Description

Technical Field

[0001] The utility model relates to the technical field of knives, in particular to a portable folding knife. Background Art

[0002] The blade of the folding knife commonly used at present can be folded into the blade groove of the handle through a rotating shaft structure. The general structure of this folding knife is a handle with a blade groove. When it is needed, the blade is opened from the blade groove, and the blade is folded when not in use.

[0003] In the prior art, the folding knife storage process generally requires one hand to hold the knife handle and the other hand to press the knife back for storage. When encountering special usage scenarios, it is impossible to store the knife with one hand. Utility Model Content

[0004] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide a portable folding knife, so as to realize convenient and quick storage and achieve the purpose of storing the knife by one-hand operation.

[0005] Specifically, the utility model provides a portable folding knife, comprising a handle portion and a blade portion; the blade portion is rotatably connected to the handle portion; an integrally formed pressing piece is extended on one side of the connecting end of the blade portion; in the unfolded state, the blade portion can be stored and folded by pressing the pressing piece with one hand.

[0006] The primary inventive point of the utility model is that a pressing plate is designed below the blade portion, and the pressing plate is an integrally formed structure with the entire blade portion. When the blade portion is unfolded, the pressing plate extends from the side of the handle portion. The pressing plate can be pressed by the thumb and the back of the blade portion can be lightly tapped with the index finger to achieve one-handed folding.

[0007] Furthermore, one side of the blade portion is a blade edge, and the other side is a blade back, and an angle α between the pressing sheet and the blade edge is 100-120°.

[0008] The pressing plate of the utility model is arranged on the side where the blade is located; in order to prevent the blade from hurting the hand, the pressing plate designed in the utility model is tilted downward, and the corresponding upper side of the handle part is also tilted downward, so that the angle α between the pressing plate and the blade part is an obtuse angle, so as to prevent the position of the blade from hurting the hand when pressing. More preferably, in some embodiments of the utility model, the angle α between the pressing plate and the blade is 105-115°.

[0009] Furthermore, a groove is provided at the connection between the pressing sheet and the blade. The groove is semicircular, so that when the thumb presses downward, the side of the thumb will not touch the blade, which is safer.

[0010] Furthermore, a pressing position is provided on the other side of the connecting end of the blade portion; the pressing position is corrugated.

[0011] In order to realize more convenient folding of the blade, when the thumb presses the pressing sheet, the angle α between the blade and the handle is reduced, and the index finger can press the other side of the connecting end of the blade to provide a pressing position, which is designed below the back of the blade to facilitate the index finger operation. If the index finger fails to completely fold, the thumb can be used to assist in pressing the back of the blade to achieve complete folding. The entire storage and folding process is simple, convenient and quick.

[0012] Furthermore, a first stop shaft is provided on the other side of the connecting end of the blade portion.

[0013] The first stop shaft is used to limit the outer edge of the blade portion to have room when the blade portion is stored, so that the blade portion will not completely enter the scabbard, which is convenient for the next deployment.

[0014] Furthermore, the portable folding knife of the utility model also includes a second stop shaft arranged inside the handle portion, and the lower side of the blade portion is provided with a first locking hole and a second locking hole; when the blade portion is unfolded, the second stop shaft is engaged in the first locking hole; when the blade portion is folded, the second stop shaft is engaged in the second locking hole.

[0015] In order to further improve the stability of the knife after unfolding and folding, to avoid safety hazards caused by the natural unfolding of the knife during folding and carrying, or the unstable rebound folding of the folding knife during use; the utility model is designed with a first locking hole and a second locking hole; the second stop shaft is designed in the scabbard; when the blade is fully unfolded or folded, the position of the blade is fixed by matching the corresponding first locking hole and second locking hole.

[0016] Furthermore, the handle portion includes a first handle and a second handle, and the blade portion is arranged between the first handle and the second handle; the sides of the connecting ends of the first handle and the second handle and the blade portion are also provided with wavy patterns; and a back clip is also provided on the outer side of the first handle.

[0017] The design of the wave pattern matches the wave shape of the pressing position, which is convenient for identifying the pressing position. The design of the back clip can facilitate the carrying or hanging storage of the folding knife.

[0018] More preferably, the handle portion further comprises a side locking piece and a cover piece; the side locking piece fits the inner side of the first handle; the cover piece fits the inner side of the second handle; the blade portion is arranged between the locking piece and the cover piece. A scabbard is formed between the locking piece and the cover piece, so that the blade portion can be embedded between the two after being stored.

[0019] Furthermore, the portable folding knife further comprises a sacrum; the sacrum is L-shaped and fixed between the locking plate and the cover plate by a tooth tube. The sacrum is arranged at the closed end of the handle part, specifically clamped between the side locking plate and the cover plate, and fixed by a tooth tube. After the blade part is folded, the blade side is in contact with the sacrum.

[0020] More preferably, an integrally formed nail remover is extended from the end of the sacrum.

[0021] In order to expand the function of the folding knife of the utility model, the utility model is provided with a nail remover at the end of the sacrum, preferably a flat-blade screwdriver; the nail remover extends from the handle and can be used to screw the flat-blade screw.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The folding knife of the utility model has a simple and compact structure. Through the design of the pressure piece on the blade side and the design of the pressing position on the back of the knife, the knife can be folded with one hand, which is more convenient to use.

[0024] The utility model takes into account the characteristics of hand force, and designs the blade and the pressing plate to be at an obtuse angle to avoid hand injury during the folding process. In addition, the utility model also designs a double locking structure, so that the blade can be fixed and locked in both the unfolded and folded states, thereby improving the stability of use.

[0025] The utility model also designs a back clip on the handle for easy carrying and storage; and designs a nail remover to expand the function of the folding knife, making it more practical. BRIEF DESCRIPTION OF THE DRAWINGS
