Abstract
An universally adjustable precision lever structure is provided. The universally adjustable precision lever structure includes: a double spherical head lever arm, an elastic member, a linear adjusting assembly and an universal connecting assembly. In a particular use process, the double spherical head lever arm uses a center of an annular spherical surface of the universal connecting assembly as a fulcrum to realize universal rotation under an action of the linear adjusting assembly.
