摘要

the restraint system includes a blade (13) is formed of a wedge piece (15) with elongate longitudinal slot (18) extending over most of its length.the longitudinal sides (181, 182) with apertures (23) with an axis (17) and a flexible blade (16) located partly within the slot. the flexible blade has two branches (25, 26).the end (29) of the arms (26) is supported on one end (21) of the elongated piece (15).the tip (28) of the other part (25) of the lower plane of the protruding piece (15), and may be extended.when the wedge (13) is established between the blade (6) and the groove (2) in a dovetail, to lean against the bottom (14) of the groove (2).
