Description

Technical Field

[0001] The present invention relates to the technical field of garden cultivation, and more particularly, to a camellia cutting device. Background Art

[0002] When cultivating camellias, it is often necessary to perform girdling operations on camellias. During the girdling process, the girdling difficulty and difficulties are different for different branches. For relatively thick branches, their hardness is relatively high, and a greater force is required for girdling. For relatively thin branches, they are relatively tender. Although the force required for girdling is small, there is a problem that the cutting depth is too large, and in severe cases, the branches will be directly broken.

[0003] Currently, girdling work is usually carried out manually, which requires a high level of technical proficiency for technical workers, and there are often problems of branch damage or even branch breakage caused by improper girdling.

[0004] In view of this, the present application is specifically proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a camellia cutting device, which can effectively improve the cutting accuracy of the girdling operation, reduce the requirement for the technical proficiency of workers for the girdling operation, is applicable to the girdling operations of branches of different thicknesses, and significantly reduces the probability of branch damage or breakage caused by improper girdling. <s

[0006] The embodiments of the present invention are implemented as follows:

[0007] A camellia cutting device includes: a support end, a first half-ring body, a second half-ring body, a positioning column, an air supply mechanism, a pressure sensor, a moving seat, a girdling blade, and a controller.

[0008] One end of each of the first half-ring body and the second half-ring body is hinged to the support end, so that the first half-ring body and the second half-ring body can be separated and closed by rotating relative to each other to form a complete ring body.

[0009] Receiving grooves are provided on the inner ring walls of both the first half-ring body and the second half-ring body, and the receiving grooves are fitted with positioning columns. Along the respective radial directions of the first half-ring body and the second half-ring body, the positioning columns are slidably fitted in the receiving grooves and are slidably sealed. A first elastic member is connected between the bottom of the receiving groove and the positioning column, and the first elastic member is in an elastically stretched state.

[0010] The air supply mechanism is communicated with the receiving groove, and the pressure sensor is disposed in the receiving groove.

[0011] The side wall of the first half-ring body has a first arc-shaped rail, and the side wall of the second half-ring body has a second arc-shaped rail. When the first half-ring body and the second half-ring body are closed, the first arc-shaped rail and the second arc-shaped rail are closed to form a complete annular rail.

[0012] The moving seat is used to cooperate with the first arc rail and the second arc rail so that when the first arc rail and the second arc rail are closed, the moving seat can move along the complete annular rail. The moving seat is driven by a power mechanism, and the ring cutting blade is installed on the moving seat and the cutting depth is adjusted by a telescopic mechanism.

[0013] The air supply mechanism, the air pressure sensor, the power mechanism and the telescopic mechanism are all electrically connected to the controller.

[0014] The complete ring body is used to surround the object branch. The controller is used to control the air supply mechanism to send a preset volume of gas into the receiving groove, and the air pressure sensor is used to detect the air pressure in the receiving groove. The controller is used to determine the protruding distance of the positioning post according to the preset volume and the air pressure, and determine the diameter of the object branch according to the protruding distances of the positioning posts. The controller is also used to determine the cutting depth of the ring cutting blade according to the diameter of the object branch.

[0015] Further, a cavity is formed at one end face of the positioning post close to the bottom of the receiving groove, and the cavity extends along the axial direction of the positioning post towards the end away from the receiving groove, and the first elastic member is connected between the bottom of the receiving groove and the end wall of the cavity away from the receiving groove.

[0016] Further, the first semi-ring body is provided with an exhaust pipe, the inlet end of the exhaust pipe is communicated with the receiving groove, and the outlet end of the exhaust pipe is arranged towards the first arc rail. The exhaust pipe has a control valve, and the control valve is electrically connected to the controller.

[0017] The moving seat is provided with an air guide channel, the air guide channel penetrates through the moving seat, and the outlet end of the air guide channel is arranged towards the ring cutting blade. The moving seat has a reference state. When the moving seat is in the reference state, the moving seat is located on the first arc rail, and the inlet end of the air guide channel is communicated with the outlet end of the exhaust pipe.

