[0002] A landing net typically consists of a handle, a net ring, and a net bag. The net bag is fitted over the net ring, and the net ring is fixed to the handle. Fish are caught by holding the handle. A search reveals that Chinese patent CN212615791U discloses a button-type quick-release adapter, comprising a main body, an upper connector, and a lower connector. The upper connector has a T-shaped head and a plug-in portion, and the lower connector has an upper connecting portion and a lower connecting portion. The main body has a hollow structure with a through hole. The plug-in portion and the upper connecting portion are both located within the through hole, connecting the main body, the upper connector, and the lower connector into a single unit. The key feature is that a button hole is provided on the upper side of the main body, communicating with the through hole. A columnar button is provided within the button hole, and the end of the columnar button... A reset spring is provided. A connecting hole is provided at the position of the columnar button corresponding to the main body through hole. The connecting hole is a through hole with a diameter larger than that of the main body through hole. The insertion part is located both inside the main body through hole and the connecting hole. The insertion part has an annular locking groove along its circumference. The inner wall of the connecting hole has a locking part located within the locking groove. A retaining ring is also provided on the inner wall of the main body through hole, and a positioning sleeve is secured to the retaining ring. The top end of the positioning sleeve extends into the connecting hole. A positioning pin is also secured within the positioning sleeve. One end of the positioning pin is located within the positioning sleeve, and the other end of the positioning pin abuts against a second spring located within a second spring hole on the upper end face of the upper connecting part. The shortcomings of the above patents are: firstly, the structure of the above patents has many components, resulting in high usage costs and complex operation; secondly, the above patents control the engagement of the locking part and the locking groove through a columnar button and a reset spring, enabling the upper connector to connect and separate from the main body, achieving one-click quick assembly and disassembly of the anti-adaptor. However, when fishing, it is inevitable to come into contact with water, and the spring is prone to failure during long-term use. Contact with water will further corrode the spring, accelerating the aging process of the spring, leading to engagement failure, making it impossible to assemble or separate.

[0032] As attached Figure 1-3 When using it, the quick-connect device for the data collection net is installed on the data collection net. Specifically, Step 1: Install the net handle: The lower end of the connecting seat 1 is rotatably connected to the connecting sleeve 2 via the limiting protrusion 8, limiting groove 9 and / or annular groove 13, and annular limiting block 14. Then, the fixing sleeve 3 is inserted from top to bottom into the connecting channel 4 of the connecting seat 1. The limiting strip 5 is placed in the opening groove 6, which faces upward. The width of the opening groove 6 is greater than the width of the limiting strip 5, and the depth of the opening groove 6 is greater than the length of the limiting strip 5. Then, one end of the net handle is passed from bottom to top through the connecting sleeve 2 and into the fixing sleeve 3. The outer wall of the net handle abuts against the tensioning part of the fixing sleeve 3. The operator holds the connecting seat 1 with one hand and presses down on the fixing sleeve 3, keeping the fixing sleeve 3 stationary. Then, the other hand rotates the connecting sleeve 2, so that the connecting sleeve 2 and the fixing sleeve 3 are threadedly connected. This causes the fixing sleeve 3 to move from top to bottom towards the connecting sleeve 2. The upper part of the fixing sleeve 3 tightens, clamping the net handle, thus achieving a fixed connection between the net handle, connecting seat 1, fixing sleeve 3, and connecting sleeve 2. The second step is to install the net ring: The net ring has an opening. Put the net bag on through the opening, and then insert both ends of the opening into the insertion slots 11 of the two connecting rods 10 on both sides of the upper end of the connecting seat 1. The side wall of the insertion slot 11 has two connecting holes. The inner diameter of the connecting hole is smaller than the outer diameter of the screw head. The screw shank passes through the connecting hole and is fixedly connected to the net ring, fixing the net ring to the connecting rod 10. The screw connection makes it easy to replace the net ring and net bag. In this way, the net ring and net handle are fixedly connected through the connecting seat 1, connecting sleeve 2 and fixing sleeve 3, realizing the rapid assembly of the landing net. When it is necessary to remove the net handle, the operator holds the connecting seat 1 with one hand and rotates the connecting sleeve 2 in the opposite direction with the other hand. The fixing sleeve 3 moves upward as well. The upper part of the fixing sleeve 3 moves upward and separates from the connecting seat 1. The part between the adjacent opening slots of the fixing sleeve 3 opens upward and outward, no longer clamping the net handle, and the net handle can be pulled out to separate the net handle and the net ring. This utility model achieves the assembly and disassembly of the net handle by using the threaded connection between the fixing sleeve 3 and the connecting sleeve 2, which allows for the tightening or opening of the connecting sleeve 2. This makes it convenient to replace net handles of different lengths or net rings and net bags of different sizes as needed. This utility model has few parts, is simple and convenient to operate, has low operating costs, and features a threaded connection for easy assembly and disassembly, as well as a long service life.

[0033] This utility model, due to the above-mentioned structure, has the advantages of ingenious structure, few parts, simple operation, and smooth assembly and disassembly.
