Stopping mechanism for stopping or releasing a horological regulating or chronograph mechanism wheel

A stopping mechanism (100) for triggering the stopping or release of a regulating or chronograph mechanism wheel (1) of a timepiece (1000), including a structure (500) and at least a first bridge (600) on either side of said wheel (1) which is rotatable about a main axis (D), said stopping mechanism (100) including a control organ (210) which can be operated directly or indirectly by a user and linked with a stopping lever (2) which includes at least one support surface (20) arranged to bear on a complementary front and/or edge support surface (11) of said wheel (1), said stopping lever (2) being movable between a working position where any said support surface (20) is at a distance from said complementary support surface (11) and where said wheel (1) is free to rotate, and a stopping position where at least one said support surface (20) is bearing on said complementary support surface (11) and where said wheel (1) is in a rotation stopping position,

• wherein said stopping lever (2) includes, rigidly connected to each other and rotatable together with respect to a pivot axis (DP) parallel with said main axis (D), a first control part (21) which is linked in a removable manner with said control organ (210), at a link axis (DA) parallel with said pivot axis (DP), said removable link allowing a substantially planar extraction or insertion of said first part (21) with respect to said control organ (210), perpendicularly to said link axis (DA), and a second support part (22) including said at least one support surface (20) and which is movable between said structure (500) and said first bridge (600), and
• wherein said stopping mechanism (100) further includes at least one elastic return means arranged to exert an axial force on said stopping lever (2) and press it on said structure (500).

• wherein said stopping lever (2) is inserted between said structure (500) and a second bridge (700), included in said stopping mechanism (100), which define together a chamber (800) wherein said stopping lever (2) is fitted, at the pivot axis (DP), in an axially removable manner with respect to said rotation guidance element (510).
