A quick assembly blade for a ceiling fan includes a blade frame, a blade and a press board. The blade frame has at least three studs respectively secured thereon with a fastener to be fitted in the insert holes of the blade and the engage holes of the press board. The engage holes of the press board have their rear ends respectively expanded to form a receiving hole with a comparatively large diameter. The blade is bored with a positioning hole among its insert holes, and the press board is disposed with at least one stopper at a location corresponding to the positioning hole of the blade. Thus, when the press board is assembled on the blade, the engage holes is respectively fixed with the underside of the fasteners, and the stopper is stuck in the positioning hole to prevent the press board from disengaging.

I claim: 1. A quick assembly blade for a ceiling fan comprising: A blade frame having its rear end extended and formed with a framework, said framework having its rear side provided with a pan-shaped body, said pan-shaped body fixed thereon with three studs extending upward and spaced apart, each said stud secured thereon with a fastener, said fastener having its upper end formed with a head; a blade having its front end formed with a combining portion to be assembled on said pan-shaped body of said blade frame, said combining portion of said blade bored with three insert holes to be respectively fitted on said three studs of said blade frame, said head of said fastener inserted through said insert hole of said blade and positioned over said insert hole, said blade further bored with a positioning hole at a location among said three insert holes of said combining portion; and a press board fixed on said combining portion of said blade, said press board bored with three engage holes at locations corresponding to said three insert holes of said blade, each said engage hole of said press board engaged and fixed with an underside of said head of said fastener, each said engage hole having its rear end expanded and formed with a receiving hole with a comparatively large diameter, said press board provided with an elastic stopper protruding downward at a location corresponding to said positioning hole of said blade, said elastic stopper having its front edge formed with a stop member to be stuck on an inner wall of said positioning hole of said blade. 2. The quick assembly blade for a ceiling fan as claimed in claim 1, wherein said elastic stopper is positioned at a central portion of said press board, having its rear end provided with a connecting edge connected with said press board and its front end formed with a free edge separated from said press board, said elastic stopper extending downward obliquely from said connecting edge and then bent upward to connect with said free edge, said elastic stopper extending to the underside of said press board, said free edge of said elastic stopper having its front end formed with a stop member. 3. The quick assembly blade for a ceiling fan as claimed in claim 1, wherein said press board is triangular, having its three edges respectively secured with an elastic press member positioned staggering with said three engage holes, each said elastic press member formed with a connecting edge connected with said press board and a free edge separated from said press board, each said elastic press member extending downward obliquely from said connecting edge and then bent upward to connect with said free edge, each said elastic press member extending to an underside of said press board, said elastic press member producing reverse elastic force to press against said blade for reinforcing combined stability of said press board with said blade and said blade frame. 4. The quick assembly blade for a ceiling fan as claimed in claim 1, wherein said three studs are integrally formed on said pan-shaped body of said blade frame, arranged into a triangle in position and respectively bored with a threaded hole in a center, said three studs respectively fitted thereon with a bushing, said fastener being a bolt having its upper end formed with a head with a comparatively large diameter, said fastener having its lower end formed with threads to be screwed in said threaded hole of said stud of said blade frame. 5. The quick assembly blade for a ceiling fan as claimed in claim 4, wherein said bushing is a hollow cylinder made of plastic. 6. The quick assembly blade for a ceiling fan as claimed in claim 1, wherein said press board is formed with a push member protruding upward along an annular edge of its front end. 7. The quick assembly blade for a ceiling fan as claimed in claim 3, wherein said press board has an annular edge of its front end formed with a push member protruding upward. 8. The quick assembly blade for a ceiling fan as claimed in claim 1, wherein said press board is compression made of metallic material. 9. The quick assembly blade for a ceiling fan as claimed in claim 1, wherein said press board is integrally made of plastic.
