Under the action of the spring 403, the plug plate 49 moves to the left and slides into the hole groove 48, thereby fixing the protective cover 45, thereby providing better protection for the test equipment 43. By holding the two handles 42, The protective shell 41 can be lifted, and the limit block 30 is aligned with the set limit groove 32, so that the limit block 30 slowly slides into the limit groove 32. The set limit groove 32 will limit the protective shell 41 to a certain extent to prevent the movement of the protective shell 41. At the same time, the protective shell 41 will contact the roller 37, driving the roller 37 to move backward, so that the slider 38 moves along the slide groove 35, so that the spring 39 is compressed.
