Description

technical field [0001] The invention relates to hardware locks, in particular to anti-theft locks for automobiles. Background technique [0002] At present, in order to prevent the car from being stolen, locks connected in series by angle locks, connecting rods or steel ropes and straight locks are often used as anti-theft locks. But connecting rod or steel rope are shear-resistant, cut-resistant ability is relatively poor, under the action of roller type cutter, promptly breaks in a few minutes, so above-mentioned anti-theft lockset that is used for locking steering wheel has poor anti-theft performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-theft lock with simple structure, low cost, strong shear resistance and shear resistance, which can be applied to various types of automobiles such as cars and large trucks. [0004] In order to solve the above technical problems, the vehicle anti-theft lo...
