[0017] 1. The utility model provides a bracket, a spring and a pressure wheel, so that the chip position of the long rod is supported by three points through the contact between the two pressure wheels and the blade and the long rod, thereby avoiding the swing of the long rod itself and the swing caused by the blade cutting, thereby avoiding the error of the cutting size;

[0018] 2. The utility model also provides a reinforcement rod so that the first mounting column and the second mounting column will not fall over or move away due to the reaction force. BRIEF DESCRIPTION OF THE DRAWINGS
