[0044] Working principle: by aligning the connecting column 601 with the insertion groove 603 provided on the top of the cutting tool 5, the horizontal displacement of the cutting tool 5 is limited, the relative position of the two is accurately and stably guaranteed, then the threaded stud 604 is screwed into the cutting tool 5 and the outer wall thereof is screwed with the docking hole 602 in the middle of the connecting column 601, so as to reinforce and lock, rotate the eccentric wheel 608, make the eccentric wheel 608 rotate around the rotating shaft 607, and press the threaded stud 604 at one end of the eccentric wheel 608, thereby preventing the threaded stud 604 from loosening during use of the tool.

[0045] Then, the gas pump 2 is operated to drive the telescopic column 3 to extend and retract, the telescopic column 3 drives the mounting disc 4 fixedly connected at the bottom to move up and down, during cutting operation, the telescopic column 3 drives the mounting disc 4 and the cutting tool 5 connected at the bottom to move downward, the cutter 701 at the bottom of the cutting tool 5 cuts into the waterproof material at a precise installation angle and a sharp edge, and a standard sample is cut out.
