Among them, kitchen waste has become an important part of urban solid waste, mainly produced in the process of daily cooking and dining at home, including fruit peels, vegetable leaves, leftovers and the like. This kind of garbage with high water content not only produces a large amount of leachate during transportation, but also increases the transportation cost and energy consumption. Therefore, as a kind of household appliance for reducing organic solid waste from the source, the kitchen waste processor can not only greenly dispose of kitchen waste, but also produce organic fertilizer for flower growing and other applications, further increasing economic benefits.

[0003] However, in order to achieve better grinding effect, the existing kitchen waste processor needs to prolong the grinding time or increase the grinding speed, but at the same time, it will also aggravate the wear of the cutter and increase the noise.

DETAILED DESCRIPTION

[0026] Hereinafter, the present application will be further described in conjunction with specific embodiments, and it should be noted that the following described embodiments between or between technical features can be combined to form new embodiments without conflict.

[0027] In the description of the present application, it should be noted that for orientation words, such as the terms "center", "transverse", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. The orientation and position relationship shown in the drawing is based on the orientation or position relationship, and is only for the convenience of describing the present application and simplifying the description, and cannot be understood as limiting the specific protection scope of the present application. Indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation.

[0028] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence.

[0029] The terms "include" and "have" in the specification and claims of the present application and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] As Figures 1-8It can be known that the technical scheme adopted by the application is as follows: a shearing structure 10 for a kitchen waste machine 1, comprising: a containing barrel 20 for containing to-be-processed substances; a moving cutter part 40 comprising a matching part 41 and a plurality of cutter parts 42 connected to the matching part 41, the matching part 41 being rotatably connected with the containing barrel 20 and being adapted to be driven to rotate relative to the containing barrel 20. Each cutter part 42 extends radially from the side wall of the matching part 41, and the cutter part 42 comprises a moving cutter body 421 and a grinding table 423 arranged from top to bottom, a first cutting groove 422 being formed between the moving cutter body 421 and the grinding table 423, and a grinding gap being formed between the grinding table 423 and the bottom surface of the containing barrel 20. The shearing structure 10 further comprises a fixed cutter part 30 installed on the inner wall of the containing barrel 20, and when the moving cutter part 40 rotates in the circumferential direction, at least a part of the fixed cutter part 30 passes through the first cutting groove 422.

[0031] The application sets the moving cutter body 421 and the grinding table 423 in the cutter part 42, wherein the moving cutter body 421 can cut the to-be-processed substances of a larger size, and the to-be-processed substances of small particles enter below the grinding table 423 to be ground when the cutter part 42 rotates, and the first cutting groove 422 which can cooperate with the fixed cutter part 30 is beneficial to further increase the grinding effect during rotary cutting, so as to obtain organic products with smaller particle size and increase the use performance of the shearing structure 10. Further, the fixed cutter part 30 which is cut in a staggered manner with the moving cutter part 40 is arranged in the shearing structure 10, which further increases the cutting processing strength of the to-be-processed substances and is beneficial to obtain organic products with smaller particle size and more uniform distribution.

[0032] As shown in Figures 4-5 The axis O is the rotation axis of the matching part 41, the "radial direction" in the application is the direction perpendicular to the axis O and radiating outward from the axis O, the "circumferential direction" in the application is the direction perpendicular to the axis O and perpendicular to the radial direction, and the "height direction" in the application is parallel to the axis O. It can be understood that the directions can be flexibly set according to actual needs, which are not limited herein.

[0033] As shown in Figures 4-5It can be known that, in some embodiments, the grinding table 423 has a first grinding surface 4231 and a second grinding surface 4232 oppositely arranged circumferentially, and the horizontal distance between the bottom edge of the first grinding surface 4231 and the bottom edge of the second grinding surface 4232 is greater than the horizontal distance between the top edge of the first grinding surface 4231 and the top edge of the second grinding surface 4232. It is worth mentioning that, by setting the grinding table 423 with a narrow upper part and a wide lower part, when the cutter part 42 rotates, the material to be processed in the holding barrel 20 will be collected along the side surface of the grinding table 423 to the top surface of the grinding table 423 and be cut again, thereby further increasing the crushing degree of the material to be processed, and also reducing the risk of cutter entanglement and the operation complexity of post-processing.

