[0040] One end of the fixed strip 6 away from the hydraulic rod 4 is rotatably connected to a stand column 12, the stand column 12 being fixedly connected in the box body 1.

[0041] The inner side of the mechanical claw 26 is provided with an anti-skid piece 44.

[0042] The side surface of the support block 28 away from the connecting plate 29 is provided with a conductive ring 37 which is located outside the rotating shaft 36 and connected with the electric clamp jaw 34.

[0043] Specifically, the hydraulic rod 4 is started to push the adjusting plate 5 to adjust the position, facilitating the subsequent cutting of the cable protection pipe. The cable protection pipe to be cut is placed on the adjusting plate 5, and after the device is started, the electric clamp jaw 34 located on the left side of the mechanical claw first acts to clamp and fix one end of the cable protection pipe. The motor 11 is started to drive the lead screw 16 to rotate, so that the lead screw nut 18 moves along the lead screw 16, and then drives the electric clamp jaw 34 and the clamped cable protection pipe to move to the specified cutting position through the support block 28 and other components. Then the hydraulic cylinder 2 is started, the output end of which pushes the movable plate 8 to move downward, and the movable plate 8 drives the limiting plate 13 to move downward, so that the movable rod 15 is lowered when the movable plate 8 is lowered, the connecting rod 23 is lowered, the transmission is realized, the mechanical claw 26 acts, and the closure is realized to further limit and clamp the cable protection pipe.

[0044] The electric disc cutting knife 19 starts to work. Through the action of the lead screw 16 and the lead screw nut 18 and the mechanical claw 26 and the electric clamp jaw 34, the protection pipe body is driven to move, and when the cutting on one side of the protection pipe body is completed, the movement of the lead screw nut 18 causes the action force between the rotating mechanism 42 and the stop column 10, so that the end of the sleeve pipe 33 away from the support block 28 is extruded between the stop column 10, the sleeve pipe 33 slides on the connecting strip two 30 towards the support block 28, and the spring 38 is compressed at the same time. The guide block two 39 slides in the movable groove two 41 on the rotating column 40. Since the movable groove two 41 is a linear groove combined with a spiral groove, the rotating column 40 rotates, and then drives the connecting column 35 and the electric clamp jaw 34 to rotate, so as to adjust the angle of the cable protection pipe and make it rotate half a turn. In this process, the guide block one 31 sliding in the movable groove one 32 provided on the sleeve pipe 33 can guide the sliding of the sleeve pipe 33 because it is fixed on the connecting strip two 30, and prevent it from rotating, and the spring 38 and other components play a buffering role. After rotating half a turn, the sleeve pipe 33 is restored to the original position by the spring 38, so as to facilitate the extrusion again next time. At the same time, the anti-skid piece 44 prevents the electric clamp jaw 34 from not being able to grip the protection pipe body when clamping;

[0045] After the end of the rotation of a half turn, the protection tube body is pushed back to the adjusting plate 5 through the moving mechanism 43, and the electric clamping jaw 34 is rotated by a half turn again through the reciprocating movement of the screw nut 18 again, so as to be restored to the initial position, at this time, when the electric clamping jaw 34 clamps the protection tube, the damage of the electric disc cutting knife 19 to the electric clamping jaw 34 can be avoided, then the same principle can be used to move the protection tube body back to cut the opposite position of the cutting side again, after the cutting is completed, the electric disc cutting knife 19 stops working, the mechanical claw 26 and the electric clamping jaw 34 are loosened, the hydraulic cylinder 2 drives the movable plate 8 and other components to reset, and the next cutting operation is waited.

[0046] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art in the technical field without departing from the purpose of the present application.
