Description

Technical Field

[0001] The utility model relates to the technical field of chip cutting tools, in particular to a peeling knife. Background Art

[0002] A paring knife is a hand-operated tool used to peel thinning fruits such as loofahs, potatoes, and apples. It is also a common tool used in daily life. Existing paring knives generally include a knife holder and a handle connected to the holder. The holder has a mounting slot, and a blade is positioned at the notch of the slot. During use, the handle is grasped to operate the blade to peel the thinning fruit, making the peeling operation convenient.

[0003] However, the existing paring knife still has a disadvantage. That is, the knife holder and the handle of the existing paring knife are integrated into a structure, so the knife holder cannot be folded relative to the handle, resulting in a large size of the paring knife, which occupies a large space and is inconvenient to carry and store. In addition, the exposed blade is unsafe. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a peeling knife that can be easily carried and stored.

[0005] To achieve the above-mentioned purpose, the technical solution provided by the present invention is: a paring knife, comprising a knife holder with a blade, and a handle connected to the knife holder, a front end of the knife handle being provided with a receiving groove, the knife holder being placed in the receiving groove, the knife holder being able to slide relative to the receiving groove to an open state extending out of the receiving groove and a closed state retracted into the receiving groove, and when the knife holder is in the open state, the blade is located outside the receiving groove, the above-mentioned paring knife also includes a limiting member movably connected to the outer side of the knife handle, the limiting member can be converted to an open state and a folded state relative to the knife handle, when the knife holder slides to the open state, the limiting member in the folded state will limit the knife holder from sliding backward, and when the knife holder slides to the closed state, the limiting member in the folded state will limit the knife holder from sliding forward; and the limiting member in the open state will release the restriction on the knife holder.

[0006] In the above solution, when in use, the limiter can be rotated to release the sliding restriction on the blade holder, and then the blade holder can be pushed forward to slide to the open state where it extends out of the receiving slot. The limiter can then be rotated to the folded state to restrict the blade holder from sliding backward, thereby locking the blade holder in the open state. This makes it convenient for the user to grasp the knife handle and the limiter to operate the blade of the knife holder to peel fruit. When not in use, the limiter can be rotated again to release the sliding restriction on the blade holder, and then the blade holder can be pushed backward to slide to the closed state. The limiter can then be rotated to the folded state to restrict the blade holder from sliding forward, thereby locking the blade holder in the closed state. At this time, the blade holder and blade are stored in the receiving slot of the knife handle, thereby reducing the size of the peeler, making it convenient and safe to carry and store. The blade holder can be locked by rotating the limiter, making it easy to operate.

[0007] and rotating the sleeve to the open state will cause the slot to disengage from the slider, thereby releasing the blocking of the slider by the slot side wall, and the slider can now slide back and forth in the first slot.

[0008] Furthermore, the slider includes a slide seat provided on the side wall of the tool holder, and a locking block slidably engaged with the slide seat. The side wall of the second slot is provided with a second locking slot. When the slider engages with the second slot, the sliding locking block can slide into and out of the second locking slot. When the sliding locking block slides into the second locking slot, the locking block blocks the ferrule from rotating in the opening direction, thereby locking the ferrule in the folded state, preventing the ferrule from naturally rotating open and releasing the restriction on the slider's forward sliding; and when the sliding locking block disengages from the second locking slot, the locking of the ferrule is released, allowing the ferrule to rotate and open.

[0009] Furthermore, a first locking groove is formed on the side wall of the first slot. When the slider engages with the first slot, the sliding locking block can slide into and out of the first locking groove. When the sliding locking block slides into the first locking groove, it blocks the ferrule from rotating in the opening direction, thereby locking the ferrule in the folded state, preventing the ferrule from naturally rotating open and releasing the restriction on the slider sliding backward. When the sliding locking block disengages from the first locking groove, the ferrule is unlocked, allowing the ferrule to rotate and open.

[0010] In order to realize the structural function of sliding cooperation between the locking block and the sliding seat, a sliding hole is opened on the rear side of the above-mentioned sliding seat. The locking block includes a lock body and a lock head connected to the end of the lock body. The lock body is inserted into the sliding hole and can slide back and forth along the sliding hole. When the slider cooperates with one of the slots, the sliding locking block can make the lock head slide into and out of the lock slot corresponding to the slot.

