The invention discloses a fast-assembly handle provided with a spring, and relates to the technical field of door and window parts. The fast-assembly handle comprises a handle, a base and a connection square rod. The assembly of the handle is finished by locking and fixing the square rod through the self-locking snap spring arranged on the handle. The fast-assembly handle is simple, convenient and fast; the assembly efficiency is improved; and the labor intensity is reduced. All assembly defects of a traditional handle are overcome; and as long as a positioning hole is formed in a door, the fast-assembly handle can be easily assembled by people of all ages and both sexes.
