[0014] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0015] The following is combined with Figure 1 To the attached Figure 10 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0016] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a cutting assembly 30 and a cutting device, wherein the cutting device includes a motor assembly 10, a connecting assembly 20 and a cutting assembly 30, the connecting assembly 20 includes a connecting member 21, the motor assembly 10 drives the connecting member 21 to drive the connecting member 21 to rotate, and the cutting assembly 30 can be detachably mounted on the connecting member 21. When the cutting assembly 30 is mounted on the connecting member 21, it can rotate with the connecting member 21, thereby realizing the mowing function.

[0017] Furthermore, the motor assembly 10 includes a first shell 11, a second shell 12 and a motor 13. The motor 13 includes a motor body 131 and a motor shaft 132 connected to the motor body 131. The motor body 131 is the main structure of the motor 13, which is used to generate driving force, thereby driving the motor shaft 132 to rotate. The first shell 11 is connected to the second shell 12 to form a first accommodating cavity 14, and the motor body 131 is arranged in the first accommodating cavity 14; a second accommodating cavity 15 is formed on the side of the second shell 12 away from the first shell 11, and the motor shaft 132 passes through the second shell 12 and extends into the second accommodating cavity 15; the connecting assembly 20 is arranged in the second accommodating cavity 15, and the connecting member 21 is fixed on the motor shaft 132.

[0018] This embodiment is fixed to the motor main shaft 132 by the connecting member 21. The space enclosed by the connecting member 21 and the second shell 12 blocks the motor main shaft 132, thereby protecting the motor main shaft 132 and preventing grass from entering the second accommodating cavity 15, thereby preventing the cutting device from being entangled by grass on the motor main shaft 132 when mowing the grass.

[0019] like Figure 2 As shown, further, the connecting component 20 also includes a fastener 22, the connecting member 21 is provided with a mounting hole 210, the motor main shaft 132 passes through the mounting hole 210 and is fastened to the fastener 22 to fix the connecting member 21 on the motor main shaft 132, so that the connecting member 21 can rotate with the motor main shaft 132.

[0020] like Figure 2 As shown, further, a plurality of heat sinks 23 surrounding the motor main shaft 132 are provided on the side of the connecting member 21 facing the motor body 131. By providing a plurality of heat sinks 23, the heat dissipation area of the connecting member 21 is increased. When the connecting member 21 rotates, the heat sink 23 rotates synchronously to blow air to the motor body 131, enhance convection heat dissipation, improve the heat dissipation performance of the motor body 131, and prevent the motor 13 from overheating and affecting its life.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the cutting assembly 30 provided in the embodiment of the present application includes a turntable 31, a moving mechanism 32 and a cutting rope 33. The moving mechanism 32 is slidably arranged on the turntable 31, so that the moving mechanism 32 can move relative to the turntable 31. At least part of the cutting rope 33 is connected to the moving mechanism 32 and extends out of the turntable 31 to rotate, so as to rotate and cut the target cutting object such as lawn, vegetation, etc. under the drive of the turntable 31. The cutting assembly 30 also includes a first mounting portion 34 and a second mounting portion 35. The first mounting portion 34 is detachably connected to the connecting member 21, and the second mounting portion 35 is detachably connected to the cutting rope 33; the moving mechanism 32 is acted upon by an external force and moves relative to the turntable 31. During the movement, the first mounting portion 34 is disconnected from the connecting member 21, so that the first mounting portion 34 can move relative to the connecting member 21, which facilitates the disassembly and replacement of the cutting assembly 30. During the movement, the moving mechanism 32 also disconnects the second mounting portion 35 from the cutting rope 33, so that the cutting rope 33 is in a freely movable state, which facilitates the disassembly and replacement of the cutting rope 33.

[0022] In this embodiment, by using external force to drive the moving mechanism 32 to move relative to the turntable 31, the first mounting portion 34 can be removed from the connecting member 21, thereby removing the cutting assembly 30, and the cutting rope 33 can also be removed from the second mounting portion 35, thereby simplifying the method of disassembling the cutting assembly 30 and the cutting rope 33, thereby reducing disassembly time and improving disassembly efficiency.

[0023] Furthermore, in specific applications, the moving mechanism 32 can be configured to move and reset when the external force is removed. In this way, when installing the cutting rope 33 and the cutting assembly 30, the first mounting portion 34 can be docked with the connecting member 21 and the cutting rope 33 can be installed on the second mounting portion 35 by using an external force to move the moving mechanism 32. Subsequently, the external force applied to the moving mechanism 32 is removed, so that the moving mechanism 32 can reset, and the first mounting portion 34 and the connecting member 21 are in a connected state, and the second mounting portion 35 and the cutting rope 33 are in a connected state. In this case, the cutting assembly 30 is locked to the connecting member 21, and the cutting rope 33 is locked to the second mounting portion 35. The above-mentioned method of first applying an external force to cause the moving mechanism 32 to move and then removing the external force to reset the moving mechanism 32 to assemble the connecting member 21 and the cutting rope 33 can simplify the method of installing the cutting assembly 30 and the cutting rope 33, thereby reducing installation time and improving installation efficiency.

