[0031] The traction device 4 includes a rope collection drum 41, which is fixedly installed on the outside of the binding belt 1, and a storage chamber 401 and an equipment chamber 402 are provided inside the rope collection drum 41. A fixed tube 42 connected to the storage chamber 401 is fixedly installed outside the rope collection drum 41, and the fixed tube 42 can straighten the life rope 44 when the rope is collected. A rope collection rod 43 is rotatably connected to the middle of the storage chamber 401, and a life rope 44 is wound around the outside of the rope collection rod 43. The life rope 44 is away from the collection. One end of the rope rod 43 passes through the fixed tube 42 and is fixedly installed with a rubber plug 45. The rubber plug 45 can be plugged into the fixed tube 42, and the rubber belt plays a waterproof role. The end of the rubber plug 45 away from the life rope 44 is fixedly installed with an outer cover 46. A driving component 47 is installed inside the equipment cavity 402. The driving component 47 drives the rope collecting rod 43 to rotate, so that the life rope 44 is stored in the storage cavity 401 and wrapped around the surface of the rope collecting rod 43, so as to achieve the effect of arranging the life rope 44.

[0032] The driving assembly 47 includes a driving rod 471, a rectangular frame 473 and a rotating rod 476. The driving rod 471 is rotatably connected to the middle of the equipment cavity 402. One end of the driving rod 471 extends through and extends to the outside of the rope collecting drum 41 and is fixedly installed with a rotating disk 4710. The inner end of the driving rod 471 extends through and extends into the storage cavity 401 and is fixedly connected to the rope collecting rod 43. A ratchet 472 is fixedly installed on the outer surface of the driving rod 471. The rectangular frame 473 is fixedly installed on the top of the equipment cavity 402. A slide plate 475 is slidably connected to the middle of the rectangular frame 473. A first spring 474 is fixedly installed on the top of the slide plate 475. A sliding groove 4732 is provided in the middle of the bottom wall of the frame 473, and a tooth 478 is fixedly installed at the bottom of the slide plate 475. The bottom of the tooth 478 passes through the sliding groove 4732 and cooperates with the ratchet 472. The rotating rod 476 is rotatably installed in the upper part of the equipment cavity 402. A movable groove 4781 is provided in the middle of the tooth 478.

The outer surface of the rotating rod 476 is located on both sides of the tooth 478 and is fixedly installed with elliptical wheels 477. The elliptical wheel 477 is tightly attached to the bottom of the slide plate 475.

[0033] When it is necessary to collect the rope, turn knob 479, which drives rotating rod 476 to rotate, and rotating rod 476 drives elliptical wheel 477 to rotate. The proximal end of elliptical wheel 477 moves away from slide plate 475, and the distal end approaches slide plate 475, squeezing slide plate 475, and slide plate 475 moves upward, driving latch tooth 478 to move upward, away from ratchet 472, and rotating disk 4710 is turned. Rotating disk 4710 drives ratchet 472 to rotate, and ratchet 472 drives driving rod 471 to rotate, and driving rod 471 drives rope collecting rod 43 to rotate, and life rope 44 is wound around rope collecting rod 43, thereby completing the rope collecting work. After the rope is collected, turn knob 479 to make the proximal end of the elliptical disk approach slide plate 475, and slide plate 475 drives the elastic force of first spring 474 to move downward, thereby driving latch tooth 478 to move downward, and stopping the rotation of ratchet 472, thereby preventing the life rope 44 from being pulled out of the hand rope drum.

[0034] The connecting buckle 6 includes a connecting rope 61, which is fixedly mounted on the outside of the outer cover 46. A connecting head 62 is fixedly mounted on the end of the connecting rope 61, and a hook 63 is fixedly mounted on the bottom of the connecting head 62. The kayak can be hung on the handle of the kayak through the hook 63.

[0035] The bottom wall of the rectangular frame 473 is provided with a clearance groove 4731 matching the elliptical wheel 477 , and the clearance groove 4731 is used for making way when the elliptical wheel 477 rotates.

[0036] An arc groove corresponding to the elliptical wheel 477 is provided at the bottom of the slide plate 475. The arc groove can form a certain blocking and limiting effect when the distal end or proximal end of the elliptical wheel 477 enters the arc groove during rotation. When the knob 479 is loosened, the elliptical wheel 477 will not rotate spontaneously.

