[0022] Please refer to Figure 1 , Figure 4 , the limiting mechanism 9 includes a connecting shaft 91. The right end of the rotating shaft 12 is fixedly connected with the connecting shaft 91. The connecting shaft 91 is rotatably connected to the fixing plate 10. The outer side of the connecting shaft 91 is rotatably sleeved with a fixing seat 93.

[0023] The specific implementation process of the present utility model is as follows: When in use, when it is necessary to transfer eels, the output end of the first motor 11 drives the rotating shaft 12 and the winding roller 7 to rotate. The winding roller 7 lowers the steel wire rope 6, and the steel wire rope 6 drives the connecting ring 5 and the hanging scale 4 to move, so that the fish-carrying frame 2 can be lowered. When the fish-carrying frame 2 moves down to the bottom, it will contact the contact switch 81. At this time, the second motor 83 is started, and the output end of the second motor 83 drives the screw rod 84 to rotate, causing the side plate 85 to perform a threaded movement. The side plate 85 will slide along the guide rod 86, and the side plate 85 moves up and opens, facilitating the input of eels. After the eels are input, the first motor 11 rotates in reverse to make the fish-carrying frame 2 move up, and the fish-carrying frame 2 is separated from the contact switch 81. At this time, controlling the second motor 83 to rotate in reverse will re-close the side plate 85, which is convenient for the transfer and use of eels.

[0024] During the rotation of the winding roller 7, the winding roller 7 drives the connecting shaft 91 to rotate. The connecting shaft 91 drives the rotating block 92 to rotate along the fixed seat 93. The rotating block 92 and the ball 95 have relative sliding. The groove 94 of the rotating block 92 will squeeze and push the ball 95, causing the ball 95 to move in the vertical direction. The ball 95 drives the sliding seat 96 to slide along the fixed rod 97. The sliding seat 96 squeezes the spring 98, which can separate the groove 94 from the ball 95. When the first motor 11 stops working, under the elastic action of the spring 98, the ball 95 will reset and insert into the groove 94 at another position. During the rotation process, through the cooperation of the groove 94, the ball 95 and the spring 98, when the winding roller 7 is stationary, the ball 95 can be inserted into the groove 94 to limit the winding roller 7, which can prevent the fish-carrying frame 2 from falling due to the failure of the first motor 11 during the lifting process.
