Abstract
A precision handle for hand tools has a body, an elastic element, a sheath, a pressing element, and a group of balls. The mounting protrusion protrudes axially from a rear end of the body. The elastic element is mounted in the body. The sheath is mounted around the mounting protrusion. The pressing element is mounted through and engages with the sheath. The group of balls includes a first ball and a second ball. The first ball is mounted in the mounting protrusion and abuts the elastic element. The second ball is mounted between the pressing element and the first ball. The first ball abuts against the second ball at one point of contact when the pressing element is pressed, thereby decreasing the friction between the body and the sheath. Accordingly, the precision handle for hand tools can be operated smoothly and efficiently.
