Abstract

This utility model relates to a kind of long force moment tools pincers, comprise: have the recessed grain can depositing another flexible handle in the tong arm partial design of tool tong, groove internal memory is placed with the flexible handle of rotatable 180 °, the turning cylinder of fixing tong arm and flexible handle is had in tong arm tip designs, flexible handle can rotate hauling-out for lengthen tong arm, person's work easy to use is had an effect, compared with clamping with existing general tool, the utility model tool tong increases tong arm by lever principle, flexible handle can rotate contraction, also moment can be increased according to its needs, reach the object reducing user and exert oneself, solve the situation that common pincers cannot turn in the not enough situation of hand-power.

Description

Long force moment tools pincers

Technical field

The utility model relates to routine use hardware & tools field, is a kind of clamping, fixing processing work or torsion hand tools pincers in particular.

Background technology

Current tool tong is made up of binding clip and clamp handle, and the principle that pliers uses is that less external force (as the hand-power be applied on tong arm) is changed into larger power, makes pliers effectively to clamp or to shear.When being applied to the external force on tong arm and increasing along with leverage, the active force of jaw produces the external force of a clamping movement.If produce a larger external force, the distance from the center of pliers riveting location to handle must be long as much as possible, must short as much as possible (lever principle) from clamp port or sheared edge to the distance at riveted joint center.But in routine use, can run into the situation that many hand-powers deficiency cannot turn, this just causes difficulty to user, needs to find to the tool tong of long moment.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, this utility model tool tong can not only use as general purpose tool pincers are normal, its design feature comprises: have the recessed grain can depositing another flexible handle in the tong arm partial design of tool tong, groove internal memory is placed with the flexible handle of rotatable 180 °, the turning cylinder of fixing tong arm and flexible handle is had in tong arm tip designs, flexible handle can rotate hauling-out for lengthen tong arm, person's work easy to use is had an effect, compared with clamping with existing general tool, the utility model tool tong increases tong arm by lever principle, flexible handle can rotate contraction, also moment can be increased according to its needs, reach the object reducing user and exert oneself, solve the situation that common pincers cannot turn in the not enough situation of hand-power.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is front elevation of the present utility model.

Fig. 2 is tool tong stereogram.

Fig. 3 is tool tong work enforcement figure.

1. binding clip, 2. flexible handle, 3. tong arm, 4. turning cylinder in figure, 5. deposit the groove of handle.

Detailed description of the invention

Composition graphs 3 describes a specific embodiment of the present utility model in detail, in the utility model tool pliers structure, 2. flexible handle can be taken out from the groove 5. depositing handle, 2. flexible handle is pulled open by rotating 180 °, utilize lever principle, thus increase the length of tong arm, reach the object reducing user and exert oneself, solve the situation that many hand-powers deficiency cannot turn.

The utility model have employed just force application arm and reduces the structure had an effect, and designs ingenious, easy to implement, is the both practical and convenient technological improvement of the utility model one.

Claims

1. one kind long force moment tools pincers, include binding clip, tong arm, flexible handle, turning cylinder, deposit the groove of handle.It is characterized in that: the tong arm partial design of described tool tong has the recessed grain can depositing another flexible handle, groove internal memory is placed with the flexible handle of rotatable 180 °, have the turning cylinder of fixing tong arm and flexible handle in tong arm tip designs, flexible handle can rotate hauling-out for lengthen tong arm.
