Four groups of installation grooves are opened at the top of the limit plate, and threaded rods are installed inside the four groups of installation grooves through bearings. The threads of the threaded rods at opposite positions are opposite to each other. The outer side of the threaded rod is engaged with an installation block, and an extrusion block is installed on the top of the installation block. The installation block can slide inside the installation groove. An installation cavity is opened inside the limit plate, and a first inert shaft, a second inert shaft, a first driven shaft, and a second driven shaft are connected to the inside of the installation cavity through bearings.
