[0031] Wherein, a first spring 8 is sleeved outside the rack engaging member 7, and two ends of the first spring 8 respectively abut against one side of the rack engaging member 7 and one side of the inner wall of the first connecting groove 6, so as to apply pressure to the rack engaging member 7. When the moving claw 5 is moved, precise adjustment can be achieved through the interaction between the rack engaging member 7 and the tooth groove 9. Moreover, after adjustment, rebound is not likely to occur, and it has high operation convenience.

[0032] Wherein, two groups of second connecting grooves are symmetrically arranged on the bottom side of the guide rail seat 4, two connecting rods 11 are fixedly installed on the top side of the fixed base 2, the two connecting rods 11 are respectively located in the two groups of second connecting grooves, a second spring 12 is sleeved outside the connecting rod 11, and two ends of the second spring 12 respectively abut against one side of the inner wall of the second connecting groove and the top side of the fixed base 2, so as to drive the rotary engaging member 14, the connecting shaft 3 and the guide rail seat 4 to automatically bounce up after the rotary engaging member 14 leaves the limit seat 13, and enable the rotary engaging member 14 to pass through the through groove, so that the rack engaging member 7 on the guide rail seat 4 leaves the top block 10 to unlock the moving claw 5.

[0033] Wherein, the locking mechanism includes an upper shell 15, a lower shell 16 is fixedly installed on one side of the upper shell 15 through fasteners, a connecting hole is jointly arranged on the top sides of the upper shell 15 and the lower shell 16, a lock rod 17 is slidably connected inside the connecting hole, and a lock hole corresponding to the lock rod 17 is arranged on the rotary engaging member 14, so as to stably lock the rotary engaging member 14.

[0034] Wherein, a reduction motor 18 is fixedly installed inside the upper shell 15, a gear 19 is fixedly installed on the output end of the reduction motor 18, a rack 20 is slidably connected inside the lower shell 16, the rack 20 is meshed with the gear 19, and the bottom end of the lock rod 17 passes through the connecting hole and is fixedly connected with the top end of the rack 20, so as to drive the automatic movement of the lock rod 17.

[0035] Wherein, a connecting column is fixedly installed on the top end of the guide rail seat 4, the connecting column passes through the two moving claws 5 and is fixedly installed with a fixing plate 22 for fixing a magnetic charger through fasteners, so as to conveniently fix the magnetic charger required for charging the watch on the fixing plate 22.

[0036] Wherein, an electronic lock 23 is fixedly embedded on one side of the cylindrical bracket 1, a circuit board 21 is fixedly installed inside the upper shell 15, the circuit board 21 is respectively connected with the reduction motor 18 and the electronic lock 23 through multiple groups of wires, and the electronic lock 23 is adapted to an electronic key, so as to conveniently control the reduction motor 18.

[0037] Wherein, an inclined surface is provided at the bottom end of the cylindrical bracket 1, and a bottom cover 24 is fixedly installed inside the bottom end of the cylindrical bracket 1. Two groups of screws 25 perpendicular to the inclined surface are symmetrically and fixedly installed on the bottom side of the bottom cover 24. Butterfly nuts 26 are threadedly connected to the outer sides of the two groups of screws 25, which can stably fix the cylindrical bracket 1 on a display stand or a display rack.

[0038] The working principle of this embodiment: When it is necessary to fix the watch, the reduction motor 18 in the product is externally powered. First, the reduction motor 18 is started by an electronic key to drive the gear 19 to rotate. The gear 19 drives the rack 20 and the lock rod 17 to move, and the lock rod 17 leaves the lock hole. Then, the fixed base 2 is rotated to drive the guide rail seat 4, the connecting shaft 3 and the rotating clamping part 14 to rotate. When the rotating clamping part 14 passes through the through groove, the second spring 12 drives the guide rail seat 4, the connecting shaft 3 and the rotating clamping part 14 to move upward, so that one end of the rack clamping part 7 leaves the top block 10. The rotating clamping part 14 leaves the limit seat 13 and moves into the through groove. At this time, the moving claw 5 can squeeze the rack clamping part 7 to move into the first connecting groove 6, thereby adjusting the position of the moving claw 5. The watch is placed in a suitable position and the two moving claws 5 are moved to clamp the watch. The watch and the guide rail seat 4 are pressed to make the tooth groove 9 contact the rack clamping part 7 again, so that the rotating clamping part 14 leaves the through groove. Then, the fixed base 2 is rotated to drive the guide rail seat 4, the connecting shaft 3 and the rotating clamping part 14 to rotate. When the rotating clamping part 14 is in a suitable position, the reduction motor 18 is started to drive the rack 20 and the lock rod 17 to move, so that the lock rod 17 moves into the lock hole to lock the rotating clamping part 14, and the fixation of the watch is completed.

[0039] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for specific purposes.
