Abstract
The utility model provides a blade-type anti-theft lock and a key. A multifunctional eccentric wheel is installed in a round hole in a cover plate of a lock box. One end of a key chuck hooks the eccentric wheel while the other end leans against lock blades. The lock blades are installed on a round pin. The lock blades are equipped with springs. A limit pin on an opening lock blade is clamped in a groove of the key chuck. A safety bolt is installed on the round pin. One face of the bolt aligns a gap of the lock blades while the other face of the bolt clamps a square spring bolt. The safety bolt is connected with the opening lock blade through the springs. The square spring bolt and an oblique-opening lock bolt are equipped with springs and are installed in a slide groove. A slide block is installed between the two spring bolts in the slide grove. An inserting pin is installed on a straight side of a triangle oblique opening of the square spring bolt. A spring and an inserting pin are installed in an inserting pin box.