[0018] Further, when the controller controls the air supply mechanism to send a preset volume of gas into the receiving groove, it is transported at a preset air supply speed.

[0019] The controller is also used to determine the movement smoothness of the positioning post according to the air pressure data detected by the air pressure sensor, including the following steps:

[0020] S1. For the positioning posts whose smoothness meets the requirements, collect the air pressure-time data during the process of sending a preset volume of gas at the preset air supply speed as the standard data.

[0021] S2. During the ring cutting process, collect the air pressure-time data during the process of sending a preset volume of gas at the preset air supply speed as the evaluation data.

[0022] S3. Compare the standard data with the evaluation data. At the same time point, if the air pressure value in the evaluation data is greater than the air pressure value in the standard data, it is determined that the movement smoothness of the positioning column is insufficient.

[0023] Further, a mounting blind hole is provided on the end face of the positioning column away from the receiving groove. A mating column is slidably fitted in the mounting blind hole, and a second elastic member is abutted between the mating column and the bottom wall of the mounting blind hole. The side wall of the mating column has a rack extending along its axial direction.

[0024] A groove is also provided on the end face of the positioning column away from the receiving groove, and the grooves are respectively arranged on opposite sides of the mounting blind hole. A notch communicating with the mounting blind hole is provided on the groove wall of the groove close to the mounting blind hole, and a mating gear is installed in the notch, and the mating gear meshes with the rack.

[0025] A contact plate is accommodated in the groove, and the contact plate is rotatably fitted to the mating gear by a connecting arm. A torsion spring is fitted between the connecting arm and the mating gear to drive the connecting arm to rotate out of the groove relative to the mating gear. A stop block is fixedly connected to the side surface of the mating gear to prevent the connecting arm from rotating out of the groove relative to the mating gear.

[0026] When the end face of the positioning column away from the receiving groove abuts against the target branch, the mating column is completely pushed into the mounting blind hole by the target branch, and the mating column drives the mating gear and makes the contact plate fit against the surface of the target branch.

[0027] Further, the surface of the contact plate is treated with anti-slip.

[0028] The beneficial effects of the technical solutions of the embodiments of the present invention include:

[0029] The camellia cutting device provided by the embodiments of the present invention can automatically determine the cutting depth according to the actual situation of the target branch, and while ensuring sufficient girdling, it avoids causing too much damage to the main part of the branch.

[0030] Generally speaking, the camellia cutting device provided by the embodiments of the present invention can effectively improve the cutting accuracy of the girdling operation, reduce the requirement for the technical proficiency of workers in the girdling operation, is applicable to the girdling operation of branches with different thicknesses, and significantly reduces the probability of branch damage or breakage caused by improper girdling.

Detailed implementation manners

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0043] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0044] The terms "first", "second", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0045] In addition, terms such as "parallel" and "perpendicular" do not mean that the components are required to be absolutely parallel or perpendicular, but can be slightly inclined. For example, "parallel" only means that its direction is more parallel relative to "perpendicular", and does not mean that the structure must be completely parallel, but can be slightly inclined.

[0046] In the description of the present invention, it should also be noted that unless otherwise clearly specified and defined, the terms "arranged", "installed", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] In order to overcome the deficiencies in the prior art, please refer to Figures 1 - 5 , this embodiment provides a camellia cutting device, which includes: a support end 100, a first semi-ring body 200, a second semi-ring body 300, a positioning column 500, a gas supply mechanism (not shown in the figure), a pressure sensor (not shown in the figure), a moving seat 600, a ring cutting blade 700, and a controller (not shown in the figure).

[0048] The support end 100 can be handheld or can adopt a robotic arm, and is not limited thereto.

[0049] Both the first semi-ring body 200 and the second semi-ring body 300 are semi-circular rings. One end of both the first semi-ring body 200 and the second semi-ring body 300 is hinged to the support end 100. The first semi-ring body 200 and the second semi-ring body 300 can rotate relative to the support end 100 so that the first semi-ring body 200 and the second semi-ring body 300 can be separated and closed by rotating relative to each other to form a complete ring body. Among them, the opening and closing of the first semi-ring body 200 and the second semi-ring body 300 are controlled by a rotation driver (not shown in the figure).