[0034] In contrast, in the prior art, the grinding table 423 is usually not provided with a width difference between the upper and lower surfaces, so that the material to be processed in the holding barrel 20 usually only rotates in the barrel following the cutter part 42 and is not cut, and a large amount of material to be processed accumulates at the bottom or middle position of the holding barrel 20, which is difficult to grind, further increasing the operation complexity during post-processing. Therefore, by providing the grinding table 423 with a width difference between the upper and lower surfaces, the grinding degree of the material to be processed is increased, and the accumulation phenomenon in the barrel is reduced, further reducing the risk of cutter entanglement.

[0035] In some embodiments, the horizontal distance between the first grinding surface 4231 and the second grinding surface 4232 gradually increases from top to bottom, and the inner angle between the first grinding surface 4231 and the bottom surface of the grinding table 423 is 20°-75°, specifically, the inner angle between the first grinding surface 4231 and the bottom surface of the grinding table 423 is 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, and further preferably, the inner angle between the first grinding surface 4231 and the bottom surface of the grinding table 423 is 40°-75°. The inner angle between the second grinding surface 4232 and the bottom surface of the grinding table 423 is 20°-75°, specifically, the inner angle between the second grinding surface 4232 and the bottom surface of the grinding table 423 is 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, and further preferably, the inner angle between the second grinding surface 4232 and the bottom surface of the grinding table 423 is 40°-75°. It is worth mentioning that when the first grinding surface 4231 and the second grinding surface 4232 of the grinding table 423 are provided as side surfaces with a certain degree of inclination, the substance to be treated will move to the top surface area of the grinding table 423 along the inclined side surface when the cutter portion 42 rotates, and the first cutting groove 422 can accommodate the fixed cutter portion 30 which rotates relative to the moving cutter portion 40 at this position, so that the substance to be treated is further cut and crushed when moving into the first cutting groove 422, thereby enhancing the grinding degree and the use performance of the shearing structure 10.

[0036] In some embodiments, several cutter portions 42 are arranged at equal intervals on the side wall of the fitting portion 41. It can be understood that the plurality of cutter portions 42 arranged on the side wall of the fitting portion 41 is beneficial to increase the collision probability of the cutter portion 42 and the substance to be treated, and further enhance the grinding intensity of the substance to be treated.

[0037] In some embodiments, the cutter portion 42 further comprises a shearing piece 43 which is detachably connected to the assembly surface 4233 of the top of the grinding table 423, wherein the shearing piece 43 comprises a shearing side wall 431 arranged opposite in the circumferential direction and a plurality of sharp portions 432 protruding from the shearing side wall 431 to the circumferential side. The shearing piece 43 sufficiently crushes the substance to be treated, which is beneficial to reduce the risk of entanglement of the cutter portion 42, and further improve the use stability of the shearing structure 10.

[0038] Reference Figure 6It is understood that in some embodiments, the included angle formed by the sides of the spike portion 432 is 40°~80°. Specifically, the included angle formed by the sides of the spike portion 432 is 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, or 80°. More preferably, the included angle formed by the sides of the spike portion 432 is 60°~80°. It is understood that selecting a spike portion 432 with a suitable included angle on its sides is beneficial for increasing the degree of grinding and cutting of the material to be processed.

[0039] In some embodiments, the shear sidewalls 431 are arc-shaped, and the distance between the two shear sidewalls 431 gradually increases from the middle to both ends. It should be understood that the shearing member 43, which protrudes on both sides and is recessed on the inside, can guide the material to be processed to the middle of the shear sidewall 431, and then the shearing action on the material to be processed is further enhanced by the spikes 432 provided in the middle.

[0040] In some embodiments, the edge of the moving blade body 421 away from the bottom of the container 20 is a top edge 4211, wherein the distance between the top edge 4211 and the bottom of the container 20 gradually increases from the side closer to axis O to the side farther from axis O until it remains constant. It is understood that the moving blade body 421 with its arc-shaped top edge 4211 can guide the material to be processed into the shearing zone inside the container 20, thereby reducing splashing and rebound of the material and further ensuring that the material enters the shearing working zone.

