[0009] Further, the second transmission portion is semi-cylindrical.

[0010] Further, the trimmer further has a third position relative to the housing, and the third position is located between the first position and the second position; when the trimmer is in the third position, the switch mechanism starts the shaver body and the trimmer is separated from the swing member.

[0011] Further, the connection structure includes a first conductive connector connected to the power source and longitudinally disposed along the fixing frame for mounting the power source, a second conductive connector connected to the motor and spaced from the first conductive connector at the bottom of the fixing frame, and the second conductive connector has an elastic leg extending toward the transmission member and connected to the transmission member, which is acted on by the transmission member to overlap and connect the circuit with the first conductive connector.

[0012] Further, the trimmer has a base, and at a position of the base relative to the transmission member, there is a track suitable for the moving protrusion to slide therein, thereby causing the transmission member to rotate when the position of the trimmer changes. The track includes a first track horizontally disposed parallel to the base, in which the moving protrusion is placed when the trimmer is in the first position, a second track angularly connected to the first track, in which the moving protrusion enters from the first track when the trimmer enters the third position, and a third track longitudinally disposed parallel to the base, in which the moving protrusion slides from the second track when the trimmer enters the second position.

[0013] Further, a guiding and positioning structure is further provided between the trimmer and the shaver body to guide the trimmer to be positioned at the first position, the second position, and the third position.

[0014] Further, the guiding and positioning structure includes a guide rail longitudinally disposed on the base, a guiding protrusion disposed at a position of the housing relative to the guide rail and along which the guide rail can slide, at least two pairs of positioning protrusions are spaced apart on both side walls of the guide rail and are arranged in pairs corresponding to the third position and the second position, and recesses are formed on both sides of the guiding protrusion for the correspondingly arranged positioning protrusions to be snapped into.

[0015] Further, one end of the guide rail is further provided with a stationary groove adapted for the guiding protrusion to be inserted and corresponding to the first position of the trimmer.

[0016] Further, the distance dimension between two adjacent positioning protrusions is smaller than the length dimension of the guiding protrusion.

[0017] Further, the guide rail is elastically formed on the base. The base is provided with a mounting groove.

[0018] Further, the guiding protrusion further includes protruding portions disposed at both ends of the recessed portion and capable of passing through the channels formed by the pairwise corresponding positioning protrusions. The guiding protrusion is in an "8" shape.

[0019] The technical solution of the present invention has the following advantages:

[0020] 1. For the electric shaver provided by the present invention, a switch mechanism capable of controlling the opening and closing of the electric shaver is arranged between the shaver body and the trimmer and is linked with the trimmer. When the position of the trimmer moves, the switch mechanism also changes. The connection structure is affected by the transmission member, and the circuit of the electric shaver is connected or disconnected. The inventor combines the trimmer with the switch button, uses the switch mechanism to realize the association between the switch of the shaver body and the trimmer, and moving the trimmer can control both the trimmer and the shaver body at the same time, which is convenient to operate. Removing the switch button provided on the protruding outer shell in the prior art makes the overall appearance of the electric shaver more concise, improves the ornamental property of the appearance, and is also more conducive to waterproofing; a transmission member is arranged on the housing, and a connection structure connected to the transmission member is arranged in the housing to realize the switch of the electric shaver. The concept is ingenious and can be accurately and effectively linked with the trimmer.

[0021] 2. For the electric shaver provided by the present invention, the trimmer further has a third position between the first position and the second position. The third position is arranged between the first position and the second position, adding a state where the shaver body is started while the trimmer is not started, separating the start of the shaver body from the start of the trimmer. In this way, when only the shaver body is needed and the trimmer is not needed, the shaver body can be started alone without starting the trimmer, which is more convenient to use.

