed to 2 cm of white after using the cleft grafting or cut grafting methods. After high grafting, the grafting sites with larger wounds should be coated with sealing agents. The trunk, main branches and secondary main branches should be painted white or wrapped with straw mats or straw ropes for sun protection and moisture retention.

[0060] Step 5. Management after high grafting: Re-grafting: Check 30-40 days after grafting. If the scion is found to be dead, re-graft it in time. Unbinding: If the cut is small, unbind it when the first round of newly grown scion shoots is stable. If the cut is large, unbind it when the wound is basically healed and the scion has not formed a ring.

[0061] Step 6, remove sprouts and prune auxiliary branches: When the rootstock near the surviving scion has stable sprouts, remove the sprouts until there are no more sprouts. Leave a small amount of sprouts at the missing branches in the inner chamber or where the scion has not survived, so as to prepare for grafting the next year. When the sunlight in the orchard is too strong and it is easy to cause sunburn, leave a few sprouts to shade. When the growth of the high-grafted surviving branches is affected by the auxiliary branches, gradually prune the auxiliary branches to eventually form a crown composed of high-grafted varieties.

[0062] The invention also includes grafting shears, which include a main handle 1, a battery 101 is fixedly connected to the bottom of the main handle 1, a shell 102 is fixedly connected to the top of the main handle 1, a sheet metal 2 is fixedly connected to the outer wall of the shell 102, and a rotating plate 3 is rotatably connected to the sheet metal 2; a driving unit, which is used to drive the rotating plate 3 to rotate on the sheet metal 2, and the driving unit is connected to the main handle 1; a pruning unit, which is used to prune branches, and the pruning unit is respectively connected to the sheet metal 2 and the rotating plate 3. The grafting shears provided by the present application are provided with a driving unit, and use electric drive instead of manual pressure to prune branches, thereby effectively improving the operator's pruning of branches. The electric drive operation makes it more convenient for the operator to manually hold the grafting shears, which further ensures the stability of the grafting shears during branch pruning and improves the success rate of branch pruning. By setting the pruning component, it can not only assist the operator to align the grafting shears vertically with the branches, but also clamp and fix the branches during the pruning process, thereby preventing the branches from being misplaced during the pruning process and improving the success rate of branch pruning. In addition, for different types of branches, the operator can manually change the blade shape of the grafting shears without disassembling the grafting shears to replace the blade. Such a setting greatly improves the scope of application and convenience of use of the grafting shears.

[0063] As an implementation method in this embodiment, Figures 1 to 5As shown, the driving unit includes a motor 103 fixedly connected to the inner wall of the main body handle 1, the power supply end of the motor 103 is connected to the battery 101, the output end of the motor 103 is fixedly connected to the screw rod 104, the top outer wall of the screw rod 104 is screwed with a lifting seat 105, the top of the lifting seat 105 is rotatably connected to a touch paddle 107 and a connecting rod 108, the touch paddle 107 and the connecting rod 108 are connected to the lifting seat 105 through the same rotating shaft, and the lifting seat 105 is fixedly connected to a micro switch 106 on the side close to the touch paddle 107, and the connecting rod 108 is connected to the lifting seat 105 through the same rotating shaft. The end of 108 away from the lifting seat 105 is rotatably connected to the rotating plate 3. The motor 103 is installed in the main body handle 1 and is powered by the battery 101. When the operator presses the touch paddle 107, the pressure on the touch paddle 107 will be transmitted to the micro switch 106 to turn it on. After the micro switch 106 is turned on, the battery 101 will power the motor 103. After the motor 103 is powered on, it will drive the screw rod 104 to rotate. During the rotation of the screw rod 104, under the action of the thread drive, the lifting seat 105 will move downward on the screw rod 104 toward the position of the motor 103 The lifting seat 105 is rotatably connected to the top thereof with the touch-sensitive paddle 107 and the connecting rod 108, and the touch-sensitive paddle 107 and the connecting rod 108 are connected to the lifting seat 105 through the same rotating shaft. Therefore, the lifting seat 105 will simultaneously drive the touch-sensitive paddle 107 and the connecting rod 108 to move downward during its movement. Since the rotating plate 3 and the sheet metal 2 are rotatably connected together, and the end of the connecting rod 108 away from the lifting seat 105 is rotatably connected to the rotating plate 3, the connecting rod 108 will drive the rotating plate 3 to rotate on the sheet metal 2 during its downward movement. During the rotation process, the pruning assembly will be driven to prune the branches, thereby replacing manual pressure on the grafting shears, reducing the difficulty of operating the grafting shears and improving the stability of the operator holding the grafting shears. When the lifting seat 105 moves to the end of the screw rod 104, the motor 103 will automatically reverse, and the screw rod 104 will drive the lifting seat 105 to reset upward. When the lifting seat 105 is completely reset, the motor 103 stops rotating. When the operator presses the touch paddle 107 again, the motor 103 will repeat the above work, thereby achieving the effect of repeatedly pruning the branches.