[0041] In some embodiments, such as Figures 1-3 As shown, the fixed blade section 30 includes a first fixed blade 32 and a second fixed blade 33 spaced apart. The moving blade body 421 is provided with a second cutting groove 4212, so that when the blade section 42 rotates, the first fixed blade 32 passes through the first cutting groove 422, and the second fixed blade 33 passes through the second cutting groove 4212. The radial length of the first cutting groove 422 is greater than the radial length of the second cutting groove 4212. It is worth mentioning that, because the fixed blade section 30 and the moving blade section 40 are staggered, the fixed blade section 30 and the moving blade section 40 achieve staggered rotation, thereby enhancing the grinding intensity of the material to be processed and further reducing the damage caused by insufficient grinding of the material to be processed and entanglement on the blade. On the other hand, since the radial length of the first cutting groove 422 is greater than the radial length of the second cutting groove 4212, that is, the radial length of the first fixed blade 32 is greater than the radial length of the second fixed blade 33, it is beneficial to increase the degree of pulverization of the material to be processed by providing shearing blades with different lengths.

[0042] In some embodiments, the fixed knife part 30 further comprises a fixed part 31 connecting the first fixed knife 32 and the second fixed knife 33 integrally, and the fixed part 31 is detachably connected to the inner side wall of the containing barrel 20, so that the fixed knife part 30 is detachably connected to the containing barrel 20. The first fixed knife 32 and the second fixed knife 33 respectively extend radially towards the side close to the axis O at both ends of the fixed part 31, which is beneficial to increase the grinding area and grinding effect.

[0043] In one embodiment, the radial length of the first fixed knife 32 is greater than the radial length of the second fixed knife 33. Since the first fixed knife 32 is arranged close to the bottom of the containing barrel 20, and the second fixed knife 33 is arranged away from the bottom of the containing barrel 20, it can be understood that by arranging the knives with different lengths, the cutting and crushing of the to-be-processed substances distributed in various parts of the containing barrel 20 can be performed, further reducing the accumulation of the to-be-processed substances in the containing barrel 20, and improving the crushing and grinding effect.

[0044] In at least one embodiment, the distance between the circumferentially oppositely arranged side walls of the first fixed knife 32 gradually decreases from the side close to the inner wall of the containing barrel 20 to the side away from the inner wall of the containing barrel 20. It can be understood that since the first fixed knife 32 close to the containing barrel 20 has a larger circumferential width, it is easier to drag the to-be-processed substances adhering to the inner wall of the containing barrel 20 into the containing barrel 20 for cutting. On the other hand, the gradually decreasing width of the first fixed knife 32 in the circumferential direction provides a tendency for the to-be-processed substances to move towards the axis O, that is, under the rotation of the moving knife part 40, the to-be-processed substances are easy to gradually move from the inclined surface to the inside, further reducing the risk of the to-be-processed substances adhering to the inside of the containing barrel 20.

[0045] In at least one embodiment, the circumferentially oppositely arranged side walls of the first fixed knife 32 are arc-shaped. It can be understood that the smoothness of the cutting surface in contact with the to-be-processed substances is improved, which can reduce the damage to the fixed knife part 30, further increasing the use performance and service life of the shearing structure 10.

[0046] In some embodiments, the bottom wall inside the containing barrel 20 is provided with a protrusion 22, and the bottom surface of the grinding table 423 is provided with a grinding groove 4234 matched with the protrusion 22, and the protrusion 22 is adapted to pass through the grinding groove 4234 when the grinding table 423 rotates in the circumferential direction. It can be understood that by providing a shearing area at the bottom of the containing barrel 20, the risk of the to-be-processed substances accumulating at the bottom of the containing barrel 20 is reduced, further improving the grinding degree of the to-be-processed substances.

[0047] In some embodiments, the grinding groove 4234 includes a first grinding groove 42341 and a second grinding groove 42342 arranged radially apart, the first grinding groove 42341 is close to the fitting part 41, and the second grinding groove 42342 is away from the fitting part 41. It can be understood that by providing multiple shearing areas at the bottom of the holding barrel 20, the risk of the material to be processed accumulating at the bottom of the holding barrel 20 is reduced, and the grinding degree of the material to be processed is further improved.

