This proficiency is caught handle of a knife, take out or close on the other hand the cutter of blade, in the blade taking-up or folding, in the time of the most dangerous often, be no lack of a lot of people in life because operating on or hurting because of carelessness the hand of contactor blade when closing cutter, therefore, this cutter is still with certain danger, especially in urgent need, injured possibility is larger.
In addition, this cutter usually can be because certain accidental strength of touching or getting rid of causes cutter to be opened in folding, the danger of the injury that also brings.When the dress blade, due to inherent structure, cause filling the allowing blade replacement effort, tension when cutter is folding has increased folding difficulty.
The utility model content
The defective that exists in order to overcome above-mentioned prior art, the utility model provide a kind of singlehanded cutter formula jackknife that closes, and can realize singlehanded to the opening or folding of cutter, convenient and safe.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of singlehanded cutter formula jackknife that closes comprises cutter head section and handle of a knife section, establishes blade in described cutter head section, and described cutter head section is provided for the blade switch of blade loading and unloading and is used for the folding switch that described cutter head section and described handle of a knife section fold.
As preferably, blade switch described in the utility model comprises the button that is arranged on cutter head section surface, the inner shell fragment that is connected with described button that arranges of cutter head section.
As preferably, folding switch described in the utility model comprises the push button that is arranged at cutter head section surface and the spring that is arranged at cutter head section inside, and described push button one end extends to that described cutter head section is inner to offset with described spring, and other end setting is the top tongue of projection to the right.
As preferably, cutter head section described in the utility model and described handle of a knife section are for being flexibly connected.
As preferably, establish shoulder pole and the leaf spring that is connected with described shoulder pole, the groove that described shoulder pole one end setting and described top tongue coincide in handle of a knife described in the utility model section.
The beneficial effects of the utility model are, two switches all are arranged on cutter head section, make one hand can complete folding and opening procedure to cutter, and the dress blade is light and handy, quick, when folding, can not opened by the accidental power of touching easily, uses safety.

The specific embodiment:
Be easy to understand understanding in order to make creation characteristic of the present utility model, technological means and to reach purpose, further set forth the utility model below in conjunction with accompanying drawing.
Referring to a kind of singlehanded cutter formula jackknife that closes of Fig. 1～Fig. 6, comprise cutter head section 1 and handle of a knife section 2, establish blade 13 in described cutter head section 1, described cutter head section 1 is provided for the blade switch 3 of blade 13 loading and unloading and is used for the folding folding switch 4 of described cutter head section 1 and described handle of a knife section 2.Described blade switch 3 comprises the button 31 that is arranged on cutter head section 1 surface, and cutter head section 1 inside arranges the shell fragment 32 that is connected with described button 31, and shell fragment 32 is used for kayser and lives blade 13.Described folding switch 4 comprises the push button 41 that is arranged at cutter head section 1 surface and the spring 42 that is arranged at cutter head section 1 inside, and described push button 41 1 ends extend to described cutter head section 1 inside and offset with described spring 42, and other end setting is the top tongue 43 of projection to the right.Described cutter head section 1, is preferably by hinge 5 and connects for being flexibly connected with described handle of a knife section 2.Establish shoulder pole 21 and the leaf spring 22 that is connected with described shoulder pole 21 in described handle of a knife section 1, the groove 23 that described shoulder pole 21 1 end settings and described top tongue 43 coincide.
Cutter folds principle:
When operating on, top tongue 43 embeds in the groove 23 of shoulder pole 21 1 ends, and the dextrad elastic force of spring 42 makes shoulder pole 21 keep its straight state, reaches the effect of locking, and cutter head section 1 namely can voluntary activity.Turn left with the push button 41 that thumb is stirred on folding switch 4,42 extruding left of spring, top tongue 43 withdraws from from groove 23, at this moment, cutter head section 1 can be folded up with handle of a knife section 2 and realize closing cutter, after closing cutter, shoulder pole 21 upwarps slightly, and leaf spring 22 withstands handle of a knife section 2 inside.In this case, when jackknife not on belt the time, clasp is at the reverse side of handle of a knife section 2, health may can be encountered unintentionally cutter head section 1 part when squatting down, if this moment, cutter head section 1 was at non-resistance or loosening state, cutter head section 1 just is easy to close not firm, but the leaf spring 22 of this moment heads in handle of a knife section 2 inside, namely produce the effect of thrust, even health touching once in a while, cutter head section 1 can not be opened easily yet, still can keep closing the cutter state, has therefore guaranteed to close the safety under the cutter folded state.
Acting as of leaf spring:
Can play the effect of lever when 1, opening;
2, after cutter is folding, can open the effect that resets, cutter head section is being touched in situation unintentionally, can just not open easily.
Blade loading and unloading principle:
When there is no blade 13 in cutter head section 1, the shell fragment 32 of blade switch 3 makes stuck point 33 raise, at this moment, and within blade 13 can being inserted cutter head section 1, the button 31 of blade switch 3 is down pressed, following shell fragment 32 is forced down, and stuck point 33 namely forces down down, and blade 13 can be put into stuck point 33 positions, hand unclamps, following shell fragment 32 is raised thereupon, and stuck point 33 namely is locked in 131 li of the breach of blade 13, reaches the effect that fixed blade 13 is installed.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
