Claims (1)

[Claims for Utility Model Registration] (1) A rotary operating shaft having a rotating operating portion at one end and a male threaded portion formed in a certain range in the longitudinal direction; a fixed side middle part formed in a shape and rotatable around an axis and locked in the axial direction, and a substantially cylindrical middle part formed in a substantially cylindrical shape and slidably fitted to the shaft. a middle part on the movable side having a female threaded member holding part connected thereto on the opposite side thereof; and a holding hole in which the female threaded member holding part crosses the male threaded part and is open at one end, and the inner part is accommodated in the holding hole. The part that intersects with the male thread is formed into an elongated hole or notch so that it can move forward and backward along the holding hole, and the 1/4 to 1/2 circumference engages with the male thread at the deep side of the elongated hole or notch. a female threaded member forming a female threaded portion and having one end protruding from the opening by being pressed by a spring provided on the inner side thereof;
It is formed in a block shape and has a tightening abutment surface, and has a hole through which the middle part of the fixed side passes, and is axially coupled to the middle part by a second axis perpendicular to the axis within the hole, and rotates around the second axis. The movable side has an outer portion on the fixed side in which a hole is enlarged so as to be swingable, and a tightening contact surface formed in a block shape and facing the tightening abutment surface on the outer portion on the fixed side. A moving side having a through hole through which the middle part passes, and within the through hole, the through hole is enlarged to be axially connected to the middle part by a third axis perpendicular to the axis and swingable around the third axis. A vice characterized in that it consists of an external part. (2) In the vise according to claim (1), one of the tightening abutment surfaces of each of the fixed-side external portion and the movable-side external portion is a convex abutment consisting of two surfaces perpendicular to each other. 1. A vise characterized by having a concave abutting surface formed on one surface and the other at right angles to each other.
