[0002] A fixture is a device used to fix the object to be processed during the mechanical manufacturing process so that it occupies the correct position for construction or inspection. However, the existing round bar fixing fixture is mostly locked by the cooperation of bolts and nuts when in use. The locking method is single, and the workpiece often becomes loose during the processing due to unreliable clamp locking, thereby reducing the processing quality of the workpiece. In addition, it is often necessary to open positioning holes on the surface of the workpiece to achieve positioning and clamping of the workpiece, which in turn causes damage to the surface of the workpiece. Therefore, a device is urgently needed to replace the existing fixture to solve the existing problems. In order to solve the above problems, a round bar clamping device is first proposed.
