Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Please refer to Figure 1 - Figure 6 A kind of anti-theft label strong force release, including sleeve shell 1, the top of sleeve shell 1 is connected with sealing cover 2 by screwing, the top of sealing cover 2 is rotatably connected with rotating column 3, the inner wall of sleeve shell 1 is slidably connected with installation shell 4, the inner wall of installation shell 4 is movably connected with magnet 5, the bottom of sealing cover 2 is fixedly installed with fixed sleeve 8, the bottom of rotating column 3 is fixedly installed with threaded sleeve 9, the inner wall of installation shell 4 is fixedly installed with fixed slot 10, the inner wall of installation shell 4 movably sleeve joint has installation cover 11, the top of installation cover 11 is fixedly installed with threaded rod 6 and sliding rod 7 respectively, the inner wall of installation cover 11 is slidably connected with lock pin 12, the top of lock pin 12 is fixedly installed with pull block 13, the inner wall of installation cover 11 is fixedly installed with limiting rod 14, the inner wall of installation cover 11 is equipped with spring 15, in the above structure, the top of installation cover 11 is equipped with notch, pull block 13 is connected with lock pin 12 by the notch, so that pull block 13 is pulled from the top of installation cover 11, and then lock pin 12 is moved by pull block 13.

[0023] In a preferred embodiment, threaded rod 6 is located in the inner wall of threaded sleeve 9, and the threads on the outer wall of threaded rod 6 are adapted to the threads in the inner wall of threaded sleeve 9, threaded rod 6 and threaded sleeve 9 are connected by screwing, in the above structure, threaded sleeve 9 is rotated, and then the threads in the inner wall of threaded sleeve 9 are rotated, the inner wall of threaded sleeve 9 is connected with threaded rod 6 by screwing, and then threaded rod 6 is moved upward, so that threaded rod 6 pulls the installation cover 11 at the bottom to move upward.

[0024] In a preferred embodiment, the number of fixed sleeves 8 and sliding rods 7 is two, and the two fixed sleeves 8 and sliding rods 7 are symmetrically arranged on both sides of the threaded rod 6 with the axis of the threaded rod 6 as the center, and the top of the two sliding rods 7 is on the inner wall of the two fixed sleeves 8. In the above structure, when the mounting cover 11 is moved up and down, the mounting cover 11 will drive the sliding rod 7 at the top of the mounting cover 11 to move up and down. At this time, due to the up and down movement of the sliding rod 7, the sliding rod 7 moves up and down on the inner wall of the fixed sleeve 8, and then the fixed sleeve 8 limits the movement of the sliding rod 7, and then the sliding rod 7 limits the mounting cover 11, so that the mounting cover 11 will not rotate due to the rotating force of the threaded sleeve 9.

[0025] In a preferred embodiment, the outer wall of the threaded sleeve 9 is provided with an extension ring, and the extension ring is located at the bottom of the sealing cover 2. The extension ring of the outer wall of the threaded sleeve 9 is attached to the bottom of the sealing cover 2. In the above structure, the extension ring of the outer wall of the threaded sleeve 9 makes the threaded sleeve 9 unable to move upward at the bottom of the sealing cover 2, and the threaded sleeve 9 is fixed by rotating the column 3 so that the threaded sleeve 9 cannot move downward.

[0026] In a preferred embodiment, the height of the fixed groove 10 is the same as the height of the locking pin 12, and the shape of the locking pin 12 is matched with the shape of the fixed groove 10. In the above structure, the locking pin 12 is inserted into the inner wall of the fixed groove 10, and then the position of the locking pin 12 is fixed by the fixed groove 10, and then the position of the mounting cover 11 is fixed.

[0027] In a preferred embodiment, the number of limiting rods 14 is two, and the two limiting rods 14 penetrate the two sides of the locking pin 12. The two limiting rods 14 and the locking pin 12 are in sliding connection. In the above structure, the two limiting rods 14 penetrate the two sides of the locking pin 12, so that the locking pin 12 can slide on the outer wall of the two limiting rods 14, and then the locking pin 12 can only slide on the outer wall of the two limiting rods 14 during movement, so that the locking pin 12 will not tilt during movement.

[0028] The working principle is that when the device is used, the bottom of the sleeve shell 1 is close to the lock buckle, so that the internal structure of the lock buckle is opened, and the lock buckle is opened. When the magnetic force needs to be adjusted, the rotating column 3 is rotated, so that the rotating column 3 drives the threaded sleeve 9 to rotate. The threaded sleeve 9 drives the threads on the inner wall to rotate. The inner wall of the threaded sleeve 9 is screwed with the threaded rod 6, so that the threaded rod 6 moves up and down on the inner wall of the threaded sleeve 9, so that the threaded rod 6 pulls the bottom mounting cover 11 to move up and down. The mounting cover 11 drives the mounting shell 4 and the magnet 5 to move up and down, so that the distance between the magnet 5 and the bottom of the sleeve shell 1 is adjusted, so that the magnetic force of the magnet 5 to the bottom of the sleeve shell 1 is adjusted. When the magnet 5 needs to be replaced, the sealing cover 2 is rotated, so that the sealing cover 2 is taken off from the top of the sleeve shell 1. At this time, the sealing cover 2 is pulled upwards, so that the sealing cover 2 drives the rotating column 3 and the threaded sleeve 9 to move upwards. The threaded sleeve 9 drives the threaded rod 6 to move upwards. The threaded rod 6 drives the mounting shell 4, the magnet 5 and the mounting cover 11 to move upwards. At this time, the pull block 13 is pulled, so that the pull block 13 drives the lock pin 12 to move towards the inner wall of the mounting cover 11, so that the lock pin 12 is separated from the fixed groove 10 in the mounting shell 4. At this time, the fixed relationship between the mounting cover 11 and the mounting shell 4 disappears. After the magnet 5 is replaced, the structure is reset.

[0029] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
