The utility model is further set to: in described housing, be provided with the gear being meshed with tooth bar, be equipped with handwheel on support frame as described above, described handwheel and gear are circumferentially connected.

By adopting technique scheme, user can select direct lifting feed table or carry out lifting feed table height by rotating handwheel, while rotating handwheel, by gear drive, make the tooth bar of engagement increase, lifting feed table height, moves little, and control can add meticulous, meets hobby and demand that user is different.

The utility model is further set to: described feed table comprises helical blade, and described rotary power unit comprises motor, and described motor arranges output terminal, and described helical blade is connected with output terminal.

By adopting technique scheme, driven by motor helical blade rotates, and realizes the object of screw feeding, has advantages of simple in structure.
