Detailed Description

The present invention will be described in further detail with reference to the drawings, wherein like elements are designated by like reference numerals, wherein the terms "front", "rear", "left", "right", "upper" and "lower", "bottom" and "top" used in the following description refer to the orientation in the drawings, and the terms "inner" and "outer" refer to the orientation toward or away from the geometric center of a particular element, respectively.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a folding knife with simple structure and smooth opening and closing comprises a knife handle 1, a folding channel 16 is arranged on the right side of the knife handle 1, a blade 8 is arranged in the folding channel 16, a connecting ring 13 is arranged on the blade 8, a fixed tube 6 is movably connected in the connecting ring 13, a circular groove 7 is arranged on the knife handle 1, the fixed tube 6 is fixedly arranged in the circular groove 7, an elastic strip 3 is integrally formed on the left wall of the knife handle 1, a small groove 5 is arranged on the right inner wall of the elastic strip 3, two ceramic beads 15 are arranged on the right side in the small groove 5, the friction force between the two ceramic beads 15 and the folding channel 16 on the knife handle 1 can be reduced when the blade 8 rotates back and forth, so that the resistance of the blade 8 moving back and forth can be reduced, and the blade 8 can be more smooth when being folded back and forth and opened, just so can the more laborsaving folding sword of use of convenience of customers, thereby can improve user's experience, fixed mounting has connecting block 14 on the blade 8, connecting block 14 and go-between 13, elongated slot 9 has been seted up to 8 upsides of blade, two inner walls are the arc around the elongated slot 9, 1 left side of handle of a knife is the arc, arc groove 10 has been seted up on 1 right side of handle of a knife, two ceramic pearl 15 are punching press inlet groove 5 bottoms, can convenience of customers clip blade 8 more through elongated slot 9 on the blade 8, thereby can further convenience of customers fold and open blade 8, through arc groove 10 and the left arcwall face of handle of a knife 1 on 1 right side of handle of a knife, can improve the effect of holding when handle of a knife 1 is held to the user, thereby can improve user's use experience.

The same side of the periphery of the connecting ring 13 and the cutting edge is provided with a groove 2 matched with the ceramic bead, and the other side is provided with an inclined plane 4. When the insert is closed, the grooves match the ceramic beads, and the top arcs of the beads fit into the grooves 2, as shown in fig. 5. As shown in fig. 6, when the blade is unfolded, the top arc of the ceramic bead is located on the side of the bevel. When the blade rotates, the circular arc part of the periphery of the connecting ring 13 contacts with the top arc surface of the ceramic bead. The groove 2 and the inclined plane 4 on the periphery of the connecting ring 13 play a role in positioning, and the blade is not easy to rotate when no external force is exerted.

The principle of the technical scheme is as follows: elastic strip 3 and 1 integrated into one piece of handle of a knife, elastic strip 3 right sides and handle of a knife 3 have the fluting, microgroove 5 promptly, and when the blade opened and shut, because elastic strip itself is flexible, the width between its and the handle of a knife can change slightly, and the gap between elastic strip 3 right sides and the handle of a knife 1 enlarges slightly promptly, plays the effect of a spring, makes opening and shutting of blade have certain resistance, has improved the security. If the blade is directly contacted with the elastic strip, the friction resistance of materials between metals is very large, such as a titanium alloy handle and a stainless steel blade, and the materials belong to the contact friction between points and surfaces.

In use, on the one hand: the ceramic beads can reduce the friction force between the blade and the folding channel on the knife handle when the blade rotates back and forth, so that the resistance of the blade to move back and forth can be reduced, the blade can be folded back and forth and opened more smoothly, a user can use the folding knife more conveniently and more laborsavingly, and the experience of the user can be improved; on the other hand: the blade can be clamped by the user more conveniently through the long groove in the blade, so that the blade can be further folded and opened by the user conveniently, the effect of holding can be improved when the user holds the knife handle through the arc groove on the right side of the knife handle and the arc-shaped surface on the left side of the knife handle, and the use experience of the user can be improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