[0022] 3. For the electric shaver provided by the present invention, the transmission member transmits the position movement change of the trimmer to the moving part through the moving protrusion connected to the trimmer. The moving part rotates around the transmission hole, so that the first transmission part and the second transmission part also rotate accordingly. The second transmission part prompts the connection structure to connect the circuit of the shaver body. The structure is firm and reliable, and can effectively realize the linkage between the trimmer and the switch mechanism.

[0023] 4. The electric shaver provided by the present invention, the connection structure includes a first conductive connector and a second conductive connector. The second conductive connector has an elastic leg extending towards the first conductive connector, and the elastic leg is connected to the second transmission part. The use of the first conductive connector and the second conductive connector can effectively realize the connection and disconnection between the power supply and the motor. The structure is simple and the assembly is convenient. In addition, an elastic leg capable of connecting the two is arranged between the first conductive connector and the second metal part, and the elastic leg is connected to the second transmission part. When the transmission part rotates, the elastic leg can be acted on through the second transmission part. In this way, the connection structure is linked with the transmission part, and the cooperation between the transmission part and the elastic leg can realize the closing and opening of the circuit.

[0024] 5. The electric shaver provided by the present invention, a track is arranged on the base, and the track includes a first track, a second track and a third track corresponding to the first position, the third position and the second position respectively. The track is arranged so that the trimmer can drive the transmission part to rotate when moving, thereby realizing the connection and disconnection of the connection structure. The first track, the second track and the third track of the track can enable the transmission part to reach the target rotation state of the transmission part when the trimmer is in the first position, the second position and the third position, that is, the arc surface of the second transmission part of the transmission part is connected to the elastic leg and presses it against the first conductive connector when in the third position and the second position.

[0025] 6. The electric shaver provided by the present invention, a guiding and positioning structure capable of guiding the trimmer to be positioned at the first position, the second position and the third position is further arranged between the trimmer and the shaver body. This structure can give the user a sense of jerky rhythm, which is convenient for the user to identify whether the trimmer has reached the position of turning on the shaver body or the trimmer, and is also convenient for operating the trimmer to accurately reach the corresponding position.

[0026] 7. The electric shaver provided by the present invention, the guiding and positioning structure includes a guide rail on the base and a guiding protrusion arranged on the housing. The guide rail can slide along the guiding protrusion under the drive of the trimmer. Two pairs of positioning protrusions are arranged at intervals on both side walls of the guide rail, and recesses suitable for the corresponding positioning protrusions to be inserted into are formed on both sides of the guiding protrusion. The guide rail has elasticity. During the movement of the guide rail, it can closely adhere to both sides of the guiding protrusion and ensure that the positioning protrusion can be inserted into the recess, and can only leave the recess after receiving a certain thrust, preventing the trimmer from being easily moved, resulting in misoperation, and can also be elastically opened and closed without affecting the movement of the trimmer.

[0042] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Embodiment 1

[0044] As Figure 1 、 Figure 2 and Figure 5 shown, the electric shaver includes a shaver body 1. The shaver body 1 includes a housing 3, a razor assembly that is installed above the housing 3 and can reciprocate to cut beards, a trimmer 2 that is movably arranged on the outer side of the shaver body 1. A groove 31 is provided on the outer side of the housing 3. Part of the trimmer 2 is placed in the groove 31. A power supply 7 that provides power is arranged in the housing 3, a motor 8 that can be connected to the power supply 7 to form an electric circuit so that the shaver body 1 works, an eccentric member 10 that is connected to the motor 8 and makes the razor assembly reciprocate, a swing member 11 that reciprocates under the drive of the eccentric member 10. A swing rod 24 extending in the direction of the swing member 11 is fixed on the trimmer 2. The swing rod 24 moves up and down with the trimmer 2. When the swing rod 24 moves to be connected to the swing member 11, the trimmer 2 reciprocates with the swing member 11. A fixing frame 9 is further arranged in the housing 3, and the power supply 7 and the motor 8 are installed on the fixing frame 9.

