Abstract: The present invention relates to a security mechanism of a base, which is substantially a base. One side surface of the base is provided with a plurality of connecting ports for peripheral devices. The base is provided thereon with a trough and a retaining strip. The trough is provided therein with a connecting port. The retaining strip is disposed above one side of the trough so as to form a guard, thereby increasing the safety of the base and the performance of the computer host.

Abstract: A tiltable LCD holder comprises a base, a fixing device and at least one support device. The base has a platform on an upper end thereof. The fixing device has holes for being fixed on the platform of the base. The fixing device has two upward bended ends having a respective screw hole for screwing a respective screw bolt thereinto. The support device is connected to an object by one end thereof. The support device has screw holes on the other end for being movably coupled with the screw holes formed on the upward bended ends of the fixing device, whereby the object can be tiltable over a wide angle range to provide a steadily positioned visual angle.
