Summary of the invention
Technical problem to be solved in the utility model is to provide a kind ofly cuts finger-worn type thread cutter that is reliable, easy to operate and comfortable wearing.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of finger-worn type thread cutter, comprise finger ring body, the peripheral part of described finger ring body is provided with for treating the sleeve configuration notch that trimming slips into, described finger ring body forms overhanging portion, main part and Cutting platform, described overhanging portion is positioned at the top of Cutting platform, the initiating terminal of described sleeve configuration notch is positioned on finger ring body peripheral face, the end of described sleeve configuration notch is closed state, blade moving up and down is provided with in the upper part space of sleeve configuration notch, there is between described blade and Cutting platform the gap holding and treat trimming.
Described sleeve configuration notch is arranged on the upper part of finger ring body, and at least most of region of described sleeve configuration notch is horizontal distribution.Rope yarn laterally slips in sleeve configuration notch, for blade cuts.
The head position of described sleeve configuration notch is bending, and the initiating terminal of this head position is higher than the tail end of this sweep.Easily rope yarn can be slipped into the inside of sleeve configuration notch, and rope yarn is not easy to skid off in sleeve configuration notch.
Described blade is arranged on the downside of overhanging portion, and described overhanging portion is made up of elastomeric material, and the overhanging portion described in pressing can make overhanging portion move down together with described blade.Other parts of overhanging portion and finger ring body adopt unlike material, and overhanging portion is made up of plastics elastomeric material, and pressing overhanging portion can make blade move down to cut rope yarn.After external force is eliminated, overhanging portion is reducible in original state, and its structure is reliable, and operates very convenient.
Described overhanging portion is independent of the main part of finger ring body, described blade is arranged on the downside of overhanging portion, described overhanging portion is coupling in described main part, described main part is provided with the first magnetic patch, described overhanging portion is provided with the second magnetic patch, the first described magnetic patch and the second magnetic patch composition switch module, under the first magnetic patch and the second magnetic patch attracting state, switch module is positioned at the top of pivoted connection end.Pressed by external force overhanging portion, makes the first magnetic patch be separated with the second magnetic patch, and overhanging portion moves down and impels blade to move down, and after cutting, pulls overhanging portion, and blade relies on magnet assembly to be fixed on the body of finger ring.
Described finger ring body is provided with elasticity pressing mechanism, and described blade is arranged on elasticity pressing mechanism.Arrange independently elasticity pressing mechanism to realize the movement of blade.
Described elasticity pressing mechanism comprises spring and pressing plate, described main part is provided with spring base, described springs sit is in spring base, rear end and the described spring of described pressing plate are fixed, described blade is arranged on the front end of pressing plate, be provided with cavity in described overhanging portion, described blade is positioned at described cavity.Blade is hidden in the cavity of overhanging portion, is not easy to get rusty, and safer, can not accidentally injure finger.
Described spring base is positioned at one end of main part, and the bottom, one end of described pressing plate is provided with guide housing, and it is outside that described guide housing is enclosed within described spring, and described guide housing can stretch in described spring base.It can ensure the reliability of elasticity pressing mechanism.
Described Cutting platform is provided with the groove be absorbed in for described blade.Blade is avoided to scratch Cutting platform, simultaneously also more reliable to the cutting of rope yarn.
Compared with prior art, advantage of the present invention to treat that trimming slips in the sleeve configuration notch of finger ring, and be positioned on Cutting platform, line can cut off by moving blade, overhanging portion the shape that finger ring can be made still to have finger ring is in appearance set, blade is not exposed, eliminates safe hidden trouble.The utility model cutting is reliable, operates also very convenient, comfortable wearing.
