Abstract

The utility model belongs to a metal shearing tool, particularly a pair of strong scissor. The utility model adopts a lever planet wheel mechanism which is designed based on the existing pair of ordinary scissors, namely, the front end of a handle of the left scissor (or the right scissor) is provided with a small fan-shaped gear wheel of the size corresponding to that of a planet wheel, and the middle point of the right scissor (or the left scissor) is provided with a big fan-shaped gear wheel of the size corresponding to that of a sun wheel. The utility model has the advantages of shearing labor saving, high efficiency, compact structure, and easy processing and manufacture. The shearing force of the utility model is 5-15 times greater than that of the ordinary pair of scissors. The utility model is a pair of strong scissors, which is worth popularization.

Description

Strong metal-shearing device

The utility model belongs to the metal sheet slitting instrument, especially a kind of Strong scissors.

Present industrial all departments need the industry of manual processing and manufacturing product and parts, as panel beating, pincers worker etc., when shearing the metal sheet material, generally all use common scissors (or claiming snips), can only shear steel plate below 0.75 millimeter as 320 millimeters common scissors, and it is gruelling, when steel plate thickness reached 1 millimeter, this common scissors then can't be cut off at all.

The utility model improves at the problem of above-mentioned existence, design a kind of simple in structure, shearing force is big, easy to use, labour-saving Strong scissors.

The utility model is achieved by following manner: a kind of structure, cut and the right Strong scissors of formation of cutting on the left side that shape and size are identical, cut on its left side and right front portion of cutting is handgrip for the cutting edge rear portion and by rivet a left side is cut that to cut hinged with the right side be an integral body, feature of the present utility model be a left side is cut and right cutting in one be designed to two body structures and (can select a left side to cut here, also can select the right side to cut, as select a left side to cut), it comprises handgrip two parts of scissors head and bar portion, the handgrip front end of its king-rod portion is provided with the little sector gear that is equivalent to planetary gear, and cut on a left side and right cutting in another in the middle of the place be provided with the big sector gear that is equivalent to sun gear (said another be meant as the front as selecting a left side to cut, here another refers to that the right side cuts), itself and aforementioned little sector gear mesh, and cut on a left side, and cut with the right side can be hinged by connecting rod and rivet, it is hinged to be that the end of connecting rod and the right side are cut by rivet, and the front end place of the handgrip of the bar portion that cut on the other end of connecting rod and a left side is hinged by rivet.The little sector gear that cut on an above-mentioned said left side can be a 3-5 tooth, it also can be 5 more than the tooth, the big sector teeth at place can lack 1-2 than little sector teeth in the middle of cut on the right side, the Strong scissors of common centering ting model, its little sector teeth number is 3 or 4, big sector teeth number is 2 or 3, and to the Strong scissors of big model, its large and small sector teeth number can correspondingly increase.The operation principle of this Strong scissors is to adopt lever and planetary wheeling mechanism, cut with the right side when the left side of Strong scissors and to cut when being in open configuration, cut with wherein a left side under the hand, at this moment the left little sector gear of cutting the handgrip front end of bar portion is cut center around the right side big sector gear rotates, at this moment the left scissors head of cutting makes it cut merging to the right by the leverage of connecting rod, thereby cuts off steel plate.

The utility model is compared with prior art, has characteristics such as compact conformation, big, the easy processing and manufacturing of shearing force, applied range.

Fig. 1 is an overall structure schematic diagram of the present utility model.

Among the figure: cut on scissors head, 3 left sides that cut on 1 right side, cut on 2 left sides, 4 rivets, 5 connecting rods, 6 rivets, 7 right sides are cut the handgrip of bar portion, handgrip, 9 little sector gears, the 10 big sector gears that bar portion is cut on 8 left sides.

Most preferred embodiment of the present utility model, as shown in Figure 1.A kind of structure, the left side that shape and size are identical cuts 3 and right 1 Strong scissors that constitutes of cutting, its left side cut 3 and right cut 1 front portion for the cutting edge rear portion be handgrip 7 and 8 and by rivet with a left side cut 3 and the right side cut 1 hinged be an integral body, feature of the present utility model be with a left side cut 3 and right of cutting in 1 be designed to two body structures and (can select a left side to cut 3 here, the also optional right side cuts 1, as select a left side to cut 3), it comprises handgrip 8 two parts of scissors head 2 and bar portion, handgrip 8 front ends of its king-rod portion are provided with the little sector gear 9 that is equivalent to planetary gear, and a left side cut 3 and right cut another (refer to the right side cut 1) in 1 in the middle of the place be provided with the big sector gear 10 that is equivalent to sun gear, itself and aforesaid little sector gear 9 mesh, and a left side cut 3 and the right side cut 1 can be hinged by connecting rod 5 and rivet 4 and 6, it is 1 hinged by rivet 4 to be that the end of connecting rod 5 and the right side are cut, the other end of connecting rod 5 is hinged by rivet 6 with the handgrip 8 that 3 bar portion is cut on a left side, the little sector gear 9 that cut on 3 on an above-mentioned said left side can be a 3-5 tooth, it also can be 5 more than the tooth, the tooth that the big sector gear 10 at place in the middle of 1 is cut on the right side can lack 1-2 than the tooth of little sector gear 9, the Strong scissors of common centering ting model, the number of teeth of its little sector gear 9 is 3 or 4, the number of teeth of big sector gear 10 is 2 or 3, to the Strong scissors of big model, its big or small sector gear 10 and 9 the number of teeth can correspondingly increase.The utility model can manufacture and design large, medium and small various model in a word, to adapt to the needs that satisfy industry and social all departments.