[0011] Furthermore, the inner wall of the sliding hole is provided with a first locking groove and a second locking groove, and the side wall of the lock body is provided with a positioning protrusion. When the slider engages with one of the locking grooves, sliding the lock body until the positioning protrusion engages with the first locking groove causes the lock head to disengage from the locking groove of the locking groove, while sliding the lock body until the positioning protrusion engages with the second locking groove causes the lock head to slide into the locking groove of the locking groove. This solution, through the cooperation of the positioning protrusion and the locking groove, prevents the lock body from sliding naturally, thereby preventing the lock head from sliding into and out of the lock groove.

[0012] Furthermore, the lock body is provided with a through-hole, and the positioning protrusion is a V-shaped block disposed within the through-hole. The two ends of the open end of the V-shaped block are respectively connected to the front and rear side walls of the through-hole, and the tip of the V-shaped block protrudes from the side of the lock body, allowing the tip of the V-shaped block to engage and disengage with the buckle groove. Furthermore, the upper and lower sides of the V-shaped block are spaced from the opposite sides of the through-hole, allowing the V-shaped block to have good elastic deformation in the depth direction of the through-hole, thereby facilitating the engagement and disengagement of the tip of the V-shaped block with the buckle groove.

[0013] and rotating the sleeve to the open state will cause the positioning groove and the positioning block to disengage, thereby releasing the blocking of the positioning groove side wall to the positioning block, and at this time the positioning block can slide back and forth in the second slide groove.

[0014] Furthermore, the above-mentioned clamping sleeve includes a relative left plate, a right plate, and a connecting plate connected to the upper end between the two side plates, the first clamping slot and the second clamping slot are opened on the left side plate, the first slide groove is opened on the left side wall of the tool handle, the slider is arranged on the left side wall of the tool holder, the first positioning slot and the second positioning slot are opened on the right side plate, the second slide groove is opened on the right side wall of the tool handle, and the positioning block is arranged on the right side wall of the tool holder. The rear ends of the two side plates are rotatably connected to the rear end of the tool handle through a rotating shaft, and the clamping sleeve can be rotated around the rotating shaft relative to the tool handle to open and fold, and the sliders and positioning blocks on the left and right side walls of the tool holder slide along the first slide groove and the second slide groove on the left and right sides of the tool handle respectively, so that the tool holder can slide back and forth more smoothly.

[0015] Furthermore, a protrusion is provided at the rear end of the above-mentioned tool handle. When the ferrule is rotated to the open state, the rear end of the connecting plate abuts against the protrusion. At this time, the protrusion will prevent the ferrule from continuing to rotate in the opening direction, thereby limiting the opening of the ferrule.

[0016] The peeling knife of this utility model can realize the sliding opening and closing of the knife holder by one-hand operation, which is very convenient and quick to operate. The clamping sleeve can lock the knife holder in the open and closed states, which is convenient to use. In addition, the lock head and the lock groove cooperate to prevent the clamping sleeve from automatically rotating and opening, and the positioning groove and the positioning block cooperate to ensure that the knife holder and the slide seat will not slide naturally when in the open and closed states. This makes it easier to operate the lock head to slide into and out of the lock groove, and the locking of the knife holder is more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[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] Example 1

[0030] like Figure 1-4 As shown, the present invention provides a paring knife, comprising a knife holder 1 with a blade 2, and a handle 3 connected to the knife holder 1. The handle 3 has a front end provided with a receiving groove 31, and the knife holder 1 is placed in the receiving groove 31. The knife holder 1 can slide relative to the receiving groove 31 to an open state in which it extends outside the receiving groove 31, and a closed state in which it is retracted into the receiving groove 31. When the knife holder 1 is in the open state, the blade 2 is located outside the receiving groove 31. The paring knife further comprises a limiting member movably connected to the outside of the handle 3. The limiting member can be switched to an open state and a folded state relative to the handle 3. When the knife holder 1 slides to the open state, the limiting member in the folded state restricts the knife holder 1 from sliding backward. When the knife holder 1 slides to the closed state, the limiting member in the folded state restricts the knife holder 1 from sliding forward. The limiting member in the open state releases the restriction on the knife holder 1.

