[0016] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0017] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0018] The following is combined Figures 1-4 The present invention will be described in detail below. For ease of description, the directions referred to below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The directions of front, back, left, right, up, and down in the view are consistent. Figure 1 This is a front view of the device of the present invention. Figure 1 The directions shown are consistent with the front-to-back, left-to-right, up-down directions of the device of the present invention when viewed from the front.

[0019] Please seeFigures 1-4 In one embodiment, the application provides a fisher suitable for a breeding barrel, which comprises a reference rod 12, a through cavity 19 is arranged in the reference rod 12, a through sliding rod 13 is slidably arranged in the through cavity 19, a slidable center ring 10 is arranged on the outside of the reference rod 12, the inside wall of the center ring 10 is fixedly connected with the two end faces of the through sliding rod 13, eight supports 11 are uniformly fixed on the outside of the center ring 10, a fishing net 23 is fixedly installed between the adjacent supports 11, a fishing grab rod 15 is rotatably installed on each support 11, a base 21 is fixedly arranged on the wall of the fishing grab rod 15, a disc 18 is fixedly installed on the lower end of the reference rod 12, eight grooves 22 are arranged on the side of the disc 18 close to the reference rod 12, each groove 22 corresponds to the fishing grab rod 15, a support rod 20 is rotatably installed on the cavity wall of each groove 22 through a rotating shaft, the length of the support rod 20 is the radius of the breeding barrel, and the other end of the support rod 20 is hingedly connected with the base 21 on the corresponding fishing grab rod 15.

[0020] In addition, in one embodiment, a roller groove 16 is arranged on the end of each fishing grab rod 15 opposite to the connection with the support 11, and a roller 17 is rotatably installed on the cavity wall of the roller groove 16.

[0021] In addition, in one embodiment, a power element 14 is fixedly installed on the cavity wall of the through cavity 19, and the output end of the power element 14 is fixedly connected with the through sliding rod 13. The power element 14 can be an extensible rod or a hydraulic rod.

[0022] In addition, in one embodiment, a linkage hook 24 is arranged on the top end of the reference rod 12, and the linkage hook 24 is connected with a hoisting device to drive the whole to move.

[0023] In specific implementation, the whole is placed into the breeding barrel through the linkage hook 24 of the hoisting device, and slowly sinks into the breeding barrel through the gravity of the structure. When the lower end of each fishing grab rod 15 contacts the bottom of the breeding barrel, the power element 14 is started, the power element 14 drives the through sliding rod 13 to move downward in the through cavity 19, and then the through sliding rod 13 drives the center ring 10 and the support 11 to move downward, so that the eight fishing grab rods 15 rotate around the connection to the four directions under the action of the support rod 20, and the fishing net 23 between the fishing grab rods 15 is slowly opened. While the fishing grab rods 15 are opened, the whole still slowly sinks, so that the rollers 17 can be in close contact with the inner wall of the breeding barrel, to prevent fish from escaping through the gap and entering the lower part of the fishing net. The present application has the advantages of simple structure, simple replacement of parts, convenient operation, high fish catching rate for the shape and characteristics of the breeding barrel, and the like.

[0024] The above merely describes the specific implementation of the application, but the protection scope of the application is not limited thereto, any change or replacement without creative labor should be covered in the protection scope of the application. Therefore, the protection scope of the application should be limited by the protection scope defined in the claims.
