The invention relates to a double-drawing opening type engine cover lock. The upper portion of a double-drawing connecting rod and the lower portion of a ratchet wheel are jointly installed on the front face of a lock base plate through a first pin shaft. One side of the lower end of the double-drawing connecting rod is used for being connected with a drawing wire, and the other side of the lower end of the double-drawing connecting rod is connected with the lock base plate through a first spring. The upper end of the right side edge of the double-drawing connecting rod is provided with a stop block matched with the ratchet wheel. A limiting pin is installed in the middle of the right side edge of the double-drawing connecting rod. A first ratchet groove is formed in the middle of the right side edge of the ratchet wheel, and a second ratchet groove is formed in the upper portion of the right side edge of the ratchet wheel. A pawl is arranged on the right side of the ratchet wheel and installed on the front face of the lock base plate through a second pin shaft. A lock hook, a first jaw hook, a second jaw hook and a second spring connector are sequentially arranged on the periphery of the pawl in the anticlockwise direction. A limiting plate is arranged below the right side of the double-drawing connecting rod and the pawl. The middle portion of the limiting plate is installed on the front face of the lock base plate through a third pin shaft. The upper side edge of the limiting plate is in contact with the lower end of the second jaw hook in a matched manner. The left end of the limiting plate is matched with the limiting pin. A torsional spring is arranged between the limiting plate and the lock base plate. By the adoption of the double-drawing opening type engine cover lock, a user can completely open an engine cover in a cab, and the double-drawing opening type engine cover lock is easy and convenient to use.
