The utility model discloses a cable stripping and cutting machine. An opening (5) in an axial direction is sawed in an end part of a section of steel pipe (1) and the width of the opening (5) is greater than or equal to the thickness of a blade (4); a clamping plate (3) fixing the blade is welded on the steel pipe (1); an opening of a clamping groove (3) is towards to the opening (5) and the width of the clamping groove (3) is the same with that of the opening (5); screw holes are arranged in two sides of the clamping groove (3), and screws (2) are arranged in the screw holes; and the inner diameter of the steel pipe (1) is matched with the diameter of a cable. Compared with the prior art, by using the cable stripping and cutting machine, it only takes 1-2 minutes, which is one-tenth or one-fifth of the time of the prior art, to strip and cut a cable of 1 m, while it takes 10 minutes in the prior art. Therefore, working time is greatly reduced and working efficiency is improved. To sum up, the cable stripping and cutting machine overcomes disadvantages that many people are required, skills are difficult to learn, and hands are easy to cut in a traditional cable stripping and cutting operation; and the cable stripping and cutting machine is advantaged by simple manufacture, low cost, easy operation, perfect safety, good practicability, high efficiency and the like.
