Description

Multiduty pliers

Technical field

The utility model relates to a kind of hardware ﹠ tools, is specifically related to a kind of multiduty pliers that pincers worker is used that is suitable for.

Background technology

As far back as the forties in last century, the American has invented " combination pilers ", photo was once published on certain magazine, the eighties China market has a kind of " locking pliers ", utilize its principle to make, its moulding is bad, and head is very big, accounts for a lot of operating spaces, dumb, two jaws of die forging, two tong arms of compacting, rolling accent mouth bolt, precision is all very poor, riveted joint during general assembly is very coarse, and the very easily uneven pincers of two jaws are opened, and has therefore limited widely its scope of application and the result of use and the life-span of having dwindled it.

Summary of the invention

Problem to be solved in the utility model is to propose a kind of multiduty pliers at above-mentioned prior art, and its precision is good, and the moulding exquisiteness is used flexibly.

The utility model is adopted solution to be by the problem of the above-mentioned proposition of solution: multiduty pliers, include jaw one, jaw two, tong arm one, tong arm two, push rod, transfer a mouthful bolt, extension spring and drag-line, one end section of tong arm one is a U-shaped, the jaw one and the jaw two that is being hinged are being connected in the described tong arm one, the afterbody of push rod can slide in U-lag, the other end of tong arm one is for there being the Φ 16 gardens pipe of M14 * 1mm screw, pack into and transfer a mouthful bolt, the section of tong arm two is a U-shaped, the head of jaw two and push rod is being hinged in its groove, the also backing pin of restricted push rod and the fixedly little pin of one of extension spring, the other end of extension spring hangs drag-line, and the other end of drag-line is fixed in the little trough in jaw two outsides, and extension spring pulls to counter-rotating to jaw two by drag-line often opens jaw, transfer a mouthful bolt to be screwed into the top push rod, top tong arm two top jaw two again makes two jaws dwindle.

When using these pincers, earlier under two tong arm rounding states, adjust jaw to being slightly smaller than the object that needs clamping with transferring mouthful bolt, open two tong arms then, draw jaw in two tong arms of holding with a firm grip again facing to object, promptly this object is clamped, decontrol hand, this object can not come off, and clamping force is constant, and its principle is: the contact point of two hinges and push rod and accent mouth bolt 3 points on the tong arm two, by out-of-line power more a little it is faded to when in alignment, the top power of giving jaw two is that the clamping force of jaw is greatly, surpasses this straight line little by little, because the backing pin in the tong arm two blocks push rod, can not be many again, then the clamping force of jaw also just reduces a little, can not reduce, so clamping force is still very big and constant after decontroling hand again.

The beneficial effects of the utility model are:

1) decontrol the hand object after the grip objects and also can not come off, clamping force is constant all the time;

2) can be used for dismantling the object that all non-detachable various screws of any other instrument, bolt, nut, pin, nail etc. must be removed;

3) can clamp processing such as the various workpiece of 0.1～43mm bore, grind, file, saw, scrape, heat, forge;

4) workpiece that can clamp more than two bores a plurality of equidistant isometrical hole (will clamp with two multiduty pliers) or holes concentric with workpiece simultaneously on different positions;

5) can make spanner, bench vice, pipe wrench usefulness temporarily;

6) can cut off Φ 4mm zinc-coated wire, or Φ 3.2mm stainless steel steel wire;

7) can adorn, tear open the steel nail special use to patient's fracture site at hospital orthopedics;

8) can be clamped in the interim hook of work on the object.