[0064] As an implementation method in this embodiment, Figures 4 to 10 and Figures 18 to 20As shown, the pruning unit includes a positioning plate 4 fixedly connected to the sheet metal 2 by screws, the contour of the positioning plate 4 is adapted to the contour of the sheet metal 2, an arc plate 401 is fixedly connected to the positioning plate 4, a fixed clamping plate 5 is fixedly connected to the positioning plate 4, the fixed clamping plate 5 is fixed to the positioning plate 4 and the sheet metal 2 by screws, a U-shaped groove 201 is provided on one side of the sheet metal 2 close to the fixed clamping plate 5, a slide plate 6, a U-shaped blade 7 and a V-shaped blade 8 are slidably connected between the sheet metal 2 and the positioning plate 4, wherein the slide plate 6 is close to the sheet metal 2, the V-shaped blade 8 is close to the positioning plate 4, and the U-shaped blade 7 is located in the middle. When the operator needs to prune branches, the branches are placed It can be placed in the U-shaped groove 201, and a positioning plate 4 made of plastic is installed on the sheet metal 2 by screws. There is a certain gap between the positioning plate 4 and the sheet metal 2, and the slide plate 6, U-shaped blade 7 and V-shaped blade 8 are slidably connected in this gap. It is worth mentioning that the size of the gap between the positioning plate 4 and the sheet metal 2 is larger than the size of the slide plate 6, U-shaped blade 7 and V-shaped blade 8. This arrangement is to avoid the movement trajectory of the slide plate 6, U-shaped blade 7 and V-shaped blade 8, and ensure that the slide plate 6, U-shaped blade 7 and V-shaped blade 8 can smoothly pass through the positioning plate 4 and enter the U-shaped groove 201 under the driving action of the rotating plate 3.

[0065] In this embodiment, if Figures 1 to 12As shown, the sheet metal 2 is provided with a first arc groove 204, a second arc groove 205 and a third arc groove 206 in sequence from top to bottom on one side away from the U-shaped groove 201, and a straight slide groove 207 is provided at one end of the first arc groove 204, the second arc groove 205 and the third arc groove 206 away from the U-shaped groove 201. The positions of the rotating plate 3 and the straight slide groove 207 correspond to each other, and an adjusting rod 303 is slidably connected to the slide plate 6. An adjusting slide groove 301 is provided at one end of the rotating plate 3, and a round slider 302 is slidably connected in the adjusting slide groove 301. The round slider 302 has a hollow profile, and The size of the inner circumference of the circular slider 302 is larger than the size of the adjusting rod 303. The adjusting rod 303 and the slide plate 6 are slidably connected through the circular slider 302. The circular slider 302 and the adjusting rod 303 are fixedly connected through a reset spring 304. The reset spring 304 is a conical structure, wherein the sizes of the two ends of the reset spring 304 are respectively adapted to the size of the outer wall of the adjusting rod 303 and the size of the inner circumference of the circular slider 302. The operator can slide the adjusting rod 303 to change the position of the adjusting rod 303. Since the circular slider 302 and the adjusting rod 303 are fixedly connected through the reset spring 304, When the operator needs to slide the adjusting rod 303, the operator pulls the adjusting rod 303 outward to disengage it from the groove on the sheet metal 2. When the adjusting rod 303 slides to the desired position, the operator stops pulling the adjusting rod 303 outward. Under the tension of the reset spring 304, the adjusting rod 303 will automatically reset and be reinserted into the groove of the sheet metal 2. The above-mentioned structure allows the operator to selectively slide the adjusting rod 303 and insert the adjusting rod 303 into any one of the first arc groove 204, the second arc groove 205 and the third arc groove 206 according to the positions of the first arc groove 204, the second arc groove 205 and the third arc groove 206. In the groove body, since the first arc groove 204, the second arc groove 205 and the third arc groove 206 are all arc-shaped contours, and the centers of the three are the axis of the rotating shaft between the rotating plate 3 and the sheet metal 2, when the rotating plate 3 rotates, the movement trajectory of the adjusting rod 303 is adapted to the contours of the first arc groove 204, the second arc groove 205 and the third arc groove 206. Such an arrangement enables the adjusting rod 303 to have three different movement trajectories when the rotating plate 3 rotates, and these three movement rules are consistent with the positions of the first arc groove 204, the second arc groove 205 and the third arc groove 206.

