Description

A kind of combined type multiple bit screwdriver

[technical field]

The utility model relates to a kind of screwdriver, is specifically related to a kind of combined type multiple bit screwdriver.

[background technology]

In the prior art, a screwdriver only is equipped with a cutter head usually, yet in actual applications, the specification of screw may have multiple, therefore, if adopt traditional screwdriver, during use, may need once to carry many requirements that could meet screwdriver use, this brings great inconvenience to use, has also increased the cost of instrument simultaneously.

Chinese utility model patent 201120528272.0 discloses a kind of replaceable head screwdriver, comprises screwdriver handle, screwdriver rod, driver bit and magnetic block; By the magnetic block that is arranged on the screwdriver rod front end, hold driver bit, screwdriver rod and driver bit are all squares, the phenomenon of spinning need not occur during use, while changing driver bit, the lid of outwarding winding on screwdriver handle and having, therefrom take out the driver bit that will change; This screwdriver structure is simple, easy to use, promotes easily.Yet still there is following defect in this replaceable head screwdriver: 1, cutter head is positioned over handle of a knife inside mussily, while changing cutter head, may need to take out all cutter heads and just can find the cutter head of needs, use and still have greatly inconvenience; 2, screwdriver rod adopts the square structure, and mechanical property is not good and manufacture difficulty is larger.

For the problems referred to above, be necessary to develop a kind of combined type multiple bit screwdriver, make it possess simultaneously a plurality of cutter heads that can change, and cutter head deposit in good orderly, easy to use, reduced simultaneously the cost of instrument.

[summary of the invention]

The utility model discloses a kind of combined type multiple bit screwdriver, it possesses a plurality of cutter heads that can change simultaneously, and cutter head deposits in good orderly, easy to use, has reduced simultaneously the cost of instrument.

The technical solution of the utility model is as follows:

A kind of combined type multiple bit screwdriver, comprise handle, pedestal, knife bar and a plurality of cutter head; One end of described knife bar is fixed on pedestal, and the other end of knife bar is provided with for fixing the first fixed groove of cutter head; The end face of the end that pedestal is connected with knife bar is provided with a plurality of be used to depositing the second fixed groove of cutter head, and the afterbody of cutter head is provided with the plush copper corresponding with the first fixed groove and the second fixed groove.

Combined type multiple bit screwdriver of the present utility model possesses a plurality of cutter heads that can change simultaneously, the first fixed groove is for the steady job cutter head, and all the other cutter heads are deposited and are fixed in the second fixed groove, and cutter head is deposited in good order, easy to use, reduced simultaneously the cost of instrument.

[accompanying drawing explanation]

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the decomposition view of Fig. 1.

[specific embodiment]

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.

As shown in Figure 1 to Figure 2, combined type multiple bit screwdriver of the present utility model comprises handle 1, pedestal 3, knife bar 6 and a plurality of cutter head 5; One end of knife bar 6 is fixed on pedestal 3, and the other end of knife bar 6 is provided with the first fixed groove 7 for the steady job cutter head; The end face of the end that pedestal 3 is connected with knife bar 6 is provided with a plurality of be used to depositing the second fixed groove 4 of cutter head 5, and the afterbody of cutter head 5 is provided with the plush copper 8 corresponding with the first fixed groove 7 and the second fixed groove 4.

Preferably, the second fixed groove 4 be distributed on knife bar 6 around, untapped like this cutter head 5 can be deposited regularly and be fixed in the second fixed groove 4 by the difference of specification, thus while need changing cutter head, can find more easily the cutter head needed, increase work efficiency;

Preferably, cutter head 5 adopts permanent-magnet material to make, and knife bar 6 adopts magnetic material to make, and cutter head 5 is fixed in the first fixed groove on knife bar 6 in the mode of magnetic absorption, is that the installation and removal of cutter head 5 are convenient;

Preferably, the first fixed groove 7 and the second fixed groove 4 be shaped as square, make the transmission of moment of torsion even;

Preferably, the outside of handle 1 is provided with a plurality of anti-slip tanks 2, the transmission of moment of torsion while using with assurance.

Above-described embodiment of the present invention, do not form the restriction to protection domain of the present invention.Any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present invention.
