4. A treadmill for physical training with reversing function according to claim 1, characterised by the fact that the treadmill (1) is connected in rotation with the side frame (2) through the rotation shaft (18) and the clamping frame (19).

5. A treadmill for physical exercise with reversing function according to claim 1, characterised by the fact that the running deck (1) is articulated to the base plate (16) by means of two hydraulic telescopic rams (29) and a top ring (31).

6. A treadmill for physical exercise with reversing function according to claim 3, characterised in that the rotation lever (25) and the suction pump (26) are in rotational connection with the outer wall of the running deck (1) through the rotation lever (25).

7. The treadmill with reversing function for physical exercise as claimed in claim 1, wherein the method of using the treadmill comprises the following steps:

the method comprises the following steps: firstly, the running machine needs to be moved to a position needed to be used, when the running platform (1) of the running machine is too long in length or blocked due to limitation of spatial layout of a placement position in the moving position process, the reversing mechanism (11) is started through the PLC (3), the PLC (3) controls the reversing motor (17) to be started, the reversing motor (17) drives the rotating shaft (18) to rotate, the clamping frame (19) is driven to rotate by rotation of the rotating shaft (18), so that the whole running platform (1) is rotated to adjust the angle to shorten the length and avoid obstacles, and when the PLC (3) controls the reversing motor (17) to drive the rotating shaft (18) to rotate for 90 degrees, the running platform (1) is transversely folded, and the length is shortened to be minimum;

step two: when the treadmill is used, when the drive box (5) is controlled to start through the PLC (3), the drive motor (14) in the drive box (5) drives the running belt (4) to rotate, and a user can stand on the running table (1) to perform physical exercise;

step three: when the exercise intensity needs to be adjusted, when the PLC (3) starts the adjusting hydraulic pump (28), the adjusting hydraulic pump (28) drives the hydraulic telescopic ejector rod (29) to stretch to drive the top ring (31) to move up and down, so that the running table (1) is driven to adjust the inclination angle, the larger the stretching amplitude of the hydraulic telescopic ejector rod (29), the larger the inclination degree of the running table (1), and the higher the physical exercise intensity;

step four: after the running table (1) finishes reversing and adjusting the inclination angle, the built-in motor (23) and the suction pump (26) are started through the PLC (programmable logic controller) (3), the built-in motor (23) drives the driving shaft (24) to rotate, so that the rotating rod (25) is driven to rotate, the suction disc (27) is abutted to the ground, and the suction pump (26) provides adsorption force for the suction disc (27) and fixes the position of the running table (1).
