Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes:

[0028] 1. Movable connecting plate 1, with a first circular hole for the safety mechanism 6 to pass through; specifically, the movable connecting plate 1 is a ring-shaped structure, and the first circular hole is the inner circle of the movable connecting plate 1.

[0029] 2. Support frame 2, the support frame 2 includes: a fixing plate 7; a second circular hole is provided on the fixing plate 7 for the safety mechanism 6 to pass through; a plurality of annular grooves 8 are provided on the fixing plate 7 and around the second circular hole; an angle value 9 is engraved around one of the annular grooves 8.

[0043] Two base plates 22 are provided, and an angle steel upright plate 23 is fixedly connected (e.g., welded) to each base plate 22; the fixing plate 7 is provided between the two angle steel upright plates 23 and is fixedly connected (e.g., welded) to the two angle steel upright plates 23.

[0044] The present invention will be described below through a specific embodiment:

[0045] During testing, the safety mechanism 6 is assembled into the first circular hole of the movable connecting plate 1, and positioned by the positioning piece on the safety mechanism 6 and the positioning groove of the movable connecting plate 1. Then, the sealing cover 5 and the rubber sealing ring gasket 21 are connected to the movable connecting plate 1 using bolts 19 and wing nuts 20, thereby pressing the safety mechanism 6 to seal it. Tighten by hand-tightening and rotate to connect the airtight hose to the airtight connector 11, and turn on the air source. Rotate the movable connecting plate 1 to apply air pressure (instead of water pressure) to the safety mechanism 6, ensuring that a certain air pressure corresponds to a certain angle.

[0046] Specifically, rotate the movable connecting plate 1 to place the safety mechanism 6 at 80° (i.e., pointer 10 points to 80°), turn on the air source to inflate to a pressure value of 0.2MPa, and the safety mechanism 6 will not activate.

[0047] At this point, unscrew the hand-tightening needle 15 to release the air and reduce the pressure to 0 MPa. Then, rotate the movable connecting plate 1 to turn the safety mechanism 6 clockwise to 0° (i.e., pointer 10 points to 0°).

[0048] At this point, re-inflate the sealing cover 5 to 0.3MPa, and then slowly rotate the movable connecting plate 1. When the movable connecting plate 1 is placed at 25° (i.e., pointer 10 points to 25°), it does not move, meaning the product is still in the set state.

[0049] Adjust the air source pressure and release the air to 0.28±0.005MPa. Slowly rotate the movable connecting plate 1. When the pointer 10 points to a certain angle within the range of 35° to 65°, the safety mechanism 6 will normally engage the safety, which means it is in the released state.

[0050] The testing device has a simple structure, accurate measurements, and is easy to operate.
