[0022] The front fixing seat 30 is provided with a locking pin 34 which can be elastically retracted, and the front fixing seat 30 is also constructed with a front fixing seat guide inclined surface 37 .

[0023] Rear pins 48 are fixed on both sides of the rear end of the step platform plate 40, and front pins 47 are fixed on both sides of the front end. The rear pin 48 cooperates with the first U-shaped groove 21 provided on the rear fixing seat 20, and the front pin 47 cooperates with the second U-shaped groove 35 provided on the front fixing seat 30. The front fixing seat 30 is also provided with a front fixing seat circular hole 36. The first U-shaped groove 21, the second U-shaped groove 35 and the front fixing seat circular hole 36 on the same printing unit 10 are coaxially arranged, and the front fixing seat guide inclined surface 37 and the front fixing seat circular hole 36 are on the same circumference.

[0024] Handles 41 are provided on both sides of the front end of the footrest platform 40 along the width direction. Positioning pins 42 are installed on the handles 41. The handles 41 can be stretched and moved forward and backward relative to the footrest platform 40 to achieve the engagement or disengagement of the positioning pins 42 with the front fixing seat circular holes 36 of the front fixing seat 30.

[0025] The front end of the foot platform 40 is provided with foot platform guide inclined surfaces 46 on both sides of the bottom surface along the width direction, and the front end of the foot platform 40 is provided with foot platform pin holes 49 on both sides along the width direction. After the foot platform 40 is rotated upward by 90° from the horizontal position, the locking pin 34 is guided by the foot platform guide inclined surfaces 46 and then fitted into the foot platform pin hole 49.

[0026] A compression spring seat 31 is fastened on the front fixing seat 30, and a locking pin 34 passes through the front fixing seat 30 and extends into the guide hole of the compression spring seat 31, and is locked and connected by a handle 32. A compression spring 33 is sleeved on the locking pin 34, and both ends of the compression spring 33 are respectively pressed against the inner end surfaces of the front fixing seat 30 and the pin body locking part 341 of the locking pin 34.

[0027] The handle 41 is connected to the foot platform board 40 through a guide column 43 and a guide rod 44. The guide column 43 and the guide rod 44 respectively pass through the guide connection holes on the foot platform board 40 and are fixedly connected to the handle 41. A guide rod compression spring 45 is sleeved on the guide rod 44. One end of the guide rod compression spring 45 is pressed against the foot platform board 40, and the other end is pressed against the end portion of the guide rod 44.

[0028] like Figures 1 to 7 As shown, the working process of the product of the present invention is as follows: in the initial state, the foot platform board 40 is in a horizontal state. Taking the foot platform board 40 rotating to the upper right as an example, when the left handle is pulled forward, the positioning pin on the left is disengaged from the circular hole of the front fixing seat on the left. At this time, the foot platform board 40 can rotate upward around the first U-shaped groove 21 and the second U-shaped groove 35 on the right side. When the foot platform board 40 rotates to nearly 90 degrees, the locking pin 34 on the right front fixing seat 30 slides forward under the guidance of the corresponding foot platform board guide inclined surface 46. When the foot platform board 40 rotates to 90 degrees, the foot platform board pin hole 49 on the foot platform board 40 is coaxial with the corresponding locking pin 42. Under the action of the corresponding compression spring 33, the locking pin 42 automatically enters the foot platform board pin hole 49 and locks the foot platform board 40 at the 90 degree position.

[0029] When it is necessary to place the vertically flipped foot platform board 40 to a horizontal position, the above-mentioned action steps are followed, and the handle 32 on the right is pulled forward so that the locking pin 34 on the right is disengaged from the corresponding foot platform board pin hole 49. At this time, the foot platform board 40 can rotate to the lower left around the rear fixing seat 20 and the front fixing seat 30 on the right; when approaching the front fixing seat on the left, under the guidance of the left front fixing seat guide inclined surface 37, the left locating pin 42 pushes the left handle 41 to slide forward, and the foot platform board 40 continues to rotate toward the lower left. When the left locating pin 42 is coaxial with the left front fixing seat circular hole 36, under the action of the left guide rod compression spring 45, the left locating pin 42 automatically enters the foot platform board pin hole 49 backward to lock the foot platform board 40.
