Abstract: An adjustable wrench includes a handle including a notch defined therein. A driving head is pivotally fixed to the handle for engaging an object that is driven by the adjustable wrench. The driving head and the handle include first and second springs engaged therebetween. The first and second springs each include a first end abutting against the handle and a second end abutted against the driving head, respectively. The notch receives the first and second springs. Coils of the second spring are disposed within a space delimited by coils of the first spring. One of the first and second springs is coiled clockwise from the first end to the second end thereof, and the other of the first and second springs coiled counterclockwise from the first end to the second end thereof.

Abstract: An open-end wrench for quickly turning an object includes a driving end including a first jaw and a second jaw which cooperate together. One of the first and second jaws includes a recess defined therein. Further, a movable engaging member includes a body pivotally fixed in the recess by a pivot. The body is in a surface contact with a lateral wall of the recess, and the recess supports the body. The pivot is inserted through the body and is fixedly engaged with a wall of the recess. Further, an elastic member resiliently engages with the movable engaging member. Furthermore, the open-end wrench is turned in a first turning direction to turn the object and in a second turning direction to move relatively to the object.

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 wrenching device includes a driving member, a hole and at a slit defined therein, and defines an engaging portion. The slit communicates with the hole. The wrenching device further includes an actuating member moveably disposed in the hole of the driving member, and a control member including a connecting end pivotally joining to the actuating member and including first and second engaging sides selectively abutting against a wall defined on the driving member in response to first and second operating positions thereof, respectively.

Abstract: An adjustable wrench includes a fixed jaw, a movable jaw, and a handle. The fixed jaw includes a chamber and a hole defined therein. An adjusting mechanism and an abutting mechanism are disposed in the chamber. The adjusting mechanism includes a worm gear and a fixing member. The abutting mechanism includes an abutting member.

The adjustable wrench is operable in a first direction wrenching an object and includes the worm gear stopped from moving along the fixing member by the abutting member fixedly abutting against the worm gear. The adjustable wrench is operable in a second direction moving relative to the object and includes the worm gear adapted to be moved with respect to the fixing member and including the movable jaw moving with respect to the fixed jaw and the abutting member not fixedly abutted against the worm gear.

Abstract: An improved redirection structure of a ratchet wrench is disclosed. A driving head accommodates a connector body that has a knob. The accommodating room of the connector body accommodates a brake block with a notch. The urging element of the knob urges against the brake block in the notch.

Abstract: A ratchet wrench includes a driving end including a ratchet member, two pawls releasably and selectively engaging with the ratchet member for setting the ratchet wrench in two operation modes, and a switching mechanism disposed between the pawls. The switching mechanism includes limits urging the respective pawls such that one limit engages with one pawl to urge it to disengage from the ratchet member while the other limit disengages from the other pawl to allow it to engage with the ratchet member in one operation mode, and the other limit engages with the other pawl to urge it to disengage from the ratchet member while the one limit disengages from the one pawl to allow it to engage with the ratchet member in another operation mode. Additionally, the pawls are prevented from being mis-shifted by the switching mechanism.

Abstract: A movable wrench including a screw bar, and an operating element. The bottom surface of the screw bar is urged by a first compressible spring. The hook part of the operating element urges against the bottom surface of the screw bar. As the user depresses the operating end of the operating element, the hook part escape from the bottom surface. The first compressible spring is depressed downward. After the reverse rotation and positioning, the first compressible spring urges against the screw bar again. The operating end is released so that the hook part urges against the bottom surface again.

Abstract: An adjustable wrench with a ratchet function comprises a fixed jaw 1 and a movable jaw, wherein the fixed jaw has a receiving recess for receiving a screw, a first spring is disposed between the screw and the inner wall of the receiving recess, a shaft is passed through the first spring and the screw, the shaft is formed thereon with a blocking portion for catching a pin, an actuating portion protrudes from the end of the pin, the actuating portion of the pin abuts against the V-shaped push surface of an operating piece, and when pressing one of the ends of the operating piece, the actuating portion of the pin can be pushed by the V-shaped push surface so that the pin moves and disengages from the blocking portion of the shaft. At this time, the wrench can be counter-rotated to quickly perform screw locking action.
