In order to solve the problem of complex structure of a traditional safety belt winder, the invention provides a safety belt winder and a safety belt device thereof. The safety belt winder comprises a winding shaft, a frame, a ratchet wheel, a locking device and a switching device, wherein the switching device comprises a transmission wheel and an automatic locking rod; as the transmission wheel is eccentrically connected with a pin column, when the winding shaft rotates, the winding shaft can drive the transmission wheel to eccentrically rotate; a first switching pin and a second switching pin are arranged on the transmission wheel; the automatic locking rod comprises a locking jaw, an induction groove and an induction jaw; the locking jaw fits an end surface tooth; and the engagement or the separation of the locking jaw and the end surface tooth is realized through the fit between the first switching pin and the induction groove and the fit between the second switching pin and the induction jaw. The safety belt winder, disclosed by the invention, effectively realizes the switching between an ALR mode and an ELR mode, and has the advantages of simpler structure, small part number, low cost, small occupied space and lower material cost and assembly cost.
