Grinding Block Suitable for Different Radians

Abstract

A grinding block suitable for different radians, which relates to a grinding block technique, and comprises a grinding block body, at least one soft shaft set in the grinding block body, connecting grooves set on both sides of the grinding block body and a grinding block set at the bottom of the grinding block body. The soft shaft comprises a soft shaft body and a stable shaft fit at both ends of the stable shaft. A positioner is set at a stable shaft end away from the soft shaft body and several Positioning Ribs I1 are spaced in the soft shaft body. By setting the shaft in the grinding block body and supporting the block body, the stability of the grinding block body after bending and deformation can be ensured.
