Further, the left and right sides of the lower end of the outer wall of the housing 300 are provided with integrally formed arc-shaped openings, so that the two pull rods 510 can be freely pulled downwards.
Further, when the second spring 940 is not compressed, the distance between the lower ends of the two curved hooks 930 is smaller than the width of the latch 980, so that the lower ends of the two curved hooks 930 can clamp the latch 980 under the action of the second spring 940.
In conclusion, the working process of the invention is as follows: when the trainer pulls the safety handle component 520 downwards, the pull rod 510 drives the first rotating rod 420 and the second rotating rod 440 to rotate downwards, at the same time, the first rotating rod 420 drives the first gear 410 to rotate, the first gear 410 drives the sliding block 320 engaged and connected with the first gear to slide upwards, when the sliding block 320 slides upwards, the sliding block 320 drives the middle block 530 to move upwards, so that the second extrusion block 680 slides upwards, the second extrusion block 680 slides upwards to drive the third rack 660 to slide upwards, so that the third rack 660 drives the second gear 610 engaged and connected with the third rack to rotate, at the same time, the second gear 610 drives the second rack 620 on the left side to slide downwards, so that the second rack 620 and the third rack 660 move towards each other and extrude the first spring 690, the arm strength of the trainer is exercised by overcoming the resistance of the first extrusion spring 690, when the second rack 620 slides downwards, the top plate 630 and the right sliding plate 640 can be driven to simultaneously slide the top plate 630 downwards, the rotating rod three 710 and the rotating rod four 720 can be driven to rotate, the rotating rod three 710, the rotating rod four 720 and the top plate 630 form a slider-crank mechanism, so that when the top plate 630 slides up and down, the rotating rod four 720 can be driven to do circular motion, power is generated for the micro-generator 810, meanwhile, when the extrusion block two 680 moves up and down, the connecting rod one 911 can be simultaneously driven to move up and down, when the connecting rod one 911 drives the bending hooks 930 to slide downwards, the two bending hooks 930 can clamp the connecting rod two 970 under the action of the spring two 940, and when the connecting rod one 911 drives the bending hooks 930 to slide upwards, the upper ends of the two bending hooks 930 extrude the trapezoidal openings 901, the spring two 940 are compressed, the lower ends of the two bending hooks 930 open the clamping block 980 and the bending hooks 930, meanwhile, the second spring 940 is reset and is restored to the original length, so that a trainer can increase the received resistance through the balancing weight 960 when pulling the pull rod 510 downwards, the training difficulty and the training effect are improved, and meanwhile, when the two bent hooks 930 move to the uppermost end, and the clamping block 980 is separated from the bent hooks 930, the resistance received by the trainer can be reduced, and the user is prevented from causing serious damage to arm joints due to overlarge training.
