Description

Technical Field

[0001] The utility model belongs to the technical field of cutting tools, and in particular relates to a tool with dual use states. Background Art

[0002] A knife is a daily necessity for cutting objects. Knives are divided into cutting knives, bayonets, etc. Among them, since the blade of the cutter is arranged at the front end of the handle, when in use, the user can hold the handle to operate the blade to move back and forth to cut objects, which is convenient for cutting objects; while the blade of the bayonet is arranged at the lower end of the handle. When in use, the user can grasp the handle to operate the tip of the front end of the blade to pierce objects, which is convenient for piercing objects.

[0003] However, the existing knives have only one usage state, that is, the cutter is only suitable for cutting objects, and the bayonet is only suitable for piercing objects. The two cannot coexist in one knife. This requires users to equip two knives of different types to meet the cutting and piercing requirements, which increases the purchase cost and is inconvenient to carry and store the knives. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a dual-use knife, which can be used as a cutter for cutting objects and as a bayonet for piercing objects. One knife can simultaneously meet the user's requirements for cutting and piercing objects.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a dual-use knife, including a handle and a blade, the above-mentioned handle includes a front handle body and a rear handle body, the blade is arranged at the front end of the front handle body, the rear end of the front handle body is rotatably connected to the rear handle body, and the front handle body can be rotated relative to the rear handle body to a cutting knife state and a bayonet state.

[0006] In the above scheme, by separating the knife handle into a front handle body and a rear handle body, the blade is arranged at the front end of the front handle body, and the front handle body can be rotated relative to the rear handle body to a cutter state and a bayonet state. When in use, when it is necessary to cut an object, the front handle body can be rotated to the cutter state, so that it can be conveniently used for cutting objects; and when it is necessary to pierce an object, the front handle body can be rotated to the bayonet state, so that it can be conveniently used for piercing objects. Thus, one knife can meet the requirements of cutting and piercing objects at the same time, so that users do not need to be equipped with two different types of knives, saving purchase costs and convenient to carry and store.

[0007] Furthermore, the knife handle further comprises a middle handle body rotatably connected to the front handle body, a slide post is provided on the outside of the middle handle body, an arc-shaped slide groove is provided on the inside of the rear handle body, the slide post is slidably matched in the arc-shaped slide groove, and the rotation of the front handle body drives the slide post of the middle handle body to slide along the arc-shaped slide groove, and when the slide post slides to the front end position of the arc-shaped slide groove, the front handle body rotates to the cutting knife state, at which time the front end of the arc-shaped slide groove will block the slide post from sliding forward, thereby positioning the front handle body in the cutting knife state, and preventing the front handle body from rotating excessively forward. When the slide post slides to the rear end position of the arc-shaped slide groove, the front handle body rotates to the bayonet state, at which time the rear end of the arc-shaped slide groove will block the slide post from sliding backward, thereby positioning the front handle body in the bayonet state, and preventing the front handle body from rotating excessively backward.

[0008] Furthermore, a first rotating shaft is provided on the outer side of the front handle body, and a rotating hole is opened on the middle handle body corresponding to the position of the first rotating shaft. The first rotating shaft is placed in the rotating hole so that the first rotating shaft of the front handle body can rotate with the rotating hole of the middle handle body, thereby realizing the rotational connection between the middle handle body and the front handle body.

[0009] Furthermore, the above-mentioned knife also includes a locking mechanism that can lock the front handle body in the cutting knife state and the bayonet state to ensure the structural stability of the knife in the cutting knife state and the bayonet state, making it more convenient and safe to use.

[0010] Furthermore, a guide block is provided on the outer side of the front handle body corresponding to the position of the first rotating shaft, a first sliding groove is provided on the inner side of the first rotating shaft, the first rotating shaft is mounted on the outer side of the guide block through the first sliding groove, and can slide relative to the guide block, the locking mechanism includes a protrusion arranged on the outer side of the first rotating shaft, a third sliding groove opened on the side wall of the rotating hole, and a first elastic member, the protrusion is placed in the third sliding groove, and the first rotating shaft will drive the protrusion to slide along the third sliding groove when it rotates, and in the absence of external force, the first elastic member will push the first rotating shaft to slide outward relative to the guide block through its elastic force, and the bottom position of the third sliding groove is also provided with a first locking groove and a second locking groove. When the front handle body rotates to the cutting knife state, the first elastic member will push the projection of the first rotating shaft to cooperate with the first locking groove. At this time, under the cooperation of the projection and the first locking groove, the first rotating shaft of the front handle body cannot rotate along the rotating hole of the middle handle body, that is, the front handle body and the middle handle body remain relatively fixed, and because the middle handle body and the front handle body and the rear handle body form a linkage structure, when the front handle body cannot rotate relative to the middle handle body, the front handle body cannot rotate relative to the rear handle body. Therefore, the front handle body, the middle handle body and the rear handle body remain relatively fixed at this time, thereby locking the front handle body in the cutting knife state, ensuring the structural stability of the tool in the cutting knife state. When the front handle body rotates to the bayonet state, the first elastic member pushes the projection of the first rotating shaft to cooperate with the second locking groove, so that the front handle body can be locked in the bayonet state, ensuring the structural stability of the tool in the bayonet state. In addition, when the tool is locked in the cutting knife state or the bayonet state, the user can press the first rotating shaft to make the projection disengage from the locking groove, so as to release the lock, and the unlocking operation is convenient.

