description The utility model belongs to a bronzing machine of a printing mechanism, and particularly relates to a leapfrog mechanism for conveying electrochemical aluminium foil. The utility model comprises a ratchet wheel, a ratchet pawl, and a ratchet pawl base in the bronzing machine. The utility model is characterized in that an electromagnet connected with a relay switch in series is controlled by a square wave generator with adjustable duty ratio to be switched on or off through an amplifier and a relay, and thus, the movement of the ratchet pawl is controlled by high-low level of the square wave. The troublesome labor that the ratchet wheel or a driving gear is in need of replacing when the leapfrog is changed originally is avoided because the duty ratio of the square wave can be adjusted conveniently.
