Description
Technical field
The present invention relates to component of machine technical field, in particular to a kind of biography of the adjustable electric screw driver of cutter head angle
Dynamic device.
Background technology
Screwdriver is used for make use of the operation principle of wheel shaft when the turn of the screw is followed closely, in order to apply little torsion to minus screw
Away from it is thought that opening a bar groove on head of screw, can easily just being tightened with corresponding Flathead screwdriver and unclamp screw
, but with the rapid development of science and technology, the application of screw is more and more extensive, and the deficiency of screw and straight screwdriver is also in
Reveal and.Be first head of screw flat recess once destroyed, screw can not just be back-outed.The length of flat recess is longer,
It is easier to be destroyed during being screwed.In order to shorten the length of notch, the ability that notch resistance destroys, and can are improved
An equal amount of torsion is transmitted, it is thought that with cross recess, same torsion can be born, but the length of a notch is short
Half, the ability for resisting destruction but greatly strengthen.
Now, in order to reduce labor intensity, electric screw driver is increasingly popularized, still, the same with common manual screwdriver,
When nearby having foreign object stop in the top of the groove of screw, the edge of a knife of screwdriver can not be made completely into the groove of screw
Can not transmit torque into screwdriver can not work to screw, screwdriver.
