Patent ID: 8403610

Claim:
A fastener for connecting a top article and a bottom article together, the top article and the bottom article each defining a hole, the fastener comprising: a sleeve comprising: a top end comprising at least one outer flange extending radially outward therefrom and at least one inner flange extending radially inward therefrom; and a lower end comprising at least one spring tab angled inwardly relative to a lateral surface of the sleeve, each of the at least one spring tab comprising an end defining an outer flange extending radially outward therefrom; a rod received in the sleeve, the rod comprising a base and a handle protruding from the base; wherein, to connect the top article and the bottom article together, the sleeve is inserted into the holes of the top article and the bottom article until the outer flange of the top end rests on the top plate, the rod is then pressed to move toward the lower end to drive the at least one spring tab to deflect outwardly until the outer flange of each of at least one spring tab is held in contact with the bottom plate, after the top article and the bottom article are limited between the outer flange of the top end and the outer flange of each of at least one spring tab, the handle is rotated to a position where the top surface of the handle resists against the inner flange of the top end, thereby preventing the base from moving upward by the elastic force from the spring tabs.
