Description

TECHNICAL FIELD

[0001] The present application relates to a hairdressing tool, more particularly to a hair clipper with a blade assembly that can be slid out of a housing for opening and buckled to the housing. BACKGROUND

[0002] The existing hair clippers will have more or less hair fragments adhering or accumulating on the inner or outer side of the blade assembly after use. In order to prevent the hair fragments from affecting the subsequent use of the blade assembly and reducing the trimming efficiency and trimming effect of the blade assembly, the hair clippers will generally use a brush to clean the blade assembly after use to remove the hair fragments on the blade assembly of the hair clipper. There are mainly two ways to fix the trimming blade and the housing, one is fixed, that is, the blade assembly is fixedly connected with the housing. Although this installation method can avoid displacement of the blade assembly during use, it can ensure the hair trimming performance of the blade assembly and reduce vibration and working noise. However, it is not easy to clean the hair fragments adhering to the inner side of the blade assembly after use, which not only affects the subsequent use performance of the blade assembly, but also easily causes bacteria to breed in the inner side of the blade assembly in the housing. The second is disassembly, that is, the blade assembly is connected with the housing by buckling.

[0026] The embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-11 As shown, the present invention is a sliding-type hair clipper, comprising a housing 1 and a cutting head assembly 2; the cutting head assembly 2 is connected to one end of a snap-on slide 3, and the other end of the snap-on slide 3 is inserted into the housing 1 and hooked with a tripping mechanism 4, so that the cutting head assembly 2 is fixed at the port of the housing 1 and synchronously linked with a driving mechanism 5 installed in the housing 1; the cutting head assembly 2 is changed from the original structure directly connected to the housing 1 to being connected to the housing 1 through a snap-on slide 3. When in use, the snap-on slide 3 is used to hook and connect with the tripping mechanism 4 installed in the housing 1 and to the driving mechanism The structure 5 is synchronously linked to ensure the hair trimming performance of the cutter head assembly 2; and when use is completed, the buckle slide 3 can drive the tripping mechanism 4 by external force to separate the buckle slide 3 from the tripping mechanism 4, so that the buckle slide 3 can at least partially slide out of the shell 1 and push the cutter head assembly 2 out of the port of the shell 1, so that the cutter head assembly 2 and the inside of the shell 1 can be cleaned or maintained with a brush or other tools, ensuring the subsequent use of the cutter head assembly 2 while avoiding the breeding of bacteria on the inside of the cutter head assembly 2 or the inside of the shell 1, thereby improving the hygiene and safety of the hair clippers.

[0028] In order to avoid the interference caused by the reciprocating swing of the moving blade to the reciprocating swing of the moving blade, the buckle sliding seat 3 is set to be composed of the base plate 31 and the sliding arm 32. The U-shaped opening 311 is arranged on the base plate 31, the moving blade is arranged in the U-shaped opening 311, the cutter head assembly 2 is connected and fixed with the base plate 31, the interference caused by the reciprocating swing of the moving blade due to the installation is avoided, and the working stability of the cutter head assembly 2 is ensured. In order to facilitate the connection and separation of the cutter head assembly 2 and the shell 1, ensure the hair trimming performance of the cutter head assembly 2 and facilitate cleaning, the sliding arm 32 is provided with two sliding arms which are fixed on the two sides of the U-shaped opening 311 of the base plate 31 and are integrated with the base plate 31, which is convenient for integrated injection molding. The hook 321 is arranged at the end of the sliding arm 32, the hook 321 is inserted into the shell 1 and is connected with the tripping mechanism 4 to make the cutter head assembly 2 and the driving mechanism 5 installed in the shell 1 synchronous linkage, and then the hair trimming performance of the cutter head assembly 2 is ensured. When the trimming is completed, the hook 321 at the end of the sliding arm 32 is tripped from the tripping mechanism 4 by pressing the tripping mechanism 4 with external force, and the sliding arm 32 is at least partially slid out of the shell 1. In this way, the cutter head assembly 2 installed on the base plate 31 is away from the port of the shell 1 and is separated from the driving mechanism 5. At this time, the inside of the cutter head assembly 2 or the inside of the shell 1 can be cleaned by using a brush or other tools, so as to avoid the accumulation of hair in the cutter head assembly 2 or the shell 1, reduce the subsequent trimming performance of the cutter head assembly 2 or the breeding of bacteria in the shell 1, and improve the health safety of the hair clipper.