[0024] like Figure 1 and Figure 2 As shown, in some embodiments, in the radial direction of the turntable 31 (such as Figure 1 In the y direction shown in the figure, first mounting portions 34 are provided on opposite sides of the moving mechanism 32 to improve the stability of the cutting assembly 30 installed on the connecting member 21.

[0025] In specific applications, the moving mechanism 32 can be arranged to move, according to actual needs, first to a position where the first mounting portion 34 is detachable, and then to a position where the cutting rope 33 is detachable during movement; or first to a position where the cutting rope 33 is detachable, and then to a position where the first mounting portion 34 is detachable; or to a position where the first mounting portion 34 and the cutting rope 33 can be removed at the same time; for example, the displacement of the moving mechanism 32 can be changed by changing the radial dimension of the first mounting portion 34, or by changing the magnitude of the applied external force, so as to first make the first mounting portion 34 or the cutting rope 33 in a detachable state, or to make the first mounting portion 34 and the cutting rope 33 in a detachable state at the same time.

[0026] like Figure 2 、 Figure 4 and Figure 8As shown, in some embodiments, the moving mechanism 32 includes an elastic member 321 and at least one sliding member 322, the center of gravity of the sliding member 322 does not coincide with the rotation center of the turntable 31, and the sliding member 322 is subjected to centrifugal force during the rotation of the turntable 31; the elastic member 321 can generate an elastic force to limit the movement of the sliding member 322, so that the first mounting portion 34 and the connecting member 21 remain in a connected state, and the second mounting portion 35 and the cutting rope 33 remain in a connected state, and the angle between the direction of the elastic force and the direction of the centrifugal force is 0°~45°, so that the direction of the centrifugal force exerted on the sliding member 322 is roughly the same as the direction of the elastic force exerted by the elastic member 321 on the sliding member 322, thereby increasing the force to keep the first mounting portion 34 connected to the connecting member 21 during the rotation of the turntable 31, and increasing the force to keep the second mounting portion 35 and the cutting rope 33 connected.

[0027] For example, Figure 8 As shown, in an embodiment in which the number of sliding members 322 is one, one end of the elastic member 321 is connected to the sliding member 322, and the other end of the elastic member 321 is connected to the turntable 31. The direction of the elastic force is from the elastic member 321 to the sliding member 322, and the center of gravity of the sliding member 322 is located on the side of the rotation center of the turntable 31 away from the elastic member 321, and the straight line where the center of gravity of the sliding member 322 and the rotation center of the turntable 31 are located is parallel to the length direction of the elastic member 321. In this case, the direction of the centrifugal force applied to the sliding member 322 during the rotation of the turntable 31 is the same as the direction of the elastic force applied by the elastic member 321.

[0028] For example, Figure 4 As shown, in an embodiment in which there are two sliding members 322, the two sliding members 322 are respectively located on both sides of the rotation center of the turntable 31. The direction of the centrifugal force of the sliding member 322 can be understood as the direction in which the rotation center of the turntable 31 points to the center of gravity of the sliding member 322. Moreover, the angle between the direction of the centrifugal force on the sliding member 322 during the rotation of the turntable 31 and the direction of the elastic force is 45°. In this case, the direction of one of the components of the centrifugal force on the sliding member 322 is the same as the direction of the elastic force.

[0029] The above-mentioned features can increase the force maintaining the connection between the first mounting portion 34 and the connector, and increase the force maintaining the connection between the second mounting portion 35 and the cutting rope 33, during the rotation of the turntable 31. As a result, when the cutting assembly 30 rotates and the cutting rope 33 continuously cuts the target object, the cutting assembly 30 and the connector 21 remain stably locked, thereby improving the working stability of the cutting assembly 30. For example, the elastic member 321 can be an elastic object, such as a spring.

[0030] like Figure 4As shown, in some embodiments, there are two sliding members 322, and the elastic member 321 is arranged between the two sliding members 322. The two sliding members 322 are symmetrically arranged about the rotation center of the turntable 31, which can reduce the shaking of the cutting assembly 30 during rotation.

[0031] like Figure 4 As shown, in some embodiments, the sliding member 322 is provided with a pressing portion 323, and the density of the pressing portion 323 is greater than the density of the turntable 31, so that the center of gravity of the sliding member 322 deviates from the rotation center of the turntable 31, so that the center of gravity of the sliding member 322 does not coincide with the rotation center of the turntable 31, the centrifugal force applied to the pressing portion 323 is F1, and the centrifugal force applied to the edge of the turntable 31 is F2, wherein F1 is greater than F2.

[0032] It can be understood that the density of the pressing portion 323 is greater than the density of the turntable 31, so that the pressing portion 323 weighs more than the portion of the turntable 31 corresponding to the pressing portion 323, and thus the centrifugal force applied to the pressing portion 323 when the turntable 31 rotates is greater than the portion of the turntable 31 corresponding to the pressing portion 323. This can further increase the force that keeps the first mounting portion 34 connected to the connecting member 21, and increase the force that keeps the second mounting portion 35 connected to the cutting rope 33.

