Description
The utility model relates to a kind of cutter of fixed structure with lock.Cutter of a great variety, some cutter has latch-up structure, make blade be in upright user mode and secure lock on handle of a knife; It is by the handle of a knife of band tool magazine, and blade that handle of a knife is hinged and latch-up structure are formed.Latch-up structure if any a kind of back of the body hook link that is provided with at the handle of a knife back, its blade is articulated on the handle of a knife with axle, knife back end face at heel is provided with a groove, the rear end of hinged back of the body hook link on handle of a knife, and the effect by spring, make the leading section of back of the body hook link embed groove, and make blade be locked in upright user mode; But after finishing using, just must press to back of the body hook link rear end with a hand application of force, make back of the body hook link leading section break away from groove, and carry on the back with another hand push push type broach, blade is folded in the tool magazine of handle of a knife, the locking of blade on handle of a knife just promptly opened and the pass is closed promptly foldingly, must with the hands operate, and can realize.Also has a kind of side plate latch-up structure in the handle of a knife tool magazine, claim side chain again, it is an end (rear end) of reinforcing spring leaf on left side in the handle of a knife tool magazine or the right plate, and the other end of spring leaf (front end) contacts the end at heel, realizes that blade is locked in upright user mode; After using, if when the rear end of its spring leaf presses on left plate in the tool magazine, at this moment, just can push spring leaf to the hand thumb application of force, make the leading section of spring leaf break away from the heel end, and fold in the tool magazine by the blade pass is closed with forefinger simultaneously.If but when going to operate with left hand this moment, be very much to cast aside to turn round, even unfeasible.Unless the rear end of spring leaf is fixed on the interior right plate of tool magazine, operate just be fit to left hand.When electricity is exactly one-handed performance, there is left hand and right hand not.The latch-up structure of comprehensive above two kinds of cutters, its weak point are obviously as can be known, their manual operation, or must make with the hands; Promptly use one hand, electricity has the right-hand man not.Therefore, its manual operation is loaded down with trivial details is very much inconvenience with manipulating.
Based on defective that exists in the above-mentioned technology and deficiency, the purpose of this utility model provides a kind of cutter of fixed structure with lock, it not only makes the blade of cutter have the function of locking (unlatching) He Guanhe (folding), and no matter is that left hand, the right hand only need singlehanded thumb just can finish the locking of blade and the purpose that close the pass.
The purpose of this utility model can be achieved by following measure, the cutter of fixed structure with lock is by the handle of a knife of band tool magazine, blade that handle of a knife is hinged and latch-up structure are formed, technology special feature of the present utility model is, its latch-up structure is: on the knife back end face of heel portion lockplate is housed, one end of lockplate is hinged on the knife back with axle, the other end of lockplate is provided with lock, be connected with handle of a knife backboard lock, in the blade groove below lockplate, spring leaf be housed, and the connecting axle that makes lockplate pass spring leaf below, the handle of a knife that will have tool magazine makes it hinged with axle and blade, overlaps the lockplate of packing in the knife back end of heel portion.It is the rectangular flute profile that Open Side Down up at the end that lockplate is made the gate-type shape, end (rear end) at the ABC of shape lockplate of the knife back end of heel portion cover, lockplate is hinged on the knife back with axle, and the other end of lockplate (front end) design has lock, open to lock and be connected the structure that lock connects and have varied: circular, square, hole, axle plug-in type with the handle of a knife backboard, promptly the Front-end Design at lockplate has lockhole or lock shaft, the corresponding design on the backboard of handle of a knife has lock shaft or lockhole, by cooperatively interacting, use the lock jail.Also have a kind of hook snap type, promptly make hook or button at the front end of lockplate, corresponding making on the handle of a knife backboard buckled or hook, and they cooperatively interact and are locked the jail, secondly also adopt Embedded lock ... Deng.For the ease of the application of force of singlehanded thumb, on lockplate, be set with the block cover of open and close, open and close block cover and also make portal structures, be sleeved on the lockplate.The groove of blade below the lockplate, general and blade fuses, the spring leaf of in groove, packing into, the connecting axle that below spring leaf, passes, it passes between a shape lockplate biside plate, pass spring leaf below, can rely on the elastic force of spring leaf to act on lockplate like this, so that make lockplate lock jail on the handle of a knife backboard.Firm behind the handle of a knife backboard when the front end lock of lockplate, promptly blade is in upright user mode; After cutter uses, as blade is folded in the tool magazine, actual is exactly that the blade pass is fashionable, as long as this moment is with any one hand, the no matter left hand or the right hand, and promptly singlehanded thumb forward pushing opens and closes block cover, even the lock breakdown of the front end of lockplate, make lockplate leave the handle of a knife backboard, continue, just the blade pass can be closed and fold in the handle of a knife tool magazine with the thumb forward application of force.When using as cutter, even blade when tool magazine is stretched, as long as force in the open and close block cover with singlehanded thumb backspace, just can make the blade unlatching extend out to upright user mode, the front end of lockplate is locked in again on the handle of a knife backboard, uses for people.Thereby just realized the purpose of the function of singlehanded thumb manual operation locking blade and folding blade.
Owing to adopt the such scheme can be in the locking and folder function of the blade of realizing cutter, also can realize with any hand the thumb manual operation, its action is simple, easy operating is very convenient.
Down and in conjunction with the accompanying drawings and embodiments to this practicality and novel further detailed explanation.
