Through long-term base application research, compare by a large amount of tests and scheme, propose the utility model and solve the technical scheme that its technical problem adopts, it comprises lock core, key among tapered end and the insertion tapered end, keyhole that connects before and after this lock core is provided with and the pellet shot from a slingshot hole that vertically is provided with and communicates with keyhole, described pellet shot from a slingshot is provided with extraordinary pellet shot from a slingshot and marble spring in the hole, the keyhole both sides of lock core front end is provided with and becomes the hole loose slot, is equipped with respectively in the two change hole loose slots to become the hole spring and become the hole movable part.
The keyhole both sides of described lock core is provided with two row's pellet shot from a slingshot holes, and the extraordinary pellet shot from a slingshot in the pellet shot from a slingshot hole is provided with the contact head that is complementary with the surfaces of keys profile of tooth.
The periphery of described lock core is provided with the horizontal groove that communicates with two row's pellet shot from a slingshot holes, be provided with latching member in the horizontal groove, between latching member and lock core, be provided with case spring, on the extraordinary pellet shot from a slingshot at the contact head back side, be provided with notch, latching member matches with notch on the extraordinary pellet shot from a slingshot, and tapered end is provided with the locking groove that matches with latching member.
The tapered distal end of described change hole movable part matches with locking groove.
After adopting said structure, with the mechanical type ball lock head of prior art following advantage and effect are arranged relatively: the one, keyhole adopts and becomes the hole technology, the anti-technical opening means of this tapered end have further been strengthened, because the pirate of the open instrument of technical opening occupies certain space, after the pirate of the open instrument inserts keyhole, the extruding of pirate of the open instrument becomes the hole movable part, change hole movable part is outwards moved, the tapered distal end that becomes the hole movable part is retracted in the locking groove, make tapered end increase blocking mechanism newly one on the contrary, therefore this structure can resist and retrain the pirate of the open instrument effectively and insert operation in the keyhole, has played the effect of shut the gate.The 2nd, extraordinary pellet shot from a slingshot is the moving shape of upstream and downstream and is arranged in the pellet shot from a slingshot hole, form closedown structure jointly by latching member, case spring and many extraordinary pellets shot from a slingshot, single extraordinary pellet shot from a slingshot does not independently constitute a locking junior unit, " narrow mouthful " that this technology can not produce theft to make pellet shot from a slingshot frictional force to increase, whether imperceptible this pellet shot from a slingshot was dialled and is opened success when theft was handled, in case and the pirate of the open instrument is removed by behind the pellet shot from a slingshot of dialling, this pellet shot from a slingshot resets under the pressure of marble spring immediately, therefore can guarantee that whole closedown structure is in blocking all the time.Thereby overcome every group of pellet shot from a slingshot of existing tapered end is a junior unit closedown structure, the fault of construction of easy crack.The 3rd, new tapered end adopts double closedown structure, increases the permutation and combination of tapered end pellet shot from a slingshot, makes the tapered end size of key higher, and opening difficulty is bigger, and mutual opening rate is lower.
