A display pack having a rotatable security member includes a board and the rotatable security member wherein the board has a first hole and a second hole respectively defined therein and an inverted U-shaped frame extends perpendicularly from a front surface of the board with the second hole being located between two extending portions of the inverted U-shaped frame. The second hole has a toothed inner periphery and the rotatable security member includes a polygonal head and a shank which has a flange extending from a free end thereof and a toothed periphery defined in an outer periphery near the flange so that the rotatable security member is rotatably inserted into the second hole with the toothed inner periphery engaged with the toothed inner periphery. A ratchet tool is engaged with the rotatable security member and can be operated within a limited angle between the two extending portions of the frame.

A tool holder includes an upper end wall, a lower end wall, two lateral walls each having an upper portion, and a bottom wall. The lower end wall includes a number of spaced first notches defined therein and spaced along a lengthwise direction thereof. A wall defining a portion of each notch includes a retaining end edge formed on a distal end thereof for securely retaining an end of a tool. A restraining member is removably mounted to the lower end wall to prevent the tool held by the tool holder from being removed. The restraining member includes a number of second notches respectively aligning with the first notches and through which the other end of the tool extends.

Portable tool holder with theft prevention

A pair of pliers includes a handle member having an intermediate portion slidably engaged in an intermediate portion of another handle member which has a rack located closer to the handle end. A pawl is pivotally secured on the handle member for engaging with the rack so as to secure the intermediate portions of the handle members together when the jaw ends are engaged with the workpiece. Two panels and a plate are pivotally mounted between the first and second handle members, and a torsion spring is mounted between the two panels to provide a reliable operation.

Pliers for gripping workpieces of different sizes

A hand tool rack includes a first end adapted to be hung up to a wall, a second end, and a planar base between the first end and the second end. A stop is formed on the planar base adjacent to the first end of the hand tool rack. First and second fixing blocks are formed on the planar base and respectively adjacent to first and second lateral sides of the rack. A plurality of laterally equi-spaced mediate fixing blocks, holding members, and posts are mounted on the planar base and between the first and second fixing blocks. Each mediate fixing block is in alignment with an associated holding member and an associated post. Each holding member includes a protrusion projecting from an upper portion of a vertical wall thereof.

A pair of pliers includes a handle member having an intermediate portion slidably engaged in an intermediate portion of another handle member which has a rack located close to the handle end. A pawl is pivotally secured on the handle member for engaging with the rack so as to secure the intermediate portions of the handle members together when the jaw ends are engaged with the workpiece. The intermediate portions of the handle members have no slots such that the strength of the handle members can be greatly increased.

A ratchet wrench includes a ratchet wheel and a pawl engaged in a head portion. The ratchet wheel includes a number of curved and concave teeth formed in the outer peripheral surface, and the pawl includes a number of curved and convex teeth for engaging with the curved and concave teeth of the ratchet wheel so as to strengthen the engagement between the teeth. In addition, the teeth of the pawl are all engaged with the teeth of the ratchet wheel such that the engagement between the ratchet wheel and the pawl is further strengthened.

A socket wrench extension includes an axial bore for receiving a rod and includes an opening and an orifice for receiving a ball and an actuator. The actuator includes a tapered surface for moving the rod inward of the axial bore. The rod includes an aperture for engaging with the actuator and a cavity for receiving the ball. A spring biases the rod to move the ball partially outward of the opening so as to engage with a socket member. The ball is received in the cavity when the rod is moved inward by the actuator. The elements may be easily assembled in the extension.

Tool holder for wrenches

A tool holder includes two panels having a bottom portion coupled together by a base so as to form an erectable triangular configuration. One of the panels includes a number of cavities for receiving tools. The other panel includes a number of covers temporarily secured to the other panel and disposed according to the cavities for temporarily covering the cavities so as to retain the tools in the cavities. The cavities are inclined so as to stably retain the tools when the covers are disengaged from the panel.

Tool holder

A latch device may secure a cover to a base of a case. A groove and a boss are formed in the base, and another groove and another boss are formed in the cover and aligned with the groove and the boss of the base. aperture formed in the first groove. The latch device includes a cylinder rotatably engaged in the grooves, and a ring secured to the cylinder for engaging with the bosses and for securing the cover to the base. The cylinder can be stably supported in place and will not be easily damaged.

Latch device for a case

A tool holder for holding tools includes a pair of walls extended forward from a board, a number of pairs of notches are formed in the walls for accommodating the tools. Each of the notches includes two ends, in which a shoulder is formed in one end and the other end is located closer to the board. A number of resilient members are projected forward of the board and each aligned with one pair of the notches, the resilient members project inwards of the notches for biasing the tools against the shoulders such that the tools can be stably held in place.

A tool holder includes two opposite surfaces, a number of openings formed in the tool holder for receiving tools, and one or more projections formed in the tool holder for engaging with the tools so as to retain the tools in the openings, the openings are extended through the tool holder and opened in both of the opposite surfaces such that the tools can be easily reached from either side of the tool holder.
