For the ease of the clamping of the anchor clamps other end, described axial screw is impermeable blind hole.
Equally for the ease of the clamping of the anchor clamps other end and be easy to processing, described column is a cylinder, and described cylinder is divided into three sections, and first section for being provided with the major diameter of axial screw, and second section be the tapering transition section, and the 3rd section is the reduced diameter section that is used for clamping.
For the nut sleeve that is used in locking is convenient to install difficult drop-off, be provided with T shape half the circumference of the sleeve where it joins the shoulder at described nut sleeve one end, described T shape half the circumference of the sleeve where it joins the shoulder matches with the T connected in star that is arranged on described axial long hole one side.
Rotate with anchor clamps for clamping screw can not withstood screw tap after nut sleeve cooperates, described T connected in star is arranged on a side that is positioned at described axial screw in the described axial long hole.
Do not produce movement interference between nut sleeve and the screw tap in order to make, described nut sleeve is provided with cancave cambered surface in the end that is provided with T shape half the circumference of the sleeve where it joins the shoulder, and described cancave cambered surface and described axial screw are suitable, and the cancave cambered surface of described T shape half the circumference of the sleeve where it joins the shoulder is a little less than the flank of described axial screw.
For nut sleeve can not rotated with respect to the axial long hole on the anchor clamps, described nut sleeve is being positioned at the platform that is provided with the two ends symmetry on the described T shape half the circumference of the sleeve where it joins the shoulder outer surface once, and described platform is used for being slidingly matched with the both sides of described axial long hole.
In order to make these anchor clamps can be durable in use, described anchor clamps be preferably made by tool steel.
Advantage of the present utility model and beneficial effect are: this tapping clamp has simple in structure, be easy to processing and manufacturing, with this tapping clamp clamping after on the unit head of tapping machine, can regulate the length that its screw tap stretches out screw tap clamp according to the depth in processed hole, can use the screw tap of the least possible gauge lattice so, not only can carry out tapping but also can carry out tapping shallow bore hole to deep hole.
