the middle lock core 26 and the upper lock core 25 can also be connected by small screws or welding or barium loose release, or a clamp spring 252 and a connecting block 254 are not arranged, but a proper method is used for leaving 0.4 mm of residual increase which is larger than the height of the clutch interval 27 of the middle lock core 26 and the lower lock core 24 after the middle lock core 26 and the upper lock core 25 are twisted and newly cracked, so that the residual increase is propped against the reinforced concave-convex card 5 to ensure that the concave-convex card is not separated and released, and the upper lock core is prevented from being pulled to be unlocked by strong magnetism, strong glue or other modes after cracking. According to the key 4 with depth, eccentric spiral groove key entrance hole 21 (figure 5) of different size, the key entrance hole 21 is eccentrically arranged on the lock core (1) (figure 6), the lock core 2 is eccentrically arranged on the round lock core base 1 (figure 7), a plurality of eccentric settings accumulated deviation enables to assemble marble 61 in a plurality of marble holes 6, use drilling-proof and other damage-resistant materials, the lock core base 1 is sheathed, the several aspects can be used simultaneously or partially, in the technical unlocking resistance and forced force unlocking resistance, only one marble 61 can normally stabilize the reinforced concave-convex card 5, the reinforced concave-convex card 5 can stabilize to prevent abnormal unlocking, when the key 4 is inserted into the key entrance hole 21 of the lock core 2, the marble 61 is ejected according to the set marble bit of each spiral strip 41, at this time, the key 4 is rotated, the lower lock cylinder 24 rotates firstly, the rotation time is the time when the connecting joint 23 slides down and separates from the reinforced concave-convex card 5 under the pulling of the spiral transmission spiral force, and after the lower sliding in place and the second half cut seam allowance 262 of the lower lock cylinder 24 are tightly meshed into a whole, the lower sliding in place and the reinforced concave-convex card rotate together with the unlocking transmission rod 3 arranged on the upper lock cylinder 25 to unlock. If the key 4 is not provided, a general tool of the spiral key inlet hole 21 is difficult to plug in, the eccentric spiral strip 41 is added, the center of the key inlet hole 21 is blocked, the key hole of the eccentric spiral strip is not provided with a lock cylinder convex stop 265, the number of marbles 61 is large, the number of long marbles 61 is large, the key 4 is also provided with a thin curved special-shaped spiral strip, the thin curved special-shaped spiral strip is smaller, the lock cylinder spiral groove is deeper, the spiral shielding body for shielding the marbles 61 is stronger, and the difficulty in technical opening is large. If strong unlocking is desired, because the lock core 2 is divided into sections, the unlocking transmission rod 3 for unlocking is arranged at the top of the neck of the upper lock core 25 through the unlocking transmission rod joint 31, the reinforced concave-convex card 5 is arranged at the joint of the neck rabbet of the upper lock core 25 and the lock core seat 1, the reinforced concave-convex card 5 is pushed up first regardless of skill or strong unlocking, although the strength of the reinforced concave-convex card 5 is high, the material quality of a strong unlocking tool is good, most of the marbles 61 are removed by using a soft and hard quick unlocking tool method, and the reinforced concave-convex card 5 is damaged without breaking to generate a horn mouth and slide down for unlocking, the invention adopts the connecting rail 254 to be matched with a cracking protection method of the upper lock core 25 to ensure that unlocking cannot be carried out under the conditions, thereby solving the problems, the strength of the reinforced concave-convex card 5 is high, the strength of the connecting rail 254 is low, and when the strength of the strong unlocking tool exceeds the strength of the connecting rail 254, the reinforced concave-convex card 5 is not damaged and the connecting rail 254 breaks first, the middle lock core 26 and the upper lock core 25 are separated by cracking, the cracked surface of the upper lock core 25 is flat, so that the clamp spring 252 arranged at the joint of the middle lock core 26 and the upper lock core 25 rapidly and elastically contracts to be about 0.5 mm in height or is movably connected, if the clamp spring is not cracked, about 0.5 mm of residual is left, because the difference between the height of the reinforced concave-convex card 5 and the separation distance 27 is only about 0.1 mm, the increased height of about 0.5 mm after the middle lock core 26 and the upper lock core 25 are cracked can support the reinforced concave-convex card 5 to be not separated, and the tension of the first spring 32 at the neck of the upper lock core 25 is stable, so that the reinforced concave-convex card 5 cannot be pulled down by other means even if the support of the marble 61 is not supported, after cracking, even if the marble 61 arranged on the connecting gear and the lock core 2 is broken by a strong cracking tool, the middle lock core 26 and the upper lock core 25 can only be pulled off by an idle rotation tool, the lock still can't be opened, and the technique of preventing not only is unblanked but also can prevent to open violently by force and unblank by force by this embodiment, and it is suitable for multiple use lock, can carry out the lock core to general lock and change the security performance who improves the lock.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
