[0002] Modern fishing nets are mainly made of polyethylene, nylon and other raw materials. They have a longer service life and higher fishing efficiency, and are classified by different usage methods. For example, the cast net used in traditional fishing, the trawl net powered by boats, and the gill net with different mesh sizes to trap fish. These nets are made of meshes of different sizes and wires of different materials for different fishing targets.

[0003] During the use of fishing nets, the pulling force of human power or fishing boats, as well as the struggling and tearing force of fish in the net will be exerted on the fishing nets. Therefore, fishing nets have high requirements for resisting pulling forces. During the production process of fishing nets, sampling tests on the tensile strength of fishing nets are also required.

Corresponding to each other, multiple sliders 9 are slidably connected in the slide groove 8, and fixed plates 10 are arranged outside the opposite sides of the sliders 9. A tension sensor 11 is installed between the fixed plate 10 and the sliders 9. A buckle 12 is connected to the fixed plate 10, and a notch is arranged on one side of the buckle 12. A stopper 13 adapted thereto is arranged in the notch. The tail end of the stopper 13 is hinged in the notch of the buckle 12 through a pin shaft, and the tail end of the stopper 13 is also provided with a notch. A torsion spring 14 is sleeved at the notch of the tail end of the stopper 13 corresponding to the pin shaft. The two ends of the torsion spring 14 are respectively against the inner wall of the notch of the buckle 12 and the stopper 13. The top of the stopper 13 and the opposite side of the buckle 12 are provided with grooves, which correspond and match. The buckle 12 forms a limiting effect on the stopper 13 through the setting of the groove, so as to prevent the stopper 13 from popping out of the notch on the buckle 12. A fishing net is hooked between the buckles 12.

[0025] The lead screw 6 is driven by the motor 23, and the movable beam 5 is driven to slide along the guide rod 4 through the cooperation of the thread sleeve 7, so that the two slide grooves 8 are moved away from each other, thereby achieving tensioning. During tensioning, the tension sensor 11 monitors the tensioning force, thereby facilitating the tensioning force control.

[0026] The notch on the buckle 12 makes it convenient to hook the edge of the fishing net on the buckle 12, and the torsion spring 14 rebounds the stopper 13 to close the notch, so that the fishing net is directly confined in the buckle 12, thereby effectively preventing the fishing net from falling off.

[0027] A threaded head 15 is fixedly connected to the bottom of the ring buckle 12 . The threaded head 15 is inserted into the fixing plate 10 and is threadedly connected to the fixing plate 10 . The fixing plate 10 is provided with a threaded hole for the threaded head 15 to be threadedly connected.

[0028] The ring buckle 12 is threadedly connected to the threaded hole on the fixing plate 10 through the threaded head 15, so that the ring buckle 12 can be easily replaced.

[0029] A long slot is formed on the side wall of the slide 8 corresponding to the slider 9, and a threaded column 16 is fixedly connected to the slider 9. One end of the threaded column 16 passes through the slide 8 through the long slot and is threadedly connected to a hand nut 17.

The slider 9 slides in the slide groove 8 and is tightened by hand-tightening the nut 17 in cooperation with the threaded column 16 to achieve extrusion and fixation, thereby adapting to fishing nets of different mesh sizes. The adjusting seat 21 slides on the adjusting column 18 to control the height of the column 2 and at the same time cooperates with the locking bolt 22 to penetrate the corresponding socket 24 for locking and fixing, so that the device can be quickly adjusted to adapt to the size of the fishing net. At this time, the stopper 13 is squeezed to open the gap on the ring buckle 12, and the edge of the fishing net is hooked on the ring buckle 12, and then the stopper 13 is loosened. The stopper 13 is reset on the left and right lower parts of the torsion spring 14 to cover the gap, so that the fishing net is confined in the ring buckle 12. At this time, the motor 23 is started, and the motor 23 drives the screw rod 6, which drives the movable beam 5 to slide along the guide rod 4 through the cooperation of the silk sleeve 7, so that the two slide grooves 8 are away from each other, thereby achieving tensioning. During tensioning, the tension sensor 11 monitors the tensioning force adjustment, thereby facilitating the tensioning force control.

[0038] When the buckle 12 is damaged after long-term use, it can be unscrewed from the fixing plate 10 with the cooperation of the thread head 15, so as to facilitate the replacement of the buckle 12.
