Through the arrangement of the contact switch one 17 and the contact switch two 18, the position of the rack 9 can be quickly detected. When the contact block at the top of the rack 9 contacts the contact switch one 17, the rack 9 is in the retracted state, and at this time the locking pin 16 is separated from the lock hole. When the slider at the bottom of the rack 9 contacts the contact switch two 18, the rack 9 is in the extended state, and at this time one end of the locking pin 16 is inserted into the lock hole to enter the locked state; when locking, if an external force is applied to drag the guide rail base 2 to separate it from the fixed base 1, the locking pin 16 will move to drive the rack 9 to move, and the slider of the rack 9 is separated from the contact switch two 18. At this time, it is an abnormal state. Through the action of the circuit board 10, the alarm 21 can be quickly started to give an alarm.

[0043] Among them, the electric locking assembly further includes an electronic key 22 wirelessly connected to the electronic lock 11. The electronic lock 11 is electrically connected to the circuit board 10. Through the arrangement of the electronic lock 11 and the electronic key 22, the device can be quickly locked and unlocked, and has high operation convenience; the alarm 21 is electrically connected to the circuit board 10 to facilitate quick alarm operation when the device is in an abnormal state.

[0044] Among them, a plurality of fixing screws 5 are fixedly connected to the bottom of the fixed base 1, and a wing nut 6 is threadedly connected to the outside of each group of fixing screws 5, so as to quickly fix the whole device to the display table by means of the fixing screws 5 and the wing nuts 6 during use.

[0045] Among them, a double-sided adhesive is fixedly adhered to the bottom surface of the fixed base 1, so as to facilitate quick adhesive installation when it is inconvenient to drill holes for fixation on the display tabletop.

The fixing member 20 is Z-shaped, with one end being limited and engaged with the limiting step 102, and the other end being installed inside the connecting groove 101 and fixedly connected to the bottom of the guide rail seat 2 through a fastening screw. Through the setting of the fixing member 20, it is convenient for users to selectively strengthen the installation strength of the guide rail seat 2 according to actual needs during use, so as to improve the stability of the overall structure.

[0047] The working principle of this embodiment: During use, the fixed base 1 can be fixed on the display tabletop through the fixed screw 5 or double-sided adhesive; then move the two groups of moving components 3 to expand them on the guide rail seat 2. After that, unfold the notebook computer, place the two ends of its bottom on the supporting plate 404, and place the screen of the notebook computer between the front clamping plate 402 and the rear clamping plate 403 of the clamping claw 4. Then push the moving component 3 in the reverse direction to move it until the inner side of the base plate 401 of the clamping claw 4 is closely attached to the outer side of the screen; then install the guide rail seat 2 into the fixed base 1. At this time, the end of the abutting shaft 13 can be closely attached to the inner wall of the fixed base 1, and the toothed plate 12 is stably connected to the tooth groove 304 of the moving seat 301 and cannot move. At this time, the moving component 3 cannot be pulled; then align the electronic key 22 with the installation position of the electronic lock 11 and send a locking instruction. At this time, the reduction motor 8 drives the gear 15 to drive the rack 9 to move, so that the locking pin 16 at one end of the rack 9 is inserted into the lock hole of the fixed base 1 for locking, ensuring that the guide rail seat 2 is stably placed in the fixed base 1. Conversely, it can also be unlocked through the electronic key 22; when the locking pin 16 is in the locked state, if an external force is applied to drag the guide rail seat 2 to separate it from the fixed base 1, the locking pin 16 will move to drive the rack 9 to move, and the slider of the rack 9 will separate from the contact switch II 18. At this time, it is an abnormal state. Through the action of the circuit board 10, the alarm 21 can be quickly started for alarm to remind relevant staff and prevent the notebook computer from being stolen, with high safety.