[0033] like Figure 2 、 Figure 4 and Figure 5 As shown, in a specific embodiment, based on an embodiment in which each sliding member 322 is provided with a pressing portion 323, and the number of sliding members 322 is two, namely a first sliding member 322a and a second sliding member 322b, the first sliding member 322a is provided with a first through hole 324, and the second sliding member 322b is provided with a second through hole 325, the cutting rope 33 passes through the first through hole 324 and the second through hole 325, and the elastic force applied by the elastic member 321 to the sliding member 322 can limit the movement of the sliding member 322 to keep the first through hole 324 and the second through hole 325 staggered along the length direction of the cutting rope 33, so that the cutting rope 33 can be squeezed and clamped. On this basis, since the density of the pressing portion 323 is greater than the density of the turntable 31, the pressing portion 323 can be made heavier than the portion of the turntable 31 corresponding to the pressing portion 323, so that the pressing portion 323 is subjected to a greater centrifugal force than the portion of the turntable 31 corresponding to the pressing portion 323, and the direction of the centrifugal force is away from the rotation center of the turntable 31, so that the sliding member 322 has a tendency to move away from the rotation center of the turntable 31, so as to reduce the overlapping area of the first through hole 324 and the second through hole 325 while keeping the first through hole 324 and the second through hole 325 misaligned, thereby increasing the force of the two sliding members 322 to cooperate in clamping the cutting rope 33, thereby preventing the cutting rope 33 from falling out when the turntable 31 rotates at high speed.

[0034] Furthermore, each slider 322 is provided with a first mounting portion 34. The first mounting portion 34 extends into the annular space enclosed by the connector 21 and is mounted to the connector 21 in a snap-fit manner. Each slider 322 tends to move away from the rotation center of the turntable 31, causing the first mounting portion 34 to also tend to move away from the rotation center of the turntable 31, thereby increasing the clamping force between the first mounting portion 34 and the connector 21. This allows the cutting assembly 30 to remain stably locked with the connector 21 even when the cutting rope 33 continuously cuts the target object while rotating at high speed, improving the operational stability of the cutting assembly 30.

[0035] like Figures 8 to 10 As shown, in some embodiments, the turntable 31 is provided with a mounting groove 31a and a first mounting channel 31b, the moving mechanism 32 is arranged in the mounting groove 31a, and the cutting rope 33 passes through the first mounting channel 31b; the moving mechanism 32 includes a second mounting portion 35 and an elastic member 321, the elastic member 321 can limit the movement of the second mounting portion 35, so that the second mounting portion 35 covers at least part of the first mounting channel 31b, so that the second mounting portion 35 presses part of the cutting rope 33 against the first mounting channel 31b; when the moving mechanism 32 moves under the action of external force, it avoids the first mounting channel 31b and drives the second mounting portion 35 to move, so that the cutting rope 33 is disconnected from the first mounting channel 31b, so that the cutting rope 33 can pass through the first mounting channel 31b and can also move freely.

[0036] In specific applications, the moving mechanism 32 moves under the action of an external force, driving the second mounting portion 35 to move and compress the elastic member 321, causing the moving mechanism 32 to avoid the first mounting channel 31b. As a result, when viewed from the mounting slot 31a to the first mounting channel 31b, the end of the first mounting channel 31b is fully exposed, allowing the cutting rope 33 to be removed or installed. After the cutting rope 33 is installed, the external force on the moving mechanism 32 is removed, and the elastic member 321 pushes the second mounting portion 35 back to its original position, causing the second mounting portion 35 to overlap with at least a portion of the first mounting channel 31b along the length of the cutting rope 33. In other words, when viewed from the mounting slot 31a to the first mounting channel 31b, the second mounting portion 35 blocks at least a portion of the first mounting channel 31b. As a result, the second mounting portion 35 and the end surface of the first mounting channel 31b facing the second mounting portion 35 jointly clamp the portion of the cutting rope 33 located between the second mounting portion 35 and the first mounting channel 31b.

[0037] For example, Figure 8As shown, the turntable 31 is provided with two first mounting channels 31b, and the two first mounting channels 31b are respectively located on opposite sides of the mounting groove 31a. Part of the cutting rope 33 is located in the mounting groove 31a, and the two ends of the cutting rope 33 respectively pass through the two first mounting channels 31b and extend from the radially opposite sides of the turntable 31.

[0038] Furthermore, the second mounting portion 35 has two corners (not shown), which are arranged along the length direction of the cutting rope 33. The second mounting portion 35 presses against the cutting rope 33, and the portion of the cutting rope 33 corresponding to the corner is squeezed to form a bent portion (not shown), which can stabilize the connection of the cutting rope 33.

