Inner surface wall is provided with bayonet socket, and the screw tap wicking surface is welded with incisor, and incisor side is provided with chip area.
It is used as further describing for above-mentioned technical proposal：
The screw tap core is the cylindrical structural that metal material is made.
It is used as further describing for above-mentioned technical proposal：
The length of the screw tap core is 30mm.
It is used as further describing for above-mentioned technical proposal：
The extension bar and handle are cylindrical structural, and the diameter of extension bar is more than handle.
It is used as further describing for above-mentioned technical proposal：
The incisor is provided with four altogether, and four incisors are symmetricly set on screw tap wicking surface.
In the utility model, handle side is welded with fixed block first, and fixed block upper surface is provided with buckle, it is possible to use
The bayonet socket that card lid inner surface wall is set, Jiang Kagai is fixed on fixed block, so as to protect the threaded connection post of fixed block side, made
Enhanced convenience must be placed, secondly by extension bar is provided with, the side of extension bar is provided with internal thread groove, it is possible to use screw thread
Connecting pole is threadedly secured in internal thread groove, during thereby using screw tap, it is possible to use extension bar is operated so that the screw tap is real
It is stronger with property, using enhanced convenience, then have to be provided with by extension bar surface and hold groove so that taking enhanced convenience, be difficult
Slide, operate enhanced convenience.
