It inside slides up and down, and since the presence of slideway and rotating block makes core bar screw can be driven to rotate, by being applied to core bar top
Torsion achieve the purpose that rotation, turn screw.
3, magnet is set at the top of slide post, if at the top of screw terminal screw groove damage or twist spend after can not extract screw,
Core bar room can be sucked out in core bar with magnetic driver bit or magnet at this time, it is easy to operate.
4, card slot is arranged in slide post top, and the card slot is polygon cyclic annular or strip, and stem is by driver bit or magnet
After suction, spanner can block card slot conveniently to rotate core bar and screw is driven to rotate.
5, the length of the core bar is greater than the length of core cylinder, guarantees that core cylinder can be smoothly sucked out in core bar top.
6, core cylinder top also sets up dust plug, and the dust plug is made of rubber, prevents muddy water from blocking core cylinder, and energy
Prevent core cylinder internal corrosion.
7, the core cylinder is Polygonal barrel, and core bar is corresponding gengon shape, and spanner, which can also be directly clamped among on core bar, to be turned
It is dynamic, to turn screw.