[0039] like Figure 8 and Figure 9 As shown, in one embodiment, the moving mechanism 32 is provided with a notch 32a. When the moving mechanism moves under the action of an external force, the notch 32a avoids the cutting rope 33 and also avoids the first installation channel 31b, so that the port of the first installation channel 31b is exposed from one side of the notch 32a, making it easier for the cutting rope 33 to pass through the notch 32a.

[0040] Furthermore, in combination with an embodiment in which the moving mechanism 32 includes a sliding member 322, the sliding member 322 includes a main body 3221, a connecting portion 3222 and a second mounting portion 35 which are connected in sequence along the radial direction of the cutting rope 33. The main body 3221, the connecting portion 3222 and the second mounting portion 35 form a gap 32a, and the end of the sliding member 322 away from the second mounting portion 35 (which can be understood as the pressing portion 323) protrudes from the turntable 31 to facilitate pressing the sliding member 322 when external force is applied to the sliding member 322.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, the second mounting portion 35 includes a second mounting channel 351 provided on the moving mechanism 32, a portion of the cutting rope 33 is connected to the second mounting channel 351, and the two ends of the cutting rope 33 respectively pass through the two ends of the second mounting channel 351 and extend out of the radial sides of the turntable 31 respectively; when the moving mechanism 32 moves under the action of external force, the cutting rope 33 is disconnected from the second mounting channel 351.

[0042] It is understood that when the moving mechanism 32 is not subjected to external force, it can partially fix the cutting rope 33 within the second mounting channel 351. In this case, the moving mechanism 32 is in a locked state, preventing the cutting rope 33 from moving freely. However, when an external force is applied, the locked moving mechanism 32 can be switched to a movable moving mechanism 32. When the moving mechanism 32 moves relative to the rotating disk 31 under the action of the external force, the cutting rope 33 is loosened, and the cutting rope 33 can be removed.

[0043] In specific applications, the moving mechanism 32 can be set to be able to move and reset when the external force is removed. In this way, after the first mounting portion 34 is docked with the connecting member 21 and the cutting rope 33 is installed in the second mounting channel 351, the external force applied to the moving mechanism 32 can be removed, so that the movable moving mechanism 32 is switched to a locked state of the moving mechanism 32, and then the cutting rope 33 is fixed to the second mounting channel 351, so that the cutting rope 33 and the second mounting channel 351 are in a connected state.

[0044] Furthermore, in combination with the embodiment in which the first mounting portion 34 is arranged on the moving mechanism 32, when the moving mechanism 32 is not subjected to external force, the first mounting portion 34 is installed on the connecting member 21 under the action of the moving mechanism 32. Specifically, the first mounting portion 34 is installed on the connecting member 21 in a snap-fit manner.

[0045] like Figure 1 and Figure 4 As shown, in some embodiments, the second installation channel 351 is provided on the moving mechanism 32. When the cutting rope 33 and the second installation channel 351 are in a connected state, the second installation channel 351 is in the length direction of the cutting rope 33 (eg Figure 4 The cross-sectional area along the x-direction (as shown) is S1. When the cutting cord 33 and the second mounting channel 351 are disconnected, the cross-sectional area of the second mounting channel 351 along the length of the cutting cord 33 is S2, where S1 is smaller than S2. This arrangement ensures that the cutting cord 33 is stably pressed against the second mounting channel 351 when connected, and facilitates removal from the second mounting channel 351 when the cutting cord 33 is detachable. Furthermore, when the cutting cord 33 is detachable, its axial cross-sectional area is S3, which is smaller than S2, facilitating removal of the cutting cord 33.

[0046] like Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments, the second mounting channel 351 is provided on the moving mechanism 32, the vertical distance between the second mounting channel 351 and the bottom of the turntable 31 is H1, and the vertical distance between the top surface of the turntable 31 and the bottom of the turntable 31 is H2, wherein H1 is greater than H2, so that from the top view, that is, from the direction from the connector 21 to the turntable 31, the second mounting channel 351 is located above the turntable 31, and thus the turntable 31 does not block the cutting rope 33, thereby facilitating the assembly and disassembly of the cutting rope 33.

[0047] like Figure 2 、 Figure 4 and Figure 5 As shown, combined Figure 7In some embodiments, the moving mechanism 32 includes an elastic member 321, a first sliding member 322a and a second sliding member 322b. The elastic member 321 is arranged between the first sliding member 322a and the second sliding member 322b. The first sliding member 322a and the second sliding member 322b are both slidably mounted on the turntable 31. The first sliding member 322a is provided with a first through hole 324, and the second sliding member 322b is provided with a second through hole 325. The first through hole 324 and the second through hole 325 are connected to form a second mounting channel 351; the cutting rope 33 passes through the first through hole 324 and the second through hole 325, and the first sliding member 322a and the second sliding member 322b are restricted by the elastic member 321. The first and second through holes 324 and 325 are moved to maintain the misaligned arrangement of the first through hole 324 and the second through hole 325, so that the portion of the cutting rope 33 located between the first sliding member 322a and the second sliding member 322b is squeezed and clamped to form a first bend 331, thereby connecting the cutting rope 33 and the second installation channel 351 and securing the cutting rope 33. When the first and second sliding members 322a and 322b move relative to each other under the action of an external force, the first through hole 324 and the second through hole 325 overlap, thereby disconnecting the cutting rope 33 from the second installation channel 351. At this time, the cutting rope 33 is loosened and can move freely, facilitating its extraction from the second installation channel 351. In this embodiment, when the cutting rope 33 and the second installation channel 351 are connected, the elastic member 321 can provide a pre-tightening force to keep the portion of the cutting rope 33 located between the first and second sliding members 322a and 322b clamped.

