Abstract

The utility model discloses a multifunction nipper, composed of a steel wire nipper and a knife, wherein the handle ends of the steel wire nipper and the knife are arranged with handles respectively hinged on E point and F point, while the handles are symmetry left and right and hinged at G point, the handles can prolong the torque of the steel wire nipper handle, therefore, the utility model can cut off large and thick work-piece with less force. And the nipper handle is further arranged with a lock device composed of a nut, a screw and a locking plate, therefore, the utility model can avoid sliding when detaches hex nut, to improve working efficiency. And two inner sides of the knife head and two inner sides of the knife handle are all arranged with tooth patterns, to improve application ability. And the improved structure has compact structure, multifunction, and saved force, as one novel kind of multifunctional nipper.

Description

Multifunctional pincer

Technical field

The utility model relates to a kind of multifunctional pincer that gathers multi-function in integral whole.

Background technology

Cutting pliers, scissors, adjustable wrench etc. all are indispensable instruments in daily life and the work, for people provide great convenience, yet their defective is a function singleness, when need are finished two kinds of functions, can only finish by two kinds of instruments, very bother, therefore existing people works out some multifunctional pincers, these class pincers adopt the built-in combining structure of multiple structure or the common combination of two kinds of structures usually, built-in generally is to ensconce pincers handle inside in the multiple instrument, as China Patent No. 02272755.8 " a kind of multi-functional combination plier ", its structure is to keep knife saw on the pincers handle of cutting pliers, blade, sleeve revolves tool, scissors etc., thus reach the purpose of multi-functional use; Combined type generally is that two kinds of instruments are simply made up, as China Patent No. 01242746.2 " a kind of pincers are cut ", comprise pincers handle and binding clip composition, mainly be to be extended with scissors in the rear end of binding clip, handle relative upset reaches 180 when spending to binding clip with pincers, becoming scissor construction, though this structure has also realized a kind of multi-functional purpose, yet also only is the simple combination with two simple function structures.These combination tools expose some defectives in actual use, the disconnected very difficulty of pincers when for example the ordinary steel wire pincers run into thick slightly slightly greatly workpiece, the cutting pliers of both combinations equally also are difficult to disconnected such workpiece of pincers, use effort, simple combination still can't be satisfied the demand, and makes to apply to be restricted, for this reason, it is more to release a kind of function, and the multifunctional pincer that can improve stress performance has again become pressing for of existing market.

Summary of the invention

Goal of the invention of the present utility model be to overcome the defective of prior art and provide a kind of function more, use the labour-saving multifunctional pincer.

According to the foregoing invention purpose, embodiment of the present utility model is:

A kind of multifunctional pincer, it comprises cutting pliers and scissors, it is characterized in that the shank end of described cutting pliers and scissors is provided with in opposite directions and is hinged and connected respectively in E point and F point by handle, this handle left-right symmetry and the mutually hinged G point that is connected in.

Described left and right handle is provided with the torsion spring that is sleeved on the point articulated axle of G, and these torsion spring two ends act on the inside groove of left and right handle simultaneously.

Described cutting pliers pincers handle is provided with retaining mechanism, and this retaining mechanism comprises and be fixed on a locking plate on the pincers handle that it is the mounting hole in axle center that locking plate is provided with the cutting pliers center of rotation, is provided with the screw that is connected with another pincers handle in the hole, the screw attaching nut.

Be provided with anti-slide plate between described pincers handle and the locking plate, the pincers handle surface that contacts with anti-slide plate is provided with groove.

Described scissors head two inboards and shear shank two inboards are respectively equipped with groove.

Compared with prior art, the utility model is to have set up the hinged handle of two symmetries on the combining structure of cutting pliers and scissors, prolonged cutting pliers handle moment by this handle, so use more laborsaving, also can meet the demands even run into when needing to clamp the special occasions such as workpiece that break thick slightly slightly greatly, on the cutting pliers handle, be provided with simultaneously the retaining mechanism that constitutes by dish shape nut, screw and locking plate, can not skid during the dismounting hex nut, can increase work efficiency; Inboard and shear shank two inboards of scissors head two are provided with groove simultaneously, have increased function of use, and the structure after the improvement is ingenious, and function is more, use laborsavingly, have increased new varieties for the multifunctional pincer series products simultaneously.

The specific embodiment

Embodiment is described in detail the utility model again below with reference to accompanying drawing.

As Fig. 1～shown in Figure 5, multifunctional pincer is a kind of combining structure that is made of cutting pliers and scissors.Described cutting pliers are made up of binding clip 3, pincers handle 7, are provided with the dentalation 1 of the disconnected steel wire of pincers or steel-sheet keen edge 2 and interlock hex nut in the binding clip.11 liang of inboards of described scissors head two inboards and shear shank are respectively equipped with

groove

10,12, and scissors head groove 10 can be used as nipper plier or tweezers use, and shear shank groove 12 can be used to clip broken the shell of nut, as hickory nut etc.

The shank end of the cutting pliers of described combining structure and scissors is provided with in opposite directions, and be hinged and connected respectively in E point and F point by handle 9, the trough-shaped body that this handle is stamped to form for the 1.2mm steel plate, left-right symmetry and the mutually hinged G point that is connected in, just be equivalent to prolong the moment of cutting pliers in actual use, even the disconnected big slightly thick slightly workpiece of pincers is also very laborsaving.Also be provided with the torsion spring 8 that is sleeved on the point articulated axle 17 of G on the left and right handle, and be tightened by nut 18, torsion spring two ends act on the inside groove of left and right handle simultaneously, make two handles 9 under normal condition, strut the maximum open shape that is " eight " font, torsion spring 8 has the elastic recovery effect simultaneously, duty clamps by compression, and off working state is unclamped left and right handle is automatically reset.

Also be provided with retaining mechanism on the pincers handle 7 of cutting pliers, this retaining mechanism comprises by the locking plate 5 of two rivet rivet clasps on a pincers handle, it is the mounting hole 6 in axle center that locking plate is provided with cutting pliers center of rotation 4, and screw 14 passes mounting hole, is fixed on another pincers handle by dish shape nut 13.When nut loosened, the pincers handle can be made opening and closing movement, require to need the pincers handle be locked in a certain position, fastening nut, and the aperture of jaw is promptly locked, especially when the spinning hex nut, guarantees non-sliply, increases work efficiency.Be provided with the anti-slide plate of being made by copper sheet or aluminium flake 16 between pincers handle and the locking plate, this anti-slide plate is welded on the lower surface of locking plate, and the pincers handle surface that contacts with anti-slide plate is provided with groove 15, makes that locking is more firm.

The utility model function is more, except all functions with cutting pliers and scissors, can also use as nipper plier or tweezers, perhaps presss from both sides the shell of nuts such as hickory nut, has locking function when making cutting pliers clamping hex nut.
