The first hinge 2 and the second hinge 3 are linked, and the stopper 1 is connected to the first hinge 2 and the second hinge 3 respectively. The ball pin 4 comprises a ball head 41, a connecting section 42 and a supporting section 43. One end of the connecting section 42 is connected to the ball head 41, and the other end of the connecting section 42 is connected to the supporting section 43. The ball head 41 and the connecting section 42 are clamped in the mounting groove at the connection between the first hinge 2 and the second hinge 3. The outer diameter of the ball head 41 is equal to the outer diameter of the supporting section 43, and the diameter of the connecting section 42 is less than the diameter of the supporting section 43.

[0026] The second hinge 3 includes a mounting plate 31 and a mounting block 32. The mounting block 32 is connected to the side of the mounting plate 31, and the mounting block 32 is spaced apart from the connecting block 23 of the first hinge 2. The mounting block 32 includes a first mounting block 321 and a second mounting block 322. The first mounting block 321 is provided with a mounting hole, and the second mounting block 322 is provided with a mounting groove matching the ball pin 4.

[0027] More specifically, it is used to test and verify the door opening and closing parts - the limiter 1. The product is tested for opening and closing force in a simulated real vehicle state after being installed on the vehicle. It has a first hinge 2 simulating the vehicle body side connection on the second hinge 3 simulating the vehicle door by fixing the vehicle body side to push the vehicle door side to measure the force generated when the limiter 1 is opened and closed. After the fixture is fixed, it needs to be connected with the ball pin 4 of the base for positioning.
