the middle lock core 26 and the upper lock core 25 can be connected by small screws or welding or barium, or the snap spring 252 and the connecting rail 254 are not arranged, but the residual of the materials which are used in a proper method is at least left 0.4 mm after the new lock core is twisted and split, and the height of the clutch interval 27 which is larger than that of the middle lock core 26 and the lower lock core 24 is increased, so that the middle lock core 26 and the upper lock core 25 are propped against the reinforced concave-convex card 5 to ensure that the separation and the release of the lock are not carried out, and the upper lock core is pulled and moved to unlock by using strong magnetism, strong glue or other modes after the split is prevented. According to the key 4 provided with the key inlet holes 21 (shown in fig. 5) with eccentric spiral grooves with different depths and sizes, the key inlet holes 21 are eccentrically arranged on the lock cylinder 1 (shown in fig. 6), the lock cylinder 2 is eccentrically arranged on the round lock core seat 1 (shown in fig. 7), a plurality of eccentric arrangement accumulated deviations enable the assembling of the marble 61 in the plurality of marble holes 6, the manufacturing of anti-damage materials such as anti-drilling and the like, the lock cylinder seat 1 is sheathed, the aspects can be simultaneously used or partially used, the reinforcing concave-convex card 5 can be stably fixed only by one marble 61 in the process of technical unlocking and forced unlocking, and the abnormal unlocking can be prevented by reinforcing the concave-convex card 5, when the key 4 is inserted into the key inlet holes 21 of the lock cylinder 2, the marble 61 is jacked up according to the set marble position teeth of each spiral strip 41, at this time, the key 4 is rotated, the lower lock core 24 rotates first, the rotation time is the time when the coupling joint 23 slides off under the reinforced concave-convex card 5 under the pulling of the screw driving screw force, after sliding in place and tightly biting into a whole with the second half notch 262 of the lower lock core 24, the lower lock core rotates together with the unlocking transmission rod 3 installed on the upper lock core 25 to unlock, if the key 4 is not used, the general tool of the spiral key entrance hole 21 is difficult to plug in, the eccentric screw strip 41 is added, the center of the key entrance hole 21 is blocked, the key hole of the eccentric screw strip is not provided with the lock core convex block 265, the more and longer marbles 61 are arranged on the marble 61, the thin curved special-shaped screw strip is arranged on the key 4, the thinner the thin curved special-shaped screw strip is, the smaller the lock core screw groove is, the thinner and deeper the screw groove is, the stronger the spiral shielding body shielding the marble 61 is, the technical difficulty is great. If the lock is to be opened strongly, because the lock cylinder 2 is divided into sections, the unlocking transmission rod 3 is installed at the top of the neck of the upper lock cylinder 25 by the unlocking transmission rod joint 31, the joint of the neck seam allowance of the upper lock cylinder 25 and the lock cylinder seat 1 is provided with the reinforced concave-convex card 5, no matter whether the reinforced concave-convex card 5 is opened or opened strongly, the reinforced concave-convex card 5 is acted on by force first, the strength of the reinforced concave-convex card 5 is high, but the material of the forced opening tool is good, most of the marble 61 is removed by a method of a soft and hard quick opening tool first, the horn mouth is produced by damage caused by no breakage of most of the forced opening reinforced concave-convex card 5, the unlocking can not be ensured under the condition by adopting the splitting protection method of the upper lock cylinder 25, thereby solving the problems, the reinforced concave-convex card 5 is high in strength and the designed with the connecting gear 254 is low, when the forced opening tool strength exceeds the connecting gear 254 strength, the reinforced concave-convex card 5 is not broken first and the connecting gear 254 is broken, the split surface of the split upper lock cylinder 25 is flat, so that the clamp spring 252 arranged at the joint of the middle lock cylinder 26 and the upper lock cylinder 25 rapidly and elastically contracts to block up by about 0.5 mm, or is in movable split connection, if the clamp spring is not provided for split, about 0.5 mm is left, because the difference between the height of the reinforced concave-convex card 5 and the spacing of the clutch interval 27 is very small, about 0.1 mm, the block height of the middle lock cylinder 26 and the upper lock cylinder 25, which is increased by about 0.5 mm after split, can prop against the reinforced concave-convex card 5 to separate, and the tension of the first spring 32 at the neck of the upper lock cylinder 25 is stable, so that even if the top supporting reinforced concave-convex card 5 without the marble 61 is not pulled down by other means after split, the marble 61 arranged on the connecting block 254 and the lock cylinder 2 can be broken by a strong opening tool, the middle lock core 26 and the upper lock core 25 can only idle, and the lock can not be opened, so that the embodiment not only can prevent technical unlocking, but also can prevent forced unlocking, is suitable for various locks for occasions, and can replace the lock core of a common lock to improve the safety performance of the lock.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
