Abstract

The utility model relates to a pair of novel scissors, which is composed of two pieces of blades and handles. Rivets are used as connecting fulcrums, and the blades and the handles are connected into integration. The utility model changes the connection mode that the handles and the blades of the existing scissors are connected into a straight line. The handles and the blades have certain angles in the design of the utility model, so that the handles are always above the materials being cut in the tailoring process. The utility model overcome the deficiencies that when the existing scissors are used to cut multilayer materials or hard materials such as thin iron sheets, etc., the materials being cut have large deformation and the materials with cut length larger than the point length of blades can not be cut. The utility model can be widely used in the occasions such as sewing, sheet material cutting, etc.

Description

Shears

The utility model relates to a kind of cutting cloth that is used for, the scissors of paper or sheet metal.

Scissors in the past, blade and handle generally all point-blank, and handle mostly is semicircle greatly, in the cutting process, the hand of operation and blade generally will be in line and advance.In case when running into cutting multilayer cloth,, often will raise cloth because handle is too big, the cloth otch is uneven to making, and causes error, especially during hard material such as cutting sheet iron, after the incision length of being cut material surpassed blade cutting edge length, cutting just can't be carried out.

The purpose of this utility model is to provide a kind of in the cutting process, and the cutting edge of blade is cut material with quilt and become parastate to advance substantially, and handle is the novel scissors above quilt is cut material all the time.

The purpose of this utility model is to realize like this, on the basis of conventional scissors, with two blades of scissors and a slice in the handle, make handle and blade around being connected fulcrum to edge direction, bend to the angle of 90～120 degree, with the handle of another sheet blade of scissors direction to the knife back, bend to 120～160 ° angle around connecting fulcrum, the cutting edge with two blades connects into novel scissors by screw or rivet relatively on fulcrum then.

Advantage of the present utility model:

1, simple in structure, easy to manufacture, cost and common scissors are more or less the same.

2, because a slice cutting edge of scissors moves in the parallel beneath of being cut material all the time, make it when cutting out multilayer material, can guarantee the precision of each layer.

3, since the handle of scissors in the sanction process all the time cut material above, can make that to be cut material deformation little, particularly when cutting otch during above the hard material of blade cutting edge length, becoming, it is feasible to make things convenient for.

Introduce an embodiment below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.With reference to accompanying drawing 1, earlier handle (1) and blade (2) are integral with steel plate punching press or forging, in the centre of handle (1) with blade (2) junction, process a through hole (4), when punching press or forging, make a handle (1) become the flexibility of 90～120 degree with sword (3) direction of blade, make another handle (1) and blade (2) become the flexibility of 120～160 degree to knife back direction, cutting edge with two blades is relative at last, pass separately through hole (4) with screw or rivet, make it tighten up the cost scissors.

Claims

1, a kind of novel scissors comprises two handles, blade and cutting edge thereof, connect into an integral body by rivet or screw as connecting fulcrum, it is characterized in that in two handle blades of scissors that handle has the flexibility of 90～120 degree to the direction of blade cutting edge around connecting fulcrum; The knife back direction of another handle and blade has the flexibility of 120～160 degree around connecting fulcrum.
