In the enlargement device, although the actual travel keeps unchanged during adjustment of a blade side gap, the range scope in the travel switch reflected by the swinging bar is enlarged by multiple times, thereby avoiding the exceeding of the extreme range of the blade side gap, preventing the seizing phenomenon of a blade side gap adjusting device, reducing the failure probability and accident handling time, prolonging the service life of the blade side gap adjusting device and effectively reducing the consumption of spare parts and production cost.
