Abstract: An adjustable spanner for quickly turning an object includes a moving member, a first jaw, a second jaw, and a grip. The moving member is movably joined to the grip. The first jaw is adjustably jointed to the moving member. The second jaw is pivotally joined to the grip and cooperates with the first jaw to clamp the object. A user grasps the grip when using the adjustable spanner.

Abstract: A ratchet wrench comprises a body, a ratchet, a first pawl, and a second pawl. Each of the first pawl and the second pawl can move between a first position and a second position relative to the ratchet. The first position is a position where the ratchet wrench can transmit torque to said driven element from respective first pawl or second pawl, and the second position is a position where no torque is transmitted from respective first pawl or second pawl. A control member can pivot or rotate to stay in one of a first position, a second position, and a neutral position for different operations. The body has an operating part comprising a groove. The groove comprises two accommodation chambers having inclined surfaces and can accommodate the first pawl and the second pawl.

Abstract: A ratchetable open-ended wrench includes a handle H for a hand to grasp, a wrench head 100 located on one end of the handle, and a fastener room 160 located in the wrench head 100 for accommodating a workpiece W to be rotated. The wrench head 100 further includes a first jaw 110 having a first driving wall 114, a second jaw 120 having a second driving wall 124 facing the first driving wall 114, an inner wall 126 extending from the second driving wall 124 into the second jaw 120, a fastener-jaw room 128, an auxiliary jaw retracting opening 13, an auxiliary jaw 140 capable of longitudinally sliding into the auxiliary jaw retracting opening 130 in an elastic way, and an auxiliary jaw limiting member 150 coupled to a limiting slot 148. The auxiliary jaw 140 further includes an exterior end 142 having a pillow 142 in contact with the driving wall 126 and a pushing surface 144 for working together with the first jaw 110 to grip the workpiece W under operation, an interior end 146, and a limiting slot 148.

Abstract: A ratchet wrench includes: a head portion defining a first compartment and a space below; a driving head having an annular driving tooth portion; and first and second detents, each having ratchet teeth to engage the annular driving tooth portion. The first and second detents move laterally between first and second sides of the space simultaneously. When the first and second detents are on the first side, the wrench idle rotates back-pulling along a first direction. When the first and second detents are on the second side, the wrench idle rotates back-pulling along a second direction. Radial alignment diverges between the ratchet teeth of the first detent and the second detent, so that only one of the detents engages the annular driving tooth portion. The other detent is urged against the annular driving tooth portion. When the wrench idle rotates back-pulling, the ratchet teeth of the first and second detents engage with the annular driving tooth portion alternately.

The wrench head further includes a first jaw having a first driving wall, a second jaw having a second driving wall facing the first driving wall, an inner wall extending from the second driving wall into the second jaw, a concavity, an auxiliary jaw retracting opening, an auxiliary jaw capable of longitudinally sliding into the auxiliary jaw retracting opening in an elastic way, and an auxiliary jaw limiting member coupled to a limiting slot. The auxiliary jaw further includes an exterior end having a pillow in contact with the driving wall and a pushing surface for working together with the first jaw to grip the workpiece under operation, an interior end, and a limiting slot.
