Abstract

The utility model belongs to a hand tool, particularly a pair of shears which is used for shearing a metallic line material. The utility model comprises a cutter head, a rivet shaft, an upper cutter holder and a lower cutter holder. The utility model is characterized in that a cutter blade of a connecting plate and a positioning support of the connecting plate are arranged at a position which corresponds to the cutter head; the cutter head, the cutter blade of the connecting plate and the positioning support of the connecting plate are connected with each other by the rivet shaft in the way of movable fit. The utility model aims to solve the problems that the operating force of scissors is big and the scissors are easily damaged. The utility model has the advantages of long service life, small operating force and low cost. When the utility model is used, the HRC45 metal line material can be sheared. The utility model is widely used for the field of construction, metal products, etc.

Description

The matrix olecranon shear

The utility model relates to a kind of hand-operated tools of shearing metal wire rod.

At present, industrial enterprises such as building, metallic article are used to shear the hand-operated tools of metal wire rod both at home and abroad, and appearance structure and shearing mechanism all are identical, are both the acute angle that utilizes blade and are squeezed into the section of being cut object up and down, to reach the purpose that extruding is broken.Adopt the principle of extruding to cause to cut off resistance very big, use and not only require great effort but also inconvenient, especially during work high above the ground, the excessive danger that causes easily of exerting oneself.Because sharp keen cutting edge damages easily, service life is short, makes usage charges expenses of labour power, therefore causes great waste.

At problem set forth above, the purpose of this utility model is exactly to change the extrusion stretching principle into shearing mechanism in order to provide a kind of novelty simple in structure, technology reasonable, reduces and cuts off resistance, uses laborsaving, the matrix olecranon shear in raising service life.

The utility model is achieved through the following technical solutions:

The matrix olecranon shear, it includes cutter head, connecting plate blade, rivet shaft, cushion block, left handle, right handles, regulating block and a plurality of rivet, connecting plate blade and connecting plate positioning supports are fastened on the both sides of cushion block with rivet, make cutting edge form a groove on cross section, cutter head is just falling in the groove on last cutter head and cutting edge are pinched under the tight state; Last cutter head and connecting plate blade, connecting plate positioning supports fuse movingly with rivet shaft, and the last transverse plane of connecting plate blade is that cutting edge and last cutter edge face are in same plane, and transverse plane is a positioning supports on the connecting plate positioning supports.

Because tension stress the utility model has the advantages that compared with prior art much larger than shear stress in the mechanics, have long service life, characteristics that operating physical force is little, save labor, easy to operate, improve shear stiffness, can shear very hard metal wire rod; The cost cost is low, can adopt leftover bits to make; Applied range can be widely used in the fields such as building, metallic article.

Description of drawings is as follows:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the A-A profile of the utility model cutter head.

Below in conjunction with accompanying drawing the utility model is specifically described:

Olecranon cutter head 1, connecting plate blade 2 and connecting plate support 3 usefulness rivet shafts, 5 riveteds and are connected as a single entity, and accompany a cushion block 4 in the middle of connecting plate blade 2 and the connecting plate positioning supports 3, and riveting tightly with rivet 6 becomes one admittedly; The last transverse plane of connecting plate blade 2 is that the cutting edge face of cutting edge and last cutter head 1 is in same plane, and transverse plane is a positioning supports on the connecting plate positioning supports 3.Connecting plate blade 2 and connecting plate positioning supports 3 usefulness rivet 6 are fastened on the both sides of cushion block 4, make cutting edge form a groove on cross section, pinch tight state at last cutter head 1 with cutting edge and fall in the groove; Last cutter head 1 fuses movingly with connecting plate blade 2, connecting plate positioning supports 3 usefulness rivet shafts 5.In left handle 7 upper ends in bulge fork handle and right handles 8 upper ends bulge fork handle plug, middle fuse movingly with rivet shaft 10; Insert in the left handle 7 upper end fork handles lower end of cushion block 4 in the middle of the connecting plate, and insert in the fork handle of right handles upper end last cutter head 1 lower end, fuses movingly with rivet shaft; A regulating block 11 is installed on the left handle 7, on regulating block 11, is provided with the adjustment screw 12 that to regulate cutter head 1 and blade 2 positions, be used to regulate the cutting edge gap.Left handle 7 upper end fork handles and cushion block 4 lower ends are riveted movingly with rivet shaft 9 and are connected as a single entity, and right handles 8 upper end fork handles and olecranon cutter head 1 lower end are riveted movingly with rivet shaft and be connected as a single entity.

The utility model in use, earlier two handles are opened, cutter head 1 opens with blade 2 thereupon, to be cut thing and be placed between two blades, handle 7,8 is inwardly afterburning, contracts in the cutting edge, cut thing this moment except that load is on cutting edge, carry on a shoulder pole simultaneously on connecting plate positioning supports 3, to guarantee that being cut the stable of thing does not tilt, and is cut thing and can cut off when continuing reinforcing.Because the diameter difference of being cut thing, thus in advance with adjustment screw 12 up and down the blade gap adjustment be in the optimum position in suitable position to guarantee handle.
