Description

Technical Field

[0001] This utility model relates to the field of hardware tool pliers technology, and in particular to a hardware processing tool pliers. Background Technology

[0002] Hardware tool pliers are tools used to clamp hardware parts. They can be divided into bench vises, chair vises, wire cutters, needle-nose pliers, and pliers, etc. Among them, bench vises are usually used to fix workpieces so that processing operations can be performed, such as drilling, filing, sawing, etc.

[0003] Most existing bench vises lack an angle adjustment mechanism. When machining the sides and bottom of metal materials, the jaws need to be opened and the material needs to be flipped over to be clamped again, which is very inconvenient and greatly reduces work efficiency.

[0004] Therefore, those skilled in the art have provided a tool pliers for metal processing to solve the problems mentioned in the background art. Utility Model Content

[0014] The above technical solution provides a sliding groove at the top center of the clamp, and the bottom end of the movable clamp slides inside the sliding groove, which facilitates the angle restriction of the clamp.

[0015] Furthermore, the fixed threaded rod is slidably disposed inside the limiting groove, and the width of both limiting grooves is greater than the diameter of the fixed threaded rod;

[0016] With the above technical solution, the fixed threaded rod is slidably set inside the limiting groove, which facilitates the limiting of the clamp. The width of both limiting grooves is greater than the diameter of the fixed threaded rod, thereby avoiding wear of the threads of the fixed threaded rod by the limiting groove.

[0017] Furthermore, a rotating rod is installed at the connection point between one end of the clamp and the two rotating seats;

[0018] With the above technical solution, a rotating rod is installed at the connection between one end of the clamp and the two rotating seats, so as to facilitate the rotational connection between the clamp and the rotating seats.
