Abstract

The utility model discloses a pair of asymmetric pressure scissors which are composed of an upper and a lower handles 6, 5, an upper and a lower shearing rods 8, 9, and an upper and a lower shearing handles 1, 2., wherein, the inner side of the lower end of the lower shearing rod 9 is connected with the inner side of the back part of the lower shearing handle 2, and the upper end of the lower shearing rod 9 is connected with the upper handle 6; the inner side of the lower end of the lower shearing rod 9 is connected to a concave mouth of the lower shearing handle 2, and the inner side of the lower end of the upper shearing rod 8 is connected with the back part of the upper end of the upper shearing handle 1; the upper end of the upper shearing rod 8 is connected with the lower handle 5, and the upper and the lower shearing handles 1, 2 are connected with each other by a pin axle 7. The utility model can shear metal and non-metal products of which the thickness is larger than 0.5 mm, and can shear curve and arc products. With the advantages of free shearing, time saving and labor saving, the utility model is a new pair of scissors product for replacing old scissors.

Description

The non-symmetric pressure scissors

The utility model belongs to life, the tool of production, particularly a kind of non-symmetric pressure scissors that is used for cutting metal, on-metallic article.

At present, the manual scissors that uses up and down handle, cut bar, cut handle on same plane, handle is by the interactive scissors of opening of finger during shearing, shear goods by cutting edge, because do not have discharge gate cutting between bar and the cutting edge, make the goods and following handle phase resistance that are sheared, the quilt of often having to is separately cut thing, when being sheared goods＞0.5m thickness, common scissors can not be sheared; During in addition for shearing curve, circular arc goods, can not gain advantage from both sides, shear freely, waste material is wasted time and energy, if long-time firmly shearing causes the compressing finger, influences blood circulation.

The purpose of this utility model is to overcome above technical deficiency, and a kind of non-symmetric pressure scissors of laborsaving, good discharge is provided.

Task of the present utility model is, the non-symmetric pressure scissors by upper and lower handle, upper and lowerly cut bar, the upper and lower handle of cutting is formed, the inboard lower scissor handle posterior medial upper end that connects, lower scissor rod lower end connects up knob, the inboard connection in the lower scissor handle recess in the lower scissor rod lower end, the inboard upper rear that connects upper shearing handle in the upper scissor rod lower end of installing, the upper scissor rod upper end connects handle down, and the upper and lower handle of cutting is connected by bearing pin.

The non-symmetric pressure scissors tool has following characteristics, and its leader, to cut bar, cut handle be last pressure lever construction, increase kinetic moment, laborsaving, increase work efficiency; It two is being cut bar and is cutting handle institute junction and have discharge gate, is convenient to cut＞slab of 0.5mm; Its three since handle on discharge gate, shearing curve, circular arc goods, left and right cutting across sheared freely.

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 shows non-symmetric pressure scissors front view.

The A-A profile of Fig. 2 diagrammatic sketch 1.

The B-B profile of Fig. 3 diagrammatic sketch 1.

The vertical view of Fig. 4 diagrammatic sketch 1

Fig. 5 shows non-symmetric pressure scissors work sheet.

Among the figure, the 1-upper shearing handle; The 2-lower scissor handle; Discharge gate under the 3-; The last discharge gate of 4-; Handle under the 5-; The 6-up knob; The 7-bearing pin; The 8-upper scissor rod; The 9-lower scissor rod

With reference to accompanying drawing 1-4, the non-symmetric pressure scissors by upper and

lower handle

6,5, upper and lowerly cut bar 8,9, the upper and lower handle 1,2 of cutting is formed, the inboard lower scissor handle 2 posterior medials upper end that connects, lower scissor rod 9 lower ends connects up knob 6, the inboard connection in lower scissor handle 2 recesses in lower scissor rod 9 lower ends, the inboard upper rear that connects upper shearing handle 1 in upper scissor rod 8 lower ends of installing, upper scissor rod 8 upper ends connect handle 5 down, and last lower scissor handle 1,2 is connected by bearing pin 7.The upper scissor rod 9 that up knob 6 connects is a lever construction with lower scissor handle 2, and not in same plane, the upper scissor rod 8 that following handle 5 connects is a lever construction with upper shearing handle 1, not in same plane.Lower scissor handle 2 tops and upper scissor rod 9 inboards have discharge gate 4, and last discharge gate 4 is the second order opening.Upper shearing handle 1 cutting edge bottom has down discharge gate 3 to tangent line place, upper scissor rod 9 lower end, and the cutting edge of upper shearing handle 1 tilts.

With reference to accompanying drawing 5, when the non-symmetric pressure scissors used, finger pierced into upper and

lower handle

6,5, opens upper and

lower handle

6,5, and upper and lower handle 1,2 cutting edges of cutting are opened, and sends into the article that are sheared, under the effect of last pressure lever construction, and the scissor cut article.

The non-symmetric pressure scissors can be sheared＞the 0.5mm metal, on-metallic article, but shearing curve, circular arc goods shear freely, laborsaving saving time is a kind of scissors goods of update.

Claims

One kind by upper and lower handle 6,5, upper and lowerly cut bar bar 8,9, upper and lowerly cut the non-symmetric pressure scissors that handle 1,2 is formed, it is characterized in that the inboard lower scissor handle 2 posterior medials upper end that connects, lower scissor rod 9 lower ends connects up knob 6, the inboard connection in lower scissor handle 2 recesses in lower scissor rod 9 lower ends, the inboard upper rear that connects upper shearing handle 1 in upper scissor rod 8 lower ends of installing, upper scissor rod 8 upper ends connect handle 5 down, and the upper and lower handle 1,2 of cutting is connected by bearing pin 7.
