[0028] Specifically, the limit block 601 facilitates the limiting and fixing of keyboards 2 of different lengths, providing high flexibility.

[0029] The movable block 603 is threadedly connected to a threaded rod 604. The threaded rod 604 has two opposite thread lines corresponding to the two movable blocks 603. The rear end of the threaded rod 604 is provided with a bearing 605, and the rear end of the bearing 605 is fixedly connected to the inner wall of the placement groove 101.

[0030] Specifically, rotating the threaded rod 604 facilitates the movement of the two moving blocks 603 towards or away from each other.

[0031] The threaded rod 604 passes through the placement groove 101 at its front end, and a first bevel gear 606 is provided at the front end of the threaded rod 604. A second bevel gear 607 meshes with the first bevel gear 606. A rotating rod 608 is provided at one end of the two second bevel gears 607 that are close to each other. A handle 610 is provided on the rotating rod 608. Bearing seats 609 are symmetrically provided on the left and right sides of the rotating rod 608. The lower end of the bearing seat 609 is fixedly connected to the bottom end of the groove 102.

[0032] Specifically, rotating the handle 610 drives the rotating rod 608 and the second bevel gear 607 to rotate, and the second bevel gear 607 in turn drives the first bevel gear 606 and the threaded rod 604 to rotate.

[0033] The mounting component 7 includes a mounting block 701 and a mounting groove 702. The lower end of the movable frame 3 is symmetrically provided with mounting blocks 701. The mounting blocks 701 are engaged with the housing 1, and the housing 1 is provided with mounting grooves 702 corresponding to the mounting blocks 701.

[0034] Specifically, the combination of the mounting block 701 and the mounting slot 702 facilitates the rapid positioning of the movable frame 3.

[0035] The front end of the mounting block 701 is engaged with the locking block 704. The front end of the mounting block 701 is provided with a locking groove 703 corresponding to the locking block 704. The front end of the locking block 704 is provided with a pull rod 705. The front end of the pull rod 705 is provided with a pull plate 707. A fixing block 706 is slidably connected to the pull rod 705. The upper end of the fixing block 706 is fixedly connected to the top end of the groove 102.

[0036] Specifically, through the coordinated use of the card block 704 and the card slot 703 structure, the card block 704 facilitates the limiting and fixing of the mounting block 701.

[0037] A second spring 708 is fitted onto the pull rod 705. The front end of the second spring 708 is fixedly connected to the fixing block 706, and the rear end of the second spring 708 is fixedly connected to the locking block 704.

[0038] Specifically, the elastic potential energy of the second spring 708 facilitates the return of the pull rod 705, pull plate 707, and locking block 704 to their original positions.

[0039] The working principle of this utility model is as follows:

[0040] In use, this utility model, through the combined structure of the housing 1, movable frame 3, and transparent cover 4, provides protection for the keyboard 2, preventing dust or liquid stains from accumulating on its surface when not in use. Simultaneously, the included first spring 5 prevents heavy objects from falling directly onto the keyboard 2 and causing damage. Rotating the handle 610 drives the rotating rod 608 and the second bevel gear 607 to rotate. The second bevel gear 607, in turn, drives the first bevel gear 606 and the threaded rod 604 to rotate. The rotation of the threaded rod 604, in turn, drives the two moving blocks 6... 03 The two moving blocks 603 move closer to each other, which, in conjunction with the movable rod 602 structure, causes the two limiting blocks 601 to move closer to each other. The limiting blocks 601 thus limit and fix the keyboard 2 of different lengths, which is highly flexible. When it is necessary to remove the keyboard 2, pull the pull plate 707 forward. The pull plate 707 drives the pull rod 705 and the locking block 704 to move forward. The locking block 704 compresses the second spring 708. At the same time, the locking block 704 separates from the slot 703, which makes it easy to open the movable frame 3, thus facilitating the removal of the keyboard 2. The operation is simple.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