[0045] A switch for controlling the shaver body 1 is provided for the trimmer 2. A switch mechanism that can be linked with the trimmer 2 is arranged between the shaver body 1 and the trimmer 2. The switch mechanism can connect the power supply 7 and the motor 8 to turn on or off the shaver body 1. As Figure 2 and 3 shown, the switch mechanism includes a transmission member 4 that is hinged below the housing 3 relative to the trimmer 2 and rotates with the change of the position of the trimmer 2, and a connection structure that is arranged in the housing 3 and is electrically connected to the power supply 7 and the motor 8 under the action of the transmission member 4 when the transmission member 4 rotates. A transmission hole 34 is opened in the groove 31 of the housing 3. The transmission member 4 is inserted into the transmission hole 34 and rotates with the transmission hole 34 as the origin. The part of the transmission member 4 located outside the housing 3 is connected to the trimmer 2, and the part located inside the housing 3 is connected to the connection structure. The connection structure is arranged in the housing 3 and is connected to the part of the transmission member 4 located inside the housing 3. The connection structure controls the connection and disconnection of the circuit of the shaver body 1.

[0046] In the prior art, an electric shaver has a switch button provided on its housing 3 in addition to the trimmer 2. The start and stop of the electric shaver are controlled by the switch button. The movement of the trimmer 2 provided on the housing 3 is for starting and stopping the trimmer 2, that is, the trimmer 2 in the prior art cannot control the opening and closing of the electric shaver. In the present invention, a switch mechanism capable of controlling the opening and closing of the shaver body 1 is provided between the shaver body 1 and the trimmer 2 and is linked with the trimmer 2. When the trimmer 2 moves in position, the switch mechanism also changes. Under the action of the transmission member 4, the connection structure causes the circuit of the electric shaver to be connected or disconnected. The inventor combines the trimmer 2 with the switch button and uses the switch mechanism to realize the association between the switch of the shaver body 1 and the trimmer 2. Sliding the trimmer 2 can simultaneously control the trimmer 2 and the shaver body 1, which is convenient to operate. Removing the switch button protruding from the housing in the prior art makes the overall appearance of the electric shaver more concise, improves the ornamental value of the appearance, and is also more conducive to waterproofing. The transmission member 4 is provided on the housing 3, and the connection structure connected to the transmission member 4 is provided inside the housing 3 to realize the switch of the electric shaver. The concept is ingenious and can accurately be linked with the trimmer 2.

[0047] The trimmer 2 moves on the housing 3 and has three positions relative to the housing 3, including a first position (as Figure 8 shown) and a second position (as Figure 10 shown). In the first position, the trimmer 2 is separated from the swing member 11, and the shaver body 1 and the trimmer 2 are in the off state and do not work. In the second position, the swing rod 24 is connected to the swing member 11, and the shaver body 1 and the trimmer 2 are in the on state and work normally. The trimmer 2 also has a third position relative to the housing 3 (as Figure 9 shown). The third position is located between the first position and the second position. In the third position, the shaver body 1 is on and the trimmer 2 is off, that is, the swing rod 24 is not connected to the swing member 11.

[0048] The opening process of the electric shaver is that the trimmer 2 moves from the first position to the third position and then to the second position. When the trimmer 2 moves to the third position, the switch mechanism connects the circuit and the shaver body 1 starts. When the trimmer 2 continues to move to the second position, the switch mechanism is still in the connected state, the shaver body 1 still works, and the swing rod 24 of the trimmer 2 is connected to the swing member 11 and starts.

[0049] A third position is set between the first position and the second position, adding a state where the razor body 1 is turned on while the trimmer 2 is not started, separating the start of the razor body 1 from the start of the trimmer 2, so that when only the razor body 1 needs to be used and the trimmer 2 is not needed, the razor body 1 can be started alone without starting the trimmer 2, which is more convenient to use.

