Description

Technical Field

[0001] The utility model relates to the technical field of cutters, in particular to a cutter. Background Art

[0002] Fruit knives are the most common knives in daily life. With increasing user demand, double-ended fruit knives have emerged. These knives typically include a peeling head and a slicing head, allowing them to both peel and slice food. They also include two blade covers and a button for the peeling and slicing heads. However, the buttons on commercially available double-ended fruit knives control the opening and closing of the blade covers separately. While using one blade, there's a risk of accidentally opening the cover of the unused blade by pressing the button, potentially injuring the user and reducing safety. Utility Model Content

[0003] The present application provides a knife for solving the problem that when using one blade of a double-headed fruit knife, there is a risk of accidentally touching a button to open the blade cover of the unused blade, which may easily cut the user and reduce the safety of use.

[0004] The present application provides a cutting tool, comprising a cutting tool holder, a cutting head, and a cutting cover, wherein the cutting tool holder comprises a button, the cutting heads comprise a first cutting head and a second cutting head connected to the cutting tool holder, the cutting cover comprises a first cutting cover covering the outside of the first cutting head and a second cutting cover covering the outside of the second cutting head, the button being movable relative to the cutting tool holder to enable or release the limiting engagement of the cutting cover and the cutting tool holder. The cutting tool further comprises a limiting member, the limiting member being movable relative to the button and restricting either the first cutting cover or the second cutting cover from separating from the cutting tool holder.

[0005] When the knife is in use, the first knife cover or the second knife cover releases the limiting fit with the knife holder, that is, the first knife cover or the second knife cover is separated from the knife holder, and the limiting member abuts against the button so as to limit the second knife cover or the first knife cover from releasing the limiting fit with the knife holder through the button, that is, the second knife cover or the first knife cover that has not separated from the knife holder cannot separate from the knife holder.

[0006] In this solution, when the tool is in use, the first blade head is separated from the first blade cover, that is, the first blade head is the blade head on the use side, and the second blade cover is covered on the second blade head, that is, the blade head on the unused side of the second blade head.

[0007] When the tool is in use, the limiter can limit the movement of the button, and then when the blade head (first blade head) on the used side is working, the corresponding blade cover (second blade cover) connected to the blade head on the unused side and the blade holder cannot release the limit fit, that is, at this time, the corresponding blade cover (second blade cover) connected to the blade head on the unused side cannot be pulled off from the blade head (second blade head) on the unused side, reducing the risk of the user accidentally touching the button and causing the blade head (second blade head) on the unused side to separate from the blade cover (second blade cover) it covers, thereby reducing the risk of the user being cut, which is beneficial to improving the user's safety and usage experience.

[0008] In this embodiment, the limiting member is capable of moving relative to the button along the length direction of the tool to place the tool in a first state or a second state. In the first state, the first blade cover or the second blade cover is released from the limiting engagement with the tool holder, and the limiting member abuts against the button to restrict the second blade cover or the first blade cover from releasing the limiting engagement with the tool holder through the button. In the second state, both the first blade cover and the second blade cover are limitedly engaged with the tool holder, and the limiting member releases the abutment against the button, allowing the button to move relative to the tool holder along the thickness direction of the tool.

[0009] In this solution, in the first state, the first blade cover or the second blade cover is released from the blade holder, and the limiting member abuts against the button along the thickness direction of the tool, so that the second blade cover or the first blade cover can be restricted from releasing the limiting member from the blade holder by the button. In the second state, the limiting member releases the abutment against the button along the thickness direction of the tool, allowing the button to move along the thickness direction of the tool, thereby releasing the limiting member from the blade holder. This allows the user to separate the first blade cover or the second blade cover from the blade holder according to actual needs, improving the user experience and convenience. In addition, the limiting member moves along the length direction of the tool, allowing the limiting member to utilize the space along the length direction of the tool and reduce the thickness of the tool. The button can move along the thickness direction of the tool, making it easier for the user to press.

[0010] In this embodiment, the button includes a pressing portion and an abutting portion, the abutting portion extends outward along the width direction of the tool relative to the pressing portion, and the limiting member includes a limiting portion extending outward along the width direction of the tool. During the movement of the limiting member along the length direction of the tool, the limiting member can drive the limiting portion to abut or release the abutment with the abutting portion, so that the tool is in the first state or the second state.

