It is a three ta[er sleeve of logging cable composed of three metal sleeves, including the outer sleeve, the middle sleeve and the inner sleeve. The outer cylindrical surface of the outer sleeve has a stepped cylindrical surface, and one of the cylindrical surfaces has a keyway and a positioning hole for radial anti rotation. The outer sleeve has an inner conical surface, the middle sleeve has an outer conical surface and an inner conical surface, the inner sleeve has an outer conical surface and an inner cylindrical hole, the inner conical surface of the outer sleeve and the outer conical surface of the middle sleeve, and the inner conical surface of the middle sleeve, The taper of the outer cone of the inner sleeve is the same. The inner cone of the outer sleeve interacts with the outer cone of the middle sleeve to clamp the outer steel wire of the logging cable. The inner cone of the middle sleeve interacts with the outer cone of the inner sleeve to clamp the inner steel wire of the logging cable. The inner cylindrical hole of the inner sleeve can pass through the cable core of the logging cable, so that the three cone sleeve of the logging cable is fixed on the end of the logging cable.
