Description
Technical field
The present invention relates to driver technology fields, and in particular to multifunctional screw driver.
Background technology
Screwdriver be for twisting screw to compel a kind of its specific purpose tool in place, can usually there are one thin sphenocephaly
It is inserted into the line of rabbet joint or recess of screw cap, but the cause not of uniform size in the line of rabbet joint of screw cap or recess, it so needs to make
With the screwdriver of different model or the multi-purpose screwdriver with Multiple Type driver bit, common how middle cutter head currently on the market
Screwdriver it is also very more, but it is most of driver bit is carried with other auxiliary tools using individual handle, it is and each
Replacing cutter head needs artificial manual replacement, cumbersome, so as to also reduce work efficiency.Also someone devises one kind therefore
The multifunctional screw driver of similar revolver, by placing the driver bit of different model in runner, using turning for runner
It is dynamic to switch over.But the multifunctional screw driver of this structure is using screw since driver bit and screwdriver handle are separated
Driver bit easily occurs during knife because firmly excessive, driver bit is caused to depart from from screwdriver handle, and switches screwdriver
It can also happen that clamping stagnation, is caused inconvenient for use during head.
Therefore, how existing multifunctional screw driver is improved is that urgently to be resolved hurrily one of those skilled in the art asks
Topic.
The content of the invention
It is a kind of rational in infrastructure it is a primary object of the present invention to provide, use reliable, the flexible more work(of driver bit switching
It can screwdriver.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of service-strong multifunctional screw driver, including
The pull end and rear lug being slidably socketed, the mandril being fixed in the rear lug, the runner being rotationally connected on the pull end, Yi Jifang
The driver bit of different model in the runner is placed in, the mandril can be slided by the pull end and the opposite of the rear lug,
The runner is sequentially passed through, the driver bit of different model is pushed to operating position；It is characterized in that：Before the pull end
End opens up the first hexagon ring, and the pull end rear end offers the first circular hole, and the runner front end offers connection the described 1st
Second hexagon ring of corner apertures, the runner rear end offer the second circular hole for connecting first circular hole, the driver bit bag
Include cutter head and hexagonal cylinder, the mandril in turn through first circular hole, second circular hole, second hexagon ring and
First hexagon ring；First hexagon ring is identical with the cross sectional shape of second hexagon ring, first circular hole and institute
State that the cross sectional shape of the second circular hole is identical, the inscribed circle diameter of first hexagon ring and second hexagon ring is not less than described
The internal diameter of first circular hole and second circular hole, first hexagon ring and second hexagon ring are complete both in same axis
Full weight is closed, and the hexagonal cylinder is overlapped with the inner wall of first hexagon ring and second hexagon ring, realizes the screwdriver
Head can only carry out straight-line displacement along first hexagon ring and the axial of second hexagon ring.By said structure, needing
When switching driver bit.Driver bit can be promoted from the second hexagonal by mandril through the first circular hole and the second circular hole
Hole enters the first hexagon ring, until reaching operating position, cannot rotate in the first hexagon ring internal thread cutter head, using more
Reliably, driver bit switching is flexibly also very convenient.
Preferably, the mandril is overlapped with the inner wall of first circular hole and second circular hole.The structure makes pull end
It is more firm to be connected with rear lug, will not shake, use is relatively reliable.
Compared with prior art, the advantage of the invention is that：It can be pushed away by mandril through the first circular hole and the second circular hole
Dynamic driver bit is from the second hexagon ring into the first hexagon ring, until operating position is reached, in the first hexagon ring internal thread cutter head
It cannot rotate, use is relatively reliable, and driver bit switching is flexibly also very convenient.

Specific embodiment
It is described below to disclose the present invention so that those skilled in the art can realize the present invention.It is excellent in being described below
Embodiment is selected to be only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
As shown in Fig. 1~10, one embodiment of the present of invention includes the pull end 1 being slidably socketed and rear lug 2, is fixed in rear lug
Mandril 3 on 2, the runner 4 being rotationally connected on pull end 1 and the driver bit 5 for being positioned over different model in runner 4.Its work
It is as follows to make principle：Mandril 3 can be slided by pull end 1 and the opposite of rear lug 2, runner 4 be sequentially passed through, by the screwdriver of different model
First 5 are pushed to operating position.
It is critical that 1 end opens up the first hexagon ring 11 before pull end, 1 rear end of pull end offers the first circular hole 12, runner
4 front ends offer the second hexagon ring 41 of the first hexagon ring 11 of connection, and 4 rear end of runner offers the second of the first circular hole 12 of connection
Circular hole 42, driver bit 5 include cutter head 52 and hexagonal cylinder 51, mandril 3 in turn through the first circular hole 12, the second circular hole 42,
Second hexagon ring 41 and the first hexagon ring 11；First hexagon ring 11 is identical with the cross sectional shape of the second hexagon ring 41, the first circular hole
12 is identical with the cross sectional shape of the second circular hole 42, and the inscribed circle diameter of the first hexagon ring 11 and the second hexagon ring 41 is not less than first
The internal diameter of 12 and second circular hole 42 of circular hole, the first hexagon ring 11 and the second hexagon ring 41 are completely superposed both in same axis,
Hexagonal cylinder 52 is overlapped with the inner wall of the first hexagon ring 11 and the second hexagon ring 41, realizes that driver bit 5 can only be along the first hexagonal
The axial of 11 and second hexagon ring 41 of hole carries out straight-line displacement.Mandril 3 is overlapped with the inner wall of the first circular hole 12 and the second circular hole 42.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
