Referring to fig. 5, 6, 7 and 8, in the present embodiment, the first cover 40 has a first hook 41, and the first hook 41 is slidably engaged with the first engaging hole 3111 of the case 30 and is engaged with the locking slot 111 of the slide lock assembly 10; the second cover plate 50 has a second hook 51, and the second hook 51 is slidably engaged with the second engaging hole 3121 of the case 30 and abuts against the other end of the linkage lock assembly 20.

By providing the first hook 41 on the first cover plate 40, the sliding lock assembly 10 is conveniently driven to move to a preset position by being matched with the locking groove 111; when the slide lock assembly 10 moves to a predetermined position, the locking groove 111 and the first engagement hole 3111 can be offset to limit movement of the first hook 41 and the first cover 40, thereby facilitating improvement of stability of locking the first cover 40. By arranging the second clamping hook 51 on the second cover plate 50, when the sliding rod 22 pushes the locking head 23 to be abutted against the second cover plate 50 under the pushing action of the first cover plate 40, the locking head 23 stops the second clamping hook 51 to limit the movement of the second clamping hook 51 and the second cover plate 50, so that the stability of locking the second cover plate 50 is improved.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Finally, it should be noted that the above embodiments are merely for illustrating the technical solution of the present application and not for limiting, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present application may be modified or substituted without departing from the spirit and scope of the technical solution of the present application.

Claims (10)
