Description

Technical Field

[0001] The invention relates to the technical field of electric clipper heads, in particular to an electric clipper head capable of adjusting the distance between the tips of a movable blade and a fixed blade. Background Art

[0002] Electric clippers are commonly used haircutting tools in daily life and generally consist of a clipper head and the clipper body. The clipper head is the main functional component of the clipper and primarily includes a fixed blade, a movable blade, a movable blade holder, a spring bracket, and a movable blade spring. Patented blade adjustment devices and clipper heads, patent publication number CN212887712U, include an upper blade, a lower blade, a lower blade support, an adjustable movable bracket, a torsion spring, and a return spring. By moving the arms at both ends of the adjustable movable bracket, the upper blade can be moved up and down by the lower blade, thereby adjusting the cutting length. The return spring is fixedly mounted between the lower blade support and the adjustable movable bracket, providing pressure to return the clipper head movable bracket to its initial assembly position. In this utility model, the lower blade support and the torsion spring intermediate rod are designed with a curved surface at the interface. This ensures that the pressure exerted by the torsion spring on the upper blade remains constant regardless of the position of the upper blade, ensuring that the blade's sharpness and temperature rise are not affected by pressure fluctuations on the upper blade. The return spring enables the adjustable movable bracket to return to its initial position freely, thereby reducing the power for moving back.

[0003] However, since the movable knife seat is driven by the eccentric wheel shaft to make a reciprocating motion, and because the two pins of the movable knife spring are hung inside the movable knife seat, and the movable knife is fixed on the movable knife seat, the movable knife is made to swing in an arc with the two pins of the movable knife spring as a fulcrum, which causes the two ends of the serrations on the movable knife and the two ends of the serrations on the fixed knife to be tilted and misaligned. Therefore, we propose an electric clipper head with adjustable distance between the tips of the movable knife and the fixed knife to solve the above problems. Summary of the Invention

[0022] Beneficial effects

[0023] The present invention has the following beneficial effects:

[0024] 1. The electric hair clipper head with adjustable distance between the tips of the movable knife and the fixed knife can be installed on the fixed knife through the protective shell, and can also be installed on the spring bracket and the adjustment bracket. Since the bottom surface of the protective shell is movably connected to the adjustment bracket through a shaft pin, and one side of the top surface of the adjustment bracket is movably plugged into the lever on one side of the bottom surface of the spring bracket, at the same time, the two legs of the movable knife spring on the spring bracket are connected to the movable knife seat by glue, or one end of the two legs on the movable knife spring is formed into a hook shape and is stuck in the card groove on the top surface of the movable knife seat, so that one end of the two legs is connected to the movable knife seat into a whole, and the bottom surface of the movable knife seat is provided with a movable knife, so Figure 15 and Figure 16When the adjustment frame is toggled, the adjustment frame will rotate with the shaft pin on the protective shell, thereby synchronously driving the spring bracket to move back and forth, and then the position of the movable knife seat and the movable knife can be adjusted through the movable knife spring. Therefore, when the movable knife seat is connected to an external drive device, the motor in the drive device can drive the eccentric shaft to rotate, thereby driving the movable knife seat and the movable knife installed on the bottom surface of the movable knife seat to swing left and right. Since a guide mechanism is provided in the inner cavity of the slide groove, and a guide mechanism is inserted on the top surface of the guide mechanism, and the top surface of the guide mechanism is connected to the bottom surface of the movable knife, and one end of the guide mechanism is connected to the spring bracket,

[0025] 2. When the guide mechanism is stationary in the slide slot, the movable knife, driven by the eccentric shaft, moves back and forth in a straight line along the upper surface of the guide mechanism through the guide mechanism, thereby converting the swinging motion of the movable knife into a straight line reciprocating motion, thereby ensuring that the distance between the tip of the movable knife and the tip of the fixed knife is always equal. In addition, since the two legs of the movable knife spring are arc-shaped and have a certain elasticity and can be deformed when following the left and right movement of the movable knife seat, when the movable knife changes from swinging motion to straight line reciprocating motion, the guide mechanism driven by the movable knife will not be stuck in the guide mechanism, thereby improving the stability of the electric hair clipper head in cutting hair;

