摘要： An apparatus for removing lug nuts for changing a tire on a vehicle has a bracing structure and at least three arms connected to the bracing structure. A first arm extends upward and a second arm, adapted to operate as a footrest, extends outward and both arms are positioned such that one may stand on the second arm to generate extra torque while grasping the first arm for stability. A third arm is adapted to receive a socket and is oriented along the socket's axis of rotation. All arms are collapsible for storage.

摘要： A socket having a working end with a work piece aperture that is adapted to receive a work piece and an opposing drive end adapted to engage a torque application tool. The socket includes a biasing member adapted to apply a biased frictional force to the work piece received in the work piece aperture and including first and second opposing ends, where the first end is restricted from moving in the radial direction, and the second end includes a bent portion and is restricted from moving in the axial direction, and a groove formed in an internal surface of the work piece aperture. The bent portion engages the groove.

摘要： The invention relates to a locking device (300) comprising: a shaft (24) comprising a first thread (22); and a nut (12) and a ring (13) to be assembled on the shaft; the nut comprising a first inner thread (18) defining a first radial clearance with the first thread of the shaft; the nut further comprising a second inner thread (20) in the opposite direction to the first inner thread, the ring (13) comprising a second thread (40) defining a second radial clearance with the second inner thread of the nut; the ring comprising a third inner thread (38) defining a third radial clearance with the first thread of the shaft. The inner threads and the first and second threads have an identical and constant thread pitch; and each of the second and third radial clearances is greater than the first radial clearance.

摘要： An inner C-shaped retaining ring assembly includes a base member having an inner peripheral surface that defines a receiving space and an annular retaining groove, and an outer peripheral surface having at least one aperture communicating with the retaining groove. An insert member has at least a portion received in the receiving space. A C-shaped retaining ring is elastically disposed in the retaining groove to prevent removal of the insert member from the receiving space, and is configured to be acted upon by an external force through the aperture to elastically deform toward the receiving space and form an insertion gap with the inner peripheral surface.

摘要： A three-axis limiting tool placement device includes a basic face having a placement area, and a tool placement track assembled in the placement area, wherein there is a three-axis limiting tool placement device in the placement area. The tool placement device includes a limiting part and an elastic hook fastener. The limiting part includes an abutment wall, two lateral limiting walls and a pressing edge to form axially limiting function of X, Y and Z axes of the first end of tool placement track. The elastic hook fastener includes an elastic arm and a hook-shaped portion formed with a dial control portion and a pressing surface. The pressing surface is pressed against the second end of the tool placement track to form a Z-axis limiting function. In addition, there is a corresponding relationship between the elastic arm and the second end of the tool placement track along the X axis.

摘要： A hand tool includes a body provided with a mounting portion. The mounting portion includes six first recessed portions, six second recessed portions, and six locking faces. Each of the first recessed portions includes two grooves. Each of the second recessed portions includes two first arcuate faces and a second arcuate face. Each of the locking faces has a planar shape and is arranged between two of the second recessed portions. Each of the first recessed portions is arranged on one of the locking faces. The locking faces define an imaginary hexagonal portion having six sides coinciding with the locking faces respectively. The mounting portion of the body is mounted on a screw member. The screw member has six ribs received in the second recessed portions. Each of the ribs rests on one of the first arcuate faces.

摘要： Exemplary embodiments are disclosed of backup tools. In an exemplary embodiment, a backup tool generally includes a socket configured for receiving a nut of a flanged connection; a release nut; and an arm extending generally between the socket and the release nut. The arm defines a reaction surface configured to abut against at least a portion of the flanged connection for holding the nut against rotation when a bolt or another nut on a stud is being rotated relative to the nut within the socket of the backup tool, to thereby tighten the flanged connection.

摘要： A self-reacting center wheel nut assembly includes a reaction ring (120) formed between a center wheel nut (110) and a lock collar assembly (130). The self-reacting center wheel nut assembly may also include a washer (140) and O-rings. The self-reacting center wheel nut assembly improves and simplifies wheel bolt tightening; uses the lock collar assembly as a reaction point by transferring opposing torque generated during installation and removal through the reaction ring, which is reacted on by a dual sleeved drive assembly; may be used with HYTORC electric battery powered torque multiplier gun/tools to deliver quick, accurate and precise torque; eliminates the need for external reaction points such as the rim or ground, thereby eliminating side loads and damage to the wheel; is fully sealed and lubricated; eliminates vehicle movement and the need to lock the brakes; reduces operator fatigue, chances of injury and saves operator time and energy.

摘要： A tool adapted for use with a diffuser cartridge and a fluid container, wherein the tool is adapted to facilitate insertion and removal of the diffuser cartridge to and from the fluid container. The tool includes segments that can be separated for shipping or storage and assembled into a tool for removing and inserting a diffuser cartridge. The segments of the tool interlock using a complementary tongue and groove structures. The bottom element that engages the diffuser includes a tongue that engages a middle element having a groove. The middle element also has a tongue that engages a top element having a groove.
