An auxiliary rod (5) is housed in a fixed tube (1) in a sliding and rotative manner, and partially surrounds the central rod. The central rod is housed in the auxiliary rod in a sliding manner. A pretensioning spring (6) is arranged in a hollow space formed in the cylindrical head to apply pretensioning force on the auxiliary rod.
