Description

  The present invention relates to a pipe wrench, and more particularly to a pipe wrench that is a hand tool for driving a pipe member.

The conventional pipe wrench disclosed in Patent Document 1 pivots a pin block on a single shaft on one side of the main body and rotates a screwing member on the tube.
However, after turning it to a certain angle, it must be completely separated from the screwing member and must continue to rotate unless it is re-fitted, which wastes working time.

In another conventional pipe wrench disclosed in Patent Document 2, a sandwich block is pivotally connected to a main body.
However, the pivotal structure is not solid, the structure that shakes the contact action with the screwing member is relatively weak, and the structure when pivoting many pinched blocks is very complicated, and the route of each pinch block movement is It is unstable and causes inconvenience in use.
The present invention has been made in view of the above-described drawbacks of the conventional pipe wrench.
