[0070] Working principle: This application is an innovative device designed for long-distance casting and full-water layer fishing, suitable for raft fishing, shore fishing and other scenarios. Its core advantages are: long-distance casting: lightweight design, easy to throw to a remote water area; full-automatic capture: no manual intervention, fish bite hook automatically triggers capture action; full water layer coverage: through the "sky and earth double fishing" system to catch surface, middle and bottom fish; high safety: built-in unloading spring and double safety mechanism to prevent fish line breakage or accidental triggering.

[0071] The specific workflow is as follows:

[0072] S1, double hook fixing: the sky hook 81 and the ground hook 82 are adhered in the hidden hook semicircular groove 261 of the hidden hook block 26 by water-soluble adhesive, ensuring that the double hooks are not entangled with the fish hook line 8 during casting, and the bait bin 4 is filled with atomized bait, and the diffusion rate is controlled through the bait atomization holes 121, 122, 123 and 124 of the upper cover cap 1.

[0073] S2, water release: after the device enters the water, the water flow dissolves the water-soluble adhesive, the sky hook 81 and the ground hook 82 are separated from the hidden hook block 26, the fish hook line 8 freely stretches along the movable connection point of the automatic trip assembly 7, and the bait begins to atomize, forming a fish attracting area.

[0074] S3, sucking and testing: fish are attracted by bait and approach the device to suck atomized bait, and the fish mouth contacts the bait on the sky hook 81 or the ground hook 82, and the rubber delay safety sheet 81 filters the light touch signal of small fish to avoid accidental triggering.

[0075] S4, spitting bait triggers pain: if the fish spits bait after sucking, the hook tip slightly penetrates the fish mouth palate or inner wall due to inertia, causing pain, and the fish violently shakes its head due to pain, generating a lateral shaking force that is transmitted to the automatic trip assembly 7 through the fish hook line 8.

[0076] S5, trip start: the shaking force pulls the fish hook line 8, making the automatic safety pin 72 separate from the temporary clamping angle 73 of the U-shaped fixed frame 71, and the trigger condition is set to the shaking force exceeding the clamping threshold of the automatic safety pin 72, and the directional groove 312 guides the fish hook line 8 to slide along the preset path, ensuring stable triggering of the trip mechanism.

[0077] S6, spring rebounding and piercing fish: after the automatic safety pin 72 trips, the stainless steel spring 54 instantaneously rebounds, and the sky hook 81 or the ground hook 82 is pierced into the fish mouth through the fish hook line 8.

[0078] S7, double hook linkage: after the sky hook 81 or the ground hook 82 that triggers the fish piercing is pierced into the fish mouth, the other fish hook is retracted into the hidden hook semicircular groove 261 at the bottom of the lower cover cap 3 through the linkage of the fish hook line 8, preventing bottom hanging.

[0079] S8, shake off the force: fish after the pain of the hook, produce explosive pull, through the fish line 8 to the automatic unloading assembly 5, stainless steel spring 54 telescopic sliding in the hollow sleeve 22, the peak pull is converted into elastic potential energy buffer release, avoid the fish line break.

[0080] S9, travel limit protection: travel limit rope 56 limit the maximum length of the automatic unloading assembly 5, prevent spring 54 over deformation, sliding positioning pad 10 through the limiting ring 101 fixed assembly position, ensure the stability of the unloading process.

[0081] S10, line fishing: fish exhausted, through the external fishing line 6, fish hook line 8 along the directional groove 312 slide back to the initial position, the fish hook into the fish mouth from the fish mouth.

[0082] S11, device reset: re-fill bait bin 4, and use water soluble adhesive fixed double hook to the hidden hook block 26, manual reset automatic pin 72 to the clamping angle 73, ready for the next time.