[0029] To ensure the hair trimming performance and hygiene safety of the hair clipper, the tripping mechanism 4 comprises an integrally-injected tripping button 41, a button seat 42 and a hook 44. One end of the tripping button 41 is fixed to the button seat 42 and its shape matches the shape of the tripping hole 111 on the housing 1 and is placed in the tripping hole 111. A hooking spring 45 is arranged at the bottom of the button seat 42. One end of the hooking spring 45 is pressed against the housing 1 and the other end is pressed against the button seat 42 to hook the hook 44 arranged on one side of the button seat 42 and the hook 321 at the end of the slide arm 32 of the clamping slide seat 3. Under the action of external force, the tripping button 41, the button seat 42 and the hook 44 can be displaced downward to disengage from the hook 321 at the end of the slide arm 32 of the clamping slide seat 3 so that the slide arm 32 is at least partially popped out of the housing 1. The tripping button 41 is arranged in the tripping hole 111 of the housing 1. After use, the tripping button 41 can be pressed by a finger to overcome the elastic force of the hooking spring 45 so that the tripping button 41, the button seat 42 and the hook 44 are synchronously displaced downward. The hook 44 can be disengaged from the hook 321 at the end of the slide arm 32 of the clamping slide seat 3. The slide arm 32 of the clamping slide seat 3 can be at least partially slid out of the housing 1. The cutter head assembly 2 mounted on the base plate 31 of the clamping slide seat 3 is away from the port of the housing 1. Therefore, the inside of the cutter head assembly 2 and the inside of the housing 1 can be conveniently cleaned by a cleaning tool. The accumulation of hair fragments in the cutter head assembly 2 and the housing 1 is avoided so as to ensure the hair trimming performance of the cutter head assembly 2. The inside of the cutter head assembly 2 or the inside of the housing 1 is prevented from breeding bacteria due to the accumulation of hair fragments. The hygiene safety of the hair clipper is improved. After cleaning, the cutter head assembly 2 is pushed by a hand so that the cutter head assembly 2, the base plate 31 and the slide arm 32 are displaced into the housing 1. When the hook 321 at the end of the slide arm 32 contacts the hook 44 on the button seat 42, the pushing force of the hand overcomes the elastic force of the hooking spring 45. The button seat 42 and the tripping button 41 are displaced downward. The hook 44 leaves space so that the hook 321 at the end of the slide arm 32 goes beyond the hook 44. At this time, the extrusion force of the slide arm 32 on the button seat 42 disappears. The hooking spring 45 is automatically reset to synchronously lift the button seat 42, the hook 44 and the tripping button 41 so that the hook 44 is hooked with the hook 321 at the end of the slide arm 32. At the same time, the cutter head assembly 2 is just at the port of the housing 1 and blocks the port of the housing 1. The cutter head assembly 2 is in linkage connection with the driving mechanism 5 mounted in the housing 1. Therefore, the hair trimming performance of the hair clipper is ensured.

[0030] When the handle 321 is in the unlock state, the first spring 323 is in the unlock state, and the second spring 324 is in the unlock state, so that the handle 321 can be unlocked easily. Secondly, when the inside of the cutter head assembly 2 or the inside of the shell 1 needs to be cleaned after use, the trip button 41 is pressed with a finger to disengage the hook 44 on one side of the button seat 42 from the hook 321 at the end of the slide arm 32. The trip spring 324 can drive the slide arm 32 to pop out from the shell 1 at least partially in real time, and simultaneously drive the base plate 31 of the snap slide 3 and the cutter head assembly 2 mounted on the base plate 31 to separate from the port of the shell 1. In this way, the inside of the cutter head assembly 2 and the inside of the shell 1 can be cleaned with a cleaning tool such as a brush to avoid broken hair from being stuck between the dynamic blade and the static blade of the cutter head assembly 2, thereby ensuring the hair trimming performance of the cutter head assembly 2 and avoiding the breeding of bacteria in the cutter head assembly 2 or the shell 1, thereby improving the hygiene of the hair clippers.

