Description
Technical field
The present invention relates to a kind of kitchen utensils, especially a kind of kitchen knife.
Background technology
Kitchen knife is common during people live and is indispensable kitchen utensils, and kitchen knife is very sharp, can cause serious consequence during improper use.Even if adult accidentally can injure oneself when cutting the dish, for muddled children, often there is great potential safety hazard when they touch kitchen knife.Present family is all two-earners family substantially, a children often people stay at home, naughty children can have horseplay within doors, and kitchen knife be substantially all placed on kitchen table top on or in cupboard, children are very easy to obtain, if children take kitchen knife to play, be very easy to occur accident, cause too late to regret consequence.
Summary of the invention
The present invention is directed to deficiency of the prior art; provide the kitchen knife that a kind of children of preventing use; there is protective sleeve; danger is caused after preventing children to be not intended to take kitchen knife; this protective sleeve can effectively prevent children from kitchen knife is taken out from protective sleeve, and adult can be very easy to a kitchen knife and takes out from protective sleeve simultaneously.Solve after present children are not intended to take kitchen knife and easily cause dangerous problem.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: the kitchen knife that a kind of children of preventing use, also comprise the broach shell matched with described cutter hub, described handle of a knife is provided with cavity, first back-up ring and spring stack is provided with in described cavity, described spring stack is provided with second back-up ring, first spring is provided with between described first back-up ring and described second back-up ring, described spring stack one end extends to outside described handle of a knife, the described spring stack other end is provided with outward-dipping annular protrusion, the rotation fixed mechanism that several match with described annular protrusion is also provided with in described cavity, described broach shell is provided with hold-down bars, described hold-down bars to stretch in described cavity and matches with described rotation fixed mechanism, described broach shell is also provided with the bayonet unit matched with described through hole, described bayonet unit comprises first fixed block and the second fixed block relative with described first fixed block position, described through hole is between described first fixed block and described second fixed block, described first fixed block is provided with and stirs projection, the one side of the relatively described second fixed block of described first fixed block is provided with first magnet, described second fixed block is provided with the second magnet relative with described first magnet, continuous print wave shape groove is provided with bottom described handle of a knife.Such setting, broach shell is provided with hold-down bars, during without kitchen knife, with broach shell, kitchen knife can be entangled, in the cavity simultaneously allowing hold-down bars be inserted in handle of a knife.In cavity, hold-down bars is first fixed by rotation fixed mechanism, and then user of service is relative with second fixed block first fixed block, allows first magnet and second magnet be attracted each other by through hole and pastes jail.When needing to use kitchen knife, need to pin spring stack always, allow and rotate fixed mechanism rotation, unlock hold-down bars, then break first fixed block and second fixed block into two with one's hands, allow first magnet and second magnet depart from, such broach shell just can depart from from kitchen knife.If separately by spring stack or break separately first fixed block into two with one's hands and second fixed block all cannot allow broach shell depart from kitchen knife body, needing two to operate could unlock simultaneously.This method of operating is very easy to adult, as long as inclination kitchen knife during adult's operation, then pin spring stack while holding handle of a knife with one, another hand breaks first fixed block and second fixed block into two with one's hands, takes advantage of a situation simultaneously and pulls broach shell, just can take out kitchen knife very efficiently.For children, this method of operating is very loaded down with trivial details, Most of children is with can not break first fixed block and second fixed block into two with one's hands according to spring stack always simultaneously, because kitchen knife itself has certain weight, children's strength is less and hand is also less, substantially so coherent action can not be made, even if break separately first fixed block and second fixed block into two with one's hands to children being all a very difficult action.If these two is not continuous print action, then cannot take out during kitchen knife.
In technique scheme, preferably, described annular protrusion cross section is triangle, and the one side that described annular protrusion contacts with described rotation fixed mechanism is outward-dipping inclined-plane.Such setting, allows when conveniently pressing spring stack and rotates fixed mechanism rotation, allows hold-down bars loose from rotation fixed mechanism.
In technique scheme, preferably, described rotation fixed mechanism comprises the first rotating shaft be arranged in described cavity, described first rotating shaft is provided with first dwang, described first dwang end thereof contacts is to the one side of described annular protrusion, the other end is provided with non-return projection, the convex cross section of described non-return is triangular in shape, second spring is provided with between described non-return projection and described cavity inwall, described second both ends of the spring is separately fixed on the protruding and described cavity inwall of described non-return, described hold-down bars top is provided with the round platform matched with described non-return projection.Such setting, can allow hold-down bars insert convenient, and simultaneously after hold-down bars inserts, second spring can stop non-return projection mobile, prevents hold-down bars from deviating from.
Compared with prior art; the invention has the beneficial effects as follows: there is protective sleeve; cause danger after preventing children to be not intended to take kitchen knife, this protective sleeve can effectively prevent children from kitchen knife is taken out from protective sleeve, and adult can be very easy to a kitchen knife and takes out from protective sleeve simultaneously.Solve after present children are not intended to take kitchen knife and easily cause dangerous problem.
