The integrated elastic pressure-regulating steel plate according to claim 1, characterized in that: The fixing screw holes provided on the steel plate body are configured as unthreaded nail holes or threaded locking nail holes, or as long nail holes which are a combination of unthreaded nail holes and threaded locking nail holes.

9. The integrated elastic pressure-regulating steel plate according to claim 8, characterized in that: The steel plate body is set as a straight steel plate or as an arc-shaped steel plate with a certain curvature consistent with the bone morphology, and the upper surface and lower surface of the steel plate body are radially set as arc surfaces with a certain curvature; the steel plate body is provided with at least one Kirschner wire hole for temporarily fixing the bone; the lower surfaces of the steel plate body and both sides of the anti-slip plate can be provided with grooves.
