[0002] The space bar cap is a type of keycap, usually refers to the keycap of the space bar on a mechanical keyboard. Since the space bar is one of the most commonly used keys on the keyboard, its keycap is also one of the most important keycaps in the keyboard. The space bar keycap is the keycap on the keyboard used to enter the space character, usually a relatively large keycap, because the space bar is usually relatively large. The function of the space bar keycap is to protect the space bar, keep it clean and tidy, and prevent dust and dirt from entering the inside of the space bar. The material and craftsmanship of the space bar keycap vary according to the brand and model of the keyboard, but generally speaking, common space bar keycap materials include ABS plastic, PBT plastic, metal, etc. Among them, ABS plastic is the most common space bar keycap material on the market, because it is cheap, easy to process and manufacture, and feels comfortable. PBT plastic has better wear resistance and oil resistance, so it is also favored by many users.

Some users have a great preference for some special space bar caps, but the existing space bar caps are all integral and occupy a large space after being placed. For this reason, we propose a multi-angle foldable space bar cap bracket. Utility Model Content