[0026] Since one end of the guide mechanism is connected to the spring bracket, when the front and rear position of the movable knife needs to be adjusted, the spring bracket will synchronously adjust the front and rear position of the guide mechanism. Therefore, no matter how the position of the movable knife is adjusted, the distance between the tips of the movable knife and the fixed knife will always be equal. At the same time, the bottom end of the guide mechanism will always block the slag discharge chute. When the hair debris in the chute needs to be cleaned, the adjustment frame can be turned to drive the guide mechanism to move backward in the chute, and then the bottom of the guide mechanism can be moved away from the slag discharge chute, so that the hair debris stored in the chute can be discharged from the slag discharge chute, thereby preventing the hair debris from affecting the front and rear movement of the guide mechanism.

[0027] 2. The electric shears head with adjustable distance between the tips of the movable knife and the fixed knife can install the limit bar through the guide plate in the guide mechanism, and then the limit bar can make the guide mechanism move linearly along the guide rail, thereby making the movable knife change from the original swinging arc motion to a linear reciprocating motion, so that the distance between the tips of the movable knife and the fixed knife can always be equal. The two sets of guide bars at the bottom of the guide plate can be inserted into the two sets of guide grooves, so that the guide plate can move back and forth stably in the slide groove, and then the slot can be matched with the first screw to install one end of the transmission rod, and then the other end of the transmission rod can be connected to the spring bracket through the second screw, so that the spring bracket can move back and forth while synchronously driving the guide plate to move back and forth. Through the blocking component, it can flexibly move on the movable groove and flexibly block the slag discharge groove according to the moving position of the guide plate.

[0028] 3. The electric hair clipper head with adjustable distance between the tips of the movable blade and the fixed blade, when the inner tube in the blocking assembly can be installed on the bottom surface of the guide plate through the fixing strip and can be plugged into the outer tube, then under the action of the spring, the outer tube can be flexibly extended and retracted. Since the spring is elastic, and there are multiple working gears and one cleaning gear on the bottom surface of the protective shell, and there is a protrusion on one side wall of the adjusting frame, when the protrusion on the adjusting frame moves through the multiple working gears on the protective shell, the inner tube can provide elastic force to the outer tube through the spring, so that one end of the outer tube can always block the slag discharge groove; when the hair debris in the chute needs to be cleaned, the protrusion on the adjusting frame moves backward and engages with the cleaning gear on the protective shell. At this time, the spring is in a completely relaxed state and the spring does not provide elastic force to the outer tube. Therefore, as the guide plate moves, the outer tube will move away from the slag discharge groove, so that the hair debris in the chute is discharged from the slag discharge groove.

[0029] 4. The electric clipper head with adjustable distance between the tips of the movable blade and the fixed blade can be installed on the first and second clips through the positioning plate in the guide mechanism, and can also be installed in the stepped hole through the step block, so that the positioning plate can be installed on the bottom surface of the movable blade, and then the movable blade can synchronously drive the positioning plate to swing left and right. The first and second clips can be engaged with the limit strip in the guide mechanism, so that the positioning plate will perform linear reciprocating motion along the limit strip. Through multiple mounting holes, it can cooperate with screw holes to install seven cleaning components;

[0030] When the chute needs to be cleaned, the knob block in the cleaning assembly is rotated to drive the screw to rotate, and then the pressure ring on the screw can cooperate with the seven mounting hole side walls to tightly clamp the cleaning plate, so that the positioning plate can synchronously drive the cleaning plate to move back and forth, and then the reciprocating cleaning plate can sweep the hair debris, so that the hair debris can be swept from the top of the guide plate to the slag discharge chute, so as to achieve the purpose of cleaning the hair debris. In addition, the staff can also start the motor at the same time when cleaning the hair debris, so that the moving knife moving left and right can vibrate, which is convenient for cleaning more thoroughly. At the same time, the adjusting frame can be pushed back and forth, so that the cleaning plate, outer tube and guide plate can be pushed back and forth, so that the chute can be cleaned more thoroughly.

