Abstract

The utility model relates to a folding knife, comprising a knife handle and a cutting blade connected on the knife handle and being capable of being folded in the knife handle; a locking key sheathed with dual-spring bars is arranged on the knife handle, the locking key moves in a hole site the knife handle is provided with; the locking key is in contact with the cutting blade, and the two ends of the locking key expose; recess areas (A5), (B5) which can be blocked and embedded with the locking key are arranged on the cutting blade, the dual-spring bars for supporting and going against the locking key to the direction of the cutting blade is arranged in the knife handle; the dual-spring bars are respectively arranged in slot positions arranged in an inner cavity of the knife handle, the A1 ends of the spring bars are respectively buckled at the two ends of the locking key, and the B2 ends of the spring bars are respectively buckled on the hole site the knife handle is provided with for realizing the elasticity needed by the cutting blade and a keystoke. The locking key sheathed with dual-spring bars and arranged on the knife handle is adopted for leading the locking key to be blocked and embedded in the recess position (A5) arranged on the cutting blade when the cutting blade unfolds, thus ensuring the cutting blade to not be folded backwards when being used by a user; and the recess position (B5) is arranged on the cutting blade, when the cutting blade is folded in the knife handle, the locking key is blocked and embedded on the recess position (B5), thus effectively preventing the cutting blade from being unfolded when the folding knife is carried; the folding knife has simple structure and is compact; besides, the using is safe, and the knife is artistic and appropriate.

Description

A kind of convertible pocket knife

Technical field

The utility model relates to five metals cutter manufacturing technology field, is a kind of convertible pocket knife specifically.

Background technology

At present, the Foldable knife kind of being sold on the existing market is of all kinds, and the type Foldable knife is simple in structure, and it is simple in structure, and is easy to use, is fit to very much the consumer and welcomes.But present most of Foldable knife all is to rely on side chain or sincere tail lock to fix blade, and design is an impediment to the outward appearance of himself, the aesthetic feeling image of badly damaged cutter like this.

The utility model content

The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, provides a kind of simple in structure, compactness, proper a kind of convertible pocket knife safe in utilization and attractive in appearance.

The utility model is to be achieved through the following technical solutions:

A kind of convertible pocket knife, comprise handle of a knife (1) and be connected on the handle of a knife and can be equivalent in blade (2) in the handle of a knife, the locking key (3) that is with dual spring bar (4) is set on the described handle of a knife, locking key is movable in the position, hole (8) that handle of a knife is provided with, locking key contacts with blade and expose at two ends, and blade is provided with and can allows recess (A5), (B5) of locking key inlay card.

Be provided with the dual spring bar that a top locking key advances to insert orientation in the described handle of a knife, the dual spring bar is located at respectively in the groove position (6) that the handle of a knife inner chamber is provided with, be provided with the position, hole in the groove position and spring be fixed in the handle of a knife groove position in pairs, effectively avoided occurring when using the loosening phenomenon that walks or come off of spring by rivet (7).

The A1 head of described dual spring bar (4) is buckled in the two ends of locking key (3) respectively, and the B2 head of spring is buckled in respectively on the position, hole that handle of a knife is provided with and realizes blade and the required elastic force of button.

The utility model compared with prior art has following advantage:

The utility model adopts the locking key that is with the dual spring bar is set on handle of a knife, the locking key inlay card was on the recess (A5) that blade was provided with when blade was launched, guaranteed that the user the phenomenon that blade is back amounted to can not occur in use, and also be provided with recess (B5) on the blade, the locking key inlay card is on recess (B5) when blade is amounted in handle of a knife, avoided jack knife the phenomenon that blade launches to occur carrying Shi Buhui effectively, and it is simple in structure, compactness, safe in utilization and attractive in appearance proper.
