[0021] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation mode of the utility model will be described with reference to the drawings, but the protection scope of the utility model is not limited to the following description.

[0022] Referring to Figure 1 the drag hook for sea cucumber culture, which comprises a handheld part 1, a hook part 2 and a connecting part 3.

[0023] The handheld part 1 is the part directly contacting the hand of the user, and adopts a cylindrical shape in design, which can fit the palm and give the user a comfortable holding feeling. In order to cope with the potential risk of slipping in the humid culture environment, a rubber sleeve can be sleeved on the surface of the handheld part 1.

[0024] The hook part 2 is the core part of the drag hook for hooking the culture net, which is curved and has a sharp end 201. This design enables the hook part 2 to easily insert into the mesh of the culture net and be effectively hooked. When the hook part 2 is inserted into the culture net, the curvature can ensure that the hooking phenomenon does not occur during lifting the net, thereby ensuring the smooth operation.

[0025] The connecting part 3 connects the hand-held part 1 and the hook part 2 tightly, and is mainly made of a firm and durable material to ensure the stability and reliability of the connection. In terms of structure, it can be a metal rod connecting the hook part 2 and the hand-held part 1.

[0026] As a preferred embodiment, considering that the farming operation is carried out in the marine environment, in order to prevent the hook from being lost by accidentally falling into the sea, the present application is provided with a layer of foam sleeve 4 outside the connecting part 3. The foam sleeve 4 has good buoyancy characteristics. Once the hook falls into the water accidentally, the foam sleeve 4 can provide sufficient buoyancy to make the hook float on the sea surface, so that the farming personnel can salvage it in time, avoiding economic losses and inconvenience caused by tool loss.

[0027] As a preferred embodiment, considering that the farming personnel will be extremely tired after lifting the farming net and continuing to hold it for a long time to check and clean, the present application is provided with a fork 5 on the connecting part 3, which is arranged obliquely downward relative to the connecting part 3. When the farming net is successfully lifted, the farming personnel can place the fork 5 on the floating bridge. At this time, the fork 5 acts as a support point and shares part of the weight of the farming net, greatly reducing the burden on the hands of the farming personnel, allowing them to check and clean the farming net more easily and comfortably, and significantly improving the comfort and efficiency of the work.

[0028] As a preferred embodiment, referring to Figure 2 The relative distance between the fork 5 and the hook part 2 is adjustable. This design aims to meet the diverse needs of the operation, especially in changing the distance of the farming net being pulled up. In principle, the maximum depth position that the hook part 2 can reach when hooking the farming net is fixed. However, when the fork 5 is used as a support point to fix the farming net, changing the position of the fork 5 relative to the hook part 2 can change the distance of the farming net being pulled up. This adjustable design can make the hook better fit various complex and variable farming environments and operation scenarios, providing strong support for the efficient development of farming work.

[0029] As a preferred embodiment, referring to Figure 3As shown, the prongs 5 can be fixed with the connecting part 3 by using the threads 301, specifically, the prongs 5 are composed of two prongs 501 and a nut sleeve 502, the two prongs 501 and the nut sleeve 502 are welded and fixed, the matching threads 301 are arranged on the connecting part 3, the aquaculture personnel can adjust the relative distance between the prongs 5 and the hook part 2 by rotating the nut sleeve 502. In addition, in order to prevent the prongs 5 from rotating by itself due to external force during the operation, the locking nut 6 matched with the prongs 5 is specially arranged on the connecting part 3. When the aquaculture personnel adjusts the prongs 5 to the appropriate position, the locking nut 6 is tightened, so that the prongs 5 can be kept in the set position, and stable and reliable support for the aquaculture operation is provided, and the convenience and stability of the hook during the actual use are further improved.

[0030] The above only discloses the preferred embodiments of the present application, and of course cannot limit the scope of the present application, therefore, equivalent changes made according to the claims of the present application still belong to the scope covered by the present application.
