<p>The present invention relates to a driver tool using a restoring force of a clockwork spring comprising: a main body (200) having a handle (100) arranged on at least one surface; a rotary shaft (400) installed through a center part of the main body (200) to be rotated, fixated on the center part of the handle (100), and having a driver blade (300) arranged on at least one end; a clockwork spring (500) wound on the rotary shaft (400); a ratchet wheel (600) installed in the rotary shaft (400); a latch (800) having one end coupled to the spring (700) fixated on one inner surface of the main body (200) and the other end installed to be hung on a sawteeth of the ratchet wheel (600); and a moving member (900) fixated on the latch (800) to move the latch (800) in an axial direction (X) of the rotary shaft (400). The present invention can fasten or release a screw using the restoring force of the clockwork spring (500); thereby making a user work easily.</p> |
