Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an internal mechanism of a secondary anti-theft lock which is a continuation of the patent application No. 9 2 1 3 6 1 1 7 and particularly refers to its shielding sheet The side edge is provided with an arc-shaped rack, and the bottom edge of the rotary block is provided with an arc-shaped rack ', which can correspond to the meshing and achieve a stable and reliable interlocking effect. [Previous technology] According to the current, the main switch of the traditional locomotive is equipped with a lock core, but because the key hole of the lock core is exposed, it is quite easy for dust and other impurities to enter, which affects the life of the lock core and the effect of unlocking. In particular, thieves can insert tools such as screwdrivers into the keyhole to damage the lock core to easily steal the locomotive, so its anti-theft effect is quite poor. For this reason, a structure that can hide the vacant holes is generated. As shown in the invention patent No. 434361, No. 477758 * 5 Tiger, and No. 550328 said Xuan patent, it is mainly set in the cylinder lock with a number of vertical arrangements The magnet is equipped with the same polarity magnet on the key. The principle of same-sex repulsion is used to achieve the effect of closing the mask and opening the keyhole. However, because the magnet is arranged in a vertical direction, and the related components are all set It is located at the side of the keyhole, so its volume is large and it takes up space, making the overall configuration difficult. At the same time, after the keyhole is opened, the shielding sheet is prone to create gaps and cause foreign matter such as dust to invade. It is not ideal, and it is difficult to achieve practicality. Therefore, in view of the main switch lock structure of the conventional locomotive, the present inventor has the above-mentioned shortcomings. Therefore, he devoted himself to research, and after many tests and improvements, he was able to create the first 9 2 1 3 61 1 7 5 Tiger patent applications. However, although this case has solved the lack of custom products, the side edge of the original shielding sheet is provided with a sliding groove [formerly known as the snap mechanism (3 3)] for the bottom edge of the original rotating block.
