Abstract
A screwdriver includes a handle, a ratchet socket, a rotary linkage and a cap. The handle has a channel inside to accommodate the rotary linkage with one end inserted with the ratchet socket and a screwdriver socket. The rotary linkage includes a linkage, a tube, a stop section, a spring and a pivoting rod. The linkage has one end pivoted to the stop section inserted in the spring and penetrates axially in the tube. One end of the tube protrudes a wall at the inner periphery and has a pair of gaps at the end. Another end of the linkage is pivoted to the pivoting rod and the cap. The cap is pulled to draw out the linkage with the stop section at the end of the linkage to compress the spring to hold against the wall of the tube, and the pivoting rod is bent for rotation.