[0031] Specifically, the left side wall of the above-mentioned tool handle 3 is provided with a first sliding groove 32 connected to the accommodating groove 31, and the left side wall of the tool holder 1 is provided with a slider 11. The slider 11 extends out of the first sliding groove 32 and can slide along the first sliding groove 32. The above-mentioned limiting member is a clamping sleeve 4 that is rotatably connected to the outside of the tool handle 3. The clamping sleeve 4 can be rotated to open and fold relative to the tool handle 3. The side wall of the clamping sleeve 4 is provided with a first clamping groove 41 and a second clamping groove 42.

[0032] like Figure 3As shown, when the tool holder 1 slides to the open state, rotating the clamping sleeve 4 to the folded state will make the first clamping groove 41 cooperate with the slider 11. At this time, the rear side wall of the first clamping groove 41 will prevent the slider 11 from sliding backward, thereby locking the tool holder 1 in the open state. Figure 1 As shown, when the tool holder 1 slides to the closed state, rotating the clamping sleeve 4 to the folded state causes the second clamping slot 42 to engage with the slider 11. At this time, the front side wall of the second clamping slot 42 blocks the slider 11 from sliding forward, thereby locking the tool holder 1 in the closed state. Rotating the clamping sleeve 4 to the open state disengages the clamping slot from the slider 11, thereby releasing the obstruction of the clamping slot side wall on the slider 11. At this time, the slider 11 can slide back and forth in the first slide groove 32.

[0033] When the peeler of this embodiment is used, the sleeve 4 can be rotated to open first, and then the slider 11 can be slid forward to drive the knife holder 4 to slide to the open state, and then the sleeve 4 can be rotated to the folded state to complete the opening operation of the knife holder 1. At this time, the user can hold the knife handle 1 and the sleeve 4 by hand to operate the blade 2 of the knife holder 1 to peel the fruit. When the user holds the sleeve 4, the sleeve 4 will not automatically rotate to open, so that the first card slot 41 and the slider 11 remain in a matched state, thereby being able to firmly lock the knife holder 1 in the open state, and the peeling operation is convenient.

[0034] When not in use, the card sleeve 4 can be rotated to open, and then the knife holder 1 can be slid backward to the closed state, and then the card sleeve 4 can be rotated to the folded state so that the second card slot 42 cooperates with the slider 11, thereby locking the knife holder 1 in the closed state. At this time, the knife holder 1 and the blade 2 are stored in the accommodating groove 31 of the handle 3, thereby reducing the size of the peeler, making it convenient to carry and store, and safer.

[0035] The peeling knife of this embodiment can also realize the opening and closing of the knife holder 1 by one-hand operation, which is very convenient and fast. The specific operation method is: when the knife holder 1 and the card sleeve 4 are in the closed state, the user can grab the card sleeve 4 with one hand and swing the card sleeve 4 to rotate it open. At this time, the front end of the knife holder 1 faces the ground, so that the knife holder 1 automatically slides forward and opens under the action of its own weight and inertia. Figure 2 As shown, the card sleeve 4 is then swung and rotated to fold, at which time the slider 11 is matched with the first card slot 41, as shown Figure 3 As shown, at this time, the user can hold the clamping sleeve 4 and the tool handle 3 with one hand at the same time to complete the one-handed opening operation of the tool holder 1.

[0036] When the tool holder 1 is in the open state and the card sleeve 4 is in the folded state, the user can grab the card sleeve 4 with one hand and swing the card sleeve 4 to rotate and open it. At this time, the rear end of the tool holder 1 faces the ground, so that the tool holder 1 automatically slides backward and closes under its own weight, and then swings the card sleeve 4 to rotate and fold it. At this time, the slider 11 cooperates with the second card slot 44, as shown in FIG. Figure 1As shown, at this time, the user can complete the one-hand closing operation of the tool holder 1 by holding the ferrule 4 and the tool handle 3 with one hand.

