A flexible cardan joint comprises a hollow central longitudinal axis, two hollow pivots mounted orthogonally relative to one another and capable of pivoting respectively about a rotation axis, three axes being mutually orthogonal and intersecting at a point of rotation situated at the center of the cardan joint. Each pivot comprises an annular outer frame extending along a plane containing the central longitudinal axis Z and orthogonal to the rotation axis, a hollow inner ring coaxial to the outer frame and a plurality of sets of flexible blades linked to the outer frame and to the inner ring, and the two pivots are linked together by rigid link parts.

An energy absorber assembly for use with a safety harness comprises a connector, a bracket assembly, a fastener, and an energy absorber. The connector is configured and arranged to operatively connect to the safety harness. The fastener operatively connects the bracket assembly and the connector, and the fastener releases the bracket assembly from the connector when subjected to a predetermined load. The energy absorber operatively connects the bracket assembly and the connector, and the energy absorber includes a first portion and a second portion that separate to absorb shock after the bracket assembly is released from the connector.

The universal connector includes a main rod defining an axial direction, a main body, a positioning member, and a fastening member. The main body has a first through hole, two arms, and a second through hole penetrating through the arms. The main body is sleeved onto the main rod by the first through hole. The positioning member and the fastening member are disposed at two ends of the second through hole respectively. The positioning member forms an aperture for receiving a support of a musical instrument. Angle of the support can be adjusted by rotating the positioning member, and height or direction of the support can be adjusted by moving or rotating the main body. When the positioning member and the fastening member are engaged with each other to fasten the main body and the main rod together, the support is prevented from moving.

A universal joint includes a coupling member having an end for coupling with a tool. A body includes a rounded base pivotably mounted to the other end of the coupling member. The body further includes a drive column spaced from the rounded base along an axis. A reinforcing section is intermediate the rounded base and the drive column. The reinforcing section includes an outer periphery having a recessed portion with a receptacle extending in a radial direction perpendicular to the axis. A control member is moveably received in the receptacle to control coupling of the drive column and an object to be driven. In any case, a spacing from an outer end of the control member to the axis in the radial direction is substantially not larger than a spacing from the outer periphery of the reinforcing section to the axis in the radial direction.

An assembly error prevention member includes a first plate portion that is attached to a first tab and a third plate portion that is inserted into a slit. The third plate portion has a blocking portion that inhibits a bolt from being tightened into a bolt hole and a driven portion that moves the blocking portion. The second plate portion has a first end portion connected to the first plate portion and a second end portion connected to the third plate portion. The second end portion is wider than the first end portion.
