Needle guiding device for a drilling resistance measuring device, drilling resistance measuring device and drilling resistance measuring method for the condition examination of wood

摘要

The present invention provides a needle guide device (2) for a predetermined drill resistance gauge, a drill resistance gauge for characterizing wood itself, and a wood texture inspection method. The needle guide device (2) for the drilling resistance measuring device is designed to guide the drilling needle (1) and to be operatively coupled to a drive of the drilling resistance measuring device. In this case, the needle guide device (2) on a support device and a needle holder (4). The needle holder (4) has a chuck adapted to receive the predetermined drilling needle (1), and the supporting device extends in the longitudinal direction of the predetermined drilling needle (1). According to the invention, the supporting device has at least one scissor lattice device (8) with a scissor lattice (8 ') made of struts (81), or a drive device which has two co-acting force transmission elements arranged parallel to one another.
