Description
Technical field
The utility model relates to machine tool technical field, is specifically related to a kind of screwdriver.
Background technology
Screwdriver, since its invention, has been widely used in the field such as Automatic manual transmission, furniture installation, has become people's daily life, produces one of most important instrument.At present, conventional screwdriver has two kinds of structures, one is single cutter head, this structure is easy to use, be easy to carry, but use word screw and a Philip's head screw due to often a large amount of in installation, when operating, need to carry many screwdriver of different cutter head model, add labour intensity, reduce efficiency, one is also had to be comprise knife bar and bit package, multiple cutter head is placed in bit package, during use, taking out required cutter head is mounted on knife bar, this structure is applicable to the screw of Multiple Type, convenient, fast, but when operating, bit package must be carried, but due to cutter head small volume, be easy to lose, operation is made troubles.
Meanwhile, the handle of existing screwdriver is generally larger cylindric of diameter, so that palm grip, completes the operation turning screw (screw or unscrew screw).When screw is longer, often need palm and wrist to require great effort to screwdriver and the rotation of repeatedly low-angle (being less than 180 degree of angles), so that hand is easily ached, turned, the time of operation is longer.
The cutter head of model can only screw or unscrew an a kind of model screw, uses limited, needs to improve.
Utility model content
For the problems referred to above, the utility model provides a kind of screwdriver, easy to use, laborsaving.
In order to solve the problem, the technical scheme that the utility model provides is:
A kind of screwdriver, comprises handle, also comprises some bodies of rod, the bottom of this body of rod is provided with the first cutter head, top is provided with the first external screw thread, and described handle is provided with some cavitys for holding the described body of rod, and the bottom of described handle is provided with the internal thread matched with described first external screw thread.
When not using, the body of rod is placed in cavity, not fragile, also can not hurt sb.'s feelings, also be easy to carry meanwhile.Some bodies of rod can arrange the first cutter head of different model, and the scope of application is wider.
Preferably, the top of the described body of rod is provided with the second cutter head, and bottom is provided with the second external screw thread matched with described internal thread.
Second cutter head and the first cutter head dissimilar, the second cutter head can be blossom type.
Preferably, described first cutter head is circular, and the thickness at the edge of described first cutter head along the circumferential direction evenly increases.
First cutter head can adapt to the screw of the yi word pattern of different size, and the scope of application is wider.
Preferably, the circumferential size at the middle part of described handle is greater than the circumferential size on top.
Screw or unscrew when not needing more energetically, by the top of rotary handle, the rotation of a fixing turn can be completed fast; When needs more energetically time, exerted a force by the middle part of handle.Such design is laborsaving, avoid handle to ache, and efficiency is high simultaneously.
Preferably, the described body of rod is provided with luminescent layer.
Luminescent layer can be silver-colored light powder coating; There is provided light source when dark, improve work accuracy.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by being provided with multiple body of rod, and avoid first, second cutter head to damage, also not easily hurt sb.'s feelings, simultaneous adaptation is wider; By the design of handle uniqueness, avoid handle to ache, efficiency is high simultaneously; Increase luminescent layer and provide light source when dark, improve work accuracy.

Fig. 1 is the top view of handle of the present utility model;
Fig. 2 is the front view of handle of the present utility model;
Fig. 3 is the front view of the body of rod of the present utility model;
Fig. 4 is the structure for amplifying schematic diagram of the first cutter head of the present utility model.
In figure: 1, handle, 2, the body of rod, the 3, first cutter head, the 4, first external screw thread, 5, cavity, 6, internal thread, the 7, second cutter head, the 8, second external screw thread, 9, luminescent layer.
Detailed description of the invention
Below the utility model is described further:
Composition graphs 1-4: a kind of screwdriver, comprises handle 1, also comprises some bodies of rod 2, the bottom of this body of rod 2 is provided with the first cutter head 3, top is provided with the first external screw thread 4, and handle 2 is provided with some cavitys 5 for holding the body of rod 2, and the bottom of handle 1 is provided with the internal thread 6 matched with the first external screw thread 4.
When not using, the body of rod 2 is placed in cavity 5, not fragile, also can not hurt sb.'s feelings, also be easy to carry meanwhile.Some bodies of rod 2 can arrange the first cutter head 3 of different model, and the scope of application is wider.
The top of the body of rod 2 is provided with the second cutter head 7, and bottom is provided with the second external screw thread 8 matched with internal thread 6.
Second cutter head 7 and the first cutter head 4 dissimilar, in this enforcement, the second cutter head 7 is blossom type.
In the present embodiment, the first cutter head 4 is circular, and the thickness at the edge of the first cutter head 4 along the circumferential direction evenly increases.
First cutter head 4 can adapt to the screw of the yi word pattern of different size, and the scope of application is wider.
The circumferential size at the middle part of handle 1 is greater than the circumferential size on top.
Screw or unscrew when not needing more energetically, by the top of rotary handle 1, the rotation of a fixing turn can be completed fast; When needs more energetically time, exerted a force by the middle part of handle 1.Such design is laborsaving, avoid handle to ache, and efficiency is high simultaneously.
The body of rod 2 is provided with luminescent layer 9.
Luminescent layer 9 can be silver-colored light powder coating; There is provided light source when dark, improve work accuracy.