[0048] In some embodiments, the distance between the wall surface on the side close to the axis O of the first cutting groove 422 and the axis O is n1, the distance between the wall surface on the side close to the axis O of the first grinding groove 42341 and the axis O is n2, and the distance between the wall surface on the side close to the axis O of the second cutting groove 4212 and the axis O is n3, wherein n2≤n1<n3. It is worth mentioning that by providing shearing areas at different positions inside the holding barrel 20, the grinding degree of the material to be processed is enhanced, the risk of the material to be processed accumulating is further reduced, and the possibility of tool entanglement is reduced. On the other hand, the shearing areas with different depths are beneficial to improve the strength of the shearing force generated by the material to be processed, making the cutting process more rapid and rapid, and further enhancing the user's experience.

[0049] In some embodiments, as Figure 2 It can be seen that the protrusion 22 includes a first protrusion 221 and a second protrusion 222 arranged radially apart, when the moving cutter 40 rotates, the first protrusion 221 is adapted to pass through the first grinding groove 42341, and the second protrusion 222 is adapted to pass through the second grinding groove 42342. By adding shearing areas at the bottom of the holding barrel 20, the grinding performance of the material to be processed is improved.

[0050] In some embodiments, the fixed knife part 30 and the shearing part 43 are made of stainless steel, and the movable knife body 421, the grinding platform 423 and the matching part 41 are integrally formed by an alloy material selected from at least one of a chromium-based alloy and a tungsten-based alloy. It is worth mentioning that by selecting different materials for each cutting part in the shearing structure 10, that is, according to the different stress states, wear mechanisms and functions provided by each cutting part in the crushing process, the material performance is accurately matched, which is beneficial to improve the service life and cutting efficiency of the shearing structure 10. In other words, the movable knife body 421, the grinding platform 423 and the matching part 41 are the main execution parts of the cutting process, and when cutting the material to be processed, they will bear a high-impact effect, at this time the movable knife part 40 is prone to fatigue wear and cutting wear phenomenon, therefore, the tungsten-based alloy with good wear resistance and the chromium-based material with high hardness, high toughness and wear resistance become a good choice for the raw material of the movable knife part 40. On the other hand, since the fixed knife part 30 and the shearing part 43 are in contact with the material to be processed for a long time, the stainless steel material with high corrosion resistance becomes a good choice for the raw material of the fixed knife part 30 and the shearing part 43. Further, since the high-cost chromium-based alloy and tungsten-based alloy with high wear resistance are accurately applied to the movable knife body 421, the grinding platform 423 and the matching part 41 which are the most severely worn parts, and the stainless steel with higher cost-effectiveness is used in the fixed knife part 30 and the shearing part 43, the balance between the use performance and the manufacturing cost of the shearing structure 10 is achieved. Further, since the movable knife body 421, the grinding platform 423 and the matching part 41 are integrally formed by an alloy material, and the cost of integral forming is relatively high, the high-cost alloy material with high wear resistance is used to integrally form the movable knife body 421, the grinding platform 423 and the matching part 41, which is beneficial to increase the use stability of the overall structure, further increase the use performance of the kitchen waste machine 1, and reduce the replacement frequency of the integrally formed parts after being put into use. On the other hand, the fixed knife part 30 and the shearing part 43 are made of stainless steel, and the low production cost is beneficial to reduce the cost consumption when the fixed knife part 30 and the shearing part 43 are replaced after being worn.

[0051] As Figures 1-2 , Figure 4 , Figure 7 and Figure 8It can be known that the application further provides a kitchen garbage disposer 1, which comprises the shearing structure 10 as above; a transmission structure 50 arranged below the containing barrel 20, wherein the transmission structure 50 comprises a transmission shaft 51, the containing barrel 20 is provided with an avoiding hole 21 along an axis O, the transmission shaft 51 passes through the avoiding hole 21 and is detachably connected to the shearing structure 10, so that the transmission structure 50 can drive the rotary cutter 40 to rotate. The kitchen garbage disposer 1 further comprises a power structure (not shown in the figure) connected to the transmission structure 50, for driving the transmission structure 50 to rotate. By arranging the shearing structure 10 with good cutting performance and service life in the kitchen garbage disposer 1, the user experience is further improved during use, thereby increasing the market competitiveness.

