Claims

[Claims for Utility Model Registration] (1) A holding piece for holding down an object, an upper end protruding from a hole formed in the holding piece, and a lower end formed on a surface supporting the object. A bolt that engages with the T-groove is provided, and a spacer having approximately the same height as the bolt is interposed on the side opposite to the object to be tightened between the presser piece and the support surface of the object to be tightened, and A clamping device that fixes the object to be tightened to the object support surface by tightening a nut, the clamp device comprising:
The bolt has a connecting tool in which a toothed row is formed on at least one inner wall surface of the U-shaped groove, a toothed portion that can engage with the toothed row of the connecting tool at the lower end, and the holding piece at the upper end. an upper piece having a threaded portion that can protrude from the hole; A clamping device that is a variable length bolt consisting of a lower piece having a locking part. (2) A holding piece for holding down an object to be tightened, and a bolt whose upper end protrudes from a hole formed in the holding piece and whose lower end is formed on a surface supporting the object and engages with a T-slot. A spacer having approximately the same height as the spacer on the opposite side of the object to be fastened is interposed between the holding piece and the support surface for the object to be fastened, and a nut is fastened to the bolt. A clamping device for fixing a clamped object to the clamped object support surface,
The spacer has a toothed portion formed on at least one inner wall surface of a U-shaped groove formed at one end of the holding piece, and a toothed row that is engageable with the toothed portion formed on at least one side surface. A clamp device that is a variable length spacer consisting of a toothed rod.
