The rotation slot (31) is provided at an inner portion of one end of the rotating block (3) away from the first rotating shaft (11). The second rotating shaft (52) is rotatably mounted inside the rotation slot (31). Position-limiting rings (32) are embedded at an inner wall of an upper end and an inner wall of a lower end of the rotation slot (31). Two ends of the second rotating shaft (52) are inserted into the position-limiting rings (32). Symmetrically distributed springs (6) are sleeved on the surface of the second rotating shaft (52). A connecting rod (51) passing through the rotation slot (31) is provided at one end of the second rotating shaft (52). The protective sleeve (5) is provided at one end of the connecting rod (51) away from the second rotating shaft (52). A blade (4) is embedded at a side surface of the protective sleeve (5).
