A connection structure of a lamp tube comprises a multi-sectional lamp tube having a front lamp tube and a rear lamp tube, a locking rod engaged in the interior of the multi-sectional lamp tube, and a buffer structure engaged to a distal end of the locking rod. The locking rod is a polygonal embedding section and a distal end thereof has a threaded section. The threaded section of the locking rod is inserted into a resisting block of the front lamp tube and then is exactly locked to the locking seat of the rear lamp tube. The middle section of the locking rod has an embedding section. The embedding section has a resisting block. A buffer structure between the locking rod and the resisting block serves to form a tightening buffer section. Thereby, the front lamp tube and rear lamp tube can be adjusted to an aligned position.