[0037] The lifesaving assembly 5 includes an equipment box 51, and a fixing plate 52 is fixedly installed on both the left and right ends of the equipment box 51. The fixing plate 52 is installed on the outside of the strap 1 by screws 518. The interior of the equipment box 51 is divided into two upper and lower parts, a first cavity 501 and a second cavity 502. An airbag 55 is installed in the second cavity 502. An opening 503 is opened at the outer end of the second cavity 502. A cover plate 54 is connected to the top of the opening 503 by a hinge. First sliding bars 56 are fixedly installed on both the left and right sides of the top of the first cavity 501. A limiting plate 57 is fixedly installed in the middle of the first sliding bar 56. An extrusion plate 59 is slidably connected to the rear sides of the outer surfaces of the two first sliding bars 56. A second spring 58 is sleeved on the outer surface of the first sliding bar 56. The second spring 58 is located between the limiting plate 57 and the extrusion plate 59. The plates 59 are provided between the plates 59, a high-pressure gas cylinder 53 is fixedly installed in the middle of the first cavity 501, a ejector pin 512 is fixedly installed in the middle of the front end of the extrusion plate 59, the ejector pin 512 is opposite to the high-pressure gas cylinder 53, and the high-pressure gas cylinder 53 is pierced by the ejector pin 512 to inflate the airbag 55, a gas supply pipe 511 is fixedly installed on the bottom wall of the first cavity 501, the gas supply pipe 511 extends through and extends into the second cavity 502 and is fixedly connected to the airbag 55, a pull rope 510 is fixedly installed on the upper side of the middle of the front end of the extrusion plate 59, the pull rope 510 passes through the front part of the equipment box 51 and is fixedly installed with an adapter 517, a sealing ring is provided between the pull rope 510 and the equipment box 51 to prevent the gas in the high-pressure gas cylinder 53 from leaking out from the gap between the pull rope 510 and the equipment box 51, and the adapter 517 is hinged with a pull ring 516.

[0038] When a person falls into the water, the pull ring 516 is pulled, and the pull ring 516 pulls the pull rope 510. The pull rope 510 drives the extrusion plate 59 to slide on the surface of the first slide plate 475, squeezes the second spring 58, drives the ejector pin 512 to approach the high-pressure gas cylinder 53, and the ejector pin 512 opens the high-pressure gas cylinder 53. The gas stored in the high-pressure gas cylinder 53 is discharged into the first cavity 501 and then transported from the gas pipe 511 to the airbag 55, and the airbag 55 is inflated, so that the user can float up and avoid drowning.

[0039] A second sliding rod 513 is fixedly installed at the lower portion of the inner wall. The second sliding rod 513 penetrates the extrusion plate 59 and is slidably connected thereto, so that the extrusion plate 59 can slide more stably in the first cavity 501 .

[0040] A side panel 514 is fixedly installed at the front end of the equipment box 51, and a movable opening 5140 is opened in the middle of the side panel 514, the pull ring 516 and the adapter 517 are both in the movable opening 5140, and a cloth curtain 515 is fixedly installed on the upper front end of the side panel 514, and a fur Velcro is fixedly installed on the inner surface of the cloth curtain 515, and a hook Velcro is fixedly installed on the front surface of the side panel 514. When the pull ring 516 is not in use, the pull ring 516 and the adapter 517 are both in the movable opening 5140, and then the pull ring 516 and the adapter 517 are covered by the Velcro to avoid accidental contact that causes the ejector pin 512 to puncture the high-pressure gas cylinder 53, thereby playing a role in preventing accidental contact.

[0041] A groove is provided on the right side of the bottom wall of the opening 503, and a first magnet sheet is fixedly installed on the left wall of the groove. A second magnet sheet is fixedly installed on the bottom of the cover plate 54. The first magnet sheet and the second magnet sheet attract each other, so that the cover plate 54 can cover the movable opening 5140 and store the folded airbag 55 in the second cavity 502. When the airbag 55 is inflated, the cover plate 54 is pushed open. When it is not popped out, the cover plate 54 and the opening 503 are adsorbed by the first magnet sheet and the second magnet sheet to avoid the cover plate 54 being lifted up during movement.

[0042] The working principle of the present invention is as follows: when in use, the rider fastens the belt around the waist through the connecting buckle 6, and then buckles it on the handle of the kayak through the connecting buckle 6, so as to prevent the rider from being pulled away from the kayak in a rapid current when falling into the water, resulting in the rider being unable to climb back to the kayak in time and causing the risk of drowning. At the same time, the traction device 4 provided can lengthen and retract the life rope 44. When not in use, the life rope 44 is stored in the rope retracting drum 41 to avoid being exposed to the outside for a long time, which may cause the life rope 44 to oxidize. After falling into the water, the life rope 44 can be lengthened to avoid being too close to the kayak and being pressed underwater after the kayak flips over. At the same time, when rescuing others, the life rope 44 can be lengthened. When the kayak is used, the connecting buckle 6 can be removed from the kayak, the life rope 44 can be extended, and thrown out to rescue people who fall into the water from a distance. It has multiple uses. At the same time, when people fall into the water, the pull ring 516 is pulled, the pull ring 516 pulls the pull rope 510, and the pull rope 510 drives the extrusion plate 59 to slide on the surface of the first slide plate 475, squeezes the second spring 58, and drives the ejector pin 512 to approach the high-pressure gas cylinder 53. The ejector pin 512 opens the high-pressure gas cylinder 53, and the gas stored in the high-pressure gas cylinder 53 is discharged into the first cavity 501 and then transported from the gas pipe 511 to the air bag 55, and the air bag 55 is inflated, so that the user can float and avoid drowning.