[0011] In this solution, in the first state, the limiting portion of the limiting member can abut against the abutting portion of the button along the thickness direction of the tool, so that the button cannot move along the thickness direction of the tool, reducing the possibility of the blade head (second blade head) on the unused side and the corresponding blade cover (second blade cover) connected to it being detached due to the movement of the button, thereby further improving the safety of users using the tool.

[0012] In the second state, the limiting portion of the limiting member can release the abutment with the abutment portion of the button along the thickness direction of the tool, so that the button can move along the thickness direction of the tool, so that the user can press the button to release the limiting cooperation between the blade head (first blade head) on the use side and the corresponding blade cover (first blade cover) connected to it, which is conducive to improving the convenience and reliability of switching the tool to the first state.

[0013] In this solution, the limiting member further includes a driving portion, which is used to abut against the knife cover. During the limiting cooperation between the knife cover and the knife seat, the limiting member can be driven to move along the length direction of the knife.

[0014] In this solution, during the process of switching from the first state to the second state, the blade cover abuts against the driving part to drive the limiting part to move along the length direction of the tool, thereby improving the convenience of switching the tool to the second state.

[0015] In this embodiment, the cutting tool further includes a first elastic member, one end of which is connected to the cutting tool holder and the other end of which is connected to the limiting portion. When the cutting tool cover and the cutting tool holder are released from the limiting engagement, the first elastic member is configured to drive the limiting member to move along the length of the cutting tool. Along the length of the cutting tool, the first elastic member and the driving portion are located at opposite ends of the limiting portion.

[0016] In this solution, in the second state, due to the contact between the driving part and the limiting part, the first elastic part is in a compressed state under the action of the tool holder and the limiting part. During the process of switching from the second state to the first state, the driving part and the limiting part are released from contact, and the first elastic part can drive the limiting part to move along the length direction of the tool so that the limiting part can contact the abutting part, reducing the risk of separation between the unused side of the tool head (second tool head) and the corresponding tool cover (second tool cover) connected to it, further improving the safety of the tool. At the same time, in the second state, the tool cover contacts the driving part so that the first elastic part can be maintained in a compressed state and the limiting part of the limiting part and the abutting part of the button are not abutted, even if the limiting part is maintained in a position separated from the abutting part so that the button can move along the thickness direction of the tool. Therefore, the setting of the driving part on the limiting part can improve the reliability and stability of the tool in the second state, thereby improving the reliability of the button being able to be pressed in the second state.

[0017] At the same time, the limiting portion is located between the driving portion and the first elastic member along the length direction of the tool. During the switching process from the first state to the second state, the driving portion can drive the limiting portion to move along the length direction of the tool to a position where the contact portion is released. During the switching process from the second state to the first state, the first elastic member can drive the limiting portion to move along the length direction of the tool to a position where the contact portion is abutted under the action of the rebound force, thereby further improving the reliability of the tool switching between the first state and the second state.

[0018] In this solution, the limiting member also includes a connecting portion and an installing portion. Along the length direction of the tool, the connecting portion connects the driving portion and the limiting portion, and the installing portion extends relative to the limiting portion in a direction away from the driving portion so that the first elastic member can be sleeved on the installing portion.

[0019] In this solution, the connecting portion is used to connect the driving portion and the limiting portion. When the driving portion abuts or releases the blade cover, the driving portion can drive the limiting portion to a position where it abuts or releases the abutment portion. At the same time, the mounting portion is used to sleeve the first elastic member, reducing the risk of the limiting member twisting during movement along the length of the tool and improving the stability of the elastic member's elastic deformation between the limiting portion and the blade holder.

[0020] In this solution, the limiting member includes a first limiting member and a second limiting member, the first limiting member and the second limiting member are located on both sides of the button along the width direction of the tool, and the driving part of the first limiting member is used to abut against the first blade cover, and the driving part of the second limiting member is used to abut against the second blade cover.

