Description
Technical field
The present invention relates to a kind of pipe wrench, belong to hardware ＆ tools technical field.
Background technology
Pipe wrench is a kind of hardware ＆ tools generally used very much, existing pipe wrench although description and principle phase not to the utmost
Together, but more or less there is the defect for using that cumbersome, service efficiency is not high, the scope of application is not broad.
The content of the invention
It is an object of the invention to：A kind of new pipe wrench is provided, this kind of pipe wrench, which has, uses easy to adjust, service efficiency
It is higher and have the advantages that the scope of application is broader.
A kind of pipe wrench of the present invention, it be by：Two identical adjustable cramp pawls（1）, screw mandrel（2）, nut（3）、
Spring（4）, bearing pin（5）Handle（6）, cam（7）, jaw（8）Constituted, described handle（6）One end there is open slot
（12）, leading screw（2）One end carve conjunction in handle（6）Open slot（12）It is interior and with bearing pin（5）It is rotatably hinged at together,
Close to bearing pin（5）Lower section has and handle（6）The cam of Liancheng one（7）, in described leading screw（2）On be provided with two work
Dynamic grip finger（1）, in two adjustable cramp pawls（1）Between leading screw（2）On be provided with spring（4）, wherein one activity folder
Chela（1）The leading screw in outside（2）Upper, setting one and leading screw（2）The nut that upper screw thread is engaged（3）, further：It is described
Adjustable cramp pawl（1）It is upper that there is cross sectional shape to be elongated hole（11）, described leading screw（2）Cross sectional shape and elongated hole
（11）Shape is similar, described ridge（9）It is produced on leading screw（2）Section for circular arc portion surface on, further：
In two described adjustable cramp pawls（1）The relative position of internal orifice, one detachable jaw of installation（8）, described jaw（8）On
With teeth（10）.
Beneficial effect：The operation principle of the present invention is, when the pipeline or nut for needing to pull dimension, adjusting nut
（3）In leading screw（2）On position, make two adjustable cramp pawls（1）Opening slightly larger than the stubborn workpiece configurations size of institute, rotate handle
（6）, now cam（7）The adjustable cramp pawl mutually leaned on therewith will be compressed（1）, and bigger, the two adjustable cramp pawls that exert a force（1）
Between clamping force it is also bigger, the present invention, which has, it can be seen from the operation principle of the present invention uses easy to adjust, service efficiency
It is higher and have the advantages that the scope of application is broader.
