Problems solved by technology
These two structures both have self-locking functions, but their structures are complex, costly, and expensive. When the diameter of the clamped workpiece is larger, it is necessary to forcefully open the handle and press the handle to lock the object. It is difficult to achieve one-handed operation, and The large operating space makes it very difficult for the staff to operate and is inconvenient to use

Description
technical field [0001] The invention relates to the technical field of manual tool pliers, in particular to an automatically adjustable pliers. Background technique [0002] Existing traditional pliers generally are made up of fixed jaw, movable jaw, fixed handle, movable handle, support plate, lifting plate, extension spring, adjustment screw, rivet. When in use, the operator should press hard on the handle to make the jaws touch the workpiece, and then press the handle hard to lock the workpiece, that is, hold the locking mechanism to clamp the workpiece, open the locking mechanism to loosen the workpiece, during use, operate It is very laborious; since the opening of the jaws is fixed, when clamping different workpieces, when the size of the opening needs to be constantly changed, it must be adjusted manually, and the bolts are repeatedly rotated with both hands to make the jaws reach The amount of opening required to clamp and disengage the workpiece is cumbersome, time...
