The invention provides a self-tightening device of an antiskid chain and the antiskid chain. The self-tightening device of the antiskid chain comprises a base, a reel connected to the base, and a control part. First ratchets and second ratchets are arranged on the reel, wherein the first ratchets and the second ratchets are arranged in the axial direction and are opposite in the circumferential direction of the reel. The control part comprises a first pawl and a second pawl. The first pawl can move to be meshed with the first ratchets or not meshed with the first ratchets. The second pawl can move to be meshed with the second ratchets or not meshed with the second ratchets. When the first pawl is meshed with the first ratchets, the second pawl is not meshed with the second ratchets. When the first pawl is not meshed with the first ratchets, the second pawl is meshed with the second ratchets. The reel can rotate only in one direction under any state, and therefore it is ensured that when the reel rotates in the guy rope pull-out direction, a guy rope can be pulled out but can not retract and when the reel rotates in the retracting direction of the guy rope, the guy rope can retract but can not be pulled out. The guy rope is prevented from being automatically rewound on the reel when a user suddenly loses control over the guy rope during installation of the antiskid chain.