[0011] Furthermore, the above-mentioned first elastic member is a first spring arranged in the first slide groove, and a spring groove is opened on the outside of the guide block. The first spring is installed in the spring groove, which can improve the installation stability of the first spring. The two ends of the first spring are respectively against the bottom of the first slide groove and the bottom of the spring groove. In the absence of external force, the first spring will push the first rotating shaft to slide outward relative to the guide block through its elastic force.

[0012] Further, the middle handle body includes a left middle handle piece and a right middle handle piece that are relatively arranged, and the rear handle body includes a left rear handle piece and a right rear handle piece that are relatively arranged, and the left middle handle piece and the right middle handle piece are respectively located at the left and right outer sides of the front handle body, the left rear handle piece is located at the outer side of the left middle handle piece, and the right rear handle piece is located at the outer side of the right middle handle piece, and the first rotating shaft has two and is respectively arranged at the left and right outer sides of the front handle body, and the arc-shaped sliding groove has two and is respectively arranged at the inner side of the two rear handle pieces, and the two middle handle pieces are provided with rotating holes and sliding columns, and the rear end of the front handle body is rotatably connected with the two rear handle pieces through the second rotating shaft. In this way, the rotation and locking of the front handle body can be made more stable, and the front handle body, the middle handle body and the rear handle body are more stably linked to each other.

[0013] Furthermore, the front handle body comprises a left front handle piece and a right front handle piece which are arranged opposite to each other, the rear end of the blade is hinged to the front end position between the two front handle pieces, and the blade can be rotated to open and folded relative to the two front handle pieces. When the knife is not in use, the blade can be rotated and folded to the position between the two front handle pieces to protect the blade, reduce the size of the knife, and facilitate the carrying and storage of the knife.

[0014] Furthermore, the above-mentioned tool also includes a locking mechanism for locking the blade in the open state, the locking mechanism includes a locking block, a push rod connected to the left end face of the locking block, a button, and a second spring, the left end of the push rod passes through the left front handle piece, the button is connected to the left end of the push rod, and the button is located at the outer side of the left front handle piece, the tail end of the blade is provided with a bayonet that cooperates with the locking block, the inner side of the right front handle piece is provided with a second slide groove, the locking block is placed in the second slide groove, and can slide left and right relative to the second slide groove, when in use, when the blade is rotated to the open state, the second spring will push the locking block to slide leftward along the second slide groove through its own elastic force and cooperate with the bayonet, at this time, the blade cannot rotate under the action of the bayonet and the left end of the locking block, so that the blade can be locked in the open state. After pressing the button to push the locking block to slide rightward along the second slide groove and disengage from the bayonet, the locking of the blade in the open state can be released, so that the blade can be rotated and folded.

[0015] Furthermore, a positioning column is provided at the front end position between the left front handle piece and the right front handle piece. When the blade is rotated to the open state, the rear end surface of the blade abuts against the positioning column. At this time, the positioning column can prevent the blade from excessively rotating in the opening direction, and can also position the blade in the open state, so that the left end of the locking block can be better aligned with the bayonet position and cooperate more easily.

[0016] The knife of the utility model can be converted into a cutting knife state and a bayonet state for use, so that one knife can meet the requirements of cutting and piercing objects, so that the user does not need to be equipped with two knives of different types, thus saving purchase costs and being convenient to carry and store.

