Abstract

The utility model discloses a combined screw driver with multiple tool bits. The combined screw driver comprises tool holders, the tool bits and tool bars, wherein both the tool bars and the tool holders are cylindrical, the tool bars are connected onto the tool holders, the tool holders include two sections which are in threaded connection, the tool bars which are in hinged connection with three slotted tool bits are uniformly distributed on one section of the tool holder, the tool bars which are in hinged connection with three cross-shaped tool bits are uniformly distributed on the other section of the tool holder, and the tool holders can rotate by 90 degrees, so that the tool bars can be in a vertical state with the tool holders. According to the combined screw driver with multiple tool bits, the troublesome of selecting suitable tool bits of the screw driver is reduced, one screw driver can use both the slotted tool bits and the cross-shaped tool bits, and the sizes of the tool bits suitable for screws can be selected, so that the working efficiency is greatly improved, and the combined screw driver with the multiple tool bits is simple in structure, low in cost and convenient in use and carrying.

Description

The combination screw driver of a kind of bull

Technical field

The utility model relates to a kind of instrument, particularly a kind of combination screw driver.

Background technology

The screwdriver that has a lot of models to differ in present tool box, when carrying out flight-line maintenance, usually can be because of the screwdriver that can not find or seek different cutter heads worry, also reduced the operating efficiency of flight-line maintenance.Be equipped with a lot of screwdrivers in a lot of tool boxes although have at present, carried after all so many screwdriver very inconvenient.One has a plurality of cutter heads, and screwdriver easy to carry, as to take full advantage of its structural behaviour is more rare at present.

The utility model content

Technical problem to be solved in the utility model is to provide the combination screw driver of bull, solves the problem that existing screwdriver only has a single cutter head.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is the combination screw driver that discloses a kind of bull, comprise handle of a knife, cutter head and knife bar, described knife bar and handle of a knife are all cylindrical, described knife bar is connected on handle of a knife, described handle of a knife forms by two sections, be threaded connection between two sections, the chain connection of on average arranging on one section handle of a knife has the knife bar of three word cutter heads, the chain connection of on average arranging on another section handle of a knife has the knife bar of three cross cutter heads, knife bar rotatable 90 the degree make it with handle of a knife in vertical state.

As preferably, described handle of a knife is provided with the cylinder shape groove with knife bar, cutter head collaboration, and the end that described cylinder shape groove coordinates with cutter head is large, the convenient cutter head that takes out.

As preferably, the knife bar of described three word cutter heads, diameter by little to greatly 2mm, 3mm, 5mm.

As preferably, the knife bar of described three cross cutter heads, diameter by little to greatly 2mm, 3mm, 5mm.

As preferably, handle is provided with netted decorative pattern and increases friction.

Technical conceive of the present utility model is, with a plurality of knife bars by structural design connect with same handle of a knife on, two handle of a knifes screw by screw thread again and make it convenient when in use, and power used when making the operation screwdriver by such structure is less more laborsaving.

Beneficial effect: the utility model has reduced the trouble of choosing applicable driver bit, screwdriver can be selected a word and two kinds of cutter heads of cross and can select to be fit to the tip size of screw size, greatly improved operating efficiency, and simple in structure, with low cost, use, easy to carry.

Description of drawings

By reference to the accompanying drawings, other characteristics of the present utility model and advantage can become clearer from the explanation of the preferred embodiment that principle of the present utility model made an explanation below by giving an example.

Fig. 1 is a kind of apparatus structure schematic diagram of embodiment of the combination screw driver of a kind of bull of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:

As shown in Figure 1, the combination screw driver of a kind of bull comprises six cutter heads 3, knife bar 4 and two handle of a knifes 1.

Knife bar 4 is connected on handle of a knife 1 by hinge 5, knife bar 4 outwards 90-degree rotation make it with handle of a knife 1 in vertical state.

Knife bar 4 can be embedded in the security that increases screwdriver in handle of a knife 1 with this obsolete the time, can produce knife bar 4 come along hinge 5 when with screwdriver the time.The cylinder shape groove 2 that coordinates with knife bar 4 is arranged on described handle of a knife 1, larger at the groove that coordinates the cutter head position, conveniently pull with hand cutter head 3 knife bar 4 is produced.

Described screwdriver has two handle of a knifes, and the knife bar of a word cutter head and cross cutter head is housed respectively, and two handle of a knifes can screw by screw thread 6, at least even 3 knife bars of chain connection on a described handle of a knife.There is netted decorative pattern to increase friction on described handle 1.

Certainly, every section handle of a knife can fill three knife bars incessantly, can also according to design, fill four or more knife bar and cutter head, but mentality of designing be identical.

Although described by reference to the accompanying drawings embodiment of the present utility model, those of ordinary skills can make various distortion or modification within the scope of the appended claims.
