A hand tool is provided, including: a first member; a second member; a shaft, connected with the first member, rotatably inserted to the second member, including positioning slots; and a control member, disposed on the second member, including at least one tooth; wherein the control member can be released by disengagement of the at least one tooth from the positioning slots so that the first and second members are rotatable relative to each other, and the control member can be locked by engagement of the at least one tooth within at least one of the positioning slots so that the first member is non-rotatable relative to the second member; wherein when the at least one tooth is engaged within at least one positioning slot, at least one blocking wall of the tooth is in gapless surface contact with at least one side wall of the slot.

A tool for rotating an object includes an assembly comprising an inner ring and an outer ring wherein each of the rings include multiple components which can be moved relative to one another between a first condition which accommodates the positioning of the assembly about the object to be rotated and a second condition at which the multiple components of each of the rings form the annular shape of the inner or outer ring to which the multiple components correspond. When the rings are arranged in the second condition, the inner ring is capable of rotating relative to and within a radial plane of the outer ring. In addition, a gear arrangement is connected to the assembly for transferring rotational forces applied from a power tool to the inner ring so that rotation of the inner ring relative to the outer ring effects the rotation of the object desired to be rotated.

A wrench assembly, and methods of making and using such a wrench assembly, whereby the wrench assembly includes a head, an opening disposed within the head, a first pivotal member coupled to the head, a plurality of radial slots inwardly extending into the first pivotal member, and a handle, whereby the head pivotally couples to the handle.

A unidirectional ratchet wrench structure has a wrench member, a pawl and a ratchet. The wrench member has an accepting space for accommodating the ratchet and an accepting space for accommodating the pawl. A toothed section of the pawl has a plurality of equiangular teeth and an irregular tooth. Since the irregular tooth is lower than the height of the equiangular teeth, the irregular teeth irregular tooth is capable of quickly disengaging from the equiangular teeth of the ratchet. The arc section and the toothed section have different arc measures and not push against the outer periphery of the ratchet at the same time, through the abutment of the pivoting point and the change of the center of gravity of the pawl when the wrench is rotated, the pawl is capable of producing a seesaw yaw movement to achieves the effect of quick engagement and disengagement.

A pivoting head wrench apparatus for use in confined areas includes a handle having a handle top side, a handle bottom side, a handle first end, a handle second end, a handle front edge, and a handle back edge. A first wrench head is coupled to the handle. The first wrench head is pivotably coupled to the handle first end and is sized to a standard metric size. A second wrench head is coupled to the handle. The second wrench head is pivotably coupled to the handle second end and is sized to a standard SAE size.

An angle adjustment structure for pressing a hand tool contains: a first handle, a second handle, a spring washer, a return spring, two pressers, and two fasteners. The first hand includes a contact sheet having a first thickness, a first toothed orifice, and a positioning portion. The second handle includes a groove having a second thickness, two fixing plates, a second toothed orifice, and a trench. A profile of the second toothed orifice is identical to a profile of the first toothed orifice. The return spring is defined the two pressers. A respective presser includes a pressing portion, a slot, a notch, a toothed column, and a fixing portion. A respective fastener is engaged between the second handle and the respective presser to limit the respective presser to operate among the second toothed orifice, the trench, the recess, and the first toothed orifice.

A tool assembly designed to couple to a torsion spring and torsion rod to wind and unwind the torsion spring on the torsion rod. The tool assembly includes a variety of components in mechanical communication with one other to rotate the torsion spring. Specifically, the assembly includes a worm gear in mechanical communication with a ring gear and a set of brackets securable to a torsion spring. Between the ring gear and the brackets are a series of plates arranged and assembled on a base, providing a singular device within the assembly that a user can grip to manipulate a torsion spring in a safer manner than possible in the prior art. A drill or other device can couple to attachment points in mechanical communication with the worm gear to rotate the worm gear at a greater rate, thereby reducing the winding and unwinding time of the torsion spring.

An anti-slip torque tool with integrated engagement features includes a torque-tool body and a plurality of engagement features. The plurality of engagement features is radially distributed around a rotational axis of the torque-tool body. Each of the plurality of engagement features includes a first cavity surface, a first bracing surface, a second bracing surface, and a second cavity surface. The first bracing surface and the second bracing surface are adjacently connected to each other through an intersection point. The first cavity surface is terminally connected to the first bracing surface through a first connection point as the first bracing surface is positioned in between the second bracing surface and the first cavity surface. The second cavity surface is terminally connected to the second bracing surface through a second connection point as the second bracing surface is positioned in between the first bracing surface and the second cavity surface.
