The invention discloses a bead-free additional asynchronous mechanical antitheft lock. A rear lock cylinder and a front lock cylinder of the bead-free additional asynchronous mechanical antitheft lock are completely disconnected; a slide hole, a special key hole and a stealth hole are formed in the front lock cylinder, a connecting body is installed in the stealth hole, and the connecting body and the rear lock cylinder are disconnected; a locking hole and a connecting hole are formed in the rear lock cylinder, a connecting tongue on the rear end of the rear lock cylinder penetrates through a through hole to be connected with a link mechanism and further to be connected with a lock tongue; a locking head is arranged in front of a locking spring in a locking bearing hole, the locking head and an ejector column are installed in the locking hole, and a slide rod in front of the ejector column is installed in an expansion groove and the slide hole; the expansion end of an expansion sheet props against the interior of a locking groove to lock the front lock cylinder, and the front lock cylinder is locked in a rotating manner. According to the bead-free additional asynchronous mechanical antitheft lock, mechanical interlocking, stealth and connection stealth of the front and the rear lock cylinders are integrated, so that a thief cannot open an interlocking device and cannot rotate the rear lock cylinder; even if the interlocking and self-locking part is damaged by utilizing a brutal means, only the front lock cylinder can be rotated, the rear lock cylinder cannot be rotated, and a complete and thorough antitheft effect can be realized.
