Abstract

The utility model discloses a multifunctional key. The hand shank provides the functions of opening bottles, milling knife, screwdriver, nail file, bicycle wrench, etc. The volume and weight are the same with the existing keys.

Description

Multifunctional key

The utility model is a kind of multi-functional key.

Existing key, though use the material difference, big or small, different, except that unblanking, do not possess other function.

The purpose of this utility model is that a kind of new key will be provided, and makes the key of function singleness become a multi-functional small tools.

The volume and weight of this multi-functional key is identical with existing key, and its handle has bottle opener, Qi Daoqi, screwdriver, nail file, six functions such as spoke spanner, fork spanner voluntarily.This key has a shape and size and the identical breach of bottle opener on the multi-blade pocket knife in its handle edge one side, by edge one shallow slot is arranged at the offside of this breach, makes the shuttle of a projection of edge's formation, and the edge of shuttle and two are lower.End one side at handle has a rectangular indentation, and Dui Cheng opposite side has a bit of thin and flat edge of a knife with it.Parallel and fine and closely woven shallow slot of one fritter or shuttle are arranged on the plane of key handle.The hole used of string key is a regular hexagon hole, its size and a certain standard nut measure-alike.

This multi-functional key is easy to carry, and is easy to use, do not influence former unlocking function, and its cost does not almost increase.

Describe in further detail below in conjunction with accompanying drawing.

The breach that colludes like fish in key handle (1) left side shape among the figure is bottle opener (2), and its size and dimension is identical with bottle opener on the common multi-blade pocket knife.The shuttle of handle right side shape lunar tooth is Qi Daoqi (3), and this groove that is about 0.6 millimeter place opens a treaty 2 mm wides 0.5 millimeters deep at distance key edge forms, and the crescent shuttle is inboard high, the outside is low, two ends are low, and are middle high so that and the crescent shaped groove on the fruit blade match.During use with crescent shuttle on the key handle and the groove alignment on the fruit blade and compress.Can easily cutter be drawn back.Can replace opening fruit knife with nail tip.Screwdriver (4) is that a bit of thin and flat edge of a knife of outer rim is arranged at the edge of key handle, and its edge of a knife can be more outstanding a little, also can be concordant with the edge.Nail file (5) is that parallel and fine and closely woven shuttle of a fritter or shallow slot are arranged on the plane of key handle, identical on its structure and function and the common nail clipper.Spoke spanner (6) is advisable with the key that is used in bicycle lock voluntarily, is to have a rectangular channel at the key handle edge, can for increasing the arm of force, should open in close handle end in order to adjust bike spoke voluntarily.Fork spanner (7) is to change go here and there the circular hole of key originally as the regular hexagon hole into, and makes its size identical with a certain standard nut, also can increase by a regular hexagon hole to several different sizes.

The position of opening cutter device (3) and screwdriver (4) among the figure can exchange, but bottle opener (2) should not have a side of key bit so that when using firmly.

Because screwdriver and voluntarily the spoke spanner require that higher mechanical strength is arranged, so the material of making this key with stainless steel or than the alloy of hard for well.
