<p>The invention relates to an actuator rod for a concealed toilet flush tank enabling the working stroke of the actuator rod to be easily adjustable. The actuator rod for a concealed toilet flush tank enabling the working stroke of the actuator rod to be easily adjustable, and comprising a levers plate, a cover plate support, a rod, a nut and a toggle lever, is characterized in that the rod (1) has guide webs (4), wherein the profile of the webs (4) corresponds to the profile of a shaped hole (16). The profile of the webs (4) is shaped as a cross wherein the four orthogonal lamellae are made in such a way that two by two are coplanar, the two planes defining a right angle. Two lamellae are coplanar to the plane of the guide shape (9) of the stem (8) of the rod (1) and have the combined length d2, while the other two lamellae are orthogonal to the plane of the guide shape (9) of the stem (8) of the rod (1) and have the combined length dl; the stem (8) of the rod (1) has a thread (6) with an external radius R; the shaped hole (16) comprises a circular hole with a diameter R1 and two additional vertical rectangular recesses with an external radius R3, wherein the following relations apply: R1 > R, R3 > d2, d2 > d1, d1 < R.</p> |
