Abstract: A device for testing pressure of keys of a full keyboard includes a variable-pitch test module mechanism. The variable-pitch test module mechanism includes multiple modules mounted on a base plate and probe modules provided corresponding to the variable-pitch test modules one by one; the variable-pitch test module includes a first driving device and a second driving device, the probe module is mounted on the second driving device, the second driving device is provided on the first driving device, the first driving device is configured to adjust a position of the probe module in an X direction, and the second driving device is configured to adjust a position of the probe module in a Y direction; and the probe module includes a lifting device and a probe for testing. The lifting device is connected to the probe and is configured to adjust a position of the probe in a Z direction.