[0031] When there is no need to clean the chute, the screw is loosened and the pressure ring will not cooperate with the side walls of the seven mounting holes to clamp the seven cleaning plates. Therefore, when the positioning plate moves back and forth, the cleaning plates will not be driven to swing significantly, thereby protecting the cleaning plates. Since the inner diameter of the socket on the cleaning plate is larger than the outer diameter of the screw, the screw can swing left and right and reduce the swing of the cleaning plates when hair debris is not being cleaned, further protecting the cleaning plates and preventing fatigue damage to the cleaning plates. The baffle can reduce the amount of hair debris entering the chute behind the guide plate, making it convenient for staff to clean the chute.

[0032] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A guide mechanism 12 is provided in the inner cavity of the slide groove 8, and one side of the guide mechanism 12 is connected to the spring bracket 3. The spring bracket 3 is used to synchronously drive the movable knife seat 6 and the guide mechanism 12 to move forward and backward when it moves forward and backward;

[0053] The top surface of the guide mechanism 12 is plugged with a guide mechanism 13, and the top surface of the guide mechanism 13 is connected to the movable knife 5. The guide mechanism 12 is used to guide the guide mechanism 13 driven by the movable knife 5 to realize the reciprocating linear movement of the movable knife 5, ensuring that the distance between the tip of the movable knife 5 and the tip of the fixed knife 1 is always equal;

[0054] A slag discharge groove 11 is provided on the bottom surface of the inner cavity of the chute 8 and on one side of the serrated end of the fixed knife 1. The slag discharge groove 11 is used to discharge hair debris that falls into the chute 8;

[0055] Through the protective shell 2, it can be installed on the fixed knife 1, and the spring bracket 3 and the adjustment bracket 4 can be installed. Since the bottom surface of the protective shell 2 is movably connected to the adjustment bracket 4 through the shaft pin, and the top surface of the adjustment bracket 4 is movably connected to the shift column on the bottom surface of the spring bracket 3, the spring bracket 3 is connected to the moving knife seat 6 through the moving knife spring 7, and the bottom surface of the moving knife seat 6 is provided with a moving knife 5, so Figure 15 and Figure 16When the adjusting frame 4 is toggled, the adjusting frame 4 will rotate with the shaft pin on the protective shell 2, thereby synchronously driving the spring bracket 3 to move back and forth, and then the position of the movable knife seat 6 and the movable knife 5 can be adjusted through the movable knife spring 7. Therefore, when the movable knife seat 6 is externally connected to a driving device, the motor in the driving device can drive the eccentric shaft to rotate, thereby driving the movable knife seat 6 and the movable knife 5 installed on the bottom surface of the movable knife seat 6 to swing left and right. Since a guide mechanism 12 is provided in the inner cavity of the slide groove 8, and a guide mechanism 13 is inserted into the top surface of the guide mechanism 12, and the top surface of the guide mechanism 13 is connected to the bottom surface of the movable knife 5, and one end of the guide mechanism 12 is connected to the spring bracket 3, when the movable knife 5 swings, the movable knife 5 makes a straight reciprocating motion along the upper surface of the guide mechanism 12 through the guide mechanism 13, thereby ensuring that the tip of the movable knife 5 The tip distance between the movable knife 5 and the fixed knife 1 is always equal, thereby improving the stability of the electric hair clipper head in cutting hair. Since one end of the guide mechanism 12 is connected to the spring bracket 3, when it is necessary to adjust the front and rear position of the movable knife 5, the spring bracket 3 will synchronously adjust the front and rear position of the guide mechanism 12. Therefore, no matter how the position of the movable knife 5 is adjusted, the tip distance between the movable knife 5 and the fixed knife 1 is always equal. At the same time, the bottom end of the guide mechanism 12 will always block the slag discharge groove 11. When it is necessary to clean the hair debris in the chute 8, the adjusting frame 4 can be toggled to drive the guide mechanism 12 to move backward in the chute 8, thereby making the bottom of the guide mechanism 12 away from the slag discharge groove 11, so that the hair debris stored in the chute 8 can be discharged from the slag discharge groove 11, thereby preventing the hair debris from affecting the front and rear movement of the guide mechanism 12.

