Claims (11)

1. Insert for holding with the possibility of releasing the cutting means in the earthen rock, containing a cylindrical element, characterized in that the cylindrical element is installed inside the earth auger with the ability to move between the installation position, in which the insert holds the cutting means in the cutting position between the outer peripheral surface of the insert and the inner circumferential wall of the earth drill, and the return position, in which the insert is retracted, releasing the cutting means from the position between the outer perimeter The serial insert surface and the inner circumferential wall of the earth auger.
 2. The insert according to claim 1, characterized in that it contains a series of radially arranged and longitudinally extending keyways formed around the outer circumferential wall and at the lower end of the element for positioning and holding the cutting means in the cutting position.
 3. The insert according to claim 2, characterized in that the upper end of the insert has a profile that causes the cutting tool to rotate around the longitudinal axis of the drill when the cutting tool is installed in the earthen drill to align the cutting tool with keyways.
 4. The insert according to claim 3, characterized in that the upper end of the insert has two opposing peaks capable of contacting the tool used to transport the cutting means to and from the earth drill, and in the working position when the tool adjoins the peaks it can be rotated relative to the longitudinal axis of the drill to align the cutting tool with the keyways.
 5. The insert according to claim 4, characterized in that it comprises guide means for moving the insert in the longitudinal direction between the installation position and the return position.
 6. The insert according to claim 3, characterized in that the guide means comprises a rail or channel formed on the outer peripheral surface of the insert and capable of engaging the channel or rail, respectively formed on the inner peripheral surface of the earth drill.
 7. The insert according to claim 6, characterized in that it contains a series of longitudinally extending channels on the inner peripheral surface of the insert to form a fluid flow channel used to cool and lubricate the cutting means during the operation of the earth drill.
 8. The insert according to claim 4, characterized in that it comprises a first cam for engaging the tool while the latter moves upward at a first distance to move the insert to the return position.
 9. The insert according to claim 8, characterized in that it comprises means for disengaging the tool from the cam when pulling the tool up further than the first distance indicated.
 10. The insert according to claim 9, characterized in that the first cam is a recess made in a cylindrical element.
 11. The insert according to claim 10, characterized in that the disengaging means comprises a conical surface leading upward from the recess to the inner peripheral surface of the cylindrical element.
