[0023] In this embodiment, the movable inner tube body 3 arranged in the first anti-corrosion and wear-resistant tube body 1 is controlled by the position adjustment drive 6 to move forward or backward in a straight line. Since the inner tube body 3 is connected and matched with the second anti-corrosion and wear-resistant tube body 2, and the telescopic groove 5 provides an avoidance interval for the movement of the second anti-corrosion and wear-resistant tube body 2, a pair of sealing components 4 are used to give the inner tube body 3 and the first anti-corrosion and wear-resistant tube body 1 sealing properties for straight-line movement.
