      <abstract xml:lang="ru">
        <p>Раскрепление обычных типов штанг в скважинах осуществляется за счет расклинивания деталей замка. Расширенияе замка требует механических усилий, а достаточное закрепление замка в породах практически не всегда удается обеспечить.</p>

        <p>Fastening of the obligatory types of rods in the boreholes is carried out by wedging of the lock parts. Expansion of the lock requires mechanical efforts, and sufficient fixation of the lock in the rocks is not always possible.</p>