[0021] In this solution, the first and second limiting members are independent of each other. When one of the limiting portion of the first limiting member or the limiting portion of the second limiting member moves to abut against the abutment portion of the key on the same side thereof, the limiting portion of the second limiting member or the limiting portion of the first limiting member that does not move remains separated from the abutment portion of the key on the same side, i.e., does not abut. After the tool switches to the second state, the limiting portion of the first limiting member or the limiting portion of the second limiting member that moves can contact and abut against the abutment portion of the key on the same side thereof, and then the limiting portions of the first limiting member and the second limiting member are separated from the abutment portion of the key, so that the key can move in the thickness direction, thereby improving the reliability of the tool switching from the second state to the first state by pressing the key.

[0022] In this solution, the knife seat includes a cover seat, one of the cover seat and the limiting member is provided with a guide rod, and the other is provided with a guide groove, and the guide rod can slide along the guide groove.

[0023] In this solution, the cover protects the stopper, reducing the risk of damage to the stopper and thus increasing the tool's service life. Furthermore, one of the cover and the stopper is provided with a guide rod, and the other with a guide groove. The guide rod can slide along the guide groove to guide the movement of the stopper along the length of the tool, thereby increasing the accuracy with which the stopper moves to its abutment position with the abutment portion.

[0024] In this solution, the button also includes a first hook and a second hook protruding along the thickness direction of the tool, the first tool cover includes a first through hole, the second tool cover includes a second through hole, the first hook is used to engage with the first through hole, and the second hook is used to engage with the second through hole.

[0025] In this solution, the first hook engages with the first through-hole to limit the first blade cover and the blade holder, reducing the risk of the first blade cover and the blade holder being separated from each other and improving the stability and reliability of the first blade cover covering the outside of the first blade head. The second hook engages with the second through-hole to limit the second blade cover and the blade holder, reducing the risk of the second blade cover and the blade holder being separated from each other and improving the stability and reliability of the second blade cover covering the outside of the second blade head. At the same time, the first hook engages with the first through-hole and the second hook engages with the second through-hole to facilitate the user to remove or insert the first blade cover or the second blade cover relative to the blade holder, which is conducive to improving the convenience of using the knife.

[0026] In this solution, the tool includes two buttons and a second elastic member, the two buttons are arranged along the thickness direction of the tool, and the second elastic member is elastically connected between the two buttons.

[0027] In this solution, when the buttons are pressed, the two buttons move closer to each other along the thickness direction of the tool, compressing the second elastic member. When the buttons are released, the two buttons move away from each other due to the rebound force of the second elastic member and extend out of the cover, making it easier for the user to press them, thereby improving the convenience of switching the tool from the second state to the first state.

[0070] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0071] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0072] In a specific embodiment, the present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0073] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0074] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0075] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0076] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0077] The embodiment of the present application provides a tool, such as Figure 1 and Figure 2 As shown, the tool includes a tool holder 1, a tool head 2 and a tool cover 3. The tool holder 1 includes a button 12. The tool head 2 includes a first tool head 21 and a second tool head 22 connected to the tool holder 1. The tool cover 3 includes a first tool cover 31 covering the outside of the first tool head 21 and a second tool cover 32 covering the outside of the second tool head 22. The button 12 can move relative to the tool holder 1 so that the tool cover 3 and the tool holder 1 can be limited or released. The tool also includes a limiting member 11 movably connected to the tool holder 1. The limiting member 11 can move relative to the button 12 and limit one of the first tool cover 31 or the second tool cover 32 from being separated from the tool holder 1. Figure 3-Figure 5 As shown, when the knife is in use, the first knife cover 31 or the second knife cover 32 is released from the knife seat 1, that is, the first knife cover 31 or the second knife cover 32 is separated from the knife seat 1, and the limiting member 11 abuts against the button 12, so that the second knife cover 32 or the first knife cover 31 is restricted from releasing the limiting cooperation with the knife seat 1 through the button 12, that is, the second knife cover 32 or the first knife cover 31 that has not been separated from the knife seat 1 cannot be separated from the knife seat 1. Specifically, when the knife is in use, that is, the first knife cover 31 or the second knife cover 32 is released from the knife seat 1, so that the first knife head 21 is separated from the first knife cover 31 or the second knife head 22 is separated from the second knife cover 32, thereby exposing the first knife head 21 or the second knife head 22 to facilitate processing of food.

