A base frame for holding fixtures used in woodwork includes an extruded body having a raised top central portion formed into a dovetailed open-topped upper channel, two lowered wing portions located at each lateral side of the upper channel and formed into two symmetrically identical open-topped side channels with a height difference between the tops of the upper and the side channels, and a big-size open-bottomed lower channel formed below said upper channel and said two side channels. With the height difference between the upper and the side channels, two base frames may be perpendicularly connected to each other in the same plane using a U-shaped connecting bracket flush with the top of the upper channel, or superposed with the upper channels facing toward each other by locking inserting blocks in each open-sided channel formed between two side channels at the same side of the two superposed base frames.

The invention relates to a device for affixing to cylindrical components of medical instruments, for instance an instrumental shaft, having at least one intake part that can be mounted on the cylindrical component and can be affixed to the cylindrical component, wherein a sleeve-shaped collet chuck that essentially coaxially surrounds the cylindrical component is positioned in the intake part and whose inner diameter can be displaced between a span that can slide along the cylindrical component and a span that is in form-locking contiguity on the cylindrical component. To allow for a stationary clamping on the one hand and ensure a non-harmful clamping of the cylindrical component on the other hand, it is proposed with the invention that the inner diameter of the collet chuck can be displaced by a slider that can slide essentially diagonally to the cylindrical component and is mounted so that it can slide in the housing of the intake part.
