Description
Technical field
The present invention relates to driver technology field, and in particular to multifunctional screw driver.
Background technology
Screwdriver is that usually have a thin sphenocephaly for twisting screw to compel a kind of its specific purpose tool in place, can
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, 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 currently on the market
Screwdriver it is also very more, but it is most of driver bit is carried with other auxiliary tools using single handle, and every time
Replacing cutter head needs artificial manual replacement, cumbersome, so as to also reduce work efficiency.Also someone devises one kind for this
The multifunctional screw driver of similar revolver, turns by placing the driver bit of different model in runner, then by runner
It is dynamic to switch over.But there is dismounting inconvenience in the runner of the multifunctional screw driver of this structure, and be easy to cause screwdriver after dismantling
Head drops loss.
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 convenient for disassembly and assembly it is a primary object of the present invention to provide a kind of runner, and driver bit is stored reliably in runner
Improved multifunctional screw driver.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of improved multifunctional screw driver, including slide
The pull end and rear lug of socket, the mandril being fixed in the rear lug, the runner being rotationally connected with the pull end, and be positioned over
The driver bit of different model in the runner, the mandril can be slided by the pull end and the opposite of the rear lug, successively
Through the runner, the driver bit of different model is pushed to operating position；It is characterized in that：The runner includes turning
Wheel body, card bead, spring and magnetic substance, the card bead is two, and the card bead is slidably arranged in the web both ends,
The spring is arranged between two card beads, and the magnetic substance is arranged in the web, and the magnetic substance and institute
State attractive between driver bit.By said structure, one side card bead can act on runner by the elastic force of spring
Stretch on body, facilitate the disassembly and installation of runner；The setting of another aspect magnetic substance ensures that driver bit cannot be in runner
It is interior arbitrarily mobile, also ensure after runner disassembles, driver bit will not drop loss easily.
Preferably, offering the elastic cavity for accommodating the card bead and the spring in the web, and accommodate institute
The magnetic chamber of magnetic substance is stated, the web is provided at both ends with the snap ring for limiting the card bead sliding position；The card bead includes
Orbicule, torus and cylinder, the orbicule is located on the outside of the snap ring, and the orbicule outside diameter is not more than the card
Ring internal diameter, the torus are located on the inside of the snap ring, and the torus outside diameter is more than the snap ring internal diameter, and the spring connects
It is connected on the outside of the cylinder.Above-mentioned is a kind of preferred structure, simple and effective can realize the flexible of card column, and reasonably
Place magnetic substance.
Compared with prior art, the advantage of the invention is that：One side card bead can be acted on by the elastic force of spring to be turned
Stretch on wheel body, facilitate the disassembly and installation of runner；The setting of another aspect magnetic substance ensures that driver bit cannot turn
Arbitrarily move in wheel, also ensure after runner disassembles, driver bit will not drop loss easily.

Embodiment
It is described below for disclosing 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. 1~9, 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 mandril 3, the runner 4 being rotationally connected with pull end 1, and be positioned over the driver bit 5 of 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.Itself it is critical that, runner 4 includes web 41, card bead 42, spring 43 and magnetic substance 44, institute
Card bead 42 is stated as two, and the card bead 42 is slidably arranged in 41 both ends of web, the spring 43 is arranged on two
Between a card bead 42, the magnetic substance 44 is arranged in the web 41, and the magnetic substance 41 and the screwdriver
