The present invention comprises an angularly adjustable coupler (50).

Interface vertical height and angular adjustment mechanisms are also disclosed.

The instrument can also include an angular adjustment mechanism (36).

The roller further includes an angular adjusting means (46) for angularly adjusting the handle.

An angle-adjusting device for wall rack includes a turning connecting rod and a tilt angle-adjusting device.

The first and second ends (60, 90) are in an angularly adjustable mating engagement.

An adjustable keyboard holder (20) that is infinitely adjustable both angularly and vertically.

An angular-adjustment lever is pivotally mounted to the turntable.

The platform is mounted on a pedestal in an angularly adjusted position.

The positioning device (13) has a height adjustment system (21) and/or angle adjustment system (22) and/or lateral adjustment system (46).

In addition, another bush (35) is provided on one of the other bushes (14) while being laterally joined thereto via a flange (33) and is provided in the form of an angle adjusting device with the provision of a locking screw (34) and securing nuts (38).

The invention relates to a device for angular adjustment of a direction-indicating object of an antenna device, whereby the invention causes the direction-indicating object to perform a mechanical movement without rotating.

Hydraulic devices are provided for angular adjustment of the tractor-coupling frame (6).

One alternative is a direct drive system having angularly adjustable levers.

The angular adjustment device thus formed can be advantageously combined with a complementary device for axial adjustment of the radial position of the assembled elements.
