High-precision sock cutting device

The utility model relates to the technical field of sock production, in particular to a high-precision sock cutting device which comprises a supporting frame body and a supporting plate, the top end of the supporting frame body is fixedly connected with the supporting plate, and the left side and the right side of the supporting frame body are both fixedly connected with bases. According to the sock cutting device, by installing a buffer pad, when socks are cut, two second air pumps are started to drive a fixed pressing plate to move downwards at the same time, so that the buffer pad is attached to the tops of the front side and the rear side of a sock cutting area to fix the socks, and when the buffer pad makes contact with the socks, impact force generated when the socks are extruded can be buffered through elastic force of springs; the socks are not prone to being damaged while being fixed, the friction force between the socks is increased while the socks are not prone to being damaged through the bufferin