[0031] In order to improve the working stability of the cutter head assembly 2, the hooks 321 are arranged on the outer side walls of the two opposite sides of the sliding arm 32 relative to the open groove 322, so that the end of the sliding arm 32 forms two independent hooks 321; the clamping hooks 44 are arranged on the upper end surface of the clamping hook plate 43, and the width of the clamping hooks 44 is smaller than the width of the clamping hook plate 43, and the clamping hooks 44 are arranged on one side of the button seat 42 in two pieces and are fixed at intervals; the sliding arm 32 is inserted into the shell 1, and under the action of the hooking spring 45, the upper end surface of the clamping hook plate 43 is attached to the side surface of the sliding arm 32, so that the clamping hooks 44 are hooked and connected with the hooks 321, and when the external force drives the tripping button 41 to displace the button seat 42 downward, the clamping hook plate 43 is separated from the side surface of the sliding arm 32, so that the clamping hooks 44 are tripped from the hooks 321, and under the drive of the tripping spring 324, the sliding arm 32 is at least partially and timely popped out of the shell 1. By arranging the hooks 321 on the outer side walls of the two opposite sides of the end of the sliding arm 32, when the sliding arm 32 is inserted into the shell 1, the hooks 321 on the two opposite sides of the end of the sliding arm 32 respectively press the clamping hooks 44 on the upper end surface of the clamping hook plate 43, and the clamping hooks 44, the clamping hook plate 43, the button seat 42 and the tripping button 41 are synchronously displaced downward against the elastic force of the hooking spring 45. At this time, the hooks 321 on the two opposite sides of the end of the sliding arm 32 respectively pass over the clamping hooks 44 on the upper end surface of the clamping hook plate 43, and the pressing force of the sliding arm 32 on the clamping hooks 44 disappears. In this way, under the action of the elastic force of the hooking spring 45, the clamping hook plate 43, the button seat 42 and the tripping button 41 are synchronously displaced upward, so that the upper end surface of the clamping hook plate 43 is attached to the end surface of the sliding arm 32, and at the same time, the hooks 321 on the two opposite sides of the end of the sliding arm 32 are respectively hooked and connected with the clamping hooks 44, which ensures the firmness of the hooking connection between the sliding arm 32 and the tripping mechanism 4, thereby improving the working stability of the cutter head assembly 2. When the hair clipper is used up and needs to be cleaned, the tripping button 41 is pressed by the finger to overcome the elastic force of the hooking spring 45, the tripping button 41 drives the button seat 42 and the clamping hook plate 43 to be synchronously displaced downward, so that the clamping hooks 44 on the clamping hook plate 43 are separated from the hooks 321 on the two opposite sides of the end of the sliding arm 32, and the sliding arm 32 can be timely popped out of the shell 1 under the action of the tripping spring 324, and at the same time, the cutter head assembly 2 is pushed away from the port of the shell 1, so that the inside and outside of the cutter head assembly 2 and the inside of the shell 1 can be cleaned by a cleaning tool such as a brush, which avoids the accumulation of hair fragments to affect the hair trimming performance of the cutter head assembly 2 and prevents the growth of bacteria in the inside of the cutter head assembly 2 and the inside of the shell 1 due to the accumulation of hair fragments, thereby improving the hygiene safety of the hair clipper.

[0032] In order to facilitate the assembly of the tripping mechanism 4 and the connection and fixation of the head assembly 2 and the shell 1, the shell 1 comprises an outer shell 11 and an inner shell seat 12, the outer diameter of the inner shell seat 12 matches the inner diameter of the outer shell 11 and is installed in the outer shell 11; the tripping hole 111 is arranged on the outer shell 11 and penetrates the side wall of the outer shell 11, the driving mechanism 5 is installed on the inner shell seat 12 and at least one sliding groove 121 is arranged on the outer side wall of the inner shell seat 12, the tripping mechanism 4 is installed in the sliding groove 121 and one end of the tripping mechanism 4 is arranged in the tripping hole 111 of the outer shell 11 and protrudes out of the outer shell 11, one end of the buckle sliding seat 3 is inserted into the sliding groove 121 of the inner shell seat 12 and is connected with the tripping mechanism 4. The shell 1 is designed as a split structure, the outer shell 11 can be integrally formed as a whole structure with both ends communicating, which not only improves the overall appearance of the outer shell 11, but also ensures the overall waterproof performance of the hair clipper. The sliding groove 121 is arranged on the inner shell seat 12, which not only can fix the tripping mechanism 4 by using the sliding groove 121, but also can make the sliding arm 32 be inserted into the sliding groove 121 and be connected with the tripping mechanism 4, which ensures the working stability of the sliding arm 32 and improves the overall working performance of the hair clipper.

