[0030] In this embodiment, when it is necessary to fix the grille plate 2, since the external connecting rod 4 is installed on the grille plate 2, then the grille plate 2 is pressed on the stepped frame 1, and at the same time, the insertion block 13 is inserted between the fitting ring 11 and a plurality of lateral pieces 18. Due to the one-way setting of the one-way piece 12, the one-way piece 12 can be stuck inside the clamping groove 14. Then the insertion block 13 is pressed on the follower sleeve 19, and a reaction force is generated under the action of the push spring 20, thereby ensuring the clamping stability between the one-way piece 12 and the clamping groove 14. And due to the sliding connection between the positioning rod 6 and the positioning groove 10, the sliding connection between the follower rod 8 and the follower groove 9, and the sliding connection between the insertion block 13 and the fitting ring 11, not only the axial limit of the insertion block 13 is ensured, but also the circumferential direction is fixed, thus completing the fixing process.

[0031] Please refer to Figure 3 and Figure 4 , as an implementation manner of the unlocking mechanism: the unlocking mechanism includes an unlocking sleeve 17 and a lateral piece 18, one end of the lateral piece 18 is connected to the receiving rod 5, the other end of the lateral piece 18 is connected to the unlocking sleeve 17, a plurality of insertion blocks 13 are respectively attached to the lateral piece 18, and the insertion blocks 13 are slidably connected to the unlocking sleeve 17.

[0032] More specifically, when it is necessary to disconnect the connection, pulling the handle 7 can drive the unlocking sleeve 17 to slide downward, then the unlocking sleeve 17 abuts against a plurality of one-way pieces 12, and then the one-way pieces 12 expand outwards, so as to disconnect the clamping connection between the one-way pieces 12 and the card slots 14, and then the insertion block 13 can be pulled out. Since the insertion block 13 is slidably connected to the grille plate 2 and the external connecting rod 4 presses on the grille plate 2, the fixation between the grille plate 2 and the stepped bracket 1 can be released, thus completing the disconnection process.

[0033] In summary, when the overall device is in use or operation: when it is necessary to fix the grille plate 2, since the external connecting rod 4 is installed on the grille plate 2, then the grille plate 2 is pressed on the stepped bracket 1, and at the same time the insertion block 13 is inserted between the fitting ring 11 and a plurality of lateral pieces 18. Due to the one-way setting of the one-way pieces 12, the one-way pieces 12 can be clamped in the card slots 14. Then the insertion block 13 presses on the follower sleeve 19, and a reaction force is generated under the action of the push spring 20, thus ensuring the clamping stability between the one-way pieces 12 and the card slots 14. And due to the sliding connection between the positioning rod 6 and the positioning slot 10, the sliding connection between the follower rod 8 and the follower slot 9, and the sliding connection between the insertion block 13 and the fitting ring 11, not only the axial limit of the insertion block 13 is ensured, but also the circumferential direction is fixed, thus completing the fixing process.

[0034] When it is necessary to disconnect the connection, pulling the handle 7 can drive the unlocking sleeve 17 to slide downward, then the unlocking sleeve 17 abuts against a plurality of one-way pieces 12, and then the one-way pieces 12 expand outwards, so as to disconnect the clamping connection between the one-way pieces 12 and the card slots 14, and then the insertion block 13 can be pulled out. Since the insertion block 13 is slidably connected to the grille plate 2 and the external connecting rod 4 presses on the grille plate 2, the fixation between the grille plate 2 and the stepped bracket 1 can be released, thus completing the disconnection process.