[0078] Therefore, when the tool is in use, the limiter 11 can limit the movement of the button 12, and then when the blade head (first blade head 21) on the used side is working, the corresponding blade cover (second blade cover 32) connected to the blade head on the unused side cannot be released from the blade holder 1. That is, at this time, the corresponding blade cover (second blade cover 32) connected to the blade head on the unused side cannot be pulled out from the blade head (second blade head 22) on the unused side, reducing the risk of the user accidentally touching the button 12 and causing the blade head (second blade head 22) on the unused side to separate from the blade cover (second blade cover 32) it covers, thereby reducing the risk of the user being cut, which is beneficial to improving the user's safety and usage experience.

[0079] It should be noted that the button 12 of the tool can be structured to move along the thickness direction Z or width direction Y of the tool, as long as the first blade cover 31 or the second blade cover 32 can be removed by pressing the button 12. The limiter 11 can be structured to move along the length direction X or width direction Y of the tool, as long as the limiter 11 can move to abut or release the button 12.

[0080] like Figure 1-Figure 5 As shown, the limiting member 11 can move relative to the button 12 along the length direction X of the tool to put the tool into a first state or a second state. The first state is the use state of the tool, and the second state is the unuse state of the tool.

[0081] In the first state, the first blade cover 31 or the second blade cover 32 is released from the limiting engagement with the blade holder 1, and the limiting member 11 abuts against the button 12, so that the second blade cover 32 or the first blade cover 31 is restricted from being released from the limiting engagement with the blade holder 1 by the button 12. In the second state, both the first blade cover 31 and the second blade cover 32 are limited to the blade holder 1, and the limiting member 11 abuts against the button 12, so that the button 12 can move relative to the blade holder 1 in the thickness direction Z of the blade.

[0082] The following description assumes that when the tool is in the first state, the first blade head 21 is separated from the first blade cover 31, that is, the first blade head 21 is the blade head 2 on the use side, and the second blade cover 32 is covered on the second blade head 22, that is, the blade head 2 on the unused side of the second blade head 22.

[0083] like Figure 1 As shown, in the second state, the first blade cover 31 and the second blade cover 32 are both limitedly engaged with the blade holder 1 , and the limiting member 11 is released from contact with the button 12 , so that the button 12 can move relative to the blade holder 1 .

[0084] The second state is the non-use state of the tool, that is, the first tool cover 31 and the second tool cover 32 are limitedly matched with the tool holder 1 so that the first tool cover 31 covers the outer side of the first tool head 21 and the second tool cover 32 covers the outer side of the second tool head 22.

[0085] When needed from Figure 1 The second state shown switches to Figure 3 and Figure 5 In the first state shown, the button 12 is pressed to move the button 12 along the knife holder 1, so that the first knife cover 31 and the first knife head 21 are released from the limited fit, and the first knife cover 31 and the first knife head 21 can be separated, so that the first knife head 21 is exposed, and the user can use the first knife head 21 to process food. At the same time, in the process of pressing the button 12 to separate the first knife cover 31 and the first knife head 21, the limiting member 11 can move so that the limiting member 11 can abut against the button 12, thereby limiting the movement of the button 12, that is, the button 12 cannot be pressed at this time, so that the knife is switched to the position shown in FIG. Figure 3 At the same time, in the first state shown in Figure 1 In the second state shown, the limiting member 11 can release the contact with the button 12 along the tool, so that the button 12 can be pressed again, so that the tool switches to the first state.

[0086] Similarly, if Figure 4 As shown, when the second blade head 22 is the blade head 2 on the used side and the first blade head 21 is the blade head 2 on the unused side (the first blade cover 31 is limited in engagement with the blade holder 1, and the second blade cover 32 is released from the blade holder 1, exposing the second blade head 22), the movement process of the tool when switching to the first state is the same as the movement process of the switching described above, and will not be repeated here.

[0087] In addition, the first blade head 21 can be a peeling blade head 2, and the second blade head 22 can be a slitting blade head 2, or the first blade head 21 can be a slitting blade head 2, and the second blade head 22 can be a peeling blade head 2. The first blade head 21 and the second blade head 22 can also be blades or tools with other functions. This application does not limit the functions and types of the first blade head 21 and the second blade head 22, as long as the functions of the first blade head 21 and the second blade head 22 are different.

