The groove can only be formed by a straight groove with the same width under the surface, or the upper width and the width are formed from the surface. (4) is the upper and lower narrow eight-ditch, so that the lock hole of the corresponding lock can only form a line shape and no and the sacrifice can easily cause the unscrupulous person to use the flat-shaped unlocking lock to force the rotation in the lock hole. The unlocking has caused the people even more serious threats and harms to the king of the people. So, the inventor is inferior to the existing keying embryo in the molding. 1 1344400 Research:::=: It is very easy to use the unlocking tool to forcibly unlock the lock, which is the key embryo of the new groove formed by the announcement.
