Disclosed is a locking device, comprising an outer sleeve (1) and at least one locking unit (2) located in the outer sleeve (1), wherein the locking unit (2) is formed by connecting a plurality of pressing blocks (3), a gap (5) is provided between two adjacent ones of pressing blocks (3), a rod locking hole (6) is provided in the gap (5), and a set screw hole (7) is provided on the outer sleeve (1) at a position corresponding to the locking unit (2); and when a set screw is screwed into the set screw hole (7) to directly or indirectly press the locking unit (2), the locking unit (2) deforms and drives the pressing blocks (3) to tightly press rods (8, 9) mounted in the respective rod locking holes (6) at the same time.

A differential with a washer for a gear in a differential housing includes an outer edge at a maximum radial distance from an axis, and an inner edge defining an opening, the inner edge defined in part by an innermost portion at a minimum radial distance from the axis and the inner edge having an outward portion spaced radially outwardly from the innermost portion. The washer also includes an axially and radially inclined sidewall extending at least part of the way between the outer edge and the innermost portion.

The present application provides a fastening clamp, used for connecting a first component to a second component having a connecting post. The fastening clamp includes: a substrate on which a mounting hole is provided; at least two first retaining legs, and at least two second retaining legs, where the mounting hole is used to receive the connecting post of the second component, proximal ends of the at least two first retaining legs are connected to an edge of the mounting hole, proximal ends of the at least two second retaining legs are connected to the edge of the mounting hole, and the at least two first retaining legs and the at least two second retaining legs are on the same side of the substrate; where distal ends of the at least two second retaining legs are closer to the substrate than distal ends of the two first retaining legs, and the at least two first retaining legs and the at least two second retaining legs are configured to be able to collectively retain the connecting post of the second component in the mounting hole. The fastening clamp in the present application can be mounted on a cylindrical connecting post.

A quick connection and/or fastening system suited to mutually connect and disconnect a first and a second element is disclosed, the system including a first and a second component that are suited to be rigidly fixed to the first and second elements, respectively, the first component and the second component being also suited to be mutually connected and disconnected, the second component being suited to house an end portion of the first component in such a way as to allow its translation inside the second component, the second component comprising also counteracting elements suited to counteract the translation of the end portion of the first component towards the outside of the second component.
