2. The assembly of claim 1 , wherein the short arm holds the adjustable length internal lever arm at an adjustable angle.
3. The assembly of claim 2 , wherein the adjustable angle is rotatable.
4. The assembly of claim 2 , wherein the short arm comprises a connection mechanism for attachment to the adjustable length internal lever arm, and wherein the connection mechanism allows for locking and unlocking of the adjustable length internal lever arm at different angles with respect to the short arm.
5. The assembly of claim 4 , further comprising a connection mechanism on the adjustable length internal lever arm, wherein the connection mechanisms on the short arm and on the adjustable length internal lever arm interlock with one another.
6. The assembly of claim 4 , wherein
the connection mechanism on the short arm comprises outwardly deflectable teeth, and wherein,
the connection mechanism on the adjustable length internal lever arm comprises teeth positioned within the outwardly deflectable teeth of the short arm.
7. The assembly of claim 4 , wherein
the connection mechanism on the short arm comprises inwardly facing teeth, and wherein
the connection mechanism on the adjustable length internal lever arm comprises inwardly deflectable teeth within the inwardly facing teeth of the short arm.
8. The assembly of claim 4 , wherein
the connection mechanism on the short arm comprises vertically projecting gear teeth, and wherein
the connection mechanism on the adjustable length internal lever arm also comprises vertically projecting gear teeth, and wherein
the vertically projecting gear teeth on the short arm mate with the vertically projecting gear teeth on the adjustable length internal lever arm.
9. The assembly of claim 8 , further comprising:
a locking plug for holding the short arm against the adjustable length internal lever arm.
10. The assembly of claim 1 , wherein the short arm passes through a wall of a toilet tank.
