Whereby, a lock of the present invention can be assembled on a car body in practice as the following steps as
Wherein, the most important is that the grip seat 35 must be extended accurately and without any error to the upper side of the stereo lock 20 while executing the aforementioned Step 4, the disk pressing bolt 36 can only be moved forward to project into the through hole 34 via the aforementioned insertion openings 261 and 271, and finally prop against the positioning notch seat 262 of the rotating stick 26 after the disk pressing grip 36 is inserted in the through hole 34. Moreover, the lock head is pressed down to allow the locking bolt thereof to be projected out to penetrate into and couple to the front hole sheet of the disk pressing bolt 36 to lock and limit the lock head 26.
Whereby, a car lock according to the present invention can effectively prevent a thief from detaching stereo components, operating a steering wheel and hand brake lever to attain to the practical object of effectively preventing a car from being stolen because the whole effective collocation combination may be adopted on every kind of car and provides multiple protections such as steering wheel lock, electronic burglar alarm, stereo lock and hand brake alarm.
Furthermore, a user only needs to undo the locks 21, 31, 51 and etc. one by one while wanting to detach a car lock according to the present invention, and he may then unload the first combination connecting mechanism 30, the second combination connecting mechanism 40, the steering lock 10, the stereo lock 20, the hand brake lock 50 and etc. one by one; the detaching operation is not difficult; it is only a reverse operation of the aforementioned assembly steps, the details thereof is omitted here.
However, it is necessary to state here that because the disk pressing grip 30 of the present invention can only be moved forward in a single direction and is unable to be moved backward after being mounted in, the locking insertion stick 185 must be pulled out while being detached, the grasping compressing stick 31 is rotated, and a design of the relatively rotatable rotating stick is then operated in coordination to allow the front hole sheet 31 of the disk pressing grip 30 to be withdrawn automatically after being rotated with an angle; the stereo lock 30 can be taken down naturally and the disk pressing grip 36 may also be extended forward again to insert into the whole stereo lock 20 and then take it out. Thereafter, only if a hollow inner tube of the grasping compressing stick 31 is pushed into the connecting tube 18, it will finally prop against the L-typed elastic plate 177 to allow a long side thereof to be inserted into the base gap 178 to poke the tennon 175 away to cause the positioning bolt 162 to be released, and the steering wheel can then be unloaded.
