Description

Jack knife

Technical field

The utility model relates to a kind of jack knife, refers to a kind of jack knife that is provided with a cutter hub and a handle of a knife especially, and the user can utilize one hand that this cutter hub is stretched out this handle of a knife, and the user also can utilize one hand to take in this cutter hub to this handle of a knife.

Background technology

The existing jack knife that existing market is peddled is of a great variety, wherein a kind of jack knife, see also Figure 1 and Figure 2, this jack knife 1 is made up of a handle of a knife 100 and a cutter hub 110, wherein an end of this cutter hub 110 is to be articulated in the end of this handle of a knife 100 by one first pivot 120, still be provided with a blocking assembly 130 and an elastic parts 140 in this handle of a knife 100, this blocking assembly 130 is to be articulated in this handle of a knife 100 by one second pivot 131, one end of this blocking assembly 130 is resisted against on the end of this cutter hub 110, end extends towards the end in addition of this handle of a knife 100 in addition, and the end in addition of this blocking assembly 130 is provided with a pressure section 150, this pressure section 150 is to protrude from this handle of a knife 100, and an end of this elastic parts 140 is to be installed in this handle of a knife 100 interior positions away from this first pivot 120, end is resisted against on the end in addition of this blocking assembly 130 in addition, this elastic parts 140 can promote this blocking assembly 130, make this blocking assembly 130 these cutter hub 110 blockings are fixed on the state that stretches out in outside this handle of a knife 100, perhaps these cutter hub 110 blockings are fixed on the state that is accommodated in this handle of a knife 100, when the user will control this cutter hub 110, when making this cutter hub 110 stretch out or to take in to this handle of a knife 100 versatilely, be to pass through by this pressure section 150, the direction of this blocking assembly 130 towards this elastic parts 140 promoted, fix in order to the blocking that discharges 130 pairs of these cutter hubs 110 of this blocking assembly.

But, this pressure section 150 is subjected to collision accidentally or extruding for avoiding it, and under the automatic situation of user, the blocking that discharges 130 pairs of these cutter hubs 110 of this blocking assembly is fixed, make this cutter hub 110 produce and produce danger, so, this jack knife 1 is designed to when user's desire screws out this handle of a knife 100 with this cutter hub 110, must be earlier to be hold by one hand this handle of a knife 100, and pushing this pressure section 150 fixes in order to the blocking that discharges 130 pairs of these cutter hubs 110 of this blocking assembly, and pull simultaneously and get this cutter hub 110 with another, just this cutter hub 110 can be produced in this handle of a knife 100 outside this handle of a knife 100, that is, the user is pushing this pressure section 150, in order to the blocking that discharges 130 pairs of these cutter hubs 110 of this blocking assembly fixing after, still must make with the hands and just this cutter hub 110 can be produced in this handle of a knife 100.

Yet; this kindness has but caused another kind of crisis; when the user runs into special or urgent situation; and it is also only surplus singlehanded when available; be to use this jack knife 1 immediately to deal with emergency situation, for example: when a diver at diving, and an one hand is when being snarled by fishnet; promptly can't cut off this fishnet with this jack knife 1 at once, cause diver's life to be subjected to serious threat.

Moreover, when the user will be fixed on blocking this cutter hub 110 outside this handle of a knife 100, when going back in this handle of a knife 100 once more, must grip this handle of a knife 100 with whole palm earlier, and pushing this pressure section 150 fixes in order to the blocking that discharges 130 pairs of these cutter hubs 110 of this blocking assembly, and simultaneously with this cutter hub 110 of another hand propelled, make this cutter hub 110 be transferred in this handle of a knife 100, only, moment in cutter hub 110 is transferred to this handle of a knife 100, user's palm still is held on this handle of a knife 100, and changing on the moving-wire position of required process in this handle of a knife 100 with respect to this cutter hub 110, one is careless slightly, this cutter hub 110 that changes in this handle of a knife 100, promptly can hurt the palm that still is held on this handle of a knife 100, cause regretting of user.

In sum, how to design a kind of jack knife of innovation, improve the multiple shortcoming of traditional jack knife, make the user convenient, safer more in the use, promptly become the manufacturer of each manufacturing at present, design jack knife, desire most ardently an important topic of solution.

In view of this, for improving the shortcoming of existing jack knife, the creator is through the permanent research and experiment of making great efforts, and development and Design goes out a kind of jack knife of the present utility model finally, design clever thought in the hope of passing through by appearance of the present utility model and this jack knife, and can propose contribution society.
