Detailed description of the invention
Fig. 1 is monnolithic case structural schematic diagram of the present invention；
Fig. 2 is the schematic diagram of internal structure of screwdriver head of the present invention；
In figure: 1- driver bit handle, 2- screwdriver head, 3- anti-collision rubber, 4- unit of plastic, 5- level-one magnetic force magnet, 6- modeling
Expect jube, 7- plastic drive bar, 8- second level magnetic force magnet, 9- chrome alum alloy trigone cutter head.
Specific embodiment
Below in conjunction with Figure of description, the invention will be further described.
As shown in Figs. 1-2, a kind of magnet-type multifunctional screw driver, including driver bit handle 1, screwdriver head 2, anticollision
Rubber 3, unit of plastic 4, level-one magnetic force magnet 5, plastics jube 6, plastic drive bar 7, second level magnetic force magnet 8 and chrome alum alloy trigone
Cutter head 9.
Screwdriver head 2 is arranged on driver bit handle 1, and modeling is fixedly installed in the bosom position of screwdriver head 2
Expect that jube 6, plastics jube 6 are equipped with a component separate space, the level-one magnetic force magnet 5 is closely matched and arranged inside in compartment.One
Unit of plastic 4 is equipped at the top of grade magnetic force magnet 5,2 top position of screwdriver head is equipped with anti-collision rubber 3, the anti-collision rubber 3 and modeling
Expect to be equipped with movement clearance between block 4, anti-collision rubber 3 can carry out unit of plastic 4 effect of sports limiting and buffering；Level-one magnetic force
It is equipped with installation through-hole inside magnet 5, plastic drive bar 7 is fixedly installed on unit of plastic 4, plastic drive bar 7 passes through level-one magnetic force magnetic
Simultaneously second level magnetic force magnet 8, level-one magnetic force magnet 5 and second level magnetic force magnet 8 is fixedly installed in its bottom in installation through-hole inside iron 5
Magnetism on the contrary, on second level magnetic force magnet 8 be fixedly installed chrome alum alloy trigone cutter head 9.
Chrome alum alloy trigone cutter head 9 is arranged in pairs, and a pair of of chrome alum alloy trigone cutter head 9 is spliced to form small quadrangle knot
Structure；Screwdriver head 2 uses cylindrical structure, and the chrome alum alloy trigone cutter head 9 is tightly packed in screwdriver head 2, and structure
At big quadrilateral structure；Driver bit handle 1 uses cylindrical structure, and its size is greater than 2 size of screwdriver head.
Chrome alum alloy trigone cutter head 9 be arranged in screwdriver head 2, and it is concordant with 2 end of screwdriver head be arranged, prevent
Chrome alum alloy trigone cutter head 9 avoids the favorite outer scuffing of use process outside being exposed to.
The size of unit of plastic 4 is greater than the size of 5 inside installation through-hole of level-one magnetic force magnet, prevents unit of plastic 4 from falling to peace
It fills in through-hole, causes the missing of chrome alum alloy trigone cutter head.
What the screwdriver was utilized that same sex magnet repels each other can change alloy three automatic restorative the characteristics of shortening with stress
Rib cutter block combined shaped realizes the Auto-matching of multiple types screw, and one is pressed onto the function of the direct rotary screw of screw surface, even
Correct step can be omitted.Screwdriver head is many chrome alum alloy trigone cutter heads, they directly contact screw head, is being squeezed
After pressure encounters screw surface, vanadium alloy trigone column cap receding, the difference of height of screw surface leads to middle section chrome alum alloy three
Rib cutter head is embedded in screw surface hole location, so that screwdriver changes shape automatically.This sequence of operations is all every by connecting
A chrome alum alloy trigone cutter head is hidden in the second level magnetic force magnet in the drive rod transmitting pressure to screwdriver head of screwdriver head,
Second level magnetic force magnet is also different because of the length that the difference of front end difference of height is extruded.
Application method:
The screwdriver is directed at screw head, after slightly firmly making in screw head insertion chrome alum alloy trigone cutter head to screw direction
It can screw or unscrew.
The product is very suitable to family, each place for needing to use screw of factory uses.Because of its automatic Scheduling Matching
By force, it is possible to greatly reduce the trouble for carrying multiple screws knife, can replace more screws such as hexagonal, triangle, star
The various occasions for needing Special screw driver of shape ... can be used.