[0056] Specifically, the guide mechanism 12 includes a guide plate 1201 disposed within the inner cavity of the chute 8. A limit bar 1202 is fixedly disposed in the middle of the top surface of the guide plate 1201, and the limit bar 1202 is movably connected to the bottom surface of the guide mechanism 13. Guide bars 1203 are disposed on both sides of the bottom surface of the guide plate 1201. Two sets of guide grooves 9 for inserting the two sets of guide bars 1203 are opened on both sides of the inner cavity of the chute 8.

[0057] Two sets of slots 1204 are symmetrically formed at the bottom of one side wall of the guide plate 1201, and a transmission rod 1205 is provided in the inner cavity of each set of slots 1204. At the same time, one end of the transmission rod 1205 is connected to the slot 1204 by a first screw 1206, and the other end of the transmission rod 1205 is connected to the spring bracket 3 by a second screw 1207;

[0058] Sealing components 1208 are provided on both sides of the middle position of the bottom surface of the guide plate 1201. The sealing components 1208 are used to seal the slag discharge chute 11. A movable groove 10 for moving the sealing component 1208 back and forth is opened on one side of the top surface of the inner cavity of the chute 8.

[0059] In this embodiment, the limit bar 1202 can be installed through the guide plate 1201 in the guide mechanism 12, and then the limit bar 1202 can make the guide mechanism 13 move linearly along the guide rail, thereby making the movable knife 5 change from the original swinging arc motion to a linear reciprocating motion, so that the distance between the tips of the movable knife 5 and the fixed knife 1 can always be equal, and the two groups of guide bars 1203 at the bottom of the guide plate 1201 can be inserted into the two groups of guide grooves 9, so that the guide plate 1201 can be The stability of the forward and backward movement in the slide groove 8, and then the slot 1204 can be used to cooperate with the first screw 1206 to install one end of the transmission rod 1205, and then the other end of the transmission rod 1205 can be connected to the spring bracket 3 through the second screw 1207, so that the spring bracket 3 can move forward and backward while synchronously driving the guide plate 1201 to move forward and backward. Through the blocking component 1208, it can not only move flexibly on the movable groove 10, but also flexibly block the slag discharge groove 11 according to the moving position of the guide plate 1201.

[0060] Specifically, the slag discharge groove 11 passes through the upper and lower surfaces of the fixed blade 1 .

[0061] In this embodiment, the residue discharge trough 11 can be used to conveniently discharge hair debris.

[0062] Specifically, the sealing assembly 1208 includes an inner tube 12081, one end of which is connected to the bottom surface of the guide plate 1201 through a fixing strip 12082, and the other end of the inner tube 12081 is connected to the outer tube 12083, and the inner cavity of the outer tube 12083 is connected to the inner cavity of the inner tube 12081 through a spring 12084.

[0063] In this embodiment, when the inner tube 12081 in the blocking component 1208 can be installed on the bottom surface of the guide plate 1201 through the fixing strip 12082, and can be plugged into the outer tube 12083, then under the action of the spring 12084, the outer tube 12083 can be flexibly extended and retracted. Since the spring 12084 is elastic, when the guide plate 1201 moves within a certain range, the inner tube 12081 can be extended and retracted to the outer tube 12083 through the spring 12084. The spring 12084 provides elastic force to the outer tube 12083, so that one end of the outer tube 12083 can always block the slag discharge groove 11. When the hair debris in the chute 8 needs to be cleaned, the guide plate 1201 is moved toward the side of the adjustment frame 4 until the spring 12084 is in a completely relaxed state. At this time, the spring 12084 will not provide elastic force to the outer tube 12083, so as the guide plate 1201 moves, the outer tube 12083 will move away from the slag discharge groove 11, so that the hair debris in the chute 8 is discharged from the slag discharge groove 11.

[0064] Specifically, the springs 12084 are arranged in multiple groups, and the multiple groups of springs 12084 are distributed in a linear array.

[0065] In this embodiment, the multiple groups of springs 12084 can provide a stable elastic force to the outer tube 12083.