[0037] Example 2

[0038] This embodiment is a further improvement on the structure of the peeling knife of embodiment 1, and the improvement is that Figure 5 As shown, the above-mentioned slider 11 includes a slide 111 provided on the left side wall of the tool holder 1, and a locking block 112 slidably fitted on the slide 111. A slide hole 110 is opened on the rear side of the slide 111. The locking block 112 includes a lock body 113 and a lock head 114 connected to the end of the lock body 113. The lock body 113 is inserted into the slide hole 110 and can slide back and forth along the slide hole 110.

[0039] like Figure 1 As shown, the rear side wall of the above-mentioned second card slot 42 is provided with a second locking slot 421. When the slider 11 cooperates with the second card slot 42, sliding the locking block 112 backward will cause the locking head 114 to slide into the second locking slot 421. At this time, the locking head 114 will prevent the card sleeve 4 from rotating in the opening direction, thereby locking the card sleeve 4 in a folded state, preventing the card sleeve 4 from naturally rotating and opening, and releasing the restriction on the forward sliding of the slider 11, making it more convenient to carry and store the peeler; and sliding the locking block 112 forward will cause the locking head 114 to disengage from the second locking slot 421, thereby releasing the lock on the card sleeve 4, so that the card sleeve 4 can be rotated to open.

[0040] like Figure 3 As shown, a first locking groove 411 is provided on the rear side wall of the above-mentioned first card slot 41. When the slider 11 cooperates with the first card slot 41, sliding the locking block 112 backward will cause the locking head 114 to slide into the first locking groove 411. At this time, the locking head 114 of the locking block 112 will prevent the card sleeve 4 from rotating in the opening direction, thereby locking the card sleeve 4 in a folded state, preventing the card sleeve 4 from naturally rotating and opening, and releasing the restriction on the backward sliding of the slider 11, ensuring the structural stability of the tool holder 1 in the open state, and making it more convenient and safe to use; and sliding the locking block 112 forward to cause the locking head 114 to disengage from the first locking groove 411, thereby releasing the lock on the card sleeve 4, so that the card sleeve 4 can be rotated to open.

[0041] As an improvement to this embodiment, Figure 5As shown, the right side wall of the sliding hole 110 is provided with a first latching groove 1101 and a second latching groove 1102, and the right side wall of the lock body 113 is provided with a positioning protrusion 1131. When the slider 11 is engaged with one of the latching grooves, sliding the lock body 113 until the positioning protrusion 1131 engages with the first latching groove 1101, causing the lock head 113 to disengage from the latching groove of the latching groove. Sliding the lock body 113 until the positioning protrusion 1131 engages with the second latching groove 1102, causing the lock head 113 to slide into the latching groove of the latching groove. In this solution, the positioning protrusion 1131 cooperates with the latching groove, and the latching groove acts as a damping force on the positioning protrusion 1131, preventing the lock body 113 from sliding naturally, thereby preventing the lock head 113 from sliding into and out of the latching groove. Therefore, during use, the user must forcefully push the lock head 114 to allow the lock body 113 to slide and drive the positioning protrusion 1131 out of the latching groove.

[0042] Specifically, if Figure 6 As shown, the lock body 113 defines a through hole 1130. The positioning protrusion 1131 is a V-shaped block positioned within the through hole 1130. The two ends of the open end of the V-shaped block are respectively connected to the front and rear side walls of the through hole 1130. The tip of the V-shaped block protrudes from the right side of the lock body 113, allowing the tip of the V-shaped block to engage and disengage with the buckle groove. Furthermore, the upper and lower sides of the V-shaped block are spaced apart from the opposite sides of the through hole 1130, allowing the V-shaped block to have good elastic deformation in the depth direction of the through hole, which makes it easier for the tip of the V-shaped block to engage and disengage with the buckle groove.

[0043] like Figure 3 、 5 As shown, the cross section of the blade 2 is an arc-shaped structure, a cutting hole 20 is opened in the middle of the blade 2, and the left and right side walls of the cutting hole 20 are provided with cutting edges 201, so that when the user pushes the handle 13 in the left and right directions, the blade 2 can be pushed to cut the outer skin of fruits and vegetables, making the operation more convenient and quick.

