Since the threaded rod 52 and the threaded block 53 are threadedly connected, and the threads of the outer walls at both ends of the threaded rod 52 are in opposite directions, and the threaded block 53 can slide and limit on the inner wall of the support box 2, the threaded block 53 will drive the positioning plate 55 to move toward the direction close to the automobile hood assembly through the connecting block 54, and clamp the automobile hood assembly to position it, thereby ensuring its stability during the inspection process, and will not easily cause deviation and shaking, thereby further improving the accuracy of the inspection data.

When the half gear 48 rotates to a certain position and does not mesh with the rack 408, the rack 408 has no thrust. The spring 49 in the compressed state can push the slide bar 401 to move downward. The slide bar 401 drives the impact block 404 to move downward through the long shaft 403 to impact the automobile hood assembly, thereby testing the impact resistance of the automobile hood assembly. At the same time, under the mutual cooperation and transmission of the worm wheel 44 and the worm 42, multiple impact blocks 404 can impact and then the impact resistance of multiple points of the automobile hood assembly can be tested, achieving good detection efficiency. Enhance the practicality of the device.