[0033] To ensure the hooking connection firmness of the cutter head assembly 2 and the shell 1, improve the working stability of the cutter head assembly 2, the sliding grooves 121 are respectively arranged on the side surfaces of the opposite sides of the inner shell seat 12. By arranging the sliding grooves 121 on the opposite sides of the inner shell seat 12, the sliding arms 32 on the two sides of the base plate 31 of the buckle sliding seat 3 can be respectively inserted into the sliding grooves 121 and respectively hooked and connected with the tripping mechanisms 4 arranged at the ends of the sliding grooves 121 away from the cutter head assembly 2, effectively improving the hooking connection firmness of the cutter head assembly 2 and the shell 1 and improving the overall hair cutting performance of the hair clipper. To facilitate the installation and fixation of the tripping mechanisms 4, the tripping bases 46 are arranged at the middle of the bottoms of the ends of the sliding grooves 121 away from the cutter head assembly 2, the second spring columns 47 are arranged on the tripping bases 46, the button seats 42 are installed on the tripping bases 46, the clamping hook plates 43 are respectively arranged on the two sides of the tripping bases 46 in the sliding grooves 121, one end of the hooking spring 45 is sleeved outside the second spring column 47, the other end is pressed in the button seat 42 to make the clamping hooks 44 on the clamping hook plates 43 respectively hooked and connected with the hooks 321 at the ends of the sliding arms 32, and the upper end surface of the button seat 42 is in contact with the inner surface of the outer shell 11 and the tripping button 41 is protruded out of the tripping hole 111 of the outer shell 11. By arranging the tripping bases 46 at the bottoms of the ends of the sliding grooves 121 away from the outer shell 11 and adding the second spring columns 47 on the tripping bases 46, the button seats 42 can be placed above the tripping bases 46, one end of the hooking spring 45 is sleeved on the second spring column 47, the other end is pressed in the button seat 42 to make the upper end surface of the button seat 42 in contact with the inner end surface of the outer shell 11, and the tripping button 41 is protruded out of the outer shell 11 in the tripping hole 111 of the outer shell 11. By adopting this structure, the limited space of the sliding grooves 121 can be fully utilized to ensure the assembly of the tripping mechanisms 4, optimize the overall structure of the hair clipper and reduce the production cost. At the same time, under the action of the hooking spring 45, the hooking connection firmness and working stability of the tripping mechanisms 4 and the sliding arms 32 can be effectively improved.

[0034] In order to facilitate the hooking connection and disconnection of the buckle sliding seat 3 and the tripping mechanism 4, the tripping base 46 is provided with a limiting plate 48 perpendicular to the tripping base 46, and the width of the limiting plate 48 is less than or equal to the tripping base 46; the hooking plates 43 are respectively arranged on the two sides of the limiting plate 48, and the tripping button 41, the button seat 42 and the hooking plate 43 can be lifted and lowered along the limiting plate 48 under the action of the hooking spring 45; the third spring column 49 is arranged on the side wall of the limiting plate 48 away from the tripping base 46, one end of the tripping spring 324 is sleeved on the third spring column 49, and the other end is sleeved on the first spring column 323 at the bottom of the open slot 322. The limiting plate 48 is arranged vertically on one side of the tripping base 46, and when the button seat 42 is assembled, one side of the button seat 42 is in close contact with the inner side wall of the sliding groove 121, and the other side is in close contact with the side surface of the limiting plate 48, so that the limiting plate 48 limits the lifting and lowering of the button seat 42, effectively avoids the deviation or misplacement of the button seat 42 under the pressing of the tripping button 41 and the force of the hooking spring 45, ensures the vertical lifting and lowering of the button seat 42, and improves the working stability of the tripping mechanism 4. The third spring column 49 is additionally arranged on the other side of the limiting plate 48, one end of the tripping spring 324 installed in the open slot 322 at the end of the sliding arm 32 is sleeved on the third spring column 49, and the other end is in abutment with the first spring column 323 at the bottom of the open slot 322. When the fingers press the tripping button 41 to overcome the elastic force of the hooking spring 45 and drive the button seat 42 and the hooking plate 43 to displace downward, the hook 44 on the hooking plate 43 is separated from the hook 321 at the end of the sliding arm 32, and the tripping spring 324 drives the sliding arm 32 of the buckle sliding seat 3 to at least partially pop out of the sliding groove 121 of the inner shell seat 12, and synchronously pushes the base plate 31 and the cutter head assembly 2 out of the port of the outer shell 11, so that the inner side of the cutter head assembly 2 and the inside of the outer shell 11 can be cleaned by a brush or other tool, effectively avoiding the accumulation of hair clippings affecting the hair trimming performance of the cutter head assembly 2 and preventing the breeding of bacteria in the inside of the outer shell 11 due to the accumulation of hair clippings, and improving the health and safety of the hair clipper. Secondly, when the sliding arm 32 is displaced along the sliding groove 121 of the inner shell seat 12 under the pushing force of the hand and the hooks 321 on both sides thereof are hookingly connected with the hooks 44 on the hooking plate 43, the tripping spring 324 is compressed in the open slot 322 at the end of the sliding arm 32, and is affected by the elastic force of the tripping spring 324, which can effectively improve the tension of the hooks 321 on both sides of the end of the sliding arm 32 and the hooks 44 on the hooking plate 43, ensure the firmness of the hooking connection between the buckle sliding seat 3 and the tripping mechanism 4 in the inner shell seat 12, and effectively prevent the displacement of the cutter head assembly 2 during the working process of the hair clipper and affect the hair trimming performance of the hair clipper.