[0088] In the first state, the first blade cover 31 or the second blade cover 32 is released from the restricted engagement with the blade holder 1, and the limiting member 11 abuts against the button 12 along the thickness direction Z of the tool, so that the second blade cover 32 or the first blade cover 31 is restricted from being released from the restricted engagement with the blade holder 1 by the button 12. In the second state, the limiting member 11 is released from the abutment against the button 12 along the thickness direction Z of the tool, so that the button 12 can move along the thickness direction Z of the tool, thereby releasing the restricted engagement between the blade cover 3 and the blade holder 1. This allows the user to separate the first blade cover 31 or the second blade cover 32 from the blade holder 1 according to actual needs, thereby improving the user experience and convenience.

[0089] In addition, the limiter 11 moves along the length direction X of the tool, so that the limiter 11 can use the space in the length direction X of the tool to reduce the thickness of the tool. The button 12 can move along the thickness direction Z of the tool, which is convenient for the user to press.

[0090] In one possible implementation, Figure 6 and Figure 7 As shown, the button 12 includes a pressing portion 121 and an abutting portion 122, and the abutting portion 122 extends outward along the width direction Y of the tool relative to the pressing portion 121. The limiting member 11 includes a limiting portion 111 extending outward along the width direction Y of the tool. During the movement of the limiting member 11 along the length direction X of the tool, it can drive the limiting portion 111 to abut or release the abutment with the abutting portion 122, so that the tool is in the first state or the second state.

[0091] In the first state, the first blade cover 31 or the second blade cover 32 is released from the limiting engagement with the blade holder 1, and the limiting portion 111 abuts against the abutting portion 122 to limit the movement of the button 12 relative to the blade holder 1; in the second state, the first blade cover 31 and the second blade cover 32 are both limited in engagement with the blade holder 1, and the limiting portion 111 and the abutting portion 122 are released from abutment to allow the button 12 to move relative to the blade holder 1.

[0092] In this embodiment, in the first state, the limiting portion 111 of the limiting member 11 can abut against the abutting portion 122 of the button 12 along the thickness direction Z of the tool, thereby preventing the button 12 from moving along the thickness direction Z of the tool. This reduces the possibility of the unused blade head (second blade head 22) and its corresponding blade cover (second blade cover 32) being separated due to the movement of the button 12, further improving the safety of the user when using the tool. At the same time, the abutting portion 122 extends outwardly relative to the pressing portion 121 along the width direction Y of the tool. The limiting member 11 includes the limiting portion 111 extending outwardly along the width direction Y of the tool, allowing the abutting portion 122 and the limiting portion 111 to avoid the pressing portion 121, reducing the risk of interference, facilitating the pressing of the button 12, and facilitating the reliability of the abutment between the abutting portion 122 and the limiting portion 111 along the thickness direction Z of the tool.

[0093] In the second state, the limiting portion 111 of the limiting member 11 can release the contact with the contact portion 122 of the button 12 along the thickness direction Z of the tool, so that the button 12 can move along the thickness direction Z of the tool, so that the user can press the button 12, so that the blade head (first blade head 21) on the use side can release the limiting cooperation with the corresponding blade cover (first blade cover 31) connected to it, which is conducive to improving the convenience and reliability of switching the tool to the first state.

[0094] In other embodiments, the limiting member 11 may also be a structure capable of moving along the width direction Y of the tool. In this case, the abutting portion 122 may be a structure extending outward along the length direction X of the tool.

[0095] In one possible implementation, Figure 6 and Figure 7As shown, the limit member 11 includes a first limit member 112 and a second limit member 113. The first limit member 112 and the second limit member 113 are located on both sides of the button 12 along the width direction Y of the tool. Abutment portions 122 are provided on both sides of the pressing portion 121 along the width direction Y. The first limit member 112 abuts against the first blade cover 31, and the second limit member 113 abuts against the second blade cover 32. When the tool switches from the first state to the second state, the first blade cover 31 drives the first limit member 112 to move along the length direction X of the tool, or the second blade cover 32 drives the second limit member 113 to move along the length direction X of the tool.

