Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutters, in particular to a cutter with a superimposed structure. Background Art
[0002] A folding knife is a type of knife that can be folded. A folding knife mainly has a knife body that can be screwed into the handle by a pivot assembly at the front end of the handle. A safety buckle is installed in the knife body relative to the side of the knife body, and an elastic strip is installed relative to the rear end of the knife body. The knife body is unfolded by pulling the knife body for use.
[0003] When using the current folded knives, the user pulls the blade to unfold it. Due to the stability of the installation, the spring makes it difficult to pull the knife when it is folded, and it cannot be opened and closed quickly. In addition, there is no grinding structure on the blade after each use, so the knife will become blunt over time, affecting subsequent use, and extra time is needed to sharpen the knife.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a knife with a superimposed structure, comprising a knife handle arranged in a hollow shape, an inlet and an outlet being penetrated and opened near the upper end of one side of the knife handle, and sliding grooves are provided on the inner box walls on both sides of the inlet and the outlet, one side of the upper end of the knife handle is rotatably connected to a rotating rod through a bearing, the rod wall at the lower end of the rotating rod passes through the bearing and the side wall of the knife handle and extends into the inside of the knife handle, the lower end of the rotating rod is fixedly connected to a gear, and a slider is slidably connected in the sliding groove, and the side of the slider away from the sliding groove is respectively fixedly connected to a first rack plate and a second rack plate, a side of the upper end of the first rack plate away from the slider is fixedly connected to a folding knife through a support rod, and a side of the upper end of the second rack plate away from the gear is fixedly connected to a mounting block through a support rod, a side of the mounting block close to the blade of the folding knife is penetrated by a through groove with a whetstone inside, and the through groove is movably sleeved on one side of the blade of the folding knife.
[0006] Preferably, a side of the knife handle away from the inlet and outlet is provided with a plurality of slots arranged in a ring array, and magnetic blocks are fixedly connected in the slots.
[0007] Preferably, a turntable is fixedly connected to the rod wall at the top end of the rotating rod, a plug hole is penetrated through one side of the turntable, a magnetic rod is inserted into the plug hole, and the magnetic rod passes through the plug hole and is magnetically connected to a corresponding slot.
[0008] Preferably, the slide groove, the first rack plate and the second rack plate are all staggered.
[0009] Preferably, a plurality of anti-slip grooves are engraved on a side of the knife handle away from the inlet and outlet.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: by arranging a turntable, a rotating rod, a gear and a rack plate, the folding knife can be manually rotated when it is needed, so that the knife can be quickly unfolded or stored for easy operation, thereby increasing the convenience of using the folding knife. At the same time, the interaction between the two-way rack plate and the gear can drive the knife to pass through the through groove for grinding each time it is used, thereby avoiding the knife becoming blunt due to long-term use and requiring extra time for grinding.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-5The utility model provides a technical solution: a knife with a superimposed structure, comprising a knife handle 1 arranged in a hollow shape, an inlet and outlet 2 is penetrated and opened near the upper end of one side of the knife handle 1, and slide grooves 3 are opened on the inner box walls on both sides of the inlet and outlet 2, one side of the upper end of the knife handle 1 is rotatably connected with a rotating rod 4 through a bearing, the rod wall of the lower end of the rotating rod 4 passes through the bearing and the side wall of the knife handle 1 and extends into the inside of the knife handle 1, the lower end of the rotating rod 4 is fixedly connected with a gear 5, and a slider 6 is slidably connected in the slide groove 3, and the slider 6 is fixedly connected with a first rack plate 7 and a second rack plate 8 on the side away from the slide groove 3 respectively, a folding knife 9 is fixedly connected to the side of the upper end of the first rack plate 7 away from the slider 6 through a support rod, and a mounting block 10 is fixedly connected to the side of the upper end of the second rack plate 8 away from the gear 5 through a support rod, and a through groove 11 with a whetstone inside is penetrated on the side of the mounting block 10 close to the blade of the folding knife 9, and the through groove 11 is movably sleeved on one side of the blade of the folding knife 9.
[0019] A plurality of slots 13 arranged in a circular array are provided on the side of the knife handle 1 away from the inlet and outlet 2, and magnetic blocks are fixedly connected to the slots 13; a turntable 12 is fixedly connected to the rod wall at the top end of the rotating rod 4, and a plug hole 14 is penetrated through one side of the turntable 12, and a magnetic rod 15 is inserted into the plug hole 14. The magnetic rod 15 passes through the plug hole 14 and is magnetically connected to the corresponding slot 13, which is conducive to limiting the magnetic rod 15 by passing through the plug hole 14 and inserting it into the slot 13, so that it is convenient to use the knife handle 1.
[0020] The slide groove 3, the first rack plate 7 and the second rack plate 8 are all staggered, which is conducive to driving the folding knife 9 and the through groove 11 to move and grind each time the staggered first rack plate 7 and the second rack plate 8 move.
[0021] A side of the knife handle 1 away from the inlet and outlet 2 is engraved with a plurality of anti-skid patterns, which is beneficial to increase the stability of the knife handle 1 when it is used and held through the plurality of anti-skid patterns.
[0022] Specifically, when the utility model is used, when the folding knife 9 is needed, the handle 1 is held, and then the turntable 12 is turned. The turntable 12 is forced to drive the rotating rod 4 to rotate. The rotating rod 4 then stably drives the gear 5 to rotate under the rotation of the bearing. When the gear 5 rotates, the two sides will respectively mesh and drive the first rack plate 7 and the second rack plate 8. At this time, the second rack plate 8 moves into the handle 1 under the sliding limit of the slider 6 and the slide groove 3. When the second rack plate 8 moves, it simultaneously drives the mounting block 10 to move through the support rod, and the mounting block 10 will drive the penetrating The through slot 11 moves. Similarly, the first rack plate 7 cooperates with the support rod to drive the folding knife 9 to move toward the inlet and outlet 2 under the sliding limiting action of the slide slot 3 and the slider 6. As the folding knife 9 performs relative movement inside the through slot 11, the whetstone inside the through slot 11 will grind the blade when the folding knife 9 moves. At this time, the folding knife 9 will pass through the inlet and outlet 2 and move to the outside of the handle 1. Then the magnetic rod 15 will pass through the insert block 14 and be inserted into the magnetic block inside the corresponding slot 13 for magnetic limiting. Then the handle 1 is held to cooperate with the folding knife 9 for use.
[0023] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