[0048] Furthermore, the first sliding member 322a and the second sliding member 322b are both provided with a first mounting portion 34. When the first sliding member 322a and the second sliding member 322b move relative to each other under the action of an external force, the first mounting portion 34 provided on the first sliding member 322a and the first mounting portion 34 provided on the second sliding member 322b are driven to approach each other, so that the first mounting portion 34 is separated from the connecting member 21, thereby allowing the cutting assembly 30 to be disassembled.

[0049] In specific applications, during the installation of the cutting rope 33 and the cutting assembly 30, an external force may be first applied along the radial direction of the turntable 31 (e.g. Figure 4The first sliding member 322a and the second sliding member 322b are pressed (in the y direction shown in the figure) to move the first sliding member 322a and the second sliding member 322b to drive the two first mounting portions 34 to approach each other and make the first through hole 324 and the second through hole 325 overlap, and then the first mounting portion 34 is docked with the connecting member 21, and the cutting rope 33 is passed through the first through hole 324 and the second through hole 325. After adjusting the length of the cutting rope 33 extending out of the second mounting channel 351, the external force is removed. Due to the pressing of the first sliding member 322a and the second sliding member, the first mounting portion 34 is connected to the connecting member 21. When the movable member 322b is engaged, the elastic member 321 is located between the first sliding member 322a and the second sliding member 322b and is compressed, elastically deforming and generating an elastic force. When the external force is removed, the elastic member 321 rebounds and acts on the first sliding member 322a and the second sliding member 322b, causing the first sliding member 322a and the second sliding member 322b to move back to their original position. This drives the two first mounting portions 34 away from each other, causing the first mounting portions 34 to engage with the connecting member 21 and also causing the first through hole 324 and the second through hole 325 to be misaligned, thereby clamping the cutting rope 33. This embodiment simplifies the installation of the cutting assembly 30 and the cutting rope 33, reduces installation time, and improves installation efficiency.

[0050] Furthermore, when removing the cutting rope 33 and the cutting assembly 30, an external force is applied to press the first sliding member 322a and the second sliding member 322b in the radial direction of the rotating disk 31, causing the first sliding member 322a and the second sliding member 322b to move, thereby driving the two first mounting portions 34 toward each other and causing the first through hole 324 and the second through hole 325 to overlap. As a result, the first mounting portion 34 is disengaged from the connecting member 21, and the cutting rope 33 is loosened, thereby allowing the cutting assembly 30 and the cutting rope 33 to be removed. This embodiment simplifies the method for removing the cutting assembly 30 and the cutting rope 33, reduces disassembly time, and improves disassembly efficiency.

[0051] like Figure 1 and Figure 2 As shown, illustratively, the cutting rope 33 is located below the second accommodating cavity 15, and the connecting member 21 rotates under the drive of the motor spindle 132, and drives the turntable 31 to rotate, thereby driving the cutting rope 33 clamped in the second mounting channel 351 to rotate to cut the target cutting object.

[0052] like Figure 4 and Figure 5 As shown, in some embodiments, the turntable 31 is provided with an assembly groove 311, a first assembly hole 312 and a second assembly hole 313, the first assembly hole 312 and the second assembly hole 313 are both connected to the assembly groove 311, and in the radial direction of the turntable 31 (such as Figure 5y direction shown in the figure), the first assembly hole 312 and the second assembly hole 313 are respectively located on opposite sides of the cutting rope 33. Specifically, the first assembly hole 312 and the second assembly hole 313 are respectively located on opposite sides of the cutting rope 33 in the radial direction; the first sliding member 322a is provided with a first pressing portion 323a, and the second sliding member 322b is provided with a second pressing portion 323b. The first sliding member 322a and the second sliding member 322b are both located in the assembly groove 311, the first pressing portion 323a passes through the first assembly hole 312, and the second pressing portion 323b passes through the second assembly hole 313; the first pressing portion 323a and the second pressing portion 323b can approach each other under the action of external force to respectively drive the first sliding member 322a and the second sliding member 322b to move.

