In order to simulate the influence of the falling of heavy objects on the battery shell at different heights, the handle 12 can be rotated to drive the worm 11 to rotate, and then the threaded rod 15 is rotated through the worm wheel 14. Since the lifting plate 16 is connected with the threaded rod 15 through threads, the rotation of the threaded rod 15 will make the lifting plate 16 move up and down along the threaded rod 15, and the limiting rod 17 on the lifting plate 16 will slide in the limiting groove of the scale plate 18, so as to ensure that the lifting plate 16 stably rises or falls, and the current height value can be read according to the scale, and then the influence of the falling of the steel ball at different height changes on the shell when the shell is impacted by falling is tested. When the lifting plate 16 rises to the predetermined height, the ball storage plate 19 also rises together, and at this time, the steel ball used for testing can be placed in the ball storage groove 20 on the ball storage plate 19. The ball storage groove 20 is designed as an inclined structure, so as to facilitate the steel ball to slide to the falling groove 13 under the action of gravity, and finally fall from the falling opening 22 and directly impact the battery shell below, so as to simulate the impact situation that may be encountered in actual use. In the whole process, by adjusting the height of the ball storage plate 19, the falling height of the steel ball can be changed, so as to realize the testing requirements of different strength levels.
