A fitness equipment spring counterweights balancer, comprising:

• a hand wheel, a lead screw, a framework connecting nut, a gravity scale indicating device frame, a plane press plate, a plane press plate guiding pillar, an upper frame beam, an upper pulley block, a lower pulley block, a spring guiding pillar, an upper spring seat, a spring, a lower spring seat, a spring guiding pillar connecting nut, a lower frame beam, a vortex track, a big wheel, a steel wire rope connecting the pulley block and the vortex track, a steel wire rope connecting the big wheel and the fitness equipment;
• wherein the hand wheel is fixed at the top of the lead screw;
• the spring is arranged between the upper spring seat and the lower spring seat;
• after going through the spring and the upper spring seat and the lower spring seat, two ends of the spring guiding pillar are connected to the upper frame beam and the lower frame beam respectively, forming a foundation framework;
• the spring together with the upper spring seat and the lower spring seat move along the spring guiding pillar;
• a thread lead screw is arranged at the lower end of the spring guiding pillar;
• the spring guiding pillar connecting nut is mounted on the thread lead screw of the spring guiding pillar;
• the gravity scale indicating device frame is fixed on the upper frame beam;
• one end of the lead screw is connected with the hand wheel;
• the other end of the lead screw passes through the framework connecting nut which is fixed on the gravity scale indicating device frame;
• an upper end of the plane press plate guiding pillar is connected with the plane press plate;
• a lower end of the plane press plate guiding pillar passes though the upper frame beam and is connected to the upper spring seat;
• the upper pulley block passes though the upper spring seat and is mounted on the upper frame beam, the lower pulley block is mounted on the lower spring seat;
• one end of the steel wire rope connecting the pulley block and the vortex track is fixed to one side of the lower pulley block, then goes around the upper pulley block and the lower pulley block;
• the other end of the steel wire rope connecting the pulley block and the vortex track is connected with the vortex track, the vortex track is engaged with the big wheel synchronously or asynchronously;