[0050] The inner ring walls of both the first semi-ring body 200 and the second semi-ring body 300 are provided with receiving grooves 410, and the receiving grooves 410 are fitted with positioning posts 500. Along the respective radial directions of the first semi-ring body 200 and the second semi-ring body 300, the positioning posts 500 are slidably fitted in the receiving grooves 410 and are slidably sealed. That is to say, for the positioning post 500 provided on the first semi-ring body 200, the positioning post 500 is arranged along the radial direction of the first semi-ring body 200 and is slidably fitted in the receiving groove 410 of the first semi-ring body 200; for the positioning post 500 provided on the second semi-ring body 300, the positioning post 500 is arranged along the radial direction of the second semi-ring body 300 and is slidably fitted in the receiving groove 410 of the second semi-ring body 300.

[0051] A first elastic member 420 is connected between the bottom of the receiving groove 410 and the positioning post 500, and the first elastic member 420 is in an elastically stretched state. Optionally, the first elastic member 420 is a tension spring, and is not limited thereto.

[0052] In the natural state, the positioning post 500 is received in the receiving groove 410. The air supply end of the air supply mechanism is communicated with the receiving groove 410 for supplying gas into the receiving groove 410, so as to push the positioning post 500 out of the receiving groove 410. A pressure sensor is arranged in the receiving groove 410, and specifically can be arranged at the bottom of the receiving groove 410 for detecting the air pressure in the receiving groove 410.

[0053] The side wall of the first semi-ring body 200 has a first arc track 430, and the side wall of the second semi-ring body 300 has a second arc track 440. The central angle degrees corresponding to both the first arc track 430 and the second arc track 440 are 180°.

[0054] When the first semi-ring body 200 is separated from the second semi-ring body 300, the first arc track 430 is separated from the second arc track 440. When the first semi-ring body 200 is closed with the second semi-ring body 300, the first arc track 430 and the second arc track 440 are also closed and form a complete circular track. In this embodiment, when the first arc track 430 and the second arc track 440 are closed, the formed complete circular track is a circular orbit.

[0055] The moving seat 600 is used to cooperate with the first arc track 430 and the second arc track 440, so that when the first arc track 430 and the second arc track 440 are closed, the moving seat 600 can move along the complete circular track. The moving seat 600 is driven by a power mechanism (not shown in the figure), and the ring cutting blade 700 is installed on the moving seat 600 and the cutting depth is adjusted by a telescopic mechanism (not shown in the figure). Specifically, the telescopic mechanism is used to adjust the position of the ring cutting blade 700 in the radial direction of the complete circular track and to adjust the position of the ring cutting blade 700 from the central axis of the complete circular track.

[0056] When the first half ring body 200 and the second half ring body 300 are closed, the complete ring body and the complete annular track are coaxially arranged.

[0057] The air supply mechanism, air pressure sensor, power mechanism and telescopic mechanism are all electrically connected to the controller and are uniformly controlled by the controller.

[0058] The complete ring body is used to be arranged around the target branch 2000, that is, the opening and closing of the first half ring body 200 and the second half ring body 300 can be controlled by controlling the rotation driver, thereby enclosing the target branch 2000 between the first half ring body 200 and the second half ring body 300.

[0059] The controller is used to control the gas delivery mechanism to deliver a preset volume of gas into each receiving slot 410, and the air pressure sensor is used to detect the air pressure within the receiving slot 410. Once the preset volume of gas is delivered to each receiving slot 410, the air pressure within the receiving slot 410 increases, pushing the positioning post 500 out of the receiving slot 410, causing the positioning post 500 to abut against the target branch 2000. In this way, the positioning post 500 can be used to lock the target branch 2000, ensuring that the complete ring body and the target branch 2000 remain as relatively static as possible, facilitating subsequent girdling operations.

[0060] At the same time, when the positioning column 500 is against the object branch 2000, the positioning column 500 cannot move further outside the receiving groove 410, and the space in the receiving groove 410 that can be used to accommodate gas is fixed. Then, conversely, the actual size of the space in the receiving groove 410 that can be used to accommodate gas can be inverted based on the final air pressure in the receiving groove 410, that is, the actual extension distance of the positioning column 500 can be determined by inversion.

