Description

Technical Field

[0001] This utility model relates to the field of Forsythia bud grafting technology, specifically a bark opener for Forsythia bud grafting. Background Technology

[0002] In the propagation of Forsythia seedlings, bud grafting is a commonly used asexual reproduction technique. Its core lies in precisely cutting the bark of the rootstock so that the scion bud patch and the cambium of the rootstock can fit closely together, thereby ensuring the grafting survival rate.

[0003] In existing technologies, most forsythia bud grafting-specific bark openers are one-piece fixed structures, lacking corresponding depth limiting mechanisms and angle positioning structures.

[0004] In actual operation, the cutting depth depends entirely on the operator's feel and experience. Due to individual differences in the thickness and bark of the Forsythia rootstock, and uneven force applied during manual operation, it is very easy to cut too deep or too shallow.

[0005] Meanwhile, the lack of clear guidance and positioning for the cutting angle makes it easy for the angle to deviate during manual advancement, resulting in crooked cuts and torn edges. This not only increases the difficulty of operation and raises the requirements for the operator's proficiency, but also seriously affects the stability of grafting quality.

[0006] In view of the above, this application is hereby submitted. Utility Model Content

[0007] The purpose of this invention is to provide a special bark opener for Forsythia bud grafting to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model provides a special bark opener for Forsythia bud grafting, including a handle, an angle adjustment mechanism fixedly installed on the side end of the handle, a housing fixedly installed on the side end of the angle adjustment mechanism, a limit mechanism rotatably installed on the side end of the housing, a connecting plate slidably installed on the side wall of the housing, a pressing plate fixedly installed on the top of the connecting plate, and a blade snapped into the bottom of the connecting plate.

[0009] The limiting mechanism includes a gear, which is rotatably mounted on the outer wall of the housing at the end away from the angle adjustment mechanism. The gear has four limiting grooves with progressively increasing depths on its side wall. Limiting blocks are slidably mounted on the inner wall of the limiting grooves. An adjusting ring is fixedly mounted on the side end of the limiting block. A bolt is rotatably mounted at the center of the adjusting ring. The outer wall of the bolt is threaded to the inner wall of the housing. The rotation of the bolt drives the adjusting ring to slide, so that the limiting block can adapt to the limiting grooves of different depths.

[0010] Furthermore, a limiting strip is fixedly installed on the side wall of the outer shell, and a sliding groove is formed on the inner wall of the limiting strip. The inner wall of the sliding groove is slidably connected to the connecting plate. The outer wall of the adjusting ring is slidably connected to the inner wall of the limiting strip. A rack is fixedly installed on the inner wall of the connecting plate, and the side wall of the rack is meshed with a gear.

[0011] Furthermore, the pressing plate is an arc-shaped plate structure, the curvature of the pressing plate is adapted to the force angle of finger pressing, the depth difference of the four limiting grooves is adapted to the common bark thickness of Forsythia rootstock, and the thickness of the limiting block is adapted to the depth of the limiting groove. Multiple depth adjustments are achieved through the limiting grooves with progressively increasing depth.

[0012] Furthermore, the angle adjustment mechanism includes a connecting rod, one end of which is fixedly connected to the handle and the other end is fixedly mounted with a toothed ring. A sliding column is fixedly mounted on the inner wall of the toothed ring, and a tension spring is sleeved on the outer wall of the sliding column. A toothed ring is rotatably connected to the side end of the tension spring. A fixing tube is fixedly mounted on the outer wall of the toothed ring, and the inner wall of the fixing tube is slidably connected to the outer wall of the sliding column. The outer wall of the fixing tube is fixedly connected to the outer shell.

[0013] Furthermore, a finger ring is rotatably mounted on the end of the grip away from the angle adjustment mechanism. The inner diameter of the finger ring is adapted to the size of the finger. The blade and the connecting plate are detachably snapped together. The blade angle is adapted to the bark cutting requirements of Forsythia suspensa bud grafting.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By utilizing the matching structure of the limiting groove and limiting block with progressive depth on the side wall of the gear, and in conjunction with the meshing transmission of the rack and gear, the downward stroke of the blade is converted into the rotation angle of the gear for precise limitation. Operators do not need to rely on feel; they can switch the depth setting by turning the bolt. This solves the core pain points of traditional tools: cutting too deep and damaging the wood, or cutting too shallow and failing to peel off the bark.