[0052] In some embodiments, the kitchen garbage disposer 1 further comprises a quick release structure 60, the quick release structure 60 comprises the rotary cutter 40 and the transmission shaft 51, the rotary cutter 40 comprises a fitting part 41 and a plurality of cutter parts 42 connected to the fitting part 41, the fitting part 41 is suitable for being rotatably installed in the containing barrel 20 of the kitchen garbage disposer 1, the transmission shaft 51 is connected with the fitting part 41 and is suitable for driving the rotary cutter 40 to rotate, the transmission shaft 51 takes an axis O as a rotation axis, the rotary cutter 40 comprises a first locking piece 61, the fitting part 41 is provided with a first locking hole 411 matched with the first locking piece 61, the transmission shaft 51 is provided with a transmission hole 511 matched with the first locking piece 61, the first locking hole 411 and the transmission hole 511 are opposite in a direction perpendicular to the axis O, the first locking piece 61 is detachably arranged in the first locking hole 411 and the transmission hole 511, for locking or unlocking the connection between the fitting part 41 and the transmission shaft 51.

[0053] It is worth mentioning that, by arranging the quick release structure 60 in the kitchen garbage disposer 1, the rotary cutter 40 and the transmission shaft 51 are detachably connected together, which is conducive to enhancing the connection stability of the rotary cutter 40 structure in the kitchen garbage disposer 1, and can also reduce the risk of shaking of the rotary cutter 40 during rotation, thereby reducing the noise generated during use, further improving the use safety and user experience. On the other hand, since the first locking piece 61 can be arranged in or out of the first locking hole 411 and the transmission hole 511, the rotary cutter 40 and the transmission shaft 51 can be switched between the connected state and the disconnected state, which increases the convenience of disassembly and processing, is conducive to reducing the efficiency of cleaning processing after the kitchen garbage disposer 1 is used, and enhances the market competitiveness.

[0054] In some embodiments, at least one opening of the transmission hole 511 is arranged on the circumferential side of the transmission shaft 51. In the prior art, the fastener connecting the moving knife part 40 and the transmission shaft 51 is usually arranged on the top surface of the matching part 41, which occupies a large volume and is not conducive to the miniaturization of the kitchen waste machine 1. By connecting the first locking member 61 to the circumferential side of the transmission shaft 51, the overall height of the machine can be further reduced, the internal structure of the kitchen waste machine 1 is more compact, and the space utilization rate is increased. Further, when disassembling the fastener connected to the top surface of the matching part 41, the entire transmission shaft 51 often needs to be disassembled, and the operation steps are relatively cumbersome. On the other hand, when the moving knife part 40 rotates in the circumferential direction, the fastener connected to the top surface of the matching part 41 is subjected to a circumferential force, causing friction between the fastener and the matching part 41. However, under high-speed rotation and high-load impact, the connection between the fastener and the matching part 41 is prone to looseness, and even breakage due to fatigue, thereby reducing the use stability of the kitchen waste machine 1. Therefore, in the present application, the first locking member 61 passes through the transmission hole 511 arranged on the circumferential side of the transmission shaft 51, which is conducive to increasing the disassembly convenience of the kitchen waste machine 1, increasing the connection stability and use stability, and further increasing the user experience.

[0055] In some embodiments, the transmission hole 511 is arranged radially through the transmission shaft 51. It is worth mentioning that increasing the length of the transmission hole 511 is conducive to increasing the connection reliability, torsional capacity and safety of the quick-release structure 60.

[0056] In some embodiments, the moving knife part 40 further comprises a second locking member 62 arranged on the matching part 41, and the second locking member 62 is used to lock or unlock the displacement of the first locking member 61, so as to detachably connect the matching part 41 and the transmission shaft 51. It can be understood that by connecting the second locking member 62 to the first locking member 61, it is conducive to further reducing the phenomenon of looseness and falling off of the first locking member 61.

[0057] In some embodiments, the first locking member 61 is provided with a limiting hole 611 matched with the second locking member 62, the limiting hole 611 extends in a direction parallel to the axis O, and the second locking member 62 is detachably arranged in the limiting hole 611. When the second locking member 62 is movably extended to the inside of the limiting hole 611 in a direction parallel to the axis O, the first locking member 61 is in a locked state, and when the second locking member 62 is movably extended to the outside of the limiting hole 611 in a direction parallel to the axis O, the first locking member 61 is in an unlocked state. It can be understood that since the second locking member 62 can be extended to the inside of the limiting hole 611 on the first locking member 61, the centrifugal force generated during the rotation of the moving knife part 40 will affect the connection stability of the first locking member 61, and at this time the second locking member 62 connected to the first locking member 61 is conducive to sharing the force acting on the first locking member 61, thereby increasing the use safety and stability of the kitchen waste machine 1.

