Because the top ends of the two rotating blocks 12 are rotatably connected to the U-shaped block 6, the U-shaped block 6 is connected to the U-shaped block 6. The inner wall, so when the U-shaped block 6 is pressed down, the U-shaped block 6 will drive the rotating block 12 to rotate around the fixed axis 11 and pull the clamp 10 upward to squeeze the spring 2 9 to deform, so as to realize the retraction of the clamp 10 into the movable groove 5 to disengage from the clamping hole 3 of the extension rod 2. The bottom end of the fishing net 16 is fixedly connected to the connecting rod assembly 22, and the connecting rod assembly 22 connects the two sides of the bottom net opening of the fishing net 16. The opening and closing of the bottom net opening of the fishing net 16 is realized by the connection of the two rods and the cooperation of the threaded cover.

[0037] refer to Figure 3 , Figure 4 The outside of the steel ring 14 is provided with an adjustment component, which includes a plurality of notched grooves 17, a sleeve block 18, a groove 19, a rotating shaft 20 and a gear 21. The outside of the steel ring 14 is provided with a plurality of notched grooves 17, and the notched grooves 17 are provided at the outer edge of the steel ring 14. The outside of the steel ring 14 is fixedly connected with a sleeve block 18, and the sleeve block 18 is fixedly connected to the head at one end of the outer side of the steel ring 14. The inside of the sleeve block 18 is provided with a groove 19, and the middle part of the top of the sleeve block 18 is rotatably connected with a rotating shaft 20, and the rotating shaft 20 is A gear 21 is fixedly connected to the outer bottom end, and the outer part of the gear 21 is slidably connected to the inner wall of the groove 19. The outer teeth of the gear 21 are engaged with the inner wall of the notch groove 17. The rotating shaft 20 that limits the rotation of the top of the sleeve block 18 fixed on the rear side of the rotating steel ring 14 is rotated, and the rotating shaft 20 is rotated to drive the fixed gear 21 to fit closely with the inner wall of the groove 19 and engage with the notch groove 17 opened on the outer edge of the steel ring 14, pushing the inner end of the steel ring 14 to slide on the inner wall of the groove 19 of the sleeve block 18, thereby gradually reducing the ring opening of the steel ring 14.

[0038] Working principle: When the operator uses it, if the length of the hand-held rod 1 needs to be lengthened and adjusted, the operator can continuously press the U-shaped block 6 to slide the front and rear sides of the U-shaped block 6 and then squeeze the spring 1 8 on the inner wall of the movable groove 5, so that the U-shaped block 6 can remain straight downward. Because the top ends of the two rotating blocks 12 are rotatably connected to the inner wall of the U-shaped block 6, when the U-shaped block 6 is pressed down, the U-shaped block 6 will drive the rotating block 12 to rotate around the fixed axis 11 and pull the clamp 10 upward to squeeze the spring 2 9 to deform, so as to achieve the retraction of the clamp 10 into the movable groove 5 and disengage from the clamp hole 3 of the extension rod 2. At this time, the clamp 10 can be pulled out. The extension rod 2 slides inside the hand-held rod 1. When the extension rod 2 is pulled to a suitable length, the U-shaped block 6 can be loosened to allow the spring 1 8 to support the inner wall of the movable groove 5 and drive the U-shaped block 6 to reset through the connection with the vertical block 7. The clamp 10 is driven downward by the spring 2 9 and the rotating block 12 to engage with the clamping hole 3 at different positions at the bottom of the clamp 10 at this time, thereby fixing the extended length of the extension rod 2. The operator can adjust the length of the rod according to the specific fishing depth. At different depths or in different water environments, the hand rod can be easily extended or shortened to ensure that the fish catcher can reach the target depth.

[0039] When the operator needs to adjust the opening of the steel ring 14 in order to catch different target objects, he can hold the steel ring 14 and limit the rotation of the rotating shaft 20 on the top of the sleeve block 18 fixed on the rear side of the rotating steel ring 14, so that the rotating shaft 20 rotates to drive the fixed gear 21 to fit closely with the inner wall of the groove 19 and engage with the notch groove 17 opened on the outer edge of the steel ring 14 to push the inner end of the steel ring 14 to slide on the inner wall of the groove 19 of the sleeve block 18, thereby gradually reducing the opening of the steel ring 14, and finally adjust the position of the ring 15 fixed to the fishing net 16.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
