The specific embodiment

A kind of multifunction anti-theft lock as shown in Figure 1, include lock body 1 and two fork locking bar 2, also include protective cover, this protective cover is made up of vest 4 and protective stent 5, this vest 4 surrounds lock body 1 and adopts bolt to be connected with lock body 1, and over against locating all to have through hole, protective stent 5 is a frame type at keyhole 11 for vest 4 and protective stent 5, one side is fixedlyed connected with vest 4, and gapped between through hole and the keyhole 11.In addition, two fork locking bars 2 are fixedly connected with anti-shear-steel plate 21 on the part of exposing lock body 1, also have the lock core tongue 3 of this multifunction anti-theft lock to be made as flat column.

Another kind of structure theftproof lock shown in Figure 2 directly is fixedly connected on protective stent 5 on the vest 4 by screw rod, and keyhole 11 has certain distance with vest 4 simultaneously.

The lock body 1 of this theftproof lock is provided with vest, strengthens the intensity of lock body, prevents destroyed; And protective stent 5 has hindered key insertion keyhole, though increased the difficulty of unblanking, holds the joyriding of master key for those, and is extremely difficult especially.

The part of two fork locking bars 2 being exposed lock body 1 increases the anti-shear-steel plate 21 of one deck, avoids joyriding that locking bar 2 is cut off; Because lock core tongue 3 is made as flat column, even locking bar 2 is cut off, locking bar 2 still can not be pulled out lock body 1 easily, in addition, flat column lock core tongue 3 has avoided adopting thin slice to insert the situation generation that lockhole can not opened common tongue simultaneously.

For fear of joyriding car is born away, can be with locking bar 2 lengthening designs; In addition, also the two ends of two fork locking bars 2 can be made as car repair tool: awl or screwdriver etc.