[0066] Specifically, the guide mechanism 13 includes a positioning plate 1301, with a first clamping strip 1302 and a second clamping strip 1303 provided on both sides of the bottom surface of the positioning plate 1301, and the first clamping strip 1302 is located near the serrated end of the movable blade 5. A stepped block 1304 is mounted on the top surface of the positioning plate 1301 by screws, and a stepped hole 14 is provided on the top surface of the movable blade 5 for mounting the stepped block 1304. The spacing between the first clamping strip 1302 and the second clamping strip 1303 is the same as the thickness of the limiting strip 1202.

[0067] A plurality of mounting holes 1305 are provided on the outer wall surface of the first clamping strip 1302, and a screw hole 1306 is provided on the side wall of the first clamping strip 1302, and the screw hole 1306 passes through the seven mounting holes 1305, and a cleaning component 1307 is inserted into the screw hole 1306, and one side of the cleaning component 1307 is movably connected to the mounting hole 1305, and the cleaning component 1307 includes a screw 13071 rotatably connected to the inner cavity of the screw hole 1306 and seven cleaning plates 13073 arranged in the inner cavities of the seven mounting holes 1305, one end of the seven cleaning plates 13073 are inserted into the screw 13071 through the socket, and a knob block 13072 is fixedly provided at one end of the screw 13071, and a pressure ring 13074 is fixedly provided on the screw 13071 and on one side of each group of cleaning plates 13073, and the inner diameter of the socket on the cleaning plate 13073 is larger than the outer diameter of the screw 13071.

[0068] In this embodiment, the positioning plate 1301 in the guide mechanism 13 can be used to install the first clamping strip 1302 and the second clamping strip 1303, and can also be installed in the stepped hole 14 through the step block 1304, so that the positioning plate 1301 can be installed on the bottom surface of the movable knife 5, and the movable knife 5 can synchronously drive the positioning plate 1301 to swing left and right. The first clamping strip 1302 and the second clamping strip 1303 can be engaged with the limit strip 1202 in the guide mechanism 12, so that the positioning plate 1301 will make a linear reciprocating motion along the limit strip 1202. The seven cleaning components 1307 can be installed by matching the screw holes 1306 through the multiple mounting holes 1305. When it is necessary to clean the inside of the slide groove 8, the knob block 13072 in the cleaning component 1307 is rotated to drive the screw 13071 to rotate, so that the screw The pressing ring 13074 on 13071 cooperates with the side walls of the seven mounting holes 1305 to tightly clamp the cleaning plate 13073, making it convenient for the positioning plate 1301 to synchronously drive the cleaning plate 13073 to reciprocate, thereby cleaning hair debris. When the chute 8 does not need to be cleaned, the screw 13071 is loosened at this time, and the pressing ring 13074 will not cooperate with the side walls of the seven mounting holes 1305 to clamp the cleaning plate 13073. Therefore, when the positioning plate 1301 reciprocates, the cleaning plate 13073 will not be driven to swing significantly, thereby protecting the cleaning plate 13073. Since the inner diameter of the insertion hole on the cleaning plate 13073 is larger than the outer diameter of the screw 13071, the screw 13071 can swing left and right and reduce the impact on the cleaning plate 13073 when not cleaning hair debris, thereby further protecting the cleaning plate 13073.

[0069] When the cleaning assembly 1307 needs to be installed, first place the seven pressure rings 13074 and the cleaning plate 13073 in the seven mounting holes 1305, and then rotate the screw 13071 to install it on the screw hole 1306. By rotating the screw 13071, one end of the screw 13071 can pass through the seven mounting holes 1305 in sequence, so that the screw 13071 and the seven pressure rings 13074 and the seven cleaning plates 13073 can be connected in series. Then, the seven pressure rings 13074 are fixed to the screw 13071 by bonding, welding, etc., so that the pressure ring 13074 can rotate synchronously with the screw 13071, and then the pressure ring 13074 can be driven to squeeze the cleaning plate 13073 when the screw 13071 is tightened.

[0070] Specifically, the guide mechanism 13 further includes baffles 1308 disposed on the top surface of the positioning plate 1301 and close to both ends.

