In combination with the first surrounding roller 214, the handle 5 and the second surrounding roller 223, the cutter can evenly surround the cable and cut a circle to complete the steel armor cutting, achieve fast and smooth cutting action, and improve cutting efficiency; in conjunction with the clamping structure 2, the ring cutter is suitable for the steel armor cutting requirements of cables of different specifications and types. The ring cutter can be used to ring cut the outer sheath and inner sheath of the cable. The blocking member 4 is adjusted to expose the cutting disc to the corresponding height and the required cutting layer thickness and match them. The operation is simple, convenient and fast, and can greatly improve the cable joint manufacturing process and speed.
