By positioning the positioning setting of the steel ball 45 and the buckle of the rod 7, the The disc brake of the present invention is securely locked on the disc brake pad A of the locomotive. The body 2 of the present invention has no pin holes on the outside. The thief cannot know the internal lock structure from the appearance, so it can achieve the best. Anti-theft effect; when unlocking, insert a key (not shown) into the key socket 40 of the lock center seat 4 to make the key penetrate into the lock center 41. When the key drives the lock center 41 to rotate, the lock center 41 and The connecting seat 5 is rotated by the pin 53. When the connecting seat 5 rotates, the connecting seat 5 drives the coil spring 6 to be elastically twisted, and the cut surface 51 of the connecting seat 5 corresponds to the perforation 431 of the lock seat 4 again. The positioning steel balls 45 embedded in the positioning grooves 26 of the main body 2 are no longer resisted by the outer wall surface of the connection seat 5, It can be pushed inwardly along the arc surface 260 of the positioning groove 26 to the cutting surface 51 of the connecting seat 5, and is no longer embedded in the positioning groove 26 of the body 2, and is simultaneously compressed in the chamber 22 of the body 2. The spring 3 is elastically restored and pushes the connection seat 5 and the lock center seat 4 upward (as shown in the eighth figure), so that the upper part of the lock center seat 4 protrudes beyond the main body 2, and the insertion rod 7 thereof follows the lock center The seat 4 moves upwards and leaves the insertion slot 21 of the body 2 and the perforation A1 of the disc brake A. The body 2 can be removed from the disc brake A. In this way, the unlocking action can be completed. The invention is very useful in use Convenient, and the overall volume is small, and it does not take up much space.

In summary, the present invention has indeed achieved the intended purpose and effect of use, and is more ideal and practical than the conventional one. However, the above embodiments are only specific descriptions of the preferred embodiments of the present invention.
