Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1 to 5, a pair of pliers comprises a first pliers body 100 and a second pliers body 200, wherein the first pliers body 100 is hinged to the second pliers body 200, the first pliers body 100 comprises a first jaw section 110, a first handle section 120, and a first connecting portion 130 located between the first jaw section 110 and the first handle section 120; the second jaw body 200 includes a second jaw section 210, a second handle section 220, and a second connection 230 between the second jaw section 210 and the second handle section 220; the end of the first jaw section 110 and the end of the second jaw section 210 are respectively provided with a first clamping block 300 and a second clamping block 400; at least two screws 500 are adopted to fasten and connect the first clamping block 300 and the first jaw section 110 and the second clamping block 400 and the second jaw section 210; the width of the first clamping block 300 is greater than the width of the first jaw section 110; the width of the second clamping block 400 is greater than the width of the second jaw section 210; a first cut 131 is arranged on the first connecting part 130, a second cut 231 matched with the first cut 131 is arranged at the corresponding position on the second connecting part 230, and cutting edges are arranged on the edges of the first cut 131 and the second cut 231; a female finger cuff 600 is provided on the second handle section 220.

The first jaw section 110 is provided with a first mounting groove 111 matched with the first clamping block 300; be equipped with on the second jaw section 210 with second grip block 400 matched with second mounting groove 211, wherein, the thickness of first grip block 300 is greater than the groove height of first mounting groove 111, the thickness of second grip block 400 is greater than the groove height of second mounting groove 211, make the lower surface of first grip block 300 not be located the coplanar with the lower surface of first jaw section 110 like this, the upper surface of second grip block 400 is not located the coplanar with the upper surface of second jaw section 210, thereby make the pliers when utilizing first grip block 300 and second grip block 400 to carry out the centre gripping to the object tight dynamics of clamp bigger, more be difficult for appearing relative slip.

Screw through holes 510 matched with the screws 500 are formed in the first clamping block 300 and the second clamping block 400; the depth of the screw passing hole 510 is greater than the thickness of the nut of the screw 500, thereby preventing the nut portion of the screw 500 from affecting the clamping effect of the pliers.

The first clamping block 300 and the second clamping block 400 are equal in width; four corners of the lower surface of the first clamping block 300 protrude outwards to form a first protrusion 310; the center of the lower surface of the first clamping block 300 protrudes outwards to form a second protrusion 320; the front and rear corners of the upper surface of the second clamping block 400 protrude outwards to form a third protrusion 410, the length of the third protrusion 410 is equal to the distance between the first protrusion 310 and the second protrusion 320, and the friction between the first clamping block 300 and the second clamping block 400 and the object is increased, so that the object can be clamped more tightly.

In the present embodiment, the length of the first clamping block 300 is designed to be longer than the length of the second clamping block 400, which is mainly to avoid the situation that the first clamping block 300 and the second clamping block 400 are reversely mounted.

The width of the first protrusion 310 is one fifth of the width of the first clamping block 300; the length of the first protrusion 310 is one fifth of the length of the first clamping block 300; the width of the second protrusion 320 is one fourth of the width of the first clamping block 300; the length of the second protrusion 320 is one fourth of the length of the first clamping block 300; the width of the third protrusion 410 is two thirteen-thirds of the width of the second clamping block 400.

The second handle section 220 includes an arcuate transition portion and a horizontal portion; the arc-shaped transition part is connected with the second connecting part 230, and when an object is clamped, the arc-shaped transition part can increase the stroke between the second handle section 220 and the first handle section 120, so that the clamping force is increased; the included angle between the first handle segment 120 and the horizontal line is 1 degree, which facilitates the opening and closing between the second handle segment 220 and the first handle segment 120.

The first connecting portion 130 is provided with a matching groove 132 matched with the second connecting portion 230 for facilitating the hinge matching.

According to the pair of pliers, the contact area between the pliers and an object is increased when the pliers are used through the arranged first clamping block 300 and the arranged second clamping block 400, the object can be clamped more tightly, looseness is prevented, meanwhile, the first clamping block 300 and the second clamping block 400 are arranged in a detachable mode, the first clamping block 300 and the second clamping block 400 are convenient to replace after being worn, the first pliers body 100 and the second pliers body 200 can be recycled, cost is saved, and waste of resources is reduced; the first cutting opening 131 and the second cutting opening 231 are matched to cut off objects such as iron wires, so that the application range of the pliers is enlarged, the pliers are multifunctional, and the female finger stall 600 arranged on the first handle section 120 facilitates holding and opening and closing of the pliers.
