Adjusting height of trailer towing fork - using spring-loaded deflectable clamp fixed around extendable rod

摘要

The device adjusts the height of a towing fork on a trailer having a connection between the towing fork and the trailer vehicle frame. It comprises a tube and a longitudinally displaceable rod, with a spring-loaded clamp (7) which engages the rod with a degree of play. One of the support surfaces (10) acting against a tension spring (12) has a measure of flexibility such that the force of the spring (12) causes the surface to move counter to the action of the clamp controlled by a spring (8), such that the clamp deflects. USE/ADVANTAGE - Trailer coupling which is easily adjusted and which remains secure in the new position.