[0050] As Figure 6 shown, the transmission member 4 includes a first transmission portion 43 connected to the transmission hole 34, a moving portion 42 horizontally disposed above the first transmission portion 43, a moving protrusion 41 fixed to the end of the moving portion 42 away from the first transmission portion 43 and linked with the trimmer 2, and a second transmission portion 44 disposed below the first transmission portion 43 and rotating with the moving protrusion 41 to squeeze the connection structure to electrically connect the power supply 7 and the motor 8. The second transmission portion 44 is semi-cylindrical; the first transmission portion 43 can rotate in the transmission hole 34; when the trimmer 2 is in the first position, the vertical plane of the second transmission portion 44 contacts the connection structure, and when the trimmer 2 is in the third position and the second position, the arc surface of the second transmission portion 44 contacts the connection structure; the moving portion 42 is in a water droplet shape, wherein the large head end is connected to the first transmission portion 43 and the small head end is connected to the moving protrusion 41. This structure can ensure that the moving portion 42 and the first transmission portion 43 have a large fixed area. In other embodiments, other shapes of the moving portion 42, such as an oval shape, can be selected according to actual situations and needs.

[0051] The parts of the transmission member 4 located outside the housing 3 are the moving protrusion 41 and the moving portion 42, and the parts located inside the housing 3 are the first transmission portion 43 and the second transmission portion 44.

[0052] The transmission member 4 transmits the position movement change of the trimmer 2 to the moving portion 42 through the moving protrusion 41 connected to the trimmer 2. The moving portion 42 rotates around the transmission hole 34, so that the first transmission portion 43 and the second transmission portion 44 also rotate accordingly. The second transmission portion 44 prompts the connection structure to connect the circuit of the razor body 1. The structure is firm and reliable, and can effectively realize the linkage between the trimmer 2 and the switch mechanism.

[0053] A sealing ring is provided between the transmission member 4 and the transmission hole 34, and the sealing ring is located between the first transmission portion 43 and the transmission hole 34; to prevent water from entering the razor.

[0054] As Figure 6As shown, the connection structure includes a first conductive connector 5 connected to the power supply 7 and longitudinally fixed along the fixing bracket 9 for mounting the power supply 7, and a second conductive connector 6 connected to the motor 8 and spaced from the first conductive connector 5 at the bottom of the fixing bracket 9. The second conductive connector 6 has an elastic foot 61 extending towards the transmission member 4 and being overlapped with the first conductive connector 5 under the action of the transmission member 4 to connect the circuit. The elastic foot 61 is connected to the first transmission part 43 of the transmission member 4 and includes an extension part connected to the first transmission part 43 through multiple bends and cuts and a connection part connecting the extension part and approaching the first conductive connector 5. The use of the first conductive connector 5 and the second conductive connector 6 can effectively connect and disconnect the power supply 7 and the motor 8. The structure is simple and the assembly is convenient. In addition, an elastic foot 61 capable of connecting the two is arranged between the first conductive connector 5 and the second metal part. The elastic foot 61 is connected to the second transmission part 44. When the transmission member 4 rotates, the elastic foot 61 can be acted on by the second transmission part 44. In this way, the connection structure is linked with the transmission member 4, and the cooperation between the transmission member 4 and the elastic foot 61 can realize the closing and opening of the circuit. When the trimmer 2 moves upward, the transmission member 4 rotates under the drive of the trimmer 2, and the elastic foot 61 is squeezed to the left by the first transmission part 43, and the connection structure is connected, and the shaver body 1 is started. When the trimmer 2 moves downward, the first transmission part 43 rotates to the right, canceling the extrusion of the elastic foot 61. The elastic foot 61 returns to its initial position under its own elastic action, and the connection structure is disconnected, and the shaver body 1 is turned off.

[0055] In this embodiment, the first conductive connector 5 and the second conductive connector 6 are copper parts. Of course, other conductive metal parts can also be selected.

