The invention relates to the technical field of thread strippers, A bi-directional cutting type quick stripper is disclosed, including a tangent channel, a horizontal knife controller, A knife outletbase and a longitudinal knife controller, The cutter discharge base comprises a longitudinal cutter outer ring layer, a longitudinal cutter discharge layer, a transverse cutter discharge layer and a transverse cutter outer ring layer, wherein the longitudinal cutter guide pillar slides in the longitudinal cutter spiral groove of the longitudinal cutter controller to drive the longitudinal cutter to slide up and down in the radial direction, and the transverse cutter slides in the transverse cutter spiral groove of the transverse cutter controller to drive the transverse cutter to slide up anddown in the radial direction through the transverse cutter guide pillar. The device not only meets the requirements of both transverse and longitudinal cutting, but also can simultaneously cut off theshorter thread head and the longer thread head without cutting in multiple sections. The bi-directional cutting type quick stripper is not only suitable for wires and cables with various specifications, but also has the advantages of small size, light weight, convenient operation, regular cut, high stripping efficiency, strong practicability, safety and popularity.
