Description
Technical field
The utility model belongs to cutter field, and in particular to a kind of follow-on Multifunctional folding knife.
Background technology
Existing jack knife generally is single blade jack knife, and such jack knife purposes is single, it is difficult to meets the daily life of people
Needed for work；Although Swiss Army Knife has multi-blade design, but multiple blades are essentially the multiple-grooved design for stacking arrangement, so that knife
The thickness of handle is larger, is unfavorable for daily carrying, and the Swiss Army Knife of multi-blade design does not have a latch-up structure, blade easily open and
User easily is hurt, security is relatively low.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model provides a kind of design double tool piece in single groove handle of a knife
Multifunctional folding knife, the Multifunctional folding knife handle of a knife is relatively thin, easy to carry.
To reach above-mentioned purpose, technical scheme provided by the utility model is：A kind of Multifunctional folding knife, including handle of a knife and knife
Piece, wherein, handle of a knife includes two handle of a knife pieces, and blade is articulated with one end of two handle of a knife pieces, and blade position by main axle structure
Between two handle of a knife pieces, the other end of described two handle of a knife pieces is also hinged with cutting element piece, blade by main axle structure
With cutting element piece in closed state, the position of blade and the position face of cutting element piece, and blade and cutting element piece
All around same direction Unscrew and closure.
By such scheme, one end of handle of a knife is blade, and the other end is cutting element piece, and the purposes of jack knife is various, and knife
Piece and cutting element piece in closed state, the position of blade and the position face of cutting element piece, equivalent to blade and are cut
Implement sheet shares a groove position, makes the handle of a knife of jack knife relatively thin, is convenient for carrying, and blade uses mutual not shadow with cutting element piece
Ring, it is easy to use.
Further, the both ends of above-mentioned handle of a knife are additionally provided with fixing pin, and two handle of a knife pieces are fixed at the both ends of fixing pin
Inner side, when blade and cutting element piece in the on-state, the fixing pin of the breech face and corresponding end of blade and cutting element piece

3 afterbody is respectively equipped with hole 9, and the aperture in hole 9 is more than the diameter of steel ball 811, when blade 2 and cutting element piece 3 are in closure state
Under, the exposed part of steel ball 811 can be slipped into the hole 9 of blade 2 and cutting element piece 3, so that blade 2 and cutting element piece 3 exist
It is locked together under closure state, avoids blade 2 and cutting element piece 3 from opening naturally, improves the security of jack knife.
It is further improved, the projection 81 on above-mentioned shell fragment 8 is located on the outside of the tail end of blade 2 and cutting element piece 3, and
Projection 81 and fixing pin 6 are located at the both sides of the center line of main shaft mother screw 41 respectively, when blade 2 and the past closure of cutting element piece 3
When direction rotates, the breech face of blade 2 and cutting element piece 3 can be first inconsistent with the projection 81 of corresponding end, avoids blade 2 and cuts
Implement sheet 3 is cut in open mode Natural closure, makes the use of jack knife more stable.
In the present embodiment, above-mentioned raised 81 is raised using cambered surface so that blade 2 and the stress of cutting element piece 3 are squeezed in side
Belling can produce when playing 81 and push shell fragment 8 open automatically perpendicular to the component of shell fragment 8 so that projection 81 relative can slip into shell fragment 8
Between blade 2 and cutting element piece 3.Be, when blade 2 and cutting element piece 3 in closed state, rotated toward opening direction
The hole wall in the hole 9 of blade 2 and cutting element piece 3, blade 2 and cutting element piece 3 is extruded projection 81 so that shell fragment 8 drives convex
Play 81 to push open outward, so as to which projection 81 departs from hole 9, blade 2 and cutting element piece 3 can continue Unscrew easily；When blade 2
When needing rotating closed with cutting element piece 3, the breech face of blade 2 and cutting element piece 3 is extruded projection 81 so that shell fragment 8
Projection is driven 81 to push open outward, blade 2 and cutting element piece 3 can continue rotating closed easily.
It is further improved, above-mentioned handle of a knife piece 11 opens up fluted 111 in the position fixed ends of corresponding shell fragment 8 so that
Handle of a knife piece 11 is thinning in the thickness of the position fixed ends of corresponding shell fragment 8, improves the elasticity of shell fragment 8.
Multifunctional folding knife in the present embodiment, fixing pin 6 is provided with by the both ends of handle of a knife 1, can be to blade 2 and cutting element piece
3 play stop bit effect, and be effectively prevented from blade 2 and cutting element piece 3 influences to use or damage because of excessive Unscrew or closure
Bad blade；And the shell fragment 8 on two handle of a knife pieces 11 is provided with projection 81, when blade 2 and cutting element piece 3 in closed state, it is convex
Play 81 and can slip into blade 2 and hole 9 set by cutting element piece 3 and play locking action, avoid blade 2 and cutting element piece 3 from
So open, improve the security of jack knife；When blade 2 and cutting element piece 3 rotate toward closing direction, blade 2 and cutting element
The breech face of piece 3 and the projection 81 of corresponding end are inconsistent, avoid blade 2 and cutting element piece 3 from making in open mode Natural closure
The use of jack knife is more stable.
Schematically the utility model and embodiments thereof are described above, this describes no restricted, accompanying drawing
Shown in be also one of embodiment of the present utility model, actual structure is not limited thereto.So if this area
Those of ordinary skill enlightened by it, do not depart from the utility model create objective in the case of, without creativeness design
