Abstract
The utility model discloses clamping and twisting shearing pincers in the hardware tools, which mainly comprise a pair of pincer heads and a pair of pincer handles, wherein the pin shafts of the pair of pincer heads are articulated; the upper ends of the two pincer handles are articulated by the pin shaft; the lower parts of the two pincer heads are respectively articulated onto the pincer handles through the rivets. In the pincer with the structure, the force acting on the pincer handles is conveyed to the two pincer heads through the two rivets and the two pin shafts. Through the function similar to twice leverage, the force on the pincer head is increased obviously, thereby attaining objective of labor saving during shearing or twisting operation.
Description
Technical field
The utility model relates to the hardware ﹠ tools field, and the folder that refers more particularly to is wherein turned round cutting nipper.
Background technology
Hardware ﹠ tools is widely used in all trades and professions, it is one of classification the most basic in the hardware ﹠ tools that folder is turned round cutting nipper, it mainly comprises cutting pliers, nipper plier, diagonal cutting nippers or the like, their structure is quite similar, mainly comprise: a pair of binding clip and a pair of pincers handle, and common left binding clip links into an integrated entity, forms a caliper with right pincers handle; Right binding clip links into an integrated entity, forms another caliper with left side pincers handle; These two calipers are arranged in a crossed manner and be movably hinged mutually by the binding clip bearing pin.The using method that the folder of above-mentioned traditional structure is turned round cutting nipper is: a pair of pincers handle of operator grasps makes binding clip realize clamping, reverse or function such as shearing by being applied to the power of pincers on the handle.It is relatively simple for structure that this folder is turned round cutting nipper, but in use have following shortcoming: must apply bigger power to the pincers handle when one, using, thereby relatively require great effort; Two, this pliers can not be got back to previous position after finishing an operation automatically, needs to flick by manpower, operates cumbersome.
Summary of the invention
At the problems referred to above, the utility model will provide a kind of operation comparison labour-saving folder to turn round cutting nipper.
For achieving the above object, the technical solution adopted in the utility model is: described folder is turned round cutting nipper, mainly comprises: a pair of binding clip and a pair of pincers handle, and a pair of binding clip is movably hinged mutually by the binding clip bearing pin; The upper end of two pincers handles is movably hinged mutually by pincers handle bearing pin, and the lower body of two binding clips is movably connected on the pincers handle by a rivet respectively.
The further technical scheme of the utility model is: the lower body of two binding clips is embedded respectively in the groove on two pincers handle tops.
The another kind of further technical scheme of the utility model is: be set with on pincers handle bearing pin and strut spring.
The utility model has the advantages that: use the pliers of said structure, the power that acts on the pincers handle is delivered to binding clip by two rivets and two bearing pins, makes the active force of binding clip obviously increase, thereby reaches the labour-saving purpose when turning round in shearing or folder.

Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.
As shown in Figure 1 and Figure 2, folder described in the utility model is turned round cutting nipper and is mainly comprised: a pair of binding clip 3 and 4 and a pair of pincers handle 7 and 10, and a pair of binding clip 3 and 4 is movably hinged mutually by binding clip bearing pin 2, and their concrete connected mode is as shown in Figure 3; Two upper ends of clamping handle 7 and 10 are movably hinged mutually by pincers handle bearing pin 5, and their concrete connected mode as shown in Figure 4; Two binding clips 3 and 4 lower body are movably connected on the pincers handle 7 and 10 by a rivet respectively, its concrete connected mode as shown in Figure 5, that is: the lower body of binding clip 3 is embedded in the groove on pincers handle 7 tops, also flexibly connects mutually by rivet 6 and pincers handle 7, the lower body of binding clip 4 is embedded in the groove on pincers handle 10 tops, also flexibly connects mutually by rivet 1 and pincers handle 10, such syndeton makes more convenient to operate, activity is more flexible, and profile also better appearance is generous.
It is identical that the folder of said structure is turned round the using method that cutting nipper and the folder of traditional structure turn round cutting nipper, as long as that is: the operator holds a pair of pincers handle 7 and 10, makes binding clip 3 and 4 realize clampings, reverse or function such as shearing by being applied to power on the pincers handle 7 and 10.But, since a pair of pincers handle 7 and 10 and a pair of binding clip 3 and 4 between adopted the connected mode of two bearing pins 2 and 5 and two rivets 1 and 6, the power that acts on the pincers handle 7 and 10 is transmitted by two rivets 1 and 6, and by being similar to the effect of twice lever, make the active force that arrives on the binding clip 3 and 4 obviously increase, thereby play the labour-saving effect when turning round in shearing or folder.
In the present embodiment, as Fig. 1, shown in Figure 4, on pincers handle bearing pin 5, be set with and strut spring 8, the effect that struts spring 8 is: after the user finished once-through operation, under the effect that struts spring 8, pliers can be opened automatically, to prepare next operation, like this, more convenient to use.As Fig. 1, shown in Figure 5, in the present embodiment, on rivet 1, also be provided with a safety and buckle 9, the effect of safety button 9 is: when pliers is in state on the shelf, pliers can be closed up, and safety is detained 9 12 places, space that are buckled on the rivet 6, reach safe handling and portable purpose; In the present embodiment, as shown in Figure 5, also be provided with a wave washer 11 in the inboard of safety button 9, the effect of wave washer 11 is: it can make safety button 9 arbitrarily freely rotate, and can rotate flexibly under the effect of manpower again.