[0056] A retaining piece 91 is arranged on the fixing bracket 9. After the elastic foot 61 contacts the retaining piece, it continues to extend to the first transmission part 43. This structure can prevent the elastic foot 61 from resetting excessively.

[0057] The first conductive connector 5 includes a first connection part 51 connected to the end of the power supply 7, a second connection part 52 for stabilizing the first connection part 51, and a third connection part 53 fixed on the fixing bracket 9. A buckle is formed on the second connection part 52. The third connection part 53 is arranged opposite to the second transmission part 44, and two first fixing holes are formed on the third connection part 53.

[0058] The second conductive connecting member 6 includes a fourth connecting portion 62 connected to the motor 8, a fifth connecting portion 63 connected to the fourth connecting portion 62, and a sixth connecting portion 64 fixed to the fixing bracket 9. The fifth connecting portion 63 causes the fourth connecting portion 62 to extend toward the motor 8. A second fixing hole for fixing the fifth connecting portion 63 is formed at one end of the fifth connecting portion 63 close to the sixth connecting portion 64. Two third fixing holes are formed in the sixth connecting portion 64, and a fixing groove 65 adapted to be connected to a hook formed on the fixing bracket 9 is provided on its edge.

[0059] The trimmer 2 includes a base 21, a pressing cover 22, and a trimming assembly 23 fixed to the tops of the base 21 and the pressing cover 22. The trimming assembly 23 can reciprocate under the drive of the swing rod 24, and the swing rod 24 is tightly fixed by the base 21 and the pressing cover 22. A pushing groove 221 for placing the thumb is formed on the lower surface of the pressing cover 22. A plurality of friction protrusions 222 for enhancing friction are provided on the pushing groove 221. Two oppositely arranged pushing holes 223 are formed in the pushing groove 221. Two pushing protrusions 251 on a pushing block 25 provided in the pressing cover 22 protrude from the pushing holes 223. The friction protrusions 222 are for increasing the friction between the human hand and the pressing cover 22, and the pushing protrusions 251 can provide a point of action for the human hand when moving the pressing cover 22 to prevent the hand from slipping.

[0060] The base 21 is further provided with a swinging hole 213 for the rod body 241 of the swing rod 24 to extend toward the swinging member 11.

[0061] As Figure 7 shown, at a position of the base 21 relative to the transmission member 4, a track 211 adapted for the moving protrusion 41 to slide therein is provided. When the position of the trimmer 2 changes during movement, the track 211 also moves accordingly, and the sliding protrusion is driven by the track 211 to slide along the track 211, that is, the base 21 drives the transmission member 4 to rotate relative to the housing 3.

[0062] The track 211 includes a first track 2111 that is horizontally arranged parallel to the base 21 and in which the moving protrusion 41 is placed when the trimmer 2 is in the first position, a second track 2112 that is angularly connected to the first track 2111 and into which the moving protrusion 41 enters from the first track 2111 when the trimmer 2 enters the third position, and a third track 2113 that is longitudinally arranged parallel to the base 21 and into which the moving protrusion 41 slides from the second track 2112 when the trimmer 2 enters the second position; when the trimmer 2 moves from the second position to the first position, the track 211 moves downward with the trimmer 2, and the moving protrusion 41 reaches the first track 2111 from the third track 2113 via the second track 2112.

[0063] When the base 21 moves upward with the trimmer 2, the track 211 can cause the transmission member 4 to rotate counterclockwise around the transmission hole 34. At this time, the vertical plane of the second transmission portion 44 faces downward, and the arc surface is connected to the second transmission portion 44 and causes the elastic support leg 61 to approach and contact the first conductive connecting member 5; when the base 21 moves downward with the trimmer 2, the track 211 can cause the transmission member 4 to rotate clockwise, and the arc surface rotates away from the elastic support leg 61, relieving the extrusion of the elastic support leg 61, and the elastic support leg 61 returns in a direction away from the first conductive connecting member 5.

