Description
Technical field
The present invention relates to driver technology field, and in particular to multifunctional screw driver.
Background technology
Screwdriver is that generally have a thin sphenocephaly for twisting screw to compel a kind of its specific purpose tool in place, can
Insert in 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, so need to make
With the screwdriver of different model or the multi-purpose screwdriver with Multiple Type driver bit, common how middle cutter head in the market
Screwdriver it is also very more, but it is most of driver bit is carried with other aids using single handle, and every time
Changing cutter head needs artificial manual replacing, cumbersome, so as to also reduce operating efficiency.For this, also someone devises one kind
The multifunctional screw driver of similar revolver, turn by placing the driver bit of different model in runner, then by runner
It is dynamic to switch over.But the multifunctional screw driver of this structure still must be observed by the naked eye push rod when cutter head is switched
, the problem of cutter head switching is inconvenient be present in the corresponding driver bit of alignment.
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 primary object of the present invention to provide a kind of runner conveniently to stir, and runner has the cutter head switching side of shift feeling
Just multifunctional screw driver.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of multifunctional screw driver of cutter head easy switching,
Including the pull end being slidably socketed and rear lug, the push rod being fixed in the rear lug, the runner being rotationally connected with the pull end, with
And the driver bit of different model in the runner is positioned over, the push rod can pass through the relatively sliding of the pull end and the rear lug
It is dynamic, the runner is sequentially passed through, the driver bit of different model is pushed to operating position；It is characterized in that：It is described more
Function screwdriver also includes gear block, and the gear block contacts the runner, for limiting the turned position of the runner；It is described
Runner is provided at both ends with elastic card bead, and the circular neck coordinated with the elastic card bead, the runner are provided with the pull end
On be additionally provided with that a circle opens up vertically stir groove.The setting of gear block can realize accurately switching driver bit；Elasticity
The setting of card bead and circular neck can facilitate runner to be rotated on pull end, and be separated from pull end；The setting for stirring groove can
Runner is more easily stirred to realize.
Preferably, the gear block is provided with elastic bumps, arc groove circumferentially is provided with the runner, often
The individual corresponding driver bit of the arc groove, when the elastic bumps enter the arc groove, the push rod can
Through the runner.When rotating wheel, when arc groove contact resilient is raised, have obvious shift feeling, without
Push rod can be directed at a driver bit in the case of visually observing, realize the switching of driver bit.
Preferably, the arc groove is six, and the corresponding driver bit is six.The setting of six can meet
Daily use demand.
Compared with prior art, the advantage of the invention is that：On the one hand, the setting of gear block can realize accurate switching
Driver bit；The setting of elastic card bead and circular neck can facilitate runner to be rotated on pull end, and be separated from pull end；Dial
The setting of dynamic groove, which can be realized, more easily stirs runner.On the other hand, when rotating wheel, when arc groove contacts
Elastic bumps, obvious shift feeling is had, push rod can be aligned to a driver bit in the case of without visually observing, it is real
The switching of existing driver bit, makes runner have shift feeling.

Embodiment
Describe to be used to disclose the present invention below so that those skilled in the art can realize the present invention.It is excellent in describing 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. 1~8, one embodiment of the present of invention includes pull end 1 and the rear lug 2 being slidably socketed, and is fixed in rear lug 2
On push rod 3, the runner 4 being rotationally connected with pull end 1, and be positioned over different model in runner 4 driver bit 5 and set
In the gear block 6 of pull end 1.Its operation principle is as follows：Push rod 3 can be sequentially passed through and turned by the relative slip of pull end 1 and rear lug 2
Wheel 4, the driver bit 5 of different model is pushed to operating position, gear block 6 contacts runner 4, for limiting the rotation of runner 4
Position.
