[0025] By means of the provided spring 21, the protective cover 7 can be retracted toward the bottom at any time. When the battery pack is subjected to a vibration test, the battery pack can be shielded, thereby improving the safety of the test. By starting the provided vibration motor 4, the mounting platform 6 can be driven to vibrate, thereby allowing the battery pack to be tested. By rotating the provided positioning assembly 9, the threaded rod 11 can be driven to rotate, so that the movable column 12 can be threadedly connected to the threaded rod 11.
