3. The clamping component is set so that the operator does not need to hold the threaded rod, so as to save labor. When turning the lifting rod, in order to prevent the threaded rod from rotating and affect the operation of the lifting rod, turn the clamping rod to make the block move. The side clamps clamp the threaded rod so that it cannot rotate.
