The invention discloses a novel optical fiber coiling device of a laser device. The optical fiber coiling device includes a coiling motor, a supporting frame, a fixing plate, a base, an adjustable conveying plate structure, a rapid rotation seat structure, a rapid disassembly optical fiber coiling wheel structure, a connecting shaft, a coupling, a buffering rubber roller, a fixing shaft, a connecting sleeving, a baffle ring and a main switch. According to the novel optical fiber coiling device of the laser device, through the arrangement of the buffering rubber roller, the fixing shaft, the connecting sleeving and the baffle ring, the problem that the optical fiber is too hard resulting in the fact that coiling is broken in the coiling process can be prevented, and the effect of cushion protection can be achieved. Through the arrangement of a conveying connection bolt and nut and a fixing adhesive disc, safe fixation is convenient to conduct in the conveying process, and stability andreliability in the conveying process are ensured; and through the arrangement of a conveying fixing steel plate and a damping spring, the effect of cushion protection can be achieved and the problem that violent waggle appeared in the conveying or coiling process affects the work of conveying or coiling is prevented.
