Abstract

The utility model discloses a pair of tinsmith snips with three handlebars and relates to the technical field of metal shearing equipment by manual operation. The tinsmith snips with the three handlebars comprises a lower tool bit, an upper tool bit, a fixed handlebar and a movable handlebar, wherein the lower tool bit and the upper tool bit are provided with cutting edges; the head of the fixed handlebar is divided into a lower end, a middle end and an upper end; the lower tool bit is fixedly arranged at the lower end of the fixed handlebar; one end of the lower tool bit is hinged to the middle end of the fixed handlebar; the other end of the lower tool bit is hinged to the movable end of the movable handlebar; the rotating end of the movable handlebar is hinged to the upper end of the fixed handlebar; the tail part of the fixed handlebar is divided into an upper handlebar and a lower handlebar. According to the pair of tinsmith snips, which is disclosed by the utility model, the problem in the prior art that the operation is influenced due to the facts that a sheared object is curled and hands grabbing the handlebars make contact with the ground is solved.

Description

Three handgrip tinsmith snips

Technical field

The utility model relates to metal sheet slitting equipment manufacturing technology hand-manipulated field, 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, is mainly made up of a pair of caliper, and two calipers connect by middle cheek axle bolt, and, conventionally caliper part more than cheek axle bolt is called to body of tool bit, the caliper part below cheek axle bolt is called handle body, is provided with the engaged cutting edge of energy on left and right two body of tool bit; When use, operator first holds left and right two handle bodies, opens body of tool bit, and object to be sheared is placed between two body of tool bit, then firmly closes up two handle bodies, makes two body of tool bit closures, 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, when shearing work, holds the hand of handle body below and easily contacts with ground, affects shearing work.

Utility model content

The purpose of this utility model is to provide a kind of three handgrip tinsmith snips, and it can solve in prior art thing curling and the shake hands hand of handle and the problem of ground Contact Effect operation of being cut.

In order to address the above problem, the technical solution adopted in the utility model is:

A kind of three handgrip tinsmith snips, comprise and be provided with the lower cutter head of 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 are hinged, and the movable end of the tail end of described lower cutter head and described movable hand handle is hinged, the rotation end of described movable hand handle be hinged on described integral cast handle on pitch; The afterbody of described integral cast handle has handgrip and lower handgrip.

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 having adopted technique scheme, the utility model compared with prior art has following beneficial effect:

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

2, cut sheet member with the utility model, non-application of force hand can buttress up knob, can be due to hand and ground Contact Effect shearing work;

3, the utility model adopts lever principle, simple in structure, Labor-saving safety.

Brief description of the drawings

Fig. 1 is the front view of the utility model three handgrip tinsmith snips.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment is further described the utility model:

A kind of three handgrip 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 are hinged, and the tail end of lower cutter head 2 and movable hand be hinged 7 movable end, movable hand 7 rotation end be hinged on integral cast handle 8 on pitch; The afterbody of integral cast handle 8 has handgrip 8-1 and lower handgrip 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 7 edge.

When 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 carried out the application of force, and iron sheet is cut; While cutting longer iron sheet as need, 7 every actions once, left hand can pull iron sheet one time toward the opposite direction of shearing to the movable hand that the right hand is held, and carries out THE ADIABATIC SHEAR IN, and now shearing manipulation people can withstand up knob 8-1 slightly with left knee.
