Abstract

The invention discloses a pair of iron scissors with three handles and relates to the technical field of manually-operated metal shearing devices. The pair of iron scissors with three handles comprises a lower scissor head provided with a cutting edge, an upper scissor head provided with a cutting edge, a fixed handle and a movable handle, wherein the head portion of the fixed handle is divided into a lower end, a middle end and an upper end, the lower scissor head is fixed to the lower end of the fixed handle, one end of the lower scissor head is hinged to the middle end of the fixed handle, the other end of the lower scissor head is hinged to the movable end of the movable handle, and the rotating end of the movable handle is hinged to the upper end of the fixed handle. The tail portion of the fixed handle is divided into an upper handle and a lower handle. The problem that in the prior art, a sheared object curls, the hands holding the handles are in contact with the ground and accordingly operation is influenced can be solved.

Description

Three hands are tinsmith snips

Technical field

The present invention relates to metal sheet slitting equipment manufacturing technology field hand-manipulated, especially a kind of instrument of shear foil.

Background technology

Tinsmith snips are a kind of conventional hardware & tools, be mainly used to shear iron sheet, stainless steel sheet| etc., be widely used in the every field in daily life, conventional tinsmith snips relatively simple for structure, primarily of a pair caliper composition, two calipers are connected by middle cheek axle bolt, and, usually caliper part more than cheek axle bolt is called body of tool bit, the caliper part below cheek axle bolt is called handle body, and left and right two body of tool bit are provided with the cutting edge that energy is engaged; During use, operator first holds left and right two handle bodies, opens body of tool bit, is placed on by object to be sheared between two body of tool bit, then firmly closes up two handle bodies, two body of tool bit is closed, just can reach the object of shearing; There is following shortcoming in the tinsmith snips of above-mentioned traditional structure: the iron sheet after the first, shearing is easily curling, affects subsequent job; The second, handle body only has two, during shearing work, and the hand holding handle body below easily and earth surface, affects shearing work.

Summary of the invention

The object of this invention is to provide a kind of three hands tinsmith snips, it can solve is cut thing curling and the shake hands hand of handle and earth surface in prior art and is affected the problem of operation.

In order to solve the problem, the technical solution used in the present invention is:

A kind of three hands are tinsmith snips, comprise the lower cutter head being provided with cutting edge, upper cutter head, integral cast handle and movable hand handle, the head of described integral cast handle 8 has lower fork, middle fork and upper fork, described lower cutter head is fixedly connected with the lower fork of described integral cast handle, the cutting edge end of described lower cutter head and the middle fork of described integral cast handle hinged, the tail end of described lower cutter head and the movable end of described movable hand handle hinged, the turning end of described movable hand handle be hinged on described integral cast handle on pitch; The afterbody of described integral cast handle has left-hand seat handle and assistant's handle.

In above technical scheme, further: the upper fork of described integral cast handle is provided with torque spring by rotating shaft, two terminations of described torque spring are stuck in the edge of described integral cast handle and described movable hand handle.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

1, cut the thin plate of iron sheet and so on the present invention, cut thing clip smooth, can not occur Texturized;

2, cut sheet member with the present invention, non-force hand can buttress up knob, can not affect shearing work due to hand and earth surface;

3, the present invention adopts lever principle, and structure is simple, Labor-saving safety.

Accompanying drawing explanation

Fig. 1 is that the present invention three hand is the front view of tinsmith snips.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the present invention is further described:

A kind of three hands are tinsmith snips, comprise the lower cutter head 1, the upper cutter head 2 that are provided with cutting edge, integral cast handle 8 and movable hand are 7), the head of integral cast handle 8 has lower fork, middle fork and upper fork, lower cutter head 1 is fixedly connected with the lower fork of integral cast handle 8, the cutting edge end of lower cutter head 2 and the middle fork of integral cast handle 8 hinged, the tail end of lower cutter head 2 and movable hand hinged for the movable end of 7, movable hand the turning end of 7 be hinged on integral cast handle 8 on pitch; The afterbody of integral cast handle 8 has left-hand seat 8-1 with set about 8-2; The upper fork of integral cast handle 8 is provided with torque spring 6 by rotating shaft 5, and two terminations of torque spring 6 are stuck in integral cast handle 8 and movable hand the edge of 7.

During shearing work, iron sheet is put into the cutting edge between lower cutter head 1 and upper cutter head 2, left hand buttresses up knob 8-1, and the right hand is held flexible handle 7 and exerted a force, and iron sheet is cut; During as cut longer iron sheet, 7 every actions once, left hand can pull an iron sheet toward the opposite direction sheared to the movable hand that the right hand is held, and carry out THE ADIABATIC SHEAR IN, now shearing manipulation people can withstand up knob 8-1 slightly with left knee.
