Abstract
The utility model relates to a hardware tool, namely a screwdriver with nut and bolt assembling and disassembling function. The screwdriver is formed by sequentially connecting a screwdriver handle (1), a connecting part (2) and a screwdriver head (3). The screwdriver is characterized in that: the connecting part is in a regular four-edge shape; four lateral surfaces, which are not connected with the screwdriver handle (1) with nut and bolt assembling and disassembling function and the screwdriver head (3) with nut and bolt assembling and disassembling function, of the connecting part are provided with a six-prism depression (4) respectively; the diameters of the six-prism depressions (4) are different; a through hole (5) is formed between the six-prism depressions of two opposite lateral surfaces; and the screwdriver head (3) with nut and bolt assembling and disassembling function is integrated with the connecting part (2) by casting or welding. Through the six-prism depressions and the through holes in the four lateral surfaces of the connecting part of the screwdriver, the function of assembling and disassembling nuts and bolts besides screws and the function of increasing the torque are realized; and the screwdriver has strong practicability, and is a novel screwdriver with nut and bolt assembling and disassembling function and with popularization value.
Description
Technical field
The present invention relates to a kind of screwdriver, especially a kind of screwdriver that loads and unloads the nut bolt function.
Background technology
The screwdriver that has multiple fastening installation or removal nut to use in the market although model is numerous, all has function singleness, shortcomings such as moment of torsion is less than normal, for being difficult to dismantle or fastening parts are difficult for smooth dismounting, the user also often needs the instrument with multiple model, causes inconvenience to the user.
Summary of the invention
The present invention promptly is that a kind of novel multi-use that designs at the problem of prior art existence can load and unload the screwdriver of nut bolt function, it has characteristics such as the many moments of function are big, promptly except that loading and unloading the screw, also dismantled and assembled bolt or nut, by spanner or strongly can increase moment of torsion greatly, practical, wide application is a kind of novel screwdriver that loads and unloads the nut bolt function with promotional value.
1, coupling part 2 is connected in sequence with the crewdriver attachment that can load and unload the nut bolt function by the screwdriver that can load and unload the nut bolt function in the present invention.Coupling part 2 is the four-prism shape, its do not connect can load and unload the nut bolt function screwdriver 1, can load and unload on four sides of crewdriver attachment 3 of nut bolt function and respectively have a hexagon depression 4, each hexagon 4 diameters that cave in are all inequality, deposit the through hole 5 that has perforation between the hexagon depression 4 of two opposite flanks.The crewdriver attachment 3 that can load and unload the nut bolt function is one with coupling part casting or weldering.Can load and unload the crewdriver attachment shape of the mouth as one speaks of nut bolt function does not limit.
Tighten or loosen screw with the crewdriver attachment 3 that can load and unload the nut bolt function when the present invention uses, when running into very fastening or during the screw that is difficult to dismantle, can increase moment with strong insertion through hole 5 or with the coupling part 2 that spanner blocks square.When running into bolt or nut, select six prismatics depression, the 4 card column bolt or the nuts of suitable size, promptly can very big moment tighten or unclamp operation.
Description of drawings
Fig. 1 is overall structure figure of the present invention;
Fig. 2 is a coupling part A-A face cutaway view;
1 is the screwdriver handle that can load and unload the nut bolt function among the figure, the 2nd, and coupling part, the 3rd, crewdriver attachment, the 4th, hexagon depression, the 5th, through hole.
The specific embodiment
1, coupling part 2 is connected in sequence with the crewdriver attachment that can load and unload the nut bolt function by the screwdriver that can load and unload the nut bolt function in the present invention.Coupling part 2 is the four-prism shape, its do not connect can load and unload the nut bolt function screwdriver 1, can load and unload on four sides of crewdriver attachment 3 of nut bolt function and respectively have a hexagon depression 4, each hexagon 4 diameters that cave in are all inequality, deposit the through hole 5 that has perforation between the hexagon depression 4 of two opposite flanks.The crewdriver attachment 3 that can load and unload the nut bolt function is one with coupling part casting or weldering.Can load and unload the crewdriver attachment shape of the mouth as one speaks of nut bolt function does not limit.
Tighten or loosen screw with the crewdriver attachment 3 that can load and unload the nut bolt function when the present invention uses, when running into very fastening or during the screw that is difficult to dismantle, can increase moment with strong insertion through hole 5 or with the coupling part 2 that spanner blocks square.When running into bolt or nut, select six prismatics depression, the 4 card column bolt or the nuts of suitable size, promptly can very big moment tighten or unclamp operation.
Claims (1)