[0071] In this embodiment, the baffle 1308 can reduce the amount of hair debris that enters the chute 8 behind the guide plate 1201, thereby making it easier for staff to clean the chute 8.

[0072] When in use, the protective shell 2 can be installed on the fixed knife 1, and the spring bracket 3 and the adjusting bracket 4 can be installed. Since the bottom surface of the protective shell 2 is movably connected to the adjusting bracket 4 through a shaft pin, and one side of the top surface of the adjusting bracket 4 is movably plugged into the shifting column on one side of the bottom surface of the spring bracket 3, at the same time, the two legs of the movable knife spring 7 on the spring bracket 3 are connected to the movable knife seat 6 by glue, or one end of the two legs on the movable knife spring 7 is formed into a hook shape and stuck in the card groove on the top surface of the movable knife seat 6, so that one end of the two legs is connected to the movable knife seat 6 into a whole, and the bottom surface of the movable knife seat 6 is provided with a movable knife 5, so Figure 15 and Figure 16 When the adjustment frame 4 is toggled, the adjustment frame 4 will rotate with the shaft pin on the protective shell 2, thereby synchronously driving the spring bracket 3 to move back and forth, and then the position of the movable knife seat 6 and the movable knife 5 can be adjusted through the movable knife spring 7. Therefore, when the movable knife seat 6 is externally connected to a driving device, the motor in the driving device can drive the eccentric shaft to rotate, thereby driving the movable knife seat 6 and the movable knife 5 installed on the bottom surface of the movable knife seat 6 to swing left and right. Since a guide mechanism 12 is provided in the inner cavity of the slide groove 8, and a guide mechanism 13 is inserted into the top surface of the guide mechanism 12, and the top surface of the guide mechanism 13 is connected to the bottom surface of the movable knife 5, and one end of the guide mechanism 12 is connected to the spring bracket 3,

[0073] When the guide mechanism 12 is stationary in the slide groove 8, the movable knife 5 is driven by the eccentric shaft to make a straight reciprocating motion along the upper surface of the guide mechanism 12 through the guide mechanism 13, so that the movable knife 5 that is doing an arc motion can be changed into a straight reciprocating motion, thereby ensuring that the distance between the tip of the movable knife 5 and the tip of the fixed knife 1 is always equal. Moreover, since the two legs of the movable knife spring 7 are arc-shaped, and the two legs have a certain elasticity and can be deformed when following the movable knife seat 6 to move left and right, when the movable knife 5 changes from an arc motion to a straight reciprocating motion, the guide mechanism 13 driven by the movable knife 5 will not be stuck in the guide mechanism 12, so as to improve the stability of the hair cutting of the electric hair clipper head. The spring bracket 3 is connected, so when the front-back position of the movable knife 5 needs to be adjusted, the spring bracket 3 will synchronously adjust the front-back position of the guide mechanism 12. Therefore, no matter how the position of the movable knife 5 is adjusted, the distance between the tips of the movable knife 5 and the fixed knife 1 will always be equal. At the same time, the bottom end of the guide mechanism 12 will always block the slag discharge groove 11. When the hair debris in the chute 8 needs to be cleaned, the adjustment bracket 4 is turned to drive the guide mechanism 12 to move backward in the chute 8, thereby making the bottom of the guide mechanism 12 away from the slag discharge groove 11, so that the hair debris stored in the chute 8 can be discharged from the slag discharge groove 11, thereby preventing the hair debris from affecting the front-back movement of the guide mechanism 12.

[0074] The guide plate 1201 of the guide mechanism 12 can be used to install the limit bar 1202, and then the limit bar 1202 can make the guide mechanism 13 move linearly along the guide rail, thereby making the movable knife 5 change from the original swinging arc motion to a linear reciprocating motion, so that the distance between the tips of the movable knife 5 and the fixed knife 1 is always equal. The two sets of guide bars 1203 at the bottom of the guide plate 1201 can be inserted into the two sets of guide grooves 9, so that the guide plate 1201 can move back and forth stably in the slide groove 8. Then the slot 1204 can cooperate with the first screw 1206 to install one end of the transmission rod 1205, and then the other end of the transmission rod 1205 can be connected to the spring bracket 3 through the second screw 1207, so that the spring bracket 3 can move back and forth while synchronously driving the guide plate 1201 to move back and forth. Through the blocking component 1208, it can flexibly move on the movable groove 10 and flexibly block the slag discharge groove 11 according to the moving position of the guide plate 1201.

