[0056] The roller 364 plays a guiding role and is used to change the moving direction of the connecting belt 32.

[0057] The working principle of this application is described below with a preferred embodiment:

[0058] The seat body 1 and the slide rail body 2 are fixed on the supporting seat 31, and then one end of the connecting belt 32 is connected to the unlocking handle 21, and the other end of the connecting belt 32 is passed between the roller 364 and the U-shaped frame 363 and connected to the vertical plate 311.

The output end of the telescopic member 33 drives the groove wheel 352 to move through the bracket 351, and the groove wheel 352 drives the connecting belt 32 to move downward along the outer wall of the roller 364. At the same time, the connecting belt 32 drives one end of the unlocking handle 21 to tilt up. At this time, the slide rail body 2 is in the open state. When the output end of the telescopic member 33 is reset, the unlocking handle 21 is also reset. At this time, the slide rail body 2 is in the locked state, and the unlocking handle 21 completes a dynamic opening and closing. The unlocking handle is determined by counting the number of extensions and contractions of the telescopic member 33. 21 is opened and closed several times until the rebound law of the unlocking handle 21 is insensitive, so as to test the durability of the unlocking handle 21. When testing the movement durability of the slide rail body 2, the end of the connecting belt 32 away from the unlocking handle 21 is connected to the roller 364, so that the unlocking handle 21 is tilted. At this time, the slide rail body 2 is in a long-term unlocked state, and then the moving part of the slide rail body 2 moves back and forth in the fixed part of the slide rail body 2 to perform the durability test of the slide rail body 2. When different models of seat bodies 1 need to be tested, the transmission shaft 431 is driven to rotate in the bearing seat 31 by the handwheel 433. As the transmission shaft 431 rotates, the support plate 41 is driven to move laterally along the outer wall of the cross bar 42 through the slider 432, thereby expanding the distance between the compensation frame 411 and the vertical plate 311, and the compensation frame 411 cooperates with the bearing seat 31 to carry a larger seat body 1.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
