[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4A lubrication mechanism 16 is provided on the support frame 4. The lubrication mechanism 16 includes a guide pipe 160.

[0027] The specific implementation process of this utility model is as follows: In use, the cable 3 is passed through the gap between the driven roller 8 and the driving roller 10, and the cable 3 is brought into contact with the guide wheel 2. The telescopic end is driven to move by the hydraulic cylinder 5, so as to drive the connecting frame 6 to move, thereby driving the driven shaft 7 to slide along the inner wall of the support frame 4, and driving the driven roller 8 to move down, so that the driven roller 8 pushes the cable 3 to move, and the cable 3 is brought into contact with the driving roller 10 to clamp the cable 3, so that the first and second cutters cut into the sheath of the cable 3.

[0028] The output shaft is driven by motor 13 to rotate, which in turn drives pulley 14 to rotate. Under the transmission of V-belt 15, V-belt 15 drives pulley 12 to rotate, which in turn drives drive shaft 9 to rotate, and then drives drive roller 10 to rotate, so as to transport, cut and strip cable 3.

[0029] When the drive shaft 9 rotates, the limiting pad 172 can slide along the surface of the drive shaft 9 to guide the rotation of the drive shaft 9, avoiding the problem of rotational polarization of the drive shaft 9. With the structure of spring 174, telescopic rod 171, etc., the limiting pad 172 can always be in contact with the drive shaft 9 to ensure good contact effect of the limiting pad 172.

[0030] By pulling the end rod 162 to the left, the moving block 163 is moved, causing the spring 164 to deform and move the elastic plug 165. Under the pressure of the inner wall of the guide hole of the oil reservoir 161, the elastic plug 165 can be pushed out of the guide hole of the oil reservoir 161, thereby guiding the lubricating oil. In conjunction with the function of the guide pipe 160, the lubricating oil can be guided to lubricate the extension and retraction end of the hydraulic cylinder 5, thereby reducing the extension and retraction resistance of the hydraulic cylinder 5.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
