Abstract

The utility model discloses a new type of folded knife, comprising a handle and a blade connected with the handle. The blade is provided with a hemispherical convex point on the end part connected with the handle; the handle is provided with a button for clamping and folding the blade. Besides, the handle is provided with a spring piece top button contacted with the blade; the blade is folded behind the handle and provided with hemispherical convex point clamped into the arc-shaped slide groove in the internal side of button. The utility model adopts I-shaped button to insert into and contact with the gap of blade. Besides, the blade is provided with the hemispherical convex point which is in frictional contact with the internal side of I-shaped button so that blade is folded in the handle more tightly. And the metal sleeve is arranged around the button to fill the space between the button and the handle, so as to improve precision and effectively avoid the loosening phenomenon between the button and the handle. The operator only needs to press the button to fold the blade with one hand; swing or inaccurate cutting and during cutting are eliminated. The new type of folded knife has simple structure, is convenient and practical and has comfortable handling sense.

Description

A kind of new type foldable pocket knife

Technical field

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

Background technology

At present, the folding pocket knife of being sold on the market all is made up of handle and the blade that is connected handle, it is simple in structure, practical compact, but the folding little cutter blade of the type used can occur long afterwards contacting between blade and the handle too loosening, phenomenons such as inaccurate can appear waving or cutting when the cutting object, and the pocket knife of such shape is provided with spring leaf pinning blade because of it adopts at the handle side, in folding pocket knife process with the side folding of female abutment spring leaf, because under the effect of spring leaf elastic force, mother refers to feel the uncomfortable user that also is easy to injure.

The utility model content

The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, provides a kind of simple and compact for structure, convenient and practical, can not occur between blade and the handle becoming flexible, and the folding pocket knife is also felt comfortable new type foldable pocket knife.

The utility model can be achieved through the following technical solutions:

A kind of new type foldable pocket knife, comprise handle (1) and be connected blade (2) on the handle, described blade with end that handle is connected on be provided with hemispheric salient point (7), handle (1) is provided with the button (3) that is used to tighten the blade after amounting to, button passes the position, hole (10) that handle is provided with and contacts with spring leaf (4), and its hemispheric salient point (7) snapped in the inboard set arc chute (9) of button after blade was folded to handle.

Described button cross section is worker's shape, and button passes the position, hole (10) that handle is provided with and contacts with spring leaf (4), and spring leaf is fixed on by the silk nail that a top button contacts with blade on the handle.

Offer breach (6) and button clamping mutually on the described blade, this blade breach effect is to avoid worker's shape button, makes it not hinder blade folding angle.

Described button neighboring is provided with the metallic sheath (8) that is used to be close to gap between button and handle and the blade breach.

The hemispherical salient point (7) of described blade is located in the recess of blade by ball and this ball exposes half and the salient point that forms.

The utility model compared with prior art has following advantage:

The utility model adopts the button and the set jagged contact of inlay card mutually of blade of worker's shape, and on blade, be provided with hemispherical salient point and the inboard CONTACT WITH FRICTION mutually of worker's shape button, it is compact more that blade is equivalent in the handle, the spring leaf that handle is provided with props up the top button and contacts with blade, and be provided with gap between metallic sheath filling button and the handle at the button periphery, make it increase precision, can avoid button and handle loosening phenomenon to occur effectively, when amounting to blade, only need press knob, one hand can once be finished, and has also stopped jackknife and can occur waving or cut phenomenons such as inaccurate when the cutting object, and it is simple in structure, convenient and practical, comfortable feel.

The specific embodiment

Come the utility model is further described below in conjunction with Figure of description:

Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, a kind of new type foldable pocket knife, comprise handle 1 and be connected blade 2 on the handle, described blade with end that handle is connected on be provided with hemispheric salient point 7, handle 1 is provided with the button 3 that is used to tighten the blade folding, button passes the position, hole 10 that handle is provided with and contacts with spring leaf 4, and its hemispheric salient point 7 snapped in the inboard set arc chute 9 of button after blade was folded to handle.

Described button cross section is worker's shape, and button passes the position, hole 10 that handle is provided with and contacts with spring leaf 4, and spring leaf is fixed on by the silk nail that a top button contacts with blade on the handle.

Offer breach 6 and button clamping mutually on the described blade, this blade breach fastens with the button of worker's shape and is contacted with this blade breach end by button, position-limiting action when making it not hinder blade folding angle and amount to.

Described button neighboring is provided with the metallic sheath 8 that is used to be close to gap between button and handle and the blade breach, strengthens its precision effect when this metallic sheath (8) is used for knob one folding pocket knife, makes it be not easy wearing and tearing and skew.

The hemispherical salient point 7 of described blade is located in the recess of blade by ball and this ball exposes half and the salient point that forms.

The utility model adopts the button and the set jagged contact of inlay card mutually of blade of worker's shape, and on blade, be provided with hemispherical salient point and the inboard CONTACT WITH FRICTION mutually of worker's shape button, it is compact more that blade is equivalent in the handle, the spring leaf that handle is provided with props up the top button and contacts with blade, and be provided with gap between metallic sheath filling button and handle and the blade breach at the button periphery, can avoid blade and handle and button and handle loosening phenomenon to occur effectively, also stop jackknife and phenomenons such as inaccurate when the cutting object, can occur waving or cutting, it is simple in structure, convenient and practical, comfortable feel.