[0058] In the prior art, when the first locking member 61 is used alone to connect the fitting portion 41 and the transmission shaft 51, the centrifugal force generated by the rotation of the moving knife portion 40 can affect the connection stability of the first locking member 61, and even possibly throw the first locking member 61 out, at this time, the high-speed rotating moving knife portion 40 can cause damage to the inner wall of the holding barrel 20, further reducing the use safety and use stability. Therefore, the second locking member 62 extending into the limiting hole 611 in the direction parallel to the axis O is arranged, which is beneficial to increase the use stability and disassembly convenience of the quick release structure 60, and further enhance the use performance of the kitchen waste machine 1.

[0059] In some embodiments, the fitting portion 41 is provided with a second locking hole 412 extending in the direction of the axis O, and the second locking member 62 is detachably threaded into the second locking hole 412. When the first locking member 61 is in the locked state, the limiting hole 611 is opposite to the second locking hole 412, and the second locking member 62 can be adapted to be threaded into the limiting hole 611 and the second locking hole 412 at the same time. That is, when the second locking member 62 extends into the inside of the second locking hole 412 and the limiting hole 611, the first locking member 61 is in the locked state. Therefore, by arranging the first locking hole 411 and the second locking hole 412 with appropriate lengths, the connection stability of the kitchen waste machine 1 is increased.

[0060] In some embodiments, the second locking hole 412 is threadedly connected with the second locking member 62. It should be understood that the second locking hole 412 and the second locking member 62 connected by threads have good connection stability, further improving the use safety of the kitchen waste machine 1.

[0061] In some embodiments, the extension direction of the first locking hole 411 is perpendicular to the extension direction of the second locking hole 412. It is worth mentioning that by arranging two perpendicular first locking members 61 and second locking members 62, the stability of the connection structure is further enhanced, and the risk of the moving knife portion 40 and the transmission shaft 51 being disconnected due to unstable connection when the moving knife portion 40 rotates is reduced.

[0062] In some embodiments, the first locking hole 411 is arranged between two adjacent knife portions 42 and on the side wall of the fitting portion 41, and the second locking hole 412 is arranged on the top surface of the fitting portion 41 in the direction parallel to the axis O. By arranging the first locking hole 411 between the two adjacent knife portions 42, the space utilization rate inside the kitchen waste machine 1 is increased. Further, the first locking hole 411 arranged on the side and the second locking hole 412 arranged on the top surface of the fitting portion 41 are beneficial to the perpendicular connection of the first locking member 61 and the second locking member 62, thereby increasing the connection stability and use safety of the quick release structure 60.

[0063] In some embodiments, the height of the top surface of the fitting portion 41 gradually decreases from the side close to the axis O to the side away from the axis O. It is worth mentioning that the conical top surface of the fitting portion 41 is beneficial to eliminate the radial gap, so as to ensure that the rotation axis of the moving knife portion 40 coincides with the rotation axis of the transmission shaft 51, further reduce the vibration and noise generated by the kitchen waste machine 1 during use, improve the balance performance, and is beneficial to increase the use stability and use safety of the kitchen waste machine 1.

[0064] In some embodiments, the radial distance between the plane where the outer opening of the first locking hole 411 is located and the axis O is m1, and the radial distance between the plane where the outer opening of the first locking hole 411 is located and the inner side wall surface of the first locking member 61 is m2, wherein m1 < m2. It can be understood that the inner side wall surface of the first locking member 61 is the end surface of the first locking member 61 extending to the inside of the first locking hole 411, and the plane where the outer opening of the first locking hole 411 is located is the end surface of the first locking hole 411 exposed on the surface of the fitting portion 41. It can be understood that the first locking member 61 with a certain length is beneficial to improve the stability of the quick release structure 60 and reduce the risk of friction loss of the first locking member 61 caused by the rotation of the moving knife portion 40.

[0065] The above describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application.