[0066] In this embodiment, if Figures 11 to 20As shown, the slide plate 6 is provided with a groove body that matches the positions of the first arc groove 204, the second arc groove 205 and the third arc groove 206, and an elastic sheet 602 is fixedly connected to the groove body at the position of the first arc groove 204 on the slide plate 6, and the elastic sheet 602 is a curved elastic structure. The U-shaped blade 7 is provided with a groove body that matches the positions and sizes of the first arc groove 204 and the third arc groove 206, and the U-shaped blade 7 is provided with a hole body that corresponds to the position of the second arc groove 205 and matches the size of the adjusting rod 303, and the V-shaped blade 8 is provided with a groove body that matches the positions and sizes of the first arc groove 204 and the second arc groove 205, and the V-shaped blade 8 is provided with a hole body that corresponds to the position of the third arc groove 206 and matches the size of the adjusting rod 303, a hole body of a size matching that of the positioning plate 4, a partition 402 is fixedly connected to the inner wall of the positioning plate 4, the partition 402 is spaced between the U-shaped blade 7, the V-shaped blade 8 and the slide plate 6, the slide plate 6, the U-shaped blade 7 and the V-shaped blade 8 are stacked in the gap between the sheet metal 2 and the positioning plate 4, and by providing grooves and holes at different positions on the slide plate 6, the U-shaped blade 7 and the V-shaped blade 8, the operator can drive the corresponding plate body to move separately when inserting the adjusting rod 303 into the hole bodies at different positions; specifically, when the operator inserts the adjusting rod 303 into the first arc-shaped groove 204, since the U-shaped blade 7 and the V-shaped blade 8 are provided with grooves that are matched with the position and size of the first arc-shaped groove 204, and the slide plate 6 is located at the first arc-shaped groove An elastic sheet 602 is installed in the groove body at the position of the groove 204, and the elastic sheet 602 can block and limit the adjusting rod 303. Therefore, when the rotating plate 3 rotates, under the blocking and limiting effect of the elastic sheet 602, the adjusting rod 303 will drive the sliding plate 6 to move toward the U-shaped groove 201; when the operator inserts the adjusting rod 303 into the second arc groove 205, since the sliding plate 6 and the V-shaped blade 8 are both provided with groove bodies that are compatible with the position and size of the second arc groove 205, and the U-shaped blade 7 is only provided with a hole body that is compatible with the size of the adjusting rod 303 at the position of the second arc groove 205, the adjusting rod 303 can be inserted into the hole body on the U-shaped blade 7. When the rotating plate 3 rotates, the blocking and limiting effect of the hole body on the U-shaped blade 7 When the operator inserts the adjusting rod 303 into the third arc groove 206, since the slide plate 6 and the U-shaped blade 7 are both provided with groove bodies that are compatible with the position and size of the third arc groove 206, and the V-shaped blade 8 is only provided with a hole body that is compatible with the size of the adjusting rod 303 at the position of the third arc groove 206, the adjusting rod 303 can be inserted into the hole body on the V-shaped blade 8. When the rotating plate 3 rotates, under the blocking and limiting action of the hole body on the V-shaped blade 8, the adjusting rod 303 will drive the V-shaped blade 8 to move toward the U-shaped groove 201 and prune the branches in the U-shaped groove 201.In summary, the operator can selectively slide the adjustment rod 303 according to the type and size of the branch, and insert the adjustment rod 303 into any one of the second arc groove 205 and the third arc groove 206. When the rotating plate 3 rotates, the adjustment rod 303 will drive the corresponding blade to move toward the U-shaped groove 201 and prune the branch. Since the shapes of the U-shaped blade 7 and the V-shaped blade 8 are different, the contours left by pruning are also different, so as to adapt to branches of different types and sizes. The operator does not need to carry multiple grafting shears of different specifications, nor does the operator need to temporarily disassemble the grafting shears to replace the blades, thereby improving the efficiency of branch pruning and grafting. ;

