Abstract
The utility model discloses a kind of finger ring type thread cutter, comprise finger ring, the outer peripheral face of finger ring is fixedly installed ledger-plate, the outer peripheral face of finger ring is provided with a movable blades, the blade of ledger-plate is towards deviating from finger ring center, movable blades and ledger-plate form shearing component jointly, and its advantage is put on ledger-plate when rope yarn to be cut, and movable blades and ledger-plate form shearing component and cut off by rope yarn.Due to movable blades and ledger-plate acting in conjunction, though blade a little blunt point also rope yarn successfully can be cut off, the Reliability comparotive of shearing is good.The utility model height is on the whole smaller, comfortable wearing, and to operate more convenient simultaneously.
Description
Technical field
The utility model relates to a kind of thread cutter, particularly relates to a kind of finger ring type thread cutter.
Background technology
Shop-assistant in shop, the workman in workshop or housewife need to use thread cutter, China Patent No. be 89205010.1 utility model disclose finger ring shape cutting knife, its primary structure has finger ring body, finger ring body projection, be processed with groove studs with V-arrangement cutting blade, shop-assistant brings finger ring type cutter can cut plastic ties, the band of dress article conveniently, finger can not be scratched, clothes, practical safe ready.China Patent No. be 201320769801.5 utility model disclose a kind of ring paper knife, it comprises ring, cutter shell, the ring of ring is connected with rectangle cutter shell, the upper end open of cutter shell, opening part is connected with seal cover, blade is provided with in cutter shell, blade lower end is provided with baffle plate, one end of baffle plate is connected with push button, push button causes outside cutter shell by the rectangular channel on cutter shell, the long limit of rectangular channel and blade parallel, elastomeric material is filled with in cutter shell, it can be worn on finger easily, more convenient fixing, blade can be slided by push button in cutter shell, in use blade is withdrawn, receive in cutter shell time no, finger or other article are hurt when avoiding no.The shortcoming of finger ring shape cutting knife is: V-arrangement cutter are that the mode slipping over one side blade by rope yarn is cut it, when cutter a little rust time, rope band cannot be cut off easily.The structure of ring paper knife is too complicated, and the height of cutting part is too high, and it is not too comfortable not too convenient with operation to wear.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind ofly cuts finger ring type thread cutter that is reliable, easy to operate and comfortable wearing.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of finger ring type thread cutter, comprise finger ring, the outer peripheral face of described finger ring is fixedly installed ledger-plate, the outer peripheral face of described finger ring is provided with a movable blades, the blade of described ledger-plate is towards deviating from finger ring center, and described movable blades and described ledger-plate form shearing component jointly.
The outer peripheral face of described finger ring has a mounting platform, described ledger-plate is fixedly mounted on described mounting platform, the first end of described mounting platform is connected with pressing component, described movable blades is arranged on the inner side of pressing component, and the blade of described movable blades is towards the blade of ledger-plate.Pressing component is operated, after movable blades is pressed down, forms shearing component with ledger-plate.Relatively simple for structure, after pressing component presses down, blade is just hidden in inside, safer.
Described mounting platform is positioned on the top outer peripheral face of finger ring.When finger ring is worn on forefinger, shearing component is positioned at the side of forefinger, realizes one-handed performance, thus convenient.
Second end of described mounting platform is provided with the first magnetic patch, and the first described magnetic patch is positioned at the side of ledger-plate, is provided with the second magnetic patch below the free end of described pressing component, and the first described magnetic patch and the second magnetic patch cooperatively interact.After pressing component presses down, magnetic part is utilized to be fixed together with movable blades by pressing component, safer in structure, and volume is smaller.
The first end of described mounting platform is provided with the seat that is coupling, the described seat that is coupling is provided with limiting section and outer convex arc surface, the first end of described pressing component is provided with interior concaved circular cambered surface, described outer convex arc surface and described interior concaved circular cambered surface cooperatively interact, and described limiting section is stuck in the center of described interior concaved circular cambered surface.Limiting section is utilized to lift amplitude to what limit pressing part, more convenient to operate, make blade safer simultaneously.
The inner side of described pressing component is provided with the first groove holding ledger-plate, described mounting platform is provided with the second groove holding movable blades.After pressing component presses down, two blades are hidden in respective groove respectively.
After described pressing component presses down, the medial surface of described pressing component and the upper surface of mounting platform fit tightly.After pressing component presses down, the existence having blade do not seen by finger ring in overall appearance, and design comparison is reasonable, has good aesthetic appearance.
The free end of described pressing component is provided with spanner position, and the sectional area at described spanner position is less than the sectional area of the main part of pressing component, and the second described magnetic patch is arranged on the inner side at spanner position.Wrench portion is smaller and more exquisite, operates more convenient, and simultaneously the second magnetic patch is arranged on the inner side at spanner position, can make pressing component to lift power less, the stability simultaneously after pressing is better.
Generally horizontal of the upper surface of described pressing component, after pressing component presses down, the pivoted connection end of pressing component and the adjacent edge circular arc smooth transition of finger ring.Finger ring structure comparison is on the whole compact, small volume, profile compares simultaneously and has aesthetic feeling.
Described ledger-plate and movable blades are all the rectangular blade of strip, and ledger-plate length accounts for more than 1/2 of mounting platform length, and described movable blades length accounts for more than 1/2 of mounting platform length.Make full use of the length of upper mounting plate, make after increase shearing component, structure is still compact, small volume, comfortable wearing.
Compared with prior art, the utility model has the advantages that when rope yarn to be cut is put on ledger-plate, movable blades and ledger-plate form shearing component and are cut off by rope yarn.Due to movable blades and ledger-plate acting in conjunction, though blade a little blunt point also rope yarn successfully can be cut off, the Reliability comparotive of shearing is good.The utility model height is on the whole smaller, comfortable wearing, and to operate more convenient simultaneously.
