Reciprocating fatigue test device for luggage pull rod

The utility model discloses a luggage pull rod reciprocating fatigue experiment device, belongs to the technical field of luggage detection, and solves the problem that when the volume of a tested luggage is increased from 20 inches to 28 inches or even 30 inches, a connecting belt cannot bind the luggage at a unified position. Comprising a bottom plate, a vertical machine shell fixedly connected to the top face of the bottom plate and an adsorption assembly moving on the top face of the bottom plate, and the adsorption assembly is coupled with a detection and control circuit. After the draw-bar box is manually placed, the control circuit detects the existence of the draw-bar box to control the air cylinder to push the adsorption assembly to move towards the draw-bar box, and after the distance between the adsorption assembly and the draw-bar box reaches a threshold value, the adsorption assembly exerts adsorption acting force on the draw-bar box in the horizontal direction; the pull rod of the draw-bar box i
