Jaws: The upper and lower parts of the precision vise that clamp the workpiece, also known as jaws, are flat on one side and oblique on the other.

1. The use of precision vise
precision vise, also known as flat-nose wrenches or flat-nose wrenches, are very commonly used tools in mechanical maintenance. They can be used to clamp and twist various nuts, bolts, screws and other small pieces, especially suitable for maintenance operations in small spaces.

2. The structure of precision vise
precision vise are divided into two upper and lower jaws. The jaws are adjustable to adapt to workpieces of different sizes. A screw is connected between the jaws and the handle to adjust the degree of tension of the jaws.The handle of the precision vise and the nozzle of the pliers are connected by a bracket and a hinge.

3. The names of each part of the precision vise
1. Handle: The part used to hold the precision vise is divided into two forms: straight shank and crank.

2. Jaws: The upper and lower parts of the precision vise that clamp the workpiece, also known as jaws, are flat on one side and oblique on the other.

3. Screw: The part that connects the upper and lower jaws of the precision vise, which can adjust the degree of opening and closing of the jaws.

4. Hinge: Connect the parts between the handle of the precision vise and the nozzle of the pliers to make the opening and closing of the precision vise smoother.

4. Maintenance recommendations for precision vise
1. For frequently used precision vise, they should be kept dry and should not be placed in a humid place for a long time to prevent rust.

2. It should be thoroughly cleaned after use to prevent work residues from leaving traces of oxidation on the jaws.

3. Regularly lubricate all parts of the precision vise, and you can choose some lubricants for metals to make the operation of the precision vise smoother.
