FIELD: instrument making.
SUBSTANCE: invention relates to the used for reconnaissance or detection using electric or magnetic means instruments and devices repair. Claimed device design is shown in more detail in fig. 2, where 1, 2 are the fixedly attached to the end cover flange steps, 3 is a rectangular groove for the battery compartment cover 4 tightening/unscrewing, 5 is the probe extraction tool plate, 6 is connected to the plate the probe extraction tool rod, 7 is the probe battery compartment, 8 is the drilling head. Battery unit end cover with a flange implementation in the form of the two-stage in height cylinder with steps different diameter, the larger of which is the external and has a diameter smaller than the end cap diameter, and a rectangular transverse groove in the flange entire height, in conjunction with the device second part implementation from located outside the probe body separate element, in the form of a flat plate, commensurate with the groove in the flange dimensions, equipped with bent opposite each other brackets, by the brackets opposite side fixedly attached to the rod, passing through its central axis and having the ability of its rotation around its axis so that with the end cover and separate element connection outside the battery unit housing, a part of the plate with brackets enters into the flange groove, and the brackets at its edges go under the flange top step, providing the end cap secure gripping and removal the from the battery compartment very simple device design.
EFFECT: end cap manufacturing technology simplification while facilitating its installation and removal possibility.