[0035] In order to prevent the dislocation of the insertion of the slide arm 32 into the slide groove 121 from affecting the hooking connection stability of the hooks 321 on both sides of the end of the slide arm 32 and the clamping hooks 44 on the clamping hook plate 43, the square tube 122 is arranged in communication with the slide groove 121 at the opening of the slide groove 121 on the opposite sides of the inner shell seat 12. One end of the slide arm 32 passes through the square tube 122 and is inserted into the slide groove 121, and is placed on the upper end face of the clamping hook plate 43 installed at one end of the slide groove 121, and the hooks 321 at the end of the slide arm 32 are hooked and connected with the clamping hooks 44. The square tube 122 is additionally arranged on the end face of one side of the inner shell seat 12 and is closed in four directions and is in communication with the slide groove 121. When the slide arm 32 is inserted into the outer shell 11, the end of the slide arm 32 is placed in the slide groove 121 only after passing through the square tube 122. The square tube 122 can limit the slide arm 32 from sliding out of the slide groove 121, and ensure the connection stability of the buckle slide seat 3 and the shell 1. In order to prevent the hooks 321 on both sides of the end of the slide arm 32 from being tripped out of the clamping hooks 44 on the clamping hook plate 43 of the tripping mechanism 4 under the action of the tripping spring 324, the clamping protrusions 123 are arranged on the opposite inner walls in the square tube 122 to limit the hooks 321 when the slide arm 32 is tripped from the clamping hook plate 43. By arranging the clamping protrusions 123 on the inner walls of the square tube 122, when an external force presses the tripping button 41 to overcome the elastic force of the hooking spring 45 and simultaneously drives the button seat 42 and the clamping hook plate 43 to displace downward to make the clamping hooks 44 disengage from the hooks 321 on both sides of the end of the slide arm 32, the slide arm 32 is tripped out of the slide groove 121 under the action of the tripping spring 324. When the hooks 321 on both sides of the end of the slide arm 32 contact the clamping protrusions 123 arranged on the inner walls of the square tube 122, the clamping protrusions 123 can limit the slide arm 32 to make the slide arm 32 partially trip out of the slide groove 121, avoid the buckle slide seat 3 from being completely separated from the shell 1, ensure the continuous use of the blade head assembly 2, and effectively prevent the dislocation of the repeated hooking connection of the blade head assembly 2, improve the performance of the blade head assembly 2 and the hair clipper, and improve the performance of the hair clipper. In order to prevent the tripping spring 324 in the open slot 322 from being separated from the open slot 322, the connecting plate 124 is arranged on the upper end face of the limiting plate 48 in the slide groove 121. One end of the connecting plate 124 is connected with the limiting plate 48, and the other end is connected with the side wall of the square tube 122 as an integral structure. The connecting plate 124 is arranged in the slide groove 121 and is connected with the upper end of the limiting plate 48 at one end and is connected with the square tube 122 at the other end. When the end of the slide arm 32 passes through the square tube 122 and is inserted into the slide groove 121, the slide arm 32 is placed below the connecting plate 124. The connecting plate 124 can play the role of a cover plate for the slide arm 32, effectively prevent the tripping spring 324 from being separated from the open slot 322, and ensure the working stability of the tripping spring 324.

