The second gear 45 and the tooth 15 are in the meshing state, and the first rotating shaft 24 is rotated by a tool to drive the first lock disc 23 and the second lock disc 25 to rotate synchronously. At this time, the first folding rod 22 drives the first lock rod 20 to move upward, and the second folding rod 28 drives the second lock rod 29 to move downward. The meshing of the tooth 15 and the second gear 45 drives the second gear 45, the tooth belt 43 and the first gear 42 to rotate, and the meshing of the first gear 42 and the rack 40 drives the racks 40 on both sides to be inserted into the corresponding clamping grooves 21. At this time, the two racks 40 stably press and fix the lock body mounting plate 17 to complete the fixed installation of the lock body mounting plate 17. When the first lock rod 20 continues to move upward, the tooth 15 and the second gear 45 are no longer meshed, that is, the rack 40 no longer moves, so it does not affect the subsequent locking operation. When unlocking, the first lock rod 20 moves downward, and when the tooth 15 and the second gear 45 are about to mesh, the auxiliary baffle 51 limits the first limiting slide plate 20 from moving downward any more, so as to prevent the rack 40 from being separated from the clamping groove 21 and causing the lock body mounting plate 17 to move. If it is necessary to disassemble the lock body mounting plate 17, the auxiliary baffle 51 is removed, the first rotating shaft 24 is continuously rotated, the first lock rod 20 continues to move downward, the tooth 15 and the second gear 45 are meshed, the second gear 45, the tooth belt 43 and the first gear 42 are driven to rotate, the meshing of the first gear 42 and the rack 40 drives the racks 40 on both sides to be separated from the clamping grooves 21, and the disassembly of the lock body mounting plate 17 is completed.
