[0024] The cross-sectional shape of the rotating block 3 is an odd-numbered regular polygon. A hydraulic sleeve 12 is fixedly installed on the inner top wall of the fixed frame 2. A fixed sleeve 13 sleeved on the edge of the rotating block 3 is fixedly installed on the free end of the hydraulic sleeve 12. This arrangement can ensure that the working surface corresponds exactly to the edge, and the device is subjected to uniform force by arranging the inside of the fixed sleeve 13.