[0036] In order to prevent the tripping spring 324 from being ejected from the open slot 322, affecting the tripping ejection performance of the slide arm 32, a connecting block 125 with a width less than or equal to the tripping base 46 is arranged at the bottom of the slide slot 121, one end of the connecting block 125 is connected with the tripping base 46 as a whole, and the other end is fixed with the end face side wall of the square tube 122; The connecting block 125 is arranged on the tripping base 46 at the bottom of the slide slot 121, and the other end of the connecting block 125 is connected with the end face of the square tube 122, the distance between the connecting block 125 and the connecting plate 124 is the same as the thickness of the slide arm 32, when the slide arm 32 passes through the square tube 122 and is inserted into the slide slot 121, the end faces on both sides are respectively fitted with the end faces of the connecting block 125 and the connecting plate 124 to form a limit for the slide arm 32 (relative to the up and down sides of the installation direction of the tool bit assembly 2), effectively guaranteeing the hooking connection stability of the hooks 321 on both sides of the end of the slide arm 32 with the clamping hooks 44 on the clamping hook plate 43 of the tripping mechanism 4, and also effectively preventing the tripping spring 324 from being separated from the open slot 322, improving the hooking connection tension of the clamping slide seat 3 and the tripping mechanism 4 and the real-time ejection after the clamping slide seat 3 is tripped. In order to prevent the slide arm 32 from being misaligned or offset in the radial direction (relative to the left and right sides of the installation direction of the tool bit assembly 2) when inserted into the slide slot 121, affecting the hooking connection performance of the slide arm 32 and the clamping hook plate 43, a guide plate 325 is arranged on the inner side of each slide arm 32, the height of the guide plate 325 matches the inner hole of the slide slot 121 and the square tube 122, the guide plate 325 passes through the square tube 122 and is placed in the slide slot 121, and the outer side of the guide plate 325 is limited and fitted with the end face of the clamping convex 123 arranged in the square tube 122. By arranging the guide plate 325 on the inner side of each slide arm 32, when the slide arm 32 passes through the square tube 122 and is inserted into the slide slot 121, the outer side of the guide plate 325 is fitted with the end face of the clamping convex 123, so that the clamping convex 123 not only limits the hooks 321 on both sides of the end of the slide arm 32, but also cooperates with the guide plate 325 to effectively prevent the slide arm 32 from being misaligned or offset in the radial direction of the shell 1, guaranteeing the cooperation precision of the slide arm 32 and the slide slot 121 on both sides of the inner shell seat 12, and improving the working stability of the clamping slide seat 3 and the tripping mechanism 4.

[0037] In order to facilitate the cleaning of the cutter head assembly 2 and ensure the subsequent use of the hair trimming effect, the cutter head assembly 2 is fixedly connected with the base plate 31 of the buckle sliding seat 3 or can be reversibly opened. In actual use, the connection between the cutter head assembly 2 and the buckle sliding seat 3 can adopt a fixed connection mode, that is, the cutter head assembly 2 is fixedly connected with the base plate 31 of the buckle sliding seat 3 by means of screws. This connection mode can effectively prevent the cutter head assembly 2 from being dislocated or displaced along the base plate 31 and affecting the synchronous linkage with the driving mechanism 5, thereby maximizing the hair trimming performance of the reciprocating swing of the cutter head assembly 2. Secondly, a hinged connection mode can also be adopted, that is, the lower end of the cutter head assembly 2 is fixed with the base plate 31 of the buckle sliding seat 3 by means of a hinge shaft, and the upper end of the cutter head assembly 2 is provided with clamping hooks 44, which are connected with the base plate 31 by means of clamping. When the cutter head assembly 2 needs to be cleaned, the upper end of the cutter head assembly 2 is pulled by hand to make the upper end of the cutter head assembly 2 unhooked from the base plate 31, and the inner side of the cutter head assembly 2 can be cleaned without the buckle sliding seat 3 being unhooked and popped out by the unhooking mechanism 4. The specific connection mode can be determined according to user requirements or market demand, and the present embodiment is not limited further.

[0038] The above embodiments should not be considered as limiting the present application, but any improvement based on the spirit of the present application should be within the scope of protection of the present application.
