Working principle: before the training device is used, the pre-installation operation of the balancing weight is needed, and the specific operation steps are as follows: when the two-way screw rotates, two internal thread blocks are driven by the screw threads of the two-way screw and the limit rod cooperates with two limit rods to move close to or far away from the rolling rods, so that the rolling rods expand and contract, when the expansion distance of the rolling rods at two sides exceeds that of the balancing weights, holes in the middle of the balancing weights are aligned with the suspenders at two sides of the bottom of the top plate and sleeved in the holes, and then the driving motors are started to reversely rotate, so that the two rolling rods perform approaching movement, and the balancing weights are supported. After the pre-installation work of the balancing weights is completed, normal leg muscle training and evaluating movement can be started, before the device is used, the supporting brackets rotatably connected with the two sides of the middle part of the extension frame keep a bearing state, namely the long ends are supported at the bottoms of the balance weight transverse plates, so that the leg brackets cannot rotate downwards, the leg brackets are locked, a trainer firstly enters the bearing frame and sits on the stool, the moving plate slidably connected with the middle part of the bearing frame can be driven to move forwards and backwards by starting the two first electric push rods fixedly connected with the front part of the U-shaped frame, the front part and the rear part of the stool are regulated, the second electric push rods arranged on the two sides of the front part of the bearing frame are started to operate, the front position frame is driven to integrally move forwards and backwards at the top part of the guide plate, the heel lifting and pressing mechanism and the intermittent triggering mechanism can be adjusted in front and back positions, after a trainer adjusts the device to be suitable for the user, the trainer firstly stands on the foot to place the toe position of the foot on the front part of the top surface of the pedal, then rotates the two support brackets rotationally connected with the middle part of the extension frame to ensure that the leg bracket and the counterweight transverse plate integrally recover the downward rotation capacity and put on the front part of the thigh of the trainer, the rear foot part of the trainer is stepped on the upper part of the rotating plate, the trainer puts down the heel as low as possible, the bottom surface of the rotating plate is attached to the rear part of the surface of the pedal, a small amount of balancing weights are sleeved on the upright rods at the two ends of the counterweight transverse plate in advance before the training, if the balancing weights are increased along with the increase of the training degree, the trainer lifts the counterweight transverse plate again at the moment and rotates the two supporting brackets to support the counterweight transverse plate, and then sequentially starting a plurality of driving motors from bottom to top to drive the two-way screw rods to rotate, so that the rolling rods move away from each other, when the distance between the two rolling rods is larger than the diameter of the balancing weights, the balancing weights fall off from the bottom of the top plate along the straight line of the hanging rod opposite to the vertical rods and fall onto the balancing weight transverse plate, a trainer is not required to manually add the balancing weights from the training device, in the training process of the trainer, the leg brackets can swing up and down in an arc shape along with the heel lifting training, when the leg brackets repeatedly swing forward and backward, a first bevel gear fixedly connected with one end side edge of the leg brackets can drive a second bevel gear in meshed connection with the leg brackets to rotate, the second bevel gear synchronously drives the outer toothed ring to repeatedly rotate forward and backward, and as the outer toothed ring is meshed with one side of the rack, when the outer toothed ring repeatedly rotates forward and backward, the drive rack drives the push rod fixedly connected with the bottom of the drive rack to push the rear lower side of the swing rod, the drive pawl can push the ratchet wheel to rotate in the pushing process, and when the push rod is retracted, the swing rod can reset under the elastic action of the reset spring and drive the drive pawl to synchronously move, and the check pawl always clamps one end of the ratchet wheel under the elastic action of the torsion spring, so that the ratchet wheel is prevented from rotating, when the ratchet wheel intermittently rotates, the trigger plate fixedly connected with one side of the trigger plate can contact the inclined top button arranged at the front part of the signal transmitter, so that the trigger plate retracts to trigger an electric signal, and the electric signal is transmitted to the sounder through a connecting wire, an encouraging sound effect or a self-defined audio frequency is generated, the trainee can carry out voice meter in different stages and encouragement, the trainer can self-define different sound effects corresponding to different heel training times, a certain excitation atmosphere is generated in the boring body-building exercise, in the actual training process of the trainer, the rotating speed of the rotating plate can be monitored in real time through the angular speed sensor arranged inside the pedal, and the trigger plate can be matched with the bow-shaped spring through the sliding ring, the two opposite to the user can exercise the two opposite sides of the training device can be matched with the pedal, the two opposite to each other can realize the accurate training device in the proper training range, the accurate training effect can be realized, and the training device can be compared with the two-stage training device can be used for the training device to realize the proper training device through the training device, meanwhile, the training atmosphere and the training power can be improved in a voice excitation mode in the training process of a trainer, and the effect of the user on evaluating the strength of the lower leg and training is improved.
