Description

Technical Field

[0001] This utility model relates to the field of egg collection clip devices, specifically an adjustable and visual egg collection clip device for salmon and trout. Background Technology

[0002] The incubation process of fertilized eggs of large, economically important, cold-water fish such as salmon and trout is characterized by low water temperature, flowing water incubation, and a long incubation period, requiring incubation at a water temperature of 4-10℃ for 20-30 days. During incubation, unfertilized, damaged, or dead eggs are highly susceptible to water mold infection, and dead or damaged eggs must be removed as soon as possible to minimize their impact on healthy eggs and the chance of infection. Currently, there is no good method for efficiently removing damaged eggs, and manual collection is still required. However, the tools used for collection are mostly large tweezers and bamboo chopsticks, which are not only difficult to grasp and easily damage healthy fish eggs, but also have poor visibility due to water depth and light. Furthermore, the low water temperature limits the dexterity of the egg collector, making it difficult to accurately pick out damaged eggs. Therefore, this application proposes an adjustable and visual egg collection device for salmon and trout. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable and visual egg-collecting clip device for salmon and trout, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable visual egg-collecting clamp device for salmon and trout, comprising a clamp body, wherein movable rods are nested at the bottom ends of the clamp arms of the clamp body, and an egg-collecting ring is fixedly installed at the bottom end of each movable rod; finger sleeves are fixedly installed on both sides of the clamp arms of the clamp body, and each clamp arm of the clamp body is fixedly connected to each movable rod through a limiting component; the two clamp arms of the clamp body are elastically connected at their respective ends close to each other through a first spring; a light is fixedly installed at one end of the clamp handle of the clamp body; and a magnifying glass is fixedly installed on the side wall of one of the movable rods.

[0005] Preferably, each of the movable rods has a groove on one side, and each limiting component includes a limiting protrusion that is slidably connected to the corresponding movable rod groove.

[0006] Preferably, the bottom end of each limiting protrusion is fixedly connected to one end of the second spring, and the other end of each second spring is fixedly connected to one end of the groove inner wall of the movable rod.

[0007] Preferably, the clamp arm of the clamp body has a receiving groove on the side near the movable rod that matches the shape of the outer side of the movable rod, and a number of limiting holes that match the shape of the limiting protrusions are opened through the outer side of the clamp arm of the clamp body.

[0008] Preferably, the end of each limiting protrusion away from the movable rod is configured as an arc-shaped structure.

[0009] Preferably, the magnifying glass is distributed at an angle along one side of the movable rod.

[0010] Compared with the prior art, the advantages of this utility model are as follows:

[0011] This invention adjusts the length of each movable rod according to the water depth, allowing each rod to slide within the receiving groove of the clamping arm of the clamp body. Each limiting protrusion is pressed into the receiving groove of the clamping arm, enabling the movable rod to slide within the groove. Simultaneously, under the elastic force of the second spring, when the limiting protrusion aligns with the corresponding limiting hole, the movable rod is fixed by the limiting protrusion and the limiting hole. The operator inserts their right thumb and forefinger into the corresponding finger sleeves to retrieve the device, inserts the egg-collecting ring at the bottom of the movable rod underwater, and, under the illumination of the light, selects the bad eggs to be picked up using a magnifying glass. The operator then uses their right thumb and forefinger to clamp and pick up the bad eggs. The magnifying glass facilitates the operator's observation of the bad eggs. Attached Figure Description
