[0011] The utility model detects the degree of curvature of the curved surface of the front crossbeam through the cooperation setting between the fixing component and the curved surface detection component; the product is placed between the first fixing seat and the second fixing seat and fits with the first fixing seat, the push rod is rotated to drive the abutment plate to move forward and abut against the product to achieve fixation, and then the corresponding standard curved plate is selected according to the model of the front crossbeam. Different models of front crossbeam products only need to replace the corresponding standard curved plate to achieve detection, which effectively improves the practicality of the inspection tool. The standard curved plate is assembled on the top of the connecting seat via a connecting piece, and the adjusting wheel is turned to rotate the screw. Under the action of the threaded cooperation, the screw drives the connecting seat to move along the slide groove toward the product, and the standard curved plate is fit with the curved surface structure of the front crossbeam to determine whether the degree of curvature meets the standard.
