ABSTRACT:
A lock-set for an automobile consists of a padlock body, a fixing rod and a holder. The padlock body includes a turnable cramp, a cylinder linking with a pushing bar and engaging with the cramp. One end of the pushing bar comprises an elastic element engaging with a switch within the fixing rod. The switch connects to an alarm circuit board in the holder. When the padlock body is secured on a steering wheel by the cramp, the elastic element of the pushing bar urging the switch inwardly thus activates the alarm system.
