The specific embodiment

Below in conjunction with accompanying drawing, the utility model is done further detailed narration.

Please refer to Fig. 1 and Fig. 4, the utility model provides a kind of hand tapping machine, comprise base 1, column 2, tapping structure 3 and handle 6, base 1 is used for the usefulness of placement and fixation workpiece, column 2 is fixedly connected on the base 1, tapping structure 3 is put on the shelf by one and 5 is connected with column 2, and the relative position that a locking nut 4 is regulated tapping structure 3 and column 2 is set, and handle 6 is movably connected in tapping structure 3 upper ends.

Please refer to Fig. 2 and Fig. 3, tapping structure 3 comprises connecting axle 31 and work head 32, connecting axle 31 is fixedlyed connected with 5 relative positions of putting on the shelf, work head 32 is fixedly connected on the lower end of connecting axle 31, connecting axle 31 bottoms are provided with a groove 311, under handle 6 effects, connecting axle 31 and work head 32 can be along the direction activities perpendicular to base 1.In this way, utilize the deadweight of work head 32, work head 32 is descended automatically, turning handle 6 gets final product tapping then, and counter-rotation handle 6 can be return.
