Inside the movable slot 30 of the base 3, make the other end 81 of the chain 8 align with the through hole 22 of the lock body 2 and the position of the insertion slot 330 of the swivel base 3 (as shown in Figure 5), and then protrude outward on the lock The lock seat portion 50 of the insertion rod 5 above the main body 2 is pressed into the lock body 2, the insertion rod 5 moves down, and the compression spring 4 is pressed and held, so that the compression spring 4 is in an elastically compressed state, and is inserted through the lock body 2. The lower end of the insertion part 51 of the insertion rod 5 in the through hole 22 of the lock body 2 is inserted into the other end 81 of the chain 8 and inserted into the insertion slot 330 of the fixed seat 33 in the swivel base 3 . The lock steel ball 512 on the insertion rod 5 is aligned with the lock ring groove 331 of the fixed seat 33 in the swivel base 3, and the lock cylinder 6 is rotated by the key 9, and the lock cylinder 6 drives the lock rod 63 to rotate, and the lock rod rotates. The arc groove 631 of 63 is rotated away from the steel ball hole 511 of the insertion rod 5, and the rod wall of the lock rod 63 pushes the lock steel ball 512 outward, so that a part of the lock steel ball 512 protrudes outward from the insertion rod. The rod 5 is embedded in the lock ring groove 331 of the fixing seat 33 (as shown in FIG. 6 ). After locking, the key 9 is removed from the lock core 6, and then the shutter 73 of the dust cover 7 is covered. On the through hole 70, the locking action can be completed in this way; the present invention directly fixes one end 80 of the chain 8 in the fixing slot 23 of the lock body 2 by means of the insertion rod 5, which can reduce the lateral volume of the lock body 2, In addition, by virtue of the setting position of the locking steel ball 512 and the locking lever 5, the other end 81 of the chain 8 can be securely locked in the movable slot 30 of the swivel base 3 (as shown in FIG. 6 and FIG. 7 ). shown), has excellent anti-theft effect, and the design of the swivel base 3 of the present invention can be rotated at any angle at the bottom of the lock body 2, and the user can adjust the movement on the swivel base 3 according to the space of the locking object. The relative locking angle of the slot 30 and the fixing slot 23 of the lock body 2 (as shown in FIG. 8 ) makes it easier to use when locking objects without being unable to complete the locking action due to space constraints. , and a dust cover 7 is provided on the lock body 2, which can prevent foreign objects and dust from entering the key hole 61 of the lock core 6 to affect the operation of the internal structure, and has an excellent dustproof effect; , it is only necessary to open the shutter 73 of the dust cover 7 from the through hole 70, and then insert the key 9 into the key hole 61 of the lock core 6, so that the key 9 drives the lock core 6 to rotate, and the lock core 6 is connected in parallel. The movable lock lever 63 rotates, and the arc groove 631 of the lock lever 63 is aligned with the steel ball hole 511 of the insertion lever 5 again. The lock steel ball 512 embedded in the lock ring groove 331 of the fixed seat 33 is not When pressed against the outer wall surface of the locking rod 63 , it can move inwardly into the steel ball hole 511 of the insertion rod 5 and the arc groove 631 of the locking rod 6 , and is no longer embedded in the locking ring groove 331 of the fixing seat 33 . and the compression spring 4, which is also arranged in the accommodating groove 20 of the lock body 2, elastically returns to push the insertion lever 5 upward (as shown in FIG. 5), so that the lock seat portion The upper part of the 50 protrudes outward from the lock body 2, and the insertion rod 5 is pushed up by the compression spring 4 and disengaged from the insertion slot 330 of the swivel base 3 and the fixed base 33 and the other end 81 of the chain 8. The chain 8 The other end 81 of the lock can be taken out from the movable slot 30 of the swivel base 3, so that the unlocking action can be completed. Any item lock position, with excellent anti-theft effect.
