A buckling device of a scanning head is installed at an initial position of an optic module of the scanner. A slot is formed on the casing of a scanner for being positioned and inserted by a swingable piece. Two lateral surfaces of the swingable piece are pivotally installed to a pair of shaft grooves on the casing by respective projecting shafts. The swingable piece has an upper stopper for being inserted into an engaging hole of the optic module. The swingable piece is installed with a lower stopper and a sliding groove is installed on the casing. A gate is installed in the sliding groove. A hooking piece protrudes from one end of the sliding groove for hooking one end of the spring at one side of the gate; another end of the spring is connected to a hook portion at an end surface of the sliding rod passing through another end of the gate. A transverse piece and a straight piece are installed on the sliding rod. The straight piece is buckled to a resisting surface at a bottom of the optic module. As the optic module returns to the initial position, the straight piece drives the sliding rod to move towards another side without hindering the lower stopper by the transverse piece so that the lower stopper forms a buckling effect.