[0053] In this embodiment, part of the first sliding member 322a, part of the second sliding member 322b, and the elastic member 321 are all accommodated in the assembly groove 311, and the first pressing portion 323a connected to the first sliding member 322a and the second pressing portion 323b connected to the second sliding member 322b respectively pass through the first assembly hole 312 and the second assembly hole 313 set on the assembly groove 311, so that in the radial direction of the turntable 31, the first sliding member 322a and the first pressing portion 323a form a clamping position on a groove wall of the assembly groove 311, and the second sliding member 322b and the second pressing portion 323b form a clamping position on a groove wall of the assembly groove 311, and the second sliding member 322b and the second pressing portion 323b respectively pass through the first assembly hole 312 and the second assembly hole 313 set on the assembly groove 311. The first and second pressing portions 323a and 323b are respectively pressed against the first and second pressing portions 323a and 323b on the radial direction of the turntable 31 so as to make the first and second pressing portions 323a and 323b closer to each other.

[0054] It should be noted that the first pressing portion 323a of the first sliding member 322a and the second pressing portion 323b of the second sliding member 322b can both be understood as the pressing portion 323 of the sliding member 322, that is, the density of the first pressing portion 323a and the density of the second pressing portion 323b can be the same, and the density of the first pressing portion 323a and the density of the second pressing portion 323b are both greater than the density of the turntable 31, so that when the turntable 31 rotates, the centrifugal force exerted on the first pressing portion 323a and the centrifugal force exerted on the second pressing portion 323b are both greater than the centrifugal force exerted on the edge of the turntable 31, thereby increasing the force for keeping the clamped cutting rope 33 and increasing the connection stability between the cutting assembly 30 and the connecting member.

[0055] like Figure 2 、 Figure 3 and Figure 5As shown, exemplarily, the first sliding member 322a and the second sliding member 322b are both provided with a first mounting portion 34, and the first mounting portion 34 is located above the assembly groove 311, and when the first mounting portion 34 is clamped to the connecting member 21, the bottom surface of the connecting member 21 is abutted against the upper surface of the turntable 31, thereby reducing the shaking of the turntable 31 in the axial direction.

[0056] like Figure 2 、 Figure 4 and Figure 6 As shown, combined Figure 7 In some embodiments, the second installation channel 351 is provided on the moving mechanism 32, and the rotary disk 31 is further provided with a first channel 314 for the cutting rope 33 to pass through. The first channel 314 and the second installation channel 351 are arranged along the radial direction of the rotary disk 31 (such as Figure 6 The cutting rope 33 is arranged in the y direction as shown, and has a second bend 332. When the cutting rope 33 and the second mounting channel 351 are in a connected state, the first channel 314 and the second mounting channel 351 are staggered so that the second bend 332 is squeezed between the first channel 314 and the second mounting channel 351, thereby clamping the second bend 332. When the cutting rope 33 and the second mounting channel 351 are disconnected, the first channel 314 and the second mounting channel 351 overlap, so that the cutting rope 33 can be pulled out from the first channel 314 and the second mounting channel 351.

[0057] Exemplarily, in an embodiment in which the first through hole 324 and the second through hole 325 are combined to form the second mounting channel 351, the first through hole 324 is located between the first channel 314 and the second through hole 325, and the cutting rope 33 has a second bend 332. When the cutting rope 33 and the second mounting channel 351 are in a connected state, the first channel 314 and the first through hole 324 are staggered so that the second bend 332 is squeezed between the first channel 314 and the first through hole 324, thereby the second bend 332 is clamped.

[0058] It can be understood that when the moving mechanism 32 is in the state of locking the cutting rope 33, the first channel 314 and the first through hole 324 are misaligned along the length direction of the cutting rope 33, so that the part of the cutting rope 33 located between the first channel 314 and the first through hole 324 is squeezed by the inner wall of the first channel 314 and the inner wall of the first through hole 324, and bent to form a second bend 332.

[0059] like Figure 2 、 Figure 4 and Figure 6 As shown, combined Figure 7 In some embodiments, the second installation channel 351 is provided on the moving mechanism 32, and the rotary disk 31 is further provided with a second channel 315 for the cutting rope 33 to pass through. The second channel 315 and the second installation channel 351 are arranged along the radial direction of the rotary disk 31 (such as Figure 7The cutting rope 33 is arranged in the y direction as shown, the cutting rope 33 has a third bend 333. When the cutting rope 33 and the second installation channel 351 are in a connected state, the second channel 315 and the second installation channel 351 are staggered, and the third bend 333 is squeezed between the second channel 315 and the second installation channel 351. When the cutting rope 33 and the second installation channel 351 are disconnected, the second channel 315 and the second installation channel 351 overlap, and the cutting rope 33 can be pulled out from the second channel 315 and the second installation channel 351.

[0060] Exemplarily, in an embodiment in which the first through hole 324 and the second through hole 325 are combined to form the second mounting channel 351, the second through hole 325 is located between the second channel 315 and the first through hole 324, and the cutting rope 33 has a third bend 333. When the cutting rope 33 and the second mounting channel 351 are in a connected state, the second channel 315 and the second through hole 325 are staggered, and the third bend 333 is squeezed between the second channel 315 and the second through hole 325, so that the third bend 333 is clamped.

