1. A steel wire and transmission shaft connecting structure, comprising a base, wherein a plurality of transmission shafts penetrate through the base; a clamping block is arranged at one end of each of the transmission shafts; each of the transmission shafts is detachably clamped and fixed to a quick-connect shaft through the clamping block and a groove which is T-shaped and provided in one end of the quick-connect shaft; an other end of the quick-connect shaft penetrates through a butting seat and is then detachably fixed to a steel wire extending from a pipeline member; a shifting clamp is arranged between the butting seat and the pipeline member; the shifting clamp is provided with a through hole configured for the quick-connect shaft to penetrate through; the through hole is composed of a first hole portion and a second hole portion; the quick-connect shaft moves between the first hole portion and the second hole portion, which can switch locked and unlocked states of the quick-connect shaft and the shifting clamp; the base is provided with a bump; the butting seat is provided with a fixed plate; a fixing hole is provided in the fixed plate; a buckle is further arranged on the butting seat; the bump can be inserted into the fixing hole at a same time when the clamping block is inserted into the groove; and the buckle is clamped and fixed to the base,
wherein a limiting slot is provided in a shaft surface of the quick-connect shaft to form a limiting portion that is inserted into the through hole; the first hole portion is configured such that a hole surface thereof fits an outer lateral surface of the limiting portion; a slot surface of the limiting slot contacts with the shifting clamp such that the first hole portion limits a movement of the quick-connect shaft; and the second hole portion is configured to have a size larger than a cross-section size of the quick-connect shaft such that the movement of the quick-connect shaft is not limited by the second hole portion.