[0061] Based on this, the controller is further configured to determine the extension distance of the positioning posts 500 based on the volume of gas input into the receiving tank 410 (i.e., the preset volume) and the final gas pressure after the positioning posts 500 and the target branch 2000 collide. Once the extension distance of each positioning post 500 is determined, the diameter of the target branch 2000 can be determined based on the extension distance of each positioning post 500.

[0062] Since the diameter of the target branch 2000 can be determined, once the diameter of the target branch 2000 is determined, the thickness of the cortex of the target branches 2000 of different thicknesses can be determined based on statistical data. According to the cortex thickness corresponding to branches of different thicknesses, the controller can also determine the cutting depth of the ring cutting blade 700 according to the diameter of the target branch 2000, so that during ring cutting, the cortex can be fully removed at one time without causing excessive damage to the main body of the branch.

[0063] Through the above design, the camellia cutting device can automatically determine the cutting depth according to the actual situation of the object branch 2000, ensuring sufficient girdling while avoiding excessive damage to the main part of the branch.

[0064] Among them, the actual cutting depth corresponding to branches of different thicknesses can also be flexibly adjusted according to actual needs, and the present application does not make specific restrictions.

[0065] Generally speaking, the camellia cutting device provided in this embodiment can effectively improve the cutting accuracy of the girdling operation, reduce the requirement for the technical proficiency of workers in the girdling operation, be applicable to the girdling operation of branches of different thicknesses, and significantly reduce the probability of branch damage or breakage caused by improper girdling.

[0066] In this embodiment, a cavity 510 is provided at one end face of the positioning column 500 close to the bottom of the receiving groove 410. The cavity 510 extends along the axial direction of the positioning column 500 towards the end of the positioning column 500 away from the receiving groove 410, and the first elastic member 420 is connected between the bottom of the receiving groove 410 and the end wall of the cavity 510 away from the receiving groove 410.

[0067] Through this design, the weight of the positioning column 500 can be effectively reduced. In addition, even if the length of the positioning column 500 is relatively long, in order to ensure that there is enough space for accommodating gas in the receiving groove 410, the depth of the receiving groove 410 does not need to be too deep, which is beneficial to reducing the radial dimensions of the first half ring body 200 and the second half ring body 300, and can also effectively ensure the fitting stability of the positioning column 500 in the receiving groove 410.

[0068] Furthermore, the first half ring body 200 is provided with an exhaust pipe 450. The inlet end of the exhaust pipe 450 is communicated with the receiving groove 410. Optionally, all the receiving grooves 410 are communicated with the inlet end of the exhaust pipe 450, and the exhaust is unified by the exhaust pipe 450. The main part of the exhaust pipe 450 is located on the side of the first arc track 430 away from the inner ring wall of the first half ring body 200, and the outlet end of the exhaust pipe 450 faces the first arc track 430.

[0069] The exhaust pipe 450 is provided with a control valve (not shown in the figure) for controlling the opening and closing of the exhaust pipe 450. The control valve is electrically connected to the controller and is controlled by the controller. The control valve is in a normally closed state.

[0070] The girdling blade 700 can be selected as a U-shaped blade.

[0071] The moving seat 600 is provided with a gas guiding channel 610, and the gas guiding channel 610 penetrates through the moving seat 600. The outlet end of the gas guiding channel 610 faces the girdling blade 700, and the inlet end of the gas guiding channel 610 is located on the side of the moving seat 600 away from the girdling blade 700.

[0072] Among them, the moving seat 600 has a reference state. When the moving seat 600 is in the reference state, the moving seat 600 is located on the first arc track 430, and the inlet end of the air guide channel 610 is communicated with the outlet end of the exhaust pipe 450.