[0075] When the inner tube 12081 in the plugging assembly 1208 can be installed on the bottom surface of the guide plate 1201 through the fixing strip 12082, and can be plugged into the outer tube 12083, then under the action of the spring 12084, the outer tube 12083 can be flexibly extended and retracted. Since the spring 12084 is elastic, and there are multiple working gears and a cleaning gear on the bottom surface of the protective shell 2, and there is a protrusion on one side wall of the adjustment frame 4, when the protrusion on the adjustment frame 4 moves in the multiple working gears on the protective shell 2, the inner tube 12081 can be The spring 12084 provides elastic force to the outer tube 12083, thereby enabling one end of the outer tube 12083 to always block the slag discharge chute 11. When the hair debris in the chute 8 needs to be cleaned, the protrusion on the adjustment frame 4 moves backward to engage the cleaning gear on the protective shell 2. At this time, the spring 12084 is in a completely relaxed state and does not provide elastic force to the outer tube 12083. Therefore, as the guide plate 1201 moves, the outer tube 12083 moves away from the slag discharge chute 11, allowing the hair debris in the chute 8 to be discharged from the slag discharge chute 11.

[0076] The first clamping strip 1302 and the second clamping strip 1303 can be installed through the positioning plate 1301 in the guide mechanism 13, and can also be installed in the stepped hole 14 through the step block 1304, so that the positioning plate 1301 can be installed on the bottom surface of the movable knife 5, and then the movable knife 5 can synchronously drive the positioning plate 1301 to swing left and right. The first clamping strip 1302 and the second clamping strip 1303 can be engaged with the limiting strip 1202 in the guide mechanism 12, so that the positioning plate 1301 will make a linear reciprocating motion along the limiting strip 1202. The plurality of mounting holes 1305 can be matched with the screw holes 1306 to Seven cleaning components 1307 are installed. When the chute 8 needs to be cleaned, the knob block 13072 in the cleaning component 1307 is rotated to drive the screw 13071 to rotate, so that the pressure ring 13074 on the screw 13071 can cooperate with the side walls of the seven mounting holes 1305 to tightly clamp the cleaning plate 13073, so that the positioning plate 1301 can synchronously drive the cleaning plate 13073 to move back and forth. Then, the reciprocating cleaning plate 13073 can sweep the hair debris, so that the hair debris can be swept from the top of the guide plate 1201 to the slag discharge trough 11, achieving The purpose of cleaning hair debris is achieved, and the staff can also start the motor at the same time when cleaning hair debris, so that the movable knife 5 moving left and right can vibrate, which is convenient for cleaning more thoroughly. At the same time, the adjustment frame 4 can be pushed back and forth, so that the cleaning plate 13073, the outer tube 12083 and the guide plate 1201 can be pushed back and forth, so that the chute 8 can be cleaned more thoroughly. When the chute 8 does not need to be cleaned, the screw 13071 is loosened at this time, and the pressure ring 13074 will not cooperate with the side walls of the seven mounting holes 1305 to clamp the seven cleaning plates 13073, so that the positioning plate 13073 is not clamped. When 1301 moves back and forth, it will not cause the cleaning plate 13073 to swing significantly, thereby protecting the cleaning plate 13073. Since the inner diameter of the socket on the cleaning plate 13073 is larger than the outer diameter of the screw 13071, the screw 13071 can swing left and right and reduce the impact on the cleaning plate 13073 when not cleaning hair debris, thereby further protecting the cleaning plate 13073 and preventing fatigue damage to the cleaning plate 13073. Through the baffle 1308, it can reduce the amount of hair debris entering the chute 8 behind the guide plate 1201, thereby making it convenient for the staff to clean the chute 8.
