Description

The new type foldable pocket knife

Technical field

The utility model relates to five metals cutter manufacturing technology field, is a kind of new type foldable pocket knife specifically.

Background technology

At present; The folding pocket knife kind of being sold on the existing market is of all kinds, but most of at present folding pocket knife all is to rely on side chain or sincere tail lock to fix blade, and such folding pocket knife structure is tradition relatively; Manufacturing procedure is many; Consumptive material is compared down no characteristic with other products, very sorry.

The utility model content

The purpose of the utility model is the shortcoming that overcomes above-mentioned prior art, and new type foldable pocket knife a kind of simple in structure, fashionable, convenient and practical, safe in utilization is provided.

The utility model is to realize through following technical scheme:

A kind of new type foldable pocket knife; Comprise handle of a knife and be connected on the handle of a knife and folding blade; Said handle of a knife tail end is provided with the control that is used for fixing blade, and an end of this control flexibly connects through screw and handle of a knife tail end, and the other end is provided with cross bar and contacts with the recess that the blade root is provided with.

Saidly be provided with the spring that offers the required elastic force of control at handle of a knife and control junction, this spring is fixed as central point with the fixture activity, and an end is buckled on first pin that handle of a knife is provided with, and the other end is buckled on second pin that control is provided with.

Said spring is a torsionspring.

Said blade root is provided with supplies with the groove position that cross bar slides.

Said control is made up of two identical and crooked braces of size, is fixed together through pin between two braces, and the centre is left and can be held the folding room of blade.

Said control be combined to form a cavity that is used to spur control after the handle of a knife tail end is connected.

Said the utility model blades open is during to serviceable condition, because control fixed blade on the recess that under the effect of spring cross bar is propped up to withstand on blade to be provided with has effectively avoided stressed the turning back of blade to injure user's phenomenon.

The above-mentioned optimum implementation that is merely the utility model is not that the utility model is done any pro forma restriction; All technical staff who is familiar with the present technique field, in not breaking away from the utility model technical scheme scope, the technology contents that is disclosed more than capable of using, and a little change of making are modified and are developed etc., all still belong in the scope of technical scheme of the utility model.

The utility model compared with prior art has following advantage:

Because the utility model adopts said structure, control is connected the back and forms integral handle with handle of a knife, and this control is the part of handle; Promptly be that handle is again a locking mechanism, have the dual-use function effect, saved the handle portion manufactured materials greatly; It is simple in structure, and is fashionable, convenient and practical.

Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, accompanying drawing 6; A kind of new type foldable pocket knife; Comprise handle of a knife 1 and be connected on the handle of a knife and folding blade 2; Said handle of a knife tail end is provided with the control 3 that is used for fixing blade, and an end of this control flexibly connects through screw and handle of a knife tail end, and the other end is provided with cross bar 4 and contacts with the recess 5 that the blade root is provided with.

Saidly be provided with the spring 6 that offers the required elastic force of control at handle of a knife and control junction, this spring is fixed as central point with fixture 7 activities, and an end is buckled on first pin 8 that handle of a knife is provided with, and the other end is buckled on second pin 9 that control is provided with.

Said spring is a torsionspring.

Said blade root is provided with supplies with the groove position 10 that cross bar 4 slides.

Said control 3 is made up of two identical and crooked braces of size, is fixed together through pin between two braces, and the centre is left and can be held the folding room 11 of blade.

Said control be combined to form a cavity 12 that is used to spur control after the handle of a knife tail end is connected.

The general workflow of the utility model will be described below:

When needs use the utility model; At first the blade 2 with accompanying drawing 4 states opens to accompanying drawing 2 states; The utility model need pass through following steps when blades open to accompanying drawing 2 states; Like accompanying drawing 4 when starting blade 2 rotations, the cross bar 4 that is buckled in groove position 10 at the inner end of groove position after 180 degree are slided in the groove position, because 4 of cross bars that have the thrust of spring 6 that control 3 ends are provided with withstand on fixed blade on the recess 5 that blade 2 roots are provided with; Like accompanying drawing 2, this moment, the utility model was in serviceable condition; In the time need not using the utility model; At first pass the cavity 12 of accompanying drawing 1 state with forefinger; Adopt middle finger, the third finger, little finger of toe to clamp handle of a knife; Utilize mother to refer to withstand on the handle of a knife 1 (being the handle of a knife of cross bar 4 fronts) then and control 3 is pulled out a cross bar 4 that withstands on the recess 5 is left, again the cutting edge of blade 2 is folded in the room 11 that control 3 is provided with, when blade 2 is folded in the handle of a knife fully; Because cross bar 4 fixed blade 2 on the inner end that is buckled in groove position 10 under the effect of spring 6, avoided when not using the utility model blade 2 to open effectively and injured use phenomenon all.