[0096] In the first state, one of the limiting portion 111 of the first limiting member 112 and the limiting portion 111 of the second limiting member 113 abuts against the abutting portion 122, while the other is released from the abutting portion 122. In the second state, both the limiting portion 111 of the first limiting member 112 and the limiting portion 111 of the second limiting member 113 are released from the abutting portion 122. Specifically, the first limiting member 112 and the second limiting member 113 have the same structure and are symmetrically arranged relative to the center of the key 12. In this embodiment, the first limiting member 112 can abut against the blade cover on the used side (the first blade cover 31), and the second limiting member 113 can abut against the blade cover on the unused side (the second blade cover 32).

[0097] When needed from Figure 1 The second state shown switches to Figure 3 and Figure 5 In the first state shown, during the process of separation of the first blade cover 31 and the first blade head 21, the first limiting member 112 can move along the length direction X of the tool, so that the limiting portion 111 of the first limiting member 112 can abut against the abutting portion 122 on the button 12 located on the same side thereof along the thickness direction Z of the tool, thereby limiting the movement of the button 12 along the thickness direction Z of the tool, that is, the button 12 cannot be pressed at this time, thereby switching the tool to the first state.

[0098] When needed from Figure 3 and Figure 5 The first state shown switches to Figure 1 In the second state shown, during the process of the first blade cover 31 abutting against the first limiter 112, the first limiter 112 can be driven to move along the length direction X of the tool, so that the limiting portion 111 of the first limiter 112 can be released from the abutment portion 122 of the button 12 located on the same side thereof along the thickness direction Z of the tool, and then the button 12 can move along the thickness direction Z of the tool, so that the first blade cover 31 can be limited and matched with the blade holder 1, even if the first blade cover 31 covers the outside of the first blade head 21, so that the tool is switched to the second state.

[0099] In addition, during the process of switching the tool between the first state and the second state, since the second blade cover 32 is always limited in cooperation with the blade holder 1, the second limiting member 113 is still in a stationary state, that is, the limiting portion 111 of the second limiting member 113 is still not in contact with the abutment portion 122 on the button 12 on the same side thereof, so that when the first blade cover 31 covers the outer side of the first blade head 21, the button 12 can be pressed along the thickness direction Z of the tool, making it convenient for the tool to switch from the second state to the first state by pressing the button 12.

[0100] Therefore, the first limiting member 112 and the second limiting member 113 are independent of each other. When one of the limiting portion 111 of the first limiting member 112 or the limiting portion 111 of the second limiting member 113 moves to abut against the abutment portion 122 of the button 12 located on the same side thereof, the limiting portion 111 of the second limiting member 113 that has not moved or the limiting portion 111 of the first limiting member 112 is still separated from the abutment portion 122 of the button 12 located on the same side, that is, not abutting. When the tool switches to the second state, the moving limiting portion 111 of the first limiting member 112 or the limiting portion 111 of the second limiting member 113 can contact and abut the abutment portion 122 of the button 12 located on the same side thereof, so that the limiting portion 111 of the first limiting member 112 and the limiting portion 111 of the second limiting member 113 are separated from the abutment portion 122 of the button 12, so that the button 12 can move along the thickness direction Z, thereby improving the reliability of the tool switching from the second state to the first state by pressing the button 12.

[0101] In one possible implementation, Figure 6 and Figure 7 As shown, the limiting member 11 also includes a driving portion 114, which is used to abut against the knife cover 3. During the limiting cooperation between the knife cover 3 and the knife seat 1, the limiting member 11 can be driven to move along the length direction X of the tool. In the process of switching from the first state to the second state, the knife cover 3 abuts against the driving portion 114 to drive the limiting portion 111 to move along the length direction of the tool, thereby improving the convenience of switching the tool to the second state.

[0102] In one possible implementation, Figure 7 As shown, the tool also includes two first elastic members 4, one end of the first elastic member 4 is connected to the tool holder 1, and the other end is connected to the limiting portion 111. In the process of releasing the limiting cooperation between the tool cover 3 and the tool holder 1, the first elastic member 4 is used to drive the limiting member 11 to move along the length direction X of the tool, so that the limiting portion 111 and the abutting portion 122 can abut along the thickness direction Z of the tool.

