The bottom frame 21 is rotatably connected to the base 1 through the main shaft 23.
[0023] The bottom frame 21 can swing back and forth along the main axis 23, thereby realizing the angle adjustment of the bottom support mechanism 2.
[0024] As attached Figure 2 As shown, the bottom support angle adjustment mechanism 3 includes a shaft 31, a fisheye connecting rod 32, a nut 33, a connecting frame 34, a connecting plate 35, a through hole 36, and a connecting block 37. The shaft 31 is provided on the side of the bottom frame 21. The shaft 31 is located directly above the main shaft 23 and is parallel to the main shaft 23. The shaft 31 passes through the hole of the fisheye connecting rod 32. The rod of the fisheye connecting rod 32 is threaded and has two nuts 33 threadedly connected to it. The rod of the fisheye connecting rod 32 passes through a vertical waist hole on the connecting frame 34. The connecting frame 34 is vertically fixed on the base 1.

[0025] When the fisheye connecting rod 32 moves back and forth within the vertical slot of the connecting frame 34, the bottom support mechanism 2 can be driven to swing back and forth by pulling the shaft 31. After the angle of the bottom support mechanism 2 is adjusted, tighten the nuts 33 on both sides of the connecting frame 34 until the two nuts 33 clamp the connecting frame 34, thus fixing the fisheye connecting rod 32 onto the connecting frame 34. After the angle of the bottom support mechanism 2 is adjusted, use bolts to pass through the through hole 36 and screw them into the screw hole of the connecting block 37 to fix the bottom frame 21 and the base 1 together.

[0027] The slide block 43 can move horizontally along the horizontal connecting plate 41. When the slide block 43 is in place, the two connecting blocks of the slide block 43 are tightened by bolts. The two connecting blocks can clamp the horizontal track on the horizontal connecting plate 41, thereby fixing the vertical rod 42 on the horizontal connecting plate 41 and realizing the adjustment of the horizontal position of the vertical rod 42.
[0028] The product's movable end adjustment bracket 5 includes a vertical connecting plate 51, a horizontal rod 52, and a slide block 53.

[0029] The slide block 53 can move up and down along the vertical connecting plate 51. When the slide block 53 is in place, the two connecting blocks 2 of the slide block 53 are tightened by bolts. The two connecting blocks 2 can clamp the vertical track on the vertical connecting plate 51, thereby fixing the horizontal rod 52 on the vertical connecting plate 51 and realizing the adjustment of the horizontal rod 52 in the vertical position.
[0030] The simulated car door mechanism 6 includes a frame 61 and a counterweight 62, with the counterweight 62 fixed on the frame 61.

When the rotating plate 71 is rotated to the position, the screw is passed through the arc-shaped strip hole 73 and screwed into the screw hole of the fixing block 72, so that the rotating plate 71 can be fixed at the current angle.
[0034] The method of use of this application is as follows: First, adjust the angle of the bottom support mechanism 2. Then, adjust the angle of the simulated car door mechanism 6 using the simulated car door angle adjustment mechanism 7. Next, adjust the horizontal position of the vertical rod 42 and the vertical position of the horizontal rod 52. Then, insert the ball heads of the vertical rod 42 and the horizontal rod 52 into the ball grooves at both ends of the limiter. Finally, by holding the handle 63, open and close the frame 61 to the corresponding positions, and measure the data of the limiter being tested.
