When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.
Furthermore, the terms "long", "short", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships illustrated in the drawings, and are only for convenience of describing the present invention, but do not indicate or imply that the device or element referred to must have the specific orientation, operate in the specific orientation configuration, and thus, should not be construed as limiting the present invention.
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Example one
Referring to fig. 1 to 3, an embodiment of the present invention provides a magnetic adjustable screwdriver, including a screwdriver rod 1, a screwdriver handle 2, two semi-annular permanent magnets 3 with the same structure, and two control handles 4 with the same structure corresponding to the semi-annular permanent magnets 3; wherein the content of the first and second substances,
the cutter bar 1 is arranged inside the cutter handle 2, and two shaft seats are symmetrically arranged at one end, close to the cutter bar 1, of the cutter handle 2;
the control handle 4 comprises a fixed part 41 and a movable part 42;
one end of the movable part 42 is connected to the shaft seat 43 through a connecting shaft and one end of the fixed part 41, and the movable part 42 can move around the connecting shaft, so that the semi-annular permanent magnet 3 fixedly connected to the other end of the fixed part 41 is driven to be close to or far away from the cutter bar 1, and the cutter bar 1 is magnetized or demagnetized.
