摘要: A lifting strut having an adjusting sleeve with an externally threaded portion and an internally threaded portion. A connecting end with a threaded journal is screwed into the internally threaded portion, with a connecting end with a threaded sleeve being screwed on to the externally threaded portion. In addition, there is provided a movable holding sleeve having grooves and stops. The holding sleeve may be moved into any position relative to a rotary cross member of the adjusting sleeve provided with teeth for the purpose of changing the length of the lifting strut. Furthermore, the holding sleeve, with its grooves, may be moved across the teeth of the rotary cross member and across the teeth provided at the threaded sleeve in a corresponding position in order to arrest the change in length.
