The ring is restricted by the connecting block 4 and can no longer slide. The right end circular block 5 is squeezed by the side inclined surface of the T-block 10 and slides into the internal extrusion spring 2 11 of the connecting block 4. Then, it slides into the interior of the arc block 7 under the extrusion of the spring 2 11 to keep the arc block 7 fixed. Then, the bolt 8 can be turned so that the I-block 9 is no longer clamped with the slide groove 3. After sliding the connecting block 4 and the I-block 9 horizontally to a suitable position, the bolt 8 can be turned so that the bolt 8 and the slide groove 3 are clamped. Then, the joint plane is placed on the plane block 6, and the bending strength is measured by extrusion by the extrusion device 2. When the joint is circular, the above operation can be used to slide in the opposite direction so that the arc block 7 can support the circular joint to the middle position of the connecting block 4.
