[0045] The working principle of the present invention is:

[0046] When in use, first hold the handle part 1, and extend the peeling part 3 into the cavity in the oral cavity. At this time, first peel off a part of the mucosa through the peeling head 22, so that the bone and mucosa in the cavity are separated by a part, and the instrument can enter the cavity by a part. Then, push the movable column 6 to slide in the movable cavity 5 through the pushing block 12. The movable column 6 drives the elastic soft rod 7 to move in the guide groove 4. The elastic soft rod 7 drives the first folding arm 9 to move upward through the connecting block 8. The first folding arm 9 and the second folding arm 10 are folded with each other, so that the hinge part of the first folding arm 9 and the second folding arm 10 extends out of the through groove 11, forming a longer peeling. At this time, under the action of the first spring 20, the inserting rod 15 is inserted into the jack 16 to limit the movable column 6, so as to further expand the peeling range of the mucosa. When it is necessary to take out the tool, press the pressing piece 18. Part of the pressing piece 18 is inserted into the contraction groove 19. The pressing piece 18 drives the inserting rod 15 to disengage from the jack 16 through the connecting piece 17. Thus, under the action of the second spring 21, the movable column 6 resets, and the first folding arm 9 and the second folding arm 10 are straightened. When the movable column 6 resets to the limit position, the first folding arm 9 and the second folding arm 10 are still in a state of slightly protruding towards the position of the through groove 11.
