Description

The removable Scissors without sharpening of cutting edge

The utility model relates to the cutting implement field, is the removable Scissors without sharpening of a kind of cutting edge.

As everyone knows, scissors is one of indispensable instrument in the life, and it provides the convenience of non-hard things such as the hammer-shears cut paper is opened, cloth to people.It is along with shearing increasing of number of times, and cutting edge will rust, thereby during the yo-heave-ho of " cutter grinds scissors " master worker's cordiality and pass to lanes and alleys head and alley tail.The disadvantageous reason of cutting edge is not to make of " good steel " by cutting edge normally, or the cutting edge Technology for Heating Processing is selected improper and caused.The patent No.: 91225563.3, disclosed a kind of scissors that laminar cutting edge mounts the inner surface that is fixed on haircut to society, this scissors structure design is comparatively complicated, and cutting edge and threaded disk fixture must make up through spot welding, it is convenient that the dismounting of cutting edge is owed, and also must use after grinding.

The purpose of this utility model is to provide a kind of cutting edge removable Scissors without sharpening to society, to solve cutting edge dismounting inconvenience, the problem that cutting edge need be sharpened.And make its structural design comparatively reasonable, the scissors that is easy to apply.

The design of this scissors is such: it is to offer the thin type groove that embeds for cutting edge in cutting handle, thin slice shape cutting edge embeds in this shape groove, and the upper end of cutting edge is provided with the card point, the bottom is provided with convex shoulder, be stuck in the thin type groove angle after the card point embeds, the bottom convex shoulder is fixed by screw after embedding the thin type groove.Pull down thin slice shape cutting edge and spin off screw earlier, stretch into the convex shoulder that unloads sword hole impulsion cutting edge by reinforcing bar again, cutting edge can break away from the thin type groove, thereby, implement the replacing of cutting edge (cutting edge).

The advantage of its structure is to cut can adopting injection mo(u)lding, or use the die cast metal moulding, and cutting edge directly with tool steel material processing, can adapt to than production in enormous quantities, the service life of raising scissors.

Sequence number: 1, handle is cut on a left side, and 2, left cutting edge, 3, right cutting edge, 4, the right side cuts handle, 5, nut, 6, croze, 7, screw, 8, regulate bolt, 9, the card point, 10, convex shoulder.11, unload the cutting edge hole.

Referring now to above schematic diagram, and in conjunction with the embodiments its feature is further described: the removable Scissors without sharpening of cutting edge, by a left side cut 1, left cutting edge 2, cut 4 on right cutting edge 3, the right side, nut 5, screw 7, adjusting bolt 8 are formed, and the thin type groove that is provided with for left cutting edge 2 arrangements is cut on a left side to 1, and left cutting edge 2 embeds in the thin type grooves, after the card point 9 of its upper end embeds is to be stuck in the thin type groove angle, and the convex shoulder 10 of bottom is fixed by screw 7 after embedding the thin type groove; The thin type groove that is provided with for right cutting edge 3 arrangements is cut on the right side to 4, and right cutting edge 3 embeds in the identical thin type groove, and the card point 9 of its upper end also is to snap in the thin type groove angle, and the convex shoulder 10 of bottom is also fixed by screw 7 after embedding the thin type grooves.On cutting 1 on a left side nut 5 is set, this nut is supporting with adjusting bolt 8, and the cutting edge of regulating left and right cutting edge is in suitable gap; Offer and regulate the croze 6 that bolt 8 is complementary on cutting 4 on the right side.Croze 6 is vertical setting, and it slightly is wider than the head of regulating bolt 8.

Embodiment: with this scissors of die cast metal is example, and mould is divided into left and right cutting each pair, the embryo clamping of making of cutting is placed on the milling machine, cutting edge embed this face mill out size slightly wide, slightly be longer than the thin type groove of cutting edge.Thereafter, cutting attacking the system screw thread of the fixed position of convex shoulder one side, so that supporting during screw-driving.Left and right cutting edge is made with instrument steel matter, and the thin type groove of packing into after putting the first edge on a knife or a pair of scissors gets final product.The convex shoulder of installing is by jail that screw pushes up, left and right cut on all offer and unload the cutting edge hole.When unscrewing screw, towards this hole, just cutting edge can be taken out with fine steel rib.Left and right cutting except that metal material is made can also be used nonmetallic materials manufacturings such as plastics, rubber, bakelite.This Scissors without sharpening is to sharpen cutting edge, blunt promptly changes, and can effectively increase work efficiency and service life, and certain application value is arranged.
