1. A universal stepless wrench, comprising:
- a tool handle having a rotatable receiving-portion;
a first rotatable encased in the rotatable receiving-portion of the tool handle, the first rotatable allowing the tool handle to rotate freely around an inserted slideable shaft in one direction, but to engage with and lock against the inserted slideable shaft when turned in an opposite direction;
a slideable shaft for inserting into the first rotatable, whereby when the slideable shaft is inserted, the first rotatable allows the tool handle to freely rotate around the slideable shaft in one direction, but to engage with and lock against the slideable shaft when turned in an opposite direction, thereby allowing for rotation of the slideable shaft in a desired direction; and
wherein the universal stepless wrench further comprises an annular elastic cap having a central opening and covering a lip portion of the first rotatable, where the slideable shaft is inserted through the annular elastic cap and into the first rotatable.

Abstract
The present invention relates to a universal stepless wrench. More particularly, it relates to a wrench with a stepless rotatable for receiving and turning a slideable shaft in a desired direction. The rotatable allows a tool handle to rotate freely around the slideable shaft in one direction, but to engage with and lock against the slideable shaft when turned in an opposite direction. When the tool handle is moved in a locked direction, the slideable shaft is rotated, thereby rotating a socket or other suitable object.