[0067] In this embodiment, if Figures 11 to 20As shown, the side of the fixed clamping plate 5 close to the U-shaped groove 201 is an arc-shaped contour, and the side of the slide plate 6 close to the U-shaped groove 201 is fixedly connected with a movable clamping plate 601, and the contour of the movable clamping plate 601 is adapted to the arc-shaped contour of the fixed clamping plate 5. A rectangular groove 202 is provided on the top of the sheet metal 2, and a clamping block 203 is fixedly connected to the end of the rectangular groove 202 away from the U-shaped groove 201. A baffle 603 with an L-shaped contour is fixedly connected to the side of the slide plate 6 close to the rectangular groove 202, and a limiting plate 9 is inserted into the clamping block 203. An end of the limiting plate 9 close to the clamping block 203 is fixedly connected with an inserting plate 901, and the clamping block 203 and the limiting plate 9 are fixedly connected by the inserting plate 901. A bending portion 902 is installed on the side of the limiting plate 9 close to the inserting plate 901, and the bending portion 902 has The outer wall of the plug plate 901 is fixedly connected with a return spring 905, and the two ends of the return spring 905 are respectively fixed to the plug plate 901 and the baffle plate 603. As mentioned above, when the operator inserts the adjusting rod 303 into the first arc groove 204 and the rotating plate 3 rotates, under the blocking and limiting action of the elastic sheet 602, the adjusting rod 303 will drive the slide plate 6 to move toward the U-shaped groove 201. Furthermore, since the two ends of the return spring 905 are respectively fixed to the plug plate 901 and the baffle plate 603, when the slide plate 3 rotates, the adjusting rod 303 will drive the slide plate 6 to move toward the U-shaped groove 201. When the plate 6 moves toward the position of the U-shaped groove 201, the return spring 905 is stretched and deformed, and exerts a reverse pulling force on the slide plate 6. At the same time, since the slide plate 6 is fixedly connected to the side close to the U-shaped groove 201 with the movable clamping plate 601, and the contour of the movable clamping plate 601 is adapted to the arc-shaped contour of the fixed clamping plate 5, when the movable clamping plate 601 hits the branch, the adjusting rod 303 will increase the squeezing force on the elastic sheet 602 under the blocking effect of the branch. In the process of continuous increase in the squeezing force, the elastic sheet 602 will be forced to evade and deform. After the deformation, the elastic sheet 602 cannot continue to block the adjusting rod 303. At this time, the adjusting rod 303 will pass through the elastic sheet 602 and continue to slide in the groove body on the surface of the slide plate 6; due to the elastic portion 903 on the limit plate 9 and the L-shaped contour The baffle 603 has an opposite profile, so when the slide plate 6 moves toward the U-shaped groove 201, the baffle 603 will squeeze the elastic part 903. During the squeezing process, the elastic part 903 is deformed toward the limit plate 9 and elastically avoids the baffle 603. When the movable clamping plate 601 hits the branch, the adjusting rod 303 passes through the elastic sheet 602 under the action of pressure. At this time, the adjusting rod 303 cannot continue to drive the slide plate 6 to move toward the U-shaped groove 201. Under the pulling force of the reset spring 905, the slide plate 6 will move in the opposite direction. When the slide plate 6 slides in the opposite direction, the baffle 603 will be clamped together with the elastic part 903. At this time, the elastic part 903 will block and limit the baffle 603, so that the slide plate 6 cannot continue to slide in the opposite direction, thereby achieving the clamping and fixing effect of the branch.

[0068] The adjusting rod 303 will automatically reset under the driving action of the rotating plate 3. During the resetting process, the adjusting rod 303 will squeeze the elastic sheet 602 again. Since one end of the elastic sheet 602 is fixed on the slide plate 6 and the other end is an open structure, and the elastic sheet 602 has an arc inclined inward, when the adjusting rod 303 reversely squeezes the elastic sheet 602, the elastic sheet 602 will automatically make elastic avoidance, so that the adjusting rod 303 will smoothly pass through the elastic sheet 602. This arrangement ensures that the adjusting rod 303 can be smoothly reset to the initial position, and the slide plate 6 will continue to clamp the branch, thereby achieving the positioning effect of the branch, ensuring that the grafting shears and the branch are perpendicular to each other, and improving the success rate of branch pruning. During the branch clamping process, the operator can change the position of the adjusting rod 303 and select different blades to trim the branches. Moreover, the blade will not have any impact on the movable clamping plate 601 during the process of cutting the branches. When the slide plate 6 needs to be reset, the outer pulling portion 904 is pulled outward. Under the pulling action, the lower limit plate 9 will be deformed at the position of the bending portion 902 and drive the elastic portion 903 away from the baffle 603 until the elastic portion 903 is separated from the baffle 603. Under the action of the reset spring 905, the slide plate 6 is automatically reset. Optionally, the size and length of the groove body at the position of the first arc groove 204 on the slide plate 6 are reserved to be larger, so that when the adjusting rod 303 is reset, it will not be blocked by the structure of the slide plate 6.

