A stabilizer for a recreational vehicle, comprising:

• a first support structure, a second support structure, and a locking mechanism, wherein
• the first support structure comprises an outer tube;
• the second support structure comprises:
• a casing, slidably sleeved to an outer side of the outer tube;
• at least three side support bars, a first end of each of the at least three side support bars being hinged with an outer wall of the casing respectively;
• and
• at least three connecting rods, one end of each of the at least three connecting rods being hinged with a second end of the outer tube, and another end of each of the at least three connecting rods being hinged with the side support bars;
• wherein the casing selectively moves in a first direction of a first end of the outer tube or in a second direction of the second end of the outer tube, so as to adjust a height of the stabilizer;
• and
• the locking mechanism comprises:
• a first limit member, fixedly provided on an outer wall of the outer tube in a longitudinal direction of the outer tube;
• a housing, fixedly connected to the outer wall of the casing;
• and
• a second limit member, confined to and movably connected to the housing;
• wherein the second limit member is selectively abutted against the first limit member, so as to lock a degree of freedom of the casing in the first direction;
• the first support structure further comprises an inner tube, the inner tube is sleeved within the outer tube and slidably connected to an inner wall of the outer tube, and the inner tube is extendable or retractable in the first direction of the outer tube under an action of a driver;
• the driver comprises a threaded rod and a slider, the threaded rod is rotationally fixedly connected to the outer tube;
• the slider is provided with a threaded hole, the slider is in threaded connection with the threaded rod and fixedly connected to the inner tube;
• the threaded rod has a first end facing the first direction and a second end facing the second direction, and the second end of the threaded rod is rotationally sleeved with a fixing block which is fixedly connected to the inner wall of the outer tube;
• the second end of the threaded rod is provided with a first gear, the fixing block is sandwiched between the slider and the first gear, rotation of the threaded rod is capable of driving the inner tube to move in its longitudinal direction.
