A fastening sleeve 402 is connected to the outside of the spring shaft 401. The fastening sleeve 402 can fit with the holes on an external frame. The fastening sleeve 402 is a conical split structure, and the diameter of each group of fastening sleeves 402 gradually decreases from the mounting plate 301.

[0024] As Figures 1 - 3 shown, a digital processor 5 is installed in the machine shell 1. The high-speed digital processor 5 is used as the output core. 32-bit double-precision algorithms are applied in software to generate arbitrary high-precision waveforms for each phase. Due to the integrated structure, all parts are closely combined, the data transmission distance is short, the structure is compact, and the problem of few output waveform points caused by long data communication lines and narrow frequency bands in the notebook computer direct control type measuring and controlling instrument is overcome. And ventilation meshes 10 are fixedly provided on both side walls of the machine shell 1. The ventilation meshes 10 can ensure that the heat in the machine shell 1 is quickly discharged.