[0103] In this embodiment, in the second state, due to the abutment between the driving portion 114 and the limiting member 11, the first elastic member 4 is in a compressed state under the action of the blade holder 1 and the limiting portion 111. When the blade head (first blade head 21) on the used side is separated from the corresponding blade cover (first blade cover 31) connected thereto, the first elastic member 4 can drive the limiting portion 111 of the first limiting member 112 or the limiting portion 111 of the second limiting member 113 to move along the longitudinal direction X of the tool under the action of the rebound force, so that the limiting portion 111 of the first limiting member 112 or the limiting portion 111 of the second limiting member 113 can abut against the abutment portion 122 of the button 12 located on the same side thereof, further improving the reliability of the limiting portion 111 of the limiting member 11 moving to the abutment position with the abutment portion 122 of the button 12, further reducing the risk of separation of the blade head (second blade head 22) on the unused side from the corresponding blade cover (second blade cover 32), and further improving the safety of the tool.

[0104] Furthermore, in the second state, the blade cover 3 abuts the driving portion 114, so that the first elastic member 4 can be maintained in a compressed state, thereby preventing the limiting portion 111 of the limiting member 11 from abutting the abutting portion 122 of the button 12, that is, the limiting portion 111 is maintained in a position separated from the abutting portion 122, so that the button 12 can move along the tool's thickness direction Z. Therefore, the provision of the driving portion 114 on the limiting member 11 can improve the reliability and stability of the tool being maintained in the second state, thereby improving the reliability of the button 12 being able to be pressed in the second state.

[0105] In one possible implementation, Figure 6 and Figure 8 As shown, along the longitudinal direction X of the tool, the first elastic member 4 and the driving portion 114 are located at both ends of the limiting portion 111, that is, along the longitudinal direction X of the tool, the limiting portion 111 is located between the driving portion 114 and the first elastic member 4. During the switching process from the first state to the second state, the driving portion 114 can drive the limiting portion 111 to move along the longitudinal direction X of the tool to a position where it is released from the abutment portion 122. During the switching process from the second state to the first state, the first elastic member 4, under the action of the rebound force, can drive the limiting portion 111 to move along the longitudinal direction X of the tool to a position where it abuts the abutment portion 122, further improving the reliability of the tool switching between the first and second states. The tool can be restored to the position where the limiting portion and the abutment portion abut without manual actuation, thereby further reducing the risk of the knife cover being separated from the knife seat due to accidental human touch of the button, further improving the safety of the tool.

[0106] In one possible implementation, Figure 6 As shown, along the width direction Y of the tool, the driving portions 114 of the two limiting members 11 both extend in a direction away from the pressing portion 121 .

[0107] In this embodiment, the driving portion 114 extends along the width direction Y of the tool to increase the contact area between the driving portion 114 and the blade cover 3. This improves the reliability and stability of the blade cover 3 contacting and driving the driving portion 114 when the blade cover 3 is closed on the outside of the tool head 2. In addition, along the width direction Y of the tool, the driving portions 114 of the two limiting members 11 extend in a direction away from the pressing portion 121, so that each driving portion 114 can avoid the button 12. This reduces the possibility of interference between the driving portion 114 and the button 12 during movement of the driving portion 114 along the length direction X of the tool, thereby improving the reliability and smoothness of the movement of the limiting member 11 along the length direction X of the tool.

[0108] In one possible implementation, Figure 9 As shown, the limiting member 11 also includes a connecting portion 115 and a mounting portion 116. Along the length direction X of the tool, the connecting portion 115 connects the driving portion 114 and the limiting portion 111, and the mounting portion 116 extends relative to the limiting portion 111 in a direction away from the driving portion 114 so that the first elastic member 4 can be sleeved on the mounting portion 116.

[0109] In this embodiment, the connecting portion 115 is used to connect the driving portion 114 and the limiting portion 111. When the driving portion 114 abuts or releases the blade cover 3, the driving portion 114 can drive the limiting portion 111 to a position where it abuts or releases the abutment portion 122. At the same time, the mounting portion 116 is used to sleeve the first elastic member 4, reducing the risk of twisting of the limiting member 11 during movement along the longitudinal direction X of the tool and improving the stability of the elastic member's elastic deformation between the limiting portion 111 and the blade holder 1.

[0110] The connecting portion 115 and the mounting portion 116 may be an integrally formed rod-shaped structure.

