Under the driving, the cutting surface 51 is separated from the lock seat 4 The corresponding position of the through hole 431 is such that the outer wall surface of the connecting seat 5 abuts the positioning steel ball 45 disposed in the through hole 431 of the lock core seat 4, and the positioning steel ball 45 is pushed outwardly, and a part of the positioning steel ball 45 is externally inserted. It is disposed in the positioning groove 26 of the body 2 (as shown in the fifth and sixth figures), so that the locking action can be completed, by positioning the embedded position of the steel ball 45, and the buckle of the insertion rod 7, The disc lock of the invention is firmly locked on the disc A of the locomotive, and the external body 2 of the invention has no pin hole arrangement, and the thief can not know the internal lock structure by the appearance, so the best can be achieved. Anti-theft function; when unbuttoning, the key (not shown) is inserted into the key socket 40 of the lock seat 4, so that the key penetrates into the lock core 41, and when the key 41 is rotated by the key, the lock 41 is The connecting rod 5 is rotated by the latch 53. When the connecting seat 5 rotates, the connecting seat 5 drives the coil spring 6 to be elastically twisted, and the cutting surface 51 of the connecting seat 5 corresponds to the through hole 431 of the lock core seat 4 again. The positioning steel ball 45 embedded in the positioning groove 26 of the body 2 is no longer resisted by the outer wall surface of the connecting seat 5, It can be pushed inward along the circular 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 to push the connecting seat 5 and the lock core seat 4 upward (as shown in the eighth figure), so that the upper part of the lock core seat 4 protrudes out of the body 2, and the insertion rod 7 is locked with the lock core. The seat 4 is moved up and disengaged from the insertion slot 21 of the body 2 and the perforation A1 of the disc A, and the body 2 can be removed from the disc A, so that the unlocking action can be completed, and the invention is very useful in use. Convenient, and the overall volume is small, less occupying the space.

In view of the above, the present invention has achieved the intended use and efficacy, and is more desirable and practical than the prior art, but the above embodiments are only specifically described for the preferred embodiment of the present invention.
