Abstract
The utility model discloses a threading clamp which is a cylinder. One end of the cylinder is provided with an axial prism hole in which a sleeve is equipped. A screw hole is equipped in the sleeve. The sidewall of the sleeve is provided with an axial through groove. The sidewall of the cylinder is provided with a through axial long hole. The position of the axial through hole corresponds with the position of the axial through groove on the side wall of the sleeve. A nut sleeve is inserted in the axial long hole and the axial through groove. The outer wall of the nut sleeve, the axial long hole and the axial through groove are in sliding fit. A bolt is equipped in the nut sleeve. The bolt is used for supporting the taper shank of a screw tap for preventing rotation relative to the clamp. The threading clamp has the following advantages: simple structure, and easy manufacture. After the threading clamp is equipped on a power head of a threading machine, the length of a screw tap clamp is adjusted according to the depth of the machined hole. Thus the screw taps in small number of specifications as possible can be used. Threading on the hollow hole and deep hole can be performed.
