Abstract

The utility model provides a manual scissor. The manual scissor comprises two mutually hinged cutting leaves which are provided with a hand holder at one end and a blade at the other end. The utility model is characterized in that an upper scissor leaf is formed by the hinge of the blade and the knife handle through a hinge axis and a hinge part; the knife handle of the upper scissor leaf is hinged with the knife handle of a lower scissor leaf through the other hinge shaft; the knife handle of a lower scissor leaf is in mobile connection with the blade through a connection part. The utility model overcomes the shortcoming that the current scissor is not capable of cutting big and hard or thick objects due to the superposition of the cutting line and the axis line; the cutting line of the utility model separates from the axis line; by using the principle of lever mechanics, through the connection of each hinge shaft and hinge part and with less manual power, greater cutting force can be obtained without the distortion of the cut opening of the object; the utility model can cut big articles successfully without any obstruction, which saves both the time and the power; the blade of the lower scissor leaf is in mobile connection with the knife handle, so that the blade with great stress and serious abrasion is easy for the replacement without changing the other components. The manual scissor has the advantage of low cost, convenience and practicality.

Description

A kind of manual scissors

Technical field

The utility model relates to a kind of scissors, especially a kind of manual scissors.

Background technology

Existing scissors by an end band hold other end band blade two the leaf snip is hinged forms, by of the rotation of two leaf snips, can implement to shear during use to being cut thing around pin joint.This scissors can be sheared thin and soft materials such as paper, cloth easily, also can shear little and hard article, but can't shear hard and big article, as hardboard, iron plate etc.Because shear line and its axial line of existing scissors coincide, being cut thing during shearing separates along sheared edge, when being used to shear size greater than the article of scissors length, quilt is separately cut the sheared edge of thing and will then be prolonged along the scissors axial line in the process that scissors moves ahead, and sheared edge overlaps with axial line, its result who brings is: shear thin and soft during as article such as paper, clothes because its sheared edge can be out of shape thereupon, so do not influence shearing.But shear thick and firmly during,, can not be out of shape, therefore, after clipping to, just can't continue shearing greater than cutting edge length because its sheared edge can only keep straight line as article such as hardboard, metal sheet or sheet material, plastic plates.Therefore, be necessary fully existing scissors is improved.

Summary of the invention

Existing scissors brings because of shear line overlaps with its axial line in order to overcome, can't shear big and hard or thick defectives such as article, the utility model provides a kind of shear line that can make to separate with axial line, thereby can shear the manual scissors of big and hard or thick article smoothly.

The utility model is realized by following technical proposal: a kind of manual scissors, comprise that an end band holds two leaf-cuttings other end band blade and that be hinged, it is characterized in that leaf-cutting by blade and hilt by hinge with articulated elements is hinged forms, hilt is hinged by the hilt of another hinge with following leaf-cutting, and the hilt of following leaf-cutting flexibly connects by connector and blade.The shear line of scissors is separated with axial line, and pass through the connection of each hinge and articulated elements, obtain big shearing force.

The described blade tail end of going up leaf-cutting is made as lifts up end, on lift up end the end be hinged by hinge and articulated elements one end, the articulated elements other end is hinged by hinge and hilt, so that obtain big shearing force, makes the scissors can be at hard and thick article of labour-saving situation down cut comparatively.

The blade of described leaf-cutting down is movably connected on the corresponding hilt, so that change blade as required quickly and easily by attachment screw.

The described hilt tail end of leaf-cutting down places on the support stand, and this stand is by horizonal base plate, and the band folding up plate that links to each other with horizonal base plate constitutes, and can support scissors when being used to shear, so that shearing manipulation.

The utility model compared with prior art has following advantage and effect: adopt such scheme, overcome fundamentally that existing scissors causes because of shear line overlaps with its axial line, can't shear the defective of big and hard or thick article, the shear line of scissors is separated with axial line, utilize the lever mechanics principle, connection by each hinge and articulated elements, use less manual force, just can obtain bigger shearing force, and the sheared edge of being cut thing can be out of shape, and is not subjected to any obstruction, and large piece article can be sheared smoothly, laborsavingly save time again, the blade of leaf-cutting and the flexible connection of hilt under other can make stressed big, the blade of serious wear is easy to change, and remaining part then need not to change, use cost is low, and is convenient and practical.

Description of drawings

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the A-A view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.

The blade 1 of following leaf-cutting is hinged by attachment screw 14 with the blade 2 of last leaf-cutting, the blade 1 of following leaf-cutting is movably connected in down hilt 9 front ends of leaf-cutting by attachment screw 13, so that change blade 1 as required, the tail end of the blade 2 of last leaf-cutting is made as lifts up end, the end of lifting up end on being somebody's turn to do is hinged by the left end of hinge 3 with articulated elements 4, so that under the effect of articulated elements 4, make blade 2 around screw 14 swings, the right-hand member of articulated elements 4 is hinged by hilt 8 front ends of hinge 5 with last leaf-cutting, hilt 8 is hinged by hinge 6 and the connector 7 that is connected down on the leaf-cutting hilt 9, by the swing of hilt around hinge 6, make also action thereupon of articulated elements 4, drive blade 2 at last around screw 14 swings, thereby finish the shearing of

blade

2 and 1, be provided with spring 10 between last leaf-cutting hilt 8 and the following leaf-cutting hilt 9, as Fig. 1, Fig. 2, following leaf-cutting hilt 9 tail ends can place on the support stand, and support stand is by horizonal base plate 12, the band folding up plate 11 that links to each other with horizonal base plate 12 constitutes, and is cut beyond the region of objective existence half a of during shearing ₁Sheared edge behind the E line, prolong interior half a of ₂Sheared edge behind the F line, prolong, and when using support stand, cut beyond the region of objective existence half a of ₁Sheared edge prolong interior half a of along the E line and behind riser 11 upper right sides of stand ₂Sheared edge prolong along the F line and through rear flank, stand riser 11 lower-left so that finish shearing manipulation smoothly.