[0069] The working principle of the technical solution provided by the present invention is as follows:

[0070] When in use, first place the branch in the U-shaped groove 201, then insert the adjusting rod 303 into the first arc groove 204, and then press the touch paddle 107. The pressure on the touch paddle 107 will be transmitted to the micro switch 106 to turn it on. After the micro switch 106 is turned on, the battery 101 will power the motor 103. After the motor 103 is powered on, it will drive the screw rod 104 to rotate. During the rotation of the screw rod 104, under the action of the threaded drive, the lifting seat 105 will move downward on the screw rod 104 toward the position of the motor 103. Since the top of the lifting seat 105 is connected to the touch paddle 107 and the connecting rod 108, and the touch The touch paddle 107 and the connecting rod 108 are connected to the lifting seat 105 through the same rotating shaft, so the lifting seat 105 will simultaneously drive the touch paddle 107 and the connecting rod 108 to move downward together during its movement. Since the rotating plate 3 and the sheet metal 2 are rotationally connected together, and the end of the connecting rod 108 away from the lifting seat 105 is rotationally connected to the rotating plate 3, the connecting rod 108 will drive the rotating plate 3 to rotate on the sheet metal 2 during its downward movement. During the rotation of the rotating plate 3, since the U-shaped blade 7 and the V-shaped blade 8 are both provided with grooves that are adapted to the position and size of the first arc groove 204, and the slide plate 6 is located at the first arc groove An elastic sheet 602 is installed in the groove body at the position 204, and the elastic sheet 602 can block and limit the adjusting rod 303. Therefore, when the rotating plate 3 rotates, under the blocking and limiting action of the elastic sheet 602, the adjusting rod 303 will drive the slide plate 6 to move toward the U-shaped groove 201. Since the slide plate 6 is fixedly connected to the side close to the U-shaped groove 201, and the contour of the movable clamping plate 601 is adapted to the arc-shaped contour of the fixed clamping plate 5, the clamping and fixing effect of the branch can be achieved. During the process of the movable clamping plate 601 clamping the branch, the operator can change the position of the adjusting rod 303 and select different blades to clamp the branch. Pruning process, specifically, when the operator inserts the adjusting rod 303 into the second arc groove 205, since the slide plate 6 and the V-shaped blade 8 are both provided with grooves that are adapted to the position and size of the second arc groove 205, and the U-shaped blade 7 is only provided with a hole that is adapted to the size of the adjusting rod 303 at the position of the second arc groove 205, the adjusting rod 303 can be inserted into the hole on the U-shaped blade 7. When the rotating plate 3 rotates, under the blocking and limiting effect of the hole on the U-shaped blade 7, the adjusting rod 303 will drive the U-shaped blade 7 to move toward the U-shaped groove 201, and prune the branches in the U-shaped groove 201;When the operator inserts the adjustment rod 303 into the third arc groove 206, since the slide plate 6 and the U-shaped blade 7 are both provided with grooves that are adapted to the position and size of the third arc groove 206, and the V-shaped blade 8 is only provided with a hole that is adapted to the size of the adjustment rod 303 at the position of the third arc groove 206, the adjustment rod 303 can be inserted into the hole on the V-shaped blade 8. When the rotating plate 3 rotates, under the blocking and limiting action of the hole on the V-shaped blade 8, the adjustment rod 303 will drive the V-shaped blade 8 to move toward the U-shaped groove 201 and prune the branches in the U-shaped groove 201; when it is necessary to reset the slide plate 6, the outer pulling part 904 is pulled outward, and the limit plate 9 will be deformed at the position of the bending part 902 under the pulling action, and drive the elastic part 903 away from the baffle 603 until the elastic part 903 is separated from the baffle 603, and the slide plate 6 is automatically reset under the action of the reset spring 905. ;
