4results about How to "Save complexity" patented technology

The application discloses a multifunctional cutting device and a use method, which comprises a cutting platform, a cutting machine arranged on the cutting platform, a processing groove arranged on the cutting platform, an opening end of the processing groove facing a side surface of the cutting platform, a bottom surface of the processing groove being inclined, so that when a test piece is placed in the processing groove, an end of the bottom surface of the processing groove far from the cutting platform serves as a fulcrum, and a top surface of the processing groove serves as a limiting part, and the width of the top surface of the processing groove is smaller than the width of the bottom surface of the processing groove, one end of a fixing adjusting part penetrating through the top surface of the processing groove and extending into the processing groove to abut on the test piece, so that a lever balance structure is formed between the top surface of the processing groove, the test piece, the fulcrum and the cutting machine or between the fixing adjusting part, the test piece, the fulcrum and the cutting machine in the cutting process. The multifunctional cutting device can guarantee the cutting precision of the test piece, quickly complete the cutting of the test piece, and meet the cutting requirements of test pieces with different sizes or the same test piece for multiple times.
