The side surface of the booster rod 12 is provided with a sliding chamber 28 corresponding to the position below the storage convex strips 14, positioning cushion blocks 29 are symmetrically and equidistantly arranged in the sliding chamber 28, an extension rod 30 is slidably connected in the sliding chamber 28, positioning grooves 31 are formed in the positions, corresponding to the positioning cushion blocks 29, of the two side surfaces of the extension rod 30 at equal intervals, and one end of the extension rod 30 is glued with a limiting block 32.

The working principle and the using flow of the invention are as follows: when the multifunctional screwdriver convenient for replacing the screwdriver bit is used, firstly, the screwdriver bit 20 is selected according to a screw to be dismounted, then the storage hole 304 corresponding to the screwdriver bit 20 is checked through the label paper 9, then the rotating disc 6 is rotated through the matching action of the annular sliding plate 25 and the circular sliding groove 5, the position of the screwdriver bit outlet 7 is aligned with the storage hole 304 to be dismounted, then the rubber plug 8 is taken down, the screwdriver bit 20 is poured out from the storage hole 304 along the screwdriver bit outlet 7, and then the rubber plug 8 is plugged back into the screwdriver bit outlet 7 to wait for the next use;

after the cutter head 20 is taken out, one end of the cutter head 20 is plugged into the cutter head slot 19, the clamping cavities 21 are formed in two sides of the inside of the cutter head slot 19, the clamping springs 24 in the clamping cavities 21 push the clamping rubber plates 23 to squeeze the end parts of the cutter head 20, the cutter head 20 is primarily fixed, meanwhile, the bottom end of the cavity 2 is provided with the magnet 17, the cutter head 20 is attracted by the magnet 17 to be secondarily fixed, the stability of the cutter head 20 is improved, the condition that the cutter head 20 falls off in the using process is avoided, then the other end part of the cutter head 20 is inserted into a slot or a notch of a screw head, and then the handle 1 is turned to detach a screw;

when the handle 1 is rotated to disassemble the screw, the pressing cushion block 13 is pushed, the booster rod 12 swings towards the inside of the storage cavity 10 by taking the first rotating shaft 11 as the axis, so that the deformation of the pop-up spring 15 is increased, the deformation stress of the pop-up spring 15 is increased, the pressing cushion block 13 is suddenly released, the stress of the pop-up spring 15 recovering the deformation pushes the pop-up plate 16, the pop-up plate 16 pushes the booster rod 12, the storage convex strips 14 installed at the bottom end of the booster rod 12 are enabled to pass through the storage convex strips 14 installed at the bottom end of the storage cavity 10, the purpose of popping up the booster rod 12 is achieved, the force saving effect is achieved by a user holding the booster rod 12, after the booster rod 12 swings out, the force saving effect is difficult to achieve due to the fact that the force saving effect is short, the extension rod 30 is pulled out from the sliding cavity 28, the extension rod 30 is fixed after the extension rod 30 stretches out through the positioning cushion block 29, meanwhile, the user holds the extension rod 30 to exert the effect of optimizing effect, the limiting block 32 can avoid the situation that the extension rod 30 is difficult to take out due to excessive shrinkage, and the user is also convenient for pulling the extension rod 30 out through the limiting block 32;

after the use is finished, the booster rod 12 is swung by taking the first rotating shaft 11 as the axis, so that the booster rod 12 is retracted into the accommodating cavity 10, the accommodating raised strips 14 arranged at the bottom end of the booster rod 12 are clamped by the accommodating raised strips 14 arranged at the bottom end of the accommodating cavity 10, the booster rod 12 is accommodated and fixed, the deformation of the ejecting spring 15 is small, the deformation stress of the ejecting spring 15 is insufficient to push the accommodating raised strips 14 arranged at the bottom end of the booster rod 12 to cross the accommodating raised strips 14 arranged at the bottom end of the accommodating cavity 10, the effect of accommodating the booster rod 12 is achieved, then the rubber plug 8 is taken out from the cutter head outlet 7, the cutter head 20 is plugged back into the accommodating hole 304 to wait for the next taking, and then the stored cutter head 20 is prevented from falling through the cutter head outlet 7 when the rubber plug 8 is plugged back into the cutter head outlet 7;

when the screwdriver is carried, the size of the handle 1 is smaller, a user can put the screwdriver on a pocket to carry about, when the pocket is inconvenient to carry about, the fixing holes 2705 and the fixing buckles 2707 of the first fixing edge 2704 and the second fixing edge 2706 are separated, the first plastic strip 2702 and the second plastic strip 2703 are taken out, the first plastic strip 2702 and the second plastic strip 2703 are swung, the first plastic strip 2702 and the second plastic strip 2703 are fixed through the fixing holes 2705 and the fixing buckles 2707 again, the fixing blocks 2701 are matched to form a ring shape, the handle 1 is hung on the key buckle or the trousers waistband through the ring-shaped belt formed by the first plastic strip 2702 and the second plastic strip 2703, so that the screwdriver is more convenient to carry, meanwhile, the balancing weights 2709 and the placing planes in the grooves 2708 are attached to each other in the placing process, the center of gravity position is deviated from the center position of the handle 1, the handle 1 is prevented from shaking and losing, when the screwdriver is used, the first plastic strip 2702 and the second plastic strip 2703 are only required to be fixed through the fixing holes 2703, and the second plastic strip 2703 are not disturbed, and the handle 2703 can be fixed by the fixing the first plastic strip 2702 and the second plastic strip 2703.

Finally, it should be noted that: the foregoing is merely a preferred example of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments.