[0061] It can be understood that when the moving mechanism 32 is in the state of locking the cutting rope 33, the second channel 315 and the second through hole 325 are misaligned along the length direction of the cutting rope 33, so that the part of the cutting rope 33 located between the second channel 315 and the second through hole 325 is squeezed by the inner wall of the second channel 315 and the inner wall of the second through hole 325, and bent to form a third bend 333.

[0062] In this embodiment, on the basis of a portion of the cutting rope 33 being squeezed to form a first bend 331 , a second bend 332 and / or a second bend 332 may be further provided to increase the force for clamping the cutting rope 33 .

[0063] like Figure 2 、 Figure 4 and Figure 6 As shown, combined Figure 7 In one embodiment, the cutting rope 33 has a first bend 331, a second bend 332 and a second bend 333. A first channel 314 is provided at a position corresponding to the first through hole 324 on the turntable 31, and a second channel 315 is provided at a position corresponding to the second through hole 325 on the turntable 31. The first channel 314 and the second channel 315 are connected to the assembly groove 311. When the cutting rope 33 and the second installation channel 351 are in a connected state, the first bend 331, the second bend 332 and the second bend 332 are respectively clamped and squeezed, which can increase the force to fix the cutting rope 33; when the cutting rope 33 and the second installation channel 351 are disconnected, the first channel 314, the second installation channel 351 and the second channel 315 are located on the same straight line. At this time, the cutting rope 33 is loosened and the cutting rope 33 can be pulled out of the first channel 314, the second installation channel 351 and the second channel 315.

[0064] Exemplarily, the first channel 314 is a through hole or a slot, and the second channel 315 is a through hole or a slot.

[0065] For example, in the thickness direction of the turntable 31, the wall thickness of the first channel 314 and the second channel 315 has a certain thickness, which can be designed as needed, and can enable the first channel 314 to support the part of the cutting rope 33 accommodated in the first channel 314, and the second channel 315 to support the part of the cutting rope 33 accommodated in the second channel 315, so that the part of the cutting rope 33 extending out of the turntable 31 remains straight without bending.

[0066] like Figure 6 and Figure 7 As shown, for example, in the length direction of the cutting rope 33 (which can be understood as the radial direction of the turntable 31, that is, Figure 6 In the y direction shown in the figure, the first channel 314, the first through hole 324, the second through hole 325 and the second channel 315 all have a first port 316, a second port 317 and a hole section 318 located between the first port 316 and the second port 317. The inner diameters of the first port 316 and the second port 317 gradually increase in a direction away from the hole section 318 to facilitate the passage of the cutting rope 33.

[0067] like Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, the first sliding member 322a includes a first sliding body 3223 and a first extension portion 3224, the first extension portion 3224 is connected to the first sliding body 3223, and the first sliding body 3223 and the first extension portion 3224 are arranged along the length direction of the cutting rope 33 (as shown in FIG. Figure 5 The second sliding member 322b includes a second sliding body 3225 and a second extension 3226. The second extension 3226 is connected to the second sliding body 3225. The second sliding body 3225 and the second extension 3226 are arranged along the length of the cutting rope 33. Thus, the first sliding body 3223 and the second extension 3226 are arranged opposite each other, and the second sliding body 3225 and the first extension 3224 are arranged opposite each other. The first through hole 324 is provided in the first sliding body 3223, and the second through hole 325 is provided in the second sliding body 3225.

[0068] Furthermore, the elastic member 321 includes a first elastic member 3211 and a second elastic member 3212, and the first elastic member 3211 and the second elastic member 3212 are staggered along the length direction of the cutting rope 33. One end of the first elastic member 3211 elastically abuts the first sliding body 3223, and the other end of the first elastic member 3211 elastically abuts the second extension portion 3226. One end of the second elastic member 3212 elastically abuts the second sliding body 3225, and the other end of the second elastic member 3212 elastically abuts the first extension portion 3224, so that the first elastic member 3211 and the second elastic member 3212 provide elastic resistance to limit the movement of the first sliding member 322a and the second sliding member 322b, so that the cutting rope 33 is subjected to pre-tightening force, thereby keeping the cutting rope 33 in a clamped state.

[0069] Furthermore, the first sliding body 3223 and the second sliding body 3225 are both provided with a first mounting portion 34. When the first elastic member 3211 is compressed by the first sliding body 3223 and the second extension portion 3226, and the second elastic member 3212 is compressed by the second sliding body 3225 and the first extension portion 3224, the first sliding member 322a and the second sliding member 322b tend to move away from each other, so that the first mounting portion 34 tends to move in a direction away from the rotation center of the turntable 31, thereby improving the clamping stability of the first mounting portion 34 and the connecting member 21.

[0070] Exemplarily, the first sliding member 322a and the second sliding member 322b have the same structure, and the first elastic member 3211 and the second elastic member 3212 can both be elastic objects, such as springs.

