Patent ID: 8496217

Claim:
A pressure-applying telescopic spacer comprising: an outer tube; an inner tube telescopically coupled to the outer tube; a sleeve securely fixed to the outer tube, the sleeve having a head having an interior expansion chamber, and a hollow elongated body; a block formed by a plurality of metal rings in direct contact with each other, the block is placed inside the interior expansion chamber, the block having a top end and a bottom end, the inner tube passes through the block; a first spring placed inside the interior expansion chamber between the top end of the block and a top end of the interior expansion chamber; an anchoring spring placed between the outer tube and the hollow elongated body, the anchoring spring anchors the hollow elongated body to the outer tube; a first end support plate pivotally connected to a free end of the inner tube; a second end support plate pivotally connected to a free end of the outer tube; wherein when a force is applied to the first spring, the metal rings move from a horizontal position to an inclined position blocking an axial movement of the inner tube; and wherein the expansion chamber projects away from the sleeve forming an external handle, rotating the external handle adjusts a length of the pressure-applying telescopic spacer by acting on the first spring to increase or decrease the pressure on surfaces of support.
