[0029] Preferably, the base 1 is provided with a groove 2. Specifically, the groove 2 is arranged on the upper surface of the base 1, and the cable is placed in the groove 2 when cutting the cable, so as to prevent the cable from rolling as much as possible and to achieve the positioning of the cable.

[0030] Preferably, the cutting mechanism comprises a cutter 3, the first section 101 is fixedly connected with a mounting frame 4, the mounting frame 4 is provided with a hydraulic cylinder 5, and the cutter 3 is fixedly connected with the output end of the hydraulic cylinder 5. Specifically, the mounting frame 4 is L-shaped, the hydraulic cylinder 5 is fixedly connected to the top end of the mounting frame 4, the output end of the hydraulic cylinder 5 penetrates the top wall of the mounting frame 4 and is fixedly connected with the cutter 3, and the extension and contraction of the hydraulic cylinder 5 provides the power required when the cutter 3 cuts the cable.

[0031] Further, the second section 102 is provided with an extension 6, the first section 101 is provided with a sliding groove 7 matched with the extension 6, and the extension 6 is in sliding connection with the sliding groove 7. Specifically, the sliding groove 7 is arranged on the two side walls of the mounting groove, and the extension 6 is a protruding structure on the two side walls of the second section 102. Through the connection of the extension 6 and the sliding groove 7, the second section 102 can slide relative to the first section 101.

[0032] Further, the mounting frame 4 is provided with a guide rail 8, the cutter 3 is provided with a sliding part 9 matched with the guide rail 8, and the sliding part 9 is in sliding connection with the guide rail 8. Specifically, the guide rail 8 is arranged on the two inner walls of the mounting frame 4, and the sliding part 9 is arranged on the two sides of the cutter 3. The end of the sliding part 9 is a convex structure, and the sliding part 9 and the guide rail 8 are in sliding connection. The cutter 3 is limited, so as to improve the stability of the cutter 3 when lifting.

[0033] As an alternative to the above-mentioned electric push rod driving the second section 102 to slide, the power assembly comprises a first abutting rod 10 fixed to the sliding part 9, and a second abutting rod 11 provided on the extension part 6, the second abutting rod 11 being located in the movement stroke of the first abutting rod 10. A first spring 12 is provided between the extension part 6 and the sliding groove 7. Specifically, the first abutting rod 10 is fixed to the lower surface of the sliding part 9, and is located above the second abutting rod 11, and a through hole 19 or the like is provided between the two for the sliding of the first abutting rod 10. The second abutting rod 11 is arranged in parallel with the second section 102, and a wedge surface is provided at the end of the second abutting rod 11 away from the extension part 6, the wedge surface being located in the movement stroke of the bottom end of the first abutting rod 10. The vertical distance between the first abutting rod 10 and the second abutting rod 11 is slightly smaller than the distance between the cutter 3 and the upper surface of the base 1. In this way, when the cutter 3 is lowered to cut the cable, the first abutting rod 10 is driven to move downward synchronously by the sliding part 9. When the cutter 3 is about to contact the upper surface of the base 1, the first abutting rod 10 abuts against the wedge surface of the second abutting rod 11, thereby driving the second abutting rod 11 to slide, storing the force of the first spring 12, and driving the second section 102 to move synchronously through the extension part 6, so as to passively generate a gap between the second section 102 and the first section 101. After the cable is cut, the cutter 3 is controlled to move upward by the hydraulic cylinder 5, thereby driving the first abutting rod 10 and the second abutting rod 11 to gradually move away from each other. At this time, the elastic force of the first spring 12 is released, thereby driving the second section 102 to automatically reset, so as to compensate for the gap between the second section 102 and the first section 101.

[0034] Further, the second abutting rod 11 is provided with a locking member for fixing the position of the second section 102.

The locking rod 13 is preferably a cylindrical rod, and a locking hole 16 is provided on the inner top wall of the sliding groove 7. The width of the active slot 14 is smaller than the width of the second abutting rod 11. In this way, when the cable is not cut, the locking rod 13 is inserted into the locking hole 16 under the elastic force of the second spring 15, thereby fixing the position of the second section 102, so as to improve the stability when the second section 102 is connected to the first section 101.

[0035] Further, the locking rod 13 is provided with an unlocking rod 17, the unlocking rod 17 is located on the movement stroke of the first abutting rod 10. Specifically, the unlocking rod 17 is also vertically arranged, and the locking rod 13 and the unlocking rod 17 form a U-shaped structure, the end of the unlocking rod 17 penetrates through the movable slot 14 to above the wedge surface of the second abutting rod 11, and is located on the movement stroke of the first abutting rod 10. The setting is to make the first abutting rod 10 abuts against the end of the unlocking rod 17 first during the cutting of the cable, and drives the unlocking rod 17 and the locking rod 13 to move downward synchronously, and stores the force of the second spring 15, at this time, the locking rod 13 is pulled out of the locking hole 16, so as to realize the passive unlocking of the second section 102. In the subsequent abutting process of the first abutting rod 10 and the second abutting rod 11, the second section 102 is passively moved. After the cable is cut, the first abutting rod 10 and the second abutting rod 11 gradually move away, and the elastic force of the first spring 12 is released first to drive the locking rod 13 to coincide with the locking hole 16. At this time, the elastic force of the second spring 15 is released, so that the locking rod 13 is inserted into the locking hole 16 again to passively lock the second section 102.

[0036] Further, the base 1 is also provided with a fixing assembly 18. Specifically, the fixing assembly 18 can be a cooperation structure of a pneumatic cylinder and a pressing plate, and the pressing plate is driven to rise and fall by the extension and contraction of the output end of the pneumatic cylinder, so as to realize the fixing and loosening of the cable.
