[0014] Preferably, a slot is provided inside the lower side of the bench press rod, and the outer wall of the inclined block is arranged on the inner wall of the slot.

[0015] Working principle: When the device is needed, first control the specified bench press weight by rotating the counterweight plate at both ends of the bench press rod. At this time, the weight of the counterweight plate will press the bench press rod downward, and then apply pressure through the support belt sliding plate, and then transmit the pressure to the pressure sensor connected to the first spring through the first spring to display the weight on the display, and the outer walls of the connection boxes at both ends are provided with displays, and then the counterweight plate can be added to the initial gravity through the display to display the pressure at both ends to prevent the risk of injury. Then lie on the mat on the upper surface of the support frame, hold the handles on both sides of the bench press rod, set the number of reciprocating times and speed, and turn on the motor. The output end of the motor can drive the eccentric wheel to rotate, and then the eccentric wheel can drive the transmission plate to rotate with the outer wall of the support plate as The rotating point rotates back and forth, and at this time the transmission plate can drive the support block to move up and down through the connecting rod, so that the connecting box on the inner wall of the positioning frame at both ends can be driven to move up and down regularly through the U-shaped frame, and the up and down movement of the bench press rod is assisted by the support. At this time, the trainee can perform regular reciprocating bench press, so as to ensure that the muscles are in a state of dynamic tension, which can more effectively stimulate muscle fibers, promote muscle growth and physical fitness, and ensure the safety of training. At this time, the heart rate data can be recorded by the pressure sensing box on the palm of the hand when holding the handle, so as to feedback the training effects of different reciprocating times and speeds during training. When the reciprocating distance of the bench press rod needs to be adjusted, the rotating handle drives the sliding column to rotate, and then the sliding column can drive the limit The positioning plate rotates on the inner wall of the circular cavity. When the limiting plate rotates to the groove of the support frame, the second spring rebounds through the fixing box, which can push the pressure plate to slide inward, so that the limiting plate can be separated from the inner wall of the circular cavity until the first bevel gear is meshed with the second bevel gear. At this time, the turning handle is turned again, and the turning handle can drive the first bevel gear to rotate through the sliding column, and then the first bevel gear can drive the screw rod to rotate inside the frame through the second bevel gear, and the screw rod drives the moving block to slide left and right on the inner wall of the frame through a threaded connection, so that the positioning block can be driven to slide on the inner wall of the transmission plate through the support plate to adjust the rotation position of the transmission plate, thereby adjusting the reciprocating distance of the bench press rod, so as to achieve accurate stimulation of different muscle groups and adapt to different The effect required in the training stage, while holding the handle tightly, turning the handle, the handle can drive the inclined block to rotate synchronously, and when the inclined block contacts the inclined surface of the bench press rod, the inclined block will be separated from the inner wall of the slot until it is completely squeezed to the inner wall of the handle, and then the handles at both ends can be slid relative to the outer wall of the bench press rod to adjust the comfortable holding position, and then the handle is rotated again. When the inclined block slides to the position of the slot, the third spring rebounds through the stop block, which can push the movable plate to move upward, and then drive the inclined block to slide to the inner wall of the slot through the fixed column, thereby fixing the position of the handles at both ends, so as to achieve the effect of fitting different human body proportions and meeting different training goals, and at the same time, the reciprocating distance adjustment can further improve the versatility and reliability of the device.

[0016] The present invention provides a physical training device with automatic feedback function. It has the following beneficial effects:

[0017] 1. The present invention starts the motor, and its output end drives the eccentric wheel to rotate. The eccentric wheel causes the transmission plate to reciprocate with the outer wall of the support plate as the rotation point. The transmission plate drives the support block to move up and down through the connecting rod, and then the U-shaped frame drives the connecting box to move up and down regularly. Then, by observing that the weight displayed on the display is gradually smaller than the weight after weighting, it can achieve gradual training and improve the training efficiency and safety.

[0018] 2. The present invention drives the sliding column to rotate by rotating the handle, and the sliding column causes the limit plate to rotate on the inner wall of the circular cavity. When the limit plate rotates to the groove of the support frame, the second spring rebounds and pushes the pressure plate to make the limit plate separate from the inner wall of the circular cavity, and the first bevel gear meshes with the second bevel gear. The handle is rotated again, and the second bevel gear drives the screw rod to rotate, so that the moving block moves, thereby adjusting the rotation position of the transmission plate and the reciprocating distance of the bench press rod, so as to achieve the effect of accurately stimulating different muscle groups and adapting to the needs of different training stages.

[0019] 3. The present invention drives the inclined block to rotate by rotating the handle. When the inclined block contacts the inclined surface of the bench press rod, it is squeezed to the inner wall of the handle. Then the handles at both ends are slid on the outer wall of the bench press rod to adjust the position. Thereafter, the handle is rotated again. When the inclined block slides to the slot position, the spring rebounds and pushes the movable plate, driving the inclined block to slide into the slot to fix the handle position, thereby achieving the effect of fitting different body proportions, fitting different human body proportions, and training needs.

[0020] 4. The present invention can change the force angle and stretching degree of the muscles by adjusting the reciprocating distance of the bench press rod, thereby bringing new stimulation to the muscles. At the same time, it can adapt to different training goals of different trainees and cooperate with the position of the handle to help different trainees feel the force of the pectoralis major muscle and achieve better training effect, thereby achieving the effect of improving the applicability and flexibility of the device.
