Abstract
The utility model relates to a magnetic screwdriver which is characterized in that more than a piece of permanent-magnet alloy is enchased on the rod (2) of the screwdriver. The rod (2) of the screwdriver is injected with alni magnet powder. The utility model which has advantage of easy use, long magnetic holding time is especially suitable for repairing appliances and other precision instruments.
Description
The utility model relates to a kind of hand tools, relates in particular to a kind of magnetic screw driver.
Existing magnetic screw driver adopts and be packed with magnetic material in its handgrip, makes screwdriver rod have magnetic, thereby screw is held.But because this unreasonable structure, screwdriver rod is after using a period of time, and its magnetic can weaken and can not hold screw, does not reach the effect of magnetic screw driver.
The purpose of this utility model provides a kind of magnetic, and result of use is magnetic screw driver preferably.
The structure of this magnetic screw driver as shown in Figure 1.
This magnetic screw driver has handgrip (1), screwdriver rod (2), driver bit (3), it is characterized in that: one, be inlaid with the permanent-magnet alloy more than at least one on screwdriver rod (2); Two, screwdriver rod (2) lining has been cast into the alni magnet powder.Thereby make screwdriver rod (2) have permanent magnetic.When inlaying permanent-magnet alloy, should consider the working strength of screwdriver rod (2).Should consider also that simultaneously permanent magnetic alloy piece uses through long-term, magnetic reduces, the convenience that permanent magnetic alloy piece replaces with.Driver bit (3) can be flat in-line, also can be cross.When making this magnetic screw driver, the feature two of inlaying the feature one of permanent-magnet alloy and being cast into the alni magnet powder in screwdriver rod (2) lining can adopt simultaneously, also can adopt respectively.
This magnetic screw driver is simple in structure, and is easy to use, and the magnetic retention time is long, comparatively suitable to repairing household electrical appliances and other precision instrument.
Fig. 1 can be used as an embodiment schematic diagram of the present utility model.