[0064] The first track 2111, the second track 2112, and the third track 2113 respectively correspond to the first position, the third position, and the second position. The track 211 can guide the rotation of the transmission member 4, causing the transmission member 4 to rotate to the corresponding position, completing the startup of the electric shaver, and realizing complex operations with a simple structure.

[0065] The track 211 is provided so that when the trimmer 2 moves, it can drive the transmission member 4 to rotate, thereby realizing the connection and disconnection of the connection structure; the first track 2111, the second track 2112, and the third track 2113 of the track 211 can cause the transmission member 4 to reach the target rotation state of the transmission member 4 when the trimmer 2 is in the first position, the second position, and the third position, that is, the arc surface of the second transmission portion 44 of the transmission member 4 is connected to the elastic support leg 61 and presses it against the first conductive connecting member 5 in the third position and the second position.

[0066] A rotation groove suitable for the moving portion 42 to rotate therein is further provided on the back surface of the base 21.

[0067] A guiding and positioning structure is also provided between the trimmer 2 and the razor body 1, which can guide the trimmer 2 to be positioned at the first position, the second position and the third position. This structure can give the user a sense of jerks, facilitating the user to identify whether the trimmer 2 has reached the position to turn on the razor body 1 or the trimmer 2, and also facilitating the operation of the trimmer 2 to accurately reach the corresponding position. The guiding and positioning structure includes a guide rail 212 longitudinally arranged on the base 212, and a guiding protrusion 32 arranged at a position of the housing 3 opposite to the guide rail 212. The guide rail 212 can slide along the guiding protrusion 32 driven by the trimmer 2. Two pairs of positioning protrusions (216, 217) are arranged at intervals on both side walls of the guide rail 212, which are arranged in pairs and respectively correspond to the third position and the second position. Concave portions 321 are formed on both sides of the guiding protrusion 32 for the paired positioning protrusions (216, 217) to be snapped into. The guiding protrusion 32 is integrally formed with the housing 3.

[0068] Two pairs of first positioning protrusions 216 and second positioning protrusions 217 are arranged at intervals on both side walls of the guide rail 212, which are arranged in pairs. The first positioning protrusion 216 cooperates with the concave portion 321 to position the third position, and the second positioning protrusion 217 cooperates with the concave portion 321 to position the second position.

[0069] When the trimmer 2 moves, it drives the guide rail 212 to move upward or downward. The guiding protrusion 32 is fixed on the housing 3, and the guide rail 212 moves up and down along the guiding protrusion 32. The positioning protrusions (216, 217) are snapped into the concave portions 321 to play a positioning role. Through the cooperation between the positioning protrusions (216, 217) on the guide rail 212 and the concave portions 321 on both sides of the guiding protrusion 32, the trimmer 2 can be accurately positioned at the first position, the third position and the second position, and has an obvious sense of jerk, helping the user to clearly position to the corresponding position and avoiding operation errors.

[0070] Both side walls of the guide rail 212 have a certain elasticity. When the positioning protrusions (216, 217) move along both sides of the guiding protrusion 32, the guide rail 212 can expand outward. The base 212 is provided with an installation groove 214. Two parallel guide members 215 are fixed at one end of the installation groove 214 and extend longitudinally along the installation groove 214 to the other end to form the guide rail 212. The two guide members 215 are bent towards the side walls respectively at the other end of the installation groove 214 and are connected to the side walls. The guide rail 212 near the other end of the installation groove 214 can elastically open and close.

[0071] In the above structure, the guide rail 212 is elastic. During the movement of the guide rail 212, it can closely adhere to both sides of the guiding projection 32, and can ensure that the positioning projections (216, 217) can be snapped into the recessed portion 321 and can only leave the recessed portion 321 after receiving a certain thrust, preventing the trimmer 2 from being easily moved, resulting in misoperation. It can also open and close elastically without affecting the movement of the trimmer 2.

