工具外形如图(立体图)1所示,由偏心头内六螺钉①,六角形夹紧件②,T形挡块③和内六角螺钉④构成。T形挡块的一端加工成螺孔,并与偏心头内六角螺钉旋配;在另一端加工成沉头螺孔,并旋入内六角螺钉,以便使工具定程后紧固T形挡块。六角形夹紧件内孔套在偏心头螺钉的头部外圆上,呈间隙配
The outline of the tool is shown in the following figure (perspective view) 1, which consists of the inner hexagon screw ①, the hexagon clamp ②, the T-shaped stopper ③ and the hexagon socket head cap screw ④. One end of the T-shaped stopper is machined into a screw hole and is screwed with an eccentric head hexagon screw; at the other end, a counterbored screw hole is screwed into the hexagon head screw so as to fasten the T-shaped stopper after the tool is fixed. Hexagonal clamping pieces of the hole set in the outer head of the eccentric screw on the head, showing a gap with
