Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a clamping device based on silent keyboard assembly. Background Art

[0002] Silent keyboards are favored by more and more users because they produce less noise when typing, especially in places that require a quiet environment, such as offices and libraries. During the assembly process of the silent keyboard, it is necessary to ensure the precise alignment and fixation of each component to ensure the performance and service life of the keyboard. The clamping device plays a key role in this precision assembly process. It can ensure the stability and accuracy of the keyboard components during the assembly process. However, most of the existing clamping devices for assembling keyboard caps can only achieve a clamping effect and cannot quickly loosen the keyboard cap. At the same time, it cannot automatically press the keyboard cap into the keyboard shaft and requires manual pressing, which increases the time for assembling the silent keyboard and reduces the efficiency of assembling the silent keyboard.
