Abstract: A ratchet wrench includes a head. A gear wheel, a first pawl, and a second pawl are disposed in a chamber defined in the head. The gear wheel has an outer periphery thereof including a plurality of teeth extended circumferentially outwardly therefrom. The first and second pawls each include a lateral side thereof including third and fourth plurality of teeth respectively extended outwardly therefrom. The first and second pawls are disposed one above the other. The first and second pawls are respectively biased by first and second biasing mechanisms. The first and second pawls are alternatively engaged with the gear wheel when it is operably turned.

Abstract: A driving end of a tool includes a body including a chamber and a bore. The chamber includes first and second pawls disposed therein. A first engaging member is rotatably disposed in the chamber and defines a first engaging section with a plurality of teeth. A second engaging member is rotatably disposed in the chamber and defines first and second engaging areas. The first engaging section is engaged with the first engaging area. The first and second engaging areas are selectively engaged with the first and second pawls. A switch includes an activating member inserted through the bore and received in the second engaging member and operably rotatable to first and second positions selectively.

Abstract: A ratcheting wrench includes a driving head including at least one fixed jaw, a groove and a hole. The groove connects to the hole. The groove extends along a first axis. The hole extends along a second axis. The first axis deviates from the second axis. A jaw plate defines a connecting section and includes a cavity. The connecting section engages and is slidable in the groove. The cavity extends in the connecting section and connects with the hole. A biasing device includes a restraining member and a biasing member. The biasing member engages in the hole and the cavity. The restraining member engages in the cavity. The biasing member abuts against the restraining member and a periphery of the cavity and restrained therebetween.

Abstract: A ratchet wrench includes a head. The head delimits a receiving space and a recess. The recess connects with the receiving space. The recess delimits an opening adjacent to the receiving space. A gear wheel is disposed in the receiving space and includes an outer circumference defining a first engaging area. A pawl mechanism is restrained in the recess and includes a surface defining a second engaging area facing and in ratcheting engagement with the first engaging area. A groove is defined on the outer circumference of the gear wheel. The pawl mechanism engages with the groove and restrains the gear wheel in the receiving space.

Abstract: An adjustable wrench includes a handle, a head, a slidable jaw. The head is formed at one end of the handle and includes a fixed jaw, a sliding rail, and a receiving slot. The slidable jaw is slidably disposed in the sliding rail and includes a gripping portion and a reinforced portion. The reinforced portion is formed at a side edge of the gripping portion. The gripping portion has a gripping surface, and the reinforced portion has a first reinforced surface. The first reinforced surface is connected with the gripping surface to form a first included angle greater than 90 degrees. A worm gear is received in the receiving slot and engaged with the slidable jaw.

Abstract: A tool bit includes a plurality of fins each having first and second ends and extended radially and longitudinally and including the second end thereof forming two opposite lateral sides each including a reinforcing section extended therefrom. Two adjacent fins of the plurality of fins form a recess therebetween, which has a curved periphery interconnecting two adjacent reinforcing sections of the two adjacent fins. Each fin defines a first length from the end thereof to the curved periphery of the recess extended from the second end thereof. The first length is smaller than a second length defined between two opposite peripheral sides of a hexagonal periphery of a connecting end of the tool bit.
