The invention has the beneficial effects that:

(1) the athlete ejection device for ice and snow sports and capable of improving training efficiency is characterized in that an ejection structure is arranged on a base frame, so that an athlete can be ejected through the elastic force in the ejection structure, the athlete can be conveniently trained, the ejection structure can be better worked through the matching with a stretching structure, the ejection structure can be positioned through a positioning structure when the ejection structure works, accidents caused by the fact that the athlete ejects the ejection structure is not loosened and does not stand stably are prevented, meanwhile, the athlete can be prevented from automatically sliding out of the ejection structure through a fixing structure, namely, when the athlete needs to be ejected, a sliding plate is pushed to drive a first connecting rod fixed on the sliding plate to slide, an upper second baffle fixed on the first connecting rod can be driven to slide, and the athlete stands on a push plate fixed on the second baffle, and a plurality of first springs are arranged between the sliding plate and the underframe, so when the sliding plate is loosened, the second baffle is driven to slide rapidly by the elasticity of the first springs, thereby the athlete can be driven to move rapidly on the push plate, when the second baffle does not slide any more, the athlete can slide out of the push plate by inertia, thereby the physical loss caused by long-time acceleration of the athlete can be avoided to influence the training efficiency, the push plate is rotationally connected with the rollers by the rotating shaft, so the athlete can accelerate better by the rotation of the rollers, the first springs can be prevented from being wound together by the first baffle arranged on the sliding plate, the first baffle is electrically connected with the motor by an external power supply to work, the belt pulley fixed at the output end of the motor is driven to rotate, because the fixed seat is fixed on the underframe, the rotating rod is rotationally connected with the fixed seat, and the belt pulley on the rotating rod and the belt pulley on the motor are driven by the belt, therefore, the motor can rotate to drive the rotating rod to rotate, two winding rollers are fixedly connected to the rotating rod to drive the two winding rollers to rotate simultaneously, a first pull rope is fixedly connected to the winding rollers, so that the first pull rope is wound by the rotation of the winding rollers, a fixing hook is fixedly connected to the first pull rope, and a fixing ring is fixedly connected to a pull ring fixed to a second baffle plate, so that the first pull rope drives the second baffle plate to slide through the pull ring and the fixing ring, thereby driving the sliding plate to slide, preventing the injury to personnel due to overlarge elastic force of a first spring when the sliding plate is manually slid, and preventing the motor from rotating due to the large elastic force of the first spring when the motor stops working due to the fact that a fixing sleeve is fixed on the underframe when the second baffle plate is pulled, thereby preventing the efficiency from being reduced due to the fact that the first clamping block on the first sliding block of the fixing sleeve is clamped with the pull ring, when ejection is needed, the fixing ring and the fixing hook are detached firstly, then the pedal is stepped to drive the third connecting rod to slide, the third connecting rod is fixedly connected with the first slide block through the second connecting rod, so that the first slide block and the first slide block are driven to slide, the first clamp block and the pull ring are not clamped any more, so that a sportsman can be ejected out through the elasticity of the first spring, the pedal can be pulled back after the pedal is loosened through the tension of the second spring, when the pedal is ejected, the third slide block is fixed in the push plate, and the second clamp block is fixedly connected on the fourth slide block sliding in the third slide block, when the push plate slides to a certain position, the second clamp block is clamped with the first clamp groove arranged on the bottom frame, so that the second clamp block does not slide any more when the push plate slides, so that the second pull rope can be pulled to slide, because the second slide block is fixedly connected with the other end of the second pull rope, and the second stay cord turns to through the leading wheel, consequently can stimulate third baffle lapse on second slider and the second slider, and elasticity through the fourth spring can make second fixture block and first draw-in groove carry out the block better, can upwards slide the third baffle after the second stay cord is not hard up through the elasticity of third spring, can prevent through the automatic roll-off push pedal of gyro wheel before the sportsman still does not launch and goes out through the third baffle.

(2) The athlete ejection device for ice and snow sports and capable of improving training efficiency can prevent the stability of an athlete from being poor and the athlete from easily falling down when the athlete is ejected due to overlarge elasticity of feet when the athlete is ejected by installing the protection structure on the chassis, can protect the athlete through the height and habit of the athlete by adjusting the structure, namely, the second baffle plate is fixedly connected with the first slide rod through the fourth connecting rod, so that the second baffle plate can drive the first slide rod to slide simultaneously by sliding, and because the sliding protection plate slides on the first slide rod, the foot and the upper body of the athlete can be simultaneously stressed through the protection plate, so that the stability of the athlete when the athlete is ejected is kept, because the two second slide rods slide on the first slide rod and are fixed through the fixing rods, the height of the protection plate can be adjusted by vertically sliding the second slide rods, when the height of guard plate is adjusted to needs, the pulling handle drives the third fixture block to slide, make third fixture block and second draw-in groove no longer block, thereby can drive the guide arm of fixing on the third fixture block and slide, adjust the fixed position after with the guard plate, loosen the handle, can pull back the third fixture block through the pulling force between the fifth spring between fifth slider fixed with the guide arm and the dead lever, block once more through third fixture block and second draw-in groove fixes the dead lever once more, prevent guard plate automatic sliding.
