A locking assembly for retaining a wear member to excavating equipment has a locking element that is received into an opening in the assembly and is movable about a pivot axis in the opening between a hold position and a release position. The locking element has an outer edge that is generally opposite the pivot axis that opposes a base surface of the opening when the locking element is in the hold position. The outer edge is configured to pull away from the base surface when the locking element is rotated from the hold position toward the release position.

An adapter attachment for an auger which includes an connecting shaft sized and shaped to be attached to the pilot bit hole present in the end of an auger, after the removal of pilot bit. The adapter also includes a bolt flange for connection to a foundation anchor installation plate/tool such as a locking dog assembly. The adapter obviates the need to remove the auger from the Kelly bar during anchor installation. A modification includes eliminating the bolt flange and placing the connecting shaft directly to the locking dog assembly to form a pilot hole locking dog.

A snap connecting device is used to connect an inner tube and an outer tube. The snap connecting device includes an elastic member, and a snapping member mounted on a distal end of the elastic member to lock the outer tube on the inner tube. The snapping member has a side formed with an oblique face. Thus, when the snapping member is pressed inward, the user's one finer only touches the oblique face of the snapping member, so that the user's one finer escapes from the gap defined between the locking hole of the outer tube and the snapping member, thereby preventing the user's one finer from being injured so as to ensure safety of operation of the snap connecting device.

In a device for coupling a tooth onto an adaptor nose with a key, the tooth includes a skirt shrouding the adapter nose beyond the key passage zone and having a configuration connected to a return wall, comprising a bordering ridge. The wall is provided in the width of the skirt and corresponds to the passage and positioning of the key. Proximate the ends of the wall, and in the thickness of the skirt, are provided passage openings for the key devoid of abutting function in operation and ensuring a guiding and stopping function only when the key is inserted or removed. The key comprises two components transversely mobile relative to each other.

A connecting arrangement for an automotive rear wheel steering unit is provided which is adapted for connecting an output shaft of a rear wheel steering gear train and a steering rod for steering rear wheels. The connecting arrangement includes a tapered portion formed on the output shaft, a tapered bore formed in the steering rod for receiving the tapered portion, and a fastener for locking the tapered portion of the output shaft to the tapered bore of the steering rod. With these arrangements, easy connecting operation is established with high mounting accuracy.
