Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
Referring to Fig. 1, the embodiment of the present invention includes：
A kind of magnetic screw driver with the permanent magnet absorption expansion power-assisted body of rod, including screwdriver handle 1 and connector 2, the spiral shell
The front end of silk handle of a knife 1 connects the connector 2, and the upper surface of the connector 2, which is recessed inwardly, sets the screens of a regular hexagon
Slot 3, one piece of rare-earth permanent magnet 4 is bonded on the bottom face of the screens slot 3, and the side wall of the screwdriver handle 1 is equipped with several
The bottom face of driver bit slot 5, the driver bit slot 5 is equipped with permanent magnetic steel, the left and right sidewall of the screwdriver handle 1
Upper longitudinal direction sets two circular grooves 6, and the inside of the circular groove 6 sets two permanent magnet assister bars 7 of embedded placement, described
One end of permanent magnet assister bar 7 is equipped with raised connection screw thread, and the other end of the permanent magnet assister bar 7 sets indent connection screw thread,
Through an insertion hole 8 is set among the end of the screwdriver handle 1,8 bore of insertion hole is straight with the permanent magnet assister bar 7
Diameter is identical.
