Generally, the first housing 2 is intended to be fixed to a frame element, such as a window frame, a door frame or the like, while the second housing 3 is intended to be fixed to a wing, such as a door leaf or a window sash, which is arranged in a sliding manner so as to be openable on the frame element. The fixing manner of the first and second housings 2, 3 and the corresponding frame or wing may be various, for example, by gluing (such as 3M glue), screw fixing or clamping, but other known connection manners may be used, and the fixing manner is not limited in principle, and may be any manner as long as the first or second housings 2, 3 can be fixed to the frame or wing.

In order to allow a slightly greater opening angle of the sliding wings or, in other words, to allow a shorter overall length of the telescopic link assembly 1 in the locked condition, it is preferable to provide said housing cavities on each of the two main bars 13. In detail, the two main bars 13 are provided with said housing cavities at their ends close to each other. In other embodiments, the accommodating cavity may be provided on only one main rod 13, and at this time, the other main rod 13 is fixedly connected with the connecting rod 12 in a non-slidable manner, and the connection manner of the other main rod 13 and the connecting rod 12 includes, but is not limited to, screw connection, snap connection, adhesive connection, threaded connection, and even integral processing.
