A cord reel locking mechanism for a pet lead, comprising: a brake member (2) which engages with a cord reel (1) and stops the same from rotating； an elastic member (3) which is elastically pressed against the brake member (2) to cause the brake member (2) to separate from the cord reel (1)； a pressing member (4) that contacts the brake member (2) and pushes the brake member (2) to rotate； a push button (5) slidably disposed on the pressing member (4)； and a locking block (61) that presses against the push button (5) to lock the cord reel (1). The brake member (2) and the elastic member (3) are hinged to a side wall of a lead housing (6) via a first cylindrical pin (7). A front end of the pressing member (4) is hinged to the side wall of the lead housing (6) via a second cylindrical pin (8). The locking block (61) is fixed to the side wall of the lead housing (6). An upper portion of the push button (5) protrudes outward and is provided with a toggle block (51). A lower portion of the push button (5) is provided with a locking hook (52) engageable with the locking block (61). The cord reel locking mechanism has structural simplicity, and integrates the pressing member (4), which controls a temporary stopping operation, and the push button (5), which controls an open or lock state, thereby providing operational convenience and smoothness.La présente invention concerne un mécanisme de verrouillage de bobine de cordon pour une laisse d'animal de compagnie, comprenant : un élément de frein (2) qui vient en prise avec une bobine de cordon (1) et empêche celle-ci de tourner ； un élément élastique (3) qui est pressé élastiquement contre l'élément de frein (2) pour amener l'élément de frein (2) à se séparer de la bobine de cordon (1) ； un élément de pression (4) qui entre en contact avec l'élément de frein (2) et pousse l'élément de frein (2) en rotation ； un bouton-poussoir (5) placé coulissant sur l'élément de pression (4) ； et un bloc de verrouillage (61) qui s'appuie con
