Fastening apparatus
First Claim
1. A fastening apparatus, adapted to fastening a first device to a second device, comprising:
- a standoff member disposed through a through hole of said first device;
a clamp member having a clamp portion for clamping said standoff member;
a sleeve member having a hollow body and enclosing said clamp member, wherein said clamp member is compressed in said hollow body;
a resilient member wrapping around said sleeve member; and
a rotatable cam member coupled to said clamp member, wherein said rotatable cam member is rotated to a first location to compress said resilient member for causing a first preload force exerted on said second device.

Abstract
A fastening apparatus for fastening a first device to a second device is disclosed. The apparatus comprises a standoff member disposed through a through hole of the first device; a clamp member having a clamp portion for clamping the standoff member; a sleeve member having a hollow body and enclosing the clamp member, wherein the clamp member is compressed in the hollow body; a resilient member wrapping around the sleeve member; a rotatable cam member pivotly coupled to the clamp member; and a cap member arranged between the rotatable cam member and the resilient member, wherein the rotatable cam member is rotated to a first location to compress the resilient member for causing a first preload force exerted on the second device.