[0072] Above the first positioning projection 216, the guide rail 212 is provided with a stationary groove 218 adapted for the guiding projection 32 to be inserted therein for positioning the first position; when the guiding projection 32 is within the stationary groove 218, the trimmer 2 is located at the first position.

[0073] The distance between adjacent positioning projections (216, 217) is less than the length dimension of the guiding projection 32; this structure can prevent the guiding projection 32 from getting stuck between the first positioning projection 216 and the second positioning projection 217, resulting in positioning errors, the trimmer 2 not moving to the corresponding position, and the trimmer 2 being unable to start normally, causing a bad user experience.

[0074] The guiding projection 32 further includes protruding portions 322 provided at both ends of the recessed portion 321 and capable of passing through the channels formed by the pairwise corresponding positioning projections (216, 217); the guiding projection 32 is in an "8" shape; the surface of the guiding projection 32 is smooth, facilitating the movement of the guiding projection 32 within the guide rail 212.

[0075] The housing 3 is provided with a groove 31, the trimmer 2 moves within the groove 31, and a limiting structure for restricting the movement of the trimmer 2 is provided between the groove 31 and the trimmer 2; the limiting structure includes limiting grooves 33 provided on both side walls of the groove 31, and limiting projections 224 provided at positions of the trimmer 2 corresponding to the limiting grooves 33 and capable of sliding within the limiting grooves 33; the length of the limiting grooves 33 is not less than the distance length by which the trimmer 2 can move relative to the housing 3. When the trimmer 2 is at the first position, the limiting projections 224 are located at the bottom or near the bottom of the limiting grooves 33, and the trimmer 2 abuts against the bottom of the groove 31; when the trimmer 2 is at the second position, the limiting projections 224 are connected to the top ends of the limiting grooves 33.

[0076] As Figure 4 shown, the groove 31 is in a "U" shape.

[0077] The cooperation of the limiting projections 224, the limiting grooves 33 and the groove 31 restricts the movement distance of the trimmer 2 and can fix the trimmer 2 on the housing 3, preventing the trimmer 2 from easily coming off.

[0078] Embodiment 2

[0079] The trimmer 2 moves on the housing 3 and has two positions relative to the housing 3, including a first position and a second position. In the first position, the trimmer 2 is separated from the swing member 11, and the razor body 1 and the trimmer 2 are in a closed state and do not work. In the second position, the swing rod 24 is connected to the swing member 11, and the razor body 1 and the trimmer 2 are in an open state and work normally.

[0080] The track 211 includes a first track 2111 that is transversely arranged parallel to the base 21 and in which the moving protrusion 41 is placed when the trimmer 2 is in the first position, and a second track 2112 that is angularly connected to the first track 2111 and into which the moving protrusion 41 enters from the first track 2111 when the trimmer 2 enters the second position. In the first position, the moving protrusion 41 is in the first track, and in the second position, the moving protrusion is at the position of the second track 2112.

[0081] A guiding and positioning structure is further provided between the trimmer 2 and the razor body 1 to guide the trimmer 2 to be positioned at the first position and the second position. The guiding and positioning structure includes a guide rail 212 longitudinally arranged on the base 21, a guiding protrusion 32 provided at a position of the housing 3 relative to the guide rail 212. The guide rail 212 can slide along the guiding protrusion 32 driven by the trimmer 2. A pair of corresponding positioning protrusions 216 corresponding to the second position are spaced apart on both side walls of the guide rail 212, and recessed portions 321 adapted for the positioning protrusions 216 to be snapped into are formed on both sides of the guiding protrusion 32.

[0082] When the trimmer 2 moves from the first position to the second position, the guide rail 212 slides upward along the guiding protrusion 32, and the recessed portion 321 of the guiding protrusion 32 slides out of the stationary groove 218 and cooperates with the positioning protrusion 216, and the trimmer 2 is positioned at the second position.

[0083] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
