Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
It please refers to shown in Fig. 1-6, Multifunctional combined screw-driver, including shell 1, screwdriver rod 2, fastener head 3.On shell 1
End is equipped with knob 4, the carrying that knob 4 can facilitate the present apparatus, secondly, knob 4 can be rotated around shell, when the present apparatus being facilitated to work pair
Shell 1 applies thrust.1 lower end of shell is equipped with opening 5, and opening 5 is used for the stretching of screwdriver rod 2.1 outer wall of shell is equipped with card slot
6, the quantity of card slot 6 is identical as the quantity of screwdriver rod 2.Limited block 7 is fixed on 1 inner wall of shell, limited block 7 is by multiple arcs
Face composition, the quantity of arcwall face is identical as 6 quantity of card slot, and arcwall face is oppositely arranged with card slot 6, and limited block 7 is arranged in card slot 6 one
Side, there are certain spaces between limited block 7 and card slot 6.Button 8,8 one end of button point are respectively equipped between card slot 6 and limited block 7
Shell 1 is not stretched out from card slot 6,8 other end of button is fixedly connected with screwdriver rod 2, and button 8 can carry out moving down in card slot 6
It is dynamic.In shell 1 and it is located at below limited block 7 equipped with disk 9, disk 9 is equipped with perforation 10, and 2 lower end of screwdriver rod is each passed through
