The invention discloses an adjuster and aims at providing a track gauge adjuster. According to the track gauge adjuster, relatively long tracks can be stably moved in one time, and an ideal storage function can be realized. According to the key point of the technical scheme, a main hydraulic cylinder is connected with an external hydraulic power supply, a main hydraulic chamber is formed in the main hydraulic cylinder, a main plunger rod is hermetically and slidably connected in the main hydraulic chamber, a slipping end and an output end are arranged on the main plunger rod, and a secondary hydraulic chamber is formed in the output end and comprises a left secondary chamber and a right secondary chamber; a left plunger rod is hermetically and slidably connected in the left secondary chamber, a left plunger chamber is formed in the left plunger rod, and a left ejector rod is hermetically and slidably connected in the left plunger chamber; a left auxiliary chamber is formed in the left plunger chamber, and a left auxiliary rod is heremtically and slidably connected in the left auxiliary chamber; a right plunger rod is hermetically and slidably connected in the right secondary chamber, a right plunger chamber is formed in the right plunger rod, and a right ejector rod is hermetically and slidably connected in the right plunger chamber; the left auxiliary chamber is formed in the right secondary chamber, and a right auxiliary rod is hermetically and slidably connected in the right auxiliary chamber; the slipping directions of the left ejector rod, the left auxiliary rod, the right ejector rod and the right auxiliary rod are accordant with the slipping direction of the main plunger rod.