[0071] like Figure 4 and Figure 5 As shown, for example, the first pressing portion 323a is integrally connected to a surface of the first sliding body 3223 that faces away from the rotation center of the turntable 31, thereby improving the connection stability between the first pressing portion 323a and the first sliding body 3223. The second pressing portion 323b is integrally connected to a surface of the second sliding body 3225 that faces away from the rotation center of the turntable 31, thereby improving the connection stability between the second pressing portion 323b and the second sliding body 3225.

[0072] like Figure 4 and Figure 5 As shown, in some embodiments, the first extension portion 3224 is provided with a first groove 3227, and a portion of the second elastic member 3212 is accommodated in the first groove 3227, effectively preventing the second elastic member 3212 from falling out of the assembly groove 311 when being compressed; and / or, the second extension portion 3226 is provided with a second groove (not shown), and a portion of the first elastic member 3211 is accommodated in the second groove, effectively preventing the first elastic member 3211 from falling out of the assembly groove 311 when being compressed.

[0073] Furthermore, a third groove (not shown) is defined on the surface of the first sliding body 3223 facing the second extension 3226. One end of the first elastic member 3211 is received in the second groove, while the other end of the first elastic member 3211 is received in the third groove, effectively preventing the first elastic member 3211 from falling out of the assembly groove 311 when compressed. A fourth groove 3228 is defined on the surface of the second sliding body 3225 facing the first extension 3224. One end of the second elastic member 3212 is received in the first groove 3227, while the other end of the second elastic member 3212 is received in the fourth groove 3228, effectively preventing the second elastic member 3212 from falling out of the assembly groove 311 when compressed.

[0074] like Figure 4 and Figure 5 As shown, the first extension portion 3224 exemplarily includes a first extension plate 32241 and a second extension plate 32242 connected at an angle. The first extension plate 32241 is located on the side of the second extension plate 32242 facing away from the turntable 31. The first extension plate 32241, the second extension plate 32242, and the bottom wall of the assembly groove 311 together form a first groove 3227. The structure of the second extension portion 3226 is the same as that of the first extension portion 3224.

[0075] Combine Figure 4 and Figure 5 In some embodiments, the first extension 3224 extends toward a side of the second sliding body 3225 to form a first protrusion (not shown). The second elastic member 3212 is partially positioned around the first protrusion. The length of the first protrusion along the length of the second elastic member 3212 is L3. When the first through-hole 324 and the second through-hole 325 overlap, the distance between the first extension 3224 and the second sliding body 3225 is L4, where L3 ≤ L4. The formation of this first protrusion not only ensures that the second elastic member 3212 can be compressed, but also effectively prevents the second elastic member 3212 from dislodging from the assembly slot 311 when compressed.

[0076] Combine Figure 4 and Figure 5 In some embodiments, the second extension 3226 extends toward a side of the first sliding body 3223 to form a second protrusion. A portion of the first elastic member 3211 is disposed around the second protrusion. The second protrusion has a length L5 along the length of the first elastic member 3211. When the first through hole 324 and the second through hole 325 overlap, the distance between the second extension 3226 and the first sliding body 3223 is L6, where L5 ≤ L6. The formation of this second protrusion not only ensures that the first elastic member 3211 can be compressed, but also effectively prevents the first elastic member 3211 from dislodging from the assembly slot 311 when compressed.

[0077] Exemplarily, the first protrusion and the second protrusion may both be columnar protrusions.

[0078] like Figure 2 and Figure 3 As shown, in some embodiments, the first mounting portion 34 is located on the side of the turntable 31 facing the connecting member 21 and is spaced apart from the turntable 31. It can be understood that when viewed from the top, that is, from the connecting member 21 to the turntable 31, the first mounting portion 34 is above the turntable 31. Specifically, in combination with Figure 5 The first mounting portion 34 is above the assembly groove 311 , which helps the first mounting portion 34 to extend into the annular space surrounded by the connecting member 21 and be engaged with the connecting member 21 when assembling the moving mechanism 32 and the connecting member 21 .

[0079] like Figure 2 、 Figure 3 and Figure 5 As shown, in some embodiments, the first mounting portion 34 includes a latching protrusion 341, and the connecting member 21 is provided with a latching groove 211 corresponding to the latching protrusion 341. Specifically, the latching groove 211 is provided on the inner peripheral wall of the connecting member 21, and the latching protrusion 341 is latched in the latching groove 211 to realize the latching connection between the first mounting portion 34 and the connecting member 21.

[0080] Illustratively, a locking protrusion 341 is integrally extended from a surface of the first sliding member 322 a away from the rotation center of the turntable 31 , and a locking protrusion 341 is integrally extended from a surface of the second sliding member 322 b away from the rotation center of the turntable 31 .

[0081] like Figure 1 and Figure 2 As shown above, it can be seen that the cutting device provided in the embodiment of the present application adopts the cutting component 30 of any of the above embodiments. By applying external force to the moving mechanism 32, the cutting component 30 can be removed from the connecting member 21, and the cutting rope 33 can also be removed from the second mounting portion 35, thereby realizing the disassembly of the cutting component 30 and the cutting rope 33.

[0082] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
