The extrusion sleeve 129 is used for extruding the elastic three-jaws 128, so that the elastic three-jaws 128 are deformed and extrude the core of the inserted rivet 122. The extrusion sleeve 129 is in threaded transmission cooperation with the locking stud 132. An extrusion sleeve driving gear 130 is also fixedly sleeved on the extrusion sleeve 129. The extrusion sleeve driving gear 130 is in meshing and sliding cooperation with the gear column 127.

[0022] The working principle of a ship cable laying and fixing device disclosed by the present invention is as follows: The cable is laid on the surface of the ship board, and then a cable fixing member 116 is buckled on the cable. At this time, the device is moved over so that the stable support 101 contacts the surface of the ship board. The sliding table 103 is moved so that the drill bit 115 moves to the middle of the cable fixing member 116. Then, the first electric cylinder 105 is controlled. The telescopic rod of the first electric cylinder 105 drives the moving platform 107 to move downward. At this time, the drill bit 115 on the moving platform 107 will also move synchronously. At the same time, the first driving motor 111 is started. The output shaft of the first driving motor 111 drives the drill bit 115 to rotate, and then drives another drill bit 115 to rotate through the first transmission chain 114. At this time, the two drill bits 115 rotate simultaneously. As the telescopic rod of the first electric cylinder 105 moves, the drill bit 115 will contact the cable fixing member 116 and drill through holes in the cable fixing member 116 and the ship board so as to put the blind rivet 122 into them. Subsequently, the first driving motor 111 is stopped or the first driving motor 111 is reversed and then stopped, and then the telescopic rod of the first electric cylinder 105 is controlled to contract so that the drill bit 115 is withdrawn from the drilled through holes.Move the sliding table 103 to the other end of the guiding sliding rod column 102 (there is magnetic cooperation between the sliding table 103 and the two stabilizing brackets 101, and there is magnetic cooperation between the stabilizing brackets 101 and the ship's board). At this time, the blind rivet guide rail 121 is aligned with the through hole drilled by the drill bit 115. Then, control the extension of the telescopic rod of the second electric cylinder 118, so that the telescopic rod of the second electric cylinder 118 drives the pulling plate 125 to move towards the ship's board (at the same time, the pulling plate bracket 124 slides on the support slide rod 120 of the top fixing plate). The movement of the pulling plate 125 will drive the elastic three-jaw 128 to move. Before this, the user places a blind rivet 122 on each of the two blind rivet guide rails 121 (or multiple can be placed to facilitate the next point for fixing the cable), slides the blind rivet 122 to the through hole position of the blind rivet guide rail 121, and lets the blind rivet 122 fall into the through hole drilled by the drill bit 115. As the elastic three-jaw 128 moves, the core of the blind rivet 122 will be inserted into the elastic three-jaw 128. Then, start the second driving motor 131. The output shaft of the second driving motor 131 drives the gear column 127 to rotate. The two gear columns 127 rotate synchronously through the second transmission chain 126. The rotation of the gear column 127 drives the extrusion sleeve driving gear 130 to rotate. The rotation of the extrusion sleeve driving gear 130 drives the extrusion sleeve 129 to rotate. The extrusion sleeve 129 will rotate threadedly on the locking stud 132 and move axially along the locking stud 132. At this time, the extrusion sleeve 129 will squeeze and narrow the elastic three-jaw 128, so that the elastic three-jaw 128 squeezes and fixes the core of the blind rivet 122. Subsequently, control the contraction of the telescopic rod of the second electric cylinder 118. At this time, the core of the blind rivet 122 will be pulled out of the rivet body driven by the elastic three-jaw 128. At this time, the cable fixing piece 116 will be fixed on the ship's board, thereby fixing the cable on the ship's board (the hull). Subsequently, reverse the second driving motor 131 to reset the extrusion sleeve 129, so that the elastic three-jaw 128 expands, facilitating the insertion of the core of the next blind rivet 122.
