The fastener (1) can be inserted into eyelets beneath the saw. A telescopic rail whose pieces can not be taken apart allows linear movement. A retainer plate with a curved groove in it is secured to the underside of one part of the rail. A support beam is secured inside the plate, allowing it to be rotated about an axis perpendicular to the plane of the plate. A support plate is secured to the top part of one end of the support beam. |
