Claims

[Scope of utility model registration request]

A vice holder 14 is attached to a base 2 that supports guide bars 3, 3 on which a square chisel machine main body 4 equipped with a drive motor 12 is guided up and down, and a vice holder 14 is mounted between the base and a vice 16 that is slidably attached to the vice holder. In a one-handed clamping mechanism for a square chisel machine that holds the main body of the square chisel machine by clamping a workpiece, a tightening screw 19 attached to the vice so as to be rotatable and prevented from moving in the axial direction is attached to the vice. It is inserted into a screw guide 23 with a substantially U-shaped cross section provided on the holder, and a half-threaded portion 25a is provided on the inner surface between the tightening screw and the vise holder so that it can be engaged with or disengaged from the tightening screw. The stopper 25 can be moved laterally, and the protrusion 25c can be inserted into the window hole 26 of the vise holder.
A strapper presser 27 is installed between the stopper and the vise so that it can be slid in the axial direction with the hand holding the handle 21, and the plate spring 34 is used to force the screw toward the tightening screw. The inclined surface 31, 32 provided on the - side is brought into contact with the mouth edge 28at30a of the vise, and a spring force is applied in one direction to attach it, and by sliding the stopper holder against the spring force, the tightening screw is tightened. A one-handed clamp mechanism for a square chisel machine, characterized in that the stopper is disengaged from the stopper.