[0073] When performing girdling, the position where the moving seat 600 is located in the reference state can be used as the initial position. When the moving seat 600 moves along the complete circular track for one week and returns to the position corresponding to the reference state, it means that the girdling blade 700 has cut one circle on the object branch 2000, and the girdling work of the object branch 2000 has been completed. At this time, the controller can open the control valve, and the gas in all the receiving grooves 410 can enter the air guide channel 610 uniformly through the exhaust pipe 450, and is blown towards the girdling blade 700 under the guidance of the air guide channel 610, and the air flow is used to clean the girdling blade 700, avoiding the adhesion of the branch cortex or other impurities to the girdling blade 700, thereby facilitating continuous girdling operations.

[0074] It should be noted that since the positioning column 500 was originally used to abut against the object branch 2000 to fix the object branch 2000, the space in the receiving groove 410 for accommodating gas is limited, and the air pressure in the receiving groove 410 will be relatively high. After the control valve is opened, a relatively strong air flow can be formed, effectively ensuring the cleaning effect on the girdling blade 700.

[0075] At the same time, while cleaning the girdling blade 700 with the air flow, the pressure in the receiving groove 410 is relieved. Under the action of the first elastic member 420, the positioning column 500 can fully return to the receiving groove 410 again to achieve reset, so as to facilitate the next girdling work. In addition, it is also beneficial to fully discharge the excess gas in the receiving groove 410. On the one hand, it can enhance the cleaning effect on the girdling blade 700, and on the other hand, it can avoid interfering with the determination of the diameter of the object branch 2000 in the next girdling operation.

[0076] When the gas in each receiving groove 410 is fully discharged, the controller can control the control valve to close again.

[0077] It should be noted that when the controller controls the air supply mechanism to send a preset volume of gas into the receiving groove 410, it is transported at a preset air supply speed.

[0078] The controller is also used to determine the movement smoothness of the positioning column 500 according to the air pressure data detected by the air pressure sensor, including the following steps:

[0079] S1. For the positioning posts 500 with smoothness meeting the requirements (i.e., selecting the positioning posts 500 with qualified smoothness), for such positioning posts 500, collect the air pressure-time data during the process of feeding a preset volume of gas at a preset gas supply speed as standard data.

[0080] S2. During the ring cutting process, for each positioning post 500 of the camellia cutting device in use, collect the air pressure-time data during the process of feeding a preset volume of gas into the receiving groove 410 at a preset gas supply speed as evaluation data.

[0081] S3. Compare the standard data with the evaluation data. At the same time point, if the air pressure value in the evaluation data is greater than the air pressure value in the standard data, it indicates that the protruding length of the current positioning post 500 at the same time point is less than that of the positioning post 500 with qualified smoothness, then it is determined that the movement smoothness of the positioning post 500 is insufficient.

[0082] In this way, the smoothness and smoothness of each positioning post 500 can be detected synchronously and conveniently during the ring cutting process, which can effectively ensure the normal operation of the camellia cutting device.

[0083] During the ring cutting process, for the thicker target branch 2000, its cortex hardness and thickness are usually greater, and the cutting force required is also relatively greater. For the thinner target branch 2000, its cortex hardness and thickness are usually smaller, and the cutting force required is also relatively smaller.

[0084] To better adapt to the cutting work of target branches 2000 with different thicknesses, further, please combine Figure 6 and Figure 7 , an installation blind hole 520 is provided at the end face of the positioning post 500 far from the receiving groove 410. A mating post 530 is slidably fitted in the installation blind hole 520, and a second elastic member 540 is abutted between the mating post 530 and the bottom wall of the installation blind hole 520. The side wall of the mating post 530 has a rack (not shown in the figure) extending along its axial direction. Among them, the installation blind hole 520 is coaxially arranged with the positioning post 500, the depth of the installation blind hole 520 is greater than the length of the mating post 530, the outer wall of the mating post 530 fits with the hole wall of the installation blind hole 520, and an anti-disengagement structure (not shown in the figure) is provided at the mouth of the installation blind hole 520 to prevent the mating post 530 from completely disengaging from the installation blind hole 520.

[0085] A groove 550 is also provided at the end face of the positioning post 500 far from the receiving groove 410. The grooves 550 are provided on opposite sides of the installation blind hole 520. A notch communicating with the installation blind hole 520 is provided on the side wall of the groove 550 close to the installation blind hole 520, and a mating gear 560 is installed in the notch. The mating gear 560 meshes with the rack. A part of the mating gear 560 is located in the groove 550.

