Claim:
A host with a removable device, comprising: a main body, provided with an accommodation space therein; a removable device, accommodated in the accommodation space, and having a clasp block, wherein the removable device slides between a fixing position and a withdrawing position of the main body with respect to the main body; and a fixing and withdrawing mechanism, comprising: a base, fixed on the main body; a slide rod, sliding between a returning position and a pushed position with respect to the base, and having a push block, wherein when the removable device is moved from the withdrawing position to the fixing position, the clasp block pushes the push block to force the slide rod to move from the returning position to the pushed position; a first spring, connected between the base and the slide rod, for pushing the slide rod towards the returning position under a normal state; a link rod, pivoted on the base to pivotally rotate between a releasing position and a clipping position, wherein the link rod has a protruding column and a stopper portion, when the link rod is at the clipping position and the removable device is at the fixing position, the stopper portion is clipped with the clasp block to fix the removable device on the fixing position; a second spring, connected between the base and the link rod, for pushing the link rod towards the clipping position under a normal state; an actuating rod, sliding between a rebounding position and a pulling position with respect to the base, and having a guide surface, wherein when the actuating rod is moved from the rebounding position to the pulling position, the guide surface guides the protruding column to force the link rod to move from the clipping position to the releasing position; and a third spring, connected between the base and the actuating rod, for pushing the actuating rod towards the rebounding position under a normal state.
