The side of the positioning block 206 is slidably connected to the slider 205, and the number of the clamping plates 207 is set to two, and they are symmetrical to each other along the vertical center axis of the mounting block 203. A lubricating device 3 is provided on the top of the protective plate 101, and the lubricating device 3 includes an extrusion rod 301, which is fixedly connected to the top of the stacking mechanical claw 105, and an oil tank 302 is fixedly connected to the side of the support frame 103.