[0086] A contact plate 570 is disposed in the groove 550. The contact plate 570 is rotationally fitted to the mating gear 560 by a connecting arm 580. The connecting arm 580 is fixedly connected to the contact plate 570, and one end of the connecting arm 580 away from the contact plate 570 is rotationally fitted to the mating gear 560. In this embodiment, the rotation axis line of the connecting arm 580 relative to the mating gear 560 coincides with the rotation axis line of the mating gear 560 relative to the positioning post 500.

[0087] A torsion spring (not shown in the figure) is fitted between the connecting arm 580 and the mating gear 560 to drive the connecting arm 580 to rotate out of the groove 550 relative to the mating gear 560, as Figure 6 shown in the direction of K in the figure.

[0088] A stop block 590 is fixedly connected to the side surface of the mating gear 560. In the natural state, the connecting arm 580 abuts against the stop block 590 to prevent the connecting arm 580 from rotating out of the groove 550 relative to the mating gear 560. Due to the presence of the stop block 590, under the torsion force of the torsion spring, after the connecting arm 580 abuts against the stop block 590, the connecting arm 580 and the mating gear 560 are relatively stationary.

[0089] It should be noted that the elastic force of the second elastic member 540 and the torsion force of the torsion spring are both smaller than the abutting force between the positioning post 500 and the object branch 2000.

[0090] When the end surface of the end of the positioning post 500 away from the receiving groove 410 abuts against the object branch 2000, the mating post 530 is completely pushed into the installation blind hole 520 by the object branch 2000, the second elastic member 540 is elastically compressed, and the mating post 530 drives the mating gear 560 to rotate by using the rack on its side surface. When the mating gear 560 rotates, it drives the contact plate 570 to rotate through the connecting arm 580, so that the contact plate 570 moves towards the surface of the object branch 2000 and the contact plate 570 fits against the surface of the object branch 2000.

[0091] For object branches 2000 with different thicknesses, after the positioning post 500 abuts against the object branch 2000, the mating post 530 is completely pushed into the installation blind hole 520, that is, the rotation angle of the mating gear 560 in this process is the same. If the object branch 2000 is thicker, after the contact plate 570 fits against the object branch 2000, even if the mating gear 560 continues to rotate, the contact plate 570 can drive the connecting arm 580 to deflect against the torsion force of the torsion spring, that is, the connecting arm 580 can be separated from the stop block 590 to adapt to object branches 2000 with different thicknesses.

[0092] With this design, for the thinner object branch 2000, the protruding length of the positioning post 500 is larger, and after the abutting plate 570 fits with the object branch 2000, the angle by which the abutting plate 570 rotates against the torsion of the torsion spring is smaller. The force jointly exerted by the positioning post 500 and the abutting plate 570 on the object branch 2000 is relatively small, which can fully meet the requirements for circumcision positioning of the thinner object branch 2000, and at the same time avoid damaging the branch due to excessive positioning force.

[0093] For the thicker object branch 2000, the protruding length of the positioning post 500 is smaller, and after the abutting plate 570 fits with the object branch 2000, the angle by which the abutting plate 570 rotates against the torsion of the torsion spring is larger. The force jointly exerted by the positioning post 500 and the abutting plate 570 on the object branch 2000 is relatively large, which can fully meet the requirements for circumcision positioning of the thicker object branch 2000, and at the same time avoid slipping during circumcision due to too small positioning force, ensuring the smooth progress of the circumcision operation.

[0094] Optionally, the surface of the abutting plate 570 is treated with anti-slip, so as to better fix the object branch 2000.

[0095] In summary, the camellia cutting device provided by the embodiment of the present invention can effectively improve the knife-cutting accuracy of the circumcision operation, reduce the requirement for the technical proficiency of workers for the circumcision operation, is applicable to the circumcision operation of branches of different thicknesses, and significantly reduces the probability of branch damage or breakage caused by improper circumcision.

For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