[0044] Among them, the lower side wall of the blade holder 1 of this embodiment is provided with a mounting groove 10, and the front and rear sides of the mounting groove 10 are respectively provided with insertion holes 13. The front and rear ends of the blade 2 are respectively inserted into the insertion holes 13 on the corresponding sides through the insertion posts 21. The blade 2 can be rotated along the insertion holes 13 through the insertion posts 21, so that the cutting edge 201 of the blade 2 can more easily fit the outer skin of fruits and vegetables, making peeling more convenient.

[0045] A stopper 14 is further provided on the inner side of the mounting groove 10 to limit excessive rotation of the blade 2. When the blade 2 rotates to abut against the side wall of the stopper 14, the stopper 1211 will prevent the blade 2 from continuing to rotate in the same direction, thereby preventing the blade 2 from excessively rotating and causing the cutting edge 201 of the blade 2 to lose contact with the outer skin of the fruit or vegetable and thus prevent the peeling.

[0046] Example 3

[0047] This embodiment is a further improvement on the structure of the peeling knife of the second embodiment. The improvement is that Figure 4 、 5 As shown in Figures 7 and 7, a positioning block 12 is provided on the right side wall of the tool holder 1, and a second slide groove 33 connected to the accommodating groove 31 is provided on the right side wall of the tool handle 3. The positioning block 12 extends out of the second slide groove 33 and can slide along the second slide groove 33. A first positioning groove 43 and a second positioning groove 44 are provided on the side wall of the ferrule 4.

[0048] When the tool holder 1 slides to the open state, rotating the sleeve 4 to the folded state will make the first positioning groove 43 cooperate with the positioning block 12. At this time, the rear side wall of the first positioning groove 43 will prevent the positioning block 12 from sliding backward, thereby ensuring that the tool holder 1 and the slide 111 will not slide backward in the open state, so that it is more convenient to push the lock head 114 to slide in and out of the first lock groove 411.

[0049] When the tool holder 1 slides to the closed state, rotating the ferrule 4 to the folded state will cause the second positioning groove 44 to cooperate with the positioning block 12. At this time, the front and rear side walls of the second positioning groove 42 will prevent the positioning block 12 from sliding forward and backward, thereby ensuring that the tool holder 1 and the slide 111 will not slide forward in the closed state, making it easier to push the lock head 114 into and out of the second locking groove 421. Rotating the ferrule 4 to the open state will disengage the positioning groove from the positioning block 12, thereby releasing the obstruction of the positioning groove side walls on the positioning block 12, and the positioning block 12 can now slide forward and backward in the second slide groove 33.

[0050] like Figure 2 、 8 As shown, the aforementioned clamping sleeve 4 includes a left side plate 45, a right side plate 46, and a connecting plate 47 connected to the upper ends between the two side plates. A first clamping slot 41 and a second clamping slot 42 are provided at the lower edge of the left side plate 45, and a first positioning slot 43 and a second positioning slot 44 are provided at the lower edge of the right side plate 46. The rear ends of the two side plates are rotatably connected to the rear end of the handle 3 via a rotating shaft 5, allowing the clamping sleeve 4 to be rotated, opened, and folded relative to the handle 3 about the rotating shaft 5. A protrusion 6 is provided at the rear end of the handle 3. When the clamping sleeve 4 is rotated to the open state, the rear end of the connecting plate 47 abuts against the upper side wall of the protrusion 6. At this time, the protrusion 6 prevents the clamping sleeve 4 from further rotating in the opening direction, thereby limiting the opening of the clamping sleeve 4. In addition, the protrusion 6 is also provided with a hanging hole 60, which facilitates hanging the peeler on items such as wall hooks through the hanging hole 60 for more convenient storage.

[0051] like Figure 9 As shown, the upper and lower side walls of the knife holder 1 of this embodiment are both provided with mounting grooves 10, and blades 2 and limit blocks 14 are both provided in the two mounting grooves 10, so that the peeling knife of this embodiment has two blades 2 for cutting the outer skin of fruits and vegetables, and is more durable to use.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
