when the blade 9 needs to be extended out for use, the sliding block 6 is pressed downwards, the sliding block 6 is pressed into the sliding groove 41, the free end of the elastic sheet 72 is bent towards the second groove 21, meanwhile, the sliding block 6 drives the clamping block 61 to move downwards until the protruding part of the clamping block 61 is separated from the clamping groove 42, and the blade 9 is unlocked. At this moment, due to the blocking of the limiting block 211, the elastic sheet 72 can only be bent in a small range, so that the clamping block 61 cannot move down too much, the clamping block 61 can just be separated from the clamping groove 42 and cannot be separated from the groove three 91, and therefore, when the bearing sheet 7 slides, the blade 9 cannot be separated from the bearing sheet 7. After the fixture block 61 is separated from the slot 42, the fixture block 6 is kept pressed and the slide block 6 slides in the chute 41, the slide block 6 drives the fixture block 61, the elastic sheet 72, the bearing sheet 7 and the blade 9 to slide together, the blade 9 extends out or retracts from the notch 22 at the tail of the upper clamp plate 2, and then the action of stretching the blade 9 can be completed, when the expected stretching position is reached, the protruding part of the fixture block 61 is clamped into the adjacent slot 42 nearby, and the cutting operation is performed after the bearing sheet 7 and the blade 9 are locked.

When the blade 9 needs to be detached and replaced, the sliding block 6 is pressed and slid to the area of the second groove 21 without the limiting block 211, the sliding block 6 and the fixture block 61 can be pressed deeper due to the fact that the limiting block 211 does not exist, until the protruding portion of the fixture block 61 is separated from the third groove 91, the blade 9 can freely slide on the bearing sheet 7 at the moment, and the blade 9 can be directly poured out of the notch 22 to complete detachment of the blade 9. When a new blade 9 is installed, the sliding block 6 and the fixture block 61 are kept pressed deeply, the blade 9 is inserted into the notch 22, the third groove 91 of the blade 9 is controlled to be above the protruding part of the fixture block 61, the sliding block 6 and the fixture block 61 are loosened, the elastic sheet 72 drives the fixture block 61 to reset, and the protruding part of the fixture block 61 is clamped into the third groove 91, so that the blade 9 can be fixed on the bearing sheet 7. And then, the slider is pressed shallowly according to the method, and the telescopic blade 9 is used. Because the blade can only be replaced in the area of the second groove 21 without the limiting block 211, the use safety of the blade is effectively ensured.
