Clamping tool for copper bar processing

Abstract

The utility model relates to copper bar technical field discloses a clamping frock for copper bar processing, including work table and copper bar main part, the upper top fixed connection of work table has the U type frame, the copper bar main part is placed below the U type frame, the inside wall of U type frame is provided with two groups of limiting mechanism that limit copper bar main part to the symmetry, in the process of processing to copper bar main part, the position of copper bar main part is adjusted accordingly, at this moment, the user can use hand to rotate the rotation of the sleeve and rotate the purpose of driving copper bar main part, and after the rotation is finished, the bidirectional movement of friction piece is used to limit the sleeve, the friction between the sleeve and friction piece increases at this moment, can reach the purpose of limiting the sleeve, and in this process, if copper bar main part needs to rotate, then needs to overcome greater friction, through this mode can avoid the copper bar main part product damage due to the rotation of the sleeve when processing the copper bar main part.
