An automatic locking device for a snow anti-skid chain, comprising:
- a housing;
- the housing comprises a first spindle and a second spindle provided perpendicular to a bottom of the housing;
- an energy storage elastic member surrounding the first spindle;
- a rotation ratchet wheel, having an edge comprising limit-position teeth and positioning teeth;
- a release limit-position buckle, linked with the release button;
- when the release limit-position buckle is pressed downwardly, the release limit-position buckle drives the locking buckle to rotate around the second spindle under pressure of the head spring to engage the fixed tooth at the second end of the locking buckle with a corresponding limit-position tooth at the edge of the rotational ratchet wheel and push the first end of the locking buckle to reset the release button outwardly, thereby withdrawing the rotary buckle from being lammed and stopped in the corresponding positioning tooth along with the release button.
