A constant velocity universal joint includes an outer joint member and an inner joint member between which torque is transferred through intermediation of balls while allowing angular displacement. A power transmission shaft is coupled to the inner joint member to allow torque transmission therebetween. A mounting and dismounting mechanism configured to mount and dismount the power transmission shaft to and from the inner joint member is provided between the inner joint member and the power transmission shaft. The mounting and dismounting mechanism includes a tubular member, a snap ring mounted inside the tubular member, a pushing member arranged on a radially outer side of the snap ring to be movable in a radial direction, and an annular member arranged on an outer peripheral surface of the tubular member to be movable in an axial direction.

A coil spring for use in a cavity, such as in a groove of a pin, a housing, or both. The cavity can also be part of a seal assembly. The coil spring can have a longitudinal component positioned within the plurality of interconnected coils that runs along the spring coil axis in order to increase rigidity of the coil spring. The longitudinal component applies a load against the coil spring and/or provides restriction against the coil spring taking a shape or size different than that of the coil spring retaining groove.

A quick release device of a hand tool includes: a main body; an operating portion, including a slidable sleeve movably disposed around the main body and a pin radially inserted into the slidable sleeve, the operating portion further including a movable rod movably disposed in the main body, the pin connected with the movable rod; an annular plastic body, rotatably disposed around the slidable sleeve and corresponding to the pin, a stepped structure formed between the slidable sleeve and the annular plastic body; an identification portion, disposed around the annular plastic body; wherein the slidable sleeve is movable between first and second positions, when the slidable sleeve moves toward the first position, the pin drives the movable rod to move toward a fixing position; when the slidable sleeve moves toward the second position, the pin pushes the movable rod to move toward a releasing position.

A locking pin with a locking mechanism (8, 27, 28) that has a guide sleeve (3) that can be attached to a machine part, and a pin (2) connected to an actuator button (6), which passes through a central bore (14) in the actuator button (6), and which can be axially displaced and secured in a hole in the guide sleeve (3) counter to and by means of the force of a compression spring (7) by actuating the actuator button (6), wherein the pin (2) can be brought into at least two locking positions in the guide sleeve (3) by means of the locking mechanism (8, 27, 28) located in the central bore (17), wherein the locking mechanism (8, 27, 28) is sealed in the central bore (14) of the actuator button (6) in the region of a second guide sleeve (12) that is coaxial to the first guide sleeve (3) and connected thereto, and is composed of a locking sleeve (8) secured to the actuator button (6), the sleeve extension (15) of which forms a locking contour (28) in conjunction with a locking recess (27) located in the region of the second guide sleeve (12).

A locking pin assembly having a body including a wall defining an interior space and having at least one aperture therethrough for allowing fluid communication between the interior space and an exterior environment. A barrel defines a bore and has an outer wall with external threads. A pin travels longitudinally within the interior space of the body and the bore of the barrel. A spring actuated assembly maintains an end of the pin in an extended position relative to an end of the barrel when no force is applied to the pin and allows the pin to retract relative to the end of the barrel when a force is applied to the pin.

An improved plunger for a self-locking pin having a plunger section and a base section in a unitary one-piece construction, wherein the plunger section is at least substantially orthogonal to the base section. Wherein the base section comprises at least a substantially planar configuration, and may provide for biasing of the plunger section. A portion of the plunger extends outwardly from a bore of the self locking pin in which the plunger resides. The plunger section is preferably wedge-shaped, or may possess other geometrical shapes, while the portion of the plunger disposed inside the bore is of a cylindrical shape. An extended biasing section tor positioning of the plunger section may be in unitary construction with the base section.

The present disclosure provides a connecting device and a pipe press-fit connecting apparatus using the connecting device. The connecting device may be used to connect a connected unit to a pressing power providing unit. The connecting device includes a fastener and a coupling pin. The fastener is installed at one end of the installation hole on an exterior surface of a cylinder block and has a fastening pin configured to be resiliently arranged and at least partially be exposed to the installation hole. The coupling pin is inserted through the installation hole and the insertion hole through another end of the installation hole on the exterior surface of the cylinder block to be resiliently coupled to the fastening pin to couple the connected unit to the pressing power providing unit.

A method of making a connector assembly includes attaching two stamped housing sections together to form a connector housing having a housing groove with a groove bottom and two side walls and providing the connector housings with a spring used as a mechanical connector and/or as an electrical connector for numerous applications and across numerous industries. The groove geometries can easily be altered using different stamping dies.