[0028] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0029] Embodiment 1

[0030] like Figure 1-3 As shown, this embodiment provides a knife with dual use states, that is, the knife can be used in a cutting state and a bayonet state, and includes a handle 1 and a blade 2. The handle 1 includes a front handle body 11 and a rear handle body 12. The blade 2 is arranged at the front end of the front handle body 11, and the rear end of the front handle body 11 is rotatably connected to the rear handle body 12. The front handle body 11 can be rotated relative to the rear handle body 12 to a cutting state and a bayonet state.

[0031] like Figure 4 As shown, the knife handle 1 further comprises a middle handle body 13 rotatably connected to the front handle body 11, wherein the middle handle body 13 comprises a left middle handle piece 131 and a right middle handle piece 132 arranged oppositely, and the rear handle body 12 comprises a left rear handle piece 121 and a right rear handle piece 122 arranged oppositely, the left middle handle piece 131 and the right middle handle piece 132 are respectively located at the left and right outer positions of the front handle body 11, the left rear handle piece 121 is located at the outer position of the left middle handle piece 131, and the right rear handle piece 122 is located at the outer position of the right middle handle piece 132. The rear end of the front handle body 11 is provided with a second rotating shaft 8, and the two rear handle pieces are respectively penetrated with connecting pins 81, and the two ends of the second rotating shaft 8 are respectively connected with the two connecting pins 81, so that the front handle body 11 can rotate relative to the two rear handle pieces through its second rotating shaft 8.

[0032] The first rotating shaft 3 is respectively arranged at the left and right outer positions of the above-mentioned front handle body 11, and the two middle handle pieces are respectively opened with rotating holes 130 corresponding to the positions of the first rotating shaft 3. The first rotating shaft 3 is placed in the rotating holes 130, so that the two first rotating shafts 3 of the front handle body 11 can rotate with the rotating holes 130 of the two middle handle pieces, thereby realizing the rotational connection between the middle handle body 12 and the front handle body 11.

[0033] like Figure 4 , 5As shown, the left middle handle piece 131 and the right middle handle piece 132 are provided with slide posts 133 at the outer positions of the rear ends, and the inner sides of the two rear handle pieces are provided with arc-shaped slide grooves 120, respectively. The slide posts 133 slide in the arc-shaped slide grooves 120, and the rotation of the front handle body 11 will drive the slide posts 133 of the two middle handle pieces to slide along the arc-shaped slide grooves 120. Figure 1 As shown in FIG. 1 , when the slide post 133 slides to the front end of the arc-shaped slot 120, the front handle body 11 rotates to the cutting state. At this time, the front end of the arc-shaped slot 120 blocks the slide post 133 from sliding forward, thereby positioning the front handle body 11 in the cutting state and preventing the front handle body 11 from rotating excessively forward. Figure 3 As shown, when the slide post 133 slides to the rear end position of the arc-shaped slide groove 120, the front handle body 11 rotates to the bayonet state. At this time, the rear end of the arc-shaped slide groove 120 will block the slide post 133 from continuing to slide backward, thereby positioning the front handle body 11 in the bayonet state to prevent the front handle body 11 from rotating excessively backward.

[0034] The knife of this embodiment can be switched between the cutting knife and the bayonet knife at will. Figure 1 As shown, when it is necessary to cut an object, the front handle body 11 can be rotated to a cutting knife state, so that it can be conveniently used for cutting objects; and as shown in FIG. Figure 3 As shown, when it is necessary to pierce an object, the front handle body 11 can be rotated to the bayonet state, so that it can be conveniently used to pierce the object. A knife can meet the requirements of cutting and piercing an object at the same time, so that the user does not need to be equipped with two different types of knives, saving purchase costs and being convenient to carry and store.

[0035] Embodiment 2

[0036] This embodiment is a further improvement on the tool structure of the first embodiment, and the improvement is that: Figure 4 As shown, the above-mentioned knife also includes a locking mechanism that can lock the front handle body 11 in the cutting state and the bayonet state to ensure the structural stability of the knife in the cutting state and the bayonet state, making it more convenient and safe to use.

[0037] Specifically, a guide block 4 is provided on the outer side of the front handle body 11 corresponding to the position of the first rotating shaft 3, and a first sliding groove 30 is provided on the inner side of the first rotating shaft 3. The first rotating shaft 3 is mounted on the outer side of the guide block 4 through the first sliding groove 30 and can slide left and right relative to the guide block 4. The locking mechanism includes a protrusion 31 provided on the outer side of the first rotating shaft 3, a third sliding groove 1301 opened on the side wall of the rotating hole 130, and a first elastic member 5. The protrusion 31 is placed in the third sliding groove 1301. When the first rotating shaft 3 rotates, it will drive the protrusion 31 to slide along the third sliding groove 1301. In the absence of external force, the first elastic member 5 will push the first rotating shaft 3 to slide outward relative to the guide block 4 through its elastic force.

