[0003] However, the existing cable sheath stripping devices have single functions and can only strip specific types of cable layers (such as the armor layer or the insulation layer), unable to meet the complex and changeable cable processing requirements, which limits the application scope of the devices. Secondly, most of the existing cable sheath stripping devices lack effective cable feeding and straightening mechanisms, resulting in the need for manual assistance in adjusting the cable during the stripping process, increasing the operation difficulty and labor intensity. In addition, there are also many deficiencies in the existing devices in terms of the way of advancing and retracting the cutter, controlling the cutting length of the cable, and portability.

One of the cutting devices is automatic feed and retract, and the other is automatic cutting. The mechanism used for automatic feed and retract is an innovative design inspired by the three-jaw chuck.

[0018] The principles applied in this mechanism include the planetary gear train. The rotation directions of the planetary gears around the central sun gear are the same, and the moving distances are the same. When two bevel gears mesh and transmit motion, the motion direction will be rotated 90 degrees on the plane. When the lead screw and the lead screw nut cooperate, if the lead screw nut rotates around a fixed axis and the lead screw nut has only one degree of freedom, the lead screw nut will move linearly along the lead screw without rotation.

[0019] In summary, this mechanism realizes the function of automatic feed and retract.

[0020] Compared with the traditional three-jaw chuck, this mechanism has the advantage of higher precision. There are two common types of three-jaw chucks. In either type, the forward or backward movement of the clamping mechanism depends on the friction with the part. Therefore, compared with the three-jaw chuck, this mechanism is not easily worn and has a longer service life. Moreover, when replacing the internal parts of this mechanism, since there are more internal parts in this mechanism than in the three-jaw chuck, the replaced parts are generally smaller and the cost is lower. At the same time, because there is more empty space inside this mechanism, it also has the characteristic of being lightweight.

[0021] The inspiration for the automatic cutting mechanism comes from the form in which the lathe drives the three-jaw chuck to rotate. A stepping motor is used to drive the overall rotation of the tool-carrying part of the mechanism, and gear transmission is used, which has high precision and strong load capacity.
