1. A sliding device comprising a first sliding part and a second sliding part, where the second sliding part is movably located in the first sliding part, so that the second sliding part can move in the first and second axial directions along the longitudinal axis of the first sliding part, a connecting device for limiting the displacement of the second sliding part relative to the first sliding part, where the connecting device has a first and second connecting configuration, where: - the first connecting the configuration limits the displacement in the first axial direction, allowing displacement in the opposite second axial direction, and the second connecting configuration limits the displacement in the second axial direction, allowing displacement in the opposite first axial direction, where the connecting device is adapted to selectively switch from the first connecting configuration to the second connecting configuration, and vice versa, when a force is applied, above a predetermined level, to the second sliding part in the axial direction , The displacement of which is limited to the first or second connecting konfiguratsii.2. The sliding device according to claim 1, where the application of force to the second sliding part is provided by pushing the second sliding part in the direction of the first sliding part. The sliding device according to claim 1, where the application of force to the second sliding part is provided by pulling the second sliding part in the direction from the first sliding part. The sliding device according to claims 1-3, where the predetermined level of force is in the range of 1-30 N, more specifically in the range of 3-20 N, more1. Раздвижное устройство, содержащее первую раздвижную часть и вторую раздвижную часть, где вторая раздвижная часть с возможностью перемещения расположена в первой раздвижной части, так что вторая раздвижная часть может перемещаться в первом и втором осевых направлениях вдоль продольной оси первой раздвижной
