However, the existing inspection tools for high-speed rail luggage racks are mostly inspection components of a single adaptation style, which can only perform pressure-bearing inspections on a limited number of high-speed rail luggage racks. The inspection performance is relatively single, and different inspection tools need to be set up to match the inspection work of luggage racks of different lengths. The inspection cost is high and the operation is relatively cumbersome. To this end, technicians in this field provide a flexible and adjustable high-speed rail luggage rack pressure-bearing inspection tool to solve the problems raised in the above background technology.

By turning the adjusting hand wheel 13, the transmission shaft 10 is driven to rotate, and then the transmission worm 11 is driven to rotate. The meshing transmission of the transmission worm 11 and the transmission worm wheel 12 is utilized to drive the corresponding clamping screw rod 2 to rotate, which serves as a driving source to push the tooling frame 4 to slide symmetrically to adapt to luggage racks of different lengths and models.
