The pin shaft assembly 5 includes an upper seat plate 51. There are two upper seat plates 51, and the two upper seat plates 51 are respectively arranged on the side walls of the upper left roller column 441 and the upper right roller column 443; there are two lower seat plates 52, and the two lower seat plates 52 are respectively arranged on the side walls of the left support column 32 and the right support column 33, and the positions of the two upper seat plates 51 correspond to the positions of the two lower seat plates 52 one by one up and down; there are two locking outer screws 53, and the two locking outer screws 53 are respectively rotatably arranged on the side walls of the lower left roller column 421 and the lower right roller column 423.
