[0022] Specifically, the top side of the fixed frame 2 is fixedly connected to the chassis body 3, the top side of the chassis body 3 is provided with a long groove, a back plate 10 is inserted in the long groove, a plug block 11 is fixedly installed on one side of the back plate 10, and the plug block 11 is arranged in a U shape, a fixed block 12 is fixedly installed on one side of the fixed frame 2, a slot is provided on the fixed block 12, the slot is adapted to the plug block 11, an induction coil 17 is arranged on the bottom inner wall of the slot, a magnet 16 is fixedly installed on the other end of the plug block 11, the magnet 16 faces the induction coil 17, a square groove and an installation groove are respectively provided on one side inner wall of the long groove and one side of the plug block 11, a clamping component is arranged in the installation groove, a lock hole 18 is provided on one side of the fixed block 12, a placement groove is provided on the bottom inner wall of the lock hole 18, a power-off component is arranged in the placement groove, and the power-off component The component includes a second spring 19 fixedly installed on the inner wall of the bottom side of the placement groove, the other end of the second spring 19 is fixedly connected to the extrusion block 20, and the bottom side of the extrusion block 20 is fixedly installed with an extrusion rod 21. A circular hole is opened on the inner wall of the bottom side of the placement groove, and the circular hole is adapted to the extrusion rod 21. The other end of the extrusion rod 21 passes through the circular hole opened on the inner wall of the bottom side of the placement groove. The extrusion rod 21 is located between the second springs 19, and the fixed block 12 is opened with a placement cavity. The inner wall of the bottom side of the placement cavity is respectively fixedly installed with a controller 23 and a power-off switch 22. The top side of the power-off switch 22 is in contact with the other end of the extrusion rod 21. The power-off switch 22 is electrically connected to the controller 23. A push plate 25 is arranged in the square groove, and the push plate 25 is located on one side of the card block 15. A magnetic The alarm 24, the magnetic alarm 24, the induction coil 17 and the controller 23 are electrically connected. When the correct key is inserted into the lock hole 18, the key will contact the squeezing block 20, and then the squeezing block 20 will move downward to drive the other end of the squeezing rod 21 to move toward the power-off switch 22. When the squeezing rod 21 presses the power-off switch 22, the power between the power-off switch 22 and the controller 23 will be cut off. When the controller 23 is powered off, the magnetic alarm 24 and the induction coil 17 will also be powered off, thereby preventing the magnetic alarm 24 from sounding an alarm when personnel are replacing electronic parts in the chassis body 3. When the correct key is pulled out, the squeezing block 20 can be driven to move upward by resetting the second spring 19, and then the squeezing rod 21 can be away from the power-off switch. The power switch 22 is turned on, and the controller 23 is then powered on again. The induction coil 17 and the magnetic alarm 24 can operate normally again. When the thief uses the unlocking tool to unlock the door, the unlocking tool cannot squeeze the squeezing block 20. When the squeezing block 20 is not squeezed, the squeezing rod 21 will not move toward the power-off switch 22, so that the controller 23 is in a normal operating state. Therefore, when the back plate 10 is pulled up, the distance between the magnet 16 and the induction coil 17 becomes farther, thereby changing the magnetic field. This change will cause the current in the induction coil 17 to change. When the current in the induction coil 17 changes, the alarm system will be triggered, and the magnetic alarm 24 arranged on the top side of the chassis body 3 will sound an alarm.It can serve as a warning to thieves and further attract the attention of people around them.

[0023] Specifically, the card-jointing assembly includes a plurality of first springs 13 fixedly mounted on the inner wall of the mounting groove, the other ends of the plurality of first springs 13 are fixedly connected to the same card block 15, the inner walls of the plurality of first springs 13 are provided with telescopic rods 14, the two ends of the plurality of telescopic rods 14 are respectively fixedly connected to one side of the card block 15 and one side of the inner wall of the mounting groove, by moving the back plate 10 downward, the plug block 11 opened on one side of the back plate 10 will be inserted into the long groove opened by the fixed block 12, when the plug block 11 enters the long groove, the card block 15 set on one side of the plug block 11 will be squeezed and move toward the mounting groove opened by the plug block 11, when the mounting groove and the square groove are on the same horizontal line, the plurality of first springs 13 will be reset, thereby driving the card block 15 to move into the square groove, and then a fixed card connection is formed.

[0024] When in use: by placing the fixing frame 2 on the top side of the desktop 1, and then starting the motor 6 to drive the bidirectional screw 7 to rotate, the two sliding blocks 8 slidingly installed on the outside of the bidirectional screw 7 will move away from each other respectively, and then move toward the two card slots 9. When the two sliding blocks 8 move to the bottom, the fixing frame 2 and the desktop 1 form a fixed card connection. Because the table is large, it effectively prevents thieves from directly moving the entire chassis body 3 away. When thieves are about to steal electronic parts in the chassis body 3, they often open the back panel 10 on one side of the chassis body 3 first. Because the back panel 10 is carded in the square slot by the card block 15, it is not easy to directly pull the back panel 10. The card block 15 will be disengaged from the square groove, so the thief often uses the unlocking tool he carries with him to try to open the lock hole 18 provided in the fixed block 12. When the unlocking tool is inserted into the lock hole 18, the other end of the unlocking tool will hit the push plate 25. When it hits the push plate 25, it can drive the push plate 25 to move toward the card block 15. At this time, the handle on the top side of the back plate 10 can be pulled to pull up the back plate 10, because the unlocking tool used by the thief cannot squeeze the squeezing block 20, and when the squeezing block 20 is not squeezed, the squeezing rod 21 will not move toward the power-off switch 22, so that the controller 23 is in a normal operating state. When the back plate 10 is pulled up, the distance between the magnet 16 and the induction coil 17 becomes farther, thereby changing the magnetic field. This change will cause the current in the induction coil 17 to change. When the current in the induction coil 17 changes, the alarm system will be triggered, and then the magnetic alarm 24 arranged on the top side of the chassis body 3 will be able to sound an alarm, which can serve as a warning to the thief and further attract the attention of the surrounding personnel. Through the provided extrusion block 20, extrusion rod 21 and second spring 19, when the correct key is inserted into the lock hole 18, the key will contact the extrusion block 20, and then the extrusion block 20 will move downward to bring The other end of the movable squeezing rod 21 moves toward the power-off switch 22. When the squeezing rod 21 is pressed against the power-off switch 22, the power between the power-off switch 22 and the controller 23 will be cut off. When the controller 23 is powered off, the magnetic alarm 24 and the induction coil 17 will also be powered off. This prevents the magnetic alarm 24 from sounding an alarm when personnel are replacing electronic parts in the chassis body 3. When the correct key is pulled out, the squeezing block 20 can be driven to move up by resetting the second spring 19. Then the squeezing rod 21 can be moved away from the power-off switch 22. Then the controller 23 resumes power supply, and the induction coil 17 and the magnetic alarm 24 can operate normally again.
