A front baffle 13 is provided on the inner side of the front end of the bottom plate of the fixing sleeve 1, and when the crystal head is inserted into the fixing sleeve 1, the front baffle 13 blocks the front end face of the crystal head to prevent the fixing sleeve 1 from sliding backward on the crystal head. A limiting protrusion 14 is provided on the inner side of the middle part of the bottom plate of the fixing sleeve 1, and the limiting protrusion 14 can be stuck in the groove on the lower surface of the crystal head to prevent the fixing sleeve 1 from sliding forward on the crystal head, and the limiting protrusion 14 cooperates with the front baffle 13 to enable the fixing sleeve 1 to be stably installed on the crystal head.
[0029] The rear end cover 4 blocks the upper half of the rear end of the fixing sleeve 1, and a makeshift space is provided in the lower half of the rear end of the fixing sleeve 1. The makeshift space corresponds to a crystal head slot 12 provided in the fixing sleeve 1 for the crystal head to pass through. The rear end cover 4 is provided with two rectangular first keyholes 41 and second keyholes 42, the first keyhole 41 is on the top, and the second keyhole 42 is on the bottom. The second keyhole 42 is connected to the makeshift space corresponding to the crystal head slot 12.
[0030] The shrapnel pressing member 2 is connected to the inner surface of the rear end cover 4 at a position between the first keyhole 41 and the second keyhole 42. The shrapnel pressing member 2 includes a front extension plate 21, a pressing block 22, and a contact plate 23. The front extension plate 21 is arranged as a rectangular plate, vertically fixed on the inner surface of the rear end cover 4 and parallel to the bottom plate of the fixing sleeve 1. The pressing block 22 is connected to the lower side of the front end of the front extension plate 21. The contact plate 23 is arranged as a wedge-shaped plate with the tip facing upward, connected to the upper side of the front end of the front extension plate 23. The contact plate 23 is opposite to the first keyhole 41 front and back, and the inclined surface faces the direction of the first keyhole 41.
[0031] The shrapnel support member 3 is arranged below the shrapnel pressing member 2. A shrapnel slot 11 for the shrapnel of the RJ45 connector to pass through is provided between the shrapnel pressing member 2 and the shrapnel support member 3. The RJ45 connector slot 12 is located below the shrapnel support member 3. The shrapnel pressing member 2 and the shrapnel support member 3 abut against the shrapnel of the RJ45 connector from the upper and lower sides.
[0032] The shrapnel support member 3 includes two support claws 31 and support blocks 32 arranged on each support claw 31. The support claws 31 are arranged as straight rods. The rear ends of the support claws 31 are connected to the rear end cover 4 corresponding to both ends of the second keyhole 42 or the side walls of the fixing sleeve 1.

When the locking device is unlocked, the two plug boards of the key are aligned and inserted into the two key holes on the locking device. The second plug board 52 passes through the second key hole 42 and first contacts the inner sides of the two supporting claws 31, and gradually spreads the two supporting claws 31 outwards, so that the distance between the two supporting claws 31 is greater than the width of the crystal head elastic piece, and the support under the crystal head elastic piece is lost. Immediately afterwards, the first plug board 51 passes through the first key hole 41, the front end of the first plug board 51 abuts against the contact plate 23, and moves forward along the inclined surface of the contact plate 23, gradually pressing down the contact plate 23, and then driving the pressing block 22 to press down the crystal head elastic piece, so that the locking state between the crystal head elastic piece and the device interface is released, facilitating the removal of the crystal head.
