Abstract: The present invention discloses an isolating device comprising an isolator designed to reciprocatively support the housing of a computer by means of an insert member inserted into the body of the isolator and having the bottom end of the insert member compressibly and extensibly supported therein. The insert member comprises a base mounted to the bottom of the computer housing and two stems extending downward from the base for insertion into two insert cavities within the body of the isolator. Square-like flanges are provided on the bottom corners of the stems such that they define a reception cavity between the flanges at the end of the stems and an upward rim on the opposing sides of each stem. The isolator comprises two insert cavities within the body of the isolator having a plug extending upward from the bottom wall of each cavity for insertion into the support cavities of the stems when the insert member is inserted into the isolator.
