The utility model content
The utility model purpose is the multiple bit screwdriver that provides a kind of driver bit transposing in order to overcome the deficiencies in the prior art conveniently and should not lose the driver bit under the transposing.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multiple bit screwdriver, comprise handle of a knife, driver bit assembly and cutter lid, and described handle of a knife middle part has manhole; Be provided with a plurality of driver bit assemblies in the described manhole; Described driver bit assembly comprises cutter head and knife bar; Be provided with hollow bulb in the described knife bar; Described cutter head can place in the hollow bulb; Described arbitrary cutter head stretches out handle of a knife; The bottom of described handle of a knife is provided with magnet piece; The top of described handle of a knife has been threaded connection the cutter lid; Be provided with protruding block in the described manhole; Described knife bar is provided with the groove that is complementary with protruding block.
Preferably, be arranged with two protruding blocks in the described manhole.
Preferably, described magnet piece is identical with the external diameter of cutter lid; Described handle of a knife peripheral hardware rubber sleeve; The external diameter of described rubber sleeve equals the external diameter of magnet piece and cutter lid.
Preferably, the diameter of described cutter head equals the diameter of knife bar hollow bulb; The length of described cutter head is less than the degree of depth of knife bar hollow bulb.
Preferably, described 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 utility model compared with prior art has following advantages:
Multiple bit screwdriver of the present utility model, in the process of using, if need transposing driver bit assembly, can pull up the driver bit assembly of working come, screw off the cutter lid, its top from handle of a knife is inserted, its cutter head is placed in the hollow bulb of knife bar of another driver bit assembly in the handle of a knife, repeat above-mentioned steps as required until the needed driver bit assembly of transposing cutter, screw at last the cutter lid, it is extremely convenient to change driver bit, and the situation that can fundamentally avoid losing the driver bit under the transposing occurs; Simultaneously can hold screw with magnet piece, be convenient to like this taking and collecting screw.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the stereogram of multiple bit screwdriver of the present utility model;
Accompanying drawing 2 is the structural representation of multiple bit screwdriver of the present utility model;
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.
