装置下压时可通过伸缩板下压升降板此时可通过弹簧的弹性势能带动升降板两侧安装的第二滑块在第二滑轨内部进行滑动此时可对装置进行快速复位提升了装置切割时的稳定性同时增加了装置使用的安全性。以术语表达这段话

When the device is pressed down, the lifting platform can be lowered and raised by the telescopic plate. At this time, the elastic potential energy of the spring can drive the second slider installed on both sides of the lifting platform to slide inside the second slide rail. This enables the device to be quickly reset, improving the stability of the device during cutting and increasing the safety of its use.