[0111] In one possible implementation, Figure 8 As shown, the knife holder 1 includes a cover seat 13 , one of the cover seat 13 and the limiting member 11 is provided with a guide rod 131 , and the other is provided with a guide groove 117 , and the guide rod 131 can slide along the guide groove 117 .

[0112] In this embodiment, the cover 13 protects the stopper 11, reducing the risk of damage to the stopper 11 and thereby increasing the tool's service life. Furthermore, one of the cover 13 and the stopper 11 is provided with a guide rod 131, while the other is provided with a guide slot 117. The guide rod 131 can slide along the guide slot 117 to guide the movement of the stopper 11 along the tool's longitudinal direction X, thereby facilitating improved accuracy in the movement of the stopper 111 to its contact position with the abutment 122.

[0113] The cover seat 13 may be provided with an escape portion 134 , and along the thickness direction Z of the tool, the pressing portion 121 may extend out of the cover seat 13 through the escape portion 134 , making it easier for the user to press.

[0114] In one possible implementation, Figure 1 and Figure 2 As shown, the button 12 also includes a first hook 123 and a second hook 124 protruding along the thickness direction Z of the tool, the first tool cover 31 includes a first through hole 311, and the second tool cover 32 includes a second through hole 321. The first hook 123 is used to engage with the first through hole 311, and the second hook 124 is used to engage with the second through hole 321.

[0115] like Figure 1 As shown, the first hook 123 engages with the first through hole 311 to limit the first blade cover 31 and the blade holder 1, reducing the risk of the first blade cover 31 and the blade holder 1 being separated from each other, and improving the stability and reliability of the first blade cover 31 covering the outer side of the first blade head 21. The second hook 124 engages with the second through hole 321 to limit the second blade cover 32 and the blade holder 1, reducing the risk of the second blade cover 32 and the blade holder 1 being separated from each other, and improving the stability and reliability of the second blade cover 32 covering the outer side of the second blade head 22. At the same time, the first hook 123 engages with the first through hole 311, and the second hook 124 engages with the second through hole 321, so that the user can remove or insert the first blade cover 31 or the second blade cover 32 relative to the blade holder 1, which is conducive to improving the convenience of using the knife.

[0116] Among them, such as Figure 2 As shown, the cover seat 13 can also be provided with a third through hole 132 and a fourth through hole 133, the first through hole 311 is connected to the third through hole 132, the second through hole 321 is connected to the fourth through hole 133, the first hook 123 extends through the third through hole 132 and is engaged with the first through hole 311, and the second hook 124 extends through the fourth through hole 133 and is engaged with the second through hole 321.

[0117] In one possible implementation, Figure 2 As shown, the tool includes two buttons 12 and a second elastic member 5 . The two buttons 12 are arranged along the thickness direction Z of the tool, and the second elastic member 5 is elastically connected between the two buttons 12 .

[0118] In this embodiment, when pressing the buttons 12, the two buttons 12 move closer to each other along the thickness direction Z of the tool, thereby compressing the second elastic member 5. When the buttons 12 are released, the two buttons 12 can move away from each other under the action of the rebound force of the second elastic member 5 and extend out of the cover 13, thereby making it easier for the user to press them, thereby improving the convenience of switching the tool from the second state to the first state.

[0119] In addition, if Figure 2 As shown, the tool includes two cover seats 13, which can be enclosed and form a cavity so that the above-mentioned limiter 11 and button 12 are both installed in the cavity. The tool can also include a mounting seat 6, which can be connected to the first cutting head 21 by interference fit. The mounting seat 6 can be connected to the cover seat 13 by snap fastening and welding, so that the first cutting head 21 is connected to the cover seat 13 via the mounting seat 6. At the same time, a fixing plate 7 is also provided between the two buttons 12. The fixing plate 7 and the second cutting head 22 can be an integrally formed structure. The fixing plate 7 and the cover seat 13 are connected by limiting columns and limiting holes, so that the second cutting head 22 is connected to the cover seat 13 via the fixing plate 7.

Any changes or substitutions within the technical scope disclosed in the embodiments of the present application shall be included in the scope of protection of the embodiments of the present application. Therefore, the scope of protection of the embodiments of the present application shall be based on the scope of protection of the claims.
