[0062] Working principle of the utility model:

[0063] S1, according to the construction scene demand, such as, the cable has not been pulled, the end part is easy to find, the cable end part can be directly placed between the pressing block 213 and the limiting head 205, and for the cable laying a distance, the seabed environment is relatively dark, or the seabed environment is complex, the end part cannot be well found, the cable middle position can be directly placed close to the bevel groove 212 of the limiting head 205, and the limiting head 205 is rotated around the connecting seat 209 under the cooperation of the bevel groove 212, the torsion spring 210 is tightened, and after the cable is clamped, the limiting head 205 is reset and rotated to be closed under the cooperation of the torsion spring 210.

[0064] S2, according to the distance between the cables to be pulled, the driving sleeve 108 is rotated, and under the threaded transmission, the two screw rods 109 are flexibly displaced, the distance between the two mounting frames 104 is adjusted, and the simultaneous pulling operation demand of the cables with different distances is met;

[0065] S3, after the double-shaft motor 102 is connected with the external safe power supply, such as the safe power supply on the construction ship, the double-shaft motor 102 is controlled to work in the forward rotation, and the connecting plate 201 can be rotated by the cooperation of the hexagonal rod 106 and the movable sleeve 103, and then the two movable plates 202 are linked to rotate around the first positioning shaft 105 or the second positioning shaft 107 respectively, the auxiliary seat 208 is driven to move, and under the positioning action of the slide rod 211 and the guide seat 214, the auxiliary seat 208 is maintained in the horizontal state, the position of the slide rod 211 and the abutting block 213 does not change temporarily under the elastic support of the spring 207, and the limiting head 205 gradually approaches the abutting block 213 until the abutting block 213 and the limiting head 205 cooperate to complete the contact positioning of the cable, with the further rotation of one end of the movable plate 202, the slide rod 211 will slide in the storage sleeve 206, the spring 207 is compressed, the control electromagnet 215 is electrified to magnetically attract and lock the slide rod 211, the cable is well clamped, and then the cable can be pulled outward by a distance;

[0066] S4, when the double-shaft motor 102 is controlled to work in the reverse rotation, the movable plate 202 is reset to rotate, and the control electromagnet 215 is de-energized to work, so that the position of the abutting block 213 is no longer locked, and the cable is no longer stably clamped, at this time, when the movable plate 202 rotates, the limiting head 205 and the abutting block 213 are displaced and will not displace the cable;

[0067] S5, the operations of S3 and S4 are repeated, and the cable can be continuously pulled and processed;

[0068] S6, since the two movable plates 202 are designed in a circumferential array around a single connecting plate 201, when one movable plate 202 on one side pulls one cable outward, the movable plate 202 on the other side can pull another cable inward, and the bidirectional pulling demand can be met.
