Abstract: A ratchet wrench includes a parts replacement structure that ensures effort-saved and smooth operation and prevents parts from getting lost. The wrench has a handle having an end forming a head portion that rotatably receives therein a driving collar. A lid plate is fixed to the head portion to retain a pawl member that engages and controls the rotation of the driving collar. The pawl member includes a pusher pad positioned on and movable along a top of the lid plate. A retention block is set at the side of the pawl member opposite to the driving collar to apply a biasing force to the pawl member through a push bar. In this arrangement, the push bar will not get lost when the pawl member disengages from and thus releases the driving collar for replacement.

Abstract: The present invention relates to a drive rod structure of a tool lock device, and more particularly, to a drive rod with the features of easy to be fabricated, finned structure strength and everlasting color. The drive rod comprises a metal rod body and a push head, where the mental rod body is pre-manufactured with a ball-containing groove and an arc-concaved guide edge at one end, and then the opposite end of the rod body is disposed in the push head mold with plastic push head material. The drive rod is formed by one-shot plastic injection combining the plastic push head and the metal rod body. Thus, it can solve the present drive rod problems, which are not easy to be fabricated and have weak structure strength, and reach the features of easy to be fabricated, firmed structure strength and everlasting color. Eventually, the present invention cannot only increase the convenience of the manufacturing and the economic benefits, but only prolong the usage life effectively.
