The invention discloses a carrier. According to the carrier, mutually-spaced carrying vehicle frames can be adjusted through synchronous, asynchronous, codirectional or reverse translational movement,and the distance between the two carrying vehicle frames is automatically adjusted to be matched with to-be-carried vehicles with different axle bases. The carrier is simple in structure, intelligentand easy to manufacture and mount, through an unpowered and passive telescopic connector provided with no kinetic energy and only stretching out and drawing back passively, the design structure is simplified further, the manufacturing cost and the mounting cost are lowered, the maintenance cost is low, and the service life is long; through linkage among a holding clamp driving hydraulic cylinder,a holding clamp clamping plate, a holding clamp rotary shaft and a holding clamp arm, the holding clamp rotary shaft further plays a role in lever supporting point to easily pull the holding clamp clamping plate to fix a holding lifting belt to carry wheels of the vehicles; and the structure is simple, the property is excellent, the integrity is stable, and the vehicle storing and picking up efficiency is high.
