The invention discloses an interlocking mechanical locking antitheft lock. A back lock cylinder is totally separated from a front lock cylinder and a connecting body; a slide rod is arranged in a slide hole in the front lock cylinder; the connecting body is mounted in an invisible hole; an extrusion block is fixed on the slide rod; a connecting tongue at the back end of the back lock cylinder is connected with a linkage mechanism after penetrating through a via hole, and is connected with a spring bolt; a locking head is arranged in front of a locking spring in a locking bearing hole; the locking head and an ejection column are mounted in a locking hole; the slide rod in front of the ejection column is mounted in an extrusion groove and the slide hole; and an expansion end of an expansion piece extends into the extrusion groove to lock the front lock cylinder, and is connected with a locking device to lock the front lock cylinder. The interlocking mechanical locking antitheft lock integrates the mechanical interlocking, the invisibility and the connecting invisibility of the front and back lock cylinders as a whole, so that a thief cannot open an interlocking device and rotate the back lock cylinder; and even if the thief uses a barbaric method for damaging the interlocking and self-locking parts, the front lock cylinder only rotates, and the back lock cylinder dost not rotate to achieve the thorough antitheft effect.
