[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model comprises a cylinder, a lifting cylinder, a sliding rod, a shuttle head, a lifting plate, a connecting plate, and an insert rod. By moving the shuttle head upward, the sliding rod and the lifting plate move upward. The connecting plate allows the insert rod to disengage from the insertion hole. After the lifting cylinder is moved to the target height, the spring force of spring one causes the lifting plate to move downward and insert the insert rod into the corresponding height insertion hole, thus realizing the adjustment of the lifting cylinder height. The structure is simple and the operation is convenient, making the whole device suitable for threading fishing nets of different specifications.

[0012] 2. This utility model also incorporates a support frame, push rod, moving plate, cutter, clamping block, and spring. By manually pressing the push rod, the two moving plates on both sides move towards each other, and the cutter cuts the edge line, eliminating the need for workers to hold scissors. Furthermore, after the cutter has finished cutting, the clamping block can hold and fix the edge line, preventing it from detaching from the outside of the cylinder due to elastic stress after cutting. This reduces the workload of workers and improves their threading efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a fishing net edge-threading auxiliary device, including a cylinder 1, with two symmetrical limiting strips 2 welded and fixed inside the cylinder 1, a sliding connection between the inside of the cylinder 1 and a lifting cylinder 3, a limiting groove 4 opened on the outside of the lifting cylinder 3, a sliding connection between the inside of the lifting cylinder 3 and the outside of a sliding rod 5, the top of the sliding rod 5 welded and fixed to a shuttle head 6, the outer diameter of the shuttle head 6 being the same as the outer diameter of the lifting cylinder 3, the bottom of the sliding rod 5 welded and fixed to a lifting plate 7, the lifting plate 7 being hinged to one end of a connecting plate 8, and a sleeve on the outside of the sliding rod 5. A spring 9 is provided, located between the lifting cylinder 3 and the lifting plate 7. An insert rod 10 is installed inside the lifting cylinder 3, and an insertion hole 11 is opened inside the cylinder body 1. The outer side of the cylinder body 1 is welded and fixed to the support frame 12. The outer side of the support frame 12 is slidably connected to two symmetrical push rods 13. One end of the push rod 13 is welded and fixed to the moving plate 14. The side of the moving plate 14 is welded and fixed to the cutter 15, and the side of the moving plate 14 is welded and fixed to the clamping block 16. A second spring 17 is sleeved on the outer side of the push rod 13. A wire hole 18 is opened at the bottom of the support frame 12.

[0020] The limiting groove 4 is slidably connected to the outside of the limiting strip 2. The lifting cylinder 3 is slidably connected to the inside of the cylinder 1 through the limiting groove 4. A circular through hole is opened at the top of the lifting cylinder 3, and the lifting cylinder 3 is slidably connected to the outside of the sliding rod 5 through the circular through hole. The lifting movement of the lifting cylinder 3 is limited by the cooperation of the limiting strip 2 and the limiting groove 4, so as to prevent the lifting cylinder 3 from being inserted into the cylinder 1 or from being moved inside the cylinder 1. If the insertion rod 10 and the insertion hole 11 are not on the same vertical line, the insertion rod 10 will not be able to be inserted into the insertion hole 11 to connect and fix the cylinder 1 and the lifting cylinder 3.

[0021] The top of the slide rod 5 extends above the lifting cylinder 3 and is welded and fixed to the shuttle head 6. The top of the shuttle head 6 is a pointed tip. The bottom of the slide rod 5 extends into the lifting cylinder 3 and is welded and fixed to the lifting plate 7. The lifting plate 7 is hinged to one end of the connecting plate 8 through a hinge groove. The other end of the connecting plate 8 is hinged to the insertion rod 10. There are two connecting plates 8 and two insertion rods 10, which are symmetrically distributed on both sides of the lifting plate 7. Lifting the shuttle head 6 upwards causes the slide rod 5 and the lifting plate 7 to move upwards, thereby driving the connecting plate 8 to move the lifting plate 7 out of the insertion hole 11. The lifting cylinder 3 is adjusted to a suitable height through the inside of the cylinder 1. The lifting plate 7 is pushed downwards by the elastic force of the spring 9. The insertion rod 10 is pushed into the insertion hole 11 by the connecting plate 8, thereby connecting and fixing the cylinder 1 and the lifting cylinder 3, realizing the adjustment of the overall length.

[0022] The insertion holes 11 are evenly distributed in a linear array inside the cylinder 1. The insertion holes 11 are movably inserted into the insertion rod 10. The support frame 12 is a U-shaped plate, which is slidably connected to the outside of the push rod 13 through a circular through hole. The push rod 13 is a T-shaped rod, and there are two push rods 13, which are symmetrically distributed.

[0023] Working principle: When using the device, the operator lifts the shuttle head 6 upwards, causing the slide bar 5 and the lifting plate 7 to move upwards. This moves the connecting plate 8, causing the lifting plate 7 to move out of the insertion hole 11. The lifting cylinder 3 is adjusted to a suitable height inside the cylinder 1. The lifting plate 7 is then pushed downwards by the elastic force of the spring 9. The connecting plate 8 pushes the insertion rod 10 into the insertion hole 11, thus connecting and fixing the cylinder 1 and the lifting cylinder 3. This allows for adjustment of the overall length, making it easier for the operator to thread different fishing net edge lines. After the fishing net edge lines are threaded, the push rods 13 on both sides are pressed simultaneously, causing the moving plate 14 to move towards each other. The cutters 15 on both sides cut the edge lines, and the clamps 16 on both sides clamp and fix the cut edge lines to prevent them from detaching from the lifting cylinder 3 due to elastic contraction after cutting, thus reducing the difficulty of threading the lines multiple times.
