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, during improper use, can cause serious consequence.Even if adult accidentally can injure oneself when cutting the dish, for muddled children, when touching kitchen knife, they tend to occur great potential safety hazard.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 is all placed on the table top in kitchen or in cupboard substantially, 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; the kitchen knife that provides a kind of children of preventing to use; there is protective sleeve; prevent from causing danger after children are not intended to take kitchen knife; this protective sleeve can effectively prevent that children from taking out kitchen knife from protective sleeve, and adult can be very easy to a kitchen knife and takes out from protective sleeve simultaneously.Solved after present children are not intended to take kitchen knife and easily caused 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 matching with described cutter hub, on described handle of a knife, be provided with cavity, in described cavity, be provided with first back-up ring and spring stack, on described spring stack, be provided with second back-up ring, between described first back-up ring and described second back-up ring, be provided with first spring, 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, in described cavity, be also provided with the rotation fixed mechanism that several match with described annular protrusion, on described broach shell, be provided with hold-down bars, described hold-down bars stretches in described cavity and matches with described rotation fixed mechanism, on described broach shell, be also provided with the bayonet unit matching with described through hole, described bayonet unit comprises first fixed block and the relative second fixed block in first fixed block position with described, described through hole is between described first fixed block and described second fixed block, on described first fixed block, be provided with and stir projection, the one side of the described relatively described second fixed block of first fixed block is provided with first magnet, on described second fixed block, be provided with the second magnet relative with described first magnet, described handle of a knife bottom is provided with continuous wave shape groove.Arrange like this, on broach shell, be provided with hold-down bars, during without kitchen knife, can kitchen knife be entangled with broach shell, allow hold-down bars be inserted in the cavity in handle of a knife simultaneously.In cavity, hold-down bars is first rotated fixed mechanism and fixes, and then user of service is relative with second fixed block first fixed block, allows first magnet and second magnet be attracted each other and to be pasted jail by through hole.In the time of need to using kitchen knife, need to pin spring stack always, allow and rotate fixed mechanism rotation, release hold-down bars, then breaks first fixed block and second fixed block into two with one's hands, allows first magnet and second magnet depart from, and broach shell just can depart from from kitchen knife like this.If separately by spring stack or break separately first fixed block and second fixed block into two with one's hands and all cannot allow broach shell depart from kitchen knife body, need two operations simultaneously could releases.This method of operating is very easy to being grown up, and as long as when operation adult be inclination kitchen knife, then pins spring stack when holding handle of a knife with one, and another hand is broken 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 very efficiently kitchen knife.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 can not make so coherent action, even if break separately first fixed block into two with one's hands and second fixed block is all a very difficult action concerning children.If these two is not continuous action, cannot take out during kitchen knife.
In technique scheme, preferred, 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.Arrange like this, while conveniently pressing spring stack, allow and rotate fixed mechanism rotation, allow hold-down bars loose from rotating fixed mechanism.
In technique scheme, preferably, described rotation fixed mechanism comprises the first rotating shaft being arranged in described cavity, in described first rotating shaft, be provided with first dwang, described first dwang one end touches the one side of described annular protrusion, the other end is provided with non-return projection, the protruding cross section of described non-return is triangular in shape, between described non-return projection and described cavity inwall, be provided with second spring, 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 matching with described non-return projection.Arrange like this, can allow hold-down bars insert convenient, after hold-down bars inserts, second spring can stop non-return projection mobile simultaneously, prevents that hold-down bars from deviating from.
Compared with prior art; the invention has the beneficial effects as follows: there is protective sleeve; prevent from causing danger after children are not intended to take kitchen knife, this protective sleeve can effectively prevent that children from taking out kitchen knife from protective sleeve, and adult can be very easy to a kitchen knife and takes out from protective sleeve simultaneously.Solved after present children are not intended to take kitchen knife and easily caused dangerous problem.
