Description

A kind of multiple bit screwdriver

Technical field

The present invention relates to a kind of screwdriver, particularly be a kind of multiple bit screwdriver, belong to the screwdriver technical field.

Background technology

Screwdriver is a kind ofly to be used for twisting screw to force its instrument in place.Present employed screwdriver majority is a fixed structure, have bar awl to have only a driver bit, also has bar awl that a plurality of driver bits are arranged.Bar awl have only a driver bit screwdriver its can only open a kind of screw of model, can not satisfy requirements of one's work; Its structure of screwdriver that bar awl has a plurality of driver bits is more complicated often, and the driver bit that handlebar need be changed is fixed on the handle, and the box of depositing driver bit that separate use with the screwdriver body is separately also arranged; Be to adopt to screw the driver bit of required transposing down basically when the transposing driver bit; Screw up the new required driver bit of using then and realize; In the process of using; The transposing of driver bit is a bit complicated, and the driver bit under being easy to change institute falls to loss; The present screwdriver that adopts has no additional function to screw simultaneously, and owing to the size of screw itself, it is taken and collects is not very convenient in work.

Summary of the invention

Technical problem to above-mentioned existence the objective of the invention is: proposed the multiple bit screwdriver that the driver bit under the transposing was changed conveniently and should not be lost to a kind of driver bit.

Technical solution of the present invention is achieved in that a kind of multiple bit screwdriver, comprises handle of a knife, driver bit assembly and cutter lid, and said handle of a knife middle part has manhole; Be provided with a plurality of driver bit assemblies in the said manhole; Said driver bit assembly comprises cutter head and knife bar; Be provided with hollow bulb in the said knife bar; Said cutter head can place in the hollow bulb; Said arbitrary cutter head stretches out handle of a knife; The bottom of said handle of a knife is provided with magnet piece; The top of said handle of a knife is through the cutter lid that has been threaded; Be provided with protruding block in the said manhole; Said knife bar is provided with the groove that is complementary with protruding block.

Preferably, be arranged with two protruding blocks in the said manhole.

Preferably, said magnet piece is identical with the external diameter of cutter lid; Said handle of a knife peripheral hardware rubber sleeve; The external diameter of said rubber sleeve equals the external diameter of magnet piece and cutter lid.

Preferably, the diameter of said cutter head equals the diameter of knife bar hollow bulb; The length of said cutter head is less than the degree of depth of knife bar hollow bulb.

Preferably, said cutter head assembly is provided with three, is yi word pattern cutter head assembly, cross cutter head assembly and blossom type cutter head assembly.

Because the utilization of technique scheme, the present invention compared with prior art has advantage:

Multiple bit screwdriver of the present invention, in the process of using, the words of changing the driver bit assembly if desired; Can pull up the driver bit assembly of being worked come; Screw off cutter lid, insert its top, its cutter head is placed in the hollow bulb of knife bar of another driver bit assembly in the handle of a knife from handle of a knife; Repeat above-mentioned steps as required until the needed driver bit assembly of transposing cutter; The cutter of screwing at last lid, it is extremely convenient to change driver bit, and the situation that can fundamentally avoid losing the driver bit under the transposing takes place; Simultaneously can hold screw, be convenient to taking and collecting like this screw with magnet piece.

Description of drawings

Below in conjunction with accompanying drawing technical scheme of the present invention is described further:

Accompanying drawing 1 is the stereogram of multiple bit screwdriver of the present invention;

Accompanying drawing 2 is the structural representation of multiple bit screwdriver of the present invention;

Wherein: 1, handle of a knife; 2, manhole; 3, cutter head; 4, knife bar; 5, hollow bulb; 6, magnet piece; 7, cutter lid; 8, protruding block; 9, rubber sleeve; 10, groove.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described.

Like accompanying drawing 1, the of the present invention a kind of multiple bit screwdriver shown in 2, comprise handle of a knife 1, driver bit assembly and cutter lid 7; The middle part of said handle of a knife 1 has manhole 2; Be provided with three driver bit assemblies in the said manhole 2, be respectively yi word pattern cutter head assembly, cross cutter head assembly and blossom type cutter head assembly; Said driver bit assembly comprises cutter head 3 and knife bar 4; Be provided with hollow bulb 5 in the said knife bar 4; The diameter of said cutter head 3 equals the diameter of knife bar 4 hollow bulbs 5; The length of said cutter head 3 is less than the degree of depth of knife bar 4 hollow bulbs 5; Said cutter head 3 can place in the hollow bulb 5; Said arbitrary cutter head 3 stretches out handle of a knife 1; The bottom of said handle of a knife 1 is provided with magnet piece 6; The top of said handle of a knife 1 is through the cutter lid 7 that has been threaded; Be provided with two protruding blocks 8 of symmetry in the said manhole 2; Said knife bar 4 is provided with the groove 10 that is complementary with protruding block 8; Said handle of a knife 1 peripheral hardware rubber sleeve 9; The external diameter of said magnet piece 6, cutter lid 7 and rubber sleeve 9 is mutually the same.

In the process of using, because cutter head assembly upwards has cutter lid 7 to withstand, the magnet piece 6 that has handle of a knife 1 bottom to be provided with downwards holds, and the groove 10 of knife bar 4 is blocked and then realize the function of screwdriver when screwing by the protruding block 8 that is provided with in handle of a knife 1 manhole 2; Can hold with magnet piece 6 and take again after the screw and collect screwing the screw that gets off simultaneously, use more convenient like this; Change the words of driver bit assembly if desired; Can cover 7 to cutter screws; The driver bit assembly of working with handgrip is pulled out, and inserts the cutter head 3 of the driver bit assembly of being pulled out in the hollow bulb 5 of knife bar 4 of another driver bit assembly in the handles 1, by that analogy from the top of handle of a knife 1 then; Till finding suitable driver bit assembly, screw cutter lid 7 at last and just can realize changing the function of cutter head assembly; The present invention is simple in structure, and transposing driver bit assembly is convenient, and the situation that can fundamentally avoid losing the driver bit assembly under the transposing takes place.

The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
