Offer the hole 11 that supplies flexibility to stretch through in fishing rod 1, flexible rope 3 runs through this fishing rod 1 to stretch out from fishing rod 1 upper end, thereby can pull flexible rope 3 in the upper end of fishing rod 1, conveniently drag control to fishing hook 2, be convenient for carry out the salvage operation to fishing hook 2.
In order to improve the stability of the salvaging hook 2 for hanging equipment, the bending radian of the salvaging hook 2 can be limited, and the radian of the salvaging hook 2 is preferably 180-270 degrees; under the condition of larger radian, the fishing hook can form good blocking limiting effect at the two sides of the fishing hook 2, the limiting stability of the fishing hook 2 can be improved, and the falling-off condition in the fishing hanging process is avoided. Because the radian is large, the fishing hook 2 in a general fixed state cannot be directly hung at the hanging position of equipment to be fished; through the form of sliding in this, can be under the state of straightening, with salvaging hook 2 and hanging position alignment earlier, then can pull salvaging hook 2 through pulling flexible rope 3, crooked into the hook, can realize the light dress of hanging of carrier under water.
The flexible hook type fisher also comprises a sleeve 4, wherein the sleeve 4 is sleeved outside the salvage rod 1 and can be adjusted along the length direction of the salvage hook 2, and can be sleeved outside the salvage hook 2; can realize the suit protection to flexible salvage hook 2 through sleeve 4 to can form stable state after the cover is established, be convenient for do benefit to the dress calibration action of hanging of salvage hook 2 after the suit.
The inner diameter of the sleeve 4 is larger than that of the chain link 21, a limiting convex ring 41 is arranged on the inner periphery of one end, far away from the salvaging hook 2, of the sleeve 4, a limiting stop I12 is arranged on the outer periphery of the lower end of the salvaging rod 1, a limiting stop II 13 is arranged on the outer periphery of the upper end of the salvaging rod, and the limiting stop I12 and the limiting stop II 13 are respectively used for propping and limiting with the limiting convex ring 41, so that the stroke of the sleeve 4 can be limited. When the sleeve 4 is adjusted upwards, the limiting convex ring 41 is propped against the limiting stop II 13 when the sleeve 4 is at the uppermost end, so that the position limiting is realized, and the sleeve 4 is prevented from falling off from the upper end; when the sleeve 4 is adjusted downwards, the limiting convex ring 41 of the sleeve 4 is in a position of the lowest end and is in pressing limit with the first limiting stop 12, so that position limiting can be realized, and the sleeve 4 is stably maintained at a position outside the flexible hook.
When the underwater carrier is recovered, after the calibration of the fisher and the hook of the underwater carrier is completed, an operator holds the salvage rod 1, and the adjusting sleeve 4 moves upwards along the salvage rod 1; at this time, the flexible salvage hook 2 leaks from the lower end of the sleeve 4, and the operator pulls the flexible rope 3 to change the salvage hook 2 from a straight state to a bent state, so as to control the underwater carrier, thereby completing the underwater carrier recovery.
In order to maintain the stability of the sleeve 4, a through groove 101 can be formed in the periphery of the fishing rod 1, and the through groove 101 can be clamped with the elastic piece 102 of the inner side 201 of the sleeve 4, so that the sleeve 4 can be positioned when the sleeve 4 is adjusted to the uppermost position; specifically, two through grooves 101 are formed in the outer side of the fishing rod 1 and close to the second limit stop 13, an elastic sheet 102 is connected to the lower side of the through grooves 101, the upper end of the elastic sheet 102 is obliquely bent towards the inner cavity of the fishing rod 1, and the elastic sheet 102 can elastically clamp the flexible rope 3 in the fishing rod 1. An elastic clamping block 105 is arranged on one side, close to the second limit stop 13, of the inner peripheral wall of the sleeve 4, and when the elastic clamping block 105 is embedded into the through groove 101, the elastic clamping block can be elastically clamped into the through groove 101 and pushes the elastic sheet 102 to elastically squeeze the flexible rope 3, so that stable clamping of the flexible rope 3 can be maintained; when the second limit stop 13 at the upper end of the sleeve 4 abuts against the limit convex ring 41, the elastic clamping block 105 is just clamped into the through groove 101.
An inward protruding arc-shaped part 103 is formed at the upper end of the elastic sheet 102, and a friction pad 104 for pressing and friction with the flexible rope 3 is fixed at the inner side 201 of the arc-shaped part 103, and friction is generated between the friction pad 104 and the flexible rope 3. When the flexible rope 3 stretches upwards, the flexible rope 3 drives the elastic piece 102 to bend outwards 202 to a certain extent, so that the flexible rope 3 can be smoothly pulled up; when the flexible rope 3 moves downwards, mutual friction is generated between the flexible rope 3 and the friction pad 104, and the friction force drives the elastic sheet 102 to elastically deform downwards in an inclined way towards the inner side 201, so that a certain friction self-locking effect is generated between the flexible rope 3 and the friction pad 104. The elastic clamping block 105 also has certain elastic performance, and when the elastic clamping block 105 is clamped into the through groove 101, the elastic clamping block 105 can generate certain elastic clamping acting force inwards on the elastic sheet 102, so that the clamping stability between the elastic sheet 102 and the flexible rope 3 is kept.