[0016] 2. Through the relative tooth groove meshing structure of toothed ring one and toothed ring two in the angle adjustment mechanism, combined with the elastic reset function of the tension spring, the cutting angle can be flexibly adjusted and stably locked. The operator can quickly adjust the blade angle according to the different growth angles of the Forsythia rootstock, avoiding the problems of skewed cuts and edge tearing caused by the lack of angle positioning in traditional tools.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5This utility model provides a technical solution: a bark opener specifically for Forsythia suspensa bud grafting, including a handle 1. An angle adjustment mechanism 2 is fixedly installed on the side of the handle 1. The angle adjustment mechanism 2 adopts a toothed ring 22 and a toothed ring 25 with opposite tooth grooves, and the tooth grooves of the toothed ring 22 and the toothed ring 25 are arranged opposite each other, replacing the traditional structure without angle adjustment. It can flexibly match different growth angles of Forsythia suspensa rootstock and avoid the skewed cut caused by the tilt of the rootstock. A shell 3 is fixedly installed on the side of the angle adjustment mechanism 2. A limiting mechanism 4 is rotatably installed on the side of the shell 3. The limiting mechanism 4 includes a gear 41, which is rotatably installed on the outer wall of the end of the shell 3 away from the angle adjustment mechanism 2. The side wall of the gear 41 has four limiting grooves 411 with progressively deeper depths. A limiting block 421 is fixedly installed on the side of the adjustment ring 42. The limiting block 421 and the limiting... The inner wall of the groove 411 is slidably connected, and the outer wall of the adjusting ring 42 is slidably connected to the side wall of the outer shell 3. A bolt 43 is rotatably installed at the center of the adjusting ring 42. The outer wall of the bolt 43 is threadedly connected to the inner wall of the outer shell 3. The rotation of the bolt 43 drives the adjusting ring 42 to slide, so that the limiting block 421 can be adapted to the limiting groove 411 of different depths. The stroke limiting scheme of gear 41, depth progressive limiting groove 411, and limiting block 421 replaces the depth judgment method that relies on manual sense. The linear cutting stroke is converted into the rotation angle control of gear 41. A connecting plate 6 is slidably installed on the side wall of the outer shell 3. A pressing plate 5 is fixedly installed on the top of the connecting plate 6. A blade 8 is snapped into the bottom of the connecting plate 6. The snapping structure between the blade 8 and the connecting plate 6 allows for quick replacement of worn blades 8, reducing tool maintenance costs. At the same time, this structure can be adapted to blades 8 with different cutting edge angles.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a special bark opener for Forsythia suspensa bud grafting, including an angle adjustment mechanism 2 comprising a connecting rod 21, one end of which is fixedly connected to a handle 1, and the other end of which is fixedly mounted with a toothed ring 22. The connecting rod 21 serves as the connecting carrier between the handle 1 and the toothed ring 22, ensuring the stability of force transmission; a sliding column 23 is fixedly mounted on the inner wall of the toothed ring 22, and a tension spring 24 is sleeved on the outer wall of the sliding column 23. A toothed ring 25 is rotatably connected to the side end of the tension spring 24. The toothed ring 22 and the toothed ring 25 engage through the relative tooth grooves on their side walls, forming a meshing connection. With a large contact area, a stable snap-fit ​​relationship can be formed, effectively preventing angle deviation after adjustment; a fixing tube 26 is fixedly installed on the outer wall of the toothed ring 25, and the inner wall of the fixing tube 26 is slidably connected to the outer wall of the sliding column 23. The sliding column 23 provides sliding guidance for the toothed ring 25 and the fixing tube 26, which not only serves to connect the outer shell 3, but also restricts the movement trajectory of the toothed ring 25. Pulling the outer shell 3 can drive the fixing tube 26 to slide along the sliding column 23, so that the toothed ring 25 is disengaged. Rotating the outer shell 3 can adjust the angle. The outer wall of the fixing tube 26 is fixedly connected to the outer shell 3.

