Abstract: A wrench includes a lever with teeth formed on the wall of a space defined therein. A handle includes teeth formed on the wall of a space defined therein. A toothed wheel is movable in the spaces between a first position where the teeth of the toothed wheel are engaged with the teeth of the lever and handle and a second position where the teeth of the toothed wheel are only engaged with the teeth of one of the lever and handle. A switch is operable for moving the toothed wheel between the positions. A boss is formed on the handle. A groove is defined in the switch. The arrival at the first position is signaled by the contact of the boss with an end of the groove while the arrival at the second position is signaled by the contact of the boss with another end of the groove.

Abstract: A one-way monkey wrench includes a handle, a stationary jaw, a movable jaw, a worm and a one-way mechanism. The handle defines a groove, an opening in communication with a section of the groove and a tunnel. The stationary jaw is formed on the handle. The movable jaw is movably installed on the handle, and includes a rack movably positioned in the groove. The worm is rotationally positioned in the opening and engaged with the rack. The one-way includes a tongue movably positioned in the tunnel. The tongue includes an end, a sliding facet near the end and a pushing facet near the sliding facet. The sliding facet slides on an object when the one-way monkey wrench is rotated in a direction. The pushing facet pushes the object when the one-way monkey wrench is rotated in an opposite direction.

Abstract: A bi-sectional wrench includes a lever, a handle and a toothed wheel. The lever includes a space defined therein and a plurality of teeth formed on the wall of the space. The handle includes a space defined therein and a plurality of teeth formed on the wall of the space. The toothed wheel is movable in the spaces between a first position and a second position. The teeth of the toothed wheel are engaged with the teeth of the handle and the teeth of the lever so that the handle and the lever are pivoted by a common angular speed in the first position of the toothed wheel. The teeth of the toothed wheel are only engaged with the teeth of the handle or the lever so that the handle and the lever are pivoted by different angular speed in the second position of the toothed wheel.

Abstract: A bendable wrench includes a handle, a head and a pivot. The handle includes a first ear formed thereon, a second ear formed thereon and a plurality of teeth formed on an internal side of the second ear. The head includes an ear and a plurality of teeth formed on an internal side of the ear thereof. The pivot is movably inserted in the ears so as to pivotally connect the head to the handle. The pivot includes a plurality of teeth that can be engaged with the teeth so as to firmly retain the angle between the head and the handle and disengage from the teeth of the head so that the angle between the head and the handle can be changed.

Abstract: There is disclosed a selective one-way wrench with a device for retaining a socket. The selective one-way wrench includes a handle and a head formed at an end of the handle. The retaining device includes a cover installed on the head. Two parallel grooves are defined in the internal side of the cover. A stop is formed between the grooves. A shackle is put between the cover and the head. The shackle includes two slides sliding in the grooves. The shackle defines an opening larger than the socket. The shackle includes a retaining portion at a front end. An arched leaf spring is compressed between the shackle and the stop. Thus, the shackle is normally at a locking position and will be returned to the locking position after it is moved and released. Because of the above-mentioned design, the socket can easily be retained and released. As the slides slide in the grooves, the operation of the retaining device is smooth. Therefore, its lifecycle is long.

Abstract: There is disclosed a selective one-way screwdriver and, more particularly, a selective one-way screwdriver that includes a long handle and can easily be operated. It includes an elongated handle formed with at least one head formed at an end. The head defines a space for receiving an annular gear formed with a toothed wheel portion on the external side. The annular gear includes a recess in an end in order to receive a bit. The head further defines a cavity near the handle and a channel between the cavity and the space. A switch is put in the cavity. In the channel are put two pawls one of which can selectively be engaged with the toothed wheel portion of the annular gear under the control of the switch. Thus, the handle can drive the annular gear in selective one of two directions. The length of the handle is perpendicular to the axis of the bit so that a user can easily use a small force in order to a large torque through the selective one-way screwdriver.

Abstract: A ratchet screwdriver includes a main rod, a driven shaft, a ratchet mechanism, a socket connector, a control member, and a handle. Thus, the pawl member of the ratchet mechanism is pivoted to engage the ratchet teeth of the socket connector by rotation of the rotation wheel of the control member, so that the ratchet screwdriver is operated easily and conveniently, thereby facilitating a user operating the ratchet screwdriver to drive a workpiece.

Abstract: A oneway ratchet wrench includes a wrench body, a ratchet wheel, and a drive mechanism. The drive mechanism includes a support plate, a oneway pawl member, and an elastic member. Thus, the elastic member is mounted between the support plate and the oneway pawl member, so that the wall of the receiving recess of the drive head needs not to additionally provide a blind hole for mounting the elastic member, thereby facilitating assembly of the oneway ratchet wrench, and thereby decreasing costs of fabrication.

Abstract: A ratchet wrench includes a wrench body, a ratchet wheel, a direction control mechanism, a drive member, a ball, and a quick release mechanism. The quick release mechanism includes a bolt, a movable rod, a press knob, and an elastic member. Thus, the socket is mounted on and detached from the driving head of the drive member easily and rapidly, thereby facilitating a user mounting the socket on the driving head of the drive member and detaching the socket from the driving head of the drive member.

Abstract: A ratchet wrench having a positioning structure includes a wrench body, a cover mounted on the driving head of the wrench body, an elastic plate mounted between the driving head and the cover, and a push plate mounted between the driving head and the cover. The push plate is formed with an arcuate portion having an outer side rested on the elastic plate and an inner side extended into the opening of the cover. Thus, by combination of the elastic plate and the push plate, the socket is combined with the driving head integrally without detachment, thereby facilitating the user operating the ratchet wrench and the socket. In addition, the socket is detached from the driving head easily and conveniently.

Abstract: A ratchet wrench includes a handle, a ratchet wheel, a plurality of adjusting blocks, and an adjusting shaft. The adjusting shaft is rotatably mounted in the working space of the ratchet wheel and has a toothed disk meshing with the outer thread of each of the adjusting blocks, so that each of the adjusting blocks is rotated by rotation of the adjusting shaft to move into the working space of the ratchet wheel so as to adjust the working size of the working space of the ratchet wheel. Thus, the ratchet wrench can be used to operate workpieces of different sizes and specifications.