[0038] like Figure 6 As shown, the bottom of the third sliding groove 1301 is also provided with a first locking groove 1302 and a second locking groove 1303. Figure 1 As shown, when the front handle body 11 rotates to the cutting knife state, the first elastic member 5 will push the protrusion 31 of the first rotating shaft 3 to cooperate with the first locking groove 1302. At this time, under the cooperation of the protrusion 31 and the first locking groove 1302, the first rotating shaft 3 of the front handle body 11 cannot rotate along the rotating hole 130 of the middle handle body 13, that is, the front handle body 11 and the middle handle body 13 remain relatively fixed, and because the middle handle body 13 and the front handle body 11 and the rear handle body 12 form a linkage structure, when the front handle body 11 cannot rotate relative to the middle handle body 13, the front handle body 11 cannot rotate relative to the rear handle body 12. Therefore, the front handle body 11, the middle handle body 13 and the rear handle body 12 remain relatively fixed at this time, so that the front handle body 11 can be locked in the cutting knife state, ensuring the structural stability of the tool in the cutting knife state. Figure 3 As shown, when the front handle body 11 rotates to the bayonet state, the first elastic member 5 pushes the protrusion 31 of the first rotating shaft 3 to cooperate with the second locking groove 1303, so that the front handle body 11 can be locked in the bayonet state, ensuring the structural stability of the knife in the bayonet state. In addition, when the knife is locked in the cutting state or the bayonet state, the user can press the first rotating shaft 3 to make the protrusion 31 disengage from the locking groove to release the lock, and the unlocking operation is convenient.

[0039] For example Figure 4 As shown, the first elastic member 5 is a first spring arranged in the first slide groove 30, and a spring groove 41 is provided on the outer side of the guide block 4. The first spring is installed in the spring groove 4, which can improve the installation stability of the first spring. The two ends of the first spring are respectively against the bottom of the first slide groove 30 and the bottom of the spring groove 41. In the absence of external force, the first spring will push the first rotating shaft 3 to slide outward relative to the guide block 4 through its elastic force.

[0040] Embodiment 3

[0041] This embodiment is a further improvement on the tool structure of the second embodiment, and the improvement is that: Figure 7 , 8 As shown, the front handle body 11 comprises a left front handle piece 111 and a right front handle piece 112 which are arranged opposite to each other. The rear end of the blade 2 is hinged to the front end position between the two front handle pieces, and the blade 2 can be rotated to open and folded relative to the two front handle pieces. When the knife is not in use, the blade 2 can be rotated and folded to the position between the two front handle pieces to protect the blade 2, and the size of the knife can be reduced, making it convenient to carry and store the knife.

[0042] like Figure 8 , 9As shown, the above-mentioned tool also includes a locking mechanism for locking the blade 2 in the open state, the locking mechanism includes a locking block 61, a push rod 62 connected to the left end face of the locking block 61, a button 63, and a second spring 64, the left end of the push rod 62 passes through the left front handle piece 111, the button 63 is connected to the left end of the push rod 62, and the button 63 is located at the outer position of the left front handle piece 111, the tail end of the blade 2 is provided with a bayonet 21 that cooperates with the locking block 61, the inner side of the right front handle piece 112 is provided with a second slide groove 1121, and the locking block 61 is placed in the second slide groove 1121 and can slide left and right relative to the second slide groove 1121. When in use, when the blade 2 is rotated to the open state, the second spring 64 will push the locking block 61 to slide leftward along the second slide groove 1121 through its own elastic force and cooperate with the bayonet 21, at this time, the blade 2 cannot rotate under the cooperation between the bayonet 21 and the left end of the locking block 61, so that the blade 2 can be locked in the open state. When the button 63 is pressed to push the locking block 61 to slide rightward along the second sliding groove 1121 and disengage from the latch 21 , the blade 2 can be unlocked in the open state, so that the blade 2 can be rotated and folded.

[0043] In addition, a positioning column 7 is provided at the front end position between the left front handle piece 111 and the right front handle piece 112. When the blade 2 is rotated to the open state, the rear end surface of the blade 2 abuts against the positioning column 7. At this time, the positioning column 7 can prevent the blade 2 from excessively rotating in the opening direction, and can also position the blade 2 in the open state, so that the left end of the locking block 61 can be better aligned with the position of the bayonet 21 and cooperate more easily.

[0044] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
