A pack for carrying personal effects and protecting such effects from damage caused by contact with moisture is provided. First, a flexible and rugged water-resistant outer container having a resealable opening defines a cavity sized to receive a waterproof pouch along with various other items. Next, the waterproof pouch may have an opening to receive various items. A first means and a second means for sealing the waterproof pouch are successively spaced away from the opening of the pouch. Then, once sealed, a portion of the pouch may be successively folded over the first and second means for sealing the pouch to further reduce any risk that moisture enters the pouch through the sealed opening. Finally, means may be provided for securing the folded portion of the pouch in place to provide nested and redundantly sealed compartments.

A case for an electronic device with a retractable stand may support the case for an inserted electronic device when disposed in a horizontal and/or vertical position. The case may be transitioned from the horizontal and/or vertical disposition and vise-versa without changing the relative positions of the case and the stand to one another.

A reversible monkey wrench includes a handle, a head, a slidable jaw, an axial rod and a worm gear. The handle has a connecting end for the head to abut thereagainst. The head is formed with a fixed jaw, a sliding rail, a receiving slot and a connecting bore. The connecting bore communicates with the receiving slot. A movable pin and a spring are disposed between the connecting end and the head. A top of the movable pin selectively inserts through the connecting bore. The spring urges the movable pin so that the movable pin may abut against the connecting end. The worm gear is adapted to control the slidable jaw to move and is slidably disposed in the receiving slot with respect to the axial rod. The movable pin selectively abuts against the worm gear to prohibit the worm gear from sliding.

A reciprocatable open end wrench comprises a swing member allowing to slide relative to a concave arcuate surface of a second jaw, the radius of a convex arcuate surface of the swing member is equal to that of a concave arcuate surface of the second jaw, and between the concave arcuate surface and the convex arcuate surface is provided with an engagement structure having a slot member and a peripheral protrusion so as to engage with each other. Besides, the reciprocatable open end wrench further includes a stop portion for resisting against the torque of the swing member, thereby enhancing the strength and preventing the related components to be damaged.

A monkey wrench includes a handle, a head, stationary jaw, a movable jaw and a jaw-moving element. The head is formed at an end of the handle and made with a side, a groove in the side and an opening in communication with the groove. The stationary jaw is formed on the head and made with a first nut-contacting face, a second nut-contacting face next to the first nut-contacting face, a bulge on the first nut-contacting face and a recess next to the bulge. The movable jaw is movably disposed in the groove and formed with a nut-contacting face and a bulge on the nut-contacting face thereof. The jaw-moving element is disposed in the opening and engaged with the movable jaw so that the jaw-moving element is operable to move the movable jaw relative to the stationary jaw.

A wrench includes a handle and an open-end with two jaws and each jaw has a driving surface. Each driving surface has a contacting area and two yielding areas. The contacting area is located between the two yielding areas and includes a contact portion and two notches. The contact portion is located between the two notches, and two extension areas each are connected between the yielding area and the notch corresponding thereto. A corner is formed at a joint area of the contact portion and an inside of the notch so as to bite a rounded fastener head. The contact portions are matched with straight sides of a normal fastener head.

A positioning member is used to position the movable jaw to the sliding groove of the adjustable wrench and the adjustable wrench together with the positioning member are applied by vibrate grinding technology so as to make the outer surface of the movable jaw to be a mirror surface and the rod of the movable jaw is kept as the surface condition after being machine. The tolerance between the rod and the sliding groove is controlled within expected range.

A hand tool locking device for a hand tool includes a switch member having a shank which is rotatably inserted in a recess defined in the head of the hand tool and the shank includes a convex and curved surface and a flat surface. A pawl and a spring are received in a passage defined in an inside of the yoke of the head of the hand tool. The pawl has teeth defined in a first end thereof and the teeth are pushed to engage with engaging teeth of the pivotable tool head when the convex and curved surface of the shank pushes a second end of the pawl toward the tool head. When the shank is rotated to let the flat surface to contact the second end of the pawl, the teeth of the pawl are disengaged from the engaging teeth of the pivotable tool head.

A wrench comprises a main body including a handle and a head including a fixed jaw and a groove and a passage which is located parallel to and communicates with the groove, a through hole defined through the head and communicating with the groove and the passage. A mediate member made of metal and integrally connected with the head by using injection, and including a protrusion, a tubular portion and a frame with an opening, the protrusion connected to the fixed jaw, the tubular portion engaged with the groove and the frame engaged with the through hole. A movable jaw made of metal and including a sliding rod slidably received in the tubular portion, a plurality of teeth defined in an underside of the sliding rod. An adjusting member made of metal and engaged with the opening of the frame, the adjusting member engaged with the teeth of the sliding rod.
