In this embodiment, a telescopic portion is disposed between the two toggle pieces 32, the telescopic portion includes a main body 31, the main body 31 is horizontally slidably connected to the storage portion, a sliding slot is formed in the main body 31, two sides of the sliding slot are horizontally slidably connected to a telescopic shaft 311, one end of the telescopic shaft 311 is fixedly connected to a push plate 313, a second spring 312 is sleeved on the telescopic shaft 311, one end of the second spring 312 is fixedly connected to the main body 31, the other end of the second spring 312 is fixedly connected to the telescopic shaft 311, a limiting member located in the sliding slot is disposed between the two telescopic shafts 311, the limiting member is a limiting shaft 314, two ends of the limiting shaft 314 are both provided with conical protrusions, an elastic layer made of a rubber material is fixedly connected to the protrusions, a second permanent magnet is fixedly connected to the elastic layer, one end of the telescopic shaft 311, far away from the push plate 313, is provided with a conical limiting slot, and two sides of the sliding slot are both fixedly connected to a limiting block 315 for limiting the limiting shaft 314.

In this embodiment, the transverse shaft includes a main shaft 25 and a secondary shaft 27, the main shaft 25 is hollow, the secondary shaft 27 is located in the main shaft 25, the secondary shaft 27 is horizontally connected with the main shaft 25 in a sliding manner, a first spring 26 is arranged between the secondary shaft 27 and the main shaft 25, one end of the main shaft 25 is fixedly connected to the support ring 12, and one end of the secondary shaft 27 far away from the main shaft 25 is fixedly connected to the support ring 12. The two sides of the main shaft 25 and the auxiliary shaft 27 far away from one end of the longitudinal shaft 22 are fixedly connected with first permanent magnets 28.

In this embodiment, the connection portion 33 is fixedly connected with the pulling portion 23, the pulling portion 23 is fixedly connected with a plurality of pulling rings 24, the pulling rings 24 are fixedly connected with air pipes, the air pipes are communicated with the main shaft 25, the air pipes are communicated with a negative pressure pump, and the negative pressure pump and the air pipes form an air path system.

The limiting shaft 314 is fixedly connected with a pull rope 21, and one end of the pull rope 21 is fixedly connected to the auxiliary shaft 27.

The specific implementation process is as follows:

initially, the auxiliary shaft 27 is extended into the main shaft 25 and compresses the first spring 26, and the first permanent magnet 28 is attracted to the main shaft 25, so that the main shaft 25 and the auxiliary shaft 27 bring the support ring 12 to be contracted toward the longitudinal axis 22, and the upper opening of the fishing net part 11 is closed as much as possible.

After the fishing net part 11 is completely gathered, the fishing net part 11 and the support ring 12 are thrown into the water, and at this time, aquatic products (such as fish) do not enter the fishing net part 11 through the support ring 12. When the water reaches a preset position (such as the water depth or the water depth of a certain fish life), a certain amount of air is sent to the main shaft 25 through the air pump and the air pipe, the air enters the main shaft 25, the air pressure is matched with the elastic force of the first spring 26 to overcome the adsorption force of the first permanent magnet 28, and then the first spring 26 pushes the main shaft 25 and the auxiliary shaft 27 to separate, so that the support ring 12 is opened.

In the process, the fishing net part 11 and the support ring 12 are gradually moved upwards, the support ring 12 and the fishing net part 11 are pulled to move upwards through the air pipe, the pulling ring 24 and the pulling part 23, and the fishes can enter the fishing net part 11 to achieve the aim of fishing.

Of course, in this process, countershaft 27 can drive stay cord 21, stay cord 21 is with the spacing axle 314 of pulling, the second permanent magnet of spacing axle 314 breaks away from with telescopic shaft 311 (certain deformation can take place for the elastic layer, thereby reduce the hindrance of conical recess), offset until spacing axle 314 and stopper 315, under the effect of second spring 312, telescopic shaft 311 can promote stirring piece 32 (overcome the resistance of stirring piece 32 with the portion of accomodating), stirring piece 32 can drive the screen cloth and cover gradually in support ring 12 (be fan-shaped cover in support ring 12), until stirring piece 32 and first permanent magnet 28 adsorb, make the screen cloth seal support ring 12 basically, can reduce the great fish of size and run out (in order to improve fishing efficiency), can let the less fry of size run out. Compared with the prior fishing net direct binding, the fishing net binding machine can reduce the probability of the fishes with larger sizes in the fishing net binding process, and can not close most of the seedlings in the fishing net.

In this embodiment, the present invention is suitable for temporarily catching aquatic products having a small size or a small number, and is easily separated from the support ring 12 due to the limited resistance of the first permanent magnet 28, or is suitable for a fish tank or the like.
