Abstract

Disclosed is a tool-free screw assembly includes a base, a stud, and a sleeve coaxially disposed on a center axis. The base has a second latching mechanism. The stud movably disposed through the base has a third latching mechanism. The sleeve movably sheathing over the stud has a first latching mechanism. In a first state, the sleeve and the base are latched by the first and the second latching mechanisms, and the sleeve and the stud are latched by the first and the third latching mechanism. In a second state, the sleeve and the base are separated from each other by unlatching the first and the second latching mechanism, and the sleeve and the stud are latched by the first and the third latching mechanism, such that the sleeve and the stud are synchronously rotatable relative to the base. A tool-free screw and an accessory thereof are also disclosed.

Dependent claims

A tool-free screw assembly comprising a base, a stud, and a sleeve coaxially disposed on a same center axis, wherein the stud is movably disposed through the base, the sleeve movably sheathes over the stud, the sleeve has a first latching mechanism and a fourth latching mechanism, the base has a second latching mechanism, and the stud has a third latching mechanism, wherein the first latching mechanism is configured to latch or unlatch the second latching mechanism, and the third latching mechanism and the fourth latching mechanism are configured to switch between different latching states, wherein

in a first state, the sleeve and the base are latched by the first latching mechanism and the second latching mechanism, and the sleeve and the stud are latched by the fourth latching mechanism and the third latching mechanism to form one of the latching states, and
in a second state, the sleeve and the base are separated from each other by unlatching the first latching mechanism and the second latching mechanism, and the sleeve and the stud are latched by the fourth latching mechanism and the third latching mechanism to form another one of the latching states, such that the sleeve and the stud are synchronously rotatable relative to the base along the center axis.

A tool-free screw configured to be locked to an object having a second latching mechanism, and the tool-free screw comprising a sleeve and a stud coaxially disposed on a same center axis, wherein the sleeve movably sheathes over the stud, the sleeve has a first latching mechanism and a fourth latching mechanism, and the stud has a third latching mechanism, wherein the first latching mechanism is configured to latch or unlatch the second latching mechanism, and the third latching mechanism and the fourth latching mechanism are configured to switch between different latching states, wherein

in a first state, the stud lock is locked to the object, the sleeve and the object are latched by the first latching mechanism and the second latching mechanism, and the sleeve and the stud are latched by the fourth latching mechanism and the third latching mechanism to form one of the latching states, and
in a second state, the sleeve and the object are separated from each other by unlatching the first latching mechanism and the second latching mechanism, and the sleeve and the stud are latched by the fourth latching mechanism and the third latching mechanism to form another one of the latching states, such that the sleeve and the stud are synchronously rotatable relative to the object along the center axis.
