[0029] A rice field small lobster fishing device, as shown in Figure 1 and Figure 2 , comprising:

[0030] The cage body 10 and the end head 11 can slide along the radial direction of the cage body 10. The end head 11 has an opening for the lobster to enter the cage body 10. The end head 11 forms a square funnel structure. The smaller opening of the end head 11 extends into the cavity of the cage body 10. Through the funnel structure of the end head 11, the smaller opening is located in the cavity of the cage body 10. The lobster can enter the cage body 10 from the larger opening of the end head 11, but it needs to go out from the smaller opening of the end head 11, which will hinder the lobster and trap it in the cage body 10, achieving the fishing of the lobster.

[0031] The cage body 10 forms an open-ended square tube, the same end head 11 is arranged at both ends of the cage body 10, and a through hole for ventilation is formed in the side wall of the cage body 10. The through hole can be a circular hole, which can ensure that the lobsters in the cage body 10 will not die of oxygen deficiency and ensure the activity of the lobsters after being caught. The through hole can also be a rectangular slot radially formed along the cage body 10. Through the rectangular through hole, when the lobsters are poured out of the cage body 10, the rectangular slot-shaped through hole will not cause the pincers of the lobster to be stuck in the through hole, ensuring the integrity of the lobster when pouring out of the cage body 10, avoiding the broken legs of the lobster affecting the appearance, and the through hole shown in the figure is circular. The square through hole is not shown.

[0032] As shown in Figure 1 , Figure 3 and Figure 4 , the guide structure is arranged on the inner wall of the cage body 10 for adjusting the position of the end head 11. The guide structure includes a guide rod 12, a sliding rod 13 and a locking screw 14. The guide rod 12 is fixedly installed on the cage body 10. The sliding rod 13 is slidably connected with the guide rod 12. The end head 11 is fixedly connected with the sliding rod 13. The locking screw 14 is threadedly connected with the guide rod 12 and locks the sliding rod 13. The guide rod 12 forms a square tube. The sliding rod 13 is matched with the guide rod 12. The sliding rod 13 is slidably arranged in the cavity of the guide rod 12. The end of the sliding rod 13 is fixedly connected with the end head 11. The top of the guide rod 12 is provided with a threaded hole. The locking screw 14 is connected with the threaded hole. The end of the locking screw 14 can abut against the top surface of the sliding rod 13 to limit the sliding rod 13. The top of the cage body 10 is provided with a circular hole. The locking screw 14 extends to the outside through the circular hole.

[0033] By arranging two pullable movable end heads 11 at both ends of the cage body 10, when the lobsters caught in the cage body 10 are poured out, one of the locking screws 14 can be loosened. The end head 11 drives the sliding rod 13 to slide in the cavity of the guide rod 12, and then the smaller port of the end head 11 extends out of the cage body 10 and forms a gap with the port of the cage body 10. The cage body 10 can be stood up to discharge the lobsters. Compared with the prior art, the present scheme can quickly pour out the lobsters and is more convenient to operate. When the cage body 10 is put into the paddy field for catching, the end head 11 abuts against the end face of the cage body 10. The end head 11 blocks the port of the cage body 10. The position of the sliding rod 13 can be fixed by tightening the locking screw 14.

[0034] By arranging two movable end heads 11 at both ends of the cage body 10, two guide rods 12, sliding rods 13 and locking screws 14 are arranged on the inner top surface of the cage body 10 for locking the end heads 11 respectively. The design of discharging lobsters from both ends is more convenient to use. The inclined surface of the funnel-shaped end head 11 can catch the falling lobsters in the cage body 10 when the lobsters in the cage body 10 are poured out, realizing the guidance and deceleration of the lobsters, avoiding the lobsters falling directly into the collecting container from the cage body 10 to cause injury, and ensuring the integrity and activity of the lobsters after being poured out.
