Abstract:
A buckling device of a scanning head installed at an initial position of an optic module of a scanner, wherein a slot is formed on the casing of said 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; said swingable piece has an upper stopper for being inserted into an engaging hole of said optic module; said swingable piece is installed with a lower stopper and a sliding groove is installed on the casing; a gate, a spring, and a sliding rod are installed in said sliding groove; a hooking piece protrudes from one end of said sliding groove for hooking one end of said spring at one side of said gate; another end of said spring is connected to a hook portion at an end surface of said sliding rod passing through another end of the gate; a transverse piece and a straight piece are installed on said sliding rod; the straight piece is buckled to a resisting surface at a bottom of said optic module; as said optic module returns to the initial position, said straight piece drives said sliding rod to move without hindering said lower stopper by said transverse piece so that said lower stopper forms a buckling effect.
