The present invention relates to a pressure-applying telescopic spacer, which is formed by two attached tubes (1 and 2) telescopically coupled to one another, with sheet metal rings (4) pushed by a spring (5) for establishing a wedging and driving of said sheet metal rings (4) on the inner tube (2) and blocking the axial movement of the latter with respect to the outer tube (1), this assembly of sheet metal rings (4) and push spring (5) being located in a head (6) belonging to a sleeve (7) with anchoring means (8) for the fixing thereof on the outer tube (1), said body determined by the sleeve (7) and the head or expansion (6) forming a handle for manually handling the spacer. Support plates (9) connected with movable means for adjusting the spacing length of the spacer itself to the desired measurement are included at the ends. |
