The mounting seat that retaining mechanism includes being fixedly connected on fixed arm, the movable alignment pin being arranged in mounting seat and be arranged between alignment pin and mounting seat for by alignment pin towards the flexible member near top, the side of lever arm pressure, lever arm outer peripheral edge side by side be provided with multiple double wedge, form the groove of insertion for stop pin between adjacent two double wedges.
Double wedge includes the pressure inclined-plane, top of the top pressure alignment pin when lever arm rotates relative to fixed arm and with detent fit to prevent the counter-rotational confined planes of lever arm.
Being provided with an installing hole in mounting seat, the cross-under of alignment pin activity is in installing hole, and flexible member is a spring being enclosed within alignment pin, and this spring is limited between alignment pin and the outboard end of installing hole.
Handle of a knife is provided with two fixed arms, between this two fixed arm, forms a gap penetrated for lever arm.
Blade and handle of a knife are fixed together by a clamping screw.
The beneficial effects of the present invention is:
Compared to existing shears, the size holding hole that handle of a knife of the present invention penetrates for finger can adjust, so that shears can adapt to the finger of different thicknesses, people are in use, it is possible to the hole that holds of shears is adjusted state the most comfortable; The angle of handle of a knife and blade can adjust simultaneously, and applicable different shearing needs.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the zoomed-in view at A place in Fig. 1;
Wherein: 10, handle of a knife; 11, fixed arm; 20, blade; 30, clamping screw; 40, lever arm; 41, double wedge; 411, top pressure inclined-plane; 412, confined planes; 50, retaining mechanism; 51, mounting seat; 52, installing hole; 53, alignment pin; 54, spring.
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
Referring to Fig. 1, shown in 2, a kind of shears for the present invention, it includes the cut cells of two hinges, wherein, each cut cells all includes blade 20 and handle of a knife 10, handle of a knife 10 and the fixing connection of blade 20, particularly, handle of a knife 10 and blade 20 adopt clamping screw 30 to be fixed together, so, the detachable of handle of a knife 10 and blade 20 can be realized, simultaneously, the pivot that clamping screw 30 can be rotationally connected as handle of a knife 10 and blade 20, when needing to adjust blade 20 relative to the angle of handle of a knife 10, unscrew clamping screw 30, blade 20 is adjusted applicable angle, screw clamping screw 30 again.
Handle of a knife 10 is provided with all curved fixed arm 11 and lever arm 40, the opening of arc both it is relative, wherein one-body molded one end with handle of a knife 10 away from blade 20 of fixed arm 11, one end of lever arm 40 is hinged on one end of fixed arm 11, the other end of fixed arm 11 is provided with for the other end of lever arm 40 is locked at retaining mechanism 50 thereon, an accommodation hole penetrated for finger is surrounded between fixed arm 11 and lever arm 40, lever arm 40 is rotated relative to fixed arm 11, adjustable holds the size in hole, after adjusting, retaining mechanism 50 is utilized to be locked on fixed arm 11 by lever arm 40. this retaining mechanism 50 particularly includes one-body molded or adopts other modes to be fixed on the mounting seat 51 on fixed arm 11, the movable alignment pin 53 being arranged in mounting seat 51, and one be arranged between alignment pin 53 and mounting seat 51 for by alignment pin 53 towards near lever arm 40 side top pressure flexible member, the outer peripheral edge of lever arm 40 side by side be provided with multiple double wedge 41, a groove inserted for alignment pin 53 is formed between two adjacent double wedges 41, when adjusting the position of lever arm 40, under the elastic stress of flexible member, alignment pin 53 is inserted in one of them groove, lever arm 40 is locked. in order to realize the self-locking of lever arm 40 and alignment pin 53, above-mentioned double wedge 41 side is set to a pressure inclined-plane, top 411, opposite side is set to a confined planes 412, wherein, pressure inclined-plane 411, top rotates outwards top pressure alignment pin 53 gradually at lever arm 40, when alignment pin 53 turns over double wedge 41 top ends, under the effect of flexible member, the end of alignment pin 53 drops into the rear side of confined planes 412, so, guarantee that lever arm 40 is only capable of one-directional rotation, in use, although lever arm 40 can reversely be pushed up pressure by finger, lever arm 40 is without rotating backward.
Mounting seat 51 has an installing hole 52, and the cross-under of alignment pin 53 activity is in installing hole 52, and flexible member is a spring 54 being enclosed within alignment pin 53, and this spring 54 is limited between the outboard end of alignment pin 53 and installing hole 52;It is of course also possible to adopt other elastomeric elements to substitute above-mentioned spring 54.
Handle of a knife 10 is provided with two fixed arms 11, a gap penetrated for lever arm 40 is formed between this two fixed arm 11, when holding, hole is less, when needing to readjust, then lever arm 40 is produced from the gap between two fixed arms 11, again rotate lever arm 40 according to predetermined adjustment direction again, make alignment pin 53 be inserted in corresponding groove.
Compared to existing shears, the size holding hole that handle of a knife of the present invention penetrates for finger can adjust, so that shears can adapt to the finger of different thicknesses, people are in use, it is possible to the hole that holds of shears is adjusted state the most comfortable; The angle of handle of a knife and blade can adjust simultaneously, and applicable different shearing needs.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within the protection domain of the claims in the present invention.
