A medical device has a first hinge part (17) including two hinge arms (15, 16), which are arranged at a distance apart, and a hinge pin (32; 52), which is extended between the hinge arms along a longitudinal axis (38; 55). A second hinge part (18) is in certain areas accommodated between the two hinge arms and is passed through by a hinge cavity (31; 51). The hinge pin is accommodated in a pivotably movably in the hinge cavity. The hinge pin and the hinge cavity have a central contact region (33; 56) with contact between hinge pin and hinge cavity. Clearance regions (36, 37; 57, 58) border the contact region on both sides and are extended up to the hinge arms, without touching contact between hinge pin and hinge cavity, in order to ensure an exclusively central force transmission between the hinge pin and the hinge cavity.

A mounting fixture for positioning a workpiece in a desired relationship with an apparatus including an articulation joint for coupling first and second tubular members in a desired angular relationship. The articulation joint includes a first end portion clamped to an interior surface of the first tubular member and a second end portion clamped to an interior surface of the second tubular member. First and second clamping members of the articulation joint are clamped together to prevent pivotable movement between a first articulation member and a second articulation member of the articulation joint.

A locking connector assembly is configured to securely connect a first component to a second component. The locking connector assembly may include a female connector having first and second female ends and a longitudinal passage defined therebetween, and a male connector having first and second male ends. Either of the first or second male ends may be configured to mate with the female connector at either the first or second female ends in order to securely connect the male connector to the female connector.

A replaceable bearing insert may include a bearing surface including a curvature configured to be complementarily contoured to a trunnion ball. The bearing surface may be configured to be in confronting engagement with the trunnion ball. An outer surface opposite the bearing surface may be configured to be received in confronting engagement with an inner surface of an adapter. A first semi-annular flange may extend radially outwardly beyond the outer surface. A second semi-annular flange may extend radially outwardly beyond the outer surface. The first semi-annular flange and the second semi-annular flange may be configured to extend along a first side and a second side of the adapter, respectively, such that the inner surface of the adapter is positioned between the first semi-annular flange and the second semi-annular flange.

A joint structure has a first main body, a positioning pin, a second main body, and a controlling button. The first main body forms with an annular wall and a limiting groove, and the annular wall forms an engaging passage. The positioning pin is mounted in the first main body. The second main body has a limiting protrusion and is rotatably mounted on the first main body; the limiting protrusion is mounted on the limiting groove. The controlling button is mounted on the second main body and forms a positioning groove and an engaging block corresponding to the engaging passage. The positioning pin can abut the positioning groove. With the cooperation of the positioning groove and the positioning pin, the joint structure can be folded or unfolded easily.

The present invention provides a bicycle seat post with one end thereof having a rail support for securing two rails of a bicycle seat. The rail support comprises an accommodation member having an aperture, an adjusting member detachably engaged within the aperture of the accommodation member, and the adjusting member having at least one displacement hole, and a first clamp assembly and a second clamp assembly disposed on two sides of the displacement hole of the adjusting member to secure the two rails of the seat. The rotational mechanism of the present invention is designed with the displacement hole being disposed within the adjusting member, therefore facilitating the rotary adjustment of the seat by adjusting the position of the displacement hole and securing the relative position of the first and second clamp assemblies.

Fully rotating rotary actuator of a multi-purpose machine in which an axle supports the frame of a felling head by a bearing mount, there being a rotary mechanism driven by a rotary motor between the axle and the frame, and in which the connection of the axle includes rotatable joints, the axle includes conduits for electrical cables and a processing fluid line, and in which an additive fluid line tube is arranged in the conduit in the axle and connected to its lower end is a rotatable connector, which is connected to a second tube fastened in the frame for the application of the additive fluid.
