Description

Technical Field

[0001] The utility model relates to the technical field of keyboard bottom plate production, in particular to a material cutting device for keyboard bottom plates. Background Art

[0002] During the production process of the keyboard base in the factory, there will be excess parts on both sides of the keyboard base, which need to be cut to make it meet the product design and use requirements. The purpose of cutting is to remove excess material and make the keyboard base more tidy and beautiful, and facilitate subsequent installation and use.

[0003] The prior art patent document with publication number CN219255746U provides a cutting device for a keyboard base plate. The keyboard base plate is placed on a supporting plate, and then the hand wheel is twisted to rotate the threaded rod two. Since the thread directions of the two threaded holes are opposite, the rotation of the threaded rod two will drive the two fixed rods to move closer to each other. By moving the two fixed rods closer to each other, the gap between the two fixed rods is gradually reduced until the keyboard base plate is fixed. Then the keyboard base plate is cut by the cutting head. The cutting device is convenient for fixing the keyboard base plate, and the fixation is relatively stable, which prevents position displacement or falling when cutting the keyboard base plate. The cutting is more precise and more convenient to use. When the cut keyboard base plate needs to be taken out, the user can take it out by turning the hand wheel in the opposite direction to move the two fixed rods away from each other. The material is convenient to take out and the operation is more convenient.
