Description

Folding wire pliers capable of preventing objects from falling off when hands are loosened

Technical Field

The utility model belongs to the technical field of the wire cutter, in particular to folding wire cutter that loose hand can not fall the thing.

Background

Pliers are a hand tool for clamping and shearing workpieces, which is indispensable to assembly, repair, installation and other works in various industries, and have various types and wide application. The basic principle of the pliers is that two levers are crossed and connected together by a pin at a point in the middle part, so that two ends can move relatively, and an object can be pinched at the other end only by operating the tail end by hands. However, there are many problems in the use process, and the object to be clamped falls off due to improper holding or loose force during the clamping process, thereby causing damage to the object, scrapping of materials or injury to operators.

The whole operation process can be influenced by insufficient holding force, the use is very strenuous, hand muscles can be sore when the pliers are held for a long time, the labor-saving operation characteristic cannot be achieved, the hand muscles cannot be relaxed, and the pliers cannot be operated more conveniently even if the force is not uniform.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to provide the folding wire pliers which are not easy to loosen hands and can not drop objects, and the folding wire pliers have the characteristics of simple structure, labor saving in operation, economy and practicability.

In order to achieve the purpose, the invention adopts the technical scheme that: the folding wire pliers which are loose in hand and free from falling comprises two wire pliers main bodies, wherein the plier heads of the two wire pliers main bodies are rotatably connected through a second hinge shaft; the stopper moves between the slide rails for limiting, and the tail ends of the handles of the two wire pliers main bodies are connected through the sliding stopper.

The sliding limiter comprises a connecting rod, two identical articulated shafts I are arranged on the connecting rod, and one end of the connecting rod is fixed at the tail end of one of the shearing pliers handles through the articulated shafts I; the other end of the connecting rod is connected with one end of the sliding rail through another hinge shaft I; a stopper is arranged in the slide rail; a groove is arranged in the other cutting nippers handle; after the cutting nipper handles are folded, the sliding rail is rotated and then is placed in the groove together with the limiting stopper; the connecting rod and the sliding rail can be rotated and bent at multiple angles, when an object is clamped, the handles of the cutting nippers are held by hands to reach required positions, and the limiting stopper is used for rotating the cross rod to be changed into a vertical rod to be fixed.

And a spring is arranged between the upper ends of the cutting nipper handles below the second hinge shaft.

The limiter adopts a cylindrical cross rod rotating structure.

The lower part of the wire cutter main body is provided with two cutting pliers handles; two cutting nipper handles are respectively sleeved with a protective pipe sleeve made of plastic.

The utility model has the advantages that:

the utility model is used for holding the object or the spare part of the fixed wire cutter centre gripping of wire cutter in-process, can reach the purpose of release both hands, make after loosening the hand, the article of centre gripping can not drop yet.

The limiting stopper and the sliding rail are connected to a cutting pliers handle of the wire pliers through a connecting rod; the limiting stopper is used for limiting the position of one of the cutting nipper handles; the spring is arranged to ensure that the cutting nippers are in an open state after one-time use so as to be convenient for the next use; the protective tube made of plastic brings comfortable holding feeling to users.

The spring is arranged between the plier handles of the main body of the cutting pliers, and the spring is connected with the two sides of the main body of the cutting pliers, so that the cutting pliers can be restored to an open state after being used for one time, and the cutting pliers can be used for the next time; the utility model discloses be equipped with the position that the slip stopper is used for fixing another grab handle at a grab handle, the stopper can restrict the wire pliers open-ended size, guarantees that the pliers can not drop yet loose hand object when pressing from both sides the object.

After the wire pliers use, slide rail and stopper can be accomodate in taking notched grab handle through folding, and the wholeness of having guaranteed the wire pliers is higher, has avoided that the part looses, bulky, the awkward that the wire pliers was not deposited well, and overall structure and device are simple and practical.

The utility model can bring comfortable holding feeling to the user; due to the fact that the limiting device and the sliding rod are arranged, a simple movement limiting structure can be generated only by locking the limiting device, and the limiting device has the advantages of being simple in structure, labor-saving in operation, economical and practical.

Detailed Description

The structure and operation of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, 2, 3 and 4, the folding wire pliers which can not fall off when hands are loosened comprise two wire pliers main bodies 1, wherein the head parts of the two wire pliers main bodies 1 are rotatably connected through a second hinge shaft 9; the limiter 7 moves between the slide rails 6 for limiting, and the tail ends of the handles of the two wire pliers main bodies 1 are connected through the sliding limiter; the sliding limiter is used for fixing the opening and closing positions of the handles, and the fact that the pliers loosen hands when clamping objects is guaranteed, and the objects cannot fall off.

The sliding limiter comprises a connecting rod 5, two identical hinged shafts I4 are arranged on the connecting rod 5, and one end of the connecting rod 5 is fixed at the tail end of one of the shearing pliers handles through the hinged shafts I4; the other end of the connecting rod 5 is connected with one end of the sliding rail 6 through another hinge shaft I4; a stopper 7 is arranged in the slide rail 6; a groove 8 is arranged in the other cutting nippers handle; after the cutting nipper handles are folded, the sliding rail 6 is rotated and then is placed in the groove 8 together with the limiting stopper 7; make connecting rod and slide rail can the rotatory crooked of multi-angle, when the centre gripping object, hold the cutting nipper handle and reach the position that needs, become the montant with 7 rotatory horizontal poles of stopper and fix.

And a spring 2 is arranged between the upper ends of the cutting nipper handles below the second hinge shaft 9.

The limiter 7 adopts a cylindrical cross rod rotating structure.

The lower part of the wire cutter main body 1 is provided with two cutting pliers handles; the two cutting nipper handles are respectively sleeved with a protective pipe sleeve 3 made of plastic.

The utility model discloses a theory of operation is:

the utility model discloses be equipped with the spring between the pincers handle of wire pliers main part, spring coupling the both sides of wire pliers main part, there is one to force the open reaction force of wire pliers, can cooperate the better restriction wire pliers binding clip open-ended size of stopper, the position of fixed grab handle. After the wire pliers are used, the sliding rail and the limiting stopper can be contained in the grab handle with the groove through folding. The stopper can slide on the slide rail, blocks the draw-in groove on the slide rail through the rotation, and then reaches the effect of restriction pincers handle position, guarantees that the pliers can not drop yet loose hand object when pressing from both sides the object.