[0026] Please see Figures 1 to 5This utility model provides a technical solution: a special bark opener for Forsythia bud grafting, including a limiting strip 31 fixedly installed on the side wall of the outer shell 3, a sliding groove 32 is provided on the inner wall of the limiting strip 31, the inner wall of the sliding groove 32 is slidably connected to the connecting plate 6, which can limit the movement trajectory of the connecting plate 6, avoid the blade 8 from shifting left and right or shaking during the cutting process, and ensure that the cut is flat and regular; the outer wall of the adjusting ring 42 is slidably connected to the inner wall of the limiting strip 31, the limiting strip 31 provides a stable sliding carrier for the adjusting ring 42, and prevents the adjusting ring 42 from getting stuck or shifting during the driving process of the bolt 43.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a special bark opener for Forsythia bud grafting, including a rack 61 fixedly installed on the inner wall of a connecting plate 6. The side wall of the rack 61 is meshed with a gear 41, which can accurately convert the linear downward movement of the connecting plate 6 driving the blade 8 into the rotational movement of the gear 41. With the limiting effect of the depth progression limiting groove 411 and the limiting block 421 on the side wall of the gear 41, the downward stroke of the connecting plate 6 can be controlled by the rotation angle of the gear 41.

[0028] Please see Figures 1 to 5 This utility model provides a technical solution: a special bark opener for Forsythia bud grafting, including a handle 1 with a finger ring 7 rotatably installed at the end away from the angle adjustment mechanism 2. The inner diameter of the finger ring 7 is adapted to the size of the fingers. The operator can insert his / her fingers into the finger ring 7 to form a double grip structure of gripping and sleeve with the handle 1, which avoids the tool from slipping due to sweaty hands or uneven force during bud grafting. The finger ring 7 and the handle 1 are rotatably connected, and the angle can be flexibly adjusted according to the operator's grip posture.

[0029] Please see Figures 1 to 5 This utility model provides a technical solution: a special bark opener for Forsythia bud grafting, including a pressing plate 5 with an arc-shaped plate structure. The arc of the pressing plate 5 is adapted to the force angle of finger pressing. The arc structure fits the natural bending shape of the finger, increasing the contact area between the finger and the pressing plate 5, which can disperse the local pressure during pressing. Moreover, the arc-shaped pressing plate 5 does not require the operator to deliberately adjust the force angle.

[0030] Please see Figures 1 to 5This utility model provides a technical solution: a bark opener specifically for Forsythia bud grafting, comprising four limiting grooves 411 with depth differences adapted to the common bark thickness of Forsythia rootstock. Operators can quickly select the corresponding depth of limiting groove 411 according to the different thicknesses and parts of Forsythia rootstock, so as to accurately control the cutting depth of the blade 8; the thickness of the limiting block 421 is adapted to the depth of the limiting groove 411, and the two are in close contact after fitting, which can strictly limit the maximum rotation angle of the gear 41, thereby locking the downward stroke of the connecting plate 6; the depth adjustment of multiple levels can be achieved through the progressively deeper limiting grooves 411, and the adjusting ring 42 can be driven to slide by rotating the bolt 43, so that the limiting block 421 can be switched to the limiting groove 411 of different depths.

[0031] Working principle: During operation, the operator holds the handle 1 and inserts their little finger into the finger ring 7 to complete the grip. By pushing the outer shell 3 in the opposite direction to the handle 1, the toothed ring 25 in the angle adjustment mechanism 2 slides along the slide post 23 and disengages from the toothed ring 22. After rotating the outer shell 3 to adjust the blade 8 to the target angle, it is released. The tension spring 24 drives the toothed ring 25 to reset and engage, completing the angle locking. Then, rotating the bolt 43 drives the adjusting ring 42 to slide along the limit strip 31, so that the limit block 421 is adapted to the side of the gear 41. The limiting groove 411 corresponding to the depth of the wall limits the downward stroke of the connecting plate 6 through the meshing transmission of gear 41 and rack 61, thereby realizing the adjustment of the cutting depth; finally, press the arc-shaped pressing plate 5, the connecting plate 6 moves down along the slide groove 32, and the blade 8 completes the skin cutting at the preset angle and depth. The gear 41 rotates until the limiting block 421 abuts the limiting groove 411 and automatically stops to avoid overcutting or undercutting. After completion, push the connecting plate 6 to reset so that the operation can be repeated, which effectively improves the accuracy and stability of bud grafting.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
