The use method and the advantages of the invention are as follows: when the wrestling waist training device is used, the working process is as follows:

the method comprises the following steps: as shown in fig. 1, when a player performs backward waist training, firstly, the feet are fixed by a first binding belt 2, then the lower side of the upper knee of the lower leg is fixed by a second binding belt 5, and finally, a third binding belt 10 is sleeved on the arm and fixed at the shoulder position of the player to complete the preparation work;

in the process of the back-bending of the athlete, a pulling force is applied to the second pulling rope 12 through the shoulder part and the third binding belt 10, so that the second pulling rope 12 drives the chain 15 to move, the chain 15 pulls the rack 4 to move rightwards through the first pulling rope 8, as shown in fig. 2, the rack 4 compresses the first spring 24 through the lug 22, and the first spring 24 obtains a restoring force which applies a counterforce to the shoulder part of the athlete through the rack 4, the first pulling rope 8, the chain 15, the second pulling rope 12 and the third binding belt 10 to increase the resistance of the back-bending of the athlete, thereby being beneficial to improving the back-bending waist training effect of the athlete;

as shown in fig. 5, the chain 15 moves and drives the chain disc 27 and the chain wheel 43 to rotate, and the chain wheel 43 plays a role in stably connecting the chain 15 and the chain disc 27, so as to ensure the stable operation of the speed reducing mechanism;

when the athlete leans backwards too fast or falls backwards, the third binding band 10 pulls the chain 15 to move too fast through the second pulling rope 12, so that the chain 15 drives the chain disc 27 to rotate too fast, as shown in fig. 3, the chain disc 27 rotates and simultaneously drives the sliding block 29 to rotate, so that the sliding block 29 obtains a centrifugal force, the centrifugal force applied to the sliding block 29 is increased when the rotation speed of the chain disc 27 is increased, the sliding block 29 drives the friction block 31 to move towards the direction far away from the circle center of the chain disc 27 through the first sliding rod 35, when the upper surface of the friction block 31 is in abutting contact with the bottom surface of the friction ring 13, the rotation of the chain disc 27 is decelerated through the friction force between the friction block 31 and the friction ring 13, so that the speed of the athlete leaning backwards or falls backwards is reduced, the athlete is prevented from being difficult to control the body of the athlete to fall backwards too fast, and the damage degree caused by the athlete when falling backwards is reduced, the passive protection function is realized when the athlete leans back on the waist;

when the athlete stands for resetting, the third binding belt 10 and the second pulling rope 12 are not pulled, so that the rack 4 moves leftwards under the restoring force of the first spring 24 and the first pulling rope 8 applies reverse pulling force to the chain 15, the chain disc 27 rotates reversely, the third binding belt 10 is driven to reset through the second pulling rope 12 for next use, when the rotating speed of the chain disc 27 is reduced or stopped, the sliding block 29 moves towards the center of the chain disc 27 through the acting force of the second spring 30, so that the chain disc 27 drives the friction block 31 to be far away from the friction ring 13, and the deceleration mechanism can ensure that the backward leaning action of the athlete is not interfered in a normal training state;

step two: as shown in fig. 3 and 4, when the athlete backward speed is not controlled to fall too fast, the chain 15 drives the chain disc 27 to rotate fast, so that the power slide block 29 obtains a larger centrifugal force, and the friction ring 13 compresses the spring third 34 through the friction block 31, so that the spring third 34 obtains a restoring force, at the same time, the friction block 31 drives the slide rod first 35 to move downwards, the downward movement of the slide rod first 35 applies a downward force to the top block 40, when the height of the top block 40 is lower than that of the spring fourth 41, the included angle opening of the two connecting rods second 39 is upward, so that the two sliding sleeves 38 approach each other under the force of the spring fourth 41, and the top block 40 is pushed to move downwards through the two connecting rods second 39, so that the top block 40 drives the toothed plate 32 to move downwards through the suspension rod 42 and engage with the teeth on the upper surface of the gear ring 33, thereby preventing the rotation of the slide block 29, further locking the chain disc 27, and making the chain disc 27 unable to rotate, thereby preventing the athlete from continuously falling through the chain 15, the second pull rope 12 and the third binding belt 10, and playing a role in protecting the athlete;

after the danger of the athlete is relieved, the athlete can push up the toothed plate 32 manually, and the toothed plate 32 pushes the ejector block 40 to move upwards through the suspension rod 42, so that the toothed plate is higher than the spring four 41 and is in abutting and buckling contact with the lower end of the sliding rod one 35, and the athlete can reset and reuse the athlete, and the operation is simple and convenient;

step three: as shown in the first step, when the rack 4 moves rightwards, the first gear 21 drives the shaft rod 20 to rotate, as shown in fig. 1 and 2, the shaft rod 20 drives the screw rod 18 to rotate through the bevel gear set 19, so that the screw rod 18 drives the threaded sleeve 17 to move rightwards through thread transmission, further the threaded sleeve 17 applies thrust to the base plate 44 through the first connecting rod 6, the base plate 44 rotates clockwise, the base plate 44 synchronously rotates to approach to the back of the athlete while the athlete leans backwards, and therefore the athlete can be supported when the athlete cannot control the athlete to fall, the athlete is protected, and the training safety is improved;

when the rack 4 moves leftwards under the action of the restoring force of the first spring 24, the rack 4 drives the shaft rod 20 to rotate reversely through the first gear 21, so that the shaft rod 20 drives the screw rod 18 to rotate reversely through the bevel gear set 19, the screw rod 18 drives the threaded sleeve 17 to move leftwards through thread transmission, the threaded sleeve 17 applies pulling force to the base plate 44 through the first connecting rod 6, the base plate 44 rotates anticlockwise to reset, and the base plate 44 synchronously and automatically resets when a sportsman resets or stops moving;

after the training of sportsman, loosen and remove bandage three 10, bandage two 5 and bandage one 2 can, whole device need not another alone's help when training sportsman's back-up waist, can realize single autonomic safety training, improves training efficiency.

the method comprises the following steps: the falling speed of the telemechanical is reduced when the telemechanical falls through the speed reducing mechanism on the cross beam (9);

step two: when the speed reducing mechanism is not enough to reduce the speed of the athlete, the speed reducing mechanism is driven by the speed reducing mechanism to lock the speed reducing mechanism, and the athlete is stopped from continuously falling down;

step three: and as shown in the step one, the athlete synchronously drives the back cushion mechanism to lift through the speed reducing mechanism when performing waist training so as to support and protect the athlete when the athlete falls down, and the back cushion mechanism automatically resets when the athlete resets or stops the sports.
