The invention discloses a lifting chain guiding device of a loop chain hand-drive block. The lifting chain guiding device comprises a pair of guide chain plates which are fixedly attached and are of a symmetric structure. A rotation center hole for containing a lifting chain wheel is formed in the middle of each guide chain plate. Chain guiding grooves are formed in the attached faces of the guide chain plates. Each chain guiding groove comprises a chain inlet segment, a chain middle segment and a chain outlet segment which are connected in sequence, wherein the chain middle segment is arranged along the semicircular edge of the corresponding rotation center hole, the chain inlet segment and the chain outlet segment are arranged on the two sides of the other semicircular edge of the corresponding rotation center hole respectively, and an isolation boss is formed in the middle segment. According to the lifting chain guiding device, the lifting chain can be well guided, and meanwhile a lifting chain and a lifting chain wheel are wrapped, so that the dustproof effect is good.
