A safe guide device, comprising light-emitting lines and a multi-channel alternating current driver (9) driving the light-emitting lines to operate; more than three light-emitting lines are arranged from front to back or arranged in parallel from left to right to form an arrow shape; the light-emitting lines comprise a first light-emitting line (3), a second light-emitting line (4), a third light-emitting line (5), a fourth light-emitting line (6), a fifth light-emitting line (7) and a sixth light-emitting line (8); the first light-emitting line (3), the second light-emitting line (4) and the third light-emitting line (5) are right hand twisted, or sequentially right hand wound around a first core shaft or a first core wire to form a first sequentially segmented light-emitting cable (1); the fourth light-emitting line (6), the fifth light-emitting line (7) and the sixth light-emitting line (8) are left hand twisted, or sequentially left hand wound around a second core shaft or a second core wire to form a second sequentially segmented light-emitting cable (2); the first sequentially segmented light-emitting cable (1) and the second sequentially segmented light-emitting cable (2) are arranged in parallel from left to right; and the first light-emitting line (3) and the fourth light-emitting line (6) form an arrow shape. The safe guide device has the characteristics of simple and reasonable structure, flexible operation, clear guidance, and wide application range.
