When the limiting rod 432 is in the second slide 443, the end of the pin 431 away from the limiting sleeve 44 is located in the through hole 311. At this time, the slider 42 can slide relative to the slide rail 41.

[0061] Optionally, two first connecting members 22 are provided, and the two first connecting members 22 are provided on both sides of the swing arm 21 along the first horizontal direction X and are symmetrically arranged with the swing arm 21 as the symmetry axis, and two second connecting members 23 are provided, and the two second connecting members 23 are provided on both sides of the swing arm 21 along the first horizontal direction X and are symmetrically arranged with the swing arm 21 as the symmetry axis. In this embodiment, since most vehicle models are provided with two tailgate stays 100 along the vehicle width direction, the above setting can simultaneously test the two tailgate stays 100 of the actual vehicle along the vehicle width direction. This setting improves the test failure on the one hand, and can further simulate the working scene of the tailgate stay 100 in the actual vehicle on the other hand.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
