Super-equal length hammer apparatus vibration training and information feedback trainer

The invention relates to a hammer training device, particularly to a super-equal length hammer apparatus vibration training and information feedback trainer applied to hammer strength training and solves the problem of absence of a training device integrating strength training for the final push of the hammer and vibration to directly reinforce stimulus to the throwing arm and providing effective training and monitoring for the athlete to handle the optimal time of fast strength. The trainer comprises a heavy hand-holding component, a shaking support, a main quivering component, a vibrating component, a fixing plate, an information feedback mechanism, a travel mechanism and two travel switches. The information feedback mechanism comprises a projector, a video tape recorder, a wall display screen and a pressure sensor. The shaking support comprises a retainer force measurement component, a circular plate, a plurality of retainer rings, a plurality of ejection blocks, a plurality of support legs different in lengths, a plurality of first springs, a plurality if support leg connecting seats and a plurality of connection beams. Each support leg comprises an upper support, a support sleeve and a pin.
