The user uses a latch to pass through the interior of the through hole 12 and insert it into the limiting hole 11 to fix the position of the limiting plate 8. The plug 5 is inserted into the position of the card slot 4, and the latch is removed. The limiting plate 8 enters the interior of the splicing groove 7 under the thrust of the thrust spring 9, and the limiting block 15 is moved to the interior of the limiting groove 14 to fix the position of the limiting plate 8 to prevent the vibration during the operation of the equipment from causing the limiting plate 8 to retract into the interior of the receiving groove 6 and cause it to fall off.
[0026] Reference Figure 5 As shown, in this embodiment: one side of the limit block 15 is fixedly connected with a return spring 16, and one side of the return spring 16 is fixedly connected to one side of the inside of the placement groove 13. The user moves the limit plate 8 inward and retracts it into the inside of the receiving groove 6. The user uses a latch to pass through the inside of the through hole 12 and insert it into the limit hole 11 to fix the position of the limit plate 8. The limit block 15 is moved outward and retracted into the inside of the placement groove 13. At the same time, the return spring 16 accumulates force, and the plug 5 is inserted into the position of the card slot 4. The latch is removed, and the limit plate 8 enters the inside of the splicing groove 7 under the thrust of the thrust spring 9. The limit block 15 is released and driven to enter the inside of the limit groove 14 under the action of the return spring 16 to fix the limit plate 8.
[0027] Reference Figure 5 As shown, in this embodiment: sliding grooves 17 are provided on both sides of the placement groove 13, and sliding blocks 18 are fixedly connected on both sides of the limit block 15. After the user inserts the insertion block 5 into the card slot 4, the user takes out the latch to allow the limit plate 8 to enter the interior of the splicing groove 7, and releases the limit block 15. Under the action of the reset spring 16, the limit block 15 is driven to enter the interior of the limit groove 14 to fix the limit plate 8. During the movement of the limit block 15, the sliding grooves 17 on both sides slide inside the sliding block 18 to limit the limit block 15, thereby preventing the limit block 15 from shaking inside the limit groove 14 and making the fixation of the limit plate 8 unstable.
[0028] Reference Figure 3As shown, in this implementation scheme: both sides of the front end of the limit plate 8 are beveled edges, the user moves the limit plate 8 inward, retracts it into the interior of the receiving groove 6, uses a latch to pass through the interior of the through hole 12 and insert it into the limit hole 11, fixes the position of the limit plate 8, aligns the plug block 5 with the position of the card slot 4 and inserts it, removes the latch, and the limit plate 8 enters the interior of the splicing groove 7 under the thrust of the thrust spring 9.
