摘要： A rotary impact assembly structure includes a rotary tool and a rotary impact assembly. The rotary tool is assembled with the rotary impact assembly so that the rotary impact assembly is driven by the rotary tool to rotate. The rotary impact assembly has a counterweight plate. The counterweight plate has a first surface and a second surface at two sides thereof. The first surface is provided with a socket portion having an insertion hole at a center thereof. The second surface is provided with a plug portion at a center thereof. The rotary impact assembly structure is able to increase the rotational inertia and the amount of torque to quickly loosen or tighten a fastener and has a simple and convenient operation.

摘要： A ratchet wrench includes a head with a ratchet wheel rotatably received therein. A positioning unit is located in the head and is cooperated with a pawl which is engaged with the ratchet wheel. A collar is located in the head and has two notches defined in a peripheral wall of the collar. A curved groove is defined through the collar. Two toothed racks are formed along the groove. Two clamp members are located in the ratchet wheel which has two guide slots. Each clamp member has two guide rods which are located in the guide slot corresponding thereto. An engaging unit extends through the groove and is pivotably connected to a lever to securely position the clamp members when clamping an object. The two clamp members are adjusted to securely clamp the object by rotating the collar, and the object can he rotated by the ratchet wrench.

摘要： An adjustable ratchet wrench includes a head with a handle. The head has a space defined therein. A first pawl is located in the head and has a first engaging portion which protrudes through a recess in the inside of the space. A hollow slide is movably located in the space and has a passage defined axially therethrough. An index member extends from the top side of the slide. A second pawl is located in the first end of the slide and has a second engaging portion facing the space. A threaded rod extends through the passage of the slide and outer threads. The slide has an insertion member inserted therein and the insertion member has an engaging part which is engaged with the outer threads. By rotating the threaded rod, the slide with the second pawl move into the space to clamp objects of different sizes.

摘要： A hand tool includes a first part and a second part which is pivotably connected to the first part. The first part has a first jaw. An assistance member is connected to the first part and has a second jaw connected there. The assistance member has an adjustment screw, the second jaw is movable by rotating the adjustment screw. The user uses the first and second parts as the conventional pliers. A locking member is located in the positioning hole of the first part and can lock the relative position of the first and second parts. The second jaw is then adjusted relative to the first jaw by rotating the adjustment screw to be functioned as an adjustment wrench.
