Optionally, at least two pull rods are arranged and uniformly distributed on the workbench.
Optionally, a positioning hole for connecting a pull rod is formed in the workbench, and the distance between the chuck and the workbench is adjusted by adjusting the length of the pull rod in the positioning hole.
Optionally, a side of the fixing hole facing the chuck is sloped.
Optionally, a gasket is arranged in the fixing hole, and the tensioning force of the expansion sleeve is adjusted by adjusting the thickness of the gasket.
Optionally, the gasket is provided in number.
Optionally, the pull rod is in threaded connection with the workbench.
Optionally, the pull rod is in threaded connection with the chuck.
