Description

technical field [0001] The invention relates to an anti-theft device, in particular to an anti-theft lock which is fixed on the ground and realizes anti-theft through a chain, in particular to a chain-type anti-theft lock for vehicles. Background technique [0002] At present, vehicle anti-theft is a matter of great concern and headache for governments, citizens and public security at all levels. For this reason, various anti-theft locks emerge in an endless stream, but most of them are limited to the improvement of anti-pick functions. Theft, such anti-theft locks are powerless. Therefore, there is an urgent need for an anti-theft lock that not only has an anti-prying function, but also prevents the overall handling behavior from occurring. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to design a chain type vehicle anti-theft lock which is fixed on the ground and has good anti-pick and anti-shear functions, aiming at the problem that the exis...
