A wire connection device is used in a ceiling lamp. The connection device comprises a retaining seat engaged to a wire box and an inserting rod inserted into an interior of the retaining seat. A plurality of via holes are formed around a periphery of the wire box. A lateral side of the retaining seat extends with an engaging portion, and a polygonal inserted hole is formed in the engaging portion. The engaging portion is inserted into the wire box. The retaining seat has a step-like receiving hole; the receiving hole being installed with a buckling unit for buckling the inserting rod. A portion of the inserting rod is a polygonal rod; a lateral side the polygonal rod has a buckling hole which is aligned to the receiving hole of the retaining seat; and the buckling hole exactly resists against the buckling unit.

1. A wire connection device of a ceiling lamp capable of being assembled by users, the wire connection device comprising a retaining seat engaged to a wire box and an inserting rod inserted into an interior of the retaining seat wherein a plurality of via holes are formed around a periphery of the wire box, a locking device is installed within the wire box by studs and nuts; a lateral side of the retaining seat extends with an engaging portion, a polygonal inserted hole is formed in the engaging portion; the engaging portion is inserted into the wire box; a positioning nut at an inner side of the wire box of the engaging portion locks the retaining seat in the interior of the wire box; the retaining seat has a larger lateral surface which has a step-like receiving hole; the receiving hole is installed with a buckling unit for buckling the inserted rod; and a portion of the inserting rod inserting into the inserted hole of the retaining seat is a polygonal rod; a lateral side of the polygonal rod has a buckling hole which is aligned to the receiving hole of the retaining seat; and the buckling hole exactly resists against the buckling unit; thereby, only a small volume is required for transferring and storing the wire connection device, and a user can assembly the device by himself or herself. 2. The wire connection device of a ceiling lamp capable of being assembled by users as claimed in claim 1, wherein the buckling unit is formed by a push rod with a larger ring at a middle section thereof, a spring engaged around the push rod, and a stopping ring which is locked to the retaining seat and for retaining the push rod and the spring to the retaining seat; an end portion of the push rod exactly protrudes to an interior of the inserted hole of the retaining seat; the larger ring resists against the step-like surface of the receiving hole for preventing the push rod from entering into the inserted hole. 3. The wire connection device of a ceiling lamp capable of being assembled by users as claimed in claim 1, each of the via holes of the wire box has buckling grooves at two sides thereof; two sides of the engaging portion are formed with two resisting blocks at positions corresponding to those of the buckling grooves of the via hole. 4. The wire connection device of a ceiling lamp capable of being assembled by users as claimed in claim 1, wherein a predetermined portion of the inserting rod has a resisting surface; after the buckling unit is inserted into the buckling hole, the resisting surface exactly resists against a distal end of the retaining seat, thereby, the inserting rod is stable without vibration. 5. The wire connection device of a ceiling lamp capable of being assembled by users as claimed in claim 1, wherein the inserted hole of the engaging portion has a shape selected from one of a group containing a round shape, a triangular shape, a rectangular shape, and a pentagonal shape. 6. A wire connection device of a ceiling lamp capable of being assembled by users, the wire connection device comprising a locking structure for fixing a body of a wire box, the wire box has a cover; a retaining seat engaged to the wire box and an inserting rod inserted into an interior of the retaining seat wherein a plurality of via holes are formed around a periphery of the wire box, a locking device is installed within the wire box by studs and nuts; and the locking structure is formed by two pieces of disk-like washers which are engaged by screwing; a screw rod passes through the disk-like washers and then nuts are used to fix the screw rod from two ends of the screw rod; studs and nuts are further used to fix the disk-like washers from a reverse direction of the screw rod so as to be connected to the body and the cover of the wire box; wherein the interior of the wire box has a large space so that electric wires can be inserted therein.
