<p>The invention relates to instruction to an X ray intercepting mechanism. A slit mechanism device is provided with two slit plates (L3, L4) for adjusting the width of the X ray, two slit connecting rods (S2, S4) axially installed at the two ends of the two slit plates to link the two slit plates, two axes (R1, R2) respectively provided with the two slit connecting rods to ensure the two slit connecting rods to rotate, two intercepting plates (L1, L2) intercepting the X ray or allowing the X ray to pass and two intercepting levers (S1, S3) supported at the two ends of the two intercepting plates with the axes to link the two intercepting plates and installed on the two axes with the two slit connecting rods.</p> |
