A basin wrench assembly for manipulating a nut on a faucet water line includes a handle which comprises a first section that slidably engages a second section such that the handle has a telescopically adjustable length. A wrench is pivotally coupled to the handle such that the wrench is pivotable along an axis that is perpendicularly oriented with a longitudinal axis of the handle. In this way the wrench can be positioned to engage a nut on a water line attached to a faucet beneath a counter. The wrench comprises a pair of jaws that is pivotally coupled to each other thereby facilitating each of the jaws to engage the nut.

A pipe wrench includes a fixed jaw with alternatively located first recesses and first driving faces defined in the inner side thereof. A pivotal member is pivotably connected to the fixed jaw and a resilient member is biased between the fixed jaw and the pivotal member. The pivotal member has alternatively located third recesses and second driving faces. A hexagonal space is defined between the first and second driving faces. The end portion of the pivotal member is inserted into a second recess defined in the inner side of the fixed jaw. The object is clamped in the hexagonal space, and the pivotal member can be pivoted away from the fixed jaw. The pipe wrench is able to quickly clamp and dismounted from the object.

A supersonic air knife having a compressor and a barrel and nozzle includes an adjustable grasping handle assembly forming barrel handle comprising i) a pair of clasping elements, each clasping element having two gripping surfaces configured to engage the barrel at a point of engagement, with one point of engagement on each side of a first centerline of the barrel; ii) a pivot pin coupling the two clasping elements together on one side of the centerline of the barrel; and iii) A handle with a threaded element engaging the pair of clasping elements configured to draw the clasping elements together around the barrel.

A jaw wrench includes two first bodies, a second body a function end unit and a control unit. The first bodies each have a first toothed hole. The second body has a second toothed hole. The function unit includes a third body and a fourth body pivotably connected to the third body. The third body has a first toothed portion and is connected to the second body. The fourth body has a second toothed portion. An object is clamped between the first and second toothed portions. The control unit has two control members, two second resilient members and two covers. The two control members extend into the two first and second bodies and each have a third toothed hole which is engaged with the first/second toothed hole. When the control members are pushed, the third toothed holes are disengaged from the first toothed hole.

A wrench includes a first part, a second part and a third part. The first part has a first toothed portion and a first pivotal portion. The second part has a third pivotal portion which is connected to the first pivotal portion so that the second part is pivoted an angle relative to the first part about the first pivotal portion. The third part is movably connected to the second part and has a second toothed portion which faces the first toothed portion so that objects of different sizes are clamped between the first and second toothed portions.
