Vise capable of linear and rotational movement

摘要

A multiple-function clamping device includes a rotary base having an annular groove in the top thereof and scale marks are marked along in inclined surface of the rotary base. A positioning unit includes a first positioning member and a second positioning member. The positioning unit is located in the annular groove to form a linear slot. The first positioning member has a first alignment line and multiple linear marks. A vise has two side slots defined in two sides thereof so as to form an engaging portion which is engaged with the linear slot between the first and second positioning members. The vise further has a second alignment line located corresponding to the linear scale marks of the first positioning member. The vise can be moved linearly or rotatably so as to meet different requirements when machining an object.
